Resolution No. PC-96-52 Page 4 Grading in conjunction with the proposed development would maintain the exist- ing configuration of the site sloping downward from Del Valle Parkway towards the Arroyo Del Valle. Storm water runoff would be conveyed to the arroyo via an existing storm drain outfall. Sanitary sewer lines will drain towards the lines lo- cated in Del Valle Parkway. All units/lots would be graded to drain towards the private motorcourts or to a storm line; the decision would be made at the tentative map stage. The subject property is not located in the Alquist-Priolo Special Studies Zone. Requirements of the Uniform Building Code -- implemented by the City at the Building Permit review -- would ensure that building foundations and private street/on-site parking areas are constructed on satisfactorily compacted fill. Erosion control, stormwater runoff, dust suppression measures will be docu- mented in the final map and/or grading plan/permit and will be administered by the City's Building and Public Works Departments. To stabilize the steeper sections of the bank of the Arroyo Del Valle by the site, the applicant will install concrete and rip-rap material. However, to maintain the natural appearance of the arroyo, the applicant would end the concrete within 5' 0" of the top-of-bank and would place a layer of soil and native grasses over the concrete/rip-rap. F. Adequate public safety measures have been incorporated into the design of the proposed development plan: The developer would dedicate in fee title to Zone 7 the portion of the site's area from the top-of-bank of the Arroyo Del Valle down to the south property line. By accepting dedication of the bank, Zone 7 will be responsible for bank maintenance and repair. A geotechnical analysis of the slope bank, including test borings of the soil struc- ture, has identified measures which would be implemented by the developer to stabilize the steeper sections of the bank of the Arroyo Del Valle located by the project site. Based on these measures, Zone 7 staff is comfortable that the bank can be made stable. Deleting the fence between the project site and the Arroyo Del Valle means that the City of Pleasanton shall accept a recreation easement from Zone 7 over the portion of the site to be dedicated to Zone 7, and accepts the liability for this sec- tion of the Arroyo Del Valle.
