Re: Bennington Forest Subdivision
Dear Mr. Rindner:
Our office has prepared the approved construction plans fir the referenced project.
The project consists of 142 fats located on 64.14 acres (:2.2) Dt.1A}. The anticipated average
impervious area per lot is between 2500 and 351)0 square feet. The roadways and sidewalks
consist of 5.83 acres of impervious area. With using a.n average impervious area per lot of
3200 square feet, the total impervious area would not exceed 30°fo using a net acreage of
54.93 acres which excludes 9.21. acres ~,f flaadplain. Due to the prnpased amounts of
density azld impervious areas, na starn~water controls where required by the Town of
Matthetivs.
[f you should have any further questions ar need additional information, fee! free to

Summary of Impervious Calculations for Bennington Forest Subdivision
Total Project Area
+ 64.14 Acres
Less Fioodplain + 9.21 Acres
Total Single Family Site Area + 54.93 Acres or 2,392,751 SF
Proposed Maximum 30% Impervious Allowable + 16.48 Acres or 717,825 SF
For Single Family Area
Roads, Curb and Gutter, and Sidewalks + 5.83 Acres or 253,884 SF
142 Lots Ca? 3200 SF !Lot *** + 1.0.43 Acres or 454,400 SF
Total Impervious Area Far Bennington Forest Subdivision + 16.26 Acres or 708,284 SF or 30%
Note: No Amenity Area is proposed for this site..
"**~"" Note: The developer has not selected a specific home style at this time. it is
expected that based on similar projects in the area in which 3,400 SF was allotted
(Gilead Ridge) for TO' wide lots and 3,000 SF was allotted for 70' lots (Villages at
Rosedale), that the average of 3,200 sQ. ft of impervious area per lot is a reasonable
allowance for the proposed 65 ft. lots. At these ofher project locations the actual
built upon area was well short of the "allotment". ,., /f
