HomeMy WebLinkAbout2022-13RESOLUTION NO. 2022-13 APPROVING DEVELOPMENT PLAN REQUEST DEV21-0006, TREE REMOVAL REQUEST TR22-0039, AND AN ADDENDUM TO A PREVIOUSLY APPROVED FINAL ENVIRONMENTAL IMPACT REPORT ALLOWING THE DEVELOPMENT OF A 57-UNIT SENIOR CONDOMINIUM PROJECT ON A 1.88 ACRE SITE LOCATED AT 359 & 375 WEST EL PINTADO ROAD APN: 200-140-011, 012 WHEREAS, GMMR LLC (Owner) and DIAMOND CONSTRUCTION, INC. (Applicant) have requested approval of a Development Plan application to construct a 57-unit senior condominium project; and WHEREAS, a Tree Removal permit (TR22-0039) is requested to allow the removal of nine Town-protected trees; and WHEREAS, the site is located at 375 & 359 West El Pintado Road, and further identified as APNs: 200-140-011, 012; and WHEREAS, an Addendum to a previously certified Final Environmental Impact Report (FEIR) related to the approval of a previous development application (General Plan Amendment GPA2015-0001, Preliminary Development Plan – Rezoning PUD2015-0001, Major Subdivision, and a Final Development Plan DP2015-0065) has been prepared for the project; and WHEREAS, pursuant to the State Density Bonus Law, a 20 percent density bonus is proposed for the project, extending the overall unit density of the development from 25 to 30 units per acre in exchange for the provision of a 100 percent age restricted senior housing development; and WHEREAS, the previously certified FEIR and Addendum have found that the proposed project would not have any significant environmental impacts with the incorporation of recommended mitigation measures; and WHEREAS, all recommended mitigation measures have been included as recommended conditions of approval for the project; and WHEREAS, a staff report was prepared recommending that the Planning Commission approve the requests; and WHEREAS, public notification for the public hearing to consider this proposal was provided consistent with all requirements of the law; and DocuSign Envelope ID: B77D4A7E-86A5-4AAF-B808-F9F07FB1BBF0 PAGE 2 OF RESOLUTION NO. 2022-13 RESOLVED, that the Planning Commission of the Town of Danville approves Development Plan request DEV21-0006, Tree Removal permit TR22-0039, and an Addendum to a previously approved Final Environmental Impact Report allowing for the development of a 57-unit senior condominium project on a 1.88 acre site located at 359 & 375 West El Pintado Road. FINDINGS OF APPROVAL Final Development Plan – Major Subdivision 1. The proposed subdivision is in substantial conformance with the goals and policies of the Danville 2030 General Plan and the site’s Mixed Use land use designation which allows multiple family residential development in the range of 20-25 units per acre. 2. The design of the proposed subdivision is substantially in conformance with the site’s P-1; Planned Unit Development District. The P-1; Planned Unit Development District is listed as a consistent zoning designation under the site’s General Plan Mixed Use land use designation. 3. The design of the subdivision and the type of associated improvements will not likely cause serious public health problems, because water and sanitary facilities and services will be available to the parcels. The project has been reviewed by the San Ramon Valley Fire Protection District, Central Contra Costa County Sanitary District, East Bay Municipal Utility District, and the Town’s Building Division and it was determined that the site is adequately served by public facilities and services. In addition, the previously certified FEIR and the revised Initial Study of Environmental Significance prepared for the project did not find any potential significant impacts related to the provision of public services. 4. The density of the development is physically suitable for the subject site and surrounding neighborhood because the proposed development is similar in size and density to the residential development adjacent to the site to the west, and is compatible on scale to the commercial development to the north and east. The project provides for an adequate buffer and transition to the single family residential area to the south. 5. The design of the proposed subdivision and improvements are not likely to cause substantial environmental damage or subsequently injure fish or wildlife or their habitat, in part because the project site is an area where development has previously occurred. Biological resources were reviewed as part of the previously certified FEIR prepared for the project and found that the development would not DocuSign Envelope ID: B77D4A7E-86A5-4AAF-B808-F9F07FB1BBF0 PAGE 3 OF RESOLUTION NO. 2022-13 have a significant impact on biological resources with mitigation incorporated. 6. The design of the proposed subdivision and proposed improvements would not conflict with easements, acquired by the public at large, for access through or use of property within the proposed subdivision. There are currently no existing public easements for access through or use of the subject properties. Tree Removal Permit The project as proposed would remove 43 trees. Of the 43 trees to be removed, nine trees have been determined to be protected trees under the provision of the Town’s Tree Preservation Ordinance. The findings below address only the nine trees designated as protected under the Town’s Tree Preservation Ordinance. The previously approved FEIR and the Addendum to the FEIR for the project analyzes the potential environmental impacts for all the tree to be removing, whether or not they are designated as protected. 1. Necessity. The primary reason for removal of the Town-protected trees is that preservation of those trees would be inconsistent with the proposed residential development of the property, including the creation of a new roadway system and grading to create residential development pads. 2. Erosion/surface water flow. Removal of the Town-protected trees will not cause significant soil erosion or cause a significant diversion or increase in the flow of surface water. 3. Visual effects. With respect to other trees in the area, the project site contains a significant number of additional trees, including additional Town-protected Oak trees that would not be removed for the project. In addition, the project proponent will be required to replace all Town-protected trees to be removed with trees of an approved species and of a cumulative number and diameter necessary to equal the diameter of the tree(s) which have been approved for removal in accordance with the Town’s Tree Preservation Ordinance. Tree replacement will be conducted in accordance with the Town’s requirements, including planting a mixture of small and large box trees to meet the cumulative diameter number of the removed trees. The project proponent will also be required to replace all non-ordinance-species or size trees (i.e., trees less than 10 inches in diameter for single-trunk trees or less than 20 inches in diameter for multi-trunk trees) at a replacement-to-removal ratio of 1:1. Removal of the 43 trees, including nine Town-protected trees, will not significantly affect off-site shade or adversely affect privacy between properties due to the site’s topography, the other trees that would remain, and the locations of the trees in DocuSign Envelope ID: B77D4A7E-86A5-4AAF-B808-F9F07FB1BBF0 PAGE 4 OF RESOLUTION NO. 2022-13 relation to other properties.

Prior to the issuance of grading or building permits, the applicant shall submit written documentation that all requirements of the San Ramon Valley Fire Protection District (SRVFPD) and the San Ramon Valley Unified School District have been, or will be, met to the satisfaction of these respective agencies. * 5. The applicant shall submit to the Town of Danville fees required to file a Notice of Determination for this project as required by AB 3185. The fee shall be $3,271. This check shall be made payable to the Contra Costa County Recorder’s Office and shall be submitted to the Town within five days of project approval. DocuSign Envelope ID: B77D4A7E-86A5-4AAF-B808-F9F07FB1BBF0 PAGE 6 OF RESOLUTION NO. 2022-13 6. Prior to the commencement of ground disturbance, including site preparation and grading activities, the applicant will ensure that all construction workers are trained to recognize archaeological resources (e.g., obsidian and chert flakes and chipped stone tools; grinding and mashing implements such as slabs and handstones, and mortars and pestles; bedrock outcrops and boulders with mortar cups; and locally darkened midden soils containing some of the previously listed items plus fragments of bone, shellfish, and fire affected stones; fragments of glass, ceramic, and metal objects; milled and split lumber; and structure and feature remains such as building foundations and discrete trash deposits). The cultural resources awareness training shall be conducted by a qualified professional archaeologist with experience in training non-specialists. A record of completion of cultural resources awareness training for all construction workers shall be submitted to the Town of Danville prior to the issuance of a grading permit, and a copy of the training completion record shall be maintained onsite for the duration of construction activities. 7. If previously unidentified cultural resources are encountered during construction or land disturbance activities, work shall stop within 50 feet of the find and the Town of Danville shall be notified at once to assess the nature, extent, and potential significance of any cultural resource find. The applicant shall retain a qualified archaeologist to implement a Phase II subsurface testing program to determine the resource boundaries, assess the integrity of the resource, and evaluate the resource’s significance through a study of its features and artifacts. If the resource is determined significant, the Town of Danville may choose to allow the capping of the area containing the resource using culturally sterile and chemically neutral fill material. If such capping occurs, then a qualified archaeologist shall be retained to monitor the placement of fill upon the resource. If a significant resource will not be capped, the results and recommendations of the Phase II study shall determine the need for a Phase III data recovery program designed to record and remove significant cultural materials that could otherwise be tampered with. If the resource is determined to be not significant, no capping and/or further archaeological investigation or mitigation shall be required. The results and recommendations of the Phase II study shall determine the need for construction monitoring. If monitoring is warranted, a qualified archaeologist shall be retained by the applicant to be present during all earth moving activities that have the potential to affect archaeological or historical resources. A monitoring report shall be submitted to the Town upon completion of construction. 8. If previously unidentified human remains are encountered during project construction, State Health and Safety Code Section 7050.5 shall be adhered to, which requires that no further disturbance shall occur until the County Coroner has made the necessary findings as to origin and disposition pursuant to Public Resources Code Section 5097.98. If the remains are determined to be of Native American descent, the coroner has 24 hours to notify the NAHC. The NAHC would then identify the person(s) thought to be the Most Likely Descendent (MLD) of the DocuSign Envelope ID: B77D4A7E-86A5-4AAF-B808-F9F07FB1BBF0 PAGE 7 OF RESOLUTION NO. 2022-13 deceased Native American, who would then help determine what course of action should be taken in dealing with the remains. * 9. Construction activity shall be restricted to the period between the weekday hours of 7:30 a.m. to 5:30 p.m. (Monday through Friday), unless otherwise approved in writing by the City Engineer for general construction activity and the Chief Building Official for building construction activity. 10. At a minimum, all on-site structures shall include the following to achieve an acceptable interior noise level: • Air conditioning or a mechanical forced–air ventilation system so that windows and doors may remain closed • Double-paned windows and sliding glass doors mounted in low air infiltration rate frames (0.5 cubic feet per minute, per ANSI specifications) • Solid core exterior doors with perimeter weather stripping and threshold seals • Roof and attic vents facing away from I-680 11. The applicant shall apply the following measures during construction of the project. • Construction Staging. The contractor shall provide staging areas on-site to minimize off-site transportation of heavy construction equipment. These areas shall be located to maximize the distance between activity and sensitive receptors. This would reduce noise levels associated with most types of idling construction equipment. • Mufflers. Construction equipment shall be properly maintained and all internal combustion engine driven machinery with intake and exhaust mufflers and engine shrouds, as applicable, shall be in good condition and appropriate for the equipment. During construction, all equipment, fixed or mobile, shall be operated with closed engine doors and shall be equipped with properly operating and maintained mufflers, consistent with manufacturers’ standards. • Electrical Power. Electrical power, rather than diesel equipment, shall be used to run compressors and similar power tools and to power any temporary structures, such as construction trailers or caretaker facilities. • Equipment Staging. All stationary equipment shall be staged as far away from the adjacent multi-family residential development as feasible. • Equipment Idling. Construction vehicles and equipment shall not be left idling for longer than five minutes when not in use. • Workers’ Radios. All noise from workers’ radios shall be controlled to a point that they are not audible at sensitive receptors near construction activity. • Smart Back-up Alarms. Mobile construction equipment shall have smart back-up alarms that automatically adjust the sound level of the alarm in response to ambient noise levels. Alternatively, back-up alarms shall be disabled and DocuSign Envelope ID: B77D4A7E-86A5-4AAF-B808-F9F07FB1BBF0 PAGE 8 OF RESOLUTION NO. 2022-13 replaced with human spotters to ensure safety when mobile construction equipment is moving in the reverse direction. • Disturbance Coordinator. The applicant shall designate a disturbance coordinator who shall be responsible for responding to any local complaints about construction noise. The noise disturbance coordinator shall determine the cause of the noise complaint (e.g., starting too early, bad muffler, etc.) and shall require that reasonable measures warranted to correct the problem be implemented. A telephone number for the disturbance coordinator shall be conspicuously posted at the construction site. • Construction Notice. Two weeks prior to the commencement of construction and grading at the project site, the applicant shall install a 3-foot by 3-foot sign at the project entry that discloses the allowable construction work days and hours, the planned construction schedule, and the contact name and phone number for residents to call for construction noise related complaints. All reasonable concerns shall be rectified within 24 hours of receipt. * 12. The applicant shall provide security fencing, to the satisfaction of the City Engineer and/or the Chief Building Official, around the site during construction of the project. * 13. A watering program which incorporates the use of a dust suppressant, and which complies with Regulation 2 of the Bay Area Air Quality Management District shall be established and implemented for all on and off-site construction activities. Equipment and human resources for watering all exposed or disturbed soil surfaces shall be supplied on weekends and holidays as well as workdays. Dust-producing activities shall be discontinued during high wind periods. * 14. All physical improvements shall be in place prior to occupancy of any structure in the project. If occupancy within the project is requested to occur in phases, all physical improvements shall be required to be in place prior to occupancy except for items specifically excluded in a construction- phases occupancy plan approved by the Planning Division. No structure shall be occupied until construction activity in the adjoining area is complete and the area is safe, accessible, provided with all reasonably expected services and amenities, and appropriately separated from remaining additional construction activity. A temporary vehicular turnaround shall be provided at the end of the completed section of loop roadway to allow separation of resident traffic and construction traffic. * 15. The applicant shall submit a written Compliance Report detailing how the conditions of approval for this project have been complied with as part of the initial submittal for the final map, plan check, and/or building permit DocuSign Envelope ID: B77D4A7E-86A5-4AAF-B808-F9F07FB1BBF0 PAGE 9 OF RESOLUTION NO. 2022-13 review process (whichever occurs first). This report shall list each condition of approval followed by a description of what the applicant has provided as evidence of compliance with that condition. The applicant must sign the report. The report is subject to review and approval by the City Engineer and/or Chief of Planning and/or Chief Building Official and may be rejected by the Town if it is not comprehensive with respect to the applicable conditions of approval. * 16. Planning Division sign-off is required prior to final Building Inspection sign-off. 17. The applicant shall be responsible for washing the exterior of abutting residences and businesses, and cleaning pools, patios, etc. at the completion of each phase of project mass grading activity. The residences to receive cleaning, the extent of the cleaning efforts to be performed, and the timing (and frequency) of such cleaning shall be subject to review and approval by the Planning Division. B. SITE PLANNING * 1. All lighting shall be installed in such a manner that lighting is generally down directed and glare is directed away from surrounding properties and rights-of-way. * 2. 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. 3.

The plan shall include common names of all plant materials and shall indicate the size that various plant materials will achieve within a five-year period of time. * 2. All plant material shall be served by an automatic underground irrigation system and maintained in a healthy growing condition. Irrigation shall DocuSign Envelope ID: B77D4A7E-86A5-4AAF-B808-F9F07FB1BBF0 PAGE 10 OF RESOLUTION NO. 2022-13 comply with Town of Danville Landscape Ordinance #91-14 and landscape guidelines and shall be designed to avoid runoff and overspray. Proposed common maintenance lawn areas within the project shall not exceed a maximum of 25 percent of proposed common landscaped areas. * 3. All trees shall be a minimum of 15-gallon container size. All trees shall be properly staked. All remaining shrubs used in the project, which are not used as ground cover, shall be a minimum of five gallons in size. * 4. All landscaped areas not covered by shrubs and trees shall be planted with live ground cover or covered with mulch. All proposed ground cover shall be placed so that it fills in within two years. * 5. If site construction activity occurs in the direct vicinity of the on-site and off-site protected trees, a security deposit in the amount of the assessed value of the tree(s) (calculated pursuant to the Town’s Tree Protection Ordinance) shall be posted with the Town prior to the issuance of a grading permit or building permit to maximize the probability that the affected trees will be retained in good health. The applicant shall be required to secure an appraisal of the condition and value of all affected trees. The appraisal shall be done in accordance with the current edition of the “Guide for Establishing Values of Trees and Other Plants,” by the Council of Tree and Landscape Appraisers under the auspices of the International Society of Arboriculture. The appraisal shall be performed by a Certified Arborist, and shall be subject to review and approval by the Chief of Planning. A tree preservation agreement shall be prepared that outlines the intended and allowed use of funds posted as a tree preservation security deposit. That portion of the security deposit still held by the Town two full growing seasons after project completion shall be returned upon verification that the trees covered by the deposit are as healthy as can be provided for under the terms of the tree preservation agreement. 6. The proposed good-neighbor fence on the south side of the project shall be seven feet tall, including six feet of solid wood and a one-foot lattice top. D. ARCHITECTURE * 1. All ducts, meters, air conditioning and/or any other mechanical equipment whether on the structure or on the ground shall be effectively screened from view with landscaping or materials architecturally compatible with the main structures. * 2. The street numbers for each building in the project shall be posted so as to DocuSign Envelope ID: B77D4A7E-86A5-4AAF-B808-F9F07FB1BBF0 PAGE 11 OF RESOLUTION NO. 2022-13 be easily seen from the street at all times, day and night by emergency service personnel. * 3. Samples of final materials and the proposed color palette shall be submitted for review and approval by the Design Review Board prior to the issuance of building permits for the project. 4. Final architectural elevations, details and revisions shall be submitted for review and approval by the Design Review Board prior to issuance of building permits for the project. Six full size sets of construction drawings for the project shall be submitted to the Planning Division for design review concurrent or prior to, the applicant initiating the Building Division plan check process. In addition, final colors, and all proposed materials, including building siding, balcony railing, and roof equipment screening, shall be subject to review and approval by the DRB prior to issuance of building permits. The DRB reserves the right to refer the final details back to the Planning Commission for review and approval. * 5. The project covenants, conditions and restrictions shall provide a review and approval process for any proposed repainting or re-roofing of exteriors of the units in this project. E. BIOLOGICAL RESOURCES 1. If Modified Project activities must be conducted during the nesting season (March 1 and September 1), a pre-construction nesting bird survey will be conducted by a qualified biologist no more than 14 days prior to vegetation removal or initial ground disturbance. The survey will include the project site and surrounding vicinity to identify the location and status of any nests that could potentially be affected either directly or indirectly by Project activities. If active nests of native nesting bird species are located during the nesting bird survey, a work exclusion zone will be established around each nest by the qualified biologist. Established exclusion zones will remain in place until all young in the nest have fledged or the nest otherwise becomes inactive (e.g., due to predation). Appropriate exclusion zone sizes will be determined by a qualified biologist and will vary based on species, nest location, existing visual buffers, noise levels, and other factors. An exclusion zone radius may be as small as 50 feet for common, disturbance-adapted species, or as large as 250 feet or more for raptors. Exclusion zone size will be reduced from established levels by a qualified biologist if nest monitoring findings indicate that Project activities do not adversely impact the nest, and if a reduced exclusion zone would not adversely affect the nest. DocuSign Envelope ID: B77D4A7E-86A5-4AAF-B808-F9F07FB1BBF0 PAGE 12 OF RESOLUTION NO. 2022-13 2. To avoid impacts to roosting bats, tree removal and building demolition should occur between October 1 and March 31, outside of the maternity roosting season (when female bats may have dependent young). If tree removal or building demolition must occur between April 1 and September 30, a bat roost habitat assessment should be conducted by a qualified biologist. The bat roost habitat assessment would determine the likelihood of the Project site supporting roosting bats. If the assessment identifies suitable or potentially occupied roosts within the Project site, a pre-construction bat survey should be performed no more than 14 days prior to tree or building removal using site appropriate survey methods to determine if potential roost structures are occupied. If special-status bat species are detected during these surveys, appropriate, species and roost-specific mitigation measures will be implemented. Such measures may include postponing the removal of the trees or building until the end of the maternity roosting season, exclusionary work buffers, or consultation with CDFW. 3. The Modified Project will obtain a Section 404 Permit from the Corps and a Section 401 Water Quality Certification from the RWQCB prior to any impacts to waters of the U.S. and State. The Project will prepare a Habitat Mitigation and Monitoring Plan (MMP) to satisfy the requirements of the Corps and RWQCB permits to achieve no net-loss of wetlands. To mitigate for impacts to sensitive and natural communities, the applicant proposes to construct a 285-linear feet main channel and a 160 liner feet meandering tributary channel; the total low flow flat channel bottom area will be 6,960 square feet (0.16 acre) that is designed to develop into wetlands. The total mitigation area below top-of-bank will be 10,280 square feet (0.24 acre). This will provide 1:1 replacement for the total linear feet impacts and 4:1 replacement for the impacted acreage of channels. The total area below top-of-bank will be replaced at a 2:1 mitigation ratio. 4. The Modified Project will obtain a Lake and Streambed Alteration Agreement from the CDFW to proceed with proposed impacts to CDFW jurisdictional riparian habitat. All compliance measures included in the permit will be adhered to. 5. The Modified Project will replant valley oak and willow trees at a mitigation ratio of 2:1 to offset the removal of valley oak and willow trees from the riparian sensitive natural community. A replanting plan and a MMP will be submitted to CDFW prior to implementation. 6. The applicant shall comply with Town requirements (DMC Section 32-79), as applicable, to plant on-site or off-site replacement trees for removed protected trees which are of a cumulative diameter necessary to equal the diameter of trees approved for removal as determined by the Town’s Planning Division. For the non- DocuSign Envelope ID: B77D4A7E-86A5-4AAF-B808-F9F07FB1BBF0 PAGE 13 OF RESOLUTION NO. 2022-13 Town protected trees that would be removed as part of the project, the applicant shall plant new minimum 15-gallon trees either on-site or off-site, as determined by the Town, at a 1:1 ratio. The exact locations and tree species shall be subject to review and approval by the Town’s Planning Division. 7. The following measures shall be implemented prior to the start of construction for all trees not designated for removal. • Trees to be retained on-site shall be temporarily fenced with chain-link or other substantial, highly visible material while all grading and construction activities occur, including landscaping activities that require substantial ground disturbance (more than the use of hand tools). The fencing shall be five feet from the dripline of the canopy, at least six-feet high, staked to prevent collapse, and shall contain signs identifying the protection area. • When construction activities occur within five feet of the dripline, a certified arborist shall be on site to monitor and make recommendations. • All roots shall be cut cleanly, if possible, back to a lateral branching root. Cuts should be made at right angles to the roots. • If canopy trimming is needed it shall be done under the supervision of an International Society of Arboriculture (ISA) Certified Arborist and by an ISA Certified Tree Worker. Trees shall be pruned according to American National Standards Institute (ANSI) 300 standards. ANSI 300 provides guidelines for pruning trees and other woody plants. F. AIR QUALITY 1. In order to reduce exposure of proposed residences to toxic air contaminants emissions from vehicles on I-680, the applicant shall submit to the Town of Danville for review and approval a ventilation proposal prepared by a licensed design professional for all on-site buildings that describes the ventilation design and how that design ensures all dwelling units would be below the excess cancer risk level of 10 in one million established by the Bay Area Air Quality Management District. The ventilation proposal shall include, but is not limited to, the following measures: a) If the proposed buildings would use operable windows or other sources of infiltration of ambient air, the development shall install a central HVAC system that includes high efficiency particulate filters (a MERV rating of 13 or higher). These types of filters are capable of removing approximately 90 percent of the DPM emissions from air introduced into the HVAC system. The system may also include a carbon filter to remove other chemical matter. Filtration systems must operate to maintain positive pressure within the building interior to prevent entrainment of outdoor air indoors. b) If the development limits infiltration through non-operable windows, a suitable ventilation system shall include a ventilation system with filtration specifications equivalent to or better than the following: (1) American DocuSign Envelope ID: B77D4A7E-86A5-4AAF-B808-F9F07FB1BBF0 PAGE 14 OF RESOLUTION NO. 2022-13 Society of Heating, Refrigerating and Air-Conditioning Engineers MERV- 13 supply air filters, (2) greater than or equal to one air exchanges per hour of fresh outside filtered air, (3) greater than or equal to four air exchanges per hour recirculation, and (4) less than or equal to 0.25 air exchanges per hour in unfiltered infiltration. These types of filtration methods are capable of removing approximately 90 percent of the DPM emissions from air introduced into the HVAC system. c) Windows and doors shall be fully weatherproofed with caulking and weather-stripping that is rated to last at least 20 years. Weatherproof should be maintained and replaced by the property owner, as necessary, to ensure functionality for the lifetime of the project d) Where appropriate, install passive (drop-in) electrostatic filtering systems, especially those with low air velocities (i.e., 1 mph) e) Ensure an ongoing maintenance plan for the HVAC and filtration systems. Manufacturers of these types of filters recommend that they be replaced after two to three months of use. The applicant shall inform occupants regarding the proper use of any installed air filtration system. G. PARKING * 1. All parking spaces shall be striped and provided with wheel stops unless they are fronted by concrete curbs, in which case sufficient areas shall be provided beyond the ends of all parking spaces to accommodate the overhang of automobiles. * 2. Where authorized, compact car spaces shall be clearly designated with appropriate pavement marking or signage. Compact spaces shall be no less than 8 feet by 16 feet in size, including allowable overhang. * 3. Regulatory signage/curb painting for the non-parking side of the interior loop roadway shall be provided, if deemed necessary, to the satisfaction of the San Ramon Valley Fire Protection District and the City Engineer. H. GRADING * 1. Any grading on adjacent properties will require prior written approval of those property owners affected. * 2. At least one week prior to commencement of grading, the applicant shall post the site and mail to the owners of property within 300 feet of the exterior boundary of the project site, to the homeowner associations of nearby residential projects and to the Town of Danville Development DocuSign Envelope ID: B77D4A7E-86A5-4AAF-B808-F9F07FB1BBF0 PAGE 15 OF RESOLUTION NO. 2022-13 Services Department, a notice that construction work will commence. The notice shall include a list of contact persons with name, title, phone number and area of responsibility. The person responsible for maintaining the list shall be included. The list shall be kept current at all times and shall consist of persons with authority to initiate corrective action in their area of responsibility. The names of individuals responsible for dust, noise and litter control shall be expressly identified in the notice. 3. In accordance with the recommendations of the preliminary geotechnical investigation, the applicant shall conduct a design-level geotechnical investigation.
