A Storm Water Pollution Prevention Plan (SWPPP) shall be PAGE NO. 19 RESOLUTION NO. 93-34 10. 11. 12. 13. 14. 15. 16. 17. prepared as part of the preparation of project improvement plans to assure prevention of construction related silt and pollutants from leaving the site and polluting the downstream water courses. The SWPPP shall supplement the eros/on control plan prepared for the project. Ifa common carwash area is created to serve the project, the waste water created by washing cars shall be directed to the sewer collection system rather than the storm water collection system, unless otherwise authorized by the SWPPP. Off-site drainage flows shall be intercepted at the project boundary via an approved storm drain facility, or as approved by the Town. Roof drainage shall be collected and conveyed by pipe (i.e., shall not be emptied onto paved areas, concrete swales, other similar surface grade dissipating devices). All site drainage shall be conveyed directly to the project's storm drainage system. Concentrated drainage flows shall not be permitted to cross sidewalks or driveways. Any portion of the drainage system that conveys runoff from public streets shall be installed within a dedicated drainage easement, or public street. If a storm drain must cross a lot, or be in an easement between lots, the easement shall be equal to or at least double the depth of the storm drain. The developer shall furnish proof to the City Engineer of the acquisition of all necessary rights of entry, permits and/or easements for the construction of off-site temporary or permanent road and drainage improvements. Electrical, gas, telephone, and Cable TV services, shall be provided underground in accordance with the Town policies and existing ordinances. All utilities shall be located and provided within public utility easements, sited to meet utility company standards, or in public streets. All new utilities required to serve the development shall be installed underground. Existing above-grade utilities on the Hartz Way frontage of the subject property shall be relocated as required by the project, but are not required to be placed underground. PAGE NO. 20 RESOLUTION NO. 93-34 * 18. All public improvement plans shall be prepared by a licensed civil engineer. 19. The developer shall mitigate the impact of additional stormwater runoff from this development on the San Ramon Creek watershed by either of the following methods: Removing one cubic yard of channel excavation material from the inadequate portion of San Ramon Creek near Chaney Road for each 50 square feet of new impervious surface area created by the development. All excavated material shall be disposed of offsite by the developer at his cost. The site selection, land rights, and construction staking will be by the Contra Costa County Flood Control & Water Conservation District. OR, AT THE OPTION OF THE DEVELOPER, bo Provide a cash payment in lieu of actual excavation and removal of material from the inadequate portion of San Ramon Creek near Chaney Road. The cash payment will be calculated at a rate of $0.10 per square foot of new impervious surface area created by the development. The added impervious surface area created by the development will be based on the Contra Costa County Flood Control & Water Conservation District's standard impervious surface area ordinance. 20. Any on-site wells and septic systems shall be destroyed in accordance with Contra Costa County Health Services Department - Environmental Health Division regulations. Environmental Health Division permit and inspections for this work shall be obtained. 21. The Contra Costa County Flood Control & Water Conservation District (CCCFC & WCD) shall be granted an easement across the subject property to provide access from Hartz Way through the project to access the existing CCCFC & WCD easement which used to outlet onto Hartz Court. The easement shall have a minimum width of fourteen feet and any curves must have at least a forty foot outside turning radius to guarantee CCCFC & WCD maintenance vehicle access. The developer shall prepare a legal description and plat map for the easement and make an offer of dedication to CCCFC & WCD once the documents are approved by the CCCFC & WCD. PAGE NO. 21 RESOLUTION NO. 93-34 I 22. Prior to the recordation of the initial final map for the project, documentation shall be submitted that the northern portion of the subject property has been deeded by grant deed transfer to the Contra Costa County Flood Control & Water Conservation District as called for by Minor Subdivision MS 855-91 (must include the improved section of San Ramon Creek and at least twenty-one feet of flat, unobstructed area between the existing creek top of bank and the south boundary of the area of dedication for use as an access road). 23. The submittal for final development plan and tentative map applications shall include typical preliminary drainage plans for individual private yard areas (plans shall detail the area drains to be provided in a typical five-unit motor court pod). MISCELLANEOUS Minor modifications to the Preliminary Development Plan - Rezoning may be considered and approved through the Planning Commission review of the project final development plan/tentative map application submittal. Conditions of this approval may require the applicant to install public improvements on land neither the applicant, not the Town, has easement rights to allow the improvements to be installed. The applicant shall be responsible for acquisition of the necessary easements either through private negotiations or by entering into an agreement with the town and assume all responsibilities for acquisition pursuant to the Town's authority for condemnation. Such acquisitions shall be commenced prior to the applicant's submittal of any final map. All costs associated with such acquisition shall be borne by the applicant. ° To mitigate existing and future outdoor noise impacts to the planned residential units in this project (and consistent with the findings and recommendations of the project-specific noise study and the previously prepared noise study for the 1-680 freeway widening project), the project sponsors shall be responsible for the establishment of a noise attenuation system which provides noise mitigation of existing and future freeway noise at the levels indicated in Table 3 of the August 6, 1993 Salter noise study (attenuation secured from use of a twelve foot high sound wall). Ifa sound wall is ultimately selected as the noise attenuation system for the project, the sound wall shall be constructed with a height in the eleven PAGE NO. 22 RESOLUTION NO. 93-34 ,5. to twelve foot height range (as measured from the freeway hinge point) and shall extend a minimum of lOO feet north of the north side of the 1- 680 crossing of San Ramon Creek, unless otherwise authorized based on subsequent acoustical analysis, preparation of detailed project grading plans and preparation of detailed sound wall construction plans. The precise design and location of the noise attenuation system utilized shall be subject to review and approval of the Town of Danville and Caltrans (as applicable) prior to installation. The noise attenuation system utilized shall be installed prior to occupancy of any units in the project. To mitigate existing and future indoor noise impacts to the planned residential units in this project (and consistent with the findings and recommendations of the project-specific noise study and the previously prepared noise study for the 1-680 freeway widening project), the project sponsors shall be responsible for assuring installation of sound-rated windows for all building facades that are exposed to a existing or future CNEL above 60 dB. Sound-rated windows utilized shall yield indoor noise levels of CNEL 4_5 dB for existing and projected noise levels. Ail units necessitating use of sound-rated windows shall be designed with an alternate method of supplying fresh air (e.g., mechanical ventilation)for the rooms that require use of sound-rated windows. Ail development shall be subject to the requirements of the San Ramon Valley Fire Protection District. As development occurs, the developer shall pay impact and capacity fees for the above services as required by the respective districts. Use of a private gated entrance is expressly prohibited. If, at some future date use of a gated entry system is desired, its installation shall not occur until a revised final development plan is secured detailing the precise design and location of the system. The project homeowners' association, through project-specific covenants, conditions and restrictions (CC&Rs), shall be responsible for maintenance of all on-site roads, pedestrian ways, common landscape areas, common fencing, the project recreation areas, internal roads and motor court and parking areas, non-structural maintenance/upkeep of the existing retaining wall along the subject property's eastern boundary, common drainage facilities, and any project installed landscaping authorized to be installed in PAGE NO. 23 RESOLUTION NO. 93-34 the adjoining section of the 1-680 right-of-way. The project CC&Rs shall be submitted to the Town of Danville for review and approval a minimum of 30 days prior to recordation of the final map. The CC&Rs shall reference the approved residential design guidelines (see Conditions # B-3) and the measures to assure protection of on-site trees to be preserved (see Condition #C-6). The locations where trash and recycling containers are placed by individual residents for weekly pick-up are subject to review and approval by the Town of Danville and the local disposal agency. If it is determined by these agencies that constraints are present, due to the dimensions of the individual motor courts, which result in unsafe and/or inefficient trash and/or recyclable pick-up, the applicant shall be responsible for the establishment of common enclosure areas for trash and/or recyclable pick- ups. The CC&R's shall establish resident requirements for the storage of trash and recycling containers and shall outline the requirements for the placement and retrieval of said containers for weekly pick-up by the disposal agency. The system utilized shall be subject to review and approval by the Design Review Board. 10. Pursuant to Government Code section 66474.9, the applicant (including the developer or any agent thereof) shall defend, indemnify, and hold harmless the Town of Danville and its agents, officers, and employees from any claim, action, or proceeding against the Town or its agents, officers, or employees to attack, set aside, void, or annul, the Town's approval concerning this rezoning application, which action is brought within the time period provided for in Section 66499.37. The Town will promptly notify the applicant of any such claim, action, or proceeding and cooperate fully in the defense. 11. The location, design and number of gang mailbox structures serving the project shall be subject to review and approval by the Design Review Board and the local Postmaster. 12. Unless explicitly authorized in these conditions of approval, development of the subject property shall be consistent with the Preliminary Owner Participation - Real Property Sales Agreement (OPA) covering the Charlotte Wood Intermediate School site and #1 Hartz Court. PAGE NO. 24 RESOLUTION NO. 93-34 13. 14. 15. Not less than fifteen percent of the dwelling units developed on the subject property shall be affordable to low and moderate income persons and households. Of that number, forty percent shall be affordable to very low income households, pursuant to California Health and Safety Code, Section 33413(b)(2). The production of these affordable units may be accomplished by the applicant by one of the methods outlined in the Preliminary Owner Participation - Real Property Sales Agreement (OPA) covering the property (i.e., produce some or all the units on-site or pay a specified in-lieu inclusionary housing fee to the Danville Community Development Agency). The applicant shall diligently pursue the necessary approvals through Caltrans to secure right of entry and the appropriate landscape easement/license to be able to install, at the applicant's cost, off-site landscaping within the State-controlled freeway right-of-way for the entire length of the property's easterly property boundary, or for that area deemed appropriate upon review of the final landscape and irrigation plan developed for this area. If a sound wall is installed as the noise attenuation system for the project, planting shall be for both the area behind the wall (i.e., the slope area west of the proposed wall location) and for the area in front of the wall (i.e., vine planting to cover the east side of the wall). Plant materials and planting ratios utilized shall be subject to review and approval by the Town's Planning Division and Caltrans. Irrigation shall be by a drip irrigation system, the design of which shall be acceptable to the Town and Caltrans, that can be abandoned once the planting material has established itself (estimated to be between three and five years). The noise study prepared for this project establishes that the future residents will be subjected to inappropriate noise levels if existing and future freeway noise is not mitigated to an appropriate level. Table 3 of the August 6, 1993 Salter noise study establishes the level of noise attenuation that would be provided if a twelve foot sound wall was established along the project's eastern boundary. While the noise study assumes that system to be used to attenuate existing and future freeway noise impacts will be a sound wall placed at the hinge point of the freeway (i.e., at the western edge of pavement), an alternative noise attenuation system may be utilized if it provides comparable mitigation of interior and exterior noise levels and is determined to be an acceptable alternative by the Planning Commission. If a sound wall is installed as the noise attenuation system for the project, the design and construction materials of the sound wall shall be reflective of PAGE NO. 25 RESOLUTION NO. 93-34 the "permanent" wall (i.e., the individual block construction wall, not the pre-fabricated concrete panel construction used elsewhere in the 1-680 corridor). The precise location, height, design and construction materials of the wall shall be subject to review and approval of the City Engineer and Caltrans prior to installation. 16. The pool and recreation area proposed for development in the northwest corner of the project shall be installed in conjunction with the construction of the second phase of the project (i.e., construction of the 22+ through 44+ unit). Prior to issuance of building permits for any unit in the project, a security guarantee, in a form and amount acceptable to the Town of Danville, shall be established to guarantee the construction of the pool and recreation area cited above. 17. Site demolition of existing buildings and accessory structures shall be done all at once. Prior to construction of the units in the first phase of development, the site shall be cleared and leveled to the satisfaction of the City Engineer.
