Fleager, City Manager Rl " t SUBJECT: PLANNING COMMISSION ACTON REGARDING AGENDA ITEM 7C — rcc TENTATIVE TRACT MAP NO. 18698 AND SITE PLAN REVIEW NO. ra 08SPR01 VISTA BELLA TOWNHOMES tr.1 At their meeting of February 2, 2010, the Planning Commission received a report from City staff regarding the above-mentioned item, a request for approval of a 65- unit multi-family residential townhome development on 4.62 acres located at the southwest corner of Butterfield Ranch Road and St. Gaudens Drive. There were four public speakers, one of which was a representative from the Soboba Land of Luiseno Indians requesting that a Native American Monitor be present onsite during initial grading of the project for possible discovery of cultural artifacts. Mitigation Measures CR-1 and CR-2 requires that City approved archeologist and paleontologist meeting the standards of the Secretary of the Interior Professional Standards be present during all earthmoving activities. To address the Soboba Indians' concerns, the Commission added the following Condition of Approval: "The developer will allow representatives of tribes, at no cost to the developer or the City, within the project site in their Tribal Traditional Use Areas to observe and be present during initial grading. If any such representatives observe any archeological resource uncovered during initial grading, they shall bring the uncovered resource to the attention of the City's archeologist/paleontologist." The other three public speakers had concerns regarding view impacts, increased traffic, access from St. Gaudens Drive, and insufficient onsite parking and overflow parking onto Phidias Lane. The Commission explained that the City does not have a view ordinance; however the top of the tallest building is still approximately 20'-25' below the knoll behind the project site. The project's peak hour trips does not exceed the City's threshold of 50 or more peak hour trips, therefore a Traffic Impact Study was not required for the project. February 3, 2010 CM010-025 Page 2 St. Gaudens Drive is a local street designed to provide local residential access within communities. Relocating the main access onto Butterfield Ranch Road, a 6- lane major arterial is discouraged as it has been designed to carry large volumes of local and regional traffic. The residents of Phidias Lane requested that resident only parking be allowed on the street through a permitting system. The project meets all parking requirements by providing an attached two-car garage for each unit, and exceeding the required guest parking spaces by one stall (33 required, 34 provided). The project's Conditions of Approval requires that all garages be maintained and usable as parking spaces at all times (COA #13) and that all uncovered parking spaces remain unassigned for guest parking (COA #14). The Commission explained to the residents of Phidias Lane that the request for resident only parking on the street is a separate matter from the project and urged the residents of Phidias lane to approach the City Council in regards to street parking restrictions. Staff requested that the Commission take action on the roof and fencing material. The developer is proposing a composite slate roof material and white vinyl fencing for durability and ease of maintenance. Staff requested the Commission approve the project with natural slate or concrete tile roofing and wrought iron (tubular steel) fencing to be compatible with all other residential and commercial developments in the City and to provide for a higher quality aesthetic design. The Commission approved the composite slate roof material but denied the request for vinyl fencing. The following Conditions of Approval were amended/added: Condition of Approval #4 amended: MATERIAL COLOR MANUFACTURER Roof Material Dusk Grey Tamko/Lamarite Slate Composite Shingle Condition of Approval added: "Staff shall work with the developer regarding final fence design to represent color and materials consistent with the approved colors and materials palette." The Planning Commission unanimously approved the project subject to the Condition of Approval as amended and added, 5-0.

The subject site is 4.62-acres and is adjacent to single-family detached residential developments. This property size limits its opportunity to develop to the density established by the RM-3 zone, as it was previously designated. On October 11, 2005, as part of the Shoppes Residential/Park Residential project, the City Council adopted a General Plan Amendment and Zone Change to reduce the site's density to RM-2 High Density Residential of 25 dwelling units per acre (115 units total for the 4.62-acre site). The site acted as a "donor" transfer site, which transferred 46 units to "recipient" sites, which included the Shoppes Residential and the Park Residential sites, both zoned RM-2 High Density Residential. A RM-2 designation is considered a more appropriate indicator of the site's development potential and is more compatible with the surrounding single-family residential area. On February 14, 2008, Vista Bella Investment Properties, LLC (hereinafter referred to as "the Applicant"), submitted an application to the City for a Tentative Tract Map and a Site Plan Review for the Vista Bella Townhomes, in accordance with Chapter 16.76 and Appendix D, Article 11 of the Chino Hills Development Code. The original proposal included 70-units. Staff was concerned about extensive amount of grading and retaining walls that are required to accommodate the 70 units as well as the site plan layout and building separation requirements. Since that time, the project has been through several revisions and reviews with staff from all City departments, at which time they had an opportunity to provide the Applicant with comments for correction and/or conditions of approval. The Applicant has worked with staff to address and correct the concerns and have reduced the number of units to 65, as shown on the plans presented for approval by the Planning Commission. GENERAL PLAN CONSISTENCY The project site is designated as High Density Residential on the Chino Hills General Plan. This land use designation allows up to 25 dwelling units per acre. The proposed project is a multiple-family residential development, which is proposed at 14.07 dwelling units per acre. This density is significantly lower than the maximum permitted density per the General Plan. The proposed 65-unit townhome residential development is a permitted use within RM-2 zone; therefore, the project is consistent with the General Plan. The Vista Bella Townhomes will be a "for-sale" residential project with three to four- bedroom homes available to current and future residents of the City. The project would meet the following Housing Element provisions: Goal 5: Promote and encourage housing opportunities for all economic segments of the community, regardless of age, sex, ethnic background, physical condition or family size. P4 Meeting Date: February 2, 2010 Page: 5 SUBJECT: TENTATIVE TRACT MAP NO, 18698 SITE PLAN REVIEW NO. 08SPRO1 • Policy 1.1: Provide a variety of residential opportunities in the city, including large lot estates, low density single-family homes, medium density townhomes, and higher density condominiums and apartments. APPROVAL REQUIRED The Applicant is seeking an approval from the Planning Commission for the following: n Mitigated Negative Declaration and Mitigation Monitoring Program; and • Tentative Tract Map No. 18698 (for condominium purposes); and • Site Plan Review approval to allow the development of a multi-family residential complex on a 4.62-acre parcel. • ANALYSIS The following section discusses pertinent planning issues of the project, including development standards, parking, traffic, open space, architecture, and landscaping. Building Summary The project consists of 9 three-story residential buildings that vary in size from five to nine dwellings each. The plan summary below summarizes the floor plan, size, private open space square footage, and number of each plan in the complex. Building types are illustrated in the elevations and floor plans included in the project plans (Exhibit "A"). Plan Summary Plan Unit Type Average Unit Square Minimum Private Number in Footage (Including Open Space Project 2-car garage) Square Footage Plan 1A 3 bed/3.5 bath 1,699 210 15 Plan 1B 3 bed/ 3.5 bath 1,756 210 10 Plan 2A 3 bed/ 3.5 bath 1,768 1 210 13 Plan 2B 4 bed/4 bath 1,850 I 210 7 Plan 3A 4 bed/4 bath 1,796 210 10 Plan 3B 4 bed/4 bath 1,810 210 10 P5 Meeting Date: February 2, 2010 Page: 6 SUBJECT: TENTATIVE TRACT MAP NO. 18698 SITE PLAN REVIEW NO. 08SPRO1 Development Standards Building Height Within the RM-2 zone, the maximum building height is 42'-0". The proposed three-story residential buildings reach a maximum height of 38'-6", which is well within the maximum limit of 42'-0" set in the Development Code. Building Setback The project meets all required setbacks as shown in the table below. Building Setback Requirements Proposed Required I Meets Requirement? 1 Front Yard 35' 25' ( Yes (Along Butterfield Ranch Road) I Side Yard (interior) I 43' I 10' ( Yes Street Side Yard ( 43' 20' Yes (Along St. Gaudens Drive) I Rear Yard j 25' 10' ( Yes I Building Separation I 35' 35' I Yes Open Space and Lot Coverage Some of the public open space on the site is dedicated to the required front and interior side yard setbacks. The majority of the public open space is dedicated to passive and active use by the residents. A common open space area of 20,390 square feet located in the center of the development with amenities including a tot lot, a gazebo, and a decorative fountain will provide the residents with recreational needs. More extensive recreational needs of the residents of the project will be met through their use of neighborhood parks in the area and throughout the City, resulting on an impact on the City's recreational resources. The applicant is required to pay both State of California Quimby Act fees and the City's recreational impact fees to offset the impact of the project. P6 Meeting Date: February 2, 2010 Page: 7 SUBJECT: TENTATIVE TRACT MAP NO. 18898 SITE PLAN REVIEW NO. 08SPRO1 The project meets the open space and lot coverage requirements as shown in the table below. Open Space and Lot Coverage Requirements I Proposed I Required I Meets Requirement? Maximum Lot Coverage by 24% 60% Yes Buildings Private Open Space 210 SF per unit 1 210 SF (70 SF per { Yes floor) Common Open Space 20,330 SF (312 5,850 SF (90 SF per Yes SF per unit) unit) Total Open Space 33,980 SF (522 19,500 SF (300 SF Yes SF per unit) combined of private and common open space per unit) Parking The project proposes to provide 164 parking spaces on site. This consists of 130 spaces within the two-car garages attached to each unit, 34 guest parking spaces located throughout the community, two (2) mail delivery/pick-up spaces, and three (3) ADA parking spaces. Chino Hills' parking standards for RM-2 requires two covered spaces per unit, and one guest space for every two dwelling units, which totals 2.5 spaces per unit, Using the formula of 2.5 parking spaces per unit, the project would need to provide a minimum of 163 parking spaces, with 164 parking spaces proposed, the project meets the parking requirements. Access and Traffic The proposed project is located at the southwest corner of Butterfield Ranch Road and St. Gaudens Drive, across from the ball fields of Chino Hills High School. The primary access to the development will be off of St. Gaudens Drive, with the secondary access off of Butterfield Ranch Road. Both ingress/egresses off of Butterfield Ranch Road and St. Gaudens Drive are restricted to right-in, right-out traffic circulation only due to the existing median along Butterfield Ranch Road. The proposal will generate approximately 390 trips per day, with 44 vehicles per hour during the AM peak hour, and 48 vehicles per hour during the PM peak hour. The majority of the traffic related to Chino Hills High School is off of Pomona Rincon Road; therefore the Project will have minimal impact on traffic in the area. The Project trip generation does not exceed the City's threshold of 50 trips in the peak hour, and therefore, a Traffic Impact Study is not required. Due to the project's low trip generation, the City Traffic Engineer has determined that the project will not have a significant impact on the surrounding roadways and intersections. P7 Meeting Date: February 2, 2010 Page: 8 SUBJECT: TENTATIVE TRACT MAP NO. 18698 SITE PLAN REVIEW NO. 08SPR01 Architecture The architectural style incorporates a variety of building planes and massing which creates visual interest. Accent materials and treatment include stone veneer, vertical siding, awnings, window shutters, and balconies. A combination of parapet and hipped roof lines are used for articulation. The garages are located at the rear of the units with the private yard areas along the front of the buildings, creating a pedestrian scale streetscape along Butterfield Ranch Road. The existing trail along Butterfield Ranch Road will be maintained. Development of the site is consistent with the City's residential design standards and is architecturally compatible with the existing residential development surrounding the site. Three color schemes in warm earth tone palettes are proposed for the buildings. Colors and materials are illustrated on the elevations plans included in Exhibit "A". During the course of the project review, staff has worked with the applicant on several design elements; however there are two remaining items that have not been resolved. The remaining items in which staff is requesting the Commission take action on is the material for the unit's private yard fencing and the buildings' roof material. Private Yard Fencing The Development Code states that "All walls and fences shall complement the architectural style of the development within which they are located. All walls and fences shall be designed to be decorative, including architectural embellishments, whenever visible from any street and/or from common areas within a development. All walls and fences shall be constructed of durable materials such as masonry, masonry combination, stone, brick, concrete, wrought iron (tubular steel), or other type of material as may be approved by the Planning Commission or the Community Development Director for durability, aesthetics, and sound attenuation purposes." The Applicant is proposing stucco walls with white vinyl fencing and stone pilasters for each unit's private yard area. The Applicant stated that the white vinyl fencing would provide future homeowners with ease of maintenance and that the design complements the existing trail fencing along Butterfield Ranch Road. According to the project's acoustical analysis, sound walls at least five (5) feet high shall be constructed around the exposed perimeters of all first floor private patios facing Butterfield Ranch Road to mitigate for exterior noise impacts to a maximum of 65 dBA CNEL (see page 39 of MND). To mitigate for the exterior noise impacts, the Applicant is proposing to use tempered glass behind the fencing as a noise barrier. Prior to the issuance of building permits, the design of the sound walls shall be approved by the Community Development Department (Mitigation Measure NOI-2). Additionally prior to issuance of an occupancy permit, the completed sound walls shall be approved by the Community Development Department to ensure compliance with the mitigation measure (Mitigation Measure NOI-2). P8 Meeting Date: February 2, 2010 Page: 9 SUBJECT: TENTATIVE TRACT MAP NO, 18698 SITE PLAN REVIEW NO. 08SPRO1 Historically, it has been the City's policy to approve residential and commercial projects with wrought iron (tubular steel) fencing, which is an aesthetically pleasing, high quality material. Staff is recommending that the Planning Commission approve the project with a combination of the stucco wall with wrought iron (tubular steel) fencing for all the private yards, with the exception of the private yards along Butterfield Ranch Road, which shall comply with the Mitigation Measure NOI-2. Staff concurs with the applicant in using tempered glass behind the fencing along Butterfield Ranch Road to mitigate noise impacts. The final fencing color and material approved by the Planning Commission shall be added as a Condition of Approval. Roof Material The City's policy on all residential and commercial developments has been to use natural slate or concrete tile on all roofs. Natural slate or concrete tile is a durable material which provides depth and aesthetic quality to the buildings' architecture. The Applicant is proposing Lamarite Slate Composite Shingles for the buildings' roof material for ease of maintenance and durability. The composite shingles are manufactured from colorized mineral filled polymer to simulate the look of natural slate. The composite shingle is lighter in weight and thinner than natural slate or concrete tile roofing. Staff conducted a field study of homes in Newport Beach which use the same roof material as proposed by the applicant and believe that the composite slate does not have the same aesthetic quality as natural slate or concrete tiles. Additionally, natural slate or concrete tile is the roof material used on the existing residential developments in the City. Staff believes that sing composite slate on the proposed buildings would not be architecturally compatible with the residential communities in the neighborhood. Furthermore, the building elevations include strong entry statements at eye-level (approximately 10'-12' from grade) which will be highly visible to pedestrians and should reflect a higher quality material than the composite shingles. As part of the Site Plan Review, the Planning Commission has the authority to review the project's design elements including colors and materials to be used. Staff is recommending that the Planning Commission approve the project with natural slate or concrete tile roofing. All existing residential projects in the City use natural slate or concrete tile roofing materials. This will provide a high quality aesthetic design and compatibility with the existing residential developments in the City. The final roofing material approved by the Planning Commission shall be added as a Condition of Approval. Landscaping and Trail Staff has reviewed conceptual landscaping for the project. The project is conditioned to submit formal landscape and irrigation plans for review and approval (Condition of Approval #30). Typical plant material sizes range from 15-gallon trees to 36" boxed trees. The proposed landscaping has incorporated water conservation irrigation, minimized the use of turf and maximized the use of mulch and drought tolerant and P9 Meeting Date: February 2, 2010 Page: 10 SUBJECT: TENTATIVE TRACT MAP NO. 18698 SITE PLAN REVIEW NO. OBSPRO1 native plant species to comply with the State's AB 1881 and the Chino Hills Landscape and Water Conservation Guidelines. The project is proposing to improve the trail along Butterfield Ranch Road and St. Gaudens Drive to match the existing trail. The project is conditioned to comply with the City's trail standards including matching the existing trail fencing (Condition of Approval #32). Access Easement to School District Property The adjoining property to the west of the site is currently owned by the Chino Valley Unified School District and is land-locked. The tentative map initially proposed a 30' wide access easement at the southern end of the property where St. Gaudens Drive intersects with Phidias Lane, which would provide access to the school district property. The City received a comment letter from the School District requesting that the easement be widened to 37'-40' to provide for a side-walk and retaining walls. The 30' wide easement proposed meets City standards for a two-lane, private driveway access; therefore the City cannot require the Applicant to provide additional width. However, subsequent to receiving the School District's comment letter, the applicant met with the School District and has agreed to widen the easement to 37'. PUBLIC COMMENTS Notices of the public hearing regarding this project were mailed to property owners within a 300-foot radius of the project site on December 23, 2009, and was also published in the Chino Hills Champion on December 26, 2009. Aside from the comment letter from the School District discussed above, staff has not received any comment letters as of the writing of this report. However, staff was contacted by a neighboring resident inquiring about a petition regarding parking for the project. The concern was that the project does not provide enough on-site parking and that the future residents and guests of the project will park on St. Gaudens Drive and/or Phidias Lane. The project is meeting the City's parking requirements by providing two-car garages for each unit and is providing an excess of one (1) space for the required guest parking spaces (see Parking discussion on page 7). Conditions of approval have been added to the project to ensure that garages are used for parking and that all uncovered parking spaces remain as guest parking (Condition of Approval #13 and #14). The Applicant held a Community Meeting on January 14, 2010 which was attended by approximately.8 households (20 people) throughout the evening. The community voiced concerns regarding additional traffic generated by the project in relation to a.m. traffic generated by the high school, and traffic and parking on Phidias Lane. P10 Meeting Date: February 2, 2010 Page: 11 SUBJECT: TENTATIVE TRACT MAP NO. 18698 SITE PLAN REVIEW NO. 08SPRO1 A Traffic Impact Study is required by the City if the proposed development is forecast to generate 50 or more vehicle trips in the a.m. or p.m. peak hour. The project will generate 44 trips in the a.m. peak hour which does not exceed the City's traffic impact threshold, and will therefore have minimal impact on traffic even with the morning high school traffic. The project will have minimal impact to Phidias Lane as the residents of the complex will be entering along Butterfield Ranch Road or at the end of St. Gaudens Drive. In terms of parking, the project is conditioned to maintain garages as parking spaces and prohibits resident parking in the uncovered parking spaces so as to be available for guest parking (Condition of Approval #13 and #14). Overall comments were favorable and the project appeared to be well received. Neighboring residents appreciated that the proposed 14 dwelling units per acre is well below the permitted 25 dwelling units per acre designated by the RM-2 zoning: ENVIRONMENTAL DETERMINATION Based on an Initial Study prepared for the project pursuant to the California Environmental Quality Act (CEQA), environmental impacts associated with the following can be mitigated to less than significant levels with the imposition of mitigation measures contained in the proposed Mitigated Negative Declaration (Exhibit B): • Biological Resources (California Black Walnut Tree, wetlands, and nesting birds), • Cultural Resources (archaeological and paleontological), ▪ Hydrology and Water Quality • Noise (construction noise) Impacts to Biological Resources California Black Walnut Tree, wetlands, and nesting birds) would be significant unless mitigated. Mitigation Measures BIO-1 through BIO-3 are required of the Project. One (1) special status plant species, the Southern California Black Walnut is present on the site. The arborist report prepared for the Project anticipates the loss of all twenty-six (26) of the California Black Walnut Trees due to their size, health and condition. The report considers the trees to be unsafe. In addition to the 26 walnut trees, an additional 54 trees are proposed to be removed. These trees include eucalyptus, Mexican elderberry, and arroyo willow. According to the "Tree Protection, Replacement and Mitiaation Plan For: Vista Bella Townhomes, which has been peer reviewed by Bonterra, the City's biological consultant, the trees are in poor health and would not survive relocation. Due to site constraints, on-site tree replacement does not seem feasible, therefore, in order to reduce impacts to less than significant, Mitigation Measure BIO-3 requires the Applicant to pay cash in lieu in an amount based on an industry standard used by City's Landscape Architect, to the City to provide for the planting of trees in City parks or City owned open space for a total of 191 replacement trees (see Mitigation Measure BIO-3). P11 Meeting Date: February 2, 2010 Page: 12 SUBJECT: TENTATIVE TRACT MAP NO. 18698 SITE PLAN REVIEW NO. OBSPR01 One drainage feature, flowing generally along the northern perimeter of the property, possesses characteristics that would lend itself to California Department Fish and Game (CDFG) jurisdiction (i.e. supporting wetland/riparian vegetation). This feature collects mainly urban runoff from the larger developed watershed above it, and transmits it as surface sheet flow over an abandoned asphalt driveway onto Butterfield Ranch Road, where it flows onto the City's stormwater culvert system. The drainage feature does not lend itself to U.S. Army Corps of Engineers (USAGE) jurisdiction as it does not have a definable bed and bank, an Ordinary High Water Mark, nor soils deeper than one to two inches to assess hydric characteristics according to the project's Jurisdictional Evaluation. However, whether or not this drainage feature is considered to be under the CDFG and/or the USACE has not been determined formally by these agencies and would typically be done at the permit level, For purposes of analysis, the Initial Study assumed a "worst case" scenario in which this drainage area is considered to fall under the jurisdiction of the CDFG and/or the USAGE. The "worst case" scenario was formulated through site review and analysis by a qualified biologist and the preparation of the Jurisdictional Evaluation prepared for the Project. Mitigation Measure BIO-1 is intended to mitigate for this "worst case" scenario by requiring that permits be obtained from both the CDFG and/or USAGE if necessary and that the possible loss of jurisdictional waters be mitigated at a ratio of 3:1 either through acquisition of off-site credits at a maximum ratio of 3:1 in a mitigation area for similar resources established by the City, if available, or at another mitigation area acceptable to the CDFG and/or USAGE, Another drainage feature, in the form of a concrete v-ditch flows parallel to Butterfield Ranch Road along the eastern boundary of the project site but this feature does not lend itself to USAGE or CDFG jurisdiction as it was constructed as a cross-gradient brow ditch not remotely following and discernable historic drainage patterns. However, as described above, for purposes of the Initial Study a "worst case" scenario was formulated in which this drainage area is considered to fall under the jurisdiction of the CDFG and/or the USAGE and be mitigated at a ratio of 3:1. Based on the Biolonical Constraints Evaluation for the project, which has been peer reviewed by the City's environmental consultant, the site contains shrubs and trees that could be used for nesting migratory birds. Nesting migratory birds are protected under the federal Migratory Bird Treaty Act and the California Fish and Game Code. Mitigation Measure BIO-2 protects nesting migratory birds by requiring a nesting bird survey if vegetation is to be removed during the nesting migratory bird nesting season (February 1 to August 31). If nesting birds are found, clearing and construction activities within three-hundred (300) feet of the nest (five-hundred feet [500] for raptors) shall be postponed or halted until the nest is vacated and juveniles have fledged and there is no evidence of a second attempt at nesting. Limits of construction to avoid an active nest shall also be established. Impacts to Cultural Resources (archaeological and paleontological) would be significant unless mitigated. Mitigation Measures CR-1 and CR-2 requires monitoring by a qualified archaeologist during all earthmoving, grading, grubbing, trenching or other earth- P12 Meeting Date: February 2, 2010 Page: 13 SUBJECT: TENTATIVE TRACT MAP NO. 18698 SITE PLAN REVIEW NO. 08SPRO1 disturbing activities on the project site to protect significant fossils and paleontological resources. Impacts to Hydrology and Water Quality would be significant unless mitigated. The Project has the potential to discharge pollutants that may impact water quality. The on-site storm drain system will be designed to comply with the National Pollutant Discharge Elimination System (NPDES) standards to ensure that pollutants are not discharged into the storm drain system. Mitigation Measures HYD-1 and HYD-2 requires a final Water Quality Management Plan will be submitted by the applicant and approved by the City's Engineering Department. Impacts from Noise during construction and exterior noise impacts would be significant unless mitigated. To mitigate construction noise, Mitigation Measures N01-1 requires all construction equipment utilize noise reduction features. To mitigate exterior and interior noise impacts, NOI-2 and NOI-3 requires sound walls at least five (5) feet high shall be constructed around the exposed perimeters of all first floor private patios facing Butterfield Ranch Road and requires buildings be constructed with noise attenuation features, such as double paned windows and insulated walls. The implementation of the Mitigation Measures identified above would result in less than significant impacts to Biological, Cultural Resources, Hydrology and Water Quality, and Noise. Therefore, there is not substantial evidence that the Project would have a significant effect on the environment after incorporation of the mitigation measures. See Exhibit B for a list of mitigation measures.

PC 2010— A RESOLUTION OF THE PLANNING COMMISSION OF THE CITY OF CHINO HILLS ADOPTING A MITIGATED NEGATIVE DECLARATION AND APPROVING TENTATIVE TRACT MAP NO. 18698 AND SITE PLAN REVIEW 08SPR01 FOR A 65-UNIT TOWNHOME DEVELOPMENT (VISTA BELLA TOWNHOMES) ON A 4.62-ACRE PARCEL LOCATED AT THE SOUTHWEST CORNER OF BUTTERFIELD RANCH ROAD AND ST. GAUDENS DRIVE. THE PLANNING COMMISSION OF THE CITY OF CHINO HILLS DOES HEREBY RESOLVE AS FOLLOWS: SECTION 1. The Planning Commission does hereby make the following findings of fact: A. The Applicant, Wallace Design Group, the representative for Vista Bella Investment Properties, LLC, requested approval of Tentative Tract Map No. 18698 and Site Plan Review 08SPR01 to construct a 65-unit townhome development on a 4.62-acre parcel. B. The site is located at the southwest corner of Butterfield Ranch Road and St. Gaudens Drive, and is legally described as Assessor's Parcel Number (APN) 1028-351-35 as shown in the latest records of the Office of the Tax Assessor of the County of San Bernardino. C. The property is zoned RM-2 High Density Residential, and has a General Plan designation of High Density Residential. D. An Initial Study/Mitigated Negative Declaration was prepared in accordance with the California Environmental Quality Act ("CEQA"), the State CEQA Guidelines, and the City of Chino Hills Local Procedures for Implementing CEQA. The Initial Study/Mitigated Negative Declaration was available for public review from December 28, 2009 through January 26, 2010. E. The Planning Commission of the City of Chino Hills held a duly noticed public hearing on February 2, 2010, to review and consider the staff report prepared for the project, receive public testimony, and review all correspondence received on the project. SECTION 2. Based upon oral and written testimony and other evidence received at the public hearings held for the project, and upon studies and investigations made by the Planning Commission and on its behalf, the Planning Commission does hereby determine that the Initial Study has been prepared in compliance with the California 1 OF 7 P15 Environmental Quality Act of 1970, as amended, and the Guidelines promulgated thereunder, and further, pursuant to the provisions of Section 753.5 (c) Title 14 of the California Code of Regulations, the Planning Commission finds as follows: in considering the record as a whole, the Initial Study and Mitigated Negative Declaration, there is no evidence before this Planning Commission that the proposed project will have potential for an adverse impact on wildlife resources or the habitat upon which wildlife depends. Further, based upon substantial evidence contained in the Mitigated Negative Declaration, the staff report and exhibits, and information provided to the Planning Commission during the public hearing, this Planning Commission hereby rebuts the presumption of adverse effect as set forth in Section 753.5 (C-1-d) of Title 14 of the California Code of Regulations. SECTION 3. With regard to the request for approval of a Tentative Tract Map No. 18698, based upon oral and written testimony and other evidence received at the public hearings held for the project, and upon studies and investigations made by the Planning Commission and on its behalf, the Planning Commission does further find as follows: A. FINDING: The proposed subdivision, together with the provisions for its design and conceptual improvements, is consistent with the General Plan. FACT: The project site is designated as High Density Residential on the General Plan and is zoned RM-2 High Density Residential. The approval of the Tentative Map for condominium purposes will provide the platform for development of the for-sale townhome project. This is consistent with Goal 5 of the General Plan Housing Element, which is to promote and encourage housing opportunities for all economic segments of the community, regardless of age, sex, ethnic background, physical condition, or family size. Additionally, the proposed subdivision supports Policy 1.1 of the General Plan to provide a variety of residential opportunities in the city, including large lot estates, low-density single-family homes, medium density townhomes, and higher density condominiums and apartments. B. FINDING: The site is physically suitable for the type and proposed density of the development. FACT: The 4.62-acre project site is located in an area that is fully developed with urban uses, including all necessary infrastructure. The site is physically suitable at the current density of 14 dwelling units per acre for multiple-family homes in that the project meets all applicable standards for development, per the Chino Hills Development Code, including setbacks, lot coverage, and parking as fully detailed in the Planning Commission staff report for this project, which is incorporated herein by reference. 2 OF 7 P16 C. FINDING: The design of the subdivision or the proposed conceptual improvements are not likely to cause substantial environmental damage or substantially or avoidably injure fish or wildlife or their habitat. FACT: The proposed subdivision is located in an area that is fully developed with urban uses. One (1) special status plant species, the Southern California Black Walnut is present on the site. The arborist report prepared for the Project anticipates the loss of all twenty-six (26) of the California Black Walnut Trees due to their size, health and condition. The report considers the trees to be unsafe. In order to reduce impacts to less than significant, the loss of twenty-six (26) California Black Walnut trees is mitigated for in Mitigation Measure BIO-3 in the project's Mitigation Monitoring Program. No other habitat or species of special concern are present or expected to occur on the Project site because of the high levels of site disturbance and the fact that the site is highly vegetated with ruderal vegetation, including a high density of non-native, invasive plant species. No mitigation is required for listed wildlife species. D. FINDING: The design of the subdivision or the type of improvements will not conflict with easements acquired by the public at large for access or • use of property within the proposed subdivision. FACT: The design of the subdivision has considered all easements for the public at large for access or use of the property. The tentative map is proposing a 30' wide access easement at the southern end of the property where St. Gaudens Drive intersects with Phidias Lane. The proposed easement will provide access for the currently land-locked parcel adjoining the subject property. E. FINDING: The design of the subdivision provides, to the extent feasible, passive or natural heating and cooling opportunities. FACT: Natural heating and cooling opportunities will be considered during the construction plan check for the residential units proposed for the project. Also, the landscape plan incorporates extensive use of trees and vegetation on site, which will help to reduce the effects of urban heat on site. F. FINDING: The proposed subdivision of land, its design, density and type of development and improvements conform to the regulations of the Development Code and the regulations of any public agency having jurisdiction by law. FACT: The proposed lot is in the RM-2 zone, which allows a maximum density of 25 units per acre. The proposal is for 14 units per acre, which is below the allowable density of 115 units in the zone. The proposed project meets all development code standards for the RM-2 zone, including 3 OF 7 P17 setbacks, height limits, open space, parking, circulation and access, and landscaping. Best Management Practices are incorporated into the plans to comply with air and water quality requirements of various agencies in the region. Construction plans are required to comply with standard engineering practices and the California Building Code. SECTION 4. With regard to the request for approval of Site Plan Review 08SPR01, based upon oral and written testimony and other evidence received at the public hearing held for the project, and upon studies and investigations made by the Planning Commission and on its behalf, the Planning Commission does further find as follows: A. Finding: The proposed development plan is consistent with the General Plan. Fact: The proposed plan is for the development of 65 high density residential units designed as townhomes. This is consistent with the Goal 5 of the General Plan Housing Element, which is to promote and encourage housing opportunities for all economic segments of the community, regardless of age, sex, ethnic background, physical condition, or family size. Additionally, the plan supports Policy 1.1 of the General Plan to provide a variety of residential opportunities in the city, including large lot estates, low-density single-family homes, medium density townhomes, and higher density condominiums and apartments. B. Finding: The nature, condition, and development of the adjacent uses, buildings and structures have been considered, and the use will not adversely affect, or be materially detrimental to these adjacent uses, buildings, or structures. Fact: The proposed townhome development is located on a parcel that is surrounded by urban land uses: to the north is an existing detached condominium development; to the west is a vacant, medium- density residential property; to the east is Chino Hills High School; and to the south are existing single-family residential homes. The development of additional residential units within this setting is an appropriate use for this parcel as it is consistent with the General Plan and Zoning as indicated in Section A above. C. Finding: The site is of adequate size and shape to accommodate the use and proposed buildings. Fact: The project site is approximately 4.62 acres, of irregular shape, and is zoned for high density residential development. The maximum allowable development of the site is 25 dwelling units per acre. The proposal is for a 65-unit townhome development, which is a density of 4 OF 7 P18 14.07 dwelling units per acre and is below the allowable density. The project site provides adequate interior circulation and parking, setbacks, building separations, landscaping, and access from public roads, as well as approximately 20,390 square feet of open space and amenities for the residents. As such, the site adequately accommodates the proposed use and buildings. D. Finding: The proposed use complies with all applicable development standards of the zoning district. Fact: The proposed project meets all development code standards for the RM-2 zone. The minimum setback requirements for all yards and minimum building separation of 35' have been met, and the maximum height of the buildings is 38'-6", which is below the 42'-0"-foot maximum allowed by the Development Code. Each dwelling unit has approximately 210 square feet of private open space, and more than 20,330 square feet of common open space, which exceeds the minimum requirement of 300 square feet of combined open space required per unit. The parking provided meets the development code standard of 2.5 spaces per unit. Landscape plans for the project also meet the minimum standards set in the Development Code. E. Finding: The proposed use observes the spirit and intent of the Development Code. Fact: The proposal is for a residential development in a high density residential zoning district. All Development Code standards have been met in the design of the project, as enumerated in Sections C and D above. The project is consistent with the purpose and intent of the Development Code. SECTION 5. The Planning Commission of the City of Chino Hills does hereby adopt the Mitigated Negative Declaration, and approve Tentative Tract Map No. 18698 and Site Plan Review 08SPR01, subject to the findings included within this resolution and subject to the Conditions of Approval, and the Project Plans labeled as Exhibit "A". 5 OF 7 P19 SECTION 6.

A location map is attached as Exhibit A. The Project site is designated as High Density Residential in the City's General Plan, and zoned RM-2 (High Density Residential), which allows up to 25.0 dwelling units per acre. The proposed density of the Project is 14 dwelling units per acre. The Project Site Plan is attached as Exhibit B. Tentative Tract Map 18698 and Site Plan Review 08SPR01 are required for Project entitlements, construction and operation. This Initial Study includes all phases of Project implementation and operation. Based on the analysis contained in this Initial Study, impacts to Aesthetics, Agriculture Resources, Air Quality, Geology/Soils, Hydrology/Water Quality, Land Use and Planning, Mineral Resources, Population/ Housing, Public Services, Recreation Transportation/Traffic, and Utility/Services Systems would have a less than significant impact on the environment. Impacts to Biological Resources (California Black Walnut Tree, wetlands, and nesting birds) would be significant unless mitigated. Mitigation Measures, BIO-1 through BIO-3 are required of the Project. Impacts to Cultural Resources (archaeological and paleontological) would be significant unless mitigated. Mitigation Measures CR-1 and CR-2 are required of the Project. Impacts to Hydrology and Water Quality would be significant unless mitigated. Mitigation Measures HYD-1 and HYD-2 are required of the Project. Impacts from Noise would be significant unless mitigated. Mitigation Measures NOI-1 and NOI-2 are required of the Project. The implementation of the Mitigation Measures identified above would result in less than significant impacts to Biological, Cultural Resources, Hydrology and Water Quality, and Noise. Therefore, there is not substantial evidence that the Project would have a significant effect on the environment after incorporation of the mitigation measures. See Exhibit D for a list of mitigation measures. Information and analysis provided in this document indicate that these mitigation measures would reduce the Project's potential environmental impacts to a less than significant level. Based on this finding, a Mitigated Negative Declaration is being recommended for adoption. 1. INTRODUCTION Purpose and Scope This Initial Study serves as the environmental review of the proposed Project, as required by the California Environmental Quality Act (CEQA), Public Resources Code Section 21000 et seq., 1 Vista Bella Townhomes (TTM 18698 and 08SPRO1) December 23, 2009 P57 the State CEQA Guidelines, and the City of Chino Hills' Local Guidelines for Implementing CEQA. In accordance with Section 15063 of the State CEQA Guidelines, the City is required to prepare an Initial Study to determine if the Project may have a significant effect on the environment. This Initial Study is intended to be an informational document providing the Planning Commission, other public agencies, and the general public with an objective assessment of the potential environmental impacts that could result from the implementation of the Project. Incorporation by Reference This Initial Study is based in part on the information and analysis contained in other environmental and planning documents. These documents are hereby incorporated by reference in their entirety into this Initial Study, as authorized by Section 15150 of the State CEQA Guidelines. All of the documents incorporated by reference are listed in Section 8 of this Initial Study. 2. EVALUATION OF ENVIRONMENTAL IMPACTS An Environmental Checklist Form (Form) has been used to evaluate the potential environmental impacts associated with the proposed Project. The Form has been prepared by the Resources Agency of California to assist local governmental agencies, such as the City of Chino Hills, in complying with the requirements of the Statutes and Guidelines for implementing the California Environmental Quality Act. The Form has been used by the City of Chino Hills to review the effects of the proposed Project with respect to the following environmental factors. Based on the analysis in this Initial Study, the following environmental factors are considered "Less Than Significant with Mitigation Incorporated" as a result of the proposed Project: ❑ Aesthetics ® Hydrology/Water Quality ❑ Population/Housing ❑ Agriculture Resources ❑ Hazards & Hazards ❑ Public Services Materials ❑ Air Quality ❑ Land Use and Planning ❑ Recreation IN Biological Resources ❑ Mineral Resources ❑ Transportation/Traffic ❑ Cultural Resources ® Noise ❑ Utilities/Service Systems ❑ Geology/Soils In the Form, a series of questions is asked about the Project for each of the above-listed environmental factors. A brief explanation is then provided for each question on the Form. There are four possible responses to each question: 2 Vista Bella Townhomes (TTM 18698 and 08SPR01) December 23, 2009 P58 A. Potentially Significant Impact. This response is used when the Project has the potential to have an effect on the environment that is considered to be significant and adverse. B. Less Than Significant with Mitigation Incorporated. This response is used when the Project has the potential to have a significant impact, which is not expected to occur because mitigation measures have been incorporated into the Project design in order to reduce the impact to a less than significant level. C. Less Than Significant Impact. This response is used when the potential environmental impact of the Project is determined to be below known or measurable thresholds of significance and thus would not require mitigation or adherence to existing policies, regulations, and/or design standards would reduce the impact of the Project to a less than significant level. D. No Impact. This response is used when the proposed Project does not have any measurable impact. 3 Vista Bella Tovinhomes (TTM 18698 and 08SPRO1) December 23, 2009 P59 3. ENVIRONMENTAL DETERMINATION On the basis of this initial evaluation, I find that: O The proposed Project could not have a significant effect on the environment, and a Negative Declaration will be prepared. lil Although the proposed Project could have a significant effect on the environment, there will not be a significant effect in this case because the mitigation measures, described in Exhibit C (attached), have been added to the Project. A Mitigated Negative Declaration will be prepared. D The proposed Project may have a significant effect on the environment, and an Environmental Impact Report is required. O The proposed Project may have a potentially significant impact unless mitigation is incorporated, but at least one of the impacts has been: 1) adequately analyzed in an earlier document pursuant to applicable legal standards and 2) addressed by mitigation measures based on the earlier analysis as described on the attached sheets. An Environmental Impact Report is required, but it is to analyze only those impacts that have not already been addressed. D Although the proposed Project could have a significant effect on the environment, because all potentially significant effects (a) have been analyzed adequately in an earlier Environmental Impact Report (EIR) or in a Negative Declaration pursuant to applicable legal standards, and (b) have been avoided or mitigated pursuant to that earlier EIR or Negative Declaration, including revisions or mitigation measures that are imposed upon the proposed Project, nothing further is required. .

PROJECT BACKGROUND: Project Title: Vista Bella Townhome Project, Tentative Tract Map 18698 and Site Plan Review 08SPRO1 Location: Southwest corner of Butterfield Ranch Road and St. Gaudens Drive, 4 Vista Bella Townhomes (TTM 18698 and 08SPRO1) December 23, 2009 P60 Site Size: 4.62 acres APN: 1028-351-35 Proposal: The Project proposes the grading, construction, and operation of 65 condominium units. The Project includes related parking, driveways, landscaping, site and storm drainage improvements, and installation of on- site utilities to serve the development. Applicant: Wallace Design Group 28836 Via De Luna Laguna Niguel, California 92677 Lead Agency Staff: Betty Donavanik, Senior Planner, Telephone: (909) 364-2777 Project Description: The Project consists of Tentative Tract Map 18698, consisting of one (1) lot for condominium purposes, and Site Plan Review 08SPRO1 for the layout of the buildings and site features, as well as the architectural design of the buildings. The Project site is currently designated by the City General Plan as High Density Residential (25 dwelling units per acre) and zoned RM-2. The proposed Project density is 14 dwelling units per acre, and is consistent with the General Plan and Zoning designations. The design of the Project consists of 9 three-story residential buildings. Units consist of three and four bedroom units ranging in size from 1699 square feet to 1850 square feet. Parking for each unit is provided under the units within garages. Uncovered visitor parking is provided throughout the site. The main entrance to the Project is located off of St. Gaudens Drive and a secondary entrance is located off Butterfield Ranch Road. Project Site Conditions: The site is currently vacant with vegetation consisting primarily of eucalyptus woodland with an understory of ruderal plant species. California black walnut, Peruvian pepper, and blue elderberry trees also are present on the site. An access road traverses the northern boundary of the Project site. Runoff from neighboring properties to the south accumulates as a rivulet of water that runs down the road and supports a variety of plant species. Along the eastern boundary of the Project site, adjacent to Butterfield Ranch Road, runs a cemented v-ditch, in which surface water runoff flows east from the Project site to a rock-bottomed detention basin and culvert that drains runoff off site to the north underneath Butterfield Ranch Road. The site topography slopes downward from the west to the east. The southwestern portion of the site contains a knoll with a slope of approximately 15% to 50%. Surrounding Land Uses The site is vacant and is surrounded by residential development, as shown in the Table 1 below. Table 1.

EXPLANATION OF THE ITEMS MARKED ON THE ENVIRONMENTAL CHECKLIST FORM Checklist Item I. Aesthetics a. No Impact (Scenic Vista). An analysis of a scenic vista focuses on the impacts of a project on views of natural features that provide a context or setting for a community or geographic area (i.e. mountains, unique natural features, open spaces, etc.) The Project site itself is not considered a scenic vista in this context as it is adjacent to an existing roadway and surrounded by existing development. In addition, Policy 1-2 of the General Plan Land Use Element requires the preservation of significant natural features such as ridges, knolls, and vistas. Figure 15-1 of the Municipal Code identifies prominent knolls and ridgelines that are considered unique natural resources and therefore could be considered scenic vistas. The Project site is not located within an identified area that is intended to preserve ridges, knolls or vistas. As such, there will be a less than significant impact on Scenic Vistas. No mitigation measures are required. b. No Impact (Scenic Resources-State Scenic Highway). Butterfield Ranch Road, which is adjacent to the site, is not designated as a State Scenic Highway. Therefore, no impacts to scenic resources (i.e. significant trees, rockoutcroppings, or historic buildings) within a State Scenic Highway will occur. No mitigation measures are required. c. Less Than Significant (Visual Character). The existing visual character of the site is vacant land with vegetation consisting of trees and ruderal plant species. The southwestern portion of the site contains a knoll with a slope of approximately 15% to 50%. The knoll is not identified as a significant Citywide natural feature based on Figure 15-1 of the Municipal Code, however, it does add to the visual character of the site. Because of the existing location of the intersection of St. Gaudens Drive and Phidias Lane, the knoll area is the only practical location to construct the primary access to the project without constructing two access driveways on Butterfield Ranch Road. In order to construct the primary access, the knoll will be altered. The construction of two vegetated crib walls which will help minimize the impacts on the knoll. 16 Vista Bella Townhomes (TTM 18698 and 08SPRO1) December 23, 2009 P72 The visual character of the site also applies to the "after developed" condition. Constructing multiple-family units on the site would change the existing visual character of the site as currently seen by surrounding residences and people traveling on the adjacent roadways. This would be the case in any situation where vacant land is developed. The Project has been evaluated against the requirements of Municipal Code Section 16.10.040, "Minimum Residential Design Standards", Section 16.10.060, "Multifamily Housing-Additional Standards", and Section 16.11, "Multiple-Family Ownership Housing." These standards and guidelines are intended to ensure that the Project meets the design and architectural quality standards of the City and is compatible with its surroundings. In the opinion of City staff, the project meets these requirements. A formal approval is still required by the Planning Commission, however, it is mandatory that the Project meets these requirements. Therefore, negative impacts to the visual character of the site are not forecast to occur as a result of development. Based on the above analysis, impacts in regard to the visual character of the site as a result of the Project are considered less than significant. No mitigation measures are required. d. Less Than Significant Impact (Light/Glare). The Project will create lighting typical of multiple-family residential development (i.e. security lighting, accent lighting, etc.) that will increase light levels in the area. Municipal Code Section 16.48.040 contains performance standards which require all lights and glare associated with the Project to be shielded or directed so as to not illuminate adjacent properties or cause glare to motorists. This is a mandatory requirement that will be part of the Project Conditions of Approval. Compliance is verified through the plan review and plan check process No mitigation measures are required. Checklist Item II. Agricultural Resources a. No Impact (Farmland Conversion). Based on the most recent data (2004) from the Farmland Mapping and Monitoring Program prepared by the California Department of Conservation, the Project site is not designated as containing Prime Farmland, Unique Farmland, or Farmland of Statewide Importance. No mitigation measures are required. b. No Impact (Zoning). The zoning of the site is RM-2, High Density Residential, so it is not intended to be used for agricultural purposes. The site is not covered by a Williamson Act Contract. No mitigation measures are required. c. No Impact (Land Use). Development of the site consists of 65 townhomes and related infrastructure. The site is surrounded by existing residential development and Chino Hills High School across Butterfield Ranch Road. There are no adjacent agricultural uses that would be impacted as a result of the Project. No mitigation measures are required. Checklist Item III. Air Quality a. No Impact (Air Quality Plan). The South Coast Air Quality Management District (SCAQMD) has jurisdiction over development in the South Coast Air Basin (Basin). The project site is located in the Basin. The Air Quality Management Plan (AQMP) is 17 Vista Bella Townhomes (TTM 18598 and 08SPR01) December 23, 2009 P73 SCAQMD's on-going program for meeting the federal and state air quality standards within the Basin. The AQMP contains a number of land use and transportation rules and regulations designed to help the region meet the air quality standards set forth in the AQMP. A project is considered consistent with the AQMP if it will not result in an increase in the frequency or severity of existing air quality violations, or cause or contribute to new violations, or delay timely attainment of air quality standards or the interim emissions reductions specified in the AQMP. Based on the Vista Bella Townhouse Project Air Quality Assessment by Impact Sciences, Inc.. January 2008, the project will not exceed construction or operational emission thresholds established by the SCAQMD. No mitigation measures are required. b. Less Than Significant Impact (Air Quality Standards). The CEQA Guidelines indicate that a significant impact would occur if the proposed Project would violate any air quality standard or contribute significantly to an existing or projected air quality violation. Construction Impacts Construction: Impacts for short-term construction are a result of site preparation and grading, construction of the buildings, the parking areas, and related improvements. Project-generated construction-related emissions were modeled using the California Air Resources Board (CARB)-approved URBEMIS 2007 Version 9.2.4 (URBEMIS) computer program as recommended by the South Coast Air Quality Management District (SCAQMD). URBEMIS is designed to model construction emissions for land development projects and allows for the input of project-specific information. Project-generated emissions were modeled based on project specific information in order to estimate reasonable worst-case conditions. Based on the Vista Bella Townhouse Protect Air Quality Assessment prepared by Impact Sciences, Inc., the Project's, air pollutant emissions generated during all phases of the Project construction are projected to be less than the SCAQMD regional construction emission thresholds as shown in Table 2 below: Table 2. Construction Emissions Maximum Daily I Emissions (pounds per day) Emissions 1 VOC I NOx I CO I SO2 PMio ( PM 2.5 Project I 7.62 ( 84.97 I 37.01 I 0.06 I 14.01 I 5.72 Regional Threshold I 75 ( 100 I 550 I 150 I 150 I 55 Exceeds Regional NO NO NO NO NO NO Threshold? _ace: Impact Sciences, Inc. 2009 However, in order to reduce air quality impacts to the maximum extent feasible, the following mitigation measures are recommended: AQ-1. Equipment used during rough and precise grading activities shall require the use of one of the following: Diesel oxidation catalysts or other amendment to achieve a 15 percent reduction in NOx emissions; or 18 Vista Bella Townhomes (TTM 18698 and 08SPR01) December 23, 2009 P74 An engine tier of three or higher; or 'An engine of year 2006 or newer. AQ-2. During project construction, construction equipment shall be properly maintained in accordance with manufacturer's specifications; maintenance shall include proper tuning and timing of engines. During maintenance, precautions shall be taken to ensure that fuel is not leaked onto the ground. Equipment maintenance records and equipment design specification data sheets shall be kept onsite during construction and subject to inspection by the SCAQMD. AQ-3. During project construction, the developer shall require all contractors to turn off all construction equipment and delivery vehicles when not in use. AQ-4. Prior to project construction, the project proponent will provide a traffic control plan that will describe in detail safe detours around the project construction site and provide temporary traffic control (i.e., flag person) during debris transport and other construction-related truck hauling activities. AQ-5. During project construction, onsite electrical hook ups shall be provided for electric construction tools including saws, drills and compressors, to eliminate the need for diesel powered electric generators. AQ-6. Grading activity shall not occur on days with an Air Quality Index forecast for San Bernardino County greater than 100 for particulates or ozone. The categories where grading shall not occur are: unhealthy for sensitive groups, unhealthy, very unhealthy, or hazardous. Air Quality Index forecasts can be obtained at the website: www.ai rnow.a ov/i n dex.cfm?acti on=ai rnow.showlocal&Cittrl D=211 Lon4-Term Operations Impacts Impacts from long-term operations are primarily a result of additional vehicle trips from the Project and to some extent the use of natural gas for space and water heating devices and equipment used for maintenance of the Project. Based on the Vista Bella Townhouse Project Air Quality Assessment. the Project will not exceed SCAQMD operational emission thresholds for CO, NOx, PMto, PM2.5, SO2, and VOC as shown in Table 3 below. No mitigation is required. Table 3.

Less Than Significant Impact (Cumulative Considerable Net Increase). The South Coast Air Basin is in non-attainment for carbon monoxide, PM2.5 and PMIo, and ozone, which means that the background level of those pollutants are, at times, higher than the ambient air quality standards. The Vista Bella Townhouse Protect Air Quality Assessment for the Project determined that the thresholds for the above referenced criteria pollutants would not be exceeded by the Project, therefore, impacts from the Project are not cumulatively considerable when included with other past, present, and future probable projects. No mitigation is required. d. Less Than Significant Impact (Sensitive Receptors, Pollutant Concentrations). Potentially Sensitive Receptors in the area are the single-family homes adjacent to the Project and concentrations of CO at intersections ("CO Hotspots"). Construction Localized Sianificance Threshold(LST)Analysis The SCAQMD LST document Final Methodoloav to Calculate Particulate Matter (PM) 2.5 and PM 2.5 Sianificance Thresholds includes lookup tables that can be used for projects less than 5 acres in size to determine the maximum allowable daily emissions that would satisfy the localized significance criteria. The allowable emission rate depends on the (1) Source Receptor Area (SRA) in which the project is located, (2), the size of the project site, and (3) the distance between the project site and the nearest sensitive receptor (e.g. residences, schools, hospitals). For purposes of this analysis the following parameters were used: 4 SRA: 33 (Southwest San Bernardino Valley) ® Site Size: 4.62 acres • Nearest Sensitive Receptors: Residential uses less than 25 meters (X feet) to the north, west, and south of the site. Based on the Vista Bella Townhouse Project Air Quality Assessment prepared by Impact Sciences, Inc., the Project's, LST emissions generated during construction are projected to be less than the SCAQMD's LST construction emission thresholds as shown in Table 4 below. No mitigation is required. Table 4.

I Source: Impact Sciences, Inc. Air Quality Assessment,January 2008 CO Hotsoot Analysis CO is the most notable source of emissions concentration at intersections because of motor vehicle idling. The Vista Bella Townhouse Project Air Quality Assessment evaluated nearby intersections where CO Hot Spots have the potential to occur. The analysis concluded that no intersection would exceed the state or federal 1-hour and 8-hour standards based on estimated future conditions. No significant CO hotspot impacts would 20 Vista Bella Townhomes (TTM 18698 and 08SPR01) December 23, 2009 P76 occur to sensitive receptors in the vicinity of the Project. No mitigation measures are required. e. Less Than Significant impact(Odors). The Project contains residential land uses that typically do not emit objectionable odors. During construction, odors from construction activities, such as application of building coatings and laying asphalt will occur. Due to the short-term nature of these activities and the residential nature of the project, both short-term and long-term odor impacts will be less than significant. No mitigation measures are required. f. Less Than Significant Impact (Generate Greenhouse Gas Emissions). On April 13, 2009, the Governor's Office of Planning and Research (OPR) submitted to the Secretary for Natural Resources its proposed amendments to the state CEQA Guidelines for greenhouse gas emissions, as required by Senate Bill 97. These proposed CEQA Guideline amendments would provide guidance to public agencies regarding the analysis and mitigation of the effects of greenhouse gas emissions in draft CEQA documents. The Natural Resources Agency will conduct formal rulemaking in 2009, prior to certifying and adopting the amendments, as required by Senate Bill 97. The rulemaking process will be completed by January 1, 2010, as required by Public Resources Code Section 21 083.05(b). This Initial Study uses the proposed amendments to the CEQA Guidelines, the OPR Technical Advisory on CEQA and Climate Chance, the Vista Bella Townhouse Protect, Climate Chancre Assessment prepared by Impact Sciences dated August 2009 (Appendix B) to analyze the impacts of Greenhouse Gas Emissions from the Project. Background Global Climate Change refers to alterations in weather features which occur across the Earth as a whole, such as temperature, wind patterns, precipitation, and storms. Global temperatures are modulated by naturally occurring atmospheric gases, such as water vapor, carbon dioxide, methane, and nitrous oxide. These gases allow sunlight into the Earth's atmosphere, but prevent radiative heat from escaping into outer space, thus altering the Earth's energy balance in a phenomenon called the greenhouse effect. "Greenhouse gas" or "greenhouse gases" includes but is not limited to: carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons and sulfur hexafluoride. (Reference: Health and Safety Code Section 38505(g).) The OPR Technical Advisory on CEQA and Climate Change recommends the following approach to the CEQA analysis. Identify Greenhouse Gas (GHG) Emissions: Lead agencies should make a good-faith effort, based on available information, to calculate, model, or estimate the amount of CO2 and other GHG emissions from a project s Determine Significance: As with any environmental impact, lead agencies must determine what constitutes a significant impact. In the absence of regulatory standards for GHG emissions or other scientific data to clearly define what constitutes a "significant impact", individual lead agencies may 21 Vista Bella Townhomes (TTM 18698 and 08SPR01) December 23, 2009 P77 undertake a project by- project analysis, consistent with available guidance and current CEQA practice. Mitigate Impacts: Mitigation measures will vary with the type of project being contemplated, but may include alternative project designs or locations that conserve energy and water, measures that reduce vehicle miles traveled by fossil-fueled vehicles, measures that contribute to established regional or programmatic mitigation strategies, and measures that sequester carbon to offset the emissions from the project Identify GHG Emissions Construction Emissions The proposed Project would result in emissions during construction. These emissions, primarily CO2, CI-14, and N2O, are the result of fuel combustion by construction equipment and motor vehicles. The other primary GHGs (hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride) are typically associated with specific industrial sources and are not expected to be emitted by the proposed Project. Table 5 lists the estimated GHG emissions associated with construction of the proposed Project. Table 5. GHG Construction Emissions GHG Emission Source Emissions (Metric Tons CO2elyear Construction 2010 1242.64 1 Construction 2011 1200.32 1 TOTAL ( 442.96 Annualized Over Project 14.77 Lifetime Source: Impact Sciences, Inc. 2009 Operational Emissions At full buildout, the Project would result in direct annual emissions of GHGs during Project operation. These emissions, primarily CO2, CH4, and N2O, are the result of fuel combustion from building heating systems and motor vehicles. Direct emissions of CO2 emitted from operation of the proposed Project are primarily due to natural gas consumption and mobile source emissions. The proposed project would also result in indirect GHG emissions due to the electricity demands of the proposed project. In addition to electrical demand, the project would also result in indirect GHG emissions due to water consumption, wastewater treatment, and solid waste generation. Table 6 lists the estimated GHG emissions associated with operations of the proposed Project. 22 Vista Bella Townhomes (TTM 18698 and 08SPR01) December 23, 2009 P78 Table 6. Estimated Operational GHG Emissions Operational Emissions Source GHG Emissions (MTCO2e/year) Construction(Annualized) Emissions) 14.77 1 Operational (Mobile) Sources 796.18 Area Sources 137.21 I Electrical Consumption 73.06 Solid Waste Generation 4.74 Water Supply 19.11 Wastewater Generation 3.79 I TOTAL 1,048.86 I Source: Impact Sciences, Inc. 2009 I Determine Significance: The OPR Technical Advisory on CEQA and Climate Chance states "The most difficult part of the climate change analysis will be the determination of significance. Although lead agencies typically rely on local or regional definitions of significance for most environmental issues, the global nature of climate change warrants investigation of a statewide threshold of significance for GHG emissions..." Table 7 compares the estimated GHG emissions of the proposed Project to the emissions for California. Table 7. Comparison of GHG Emissions Project vs. California Emitting Entity GHG Emissions (MTCO2e/year) Proposed Project Buildout 0.001048 I I California ( 483.87 Percent of State Emissions 0.00022% Source; Impact Sciences, Inc. 2009 I It is generally the case that an individual Project of this size is of insufficient magnitude by itself to influence climate change or result in a substantial contribution to the global GHG inventory. As shown in Table 7, the Project would contribute approximately 0.00022 percent to the annual state GHG inventory. In addition, while the SCAQMD has not formally adopted a significance threshold and has only drafted a threshold of 3,000 MTCO2e for residential projects, it could be used as an indicator of a Project's significance under CEQA. As shown in Table 6, the proposed Project would result in GHG emissions equal to approximately one third of the 3,000 MTCO2e draft threshold. For the reasons discussed in this section and because the project incorporates GHG reduction measures and design features, the project's GHG emissions would be less than significant. g) No Impact(Conflict with Plans to Reduce GI-IG Emissions) The primary planning legislation enacted by the State to address GHG Emissions is described as follows: 23 Vista Bella Townhomes (I 1 M 18698 and 08SPR01) December 23, 2009 P79 • Assembly Bill 32 (AB 32), the California Global Warming Solutions Act of 2006: AB 32 establishes a state goal of reducing GHG emissions to 1990 levels by the year 2020 (a reduction of approximately 25 percent from forecast emission levels) with further reductions to follow. The law requires the Air Resources Board (ARB) to establish a program to track and report GHG emissions; approve a scoping plan for achieving the maximum technologically feasible and cost effective reductions from sources of GHG emissions; adopt early reduction measures to begin moving forward; and adopt, implement and enforce regulations — including market mechanisms such as "cap and-trade" programs to ensure the required reductions occur. • Senate Bill 97 (SB 97): Enacted in 2007, SB 97amends the CEQA statute to clearly establish that GHG emissions and the effects of GHG emissions are appropriate subjects for CEQA analysis. It directs the Governor's Office of Planning and Research to develop draft CEQA Guidelines "for the mitigation of greenhouse gas emissions or the effects of greenhouse gas emissions" by July 1, 2009 and directs the Resources Agency to certify and adopt the CEQA Guidelines by January 1, 2010. • Senate Bill 375 (SB 375): Enacted in September 2008, SB 375 requires ARB to establish regional targets for reductions on GHG emission from the use of light duty vehicles associated with land use decisions; requires metropolitan planning agencies to create a Sustainable Community Strategy in their Regional Transportation Plans (RTP) to meet the GHG emissions targets established by ARB; requires that funding decisions for regional transportation projects be internally consistent within the RTP; aligns the Regional Housing Needs Assessment with the RTP; and provides CEQA relief (i.e. streamlining and exemptions) for projects that are consistent with the Sustainable Communities Strategy. As noted in the analysis under Checklist Item Illg above, the Project was analyzed using the OPR Technical Advisory on CEQA and Climate Chance: (Published June 2008) which is intended to address GHG Emissions in a manner consistent with the above described legislation. Therefore, the project is not in conflict with any plans to regulate GHG Emissions. Checklist Item IV. Biological Resources The following analysis is based on the Bioloeical Constraints Evaluation. Vista Bella Townhouses Project Site. City of Chino Hills. San Bernardino County. California_ by Impact Sciences, Inc., June 2008 and updated July 27, 2009,(Appendix C), the Jurisdictional Evaluation for the Vista Bella Townhomes Project by Impact Sciences dated December 17, 2009 (Appendix D), and the Tree Protection. Replacement and Mitication Plan For: Vista Bella Townhomes by Arborgate Consulting Inc. dated December 17, 2009 (Appendix E). These reports have been peer reviewed and approved by Bon Terra Consulting, the City's biological consultant. 24 Vista Bella Townhomes (TTM 18698 and 08SPRO1) December 23, 2009 P80 a. Less Than Significant with Mitigation Incorporated(Listed Plant Species). Listed Plant Species Based on the Biological Constraints Evaluation, one (1) special status plant species, the Southern California Black Walnut is present on the site. The remaining listed species contained in the CNDDB and CNPS databases are not present or expected to occur on the Project site because of the high levels of site disturbance and the fact that the site is highly vegetated with ruderal vegetation. The arborist report prepared for the Project (see Section IVe below) anticipates the loss of all twenty-six (26) of the California Black Walnut Trees due to their size, health and condition, The report considers the trees to be unsafe. In order to reduce impacts to less than significant, the loss of twenty-six (26) California Black Walnut trees is mitigated for in Mitigation Measure BI0-3 below. Listed Wildlife Species Based on the Biological Constraints Evaluation. it is considered unlikely that the Project site provides suitable habitat for any listed wildlife species. This is because the Project site contains ruderal vegetation, including a high density of non-native, invasive plant species, as well as the fact that the Project site is surrounded by development. No mitigation is required for listed wildlife species. b. Less Than Significant with Mitigation Incorporated (Riparian Habitat). See discussion in Checklist Item IVc below. b. Less Than Significant with Mitigation Incorporated (Wetlands). Based on the Jurisdictional Evaluation for the Project prepared by Impact Sciences, Inc., one drainage feature, flowing generally along the northern perimeter of the property, possesses characteristics that would lend itself to California Department Fish and Game (CDFG)jurisdiction (i.e. supporting wetland/riparian vegetation). This feature collects mainly urban runoff from the larger developed watershed above it, and transmits it as surface sheet flow over an abandoned asphalt driveway onto Butterfield Ranch Road, where it flows onto the City's stormwater culvert system. The drainage feature does not lend itself to U.S. Army Corps of Engineers (USACE) jurisdiction as it does not have a definable bed and bank, an Ordinary High Water Mark, nor soils deeper than one to two inches to assess hydric characteristics according to the Jurisdictional Evaluation. However, whether or not this drainage feature is considered to be under the CDFG and/or the USAGE has not been determined formally by these agencies and would typically be done at the permit level. For purposes of analysis, this Initial Study is assuming a "worst case" scenario in which these drainage area is considered to fall under the jurisdiction of the CDFG and/or the USACE. The "worst case" scenario was formulated through site review and analysis by a qualified biologist and the preparation of the Jurisdictional Evaluation prepared for the Project. Mitigation Measure BI0-1 below is intended to mitigate for this "worst case" scenario by requiring that permits be obtained from both the CDFG and/or USACE if necessary and that the possible loss of jurisdictional waters be mitigated at a ratio of 3:1 either through acquisition of off- site credits at a maximum ratio of 3:1 in a mitigation area for similar resources established by the City, if available, or at another mitigation area acceptable to the CDFG and/or USACE. 25 Vista Bella Townhomes (I I M 18698 and 08SPR01) December 23, 2009 P81 Another drainage feature, in the form of a concrete v-ditch flows parallel to Butterfield Ranch Road along the eastern boundary of the project site but this feature does not lend itself to USAGE or CDFG jurisdiction as it was constructed as a cross-gradient brow ditch not remotely following and discernable historic drainage patterns. However, as described above, for purposes of this Initial Study a "worst case" scenario was formulated in which this drainage area is considered to fall under the jurisdiction of the CDFG and/or the USAGE. Mitigation Measure BIO-1 below is intended to mitigate for this "worst case" scenario by requiring that permits be obtained from both the CDFG and/or USAGE if necessary and that the possible loss of jurisdictional waters be mitigated at a ratio of 3:1 either through acquisition of off-site credits at a maximum ratio of 3:1 in a mitigation area for similar resources established by the City, if available, or at another mitigation area acceptable to the CDFG and/or USAGE. 8I0-1: Prior to any activities that may impact on-site CDFG or USAGE jurisdictional areas, communications with the CDFG and USAGE shall be conducted to determine whether the agencies are interested in taking jurisdiction over the areas identified in the Biology Technical Study by Impact Sciences, Inc., dated July 27, 2009 and the Jurisdictional Evaluation by impact Sciences, Inc., dated December 17, 2009. If so, a Streambed Alteration Agreement notification shall be submitted to the CDFG, a jurisdictional delineation shall be submitted to the USAGE for formal determination about whether on-site waters fall under their jurisdiction and verification, and a 401 certification and/or waste discharge permit shall be submitted to the RWQCB. Any permit(s) shall contain verification to the City that the loss of wetlands has been mitigated through acquisition of off-site credits at a maximum ratio of 3:1 in a mitigation area for similar resources established by the City, if available, or at another mitigation area acceptable to the CDFG and/or USAGE. d. Less Than Significant with Mitigation Incorporated (Native Bird Nests) Based on the Biological Constraints Evaluation for the project, the site contains shrubs and trees that could be used for nesting migratory birds. Nesting migratory birds are protected under the federal Migratory Bird Treaty Act and the California Fish and Game Code. This is considered a potentially significant impact. Mitigation Measure 510-2 is recommended to mitigate impacts to less than significant: BIO-2: If active nests are located during pre-construction surveys, in accordance with California Department of Fish and Game (CDFG) guidelines, clearing and construction activities within three-hundred (300) feet of the nest (five-hundred feet [500] for raptors) shall be postponed or halted until the nest is vacated and juveniles have fledged and there is no evidence of a second attempt at nesting, as determined by a City approved biologist. Limits of construction to avoid an active nest shall be established in the field with flagging, fencing, or other appropriate barriers and construction personnel shall be instructed on the sensitivity of the nest areas. The biologist shall serve as a construction monitor during those periods when construction activities will occur near active nest areas to ensure that no inadvertent impacts on these nests will occur. The results of the survey, and any avoidance measures taken, shall be submitted to the City of Chino Hills 26 Vista Bella Townhomes (I I M 18698 and 08SPR01) December 23, 2009 P82 Community Development Department-Planning Division and the CDFG within thirty (30) days of completion of the pre-construction surveys and/or construction monitoring to document compliance with applicable state and federal laws pertaining to the protection of native birds, e. Less Than Significant with Mitigation Incorporated (Local Policies for Tree Preservation). Based on the General Plan policies and Development Code requirements described below, the following types of tress are present on the site which are subject to preservation: • Native Trees with a drunk diameter of four (4) inches or greater; • Eucalyptus (including windrows). Based on the "Tree Protection. Replacement and Mitigation Plan For: Vista Bella Townhomes which is consistent with the City's tree report guidelines, eighty-five (85) trees were identified on site and on the City owned parkway.

Development Code. Appendix B. Mandator/ Standards for All Areas • 5) Preservation of scattered mature specimen trees. Analysis The following is an excerpt from the "Tree Protection. Replacement and Mitigation Plan For Vista Bella Townhomes which summarizes the conclusions relative to the health of the trees and other reason why protection or relocation is not feasible: "General Conditions Affecting Tree Health The primary conditions affecting tree health are related to physical injuries, age, poor past pruning, lack of past pruning, crowding and past dryness. Several tree trunks have been injured by some past collision with farm tractors or other equipment. Many of the trees, especially the eucalyptus, have been headed, topped, or had inadequate training. As a result a higher rate of limb drop and decay can be expected. A number of large limbs have already failed. The previous redgum lerp psyllid infestation and past blue gum psyllid outbreak severely reduced their health. There are a number of dead stumps and some stumps have sprouted into many crowded trunks. While this is a large lot, many of the trees, especially the eucalyptus, have been planted so close together that their form is atypically narrow or they lean out for sun light. There is also a high level of competition in the eucalyptus windrow and other clusters of eucalypts. There are two species of eucalyptus on the site: the blue gums, Eucalyptus globulus, and manna gums, Eucalyptus viminalis. Both have a well-deserved reputation for structural failure. The blue gums have an equal risk of limb drop versus root failure and toppling. Lack of proper pruning and training has caused many structural defects that would be difficult to correct at this time. Once a tree has been topped the effects can be permanent. See State Government Code 53067. Due to lack of irrigation and drought 28 Vista Bella Townhomes (I I M 18698 and 08SPR01) December 23, 2009 P84 the tops of a number of eucalyptus have died, which also leads to excessively long limbs below, if the tree recovers. The southern California black walnut is a good tree for native wild life, but tends to have weak trunks and limbs, as well as being prone to decay. A few have fairly good form, but they are very sensitive to construction impacts and would be difficult to save. City Owned Trees in Right-of-Way Although the property is full of debris and trash, there is a well maintained parkway along Butterfield Ranch Road and a landscape planting at the corner of Butterfield Ranch Road and Saint Gaudens. It appears that the planting at the corner is on Vista Bella Property. The London plane trees in this planting are not very healthy, but could survive if irrigated and better maintained. The five trees in the City parkway are planned to be preserved, but the London Plane trees at the corner will be removed. Eucalyptus on Site There are 41 eucalypts on site over 4-inch trunk diameter. Nineteen of the 41 are blue gums and the rest are manna gums. All the manna gums on site and throughout southern California had been infested with redgum lerp psyllid (Glycaspis brimblecombei Homoptera: Psyllidae), and the Australian tortoise beetle, Trachymela sloanei, has infested manna gums and blue gums. Since 1999 the State released a parasite and the psyllid has been effectively controlled. Most of the eucalypts on site have been topped resulting in reduced health, reduced beauty, and increased hazard. Although there was a windrow along the southwest edge of the site, many have died and the rest are deformed. Although blue gum is a more typical windrow tree, on this site the windrow is entirely composed of manna gum. Some blue gums surround the old settling pond, but most are almost randomly scattered. A good number of large old stumps of blue gums remain. The smaller blue gums may be seedlings of them or the few large ones remaining. Many of the original eucalypts on this site have died and only stumps are remaining. This is probably due to the fact that over the past two decades two different eucalyptus longhorn borers have killed many of the drought stressed eucalyptus, especially blue gums, but more recently the State has released predatory wasps that parasitize the eggs of the borers. Unfortunately, the topping of eucalyptus is not uncommon. However, the resulting effects are well documented as being very destructive. In addition both blue gums and manna gums are well documented in the California Tree Failure Database, kept at U.C. Davis, as being prone to limb drop. With the species being hazardous and the past care making them more hazardous, these trees should not be over homes, streets and parking lots. Walnuts The existing walnuts in the study area are generally in poor structural condition. Some are in poor health, but my inspection being done in fall does not have foliage symptoms to consider. Decay is at a serious level in many specimens. Dieback, decay and cracks are common in many natural stands of California black walnuts. In addition they provide no function or purpose in the new intended use of the site and need more clearance relative to their size than more desirable species. Native walnuts are much more sensitive to construction impact (Matheny & Clark 1998). Compared to common 29 Vista Bella Townhomes (TTM 18698 and 08SPR01) December 23, 2009 P85 landscape trees, they are more prone to decay and limb breakage. The specimens on this site have some aesthetic value when viewed from a distance, but when viewed close up the decay, broken limbs and one-sided canopies distract from their appearance. If the City determines that it is critical to mitigate the loss of native walnuts on this site, it would be reasonable to plant new young trees on the small hill at the south corner of the property. California black walnuts are not always available. For the best availability, they should be ordered in December for delivery in spring or early summer. For good reasons the native southern California black walnut is almost never used for landscaping around homes or commercial buildings. In addition the specimens on site have not been trained or maintained to make them suitable for this use. Willows Arroyo willows are weak wooded like the walnuts. They are also pest and disease prone. Like the walnuts, they make a poor choice for landscape specimens. When either is grown, it is typically for revegetation of disturbed sites. Someone attempted to prune the willows in the north corner of the property, but they did a poor job and left the cut branches there on site. This pruning was poorly done and did not improve their structure. Since this species normally grows in wet areas, it is unusual to find them looking this healthy on an unirrigated and otherwise dry site. Health and Condition of Other Trees The only other species on site is one California pepper, Schinus molle. The California pepper is a nice young, low-branching specimen. The structure is fairly good, despite never being pruned or trained. This is not uncommon for young seedling pepper trees. However, decay and broken limbs are common in mature peppers. Grading will prevent leaving this tree fn place and it is not worth boxing only one tree. The unit cost would be higher than just buying a new one, which would also come with a guarantee, while the transplant would not." The health of the trees was confirmed by Bon Terra Consulting, the City's biological consultant. Based on the above, it does not appear feasible to preserve the trees on- site. In addition, there are several site constraints which limit the options for on-site tree preservation: • The location of the intersection of St. Gaudens Drive and Phidias Lane dictates where the primary access can be located. This fixed access point limits the site design options for building and driveway placement. • The parcel is irregularly shaped (narrower along the southern boundary and wider along the northern boundary). This also limits the site design options for building and driveway placement. • The adjacent topography along the western property boundary, particularly in relation to the knoll, would require extensive grading onto an adjacent property to allow more room on-site for more design flexibility. Although the site is designated as RM-2 which would allow up to 115 units (although such a yield is not realistic), the project is proposing 65 units. 30 Vista Bella Townhomes (TTM 18698 and 08SPR01) December 23, 2009 P86 Notwithstanding the tree health issues and site development constraints described above, the removal of the trees is considered to be a significant impact that will require mitigation. Table 9 provides a mitigation ratio for the removal of trees. Table 9. Tree Replacement/Mitigation Ratio Chart i F:'y "�?�?

CEQA Guidelines Section 15370 (e) describes "mitigation" in part as "compensating for the impact by replacing or providing substitute resources or environments". Therefore, Mitigation Measure BI0-3 would be considered adequate mitigation for the loss of trees. BIO-3: Prior to the issuance of a grading permit, the applicant shall pay cash in lieu in an amount to the City to provide for the planting of trees in City parks or City owned open space based on the mitigation ratio shown in Table 9 of the Initial Study. The cash in lieu amount shall be based on an industry standard used by City's Landscape Architect. The Community Development Director and Community Services Director or their designee may accept a combination of replacement trees and cash in lieu to satisfy this mitigation measure. f. No Impact (Conservation Plans). Development and operation of the Project is not expected to conflict with any adopted or approved habitat conservation plans because there are no conservation plans that incorporate the Project site. No mitigation measures are required. Checklist Item V. Cultural Resources a. No Impact (Historic Resources). Based on the Historical Resources Records Search: Vista Bella Townhomes by the Archaeological Information Center, San Bernardino County Museum, July 21, 2009 and a field inspection, there are no historic resources present on the Project site. No mitigation measures are required. b-c. Less Than Significant with Mitigation Incorporated (Archaeological/Paleontological Resources). According to the General Plan, the city contains numerous recorded paleontological and archaeological sites. The high potential for finding fossils and archaeological remains demands continual monitoring of new 31 Vista Bella Townhomes (TTM 18698 and 08SPR01) December 23, 2009 P87 development sites. (Reference, General Plan Page 4-8.) In addition, the Historical Resources Records Search: Vista Bella Townhomes by the Archaeological Information Center, San Bernardino County Museum, July 21, 2009 recommends monitoring during grading. Mitigation Measures CR-1 and CR-2 are recommended to mitigate impacts to less than significant: CR-1. A Paleontological Resource Impact Mitigation Program (PRIMP), shall be followed when construction excavation occurs within the project site, The PRIMP shall include the following steps: • A qualified paleontologist shall be present during ground disturbing activities within the project area. The paleontologist will be empowered to temporarily halt or redirect construction activities to ensure avoidance of adverse impacts to paleontological resources: The paleontologist will be equipped to rapidly remove any large fossil specimens encountered during excavation. During monitoring, samples will be collected and processed to recover microvertebrate fossils. Processing will include microscopic examination of the residual materials to identify small fossil remains. • Paleontological monitors shall work under the supervision of the principal paleontologist and shall maintain a daily log and map of specific locations monitored. • Monitors shall have the authority to divert grading to recover fossils. • An email detailing the evaluation shall be sent to the project proponent and the Community Development Director within 24 hours of discovery. • Significant fossils and paleontological resources, as determined by the principal paleontologist shall be curated at the Raymond Alf Museum. • The City of Chino Hills shall be considered the owner of all archaeological resources recovered. • A final monitoring compliance report detailing all results shall be submitted by the project proponent to the Community Development Director prior to the release or reduction of the grading bond. The final monitoring compliance report shall include Fowler accession number and a letter from the Museum stating that they are in possession of the artifacts. The project proponent is responsible for all costs associated with the Cultural Resources Mitigation Program including curation costs. CR-2. Monitoring by a qualified archaeologist meeting the Secretary of the Interior Professional Standards shall be required during all earthmoving, grading, grubbing, trenching or other earth-disturbing activities on the project site. A City-approved Project Archaeologist must create a Cultural Resources Mitigation Program mitigation-monitoring and disposition plan prior to 32 Vista Bella Townhomes (TTM 18698 and 08SPRO1) December 23, 2009 P88 earthmoving in the project area. The plan shall include the following provisions: • Monitoring and reporting shall be conducted by a qualified archaeologist. • Monitors shall maintain a daily log and map of specific locations monitored. • Monitors shall have the authority to divert grading to recover potentially significant resources. • Discoveries that meet the criteria significance under CEQA shall be marked off with lath and flagging and grading shall not occur within fifty (50) feet from the discovery perimeter until the find has been evaluated and a written release for grading is by the Building Official, as advised by the Archaeologist. For the purposes of CEQA, and "important archaeological resource" is one which: A. Is associated with an event or person of: 1. Recognized significance in California or American history, or 2. Recognized scientific importance in prehistory. B. Can provide information which is both of demonstrable public interest and useful in addressing scientifically consequential and reasonable or archaeological research questions; C. Has a special or particular quality such as oldest, best example, largest, or last surviving example of its kind; D. Is at least 100 years old and possesses substantial stratigraphic integrity; or E. Involves important research questions that historical research has shown can be answered only with archaeological methods. • Resources meeting the significance criteria of CEQA shall require testing and possible data recovery, identification of artifacts, analysis and a report. • An email detailing the evaluation shall be sent to the project proponent and the Community Development Director within 24 hours of discovery. • Except where archaeological resources are deemed to be owned by a recognized American tribe under Federal law, the City of Chino Hills shall be considered the owner of all archaeological resources recovered. • All resources meeting the significance criteria of CEQA shall be curated at the Fowler Museum of Cultural History at UCLA • A final monitoring compliance report detailing all results shall be submitted by the project proponent to the Community Development Director prior to the release or reduction of the grading bond. The final monitoring compliance report shall include Fowler accession number 33 Vista Bella Townhomes (TTM 18698 and 08SPR01) December 23, 2009 P89 and a letter from the Museum stating that they are in possession of the artifacts. The project proponent is responsible for all costs associated with the Cultural Resources Mitigation Program including curation costs. d. Less Than Significant (Disturbance of Human Remains). In the event of an accidental discovery or recognition of any human remains, California State Health and Safety Code Section 7050.5 dictates that no further disturbances shall occur until the County Coroner has made the necessary findings as to origin and disposition pursuant to CEQA regulations and PRC Section 5097.98. This is a mandatory requirement that will be included in the Project's Conditions of Approval. No mitigation measures is required. Checklist Item VI. Geology and Soils The following analysis is based on the Supplemental Geotechnical /nvesfioation and Response to Geotechnical Review Sheet Proposed Butterfield Ranch Road Townhomes by Southern California Geotechnical, April 4, 2008. a. Less Than Significant Impact (i-iv, Alquist-Priolo Zone, Seismic Ground Shaking, Seismic Ground Failure (Liquefaction) or Landslide). i) Alquist-Priolo Zone: The Project site is not located within an identified Alquist-Priolo Earthquake Hazard Zone. Therefore, impacts are considered less than significant. No mitigation measures are required. ii) Seismic Ground Shaking: Seismic ground shaking is influenced by the proximity of the site to an earthquake fault, the intensity of the seismic event, and the underlying soil composition. The site will be subject to strong ground motions during a seismic event on the Chino-Central Avenue Fault which is located 1,000 +/- feet west of the site. Compliance with the City's adopted building code, and conformance with Project geotechnical recommendations will ensure that impacts associated with seismic events would remain less than significant. No mitigation measures are required. The fact that an earthquake occurred in the Chino Hills area in 2008 does not affect this analysis, but instead only reinforces the conclusions regarding seismic hazards. iii) Seismic Ground Failure (Liquefaction): The liquefaction analysis indicates that none of the encountered soil strata are subject to liquefaction during the design seismic event. All of the soils encountered below a depth of 17+ feet possess factors of safety against liquefaction, consist of non-liquefiable clays, or non-liquefiable bedrock. Impacts from liquefaction are less than significant. No mitigation measures are required. iv) Landslide: The site is not located within a designated area where previous occurrence of landslide movement, or local topographic, geological, geotechnical and subsurface water conditions indicate a potential for landslides. Impacts from landslides are less than significant. No mitigation measures are required. 34 Vista Bella Townhomes (I I M 18698 and 08SPRO1) December 23. 2009 P90 b. Less than Significant Impact (Soil Erosion, Loss of Top Soil). Development of the site will require grading which will result in the loss of topsoil and the potential for soil erosion. However, the loss of topsoil is not considered a significant impact because the site is not being used for agricultural purposes and is designated for residential development by the City of Chino Hills General Plan. Construction activity associated with Project development may result in wind and water driven erosion of soils due to grading activities if soil is stockpiled or exposed. The applicant will be required to adhere to conditions under the National Pollutant Discharge Elimination System (NPDES) Permit issued by the Regional Water Quality Control Board (RWQCB) and prepare and submit a Storm Water Pollution Prevention Plan (SWPPP) to be administered throughout Project construction. The SWPPP will incorporate Best Management Practices (BMPs) to ensure that potential water quality impacts during construction from water erosion would be reduced to less than significant. In addition, the applicant would be required to adhere to SCAQMD Rule 403—Fugitive Dust, which would further reduce the impacts associated with wind erosion. Therefore, impacts would be less than significant. Previously undisturbed soil will be replaced with structures, pavement and landscaping as part of the residential development, which will reduce the amount of soil erosion. Therefore, impacts would be less than significant. No mitigation measures are required. c. Less Than Significant Impact (Unstable Geologic Unit), The soil and bedrock materials which comprise the subject site are not expected to be subject to any significant ground lurching or lateral spreading. Also see discussion in Checklist Item Via above. No mitigation measures are required. d. Less Than Significant Impact (Expansive Soil). The on-site soils are not considered to be subject to significant seismically-induced settlements, The soil materials which underlie the project site consist primarily of dense sandstone bedrock or older alluvium. With adherence to mandatory City grading requirements impacts will be less than significant. No mitigation measures are required. a No Impact (Septic Tank Suitability). The project will be required to have a private on-site sewer that will connect to the City sewer system. No mitigation is required. Checklist Item VII. Hazards and Hazardous Materials. a. Less than Significant Impact (Transport, Use, or Disposal of Hazardous Materials). This residential land use is not associated with the routine handling of hazardous materials and the generation of large quantities of hazardous wastes. During construction, there will be ordinary quantities of building and paving materials, including hazardous materials and wastes that will be handled under Best Management Practices under the National Pollution Discharge Elimination System requirements. Upon occupancy of the Project, site maintenance and landscaping will require ordinary types of hazardous materials such as pesticides and herbicides, but none of these will be used or stored on site in large quantities. No mitigation measures are required. b. Less Than Significant Impact (Upset and Accident Conditions Involving Hazardous Materials) As indicated in Checklist Item Vila above, the residential nature of the Project will not involve the substantial use of hazardous materials. No mitigation measures are required. 35 Vista Bella Townhomes (I I M 18698 and 08SPRO1) December 23, 2009 P91 c. Less Than Significant Impact (Emit of Handle Hazardous Materials within 114th of a Mile from a School) The project site is located within 1/4I" of a mile of Chino Hills High School. However, as indicated in Checklist Item Vila above, the residential nature of the project will not involve the substantial use of hazardous materials, No mitigation measures are required. d. No Impact (Identified Hazardous Site). According to California Department of Toxic Substance Control, the Project site is not listed as a hazardous materials site (Cortese List). No mitigation measures are required. e. No Impact (Within Airport Plan Area). According to the Comprehensive Land Use Plan, Chino Airport, the site is not located within the Airport Referral Areas (i.e. a designated area consisting of various noise, safety, and height restrictions). No mitigation measures are required. f. No Impact(Safety Hazard from Private Airstrip). The site is not located within the vicinity of a private airstrip. No mitigation measures are required. g. No Impact (Impair Emergency Evacuation Plan). Establishment and operation of the Project will not impair or physically interfere with emergency responses or evacuation. Two points of access, as required by the Chino Valley Independent Fire District are provided by the project. Butterfield Ranch Road and St. Guadens Drive will not be altered by the project causing interference with emergency evacuation plans, No mitigation measures are required. h. No Impact (Wildland Fires Hazard). The site is surrounded by urban development on all sides. In addition, according to the City of Chino Hills Fire Hazard Overlay District Map dated May 11, 2005, the Project site is not located in a Fire Hazard District. No mitigation measures are required. Checklist Item VIII. Hydrology and Water Quality, a. Less Than Significant Impact with Mitigation Incorporated(Water Quality, Waste Discharge). The Project has the potential to discharge pollutants that may impact water quality. The on-site storm drain system will be designed to comply with the National Pollutant Discharge Elimination System (NPDES) standards to ensure that pollutants are not discharged into the storm drain system. The NPDES requires "Best Management Practices" (BMPs) for Site Design, Source Control, and Treatment of pollutants. Mitigation Measure HYD-01 is recommended to reduce impacts to less than significant. HYD-1. Prior to the issuance of building permits, a final WQMP will be submitted by the applicant and approved by the City's Engineering Department, and strict adherence to the program will be required. b. Less Than Significant Impact (Groundwater). Based on the Supplemental Geotechnical lnvestioation prepared for the project groundwater was encountered at a depth of forty-six (46) feet. Development of the site is not anticipated to interfere with groundwater supplies because site grading will not reach that depth. In addition, the site is not being used for aquifer recharging and adequate water supplies exist to serve the 36 Vista Bella Townhomes (TTM 18698 and 08SPR01) December 23, 2009 P92 Project. (See discussion in XVI). Impacts are less than significant. No mitigation measures are required. a, Less Than Significant Impact with Mitigation Incorporated(Drainage Patterns). Development of the Project site will create impervious surfaces and increase the amount of surface runoff. This could be considered a significant impact. According to the Hydrology Report for Vista Bella Townhomes prepared by Coory Engineering, the Project receives drainage from approximately 5.20 acres of land lying to the southwest which produce Q100 flows of 33.5 cfs and Q10 flows of 21.2 cfs. These flows will be intercepted at the southerly property line and conveyed via concrete swales and/or 18- inch pipes to a new 24-inch storm drain which will run northerly within the new project access road to a connection with an existing 36-inch storm drain lying within Butterfield Ranch Road that currently connects to an existing 60-inch culvert which crosses under Butterfield Ranch Road. The existing 60-inch culvert can handle Q100 flows of 216.3 cfs. The 60-inch culvert conveys drainage northerly into the Lower Los Serranos Channel near Highway 71. An on-site detention basin with a drain line connected to the existing 60" culvert will be sized to control the flow rate of on-site runoff so as not to exceed the pre-development condition. Mitigation Measure HYD-2 is recommended to reduce impacts to less than significant. HYD-2. Prior to the issuance of a building permit, a drainage plan shall be submitted that provides for a concrete box with a volume of 8,000 fta shall be required to serve as an underground detention basin and will be located at the lowest reach of the storm drain system. Prior to discharging the on-site runoff from the detention basin into the existing 60" storm culvert, a pipe outlet will be sized such that the post development peak flows from a 10 year storm as calculated by the rational method do not exceeded the pre-development peak flows of 8.94 cfs. d. Less Than Significant Impact with Mitigation Incorporated (Flooding) See the above-discussion on Checklist Item Vlllc. e. Less than Significant Impact with Mitigation Incorporated (Storm Drains). See the above-discussion on Checklist Items VIII (a) and (c). f. Less than Significant Impact with Mitigation Incorporated(Water Quality). See the above-discussion on Checklist Item VIII (a) and (c). g. No Impact (Housing in 100- Year Flood Hazard Area). According to the National Flood Insurance Program (FIRM 2008), the site is located in Zone "X" as shown on Map Index Community-Panel No. 06071C9330F, Map Revised, March 18, 1996. Based on information contained in TTM 18698 there will be no impacts from 100 year-flood events, No mitigation measures are required. h. No Impact (Redirect Flood Flows). The Project would not impede or redirect flood flows. See the above-discussion on Checklist Item VIII (d). i. No Impact (Flood Levee or Dam). The Project is not located in an area that is subject to hazards from dam failure according to Figure S-6 of the General Plan. No mitigation measures are required. 37 Vista Bella Townhomes (TIM 18698 and D8SPRO1) December 23, 2009 P93 j. No Impact (Seiche, Tsunami, or Mudflow). Seiches, tsunamis, and mudflows are associated with large bodies of water. No body of water large enough to create a seische, tsunami, or mudflow is located in the proximity of the Project. No mitigation measures are required. Checklist Item IX. Land Use and Planning a. No Impact (Physical Division, Land Use Plans). The Project will not physically divide an established community. The site is adjacent to two roadways (Butterfield Ranch Road and St. Gaudens Drive) and is surrounded by existing development on all sides. No mitigation is required. b. No Impact (Land Use Plans). The Project is designated by the General Plan as High Density Residential and has a Zoning classification of High Density Residential (RM- 2) which allows for residential development at a maximum of 25 dwelling units per acre. The project is proposed at a density of 14 dwelling units per acre, therefore, it is not in conflict with the General Plan. No mitigation measures are required. c. No Impact (Conservation Plans). The Project site is not located within an established conservation. No mitigation measures are required. Checklist Item X. Mineral Resources. a. No Impact (Loss of Mineral Resources). According to maps prepared by the California Geological Survey (CGS 2008) the site is not identified as having a known mineral resource. The resource most likely to occur in the region is aggregate used for construction purposes, According to the CGS, the site is located within the Claremont- Upland Region for aggregate production. Currently there are several sites within the region that are producing between 0.5 to 10 millions tons per year of aggregate, Given the site's location in a residential area, it is not a candidate site for aggregate production. No mitigation measures are required. b. No Impact(Site Delineated as Mineral Resource Site). The site is not designated as a mineral recovery site by the General Plan Land Use Map. No mitigation measures are required. Checklist Item Xl. Noise. a. Less Than Significant with Mitigation Incorporated (Exceed Noise Standards). Short-Term Construction Noise Impacts The City's threshold of significance for noise impacts is sound levels that reach 65 dBA for exterior and 45 dBA for interior locations for residential development, Construction noise could exceed these levels adjacent to the site during construction. Per the City of Chino Hills Noise Ordinance Municipal Code Section 8.08.020, construction activity is limited to daytime hours between 7:00 a.m.and 7:00 p.m. on weekdays, and between 8:00 a.m. and 6:00 p.m, on Saturdays, and prohibited on Sundays and federal holidays. Because of the short duration of the construction noise and the fact the project has to comply with mandatory requirements in the City's Noise Ordinance. In order to reduce 38 Vista Bella Townhomes (TTM 18698 and 08SPR01) December 23, 2009 P94 noise form construction on adjacent residents. Mitigation Measure NOI-1 is recommended, NOI-1. All construction equipment shall utilize noise reduction features (e.g., mufflers and engine shrouds) that are no less effective than those originally installed by the manufacturer. Exterior Noise Impacts The long-term on-going operation of the proposed project would result in an increase in noise levels as a result of an increase in vehicle traffic. Based on the Acoustical Analysis Vista Bella Townhouse. City of Chino Hills, by Gordon Bricken & Associates. November 2, 2007, traffic noise is projected to be 72 dBA CNEL at 50 feet from the centerline of Butterfield Ranch Road. This would exceed the City standard of 65 dBA for exterior noise levels. The following mitigation measure is proposed to reduce impacts to less than significant: NOI-2: Sound walls at least five (5) feet high shall be constructed around the exposed perimeters of all first floor private patios facing Butterfield Ranch Road. Prior to the issuance of building permits, the design of the sound walls shall be approved by the Community Development Department. Prior to the issuance of an occupancy permit, the completed sound walls shall be reviewed for approval by the Community Development Department. Interior Noise Impacts The Acoustical Analysis shows that the exterior noise levels at the building facade will range from 45 to 69 dBA CNEL. This would exceed the City standard of 45 dBA CNEL in most cases. In order to reduce this impact to less than significant levels, the following mitigation measure is proposed: NOI-3: All buildings shall be constructed with the following noise attenuation features: Panel I Construction Exterior Wall *Siding or stucco, 2" x 4" studs, R-13 fiberglass insulation, 1/3" drywall Windows Double pane Sliding Glass Door Double pane Roof Ii Tile over 1/2" plywood, fiberglass I insulation, 518" drywall, vented Floor j Carpeted except kitchen and baths C "Add STC 28 glazing to all rooms with any view of Butterfield Ranch Road. b. Less than Significant Impact with Mitigation Incorporated (Groundborne Vibration). The closest potentially impacted receptors from groundborne vibration noise (primarily from the use of heavy construction equipment) on nearby land uses are the single-family homes and apartment homes located adjacent to the site. Impacts on these 39 Vista Bella Townhomes (I I M 18698 and 08SPR01) December 23, 2009 P95 residential uses could be signification. Mitigation Measure NOI-3 is recommended to reduce impacts to less than significant. NOI-4. Vibratory rollers shall not be used within 26 feet of any structure or property boundary of the adjacent residential development during any phase of construction In order to prevent construction vibration levels from reaching above 0.2 PPV, the City of Chino Hills vibration standard. Bulldozers (such as a Caterpillar D8), or other alternate equipment shall be used for grading, which have vibration levels below that of vibratory rollers. Additionally, where feasible, a trench (approximately 5-foot wide by 10 to 15 feet deep) shall be dug around the perimeter of the area to be graded to further reduce vibration to the residents. c. Less Than Significant Impact (Ambient Noise Levels). The City's threshold of significance for noise impacts is sound levels that reach 65 dBA for exterior and 45 dBA for interior locations for residential development. A significant impact would result if the project increased noise levels by 3dBA or if it increases the existing noise levels above 65dBA. Based on noise measurements contained in the Noise Impact Analysis, noise in the project area is characterized by vehicle traffic as well as aircraft noise landing and taking off from Chino Airport. The Noise Impact Analysis found that the ambient noise level in the Project area ranged from 51.0 dBA to 59.7 dBA. The Noise Impact Analysis determined that the increased traffic from the project would increase the ambient noise levels by a maximum of 0.6 dBA which is less than the 3dBA increase threshold for determining significance. No mitigation measures are required. d. Less Than Significant Impact (Temporary Noise Levels). Implementation of the proposed project will result in an increase in noise levels, associated with construction activities. Construction of the project will result in a minor, temporary increase in noise levels, and per the City of Chino Hills Noise Ordinance Municipal Code Section 8.08.020, construction activities are limited to daytime hours between 7:00 a.m. and 7:00 p.m. on weekdays, and between 8:00 a.m. and 6:00 p.m. on Saturdays and is prohibited on Sundays and federal holidays. Compliance with the Noise Ordinance is a mandatory requirement. No mitigation measures are required. e. No Impact (Airport Noise). According to the Comprehensive Land Use Plan, Chino Airport, the site is not located within the Airport Referral Areas (i.e. a designated area consisting of various noise, safety, and height restrictions). No mitigation measures are required. f. No Impact(Private Airstrip). The Project site is not located near a private airstrip. Checklist Item XII. Population and Housing. a. Less than Significant Impact (Population Growth). The Project is a multiple-family residential development, with 65 units. Based California Department of Finance data (DOF 2008), there are 3.3 persons per household in the City. This results in a population increase of 214 persons. Although the Project will induce population growth, the growth is not above General Plan buildout projections because the Project does not exceed the General Plan density of 25 dwelling units per acre. No mitigation measures are required. b. No Impact(Displace Housing). The Project is to be constructed on a vacant site and it will not displace any housing, It will provide new housing for households of various sizes. No mitigation measures are required. 40 Vista Bella Townhomes(TTM 18698 and 08SPR01) December 23, 2009 P96 Checklist Item XIII. Public Services. a. Less Than Significant Impact (Fire Services). The Chino Valley Independent Fire District maintains Station No. 62 at 5551 Butterfield Ranch Road which serves the Project site. Currently, the station houses a Paramedic Engine Company staffed with four personnel. Development fees are collected for the provision of capital facilities for fire services. No mitigation measures are required. b. Less Than Significant Impact (Police Services). The Chino Hills Police Department can adequately respond to calls for service and to periodically monitor the Project site. Development fees are collected for the provision of capital facilities for police services. No mitigation measures are required. c, Less Than Significant Impact(Schools). The Project will add additional students to the Chino Valley Unified School District (CVUSD). The project area is served by the following schools; Chino Valley High; Townsend Jr. High; and Wickman Elementary, In the past, CVUSD has indicated that additional students can be accommodated but cannot guarantee that students will attend schools within their attendance area. Under state law, impacts on schools is considered to be mitigated under the California Environmental Quality Act through payment of mandatory school impact fees. The Project is required to pay the state mandated school impact fees, therefore, no mitigation measures are required. d, Less Than Significant Impact(Parks). The nearest park in the vicinity of the Project site is Alterra Park. The City requires the payment of mandatory park fees to continue to provide park and recreation facilities as population increases. No mitigation measures are required. e. Less Than Significant Impact (Other Public Facilities). The public improvements associated with development of the Project are minimal as streets and nearby backbone infrastructure is already in place. The project will not require the major extension or expansion of public facilities as it is an infill site surrounded by urban development. No additional public facilities are needed to be constructed to accommodate the project other than connection to the existing facilities. No mitigation is required. Checklist Item XIV. Recreation a-b. Less than Significant Impact (Existing Facilities, New or Altered Facilities). The Project will add approximately 214 persons to the City's population and some may include existing residents. The Project of and by itself does not result in the need for new recreational facilities, but will be required to pay the mandatory park fee for future facilities. See discussion in Section Xllld above. Checklist Item XV. Transportation/Traffic. a-b. Less Than Significant Impact (Roadway Capacity, Level of Service, Congestion Management Program). Based on the Vista Bella Condominiums/Townhomes Traffic Impact Assessment Letter prepared by AAE, Incorporated, dated December 14, 2009, the Project is projected to generate 44 trips in the AM Peak Hour and 48 trips in the PM Peak Hour, Because the number of trips is 41 Vista Bella Townhomes (I I M 18698 and 08SPR01) December 23, 2009 P97 below the City's threshold of 50 peak hour trips, the City Traffic Engineer has determined that the project will not have a significant impact on the surrounding roadways and intersections. No mitigation is required. c. No Impact(Air Traffic Patterns). The site is located approximately 2 plus miles west of the Chino Airport. According to the Chino Airport Master Plan, the site is not located in any airport hazard zones related to air traffic patterns. d. No Impacts (Roadway Design Hazards). The project site driveways are to be built in accordance with the City's design standards, subject to review and approval of the City Engineer and the Fire District. Thus, no dangerous design features or hazards will be created. e. No Impact (Emergency Access). All portions of the project site will be easily accessible to emergency vehicles by paved roadways and interior access driveways. f. Less Than Significant Impact(Parking). 163 parking spaces are required and the Project provides 164 on-site parking spaces, with two covered spaces within garages for each unit, as well as .5 spaces per unit for guest parking, as required by the City Development Code, 2 additional spaces are provided and designated for mail delivery and pick-up, as well as 3 designated spaces for accessible parking. The proposed parking scheme meets all the Development Code standards as well as ADA requirements. No mitigation measures are required. g. No Impact(Alternative Transportation). Development of the Project does not conflict with any policies, plans, or programs that support use of alternative transportation. Checklist Item XVI. Utilities and Service Systems. a. Less Than Significant Impact(RWQCB Wastewater Treatment). The City is required to adhere to the requirements of the Regional Wastewater Ordinance established by the Inland Empire Utilities Agency which requires Pre-Treatment regulations to prevent the introduction of pollutants into the regional sewerage system. No mitigation is required other than mandatory compliance with the Regional Wastewater Ordinance. b. Less Than Significant Impact (New Water and Wastewater Facilities). The Project will not increase the demand for additional water supplies to the extent that new facilities will be required (See Checklist Item XVId-e below). No mitigation measures are required. c. Less Than Significant Impact (New Storm-Water Drainage Facilities). Development of the Project site will create impervious surfaces and increase the amount of surface runoff. Based on the Hvdroloov Report for Vista Bella Townhomes orepared by Coory Engineering, the Project receives drainage from approximately 5.20 acres of land lying to the southwest which produce Q100 flows of 33.5 cfs and Q10 flows of 21.2 cfs. These flows will be intercepted at the southerly property line and conveyed via concrete swales and/or 1S-inch pipes to a new 24-inch storm drain which will run northerly within the new project access road to a connection with an existing 36-inch storm drain lying within Butterfield Ranch Road that currently connects to an existing 60-inch culvert which crosses under Butterfield Ranch Road. The existing 60-inch culvert can handle Q100 flows of 216.3 cfs. The 60-inch culvert conveys drainage northerly into the Lower Los Serranos Channel near Highway 71. An on-site detention basin with a drain line 42 Vista Bella Townhomes (TTM 18698 and 08SPR01) December 23, 2009 P98 connected to the existing 60" culvert will be sized to control the flow rate of on-site runoff so as not to exceed the pre-development condition. No mitigation measures are required. d. Less Than Significant Impact (Water Supplies). The City's water supply is provided from various sources including the Water Facilities Authority, Monte Vista Water District, Chino Desalter Authority as well as groundwater production from within the Chino Groundwater Basin. The 2005 City of Chino Hills Water. Recycled Water and Wastewater Master Plan (Master Plan) evaluated the City's existing and planned water sources, and water distribution systems with their respect to their ability to meet projected demands. The Master Plan considered the City of Chino Hills General Plan Land Use Plan in determining future water demand. The evaluation of water demands includes a comprehensive assessment of historical demands and a projection of future demands based on forecasted development of the remaining developable lands within the City's water service area. Projections were done in 5-year increments, as estimated from the status and timing of currently approved development as well as probable future development within the context of the City's General Plan. The existing demands are based on actual observed water use, with future demands estimated from reasonable demand coefficients applied to various categories of land use. The General Plan Land Use designation for the property is High Density Residential with a density of up to 25 dwelling units per acre. Under the General Plan, the site (4.62 acres) has the potential to develop 115 units. The Master Plan projected water demand for the site was for 115 units. The project is proposing 65 units, which is well below the demand projected. The demands were derived from observed water use during one of the driest prolonged periods on record (2002), and they are believed to be representative of a "worst case" water demand environment. The maximum daily demand water supply capacity requirement for 2010 is 29.10 million gallons per day (MGD), whereas the capacity available is 41.14 MGD. For 2020, a forecasted 31.25 MGD is required with 48.94 MGD available. At ultimate buildout 2025, the capacity requirement will be 32.86 MGD with 48.94 MGD available. Based on the aforementioned information, the City, with its present and "imminent" mix of water sources, possesses a significant surplus of capacity. According to Section 3.6 Adjusted Source Capacity Surplus (page 3-18) of the Master Plan, a shortage scenario wherein the City's well capacity was reduced by 50 percent and imported water deliveries were restricted to 80 percent of nominal maximum deliveries, the City would still have 5 MGD of capacity over and above its ultimate maximum day requirements. Therefore, sufficient water supply is available for the development. No mitigation measures are required. a Less Than Significant Impact (Wastewater). Based on IEUA generation factors for wastewater, the Project is projected to generate 17,550 gallons per day of wastewater per equivalent dwelling unit (270 gallons x 65 units = 17,550 gallons). The IEUA maintains a Wastewater Facilities Master Plan (WFMP). Some of the objectives of the 2002 WFMP were to: (1) identify facilities that need to be replaced or expanded in the near- and long- term to meet projected growth and wastewater flow needs; (2) develop a cost-effective, phased implementation plan; (3) determine space and location needs for additional or expanded treatment facilities; (4) develop strategies for flow diversion between service areas to optimize existing treatment capacity utilization; and (5) maximize water recycling, energy efficiency, and organics recycling. Treatment capacity expansions will be needed to accommodate the forecasted future flows for growth in the service area of Regional Plant (RP) 5 which serves the Project area. The WFMP included plans for expansion of wastewater facilities to meet the needs of growth within the service area through 2050. Specifically, it included improvements and expansion of wastewater facilities at RP-4; construction of a new 15-MGD wastewater facility at RP-5; conversion of RP-2 to a solids 43 Vista Bella Townhomes (TTM 18698 and 08SPRO1) December 23, 2009 P99 handling facility only (elimination of wastewater treatment at RP-4); and numerous upgrades and odor control facilities at RP-1 and Carbon Canyon RWRF. These plans have all been implemented. No mitigation is required. f. Less Than Significant Impact (Landfill). Solid waste generated by the Project would most likely be transported to the El Sobrante Landfill. According to the California Integrated Waste Management Board, the El Sobrante Landfill has adequate capacity to handle solid waste in the region until 2030. In addition, the project will be conditioned to comply with the City's solid waste and recycling program. No mitigation is required, g. Less Than Significant Impact (Solid Waste). The City participates in mandatory source reduction and recycling efforts administered by the California Integrated Waste Management Board, In addition, City Municipal Code Chapter 13.20 "Integrated Waste Management Systems" requires compliance with solid waste disposal requirements. These are mandatory requirements, no mitigation is required. Checklist Item XVII. Mandatory Findings of Significance a. Less Than Significant Impact with Mitigation Incorporated(Environment and Habitat). Based on the analysis contained in this Initial Study, impacts to Aesthetics, Agriculture Resources, Air Quality, Geology/Soils, Hydrology/Water Quality, Land Use and Planning, Mineral Resources, Population/ Housing, Public Services, Recreation Transportation/Traffic, and Utility/Services Systems would have a less than significant on the environment. Impacts to Biological Resources (California Black walnut, wetlands, nesting birds) would be significant unless mitigated. Mitigation Measures, BIO-1 through BIO-3 are required of the Project. Impacts to Cultural Resources (archaeological and paleontological) would be significant unless mitigated. Mitigation Measures CR-1 and CR-2 are required of the Project. Impacts from Noise would be significant unless mitigated. Impacts to Hydrology and Water Quality would be significant unless mitigated. Mitigation Measures HYD-1 and HYD-2 are required of the Project. Mitigation Measures Mitigation Measures NOI-1 and NOI-2 are required of the Project. The implementation of the Mitigation Measures identified above would result in less than significant impacts to Biological, Cultural Resources, Hydrology and Water Quality, and Noise. Therefore the Project will not degrade the quality of the environment and no habitat, wildlife populations, and plant and animal communities would be impacted. b. Less Than Significant Impact (Cumulatively Considerable). Based on the analysis contained in this Initial Study, the Project's land uses are consistent with the City's General Plan land use projections. These land uses have been considered with overall City growth (including increases in traffic, noise, changes to air quality etc.) In addition, the Project would not produce impacts, that considered with the effects of other past, present, and probable future projects, would be cumulatively considerable because any significant impacts as a result of the Project are reduced to less than significant levels. c. Less Than Significant Impact (Human Beings). The implementation of the Mitigation Measures identified in this Initial Study and compliance with mandatory City requirements would result in less than significant impacts to human beings, either directly or indirectly. 44 Vista Bella Townhomes (TTM 18698 and 08SPRO1) December 23, 2009 P100 8.
