Mr. Glen Schlueter
Storm Water Utility
P.O. Box 580
Fort Collins, Colorado 80522
Dear Glen:
Mr. Lindsay Donaldson of URS Consultants, who is Project Manager for the
Poudre High School additions, has informed me that construction of the two
permanent detention ponds prior to completion of.the building structures is
impractical. The north pond is very close to the building, and the slope and
-depth of the pond relative to the finish building floor would make it impossible
to maneuver equipment and place scaffolding. The removal of sod and of pavement
on Impala Drive, which is necessary for construction of the south parking lot
on which the south detention pond is located, will not be done until the final
stages of construction.
The construction of building slabs for the two additions on the southeast
side of the building will cause 42000 square feet of presently sodded area
to be hard surfaced. The portion of the building slabs which is in addition
to the 42000 square feet will be over areas that are presently paved or
concrete, so it will not cause additional runoff.
We propose to construct a temporary detention pond, which will remain
in place during building construction, and which will. detain the additional
runoff generated by the 42000 square feet of new hard surface. The volume
of ponding required is 7486 cubic feet. The temporary pond will be located
within the construction fence at the low end of the construction site, so it
will pick up runoff from more than 42000 square feet. Any overflow will be
towards Impala Drive along existing flow paths and will not pose a problem.
The pond release will be through 4—inch plastic pipe and will flow onto Impala
Drive. The restricted opening will be 2.6 inch diameter.
A plan of this proposed temporary detention pond is enclosed along with
two calculations sheets. These temporary drainage facilities are in addition
to those proposed in our October 21, 1993 report for Additions to Poudre High
School.

FINAL STORM DRAINAGE AND EROSION CONTROL
ADDITIONS TO POUDRE HIGH SCHOOL
LOCATION OF SITE AND EXISTING CONDITIONS
Poudre High School- is located in the West z of the Southeast I of Section
9, Township 7 North, Range 69 West, of the Sixth P.M., City of Fort Collins, County
of Larimer, State of Colorado. The site is south of LaPorte Avenue and I mile
west of Taft Hill Road. The address is 201 North Impala Drive. The total site
area is approximately 39.326 acres, which consists of 3.302 acres of buildings,
13.759 acres of pavement and walks, and 22.265.acres of open area. The open area
consists of ball fields and lawn areas. Most of the ball field areas are grassed.
The 39.326 acre site does not include the Poudre School District R-1 administration
area which lies north of Poudre High School between LaPorte Avenue and the overhead
power transmission lines along the north edge of Poudre High School. The site
is located in the West Vine Drainage Basin.
A 1 inch =-100 feet scale drawing of the entire Poudre School District R-1
property is included with this report. This drawing shows all existing
improvements and topography of Poudre High School and also of the administration
area. We have indicated on this drawing the existing drainage paths of the Poudre
High School site.
The east portion of the school site drains along Impala Drive and through
the east parking lot to a point on Impala Drive located about 400 feet south of
LaPorte Avenue. The existing school building portion of the site has an internal
roof drainage system which carries runoff to an existing storm drain pipe which
runs around the west and north sides of the building and drains northeast into
the West Vine Drainage Basin. This storm drain is indicated on the enclosed 1"
= 100' plan.
There are no appreciable offsite flows onto the
site. The West Vine Drainage crosses the Poudre R-1
it does not impact the Poudre High School site. The
flood plain is shown on the enclosed 1" = 100' plan
= 60' utility and drainage plan.
PROPOSED SITE DEVELOPMENT
39.326 acre Poudre High School
administration
south line of
and also on the
area, but
the 100—year
included 1"
The 39.326 acre developed site will consist of 5.567 acres of buildings,
13.134 acres of pavement and walks and 20.625 acres of open area. The net increase
of impervious area will be 1.64 acres.
We are not changing runoff conditions on the west and northwest portions
of the site. The four small building additions along the west and northwest sides
of the building will replace existing asphalt pavement. The area where grass
will be replaced with buildings and pavement is on the east portion of the site.
This east portion consists of 13.42 acres which is shown as Basin Nos. 1, 2 and
3 on the included plan.
Additions to Poudre High School

DRAINAGE FACILITIES PROPOSED
Basin No. 1 has a total area of 6.79 acres. Most of the existing paved
parking on Basin No. 1 will remain as is, and although there will be some driveway
curbs placed on the existing pavement, the drainage will continue to flow to the
northeast corner of the existing east parking lot. The present flow, from this
northeast corner, goes north through an existing paved driveway to Impala Drive.
The new plan will remove the paved driveway and replace it with grass. A 4' wide
concrete drain pan will be installed to carry runoff from the northeast corner
of the parking lot to Impala Drive, and 4.2 acres of Basin No. 1 will drain through
this pan. The remaining 2.59 acres of Basin No. 1 is the grassed area and
adjoining driveways lying northeast of the school building. Runoff from this
2.59 acres flows overland to the northeast and onto Impala Drive. A 5—year storm
runoff can be carried in -the concrete pan before the water encroaches out of the
pan onto the grassed side slopes. There are no storm water detention facilities
proposed for Basin No. 1.
Basin No. 2 will have extensive building and'landscape changes, so we plan
to construct a detention pond in the landscaped area to collect runoff from the
pavement and buildings in Basin No. 2. Basin No. 3 will have new parking lot
construction, so a detention pond will be constructed on the new pavement. Outflow
from the detention ponds on Basin Nos. 2 and 3 will be carried in a pipe to the
new 4' concrete drain pan. A release rate of 0.5 c.f.s. per acre has been assumed
for Basin Nos. 2 and 3, which is conservative compared to the existing unrestricted
release from the entire site.
Roof drainage from the new buildings will be carried by interior downspouts
and then piped into dry wells outside the buildings. Overflow from these dry
wells will flow directly into the detention pond, either overland or piped. The
piped overflow will enter the area inlets on the upstream side of the restricted
pond outlets. These restricted outlet sizes are calculated on Sheet 7 of the
calculations. The restriction plate for the south pond will be placed over the
outlet pipe in the area inlet. The restriction plate for the north pond will
be placed horizontally in the area inlet box just above the 15—inch inlet and
outlet pipes to allow flow from the south pond to pass through.
The Poudre School District R-1 has been using dry wells for many years, and
the District prefers this way to dispose of minor flows. Our calculations do
not take into account any of the runoff which may be absorbed by the dry wells.
The attached calculation sheets show the additional volume of runoff generated
by the new impervious area, existing site runoff from Basin Nos. 1, 2 and 3, and
the runoff and proposed detention volumes on developed Basin Nos. 1, 2 and 3.
The included map of the building site shows the three basins and the proposed
drainage facilities and surface drainage.
An interior courtyard will be formed on Basin No. 2 by the new addition at
the front of the building. No roof runoff will be directed to the courtyard,
so it will receive only the water which falls upon it. An area inlet will be
constructed in the courtyard with an outflow pipe which will go into the north
detention pond. .

EROSION CONTROL
Poudre High School is located in a moderate rainfall zone and a low wind
erodibility zone. There will be no overlot grading on this project. The additions
along the north and west sides of the building will be over existing hard surface
areas, and the pavement will be removed and foundations placed immediately so
no bare soil will be left exposed. The additions at the front or east side of
the building require removal of sod for a new parking lot as well as removal of
sod and pavement for the new building foundations. In order to control sediment
from the exposed bare soil during the construction period while curbs and pavement
are being placed in the new parking lot and foundations are being placed for the
new building additions, it is proposed to install sediment filters in the detention
ponds, a silt fence along the northeast side of the building addition, and a gravel
filter where the runoff enters Impala Drive.
