PROJECT DESCRIPTION AND NATURE OF CONSTRUCTION
SITE LOCATION
The Trail Head Park (site) is located in Section 4, Township 7 North, Range 68 West of the 6th
Principal Meridian, in Larimer County, Fort Collins, Colorado. The address of the site is 3403
Yule Trail Drive Fort Collins, CO 80524. The site is bordered to the north by Yule Trail Drive and
Roaring Creek Drive, to the west by Wagon Trail Road, and to the east by Greenfields Drive.
Developed residential areas are to the north, south, east and west of the site. The property is owned
by the City of Fort Collins and is comprised of parcel numbers 8704324908 and 8704313901. The
approximate GPS coordinates for the site are 40.59776°N, -105.01475°W.
EXISTING SITE CONDITION
The site is approximately 6.26 acres of undeveloped property and has an existing percent
impervious of 12.1%. The existing site is made up of park vegetation and is approximately 95%
covered. The existing ground surface is relatively flat, generally sloping to the west at grades
ranging from 0.1% to 3.0%, with an area of steep slope down to the group of trees at the southeast
of the site.
This site was part of the master drainage plan for the Trail Head Property and is included in the
study performed by JR Engineering in 2004. While the site generally conforms to the existing
drainage report, the majority of stormwater runoff is conveyed via surface flow either to the west
into an existing quadruple curb inlet in Wagon Trail Road or to the north into Greenfields Drive
or Yule Trail Drive and conveyed to an existing curb inlet at Yule Trail Drive and Roaring Creek
Drive, with bypass flows continuing down Roaring Creek Drive to the quadruple curb inlet in
Wagon Trail Road. The inlets are conveyed to the public storm drain system to the west and
eventually to the existing Pond A per the existing drainage report.
There is no existing onsite detention for the site. Stormwater is conveyed via an existing storm
sewer system to existing detention Pond A located southwest of the site. Per the Drainage and
Erosion Control Report prepared by JR Engineering, the existing Pond A discharges south, under
E Vine Drive into an existing swale on the Witham property. Stormwater flows south towards the
Boxelder Creek and ultimately to the Cache La Poudre River.
The site is comprised of three soil types: Fort Collins Loam, Nunn Clay Loam, and Satanta Loam.
All three soils hydrologic soil group C and are considered well-drained. From the geotechnical
report dated December 30, 2019 the soil is mainly sandy clay. Groundwater was encountered at
28 ft to 30 ft below the ground surface. The rainfall erodibility is K=0.24 for type C soil and will
cause rilling and gulling over longer distances and steeper slopes
PROPOSED CONSTRUCTION ACTIVITIES
In general, the proposed redevelopment of the site consists of utility service connections, overlot
grading, paving of sidewalks, play areas and building construction.
Trail Head Park - Erosion Control Report Page 3 of 7
POTENTIAL POLLUTANT SOURCES
DISTURBED & STORED SOILS
The total disturbed area will be approximately 5 acres. Soil stockpiles should be kept below the
locally mandated maximum height of 10 feet and surrounded with sediment control devices. If the
storage of these soils occurs over a period greater than 30 days, then consider temporarily seeding
the soil to minimize soil loss to wind and water erosion.
VEHICLE TRACKING OF SEDIMENTS
The existing site is undeveloped. A temporary stabilized stone pad and/or Trackout Plate (Vehicle
Tracking Control pad, VTC) will be provided at points of ingress and egress onto the unpaved
area. The VTC is designed to reduce the amount of mud transported onto the public roads by
construction traffic. If the site is extraordinarily muddy, then consider designating an area to wash
construction vehicles before they leave the site and enter the public right-of-way. A best
management practice (BMP) such as this is a good way to avoid the costs associated with street
cleaning or accidentally discharging large amounts of sediment into other storm drain systems.
When in doubt, choose methods that prevent pollution rather than ones that force clean-up at the
downstream end just before the stormwater enters the receiving waters. In other words, the most
efficient construction site BMPs are those that prevent erosion from happening.
MANAGEMENT OF CONTAMINATED SOILS
There are no known, existing contaminated soils on site. If contaminated soils are found, the
contractor shall report to the SWMP administrator.
LOADING AND UNLOADING OPERATIONS
The existing entrance to the site is not currently paved and loading/unloading activities will occur
within the site where a temporary gravel staging area will be provided.
OUTDOOR STORAGE OF MATERIALS
Materials storage, waste disposal, and vehicle maintenance and fueling can occur within an
enclosed and secure area.
BULK STORAGE OF MATERIALS
Bulk liquids may be stored on site and should be stored in a secondary containment area with a
fence so that if a spill were to happen the contents would pool in the containment area and prevent
it from entering stormwater runoff.
VEHICLE EQUIPMENT AND MAINTENANCE
Materials should be stored and handled in covered areas to prevent contact with stormwater, and
chemicals should be stored within berms or secondary containment devices to prevent leaks and
spills from entering stormwater runoff.
SIGNIFICANT DUST GENERATING PROCESSES
Disturbed areas not yet ready to be seeded, landscaped, paved, or otherwise stabilized shall be
watered, or ripped as necessary to preclude visible dust emissions. Contractor shall make every
Trail Head Park - Erosion Control Report Page 4 of 7
effort to minimize particulate emissions from vehicles performing the work, including but not
limited to regular maintenance of construction equipment.
ROUTINE MAINTENANCE ACTIVITIES
Materials should be stored and handled in covered areas to prevent contact with stormwater, and
chemicals should be stored within berms or secondary containment devices to prevent leaks and
spills from entering stormwater runoff.
ON-SITE WASTE MANAGEMENT
Materials storage, waste disposal, and vehicle maintenance and fueling can occur within an
enclosed and secure area. The area can be enclosed with temporary fencing and accessed through
a gate with a lock.
CONCRETE TRUCK/EQUIPMENT WASHING
A concrete washout facility will be provided onsite. Properly wash out concrete trucks and other
equipment in a manner and location (a minimum of 50 feet away from any inlet structures) so that
the materials and wash water cannot discharge from the site, and never into a storm drain system
or stream.
DEDICATED ASPHALT AND CONCRETE BATCH PLANTS
There will be no dedicated batch plant on site.
NON-INDUSTRIAL WASTE MANAGEMENT
Garbage cans shall be located at break areas and portable toilets shall be provided if onsite
bathroom facilities cannot be used. Locate dumpsters and portable toilets away from drainage
courses (minimum 50 feet from any inlet structures) and stake down toilets to prevent tipping.
SAW CUTTING AND GRINDING
The surface being cut shall be wetted to prevent dust. To prevent slurry from entering stormwater
runoff and discharging from the site, the contractor should use the minimum amount of water
necessary to prevent dust. Cutting slurry should be collected via vacuum or allowed to dry out and
be swept up after cutting is finished.
OTHER NON-STORMWATER DISCHARGES
Records of spills, leaks, or overflows that result in the discharge of pollutants must be documented
and maintained. Record all spills that are responded to, even if they do not result in a discharge of
pollutants. Information that should be recorded for all occurrences includes the time and date,
weather conditions, reasons for the spill, etc. Some spills may need to be reported to immediately.
Specifically, a release of any chemical, oil, petroleum product, sewage, etc., which may enter
waters of the State of Colorado (which include surface water, ground water and dry gullies or
storm sewers leading to surface water) must be reported. More guidance is available on the web
at www.colorado.gov. The Division’s toll-free 24-hour number for environmental hazards and
chemical spills and releases is 1-877-518-5608.
Trail Head Park - Erosion Control Report Page 5 of 7
CONSTRUCTION CONTROL MEASURES
Vehicle Tracking Control (VTC): A stabilized construction entrance will be provided at Roaring
Creek Drive to minimize tracking of mud and sediment onto paved surfaces and neighboring
roadways. The construction access and parking will be graded and covered with a crushed stone
base course during construction. The VTC will be relocated with the construction access as
necessary.
Silt Fencing (SF) and Sediment Control Logs (SCL): Sediment control logs shall be installed with
respect to proposed drainage patterns. Sediment control logs shall be constructed along the
portions of the east, west, south, and north sides of the property and along any drainage areas
subject to erosion. The sediment control logs shall be installed at the downhill side of the existing
slopes across the site and at all point discharge areas where shown or not, sediment control logs
shall be maintained as needed throughout the construction process.
Inlet Protection (IP): Each inlet on the proposed storm sewer system will have a temporary inlet
sediment trap constructed around it. In paved areas, this trap consists of wire mesh socks, concrete
blocks, and/or screens to filter the storm runoff and allow any silt to settle out. In fields or
landscaped areas this trap consists of wire mesh socks.
Overlot Grading: All overlot grading in the non-irrigated areas will have the surface roughened
and will be permanently landscaped or temporarily seeded until the planned installations are
completed. Alternately, rough-cut driveways or proposed paved areas can be covered with a layer
of aggregate, road base or asphalt paving.
Dust Control Measures: Disturbed areas not yet ready to be seeded, landscapes, paved, or
otherwise stabilized shall be watered, or ripped as necessary to preclude visible dust emissions.
INSTALLATION AND REMOVAL SEQUENCE OF CONSTRUCTION MEASURES
Vehicle Tracking Control: VTC shall be installed prior to any construction activity, site excavation
or earthwork activities. VTC shall be removed once activities that require going from dirt to
hardscape are done for the site.
Silt Fencing (SF) and Sediment Control Logs (SCL): Sediment control logs shall be installed once
overlot grading is completed. The temporary sediment control logs will remain until the storm
sewer structures are completed and ground cover is effective.
Inlet Protection (IP): The inlet protection will be installed as the storm sewer structures are
constructed. Inlet protection will remain until the site has been restored.
Overlot Grading: All open areas will be treated within 14 days of completion of the overlot
grading. At the completion of the mass grading, all exposed soil areas will have the surface
roughened and planted with revegetation seed mix. Vegetation is to be maintained throughout
construction by the contractor until areas are permanently landscaped.
Trail Head Park - Erosion Control Report Page 6 of 7
Dust Control Measures: Dust control measures shall be provided as soon as soils are being
disturbed until the site has been restored.
PHASING
Construction Start Date: May 2020.
Overlot Grading: May 2020
Utility Construction: June 2020
Building Construction: June 2020
Paving: July 2020
Site Restoration: August 2020.
MAINTENANCE AND INSPECTION REQUIREMENTS
The erosion control measures will be inspected daily during construction by the contractor and
after each rain event. All inspections shall be documented and shall include the date of inspection,
any incidence of non-compliance, signed certification that the site is in compliance, and any notes,
drawings, maps, etc. pertaining to repairs. Copies of all documentation shall be distributed to
municipalities and owner on a regular basis as specified by owner. Silt fence and straw bale barriers
will be checked for undermining and bypass and repaired or expanded as needed. Sediment should
be removed from inlet filters and silt fencing before one half of the design depth has been filled.
Sediments deposited in the public rights-of-way will be removed immediately. The temporary
vegetation of bare soils will be checked regularly and areas where it is lost or damaged will be
reseeded. At minimum, the contractor or his agent shall inspect all BMPs every 14 days and after
significant precipitation or snow melt events. Installations and modifications as required by the
City of Fort Collins will be implemented within 48 hours of notification. Contractor shall remove
temporary erosion control measures and repair areas as required after vegetation is established and
accepted by owner and municipality.
FINAL VEGETATION AND STABILIZATION
Permanent landscaping will include sodding, seeding, trees, shrubs or other vegetative cover to
open areas. Native perennial seeding will be established in non-irrigated areas and sod or other
vegetative cover will be established in irrigated open areas. Final stabilization is reached when all
soil disturbing activities at the site have been completed, and uniform vegetative cover has been
established with a density of at least 70% of pre-disturbance levels or equivalent permanent,
physical erosion reduction methods have been employed. Final stabilization will be achieved using
sod, native seeding, permanent BMPs and other methods. The contractor will be responsible for
final stabilization
Trail Head Park - Erosion Control Report Page 7 of 7
SEQUENCE OF CONSTRUCTION ACTIVITIES
Construction Sequencing: (Detailed construction sequencing to be determined by the contractor)
1. Installation of temporary erosion and sediment control measures.
This includes all sediment control logs, rock socks, erosion control blankets, and silt fence
where all land disturbing activities will occur.
2. Sequence of all land disturbing activity.
Overlot grading in preparation for the pouring of new sidewalks will occur early in the
construction schedule. Additional land disturbance will occur around the site for utility
installation and the construction of the new structures.
3. Drainage facility construction.
No new drainage facilities are proposed for this project.
4. Sediment basins, temporary channel stabilization.
Sediment control logs or erosion control blankets will be installed on the perimeters of the
vegetated grass buffers on the north and west sides of the site.
5. Seeding
All disturbed areas will be seeded upon completing of finish grading. Refer to the landscape
plans for detailed planting and seeding schedule.
6. Mulching.
Spread straw mulch uniformly over seeded areas at a rate of 90 lbs per 1000 square feet of
ground. No more than 25% of the ground should be visible. Crimp or pinch mulch into
soil 2-4 inches by using either a mulch anchoring tool, a farm disk operating on the contour
of the slope, or by cleating with bulldozer tracks operating up and down the slopes (to
prevent tracks from forming gullies).
7. Required maintenance activities (e.g. after-storm checks of all BMPs, etc.).
All temporary sediment control BMPs shall be inspected after each rain event to ensure
proper protection and to determine if cleaning is necessary. Final cleaning of all storm
facilities shall be provided upon final stabilization of site.
