RE: Glenwood Commons P.U.D. - Storm Drainage
Dear Bob:
This letter summarizes the approach M & I, Inc. has taken in devel-
oping a feasible Storm Drainage Plan for the Glenwood Commons P.U.D.
The grading and drainage plan was developed to confirm with the City
of Fort Collins Drainage Criteria.
The site has a substantial amount of trees and foliage. To preserve
these amenities for landscaping purposes existing elevations were
maintained wherever possible. The site will utilize parking lot
detention. Detention volume of the two detention areas amounts to
0.25 AC -FT. which facilitates the required capacity of 0.24 AC -FT.
The detention areas will outfall into a pipe system which will carry
the runoff northward and eventually empty in the storm drainage
system on CSU's property.
Outfall. from these areas will be restricted to the two year historic
outfall by means of a "Hydrobrake".This device (see attached brochure)
has received nationwide acclaim as a means of limiting outfall flow
to maximize the storm drainage system capacity. It has no moving
parts and requires virtually no maintenance.
I have enclosed the corresponding drainage calculations regarding
the conclusions of this report. If you have any questions or would
like clarification please contact me.
Very truly yours,
M & I, INC.

Dear Chuck:

At our April 3, 1,981 meeting concerning Glenwood Commons, the following items
were resolved:
1. The entrance drive from Shields Street to the parking area would be
reduced to a width of 14-feet. The centerline of this curb cut
shall align with the centerline of Springfield Drive. The 50-foot
setback of parking from Shields Street would be maintained. I have
checked with the Fire Authority and the above reduced width would be
acceptable.
2. The applicant agreed to include in the Subdivision Agreement that in
return for a future curb cut to Pitkin Street to the north, that the
curb cut to Shields Street would be redesigned at that time as an
egress -only situation.
Please feel free to contact me should you have any questions. Also, please
note that the April Planning and Zoning Board meeting has been rescheduled
for Thursday, April 30, 1981.
.ncerely,

RE: Glenwood Commons Storm Drainage Design
Dear Bob:
I am submitting this letter as a variance request regarding the storm
drain pipe sizing for the Glenwood Commons P.U.D. It is our recommend-
ation that a 12" RCP be used under the proposed parlsing area to pipe
runoff northward. We feel 12" pipe will be adequate in this instance
because:
1. The developer will maintain the installation.
2. Lower piping cost.
3. Lower hydro -brake cost since this cost is directly dependent on
pipe diameter.
If you have any questions or objections to this request, please notify
me.
Very truly yours,
M & I, INC.
