g.-; - 9d • MEMORANDUM TO: ORANGE COUNTY B ARD OF COMMISSIONERS FROM: MARVIN COLLINS, PLANNING DIRECTOR DATE: APRIL 2, 1990 SUBJECT: PROPOSED IMPERVIOUS SURFACE LIMITS - UNIVERSITY LAKE WATERSHED COPIES: JOHN •LINK, COUNTY MANAGER GEOFFREY GLEDHILL, COUNTY ATTORNEY / . As part of the Administration' s recommeridat ion on proposed amendments to the Zoning Ordinance (Action Agenda Item #K-E) , a modification to the Planning Director' s sliding scale of impervious surface ratios was proposed. The Planning Board' s rationale for recommending the modification was to establish more incentive for the creation of larger=than-5-acre lots. The same basic limits of 6% for 5-acre lots and 12% for 2-acre lots would still apply. However, a change would result for lots larger than 5 acres. Instead of a 4% cap at 6 acres, the 4% cap would occur when lot sizes reached 7 acres in size. Initially, the modification was viewed by the Administration as an enhancement of the scale. The benefits to be derived, however, are only for lots between 6. 1 and 7. 0 acres in size. Once 7. 0 acres exceeded, the amount of impervious surface permitted is the same, not only for the Planning Board and Planning Director' s proposal, but for the 13--point agreement as well (see attached chart and graph) . - '14hi, Ie the proposal by. the Planning Board may have merit, the - -"' AthainiBtration feels that adherence to the basic strategy as = Y'. i e%o fort 2-acre lots it with' sliding cscale) y is c,t 5-acre lots desirable .c ;::▪ approach.
