Dear Bob:
Carpet Exchange P.U.D. is a proposed retail planned unit development
on the East side of South College Avenue just North of Fossil Creek
Parkway. It is located in the Fossil Creek Drainage Basin. The site
has a net area of 2.98 acres and a gross area of 3.67 acres including
a ten —foot wide dedication for South College Avenue and the right—of—way
for Snead Drive. The site is zoned BL — Limited Business. The site
slopes fairly steeply from North to South toward Fossil Creek. The storm
water runoff from South College Avenue will remain in the street. The
adjacent property on the South and East does not drain onto the proposed
P.U.D. The storm water runoff from the Fred Schmid Appl icance Store
on the North is detained and then discharged into Snead Drive at their
Southeast corner. Therefore, there is no offsite storm water entering
the ons i to property.
The Master Drainageway Planning Study for the Fossil Creek Drainage
Basin prepared by Simons, Li & Associates, Inc., and dated August 1982
does not require onsite storm water detention. The site will be graded
to carry the runoff from the front or west side of the building Southerly
on the surface of the parking area to the South property line and then
Easterly to Snead Drive. The East half of the building and the area
lying East of the building will also drain Easterly to Snead Drive.
The discharge from the Fred Schmid detention pond is 0.71 c.f.s.
The capacity of the gutter downstream is 14.4 c.f.s. It will carry
the 10—year storm without topping the curb. The storm water will be
carried under Fossil Creek Parkway in a storm drain to Fossil Creek.
Fossil Creek Parkway is proposed to be realigned. The storm drain will
be designed in conjunction with the realignment.
