RE: Erosion Control Plan for
New Fort Collins High School
Dear Kathy:
Enclosed fine the Erosion Control Report and Plan for the above
referenced project. As mentioned during various conversations
with personnel from our office, we are proposing to use a Soil
Sealant on parking lots and access roads in the project. These
areas will be finished to subgrade and treated with this emulsion
per the Specification which is included in Appendix B for your
review.
If you have any questions or require additional information,
please do not hesitate to call.
Very truly yours,
MELINE & IRELAN, I

The following report details erosion control measures for a 75
acre tract in east Fort Collins. The area is to be the site of
the New Fort Collins High School, and a portion of the proposed
City of Fort Collins Park. The development site is located at
the northeast corner of the intersection of Horsetooth and
Timberline Roads.
I. Site Characteristics
The existing site has been in agricultural use for a number of
years and irrigation ditches and laterals currently cross the
area in numerous locations. The land tends to slope gradually
eastward to the Fossil Creek Reservoir Inlet Ditch.
The Site is currently covered by wheat stubble. The crop was
harvested in late summer of 1992 and had been irrigated in the
spring. The wheat stubble is well established and will help to
reduce erosion hazards until overlot grading begins in November
of 1992.
Currently, the property is bordered on the east and north sides
by open agricultural land. Poudre River Power Authority (PRPA)
and National Cash Register (NCR) are west of the site, across
Timberline Road. The Dakota Ridge housing development on the
east end of the school site, is in the preliminary phases of
overlot grading and houses will appear in the spring of 1993.
The Fox Meadows subdivision is located south of the school site.
Parcels to the north are owned by W. W. Reynolds and current
plans call for single and multifamily units to begin construction
within the next few years.
The erodibility maps of Fort Collins show the proposed
development site to be within the "moderate" zone for wind and
rainfall erosion potential.
This projept_has._:a construction period of approximately 'two and
one-half years. The overlot grading is scheduled to begin in
November of 1992. A large part of the erosion control measures
planned for the site will be installed under Bid Package No. 1
"Demolition and Overlot Grading". The only temporary measures
that will depend on another contract are installation of the
gravel inlet filters. These filters will be installed after the
construction of the storm sewers which will occur under the
Utilities Bid Package beginning immediately following Overlot
Grading.
II. Erosion Control Measures
A. Structural Measures
Structural erosion control measures will consist mainly
of a sediment basin at the location of the future
detention pond. The overlot grading project will begin

NOW THERE'S A FAST, I1's
YOUR SOIL EXACT w
Erosion control doesn't have to be
a time-consuming operation.
Now you can cover acres in hours,
not days. You can lock down topsoil,
establish vegetation. And for a lot
less than the cost of other methods.
Soil Master WR`"' is the height of
technology in soil stabilization. Fast,
inexpensive and completely effective.
Spray application.
Soil Master WR is a blend of liquid
co -polymers (withTripolycate) -you
simply spray it on. Mixed with water,
it bonds soil to create a tough,
water-resistant membrane. Use it
as is, for treatment against erosion.
But you needn't stop there.
Thick or thin:
the choice is yours.
Soil Master WR is flexible -you
blend it just the way you want: Thick
will give you maximum control.
Thin it, and you have a tremendously
effective-tackifier-in hydroseeding
and mulching. Soil Master WR forms
a semi -permeable, transparent crust,
letting in just enough water to ensure
proper plant growth. Later, the same
crust provides a solid foundation
for plant roots.
Normal application rates are 50
to 100 gallons of Soil Master WR per
acre, mixed with 1,800 to 3,600 gal-
lons of water. You adjust the additive
and water dilution ratio to fit your soil
composition and application needs.
Dust abatement
and sand control.
Soil Master WR works just as well
against wind erosion. The crust seals
in even tiny particles of dust -and
helps you get a handle on wind-blown
dust and sand.
Any site, anywhere
in the world.
We've put Soil Master WR to the
test all over the world - Central and
South America, the Middle East, Mex-
ico, the Pacific Rim. It's the major
soil and slope stabilization method
used in the planned communities of
Mission Viejo and Aliso Viejo - two of
the largest developments in Southern
California. Whatever your environ-
ment, whatever your site condition,
we can customize Soil Master WR
to protect against post -fire erosion,
establish vegetation, allow water
infiltration -in short, to match your
specific need.

COST EFFECTIVENESS OF VARIOUS EROSION CONTROL PRODUCTS
ON 3:1 SLOPES
Products were tested from May,1987 through September,1987 in
Parker, Colorado. Note that all of the products tested are effective in

SOIL MASTER WR and hay (G) had a runoff value per inch of
precipitation far less than the control plot (C) or either of the hydrau-
lic mulches (paper and wood fiber - A and B). SOIL MASTER WR
works not only as a tackifier keeping hav in place but acts as a
viable sealer of soil particles when used done -see lower left corner
of the ESSI test plot. Also, note that when the geotextiles-jute
mesh (D). a coconut mat (E) and a polyester blanket (F)- became
saturated with water the resulting weight caused the wood test
frame to buckle.

with the construction of this basin and the irrigation
pond on the Fort Collins Park boundary. Sediments will
also be controlled by silt fences placed in major
drainage swales to slow and collect water borne
sediment loads traveling to the detention pond.
The construction contract has provisions for an erosion
control maintenance contract that will be in effect
during the entire construction period. Continuous,
periodic maintenance of erosion control measures will
be provided.
A Silt fence will encircle the irrigation pond,
reducing or eliminating the amount of sediments
entering the pond that will be used for on -site
irrigation demands as soon as it's completed. A silt
fence will be installed around the top soil storage
pile to filter water borne silts and protect the pile
from wind erosion, 1 foot wind berms will also be
installed. Gravel inlet filters will be installed at
all area inlets and curb inlets as soon as these
structures are completed under the utilities contract
in late December of 1992.
The south student parking lot will be paved with 4" of
recycled asphalt base course and will serve as the
contractors storage and staging area for the balance of
the project. All remaining access roads and parking
areas will be sealed with an emulsified soil sealant
(See Appendix B) after being brought to grade. Final
application of curb and gutter and asphalt surface will
be completed in October and November of 1993.
.A.temporary diversion ditch will be constructed on the
north and east sides of the 'commercial property, Sub -
basin B3, to channelize surface flows and direct -them ---_ _.
---- - ' to inlets protected by gravel filter barriers.
A temporary diversion ditch will also be installed
along the east side of Timberline Road to collect and
divert street flow from the crown of the road. This
ditch will continue north to the existing roadside
ditch at the northwest corner of the project. Off
site rainfall flowing onto the site at the northwest
corner of the project will be collected by a diversion
ditch paralleling the south side:of proposed Vermont
Drive approximately 800 feet and daylight east of the
three 'foot high berm, as shown on the Erosion Control
Plan.

B. Vegetative Measures
Vegetative erosion control measures will consist
primarily of the application of hay/straw mulch applied
at the rate of 2 tons per acre and crimped to all
landscape areas of the project. Mulching will be part
of the Demolition and Overlot Grading Contract and will
be implemented immediately after the areas are at
finished grade.
r
The east Campus and Soccer fields, sub -basins Al, A2,
A3, & A4 will be treated with 4 inches of topsoil
disked in plus 4 inches of topsoil to finished grade.
These areas will be seeded with Bluegrass Mix A (See
Table 1).in May 1993 after installation of the
irrigation system under the Landscaping and Irrigation
Contract.
The remaining landscape areas of West Campus which
includes berms, planters and building perimeter will be
finished to subgrade and treated with hay/straw mulch
and seeded with,0ats as a temporary cover crop. These
areas will.receive'topsoil and permanent seed planting
in Tall Fescue..seed or sod, Mix C (See Table 1) in July
of 1994. All',perennial grass seeding will occur after
the installation'bf',,'.the irrigation system under the
.Landscaping ..�and:.Irrigation Contract Phase B.
III. Seasonal Control and Maintenance
Overlot Grading of the site will take place in the fall of
1992. Wind Erosion.will most likely be the major.hazard
during this time frame.:, Measures to mitigate windborne
.sediments.will be�tlie application of soil.sealants.:and
-hay/straw mulch to all areas outside of the physical
building envelope. ;,These measures will .be completed--r. -----
�immediately following overlot grading and are included 'in
..Bid Package No. l._,:The time frame for the maximum rainfall
erosion hazard occurs in'the spring.
The project schedule calls for all erosion control measures
to be fully established by late February of 1993. This
includes all storm sewer inlet filters, silt fences,
sediment basins, soil sealants and vegetative control
measures.
Maintenance is anticipated to occur after every rainfall
event and will likely consist of cleaning and resetting of
silt fences, clearing of gravel filter barriers and some
spot maintenance of the grass stand or surface sealant on
the parking lots. The sediment pond will have to be cleaned
in mid -summer of 1993 and 1994 or until a full stand of
grass is established in the athletic fields.
