DRAINAGE AND EROSION CONTROL REPORT
PART OF LOT 12, TENNYSON HEIGHTS
EXISTING SITE:
The proposed site is the North 276 feet of Lot 12 of Tennyson Heights
Subdivision in the City of Fort Collins, County of Larimer, State of Colorado.
The site area is 0.85 acres which includes the south half of Cherry Street.
The site is bounded on the north by Cherry Street, on the south and east by
existing houses, and on the east by Putnam School. This project is a "fill
in" type project.
This site is located in the West Vine Drainage Basin and is partly located
in that basin's flood plain. Resource Consultants and Engineers, Inc. completed
a flood plain analysis report for this development. That report is included
with this report.
The existing site slopes south to north to a low hole just south of Cherry
Street. The south 80 feet is at a slope of 8.75%. The next 100 feet is at
a slope of 3.0% to the existing hole. The site is covered with existing grass
and weeds and several trees.
Offsite drainage flows onto this site from the west, south and east.
SIGN CRITERIA:
The rational method will be used to determine the developed site initial
and major storm runoff. Detention for the site will be based on the 100—year
storm less the allowed two—year historic release rate. The mass diagram will
be used to determine the required detention. All calculations and design
considerations are in accordance with the City of Fort Collins Design Criteria
Manual, except the historic 2—year storm will not be used for the release rate.
DEVELOPED SITE;
The developer proposes to build three four—plexes with off—street parking
provided on the west side of the site.. Runoff from this site for the most
part will be routed to the detention pond located in the parking lot, then
released at the two—year historic rate to a 3—foot concrete pan, and then to
Cherry Street.
There are two sub —basins onsite along with Cherry Street that cannot be
routed to the detention pond. Sub —basin "A" on the east will flow to a two —foot
wide concrete pan, then to Cherry Street. This pan will also route the offsite
flows east of the proposed project to Cherry Street that historically drained
onto this project. Sub —basin "B" on the west side of the site will flow to
a 3—foot wide concrete pan, then to Cherry Street. The concrete pan is required
for grade and also to handle runoff from the offsite basin that is south and
west of the project site. Runoff from this offsite area will be picked up
in an area inlet and then piped in a 15" A.D.S. double wall pipe to the 3—foot
pan. The City Storm Drainage Utility has agreed to construct this area inlet
and pipe to the 3—foot pan. All runoff directly south of this site will be
routed to the proposed detention pond and detained. This runoff is the same
amount that is running off our site undetained.
Part of Lot 12, Tennyson Heights
Page 2
The emergency spillway for this site is the access driveway.to Cherry
Street. Overflow will be to Cherry Street.
A variance is requested for the one —foot freeboard required. To construct
this site one foot higher could cause problems with the 100—year flow that
already crosses this site as shown on the City's West Vine Drive Drainage Basin.
This potential blockage is why the City made the developer flip the building
to the east side from the west side.
EROSION CONTROL:
The sequence of construction for this project is to construct the four—
plex foundations, then the sewer and water systems, then grading and gravel
base for the parking area, then asphalt and grading for the landscaping, and
then landscaping. Construction will start in the spring of 1994.
The construction sequence will keep the wind and rain erosion to a minimum.
After the pans have been constructed, a straw bale dike will be installed before
runoff reaches Cherry Street. The contractor shall be required to clean up
all mud and debris tracked onto paved streets.
This report and calculations are in compliance with the City of Fort
Collins cur -vent design standards and criteria.

Re: Tennyson Heights Floodplain Analysis
(RCE Job Number 93-224)
Dear Jack:
This letter summarizes our analysis of the floodplain in the West Vine basin near the intersection of Franklin
and Cherry Streets. This study was completed to support the proposed development on the North 276 feet
of lot 12 of Tennyson Heights. The purpose of the study was to determine the effects of the development
on the floodplain elevations. Presented below is a brief description of the development, a description of the
hydraulic analysis that was performed, and a summary of the results.
The proposed development is located on Cherry Street just east of Putnam Elementary School and near the
corner of Franklin Street (see attached vicinity map). The project proposes development of 6 apartment
buildings and a parking area within the remainder of the site being landscaped. Originally, the buildings
were to be built on the west side of the lot with the parking on the east side. In order to minimize the effects
on the floodplain, the site layout was modified so that the buildings are on the east side of the site and the
parking lot on the west side (see attached site plan).
The West Vine basin, where the site is located, drains area from the foothills on the west to Shields Street
on the east. The major drainage channel runs south of Vine Drive and north of Laporte Avenue. At the east
end of the basin, the historic channel has been developed and the capacity is limited. The City of Fort
Collins studied this basin and prepared a Major Drainageway Plan for the West Vine Drainage Basin dated
December 1980. The results of the basin study Indicated that the channel capacity near Vine Drive was
exceeded, and during a 100-year flood would split, and part of the floodwaters would flow along Cherry
Street. This floodplain along Cherry Street is what affects this site.
The attached map shows the existing floodplain in the area. As can be seen from the map, the proposed
development is on the edge of the floodplain. The floodplain was mapped utilizing the results of a hydraulic
model HEC-2 computer program for Water Surface Profiles. This program utilizes cross sections to
determine the elevation of water for flood flows. For this area, the floodplain was divided into two reaches:
Reach H and Reach G. The model cross sections were designated as H-1 through H-3 and as G-1 through
G-5. The cross section closest to the project was G-1. This cross section is located along the west property
line of the project.

Mr. Jack Blake 2 December 22, 1993
The City requirement for the development restricts development in the floodplain such that the development
must be elevated above the 100-year flood and must not adversely affect other property. Therefore, if the
fill is required on the site, the fill must not affect the flow of water such that the flood elevations are increased
on adjacent properties.
Utilizing this criteria, an analysis was performed'to determine if the proposed development would cause any
impact. This was done in two steps:
1. The model was modified to add another cross section that would be in the location of the proposed
buildings. The model was then run to determine a base condition to evaluated the effects of fill on
the site.
2. The model was run simulating the encroachment of the proposed development on the floodplain.
The original model was actually two data files, one for Reach G and one for Reach H. To evaluate the
effects of a project at the intersection of the two reaches, the data files were combined and the cross
sections renumbered. The cross sections were numbered 1.1 to 1.3 for Reach H and 2.1 to 2.5 for Reach
G. An additional cross section,.1.4, was added to simulate the site in more detail. Table 1 summarizes
the flood elevations that were computed based on the original and modified HEC-2 model for both reaches.
As can be seen when the two models were combined and the additional cross section inserted, the
computed flood elevations decreased slightly.

The Inserted cross section was developed from a combination of data taken from the topographic map and
from actual field -surveyed data for the street and site. This cross section was then modified to simulate the
construction of the buildings. The HEC-2 model was then run; the results are shown in the last column of
Table 1. The results of the analysis indicate that the development would cause no rise in the floodplain.
Enclosed is a disk containing the input and output for the HEC-2 model for both conditions of with and
without the project.

In conclusion, the proposed development as modified would have no adverse effect on the floodplain and
the structures on the site should be elevated with a first -floor elevation of 5022.1. This elevation is the base
flood elevation plus 1.5 feet of freeboard.
