Dear Glen,
The purpose of this letter is to document that the
proposed development of Tract A is in accordance with the
approved drainage report for Warren Farms, First Filing.
According to Stan Meyers of RBD Inc., project manager for
the subdivision, the assumed imperviousness coefficient
utilized to size the subdivision retention ponds was 0.50.
The impervious coefficient for Tract A is 0.48, less than
the assumea value. calculated as follows:
landscaped area - 10,293 SF
roofs. walks, drives-_5.210 SF
total lot area - 15.503 SF
c = 10.293 (.25) + 5,210 (9.5) = 0.48
15,503
Runoff from the lot will be directed to Riva Ridge Road
and Riva Ridge Drive as per the approved plan. Therefore
the subject lot will be constructed according to the
approved plans and will not place an undo burden on
retention ponds.
Sincerely,
