Mr. Basil Harridan
City of Fort Collins Utilities
P.O. Box 580
Fort Collins, CO 80522-0580
Dear Basil,
The following is the final drainage report for Poudre River Business Park, Second Filing
situate in the Northwest 1/4 of Section 18, Township 7 North, Range 68 West of the 6th P.M., Fort
Collins, Colorado.
The Internal Medicine Clinic has their office on the lot adjacent to the site on the West. The
clinic needs more parking and so is developing the new lot for parking only. A building may be
constructed on the site in the future. The two lots have a common driveway and a common drainage
outfall system.
The site is in the Cache la Poudre River Basin and contains 0.7391 acres. The site has some
temporary parking on the Westerly half of the lot. That part of the lot has a ground cover of recycled
asphalt. The Easterly half of the lot has a ground cover of grass and weeds. There are many small
volunteer Siberian Elm trees and other native plants on the site. The site has a slight ridge running
East-West through it. The slopes to the North and to the South are approximately 1.0%. The site
is bounded on the West by the existing Internal Medicine Clinic parking lot, on the North by the
Cache la Poudre River trail, on the East and South by undeveloped land.
There is an existing 15" R.C.P. storm drain on the South side of Poudre River Drive and an
18" R.C.P. crossing Poudre River Drive, as shown on Sheets 4 and 5 of the drainage plans. There
is an existing 24" A.D.S. storm drain from the North side inlet to the existing area inlet in the parking
lot and continues down to the Cache la Poudre River. The final drainage report for Poudre River
Business Park, First Filing is enclosed in the appendix of this report. The 100 year runoff rate on the
First Filing is 7.98 c.f.s. The 100 year runoff rate on the Second Filing is 5.92 c.f.s. The total 100
year runoff rate is therefore 13.9 c.f.s. The existing 24 inch, N-12 A.D.S. pipe will carry 23 c.f.s.
There may be future lots that will use the balance of the capacity of the existing storm drain. The
runoff rate to the existing 4.0 foot curb inlet on the North side of Poudre River Drive is 1.00 c.f.s.
from the West and 0.51 c.f.s. from the East for a total of 1.51 c.f.s. The inlet is in a sump condition
and the capacity of the inlet is 5.0 c.f.s.

Due to the site being adjacent to the Poudre River, there is no detention on the existing clinic
site and there is no detention planned on the new parking lot site.
The Poudre River Business Park Master Plan is divided into two basins. Basin I is the
Westerly half of the Master Plan and it drains to the existing drainage system. Basin II is the Easterly
' part of the Master Plan and it is undeveloped. This site is in Master Plan Basin I. The 100 year
runoff from Master Plan Basin I is 31.4 c.f.s. and the 2 year runoff is 9.6 c.f.s.. The capacity of the
24" N-12 A.D.S. pipe is 23 c.f.s.. Since the existing 24 inch ADS pipe has capacity for 23.0 c.f.s.,
and Poudre River Business Park First and Second Filings have a 100 year runoff rate of 13.9 c.f.s.,
there is capacity for 9.1 c.f.s. additional runoff There is approximately 16.9 c.f.s. runoff that will be
' developed in the 100 year event from the future lots in the Master Plan Basin I. On site storm water
detention could be required on future developments in order to use the existing 24 inch A.D. S. storm
drain.
' This site is divided into four sub -basins for the developed condition. Sub -Basin I is the
parking area which is being developed at this time. The area of Sub -Basin I is 0.479 acres and the
runoff rate for the two year storm is 0.92 c.f.s. and for the 100 year storm is 4.77 c.f.s. Sub -Basin
I drains to the existing area inlet and then to the Cache la Poudre River in the existing 24 inch A.D. S.
pipe.
Sub -Basin II contains 0.098 acres and is being left undisturbed at this time. It historically and
also will continue to flow on the surface to the Poudre River. The runoff rate for the two year storm
is 0.04 c.f.s. and for the 100 year stone is 0.18 c.f.s.
Sub -Basin III contains 0.313 acres and also is being left undisturbed at this time. It
' historically and also will continue to flow on the surface to the South. There will be no increase or
change in the runoff from Sub -Basin III. The runoff rate for the two year storm is 0.10 c.f s. and for
the 100 year storm is 0.46 c.f.s..
' Sub -Basin N contains 0.055 acres and is that part of the North half of Poudre River Drive
' that is having curb, gutter and walk constructed at this time. The runoff will flow to the existing curb
inlet on the North side of the street. The two year runoff rate is 0.12 c.f. s. and the 100 year runoff
rate is 0.51 c.f.s.
A water quality pond will be provided in the Northwest corner of the parking lot. A pit will
be constructed for the extended detention volume. The pit will spill the storm water volume, in
' excess of the extended detention volume, onto the driveway and the stormwater will flow to the
existing area inlet. A water quality riser pipe with water quality outlet holes will carry the extended
detention volume to the existing area inlet. The water quality plan is shown on sheets 4 and 5 and
' the detail of the water quality feature is shown on Sheet 7.
EROSION CONTROL: The site is in the moderate rainfall zone and in the moderate wind zone. A
' silt fence will be constructed along the North property line of the proposed parking lot prior to
beginning grading on the site. A strawbale area inlet filter will also be placed prior to beginning
grading on the site. Only the area in the parking lot will be disturbed. As soon as the rough grading
of the lot is completed, the curb and gutter will be constructed. As soon as the curb and gutter is
11
11
poured, the base material will be installed and then the asphalt can be laid. The only utility to be
installed is power to the area light. The irrigation system will then be installed.
The stormwater runoff calculations and the erosion calculations and the water quality
calculations are included as a part of this report. The grading plan and the drainage plan are also
included. Also the storm sewer plan and profile of the existing pipe to the Poudre River is enclosed.
The original drainage report for the First Filing is included in the appendix.
This drainage report and the design of the drainage system, were made in substantial
compliance with the City of Fort Collins Storm Drainage Design Criteria and Construction Standards.
If you have any questions during your review of this report, please call.
' Sincerely,
Richard A. Rutherford, P.E. L.S.

FINAL DRAINAGE REPORT
POUDRE RIVER BUSINESS PARK, FIRST FILING
STEWART & ASSOCIATES, INC.
December 7, 1988
I
I' Poudre River Business Park, First Filing is a 1.20 acre sibdivision
located on the East side of Lemay Avenue just South of the Cache la Poudre
' River. It is composed of a 0.69 acre lot for a medical office and Poudre
River Drive and Hoffman Mill Road.
' A small part of Poudre River Drive drains Westerly to Lemay Avenue
and then Northerly in the curb and gutter of Lemay Avenue to the Cache
la Poudre River. The balance of the dedicated streets and the lot will
' drain Easterly to a proposed storm drain along the Easterly line of Lot
1. The storm drain will have three curb inlets on Poudre River Drive
for on lot and street runoff. The drainage from the lot will drain
Easterly to an area inlet over the storm drain. Because of the close
' proximity to the Cache la Poudre River there is no onsite detention
provided.
There is an existing storm drain along the East side of Lemay Avenue -
that carries runoff from the Riverside Shopping Center to the Cache la
Poudre River. No storm water will be discharged into this storm drain.
There is no offsite storm water that enters Lot 1. No runoff from Lemay
' Avenue will enter the proposed project. There will be some storm runoff
from future lots on the South side of Poudre River Drive that will drain
into the street. The inlets on the South side of the street will be
' 6 foot inlets to allow the 100 year storm to enter the storm drain.
The area inlet in the parking lot will have an open area of 2.4 square
feet for the 100 year storm to enter the storm drain.
The runoff calculations and the grading plan are included as a part
of this report.
