INITIAL STUDY (CONT'D) f SU-92-15 NOTE: In May of 1987, General Plan Map Amendment application- (GP-87-16) , Zone Reclassification application (ZR-87-35) , and Major Subdivision application (SU-87-23) were submitted to the Planning Department. The project which was known as Morada Meadows was analyzed for it potential environmental impacts in Environmental Impact Report (EIR) No. ER-88-1. On March 17, 1988, the Morada Meadows project was heard by the Planning Commission and denied. The appeal to the Board of Supervisors was heard on July 20', 1989 and the appeal was denied without prejudice. At that hearing, ER-88-1 was certified by the Board of Supervisors. As this area is now planned for residential development (as evidenced by the recent action of the Board of Supervisors) , all that is being processed now is an application for a Major Subdivision, SU-92-15, which is consistent with the site's Rural Residential General Plan designation and zoning. The EIR (ER-88-1) prepared for the previous Morada Meadows project was used for technical background information for the preparation of this Initial Study. This EIR did note several significant unavoidable adverse impacts, however, these were not associated with the subdivision, but were policy related relative to changing the General Plan designation from Agriculture to Rural Residential. The prior Major Subdivision Application proposed 39 lots ranging from 65, 000 square. feet to 83,700 square feet, whereas this proposal is for 37 lots ranging in size from 44,000 square feet to 50, 000 square feet. 1. (b) The Environmental Impact Report (ER-88-1) noted that there is the. potential impact for groundwater quality degradation as a . result of nitrate loading from the i proliferation of on-site septic systems. ER-88-1 stated that the feasibility of on-site sewage disposal will primarily be dependent upon soil percolation at each site. The- applicant's proposal of two community wells for potable water, would mitigate the potential risk of water quality degradation caused by nitrate loading from the on-site septic systems. Also, according to ER-88-1,. the anticipated water demands from the proposed project are not expected to significantly affect the area wide water table. Based on a peak demand of one gallon per minute per unit, one well for the entire project would experience less than one foot of drawdown.
