PROJECT AND SITE ANALYSIS
Site Location
The project site is located in the northwest corner at the intersection of S. College Avenue and W.
Trilby Road, more specifically, Lot 2, C.O.L. College and Trilby Subdivision, situated in the Southeast
Quarter of Section 11, Township 6 North, Range 69 West of the 6
th
P.M., City of Fort Collins, County of
Larimer, State of Colorado.
Latitude, 40⁰ 29’ 45.50” N – Longitude, 105⁰ 04’ 40.56” W
Existing Site Description
The site is bounded by Southgate Church to the south, undeveloped fields to the west and north, and
S. College Avenue to the east. The existing site consists of a detention pond, paved parking and drive
areas, a naturally vegetated area, and an improved landscaped area. Generally, the naturally
vegetated area and the paved parking and drive areas drain to the detention pond either directly or
via an onsite storm sewer system, while, the improved landscaped area sheet flows directly to S.
College Avenue.
Soils Data / Groundwater
According to the Preliminary Geotechnical Engineering Report prepared March 5, 2003 by Terracon,
the site consists of sandy lean clay fill material, which correlates to soil Type ‘C’. Type ‘C’ soils have
low infiltration rates when thoroughly wetted. Anticipate moderate erosion potential from this soil.
The report also states that groundwater was encountered at eighteen feet below the existing site
grade. Based on these findings, dewatering is not anticipated to be required for the project.
Nature of Construction Activities
The proposed Ziggi’s Coffee development is 1.63 Acres and will consist of demolition activities,
building construction, approximately 492 square feet, concrete installation (drive-thru lane, curb and
gutter, sidewalk, patio, and bike rack area, and trash enclosure pad), ADA parking, and utility service
installation. Final Stabilization of the site will be achieved through permanent landscaping, pavement
and building areas. The following is a breakdown of the project area and raw earthwork volumes:
• Site area – 1.630 AC
• Area disturbed – 0.484 AC
• Export Import Volume – 59 C.Y. Cut and 97 C.Y. Fill
HCI Engineering, - 621 Southpark Drive, Littleton, CO 80120 - 303-979-3900
Page 4 of 18
Existing Vegetation
Existing ground cover in the proposed improvement areas generally consists of pavement and
improved landscaped areas. The correlating existing percent impervious is 68.1%. The middle third
section of Lot 2, originally planned for future building construction, is covered in natural vegetation
and exhibits approximately 70% vegetative ground cover.
Receiving Waters
Runoff from the site is generally collected by an existing onsite storm sewer system and conveyed
north to the onsite detention pond. Runoff from the improved landscaped area along the eastern
boundary releases offsite undetained, directly to S. College Avenue. This undetained runoff joins the
detained runoff in an existing inlet near the northeast corner the site. Runoff is then conveyed east by
a combination of storm sewer and open channels to Fossil Creek, approximately 1.35 miles east of the
site.
STORMWATER MANAGEMENT CONTROLS
Potential Sources of Pollution
The following are potential sources of pollution for this site.
1. All disturbed and stored soils:
The total area disturbed is 0.484 acres. Stockpiling is not anticipated to be needed for the
project based on earthwork volumes. The total area of disturbed soils exposed at one time
shall be kept to a minimum and shall be temporarily seeded if exposed for more than 30 days.
Sediment control logs shall be placed around site boundaries where runoff escapes offsite.
Inlet protection and curb socks shall be installed at existing downstream storm inlets.
2. Vehicle tracking of sediments:
Site access is limited to one location. Vehicle Tracking Control (VTC) shall be installed once
existing pavement is demolished in order to connect the paved drive lane to the Stabilized
Staging Area (SSA). Street sweeping shall be performed daily. Vehicle traffic shall only enter
disturbed areas based on required construction activities.
3. Management of contaminated soils:
To the best of our knowledge there are no existing onsite contaminated soils. Contaminated
soils from demolition or pavement activities shall be contained and properly disposed of.
Contractor shall follow the “Spill Response Plan” section of this report, should a spill occur
onsite.

occur onsite.
7. Significant dust or particle generating processes:
The total area of disturbed soils exposed at one time shall be kept to a minimum and shall be
temporarily seeded if exposed for more than 30 days. If disturbed soils begin to generate
significant amounts of dust, site watering shall be used. On May 3, 2016, the City of Fort
Collins passed Ordinance No. 044, 2016 (Fugitive Dust Ordinance), which amended Chapter 12
of the Code of the City of Fort Collins. Further information on the new requirements and Best
Management Practices (BMPs) can be referenced in the City of Fort Collins Dust Prevention
and Control Manual.
8. Routine maintenance activities involving fertilizers, pesticides, detergents, fuels, solvents, oils,
etc.:
Routine maintenance activities shall be confined to the SSA to the extent construction
activities allow. Contractor shall follow the “Spill Response Plan” section of this report, should
a spill occur onsite.
9. Onsite waste management practices (waste piles, liquid wastes, dumpsters, etc.):
Waste sources shall be confined to the SSA and must be located a minimum of 50 feet from
any inlet structures or watercourses. Contractor shall determine how demolition material is to
be disposed of as the project progress.
10. Concrete truck/equipment washing, including the concrete truck chute and associated fixtures
and equipment:
Concrete Washout Area (CWA) shall be accessible from the SSA and must be located a
minimum of 50 feet from any inlet structures or watercourses. No untreated water from
concrete activities is permitted to the leave site. Site boundaries near CWA shall be protected
with sediment control logs.

Spill Response plan
NOTE: IN CASE OF FIRE, EVACUATE ALL PERSONNEL FROM THE IMMEDIATE AREA. RENDER FIRST AID
TO ANYONE WHO IS INJURED, AND DIAL 911 IMMEDIATELY. TAKE APPROPRIATE STEPS TO PROTECT
HUMAN LIFE AND TO CONTROL FIRE FIRST. SPILL IS SECONDARY.
Upon detection of any spill, the first action to be taken is to ensure personal safety. All possible
ignition sources, including running engines, electrical equipment (including cellular telephones, etc.),
or other hazards will be immediately turned off or removed from the area. The extent of the spill and
the nature of the spilled material will be evaluated to determine if remedial actions could result in any
health hazards, escalation of the spill, or further damage that would intensify the problem. If such
conditions exist, a designated employee will oversee the area of the spill and the construction SWMP
administrator will be notified immediately.
The source of the spill will be identified and if possible the flow of pollutants stopped if it can be done
safely. However, no one should attend to the source or begin cleanup of the spill until ALL emergency
priorities (fire, injuries, etc.) have been addressed.
HCI Engineering, - 621 Southpark Drive, Littleton, CO 80120 - 303-979-3900
Page 11 of 18
Small Spills
Small spills (usually < 5 gallons) consist of minor quantities of gasoline, oil, anti-freeze, or other
materials that can be cleaned up by a single employee using readily available materials.
The following procedures should be used for clean-up of small spills:
1. Ensure personal safety, evaluate the spill, and if possible stop the flow of pollutants.
2. Contain the spread of the spill using absorbents, portable berms, sandbags or other available
measures.
3. Spread absorbent materials on the area to soak up as much liquid as possible and to prevent
infiltration into the soil.
4. Once liquids have been absorbed, remove all absorbents from the spill and place the materials
in a suitable container. On paved areas, wipe any remaining liquids from the surface and place
the materials in a storage container. Do not spray or wash down the area using water. For
open soil areas, excavate any contaminated soil as soon as possible and place in a suitable
storage container. All materials will then be transported off-site for disposal.
5. If immediate transfer and storage of the contaminated soil is not practical, excavate and place
the contaminated soil on a double sheet of 3-mil or higher polyethylene film. In addition, a
small berm should be formed around the outer edges of the soil stockpile, underneath the
polyethylene film, to ensure that contaminates are not washed from the site during
precipitation events and that materials do not seep through the berm.
6. Record all significant facts and information about the spill, include the following:
• Type of pollutant
• Location
• Apparent source
• Estimated volume
• Time of discovery
• Actions taken to clean up spill
7. Notify the SWMP Administrator of the spill and provide the information from item #6. The
SWMP Administrator will then contact City of Fort Collins.
Medium to Large Spills
Medium to large spills consist of larger quantities of materials (usually >5 – 25 gallons) that are used
on site that cannot be controlled by a single employee. Generally, a number of facility personnel will
be needed to control the spill and a response may require the suspension of other facility activities.
HCI Engineering, - 621 Southpark Drive, Littleton, CO 80120 - 303-979-3900
Page 12 of 18
The following procedure shall be used for the cleanup of medium to large spills:
1. Ensure personal safety, evaluate the spill, and if possible, stop the flow of pollutants.
2. Immediately dispatch a front-end loader or similar equipment to the spill and construct a berm
or berms down gradient of the spill to minimize the spread of potential pollutants. On paved
surfaces, portable berms, sandbags, booms, or other measures will be used to control the
lateral spread of the pollutants.
3. When the spread of the spill has been laterally contained, contact the SWMP Administrator or
designated facility employee and provide them information on the location, type, and amount
of spilled material, and a briefing on the extent of the spread and measures undertaken to
contain the contaminants.
4. Depending on the nature of the spill, mobilize additional resources as needed to contain the
contaminants.
5. Cleanup will commence when the lateral spread has been contained and the notification to the
SWMP Administrator has been made.
6. Freestanding liquid will be bailed or pumped into 55-gallon storage drums, steel tanks, or other
suitable storage containers. When all the liquid has been removed from the pavement or soil
layer, absorbents will be applied to the surface and transferred to the storage containers when
they have soaked up as much of the spill as possible.
7. On paved surfaces, the remaining contaminants will be removed to the extent possible, with
rags, sweeping, or similar measures. The area of the spill will not be sprayed or washed down
using water. And contaminant soaked materials will be placed into the storage containers with
the other absorbents.
8. The remaining contaminated soils will be excavated and loaded into a dump truck(s) for
disposal off-site at designated facility. If transport off-site is not immediately available, the
remaining soils will be stockpiled on a double thickness sheet of 3-mil or higher polyethylene
film. In addition, a small berm will be formed around the outer edges of the soil stockpile,
underneath the polyethylene film, to ensure that contaminants are not washed from the site
during precipitation and do not seep through the berm.
9. Record all significant facts and information about the spill, including the following:
• Type of pollutant
• Location
• Apparent source
• Estimated volume
• Time of discovery actions taken to clean up spill
HCI Engineering, - 621 Southpark Drive, Littleton, CO 80120 - 303-979-3900
Page 13 of 18
10. Provide the SWMP Administrator (or designated employee) with the information from Item #9.
The SWMP Administrator will then contact the City of Fort Collins.
