Staff had recommended denial mainly because five of the six proposed lots were at variance to the minimum lot size. Revised plans were received October 29, 1987, with a reduction of lots and conforming- lot size. The proposal being consistent with the General Plan and in compliance with A-20 zoning on the property, was approved December 16, 1987, with conditions including provisions for further review to assure that buildings will be visually compatible in the area and that almost half of the entire site would be placed in a scenic easement. ACTION OF BOARD ON . July 26, 1988 APPROVED AS RECOMMENDED OTHER X The Board of Supervisors on July 12, 1988, closed the public hearing on the above matter and deferred the matter to today for report from the Director of Community Development relative to the Williamson Act, the placement of the building sites and the preclusion of further subdivision of- the building sites. The Board having received conditions of approval from the Community Development Department, Supervisor Schroder commented on the conditions that addressed the concerns and expressed that he would like Condition-7,A to read structures shall be sited according to County Ridgeline Policy to give a little flexibility relative to the placement of the homes and not require determination today of where the homes would be sited. Supervisor Schroder moved acceptance of the recommendation of conditions of approval for Subdivision 6933 .
