Site soils are classified as: 5 - Aldenvood - Urban land complex - (Type C Soil) Proposed development includes 14 Cottage homes, walkways, landscaping and a parking area located at the southern end of the site. The drainage concept for this project consists of routing the developed runoff from paved surfaces within the site into a detention wet vault located under the ��arking area at the southern part of the site. The gross hydraulically-connected impervious area boundary created by tiiis project is 1'L,152 SF. See attached revised impervious area drawing. Referring to the subject attached drawing, this gross amount can be reduced the following areas: - 573 SF (Water feature), -1,803 SF (Paver Blocks), -2,451 (Covered �� Farking N.), -2,601 (Covered Parking S.) This reduces to 4,724 SF which is less than the 5,000 threshold. � � � �7� C: Il��eunicnis;md Scuineti�l[inie I)e.ktupJ:mc_Zinuurrm�an_I:jurkcik_Cnuatcs_Druin:�ec_Rcport_R[V ll;I I u;.�luc .�
