38 HIGH ROCK FARMS PHASE ONE -PRELIMINARY PLAN This subdivision was continued pending the presentation of the water resource report, which was heard on May 1, 2001. The report included three documents: 1. Water Resource Committee Report 2. "Investigation of Ground-Water Availability and Quality in Orange County, North Carolina" Water-Resources Investigations Report 00-4286 3. Reference to a 199fi report regarding: Calculation of Recharge Area Required for Single Family Residential Dwellings served by individual wells. and wastewater treatment systems based on modified methodology contained in Groundwater Recharge to the Regolith-Fractured Crystalline Rock Aquifer System, Orange County, North Carolina as prepared by the U.S. Geologival Survey, Water - Resources Investigation Report 96-4220, 199G. Demand based on persons/family in underlying census tract, 1990. All of these reports are independent at this point, on the decision regarding the subdivision since these reports are informational and not regulatory. There may be interest in the board to review and analyze the technical reports and committee recommendations and suggest regulatory changes that would be processed through the public hearing process. The reports are generalized at this point and do not have specific intent to describe the case conditions at a particular site. However, in a generalized manner the reports do conjecture two issue areas; 1. Maximum well yields in this area is ranked a 4 on a scale of 1 to 6 for yield per foot and 0-25 gallons per minute. 2. 'Sustainable lot size' (i.e. Recharge Area Required...) for this area suggests that minimum lot sizes could range between 1.5fi acres and 2.1 acres depending on demand .gallons of household consumption. From a grass acreage standpoint High Rock Farms Phase I would fulfill the gross sustainable lot size meaning that even though the lots average .94 acres that with adjacent open space, the gross lot size is 2.12 acres. I caution the use of this generalization since there is need for much more analysis,. This report information is consistent with the general direction. of our comprehensive plan research on land use sustainability in rural areas of the county. Amore thorough analysis of its land use and zoning implications will be forthcoming in late summer to early fall 2001.
