1 Introduction
The primary purpose of preparing and maintaining a stormwater management plan is to
improve the health and quality of the State's urban waterways. The preparation of and
adherence to this plan will aid in achieving this objective by establishing a program of
actions to be used during construction activities and describing stormwater management
controls and various Best Management Practices (BMPs) necessary to reduce erosion,
sediment, and pollutants in stormwater discharge.
The project will disturb more than one acre (~2.59 acres), which will require a Stormwater
Management Plan (SWMP) permit. Information concerning the State of Colorado General
SWMP permit are not included in the appendices of this report, but this document may be
used by the project’s contractor as a part of the required documentation for final permit.
1.1 Site Description
The 4.011-acre project site is located 0.3 mile east of the South Timberline Road and Kechter
Road intersection and approximately 450 ft north of Kechter Road right-of-way (Figure 1).
The Hill Single-Family project is lot 2 of Blehm Subdivision 2nd Filing, being a replat of
Lot 5, Blehm Subdivision in Fort Collins, Colorado. The lot was recently assigned an address
of 2336 Kechter Road but has not received a parcel number to date. The GPS coordinates for
the proposed home site are 40°30'44.59"N, 105° 1'59.16"W. The lot is bound by a Stetson
Creek PUD Second Filing concrete drainage channel and single-family residential lots to the
north, and urban estate residential properties to the south, west, and east. No existing
structures are located on site.
The site is located within the McClellands drainage basin. Historically, site stormwater has
drained with gentle slopes (1-2%) from the southwest to northeast into offsite flood irrigation
channels on the upstream edge of Blehm Subdivision Lot 6 to the east and conveyed north to
the Stetson Creek PUD Second Filing concrete drainage channel, which discharges into
McClellands drainageway ~350 ft to the east. Once within the McClellands channel, it flows
southeast ~1.5 miles to a water quality pond adjacent to South County Road 7. This pond
Hill Single-Family FDP210005 Section 1
2 | P a g e
releases into Fossil Creek Reservoir inlet channel and travels south ~1/3 mile to Fossil Creek
Reservoir.
Per the flood insurance rate map (Appendix A), the lot is located within Zone X. Zone X is
defined as an area of minimal flood hazard and does not have a base flood elevation
associated with it.
Figure 1: Vicinity map
The lot is undeveloped pastureland (0% imperviousness) with moderate vegetative ground
cover (~80% vegetation). One existing tree is located at the northeast corner of the property
and will not be disturbed during construction activities. Possible environmental impacts to
the site include disturbance of existing vegetation; however, the site will have permanent
vegetation replaced in all disturbed areas after construction activities have been completed at
project site.
Per the NRCS Soil Survey of Larimer County (Appendix B), the site consists of ~57% Fort
Collins loam and ~43% Nunn clay loam, which has a hydrologic soil group C classification.
Hill Single-Family FDP210005 Section 1
3 | P a g e
These soils are anticipated to have a slow infiltration rate when thoroughly wet and a slow
rate of water transmission. Additional soil characteristics are as follows.
The site’s erosion factor K ranges between 0.24 and 0.43. The higher the K factor, the more
susceptible the soil is to sheet and rill erosion by water. Based on the NRCS map, the
northern portion of the site (the low spot) is less likely to experience water erosion than the
southern portion.
This project site is in the 5 and 6 wind groups. Wind erodibility groups range from 1 to 8.
The higher the group number, the least susceptible the soils are to experience wind erosion.
According to soils report by others (EEC 2021), approximate high groundwater levels appear
to be ~6 ft below present site grades.
Since the irrigation water rights associated with the property were previously sold, there are
no non-stormwater discharges associated with the site.
No known riparian or sensitive areas are located on-site or close to project. Closest riparian
and wetland area identified by the Colorado Natural Heritage Program is Fossil Creek
Reservoir.
No known ground contamination on-site.
1.2 Nature of Proposed Construction Activity
Since the total disturbed area is ~2.61 acres, the property owner’s contractor must obtain a
Colorado Discharge Permit System (CDPS) Stormwater Discharge Associated with
Construction Activities General Permit. Construction activity will be typical of small
residential developments, as discussed below.
Soil Type Percent of Site Hydrologic

Fort Collins loam, 0 to 3 percent slopes 26.0% C 0.43 5
Fort Collins loam, 3 to 5 percent slopes 31.0% C 0.43 5
Nunn clay loam, wet, 1 to 3 percent slopes 43.0% C 0.24 6
Hill Single-Family FDP210005 Section 1

Proposed site improvements include a two-story house with basement, attached garage, a
gravel driveway with access off Kechter Road, and a detached barn. There will be minimal
concrete surrounding the house and barn. The homeowner intends to revegetate with native
plant material and turf. The gravel driveway and turnaround shall be made of compacted road
base material meeting Poudre Fire Authority standards.
1.3 Proposed Sequence of Major Activities
The project will be constructed in two phases with the following sequence of construction
activity related to the proposed erosion control plan (Appendix C).
1. Install and implement construction boundary erosion fence (silt fence) and vehicle
tracking control at the proposed driveway entrance off Kechter Road.
2. Clear, grub, and stockpile topsoil along proposed driveway limits. Implement soil
storage area sediment controls adjacent to proposed barn location.
3. Utility service line installation (water, gas, and electric).
4. Stormwater culvert installation (four total).
5. Install and implement erosion log inlet and outlet protection for stormwater culverts
(three total).
6. Grade and construct Kechter Road entrance and access road.
7. Install rock socks along access road drainage swale and Kechter Road drainage
swales.
8. Complete final site stabilization of all disturbed areas along access road from Kechter
Road to proposed house.
9. Install concrete washout adjacent to proposed barn location.
10. Barn construction.
11. Complete final grading, landscaping, and site stabilization around barn.
12. Remove stockpile storage area sediment controls and concrete washout adjacent to
barn.
13. Install stockpile storage area sediment controls and concrete washout adjacent to
proposed house location.
14. House construction.

5 | P a g e
15. Complete final grading, landscaping, and site stabilization adjacent to house.
16. Final stabilization of vegetation.
17. Remove all BMPs and complete final site cleanup.
1.4 Location of Potential Pollutant Sources
The property owner’s future contractor shall identify potential pollution sources and
implement BMPs to minimize the risk of pollution outside the construction area. Potential
pollution sources will generally be restricted to on-site locations and are discussed in detail
within Section 3.2.
Hill Single-Family FDP210005 Section 2

2 BMPs for Stormwater Pollution Prevention
2.1 Erosion and Sediment Controls
Structural Practices
Structural practices for the site will consist mainly of a concrete washout area, vehicle
tracking pad, rock socks along the flowline of the drainage swales, and silt fence, which are
described in detail within the following paragraphs. Detail drawings of these BMPs are
included in Appendix D. BMPs are expected to change as construction progresses and it is
the responsibility of the contractor to ensure appropriate BMPs are in place and/or removed
at the appropriate time in the construction sequence (Section 1.3). All temporary and
permanent erosion and sediment control practices must be maintained and repaired as needed
to assure continued performance of their intended function. All BMPs shall be inspected and
repaired or replaced as indicated in Section 5 and as required to satisfy the conditions of the
SWMP permit.
The concrete washout area is intended to contain washout liquids and solids resulting from
the cleaning of concrete trucks and pumps. Washouts should be placed near the area where
concrete is being poured for either the house or barn.
A vehicle tracking pad is intended to trap mud and sediment within coarse grain material and
provide clean access to public roadways. Wherever construction vehicle access routes
intersect paved public roads (Kechter Road), a vehicle tracking control pad shall be installed
to minimize the transport of sediment (mud) by runoff or vehicles tracking onto the paved
surface. Pads shall be maintained and refurbished when necessary, to obtain their intended
result.
Rock socks are intended to be installed along the flowline of site drainage swales. The rock
socks will control localized sediment loading during construction activities.
Silt fence will aid in the prevention of sediment leaving the site during a stormwater runoff or
wind event by collecting silt deposits along the fence line while still allowing storm water to
seep through. Silt fence shall be placed along the western access road boundary closest to
Kechter Road (Blehm Subdivision 2nd Filing, Lot 1) and at the northeast corner of the project
Hill Single-Family FDP210005 Section 2
7 | P a g e
site to prevent sediment transport. Silt fence shall be inspected and maintained regularly;
generally, every 2 weeks and after every rainfall event that produces runoff. Sediment must
be removed, and rocks replaced. Silt fence shall be installed prior to any work commencing
on-site.
Non-Structural Practices
If there are any low sloped areas exposed during land disturbing activity (stripping, grading,
utility installations, stockpiling, filling, etc.) they shall be kept in a roughened condition by
ripping or disking along land contours until mulch, vegetation or other permanent erosion
control is installed by contractor.
If there are any exposed steep sloped areas created during land disturbing activity (stripping,
grading, utility installations, stockpiling, filling, etc.) they shall have slope protection. The
contractor shall use a tracked vehicle to run perpendicular to the slope to inhibit rill/gully
erosion. The contractor may use other windrow-type methods, as necessary.
No soil shall remain exposed by land disturbing activity for >30 days. After 30 days,
temporary or permanent erosion control seed/mulch or landscaping is required to be installed
by contractor.
Additional Non-Structural Practices are strongly encouraged, such as minimizing soil and
vegetation disturbance, providing educational materials on disposal/recycling, spill
prevention / clean up, identification and elimination of illicit discharges, promotion of street
sweeping and the development of public education programs.
THE CONTRACTOR SHALL ADD ANY AND ALL BMP’S AND DETAILS
NEEDED FOR SEDIMENT/EROSION CONTROL.
Hill Single-Family FDP210005 Section 2

2.2 Materials Handling and Spill Prevention
Potential impacts from significant materials and their handling are included below.
Chemicals, cleaning substances, and petroleum products related to construction shall be
stored within the construction trailer during barn construction or inside the future barn during
the house construction phase. These areas will protect the chemicals from encountering
precipitation. No storage of these materials will be allowed outside.
Maintenance of equipment and refueling shall not take place on-site until the barn is
constructed. Once the barn is constructed, equipment maintenance and fueling may be
accomplished either in the barn or off- site. Absorbent (e.g., kitty litter) shall be stored in the
construction trailer or barn and immediately applied to any spill with the dry material being
disposed of properly and legally.
All construction waste shall be disposed of in available on-site dumpsters throughout the
workday. Liquid wastes will be hauled off-site and disposed of properly and legally.
Any cleaning or maintenance of small equipment will be required to be done within a
containment device (e.g., horse trough) and the liquid disposed of properly and legally.
In the event of any spill, the SWMP administrator shall be notified immediately.
Spills shall be broken into three categories. Their definitions and the procedures required to
address the spills are indicated below.

3 Stormwater Management Controls
3.1 SWMP Administrator
The local contact / SWMP administrator (Administrator) has yet to be determined for project.
Administrator will be responsible for developing, implementing, maintaining, and revising
the SWMP. Administrator will also be responsible for required inspections and coordinating
and documenting changes or repairs resulting from inspections. Administrator will be
responsible for SWMP training and enforcement aspects and will be the first point of contact
for any stormwater issues.
3.2 Identification of Potential Pollution Sources
The permit identifies the following potential project pollution sources that must be evaluated
for their potential contribution to stormwater discharge.
Disturbed and stored soil
Construction will require areas to be disturbed, exposing soil, during utility installation,
access road grading, and foundation construction as shown on approved project utility plans.
BMPs shall include rock socks along access road swale, inlet protection on proposed storm
drain flared end sections, minimizing disturbance of existing vegetation and hard surfaces,
and slope roughening and tracking of slopes after disturbance and prior to landscaping,
paving, or building by contractor.
Vehicle tracking of sediment
Construction will require the contractor and all subs to drive their vehicles on unpaved
surfaces to the proposed buildings and utility improvement locations. BMPs will include a
policy that vehicles must be clean prior to entering the site and, if they become muddy during
construction or earthwork activities, mud is to be removed from the vehicle by hand in an
area near the vehicle tracking pad prior to departing project site. Any soil tracked from the
project site is to be disposed of by sweeping or scraping the material off Kechter Road. Any
muddy vehicle will use the vehicle tracking pad prior to leaving the site.
Hill Single-Family FDP210005 Section 3
12 | P a g e
Management of contaminated soil
Soil borings completed by others do not indicate existing soil contamination on-site. If
contaminated soil is encountered, dispose of material properly and legally.
Loading and unloading operations
Contractor shall limit the number of large vehicle traffic onto and off of project site during
the process of unloading and loading operations of construction vehicles and project
materials.
Outdoor storage activities
Inert materials, such as wood and stone, are not pollutant sources and may be stored outside.
These materials will likely be covered with tarps or plastic, but they are not covered by the
permit.
Chemicals and petroleum products will be stored within either the construction trailer or
future barn. Cement and mortar bags (if stored outside) will be completely covered with
plastic to avoid contact with precipitation.
Vehicle and equipment maintenance and fueling
Vehicle maintenance and fueling are a necessary part of the construction process. No fuel
will be stored on-site unless it is located inside the future barn. If vehicle maintenance is
required, it will either take place off-site or inside the future barn.
Significant dust or particulate generating processes
To control dust or particulate generating processes, a water truck or similar watering device
will be always available on-site. Contractor shall adhere to City of Fort Collins Ordinance
No. 044 and must follow controls outline in the current City of Fort Collins Dust Prevention
and Control Manual.
Routine maintenance activities involving fertilizers, pesticides, detergents, fuels, solvents,
oils, etc.
Fertilizers and pesticides will not be used during construction activities. Any cleaning or
maintenance of small equipment will be required to be done within a containment device
(e.g., horse trough) and the liquid will be disposed of properly and legally.
Hill Single-Family FDP210005 Section 3
13 | P a g e
On-site waste management
Site construction will result in standard construction waste. A dumpster for trash and a
dumpster for bulk recycling will be made available on-site by the contractor. Waste will be
hauled to the dumpsters by hand or in loaders. Dumpsters will be hauled off as needed. No
construction waste will be left outside overnight without being in a dumpster. No
construction debris (including broken concrete) may be buried on-site.
Concrete truck/equipment washing
One mobile concrete washout will be provided on-site during each phase of construction
(two phases total). This will be used for trucks and for any masonry/concrete tools.
Dedicated asphalt and concrete batch plants
No dedicated asphalt or concrete batch plant is proposed on-site with this project.
Non-industrial waste sources
Potential non-industrial waste sources include worker trash and portable toilets. Contractor
will provide all necessary on-site waste management items to control non-industrial waste
sources associated with construction activities.
Saw cutting and grinding
One utility service connection is proposed within Kechter Road asphalt paving area.
Contractor shall perform asphalt saw cut and pavement repairs per current Larimer Urban
Area Street Standards. Approximate saw cut area is ~50 sf asphalt. No construction waste
from saw cutting activities shall be left outside overnight without being in a dumpster. No
construction debris (including broken asphalt and concrete) may be buried on-site.
Non-structural waste sources, such as worker trash and portable toilets
A trash dumpster will be available for construction trash and will be located near the
construction trailer and emptied weekly. Portable toilets will be staked on site near the
construction trailer.
Hill Single-Family FDP210005 Section 3
14 | P a g e
Other non-stormwater discharges
No other non-stormwater discharges not covered under the construction dewatering
discharges general permit known to be associated with proposed construction activities.
Other areas or operations where spills can occur
Potential areas where spills can occur include adjacent to concrete washout area. Contractor
will ensure concrete washout area is properly maintained during construction activities.

4 Final Stabilization and Long-Term Stormwater Management
Long-term erosion control for this site will be include established native vegetative cover,
landscaping, and xeriscaping around the completed site improvements (access road and
buildings).
All disturbed areas outside of proposed structures will either be paved with compacted road
base, seeded with upland mix, sodded, or mulched. See Appendix E for site and landscape
plan for reference.
4.1 City of Fort Collins Native Seed Mix Notes
1. Prepare soil as necessary and appropriate for native seed mix species through aeration
and addition of amendments, then seed in two directions to distribute seed evenly
over entire area. Drill seed all indicated areas as soon as possible after completion of
grading operations.
2. If changes are to be made to seed mix based on site conditions, then approval must be
provided by City environmental planner.
3. Appropriate native seeding equipment will be used (standard turf seeding equipment
or agriculture equipment shall not be used).
4. Drill seed application recommended per specified application rate to no more than ½
inch depth (or appropriate depth for selected species). For broadcast seeding instead
of drill seeding method, double specified application rate. Refer to native seed mix
table for species, percentages, and application rates.
5. Prepare a weed management plan to ensure that weeds are properly managed before,
during, and after seeding activities.
6. After seeding, the area shall be covered with crimped straw, jute mesh, or other
appropriate methods.
7. Where needed, temporary irrigation should be provided until see is established. If
irrigation is used, the irrigation system for seeded areas shall be fully operational at
the time of seeding and shall ensure 100% head-to-head coverage over all seeded
areas. All methods and requirements in the approved irrigation plan shall be followed.
8. Contractor shall monitor seeded area for proper irrigation, erosion control,
germination, and reseeding, as needed, to establish cover.
Hill Single-Family FDP210005 Section 4
16 | P a g e
9. The approved seed mix area is intended to be maintained in a natural like landscape
aesthetic. If and when mowing occurs in native grass seed mix areas, do not mow
lower than 6 to 8 inches in heigh to avoid inhibiting native plant growth.
10. Native seed area will be considered established with seventy percent vegetative cover
is reached with no larger than one-foot square bare spots and/or until deemed
established by City planning services and erosion control.
11. The developer and/or landscape contractor is responsible for adequate seedling
coverage and growth at the time of final stabilization, as defined by state and local
agencies. If stabilization is not achieved to the satisfaction of the agency, the
developer and/or landscape contractor shall be responsible for additional corrective
measures to satisfy final vegetative requirements for closeout.
4.2 Final Stabilization
Exposed dirt areas containing hardscapes, and buildings will prevent future erosion to those
areas and will be considered stabilized following final construction. All areas identified as
requiring permanent seeding in the landscape plan (Appendix E) will have the area amended
in accordance with City Municipal Code §12-132 and be seeded with upland mix (Figure 2)
based on the specifications listed in the landscape plan.
All seeded areas will be crimped and mulched within 24 hours after planting, in accordance
with project temporary and permanent seeding details and City of Fort Collins Erosion
Control Criteria. All mulch shall be mechanically crimped and/or have an adequate amount
of tackifier applied to the soil and mulch to provide quick and effective erosion control. The
use of crimped mulch or tackifier may require multiple re-applications if not professionally
installed or have weathered or degraded before vegetation has been established. Areas of
embankments having slopes greater than or equal to 3H:1V will be stabilized with an erosion
mat or approved equal to ensure seed will germinate on steep slopes.
No temporary irrigation system is proposed with project. Once planting is complete in
permanent seeding areas, all seeding will be monitored until site has reached a vegetative
cover (density) of at least 70%. Colorado Discharge Permit System (CDPS) general permit
for stormwater discharges associated with construction activities defines final stabilization as
follows (CDPS 2021).
Hill Single-Family FDP210005 Section 4
17 | P a g e
Final Stabilization is the condition reached when construction activities at the site have been
completed, permanent stabilization methods are complete, and temporary control measures
are removed. Ares being stabilized with a vegetative cover must have evenly distributed
perennial vegetation. The vegetation coverage must be, at a minimum, equal to 70 percent of
what would have been provided by native vegetation in a local, undisturbed area or adequate
reference site.
The site is anticipated to be seeded in the spring of 2022 and will be fully established in the
fall of 2023. Once vegetation has reached 70% density, and confirmed by City of Fort
Collins staff, the erosion control warranty period will begin. At this time, all stormwater
infrastructure will be cleaned of sediment deposits and remaining temporary erosion control
measures will be removed from project site.

Hill Single-Family FDP210005 Section 5
18 | P a g e
5 Inspection and Maintenance
Site inspections will be performed to effectively address maintenance, repair, and adequacy
of BMPs. The site inspections will be performed by the SWMP administrator or her designee
a minimum of once every 14 calendar days on active construction sites and within 24 hours
after a significant storm event (resulting in soil or wind erosion). As part of site inspections,
the inspector will keep documentation of all inspections and BMP maintenance, including
updated site maps indicating new BMPs or the removal of BMPs since the previous
inspection. Blank site maps will be utilized and will be redlined by SWMP administrator
throughout construction to note all BMPs, pollutant sources, storage locations, etc.
Any maintenance, repair, or necessary installation of BMPs not noted during the inspection
must begin immediately. The modifications shall be noted in the SWMP and action taken
because of the inspection shall be noted and certified on or attached to the original inspection
report. The date and time of repair or change (start and finish) will be required in report.
5.1 City of Fort Collins Standard Erosion and Sediment Control Notes
General Erosion Control Requirements
These notes are a summary for the legal requirements, that are set forth in the Fort Collins
Stormwater Criteria Manual (FCSCM), and that any conflict is resolved by the more
stringent requirement controlling.
1. The Property Owner, Owner’s Representative, Developer, Design Engineer, General
Contractor, Sub-contractors, or similar title for the developing entity (here after
referred to as the Developer) has provided these Erosion Control Materials in
accordance with Erosion Control Criteria set forth in the Manual as an attempt to
identify erosion, sediment, and other potential pollutant sources associated with these
Construction Activities and preventing those pollutants from leaving the project site
as an illicit discharge. Full City requirements and are outlined and clarified in the
Manual under Chapter 4: Construction Control Measures and should be used to
identify and define what is needed on a project.
2. The Developer shall make themselves thoroughly familiar with the provisions and the
content of the specifications laid out in the Manual, the Development Agreement, the

3. The Developer shall implement and maintain Control Measures for all potential
pollutants from the start of land disturbing activities until final stabilization of the
construction site.
4. The City Erosion Control Inspector shall be notified at least twenty-four (24) hours
prior to the desired start of any construction activities on this site to allow adequate
time for on-site confirmation (initial inspection which can take up to two business
days after receiving the request) that the site is in fact protected from sediment and
pollutants discharges off site. Please contact erosion@fcgov.com early to schedule
those Initial Erosion Control Inspections well in advance so that demolition, clearing,
grubbing, tree removal, and scraping may begin without delay. Failure to receive an
on-site confirmation before construction activities commence is an automatic “Notice
of Violation” and can result in further enforcement actions.
5. The Developer shall proactively provide all appropriate Control Measures to prevent
damage to adjacent downstream and leeward properties. This includes but is not
limited to: trees, shrubs, lawns, walks, pavements, roadways, structures, creeks,
wetlands, streams, rivers, and utilities that are not designed for removal, relocation, or
replacement in the course of construction.
6. At all times the Developer shall be responsible to ensure adequate Control Measures
are designed, selected, installed, maintain, repaired, replaced, and ultimately removed
in order to prevent and control erosion suspension, sediment transportation, and
pollutant discharge as a result of construction activities associated with this project.
7. All applicable Control Measures based upon the sequencing and/or phasing of the
project shall be installed prior to those construction activities commencing.
8. As dynamic conditions (due to the nature, timing, sequence, and phasing of
construction) in the field may warrant Control Measures in addition, or different, to
what is shown on these plans, the Developer shall at all times be responsible to
implement the Control Measures that are most effective with the current state and
progress of construction. The Developer shall implement whatever measures are
determined necessary, and/or as directed by the City Erosion Control Inspector. The
Developer shall insure that all Erosion Control Plans (Maps) or SWMP documents
are updated to reflect the current site conditions, with updates being initialed and
dated. These site inspections and site condition updates shall be made available upon
request by the City.
9. All listings, provisions, materials, procedures, activities, site work and the like
articulated in this or other written site-specific documents (Including but not limited
to the erosion control reports, development agreements, landscape, and drainage
materials) shall meet or exceed the most restrictive language for City, County, State,
and Federal regulations with regards to erosion, sediment, pollutant, and other
pollution source Control Measures. The Developer shall be responsible to comply
with all of these aforementioned laws and regulations.

10. The Developer shall ensure that all appropriate permits (CDPS General Permit
Stormwater Discharges Associated with Construction Activity, Dewatering, Clean
Water Act, Army Corps of Engineers’ 404 Wetlands Mitigation Permit, etc.) have
been attained prior to the relevant activity has begun. These permits or copies shall be
made available upon request by the City.
11. The Developer shall furnish all conveniences and assistances to aid the Erosion
Control Inspectors of materials, workmanship, records, and self-inspections, etc. of
the Control Measures involved in the construction activities.
12. The Developer shall request clarification of all apparent site construction issues that
may arise due to inconsistencies in construction plans for the site or site conditions
around the selected Control Measures by contacting the Erosion Control Inspector.
The Erosion Control Inspector will not be responsible for any explanations,
interpretations, or supplementary data provided by others.
13. All Control Measures shall be installed in accordance with the Manual.
14. The City reserves the right to require additional Control Measures as site conditions
warrant, to the extent authorized by relevant legal authority.
15. As with any construction standards, occasions may arise where the minimum erosion
control standards are either inappropriate or cannot be justified. In these cases, a
variance to these standards may be applied for pursuant to the terms, conditions, and
procedures of the Manual.
16. Inspection. The contractor shall inspect site pollutant sources and implement Control
Measures at a minimum of once every two weeks during construction and within 24
hours following a precipitation event. Documentation of each inspection shall be
recorded and retained by the contractor.
17. All temporary Control Measures shall be cleaned, repaired, or reconstructed as
necessary in order to assure continual performance of their intended function. All
retained sediments, particularly those on paved roadway surfaces, shall be removed
and disposed of in a manner and location so as not to cause their release into any
drainage way.
18. Any Control Measure may be substituted for another standard Control Measure so
long as that Control Measure is equal to, or of greater protection than the original
Control Measure that was to be used in that location. (ex. silt fence, for wattles, or for
compact berms) Wattle alone on commercial construction sites have shown to be an
ineffective substitute for silt fence or compact berms unless it is accompanied by a
construction fence to prevent vehicle traffic.
19. Any implementation or replacement of existing Control Measures for a non-standard
control, or alternative Control Measure, shall require the review and acceptance by
the City erosion control staff before the measure will be allowed to be used on this
project. These Control Measures’ details shall be submitted, reviewed and accepted to
Hill Single-Family FDP210005 Section 5
21 | P a g e
be in accordance with the Erosion Control Criteria based upon the functionality and
effectiveness in accordance with sound engineering and hydrological practices
Land disturbance, Stockpiles, and Storage of Soils
20. There shall be no earth-disturbing activity outside the limits designated on the
accepted plans. Off road staging areas or stockpiles must be preapproved by the City.
Disturbances beyond these limits will be restored to original condition.
21. Pre-disturbance vegetation shall be identified, protected, and retained wherever
possible. Removal or disturbance of existing vegetation shall be limited to the area
required for immediate construction operations, and for the shortest practical period
of time. This should include sequencing and phasing construction activities in a way
so that the soil is not exposed for long periods of time by schedule or limit grading to
small areas. This should also include when practical advancing the schedule on
stabilization activities such that landscaping takes place shortly if not immediately
after grading has occurred. Vegetation efforts shall start as soon as possible to return
the site to a stabilized condition. Sensitive areas should avoid clearing and grading
activities as much possible.
22. All exposed soils or disturbed areas are considered a potential pollutant and shall
have Control Measures implemented on the site to prevent materials from leaving the
site.
23. All soils exposed during land disturbing activity (stripping, grading, utility
installations, stockpiling, filling, etc.) shall be kept in a roughened condition at all
times by equipment tracking, scarifying or disking the surface on a contour with a 2
to 4 inch minimum variation in soil surface until mulch, vegetation, and/or other
permanent erosion control is installed.
24. No soil stockpile shall exceed ten (10) feet in height. All soil stockpiles shall be
protected from sediment transport through the use of surface roughening, watering,
and down gradient perimeter controls. All soil stockpiles shall be protected from
sediment transport by wind in accordance with Municipal Code §12-150. All
stockpiles shall be flattened to meet grade or removed from site as soon as practical,
and no later than the completion of construction activities or abandonment of the
project. All off-site stockpile storage locations in City limits shall have a stockpile
permit from the City Engineering Department prior to using the area to store material.
If frequent access from hardscape to the stockpile is needed a structural tracking
Control Measure shall be implemented.
25. All required Control Measures shall be installed prior to any land disturbing activity
(stockpiling, stripping, grading, etc.). All of the required erosion Control Measures
must be installed at the appropriate time in the construction sequence as indicated in
the approved project schedule, construction plans, and erosion control report.
26. All inlets, curb-cuts, culverts, and other storm sewer infrastructure which could be
potentially impacted by construction activities shall be protected with Control
Hill Single-Family FDP210005 Section 5
22 | P a g e
Measures. Material accumulated from this Control Measure shall be promptly
removed and in cases where the protection has failed, the pipes shall be thoroughly
cleaned out.
27. All streams, stream corridors, buffers, woodlands, wetlands, or other sensitive areas
shall be protected from impact by any construction activity through the use of Control
Measures.
28. All exposed dirt shall have perimeter control. Any perimeter controls that drain off or
has the ability to be tracked onto the nearby hardscape shall have some form of
effective sediment control as the, or as part of the, perimeter control.
29. All exposed slopes should be protected. All exposed steep slopes (Steeper than 3:1
H:V) shall be protected from erosion and sediment transport through use of Control
Measures.
30. No soils shall remain exposed by land disturbing activity for more than thirty (30)
days after activity has ceased before required temporary seeding or permanent erosion
control (e.g. seed/mulch, landscaping, etc.) is installed. This is not just limited to
projects that are abandoned; this includes any project that is temporarily halted and no
immediate activity is to resume within the next thirty (30) days, unless otherwise
approved by the City Erosion Control Inspector. During a season when seeding does
not produce vegetative cover, another temporary erosion control shall be
implemented with or until temporary seeding or permanent erosion control can be
performed.
31. All individual lots shall have effective sediment controls located on the street side and
any down gradient side. Typically, most lots drain to the front yet on those cases
where houses are along a pond or drainage swale have the lot drain in a different
direction than the street, those individual lots will need protection on that down
gradient side to prevent sediment from leaving the lot. See the Individual Lot Details
for further clarification.
Vehicle Tracking
32. At all points where vehicles exit or leave the exposed dirt area on to a hardscape or
semi hardscape (concrete, asphalt, road base, etc.) shall have installed at least one
structural tracking Control Measure to prevent vehicle tracking. All areas not
protected by an adequate perimeter control shall be considered a point where vehicles
exit the site. Access points should be limited to as few entrances as possible (All
perimeter areas shall be protected from tracking activities).
33. In all areas that the structural tracking Control Measures fail to prevent vehicle
tracking, collection and proper disposal of that material is required. All inlets located
near access points and affected by tracking activities shall be prevented from the
introduction of sediment into the drainage system.
Hill Single-Family FDP210005 Section 5
23 | P a g e
34. City Municipal Code §20-62, among other things, prohibits the tracking, dropping, or
depositing of soils or any other material onto city streets by or from any source. City
Municipal Code, §26-498, among other things, prohibits the discharge of pollutants
on public or private property if there is a significant potential for migration of such
pollutant. Therefore, all tracked or deposited materials (intentional or inadvertent) are
not permitted to remain on the street or gutter and shall be removed and legally
disposed of by the Developer in a timely and immediate manner. Dirt ramps installed
in the curb-lines are not exempt to these sections of code and shall not be permitted in
the street right of way (public or private).
35. If repeated deposit of material occurs on a site, additional structural tracking controls
may be required of the Developer by the City Erosion Control Inspector.
Loading and Unloading Operations
36. The Developer shall apply Control Measure to limit traffic (site worker or public)
impacts and proactively locate material delivered to the site in close proximity to the
work area or immediately incorporated in the construction to limit operational impacts
to disturbed areas, vehicle tracking, and sediment deposition that could impact water
quality.
Outdoor Storage or Construction Site Materials, Building Materials, Fertilizers, and
Chemicals
37. Any materials of a non-polluting nature (steel, rock, brick, lumber, etc.) shall be
inspected for any residue coming off the material during routine inspection and will
generally be located where practical at least fifty (50) feet from any permanent or
interim drainage ways.
38. Any high environmental impact pollutant materials that have a high likelihood to result
in discharge when in contact with stormwater (lubricants, fuels, paints, solvents,
detergents, fertilizers, chemical sprays, bags of cement mix, etc.) should not be kept on
site where practical. When not practical, they should be stored inside (vehicle, trailer,
connex, building, etc.) and out of contact with stormwater or stormwater runoff. Where
not available, they shall be stored outside in a raised (high spots or on pallets), covered
(plastic or tarped), and sealed (leak proof container) in secondary containment location.
The secondary containment or other Control Measure shall be adequately sized,
located, where practical, at least fifty (50) feet from any permanent or interim
stormwater structures or drainage ways and shall be monitored as part of the routine
inspections.
Vehicle and equipment maintenance and fueling
39. Parking, refueling, and maintenance of vehicles and equipment should be limited in
one area of the site to minimize possible spills and fuel storage areas. This area shall
be located, where practical, at least fifty (50) feet from any permanent or interim
Hill Single-Family FDP210005 Section 5
24 | P a g e
stormwater structures or drainage ways and shall be monitored as part of the routine
inspections. All areas shall keep spill kits and supplies close.
Significant Dust or Particulate generating Process
40. The property must be actively preventing the emission of fugitive dust at all times
during construction and vegetation activities. All land disturbing activities that result
in fugitive dust shall be in accordance with Municipal Code §12-150 to reduce the
impacts to adjacent properties and community health. All required practices shall be
implemented and additional ones shall be followed. These practices include watering
the sites and discontinuing construction activities until the wind subsides as determined
by any City Inspectors.
Concrete truck / equipment washing, including the concrete truck chute and associated
fixtures and equipment
41. All concrete and equipment washing shall use structural Control Measures appropriate
to the volume of wash and frequency of use. These Control Measures shall be located,
where practical, at least fifty (50) feet from any permanent or interim stormwater
structures or drainage ways and shall be monitored as part of the routine inspections.
These areas shall be clearly identified and protected from any wash from leaving the
Control Measure. If frequent access from hardscape to the Control Measure is to occur,
a structural tracking Control Measure shall be implemented. These Control Measures
shall be frequently cleaned out.
42. The Developer is responsible for ensuring washing activity is taking place at the
appropriate Control Measure and site workers are not washing or dumping wash water
on to the dirt or other uncontrolled locations.
Dedicated Asphalt and concrete batch plants
43. Dedicated asphalt and concrete batch plants are not acceptable on construction sites
within the City of Fort Collins without an expressed written request and plan to reduce
pollutants associated with that type of activity and approval by the City of Fort Collins
specifically the Erosion Control Inspector. The Developer shall inform the erosion
control inspection staff of any dedicated asphalt, or concrete batch plants that is to be
used on site.
Concrete Saw Cutting Materials
44. Saw cutting material shall be in accordance with Municipal Code §12-150 for air
emissions and all water applications to the saw cutting shall prevent material from
leaving the immediate site and collected. These cutting locations, once dried, shall be
swept and scraped of all material and shall have proper and legal disposal.
Hill Single-Family FDP210005 Section 5
25 | P a g e
Waste Materials Storage and Sanitary Facilities
45. Trash, debris, material salvage, and/or recycling areas shall be, where practical, at least
fifty (50) feet from any permanent or interim stormwater structures or drainage ways
and shall be monitored as part of the routine inspections. These facilities should be
located out of the wind and covered as able. Where not able to cover, locating said
areas on the side of other structures to reduce exposure to winds, and follow maximum
loading guidelines as marked on the container. The Developer is required to practice
good housekeeping to keep the construction site free of litter, construction debris, and
leaking containers.
46. Sanitary facilities shall be prevented from tipping through the use of anchoring to the
ground or lashing to a stabilized structure. These facilities shall also be located as far
as practical from an inlet, curb cut, drainage swale or other drainage conveyances to
prevent material transport from leaving the local area. This consists of the facility being
located, where practical, at least fifty (50) feet from any permanent or interim drainage
ways.
Other Site Operations and Potential Spill Areas
47. Spills: For those minor spills that; are less than the State’s reportable quantity
for spills, stay within the permitted area, and in no way threaten any
stormwater conveyance, notify the City of Fort Collins Utilities by email at
erosion@fcgov.com or phone (970) 817-4770. For any significant, major, or
hazardous spills, notify the City of Fort Collins Utilities by phone only after
Emergency Response (911) has been notified and is on route, County Health
Department (LCDHE) has been notified through Larimer County Sheriff
Dispatch (970) 416-1985, and the State Spill Hotline Incident Reporting have
been contacted 1-877-518-5608. Written documentation shall be provided to
the City within 5 days of the event. All spills shall be cleaned up immediately.
48. Selection of “plastic welded” erosion control blankets shall not be used in
areas that wildlife, such as snakes, are likely to be located as these have
proven to cause entrapment issues.
Final stabilization and project completion
49. Any stormwater facilities used as a temporary Control Measure will be
restored and storm sewer lines will be cleaned upon completion of the project
and before turning the maintenance over to the Owner, Homeowners
Association (HOA), or other party responsible for long term maintenance of
those facility.
50. All final stabilization specifications shall be done in accordance with the
Manual, Chapter 4: Construction Control Measures.
Hill Single-Family FDP210005 Section 5
26 | P a g e
51. All disturbed areas designed to be vegetated shall be amended, seeded & mulched, or
landscaped as specified in the landscape plans within 14 working days of final grading.
52. Soil in all vegetated (landscaped or seeded) areas, including parkways and medians
shall comply with all requirements set forth in Sections 12-130 through 12-132 of the
City Municipal Code, as well as Section 3.8.21 for the City Land Use Code.
53. All seeding shall refer to landscaping plans for species mixture and application rates
and depths requirements.
54. All seed shall be drilled where practical to a depth based upon the seed type. Broadcast
seeding shall be applied at double the rate as prescribed for drill seeding and shall be
lightly hand raked after application. Hydroseeding may be substituted for drill seeding
on slopes steeper than 3(H):1(V) or on other areas not practical to drill seed and crimp
and mulch. All hydroseeding must be conducted as two separate processes of seeding
and tackification.
55. All seeded areas must be mulched within twenty-four (24) hours after planting. All
mulch shall be mechanically crimped and or adequately applied tackifier. The use of
crimped mulch or tackifier may require multiple re-applications if not properly installed
or have weathered or degraded before vegetation has been established. Areas of
embankments having slopes greater than or equal to 3H:1V shall be stabilized with an
erosion mat or approved equal to ensure seed will be able to germinate on the steep
slopes. During a season when seeding does not produce vegetative cover, another
temporary erosion control shall be implemented along with, or until, temporary seeding
or permanent erosion control can be performed.
56. The Developer shall warranty and maintain all vegetative measures for two growing
seasons after installation or until seventy percent (70%) vegetative cover has been
established, whichever is longer and meets all the Criteria outlined in the Fort Collins
Stormwater Criteria Manual Chapter 4: Construction Control Measures.
57. The Developer shall maintain, monitor, repair, and replace any and all applicable
Control Measures until final stabilization has been obtained. All Control Measures
must remain until such time as all upstream contributing pollutant sources have been
vegetated or removed from the site. When any Control Measure is removed, the
Developer shall be responsible for the cleanup and removal of all sediment and debris
from that Control Measure. At the point at which the site has been deemed stabilized
and verified by City Erosion Control Inspector, all temporary Control Measures can
then be fully removed. All measures shall be removed within 30 days after final
stabilization is achieved.
58. The responsible party shall maintain and keep current all payments or related forms of
security for the Erosion Control Escrow until 1) stabilization has been reached and 2)
Hill Single-Family FDP210005 Section 5
27 | P a g e
all Control Measures and/or BMPs have sediment materials collected and the Control
Measure removed from the site. At that time, the site will be considered completed and
any remaining Erosion Control Escrow shall be returned to the appropriate parties.
5.2 City of Fort Collins Erosion Control Security Calculations
The cost of erosion control for the site was compared to the cost to reseed the entire site and
the greater cost was used to establish the erosion control escrow amount. See Appendix F for
a break-down of the costs associated with seeding and erosion control.

6 SWMP Implementation
It is the responsibility of the project’s contractor to operate and maintain all facilities and
systems of treatment and control installed to achieve compliance with the conditions of the
SWMP permit. This includes, but is not limited to, effective performance, adequate funding,
plus adequate staffing and training.
All personnel on the construction site who will be able to affect or be affected by the SWMP
shall be trained prior to beginning work. These individuals will be given general orientation
information regarding the project and SWMP, shown where the SWMP is physically located,
the SWMP will be explained to them and available for their review, and the enforcement
policy will be reviewed. After this training, a certification that the employee or
subcontractor’s employee is familiar with the document and its procedures will be signed.
Throughout construction, as a part of a weekly safety meeting, the SWMP will be reviewed
with all attendees and any incidents discussed. All attendees shall be logged.

Description
Hydrologic soil groups are based on estimates of runoff potential. Soils are
assigned to one of four groups according to the rate of water infiltration when the
soils are not protected by vegetation, are thoroughly wet, and receive
precipitation from long-duration storms.
The soils in the United States are assigned to four groups (A, B, C, and D) and
three dual classes (A/D, B/D, and C/D). The groups are defined as follows:
Group A. Soils having a high infiltration rate (low runoff potential) when
thoroughly wet. These consist mainly of deep, well drained to excessively
drained sands or gravelly sands. These soils have a high rate of water
transmission.
Group B. Soils having a moderate infiltration rate when thoroughly wet. These
consist chiefly of moderately deep or deep, moderately well drained or well
drained soils that have moderately fine texture to moderately coarse texture.
These soils have a moderate rate of water transmission.
Group C. Soils having a slow infiltration rate when thoroughly wet. These consist
chiefly of soils having a layer that impedes the downward movement of water or
soils of moderately fine texture or fine texture. These soils have a slow rate of
water transmission.
Group D. Soils having a very slow infiltration rate (high runoff potential) when
thoroughly wet. These consist chiefly of clays that have a high shrink-swell
potential, soils that have a high water table, soils that have a claypan or clay
layer at or near the surface, and soils that are shallow over nearly impervious
material. These soils have a very slow rate of water transmission.
If a soil is assigned to a dual hydrologic group (A/D, B/D, or C/D), the first letter is
for drained areas and the second is for undrained areas. Only the soils that in
their natural condition are in group D are assigned to dual classes.

Aggregation Method: Dominant Condition
Aggregation is the process by which a set of component attribute values is
reduced to a single value that represents the map unit as a whole.
A map unit is typically composed of one or more "components". A component is
either some type of soil or some nonsoil entity, e.g., rock outcrop. For the
attribute being aggregated, the first step of the aggregation process is to derive
one attribute value for each of a map unit's components. From this set of
component attributes, the next step of the aggregation process derives a single
value that represents the map unit as a whole. Once a single value for each map
unit is derived, a thematic map for soil map units can be rendered. Aggregation
must be done because, on any soil map, map units are delineated but
components are not.
For each of a map unit's components, a corresponding percent composition is
recorded. A percent composition of 60 indicates that the corresponding
component typically makes up approximately 60% of the map unit. Percent
composition is a critical factor in some, but not all, aggregation methods.
The aggregation method "Dominant Condition" first groups like attribute values
for the components in a map unit. For each group, percent composition is set to
the sum of the percent composition of all components participating in that group.
These groups now represent "conditions" rather than components. The attribute
value associated with the group with the highest cumulative percent composition
is returned. If more than one group shares the highest cumulative percent
composition, the corresponding "tie-break" rule determines which value should
be returned. The "tie-break" rule indicates whether the lower or higher group
value should be returned in the case of a percent composition tie. The result
returned by this aggregation method represents the dominant condition
throughout the map unit only when no tie has occurred.
Component Percent Cutoff: None Specified
Components whose percent composition is below the cutoff value will not be
considered. If no cutoff value is specified, all components in the database will be
considered. The data for some contrasting soils of minor extent may not be in the
database, and therefore are not considered.
Tie-break Rule: Higher
The tie-break rule indicates which value should be selected from a set of multiple
candidate values, or which value should be selected in the event of a percent
composition tie.

Description
Erosion factor K indicates the susceptibility of a soil to sheet and rill erosion by
water. Factor K is one of six factors used in the Universal Soil Loss Equation
(USLE) and the Revised Universal Soil Loss Equation (RUSLE) to predict the
average annual rate of soil loss by sheet and rill erosion in tons per acre per
year. The estimates are based primarily on percentage of silt, sand, and organic
matter and on soil structure and saturated hydraulic conductivity (Ksat). Values of
K range from 0.02 to 0.69. Other factors being equal, the higher the value, the
more susceptible the soil is to sheet and rill erosion by water.
"Erosion factor Kw (whole soil)" indicates the erodibility of the whole soil. The
estimates are modified by the presence of rock fragments.
Factor K does not apply to organic horizons and is not reported for those layers.

Aggregation is the process by which a set of component attribute values is
reduced to a single value that represents the map unit as a whole.
A map unit is typically composed of one or more "components". A component is
either some type of soil or some nonsoil entity, e.g., rock outcrop. For the
attribute being aggregated, the first step of the aggregation process is to derive
one attribute value for each of a map unit's components. From this set of
component attributes, the next step of the aggregation process derives a single
value that represents the map unit as a whole. Once a single value for each map
unit is derived, a thematic map for soil map units can be rendered. Aggregation
must be done because, on any soil map, map units are delineated but
components are not.
For each of a map unit's components, a corresponding percent composition is
recorded. A percent composition of 60 indicates that the corresponding
component typically makes up approximately 60% of the map unit. Percent
composition is a critical factor in some, but not all, aggregation methods.
The aggregation method "Dominant Condition" first groups like attribute values
for the components in a map unit. For each group, percent composition is set to
the sum of the percent composition of all components participating in that group.
These groups now represent "conditions" rather than components. The attribute
value associated with the group with the highest cumulative percent composition
is returned. If more than one group shares the highest cumulative percent
composition, the corresponding "tie-break" rule determines which value should
be returned. The "tie-break" rule indicates whether the lower or higher group
value should be returned in the case of a percent composition tie. The result
returned by this aggregation method represents the dominant condition
throughout the map unit only when no tie has occurred.
Component Percent Cutoff: None Specified
Components whose percent composition is below the cutoff value will not be
considered. If no cutoff value is specified, all components in the database will be
considered. The data for some contrasting soils of minor extent may not be in the
database, and therefore are not considered.
Tie-break Rule: Higher
The tie-break rule indicates which value should be selected from a set of multiple
candidate values, or which value should be selected in the event of a percent
composition tie.

For an attribute of a soil horizon, a depth qualification must be specified. In most
cases it is probably most appropriate to specify a fixed depth range, either in
centimeters or inches. The Bottom Depth must be greater than the Top Depth,
and the Top Depth can be greater than zero. The choice of "inches" or
"centimeters" only applies to the depth of soil to be evaluated. It has no influence
on the units of measure the data are presented in.
When "Surface Layer" is specified as the depth qualifier, only the surface layer or
horizon is considered when deriving a value for a component, but keep in mind
that the thickness of the surface layer varies from component to component.
When "All Layers" is specified as the depth qualifier, all layers recorded for a
component are considered when deriving the value for that component.
Whenever more than one layer or horizon is considered when deriving a value
for a component, and the attribute being aggregated is a numeric attribute, a
weighted average value is returned, where the weighting factor is the layer or
horizon thickness.

Photograph RS-1. Rock socks placed at regular intervals in a curb
line can help reduce sediment loading to storm sewer inlets. Rock
socks can also be used as perimeter controls.
Description
A rock sock is constructed of gravel
that has been wrapped by wire mesh or
a geotextile to form an elongated
cylindrical filter. Rock socks are
typically used either as a perimeter
control or as part of inlet protection.
When placed at angles in the curb line,
rock socks are typically referred to as
curb socks. Rock socks are intended to
trap sediment from stormwater runoff
that flows onto roadways as a result of
construction activities.
Appropriate Uses
Rock socks can be used at the perimeter
of a disturbed area to control localized
sediment loading. A benefit of rock
socks as opposed to other perimeter controls is that they do not have to be trenched or staked into the
ground; therefore, they are often used on roadway construction projects where paved surfaces are present.
Use rock socks in inlet protection applications when the construction of a roadway is substantially
complete and the roadway has been directly connected to a receiving storm system.
Design and Installation
When rock socks are used as perimeter controls, the maximum recommended tributary drainage area per
100 lineal feet of rock socks is approximately 0.25 acres with disturbed slope length of up to 150 feet and
a tributary slope gradient no steeper than 3:1. A rock sock design detail and notes are provided in Detail
RS-1. Also see the Inlet Protection Fact Sheet for design and installation guidance when rock socks are
used for inlet protection and in the curb line.
When placed in the gutter adjacent to a curb, rock socks should protrude no more than two feet from the
curb in order for traffic to pass safely. If located in a high traffic area, place construction markers to alert
drivers and street maintenance workers of their presence.
Maintenance and Removal
Rock socks are susceptible to displacement and breaking due to vehicle traffic. Inspect rock socks for
damage and repair or replace as necessary. Remove sediment by sweeping or vacuuming as needed to
maintain the functionality of the BMP, typically when sediment
has accumulated behind the rock sock to one-half of the sock's
height.
Once upstream stabilization is complete, rock socks and
accumulated sediment should be removed and properly disposed.
