ADDENDUM TO STORM DRAINAGE REPORT
FOR COLLINDALE BUSINESS PARK
FOR THE AMENDED OVERALL DEVELOPMENT
OF COLLINDALE BUSINESS PARK
SITE DESCRIPTION
The Amended Overall_ Development Plan for Collindale Business Park includes
all land in the SET of the NE; and in the -NET of the SET of Section 31, Township
7 North, Range 69 West of the Sixth P.M., City of Fort Collins, County of
Larimer, State of Colorado, which lies -east of the Union Pacific Railroad and
north of the City of Fort Collins property known as Timberline Wetlands.
Included in the total site is that part of the Timberline Storage P.U.D. and
that part of the undeveloped Chandler property which drains south to the
Timberline Wetlands, as well as all lands of Chandler, Chadwick and the
previously developed Collindale Business Park area which flows northeast to
the existing detention pond at the northeast corner of the Collindale Business
Park.
PROPOSED DRAINAGE
We have included with this report a plan of the Collindale Business Park
area. This map was a part of the 1989 Collindale Business Park Drainage
Report,and all of the parcels draining northeast to the detention pond were
shown. The enclosed map is updated to include the Timberline Storage P.U.D.
and also the undeveloped Chandler property which drains south to the Timberline
Wetlands.
The Timberline Storage P.U.D. drainage report prepared in April 1993 by
Stewart & Associates, Inc -..shows that a north sub —basin of 0.75 acres will
drain to the north through a detention pond with a release rate of 0.32 c.f.s.
into Automation Way. This onsite detention quantity and flow release rate
into Automation Way substant.ially complies with the requirements of the 1989
Collindale Business Park Drainage Report. The south sub —basin of 3.63 acres
will drain undetained into the Timberline Wetlands, with the appropriate erosion
control procedures being utilitized.
There are no development plans at this time for the remainder of the
Chandler property which will drain south into the Timberline Wetlands. At
the time that development is proposed for this remaining land, a detailed
drainage plan and report_ shall be prepared, and onsite detention shall be
required if the developed imperviousness is greater than that provided for
in the Fox Meadows Master Plan.
All that part of the Amended
Business Park which drains to the
patterns and quantities shown in
therefore, further development in
and with the City of Fort Collins
Control.
