z~ ~ ~ Kimley-Horn ~ ® and Associates, inc. Robert Davis February 3, 2000 Page 2 change the number of lots shown on the plan have been reduced to 43 lots, one less than approved by the Planning Board. Utilities The Orange Alamance Water System, Inc. has approved the connection of this site to their system and a letter of their action is attached. The Orange County School Board has approved an easement permitting sanitary sewer to connect to the existing Orange County sanitary sewer line that runs along the northern edge of the Efland-Checks Elementary School property. Be- cause of the number of extra meetings held by the School Board to consider re- districting plans and the recent weather, the preparation and approval of official minutes recording'the School Board's approval are not yet. Susan Levy has been told by the board's secretary that she will provide a letter to Habitat as soon pos- sible. Impervious Surface Limitations The Richmond Hills Subdivision site is located in the Eno River Protected Wa- tershed and therefore has impervious surface limitations. With structural BMP's the impervious limit is 30%, without structural BMP's the limit is 12%. The Richmond Hills plan proposes to construct less than 12% impervious surface on the site and' therefore does not show structural water quality facilities. The following table shows the allocation of the 12% coverage. Total Site in 5 uare Feet 1,751275 SF Maximum Im envious Surface (12%) 210,153 SF Paved Roadwa surface - 69,696 SF Im ervious surface for 43 lots 140,457 SF Avera a er lot im envious surface 3,266 SF We did not place a note referring to impervious surface limitations on the sub- mitted preliminary plan, but will do so on our next submission. We propose a statement something like: "The maximum impervious surface al- lowed for this development is 210,153 square feet (12% of the total site area). Starting with the first phase of development, the subdivision developer shall keep a running record of the impervious surface area approved to date and constructed to date and shall provide an updated tabulation at the time of building permit re- quests for all lots."
