' 111 Chestnut Oaks Sub i ivision Habitat for Humanity of Orange County Site Analysis -- December 23. 1987 The site is covered primarily by a mature oak-hickory forest,especially on the portion to the west of the unnamed intermittent stream that flows north-south dividing the site. A portion of the eastern portion of the site is covered with grasses,a remnant of recent past farming on the site. The tree line is Shown on the site plan. The topology of the site is gently rolling. Stme localized slopes over 15 degrees exist in the vicinity of the intermittent stream. Mot of these slopes are located in the area designated as open space,although the rear of�lots #24, #25,and #26 have slopes over 15 degrees. Habitat for Humanity, Inc.will not locate buildings on those portions of the lots with slopes greater than 15 percent. Only minor disturbances to the slopes for the one roadway crossing and one pedestrian trail crossing are planned. Five foot contour lines are shown on the site plan. Soils are being analyzed by the County sanitarian for their ability to support individual wastewater treatment systems, Drainage patterns generally flow in an east;west direction toward the intermittent stream. The stream flows from a pond located on property to the north of the Chestnut.Oaks site. A high point of the property is located on the western portion of the site;thus,some drainage would be toward the west and north site boundaries. Drainage patterns are evident from the contour lines on the site plan. In addition, preliminary culvert locations to carry drainage beneath roadways are indicated on the plan. Culvert sizing and design, being prepared by Habitat for Humanity's engineer. will be in accordance with County requirements. The accompanying subdivision plat-preliminary provides further site information. In addition,Exhibit A attached to this site analysis includes data on roadway curves. Cluster Development Application Requirements (Subdivision Regulations Section IV-B-10-f) a. This application is for a Cluster Development Sub ivision -Preliminary Plan. b. The 68-acre project site's underlying zoning is for one dwelling unit per two acres. The principal difference between the proposed plan and a standard two-acre subdivision plan is that the applicant proposes to locate 31 homesites of 1 acre (43.560 square feet)or more on the site. By clustering homes on smaller-than-standard lots in two locations-- to the east of the intermittent stream and near the rear of the site to the west of the stream--the applicant is able to provide more open space and greater stream setbacks than are required by County regulations or would be possible with two- acre homesites. The clustering will not increase the number of dwelling units that could otherwise be located on the site. Clustering sh 4uld reduce the amount of impervious surfaces that would occur with a standarc subdivision, by reducing the amount of roadway pavement necessary to serve the wellings.
