grade to canopy will have to be maintained for any new trees planted along Foothill Road. The emphasis of the fire management plan is to control the potential ignition sources of wildland fires; to prevent a "ladder fuel situation" where a fire can "climb" from grassland to low shrubs /scrub to low- hanging tree canopies and then to the home; to maintain existing trees and tree groupings; to allow new trees and tree groupings to buffer /screen the visibility of the new homes on these sites, if necessary. The application of these standards may restrict the scope of the future proposed designs. It is for this reason that staff intends to incorporate the details and standards of the fire management plan with the building and landscape guidelines for a comprehensive integrated document. Item j on Page 15 of this analysis should be revised to read: "Emerging trees must have a minimum 6 -foot spacing cleared from the edge of the canopy The minimum spacing should agree with the figure and, therefore, should be 6 feet, not 12 feet. Residential Fire Sprinkler Systems The proposed homes are required to be equipped with residential fire sprinkler systems. Adequate fire flow is present to serve the homes on these lots. The design of the fire sprinkler systems will be reviewed with the lot- specific design applications and building permit review. There is adequate water supply and pressure available to these sites for fire sprinkler systems without booster pumps or other special equipment. Grading /Urban Stormwater Runoff The existing site grades will be largely retained with the proposed project grading limited to the minimum grading for the driveway entrance, house and driveways, and a reasonably sized private yard area. The proposed building sites will be designed in conformance to the requirements of the National Pollutant Discharge Elimination System (NPDES) of the Clean Water Act: structures and paved areas will be designed to drain to bio- filter areas, swales, or comparable measures to pretreat and then dissipate the stormwater runoff. The project will be required through the grading and building permit and construction processes to incorporate best management practices to control erosion and to prevent discharges into the City's storm drain system resulting from this development. As conditioned the slope bank on the east side of the driveway to Lots 3 and 4 will be replaced with a combination of retaining walls and slope bank to reduce grading. The applicant concurs with this requirement. Geotechnical /Alquist Priolo Earthquake Fault Zone The Alquist Priolo Earthquake Fault Zone for the Calaveras fault traverses the lower portion of Lots 1, 2, and 4. The site was analyzed by the applicants' consultant, Engeo, Inc., with their findings peer- reviewed by Cotton Shires and Associates under supervision by the City Engineer. The Calaveras fault and fault zone was mapped on the Yee property by surveys and trenches completed by the Darwin Meyers firm in 1985. The fault zone with landslide areas is shown on Engeo's geotechnical surveys. Item 6.b., PUD- 87- 19 -03M Page 28 of 37 April 28, 2010
