Project Number: U14012
To Whom It May Concern:
United Civil Design Group, LLC. (United Civil), is pleased to submit this Stormwater
Management Plan (SWMP) for the Registry Ridge Seventh Filing site located in Fort
Collins, Colorado. This report outlines best management practices (BMPs) to be
implemented with the proposed construction, in order to minimize potential pollutants
in stormwater discharges.
We have prepared this report to accompany the Colorado Department of Public Health
and Environment General Permit for Stormwater Discharges Associated with
Construction Activity.
Please note that this document is intended to be a “living” document which should be
modified and updated through the course of site construction to accurately reflect site
conditions at all times. Pollutant sources should be continuously evaluated, BMP’s
selected, documented, implemented, and pollutant sources re-evaluated. As such, this
version of the SWMP was prepared to facilitate initial plan approvals and permitting,
but does not necessarily reflect the final version, or the transitions throughout the
construction process. It shall be the responsibility of the Construction Site Operator
and/or the permit holder (or applicant thereof) to ensure the plan is properly
maintained and followed. The Construction Site Operator or SWMP Administrator for

I. Introduction
A. SWMP Objective
The objective of this Stormwater Management Plan (SWMP) for Registry Ridge Seventh
Filing, is to identify the Best Management Practices (BMP’s) which, when implemented,
will meet the requirements of the Colorado Department of Public Health &
Environment, Water Quality Control Division. According to Appendix A of the State of
Colorado General Permit Application and Stormwater Management Plan Guidance for
Stormwater Discharges Associated with Construction Activity (6/2011), the SWMP goal is
to, “describe appropriate controls and measures to improve water quality by reducing
pollutants in storm water discharges and ensure compliance with the requirements of
the storm water permit. The SWMP must be completed and implemented at the time
the project breaks ground, and revised if necessary as construction proceeds to
accurately reflect the conditions and practices at the site.”
The SWMP is a “living” document which should be modified and updated through the
course of site construction to accurately reflect site conditions at all times. Pollutant
sources should be continuously evaluated, BMP’s selected, documented, implemented,
and pollutant sources re-evaluated (and the process continued). A current copy of the
SWMP shall be kept onsite at all times. A person familiar with the SWMP and on-site
construction activities and clean-up procedures should be designated as the SWMP
Administrator for the site. The SWMP Administrator will be responsible for, but not
limited to, inspections and inspection reports, personnel training, regulatory agency
contact, SWMP implementation and revisions, field notebooks, and record keeping of
employee activities, contacts, and notifications.
References are found in the Appendix regarding some of the requirements, restrictions,
and forms related to the SWMP.

Terracon, previously completed the geotechnical and groundwater investigations for the
project site and presented the results of this work in reports for both the Second and
Fourth Filings of Registry Ridge. According to these reports, there are sandy lean clay
soils overlying siltstone/claystone bedrock. Groundwater was observed at depths of
approximately 12 to 23 feet below ground surface and bedrock was encountered at
depths between 7 to 22 feet.
Stormwater Management Plan
Registry Ridge Seventh Filing
Fort Collins, CO
6 U14012-SWMP.docx
According to the NRCS Web Soil Survey, the site consists of Stoneham Loam, Nunn Clay
Loam, and Renohill Clay Loam (Hydrologic Soil Groups B, C, and D respectively). These
soils range from have “Moderate infiltration” (Hydrologic Soil Group B) to “Very slow
infiltration” (Hydrologic Soil Group D) ratings per the NRCS Web Soil Groups.
H. Location and Description of Potential Pollution Sources
This section focuses on the identification of the potential pollutant sources and briefly
discusses the Best Management Practices (BMPs) that will be used. More information
on the BMP’s utilized on this site is included in the next section “III. BMPs for
Stormwater Pollution Prevention”.
1. All disturbed and stored soils;
It is expected that there will be stockpiles of dirt on the site from the utility installations
and the foundation excavation. For this site, stockpiles should be located in areas
where Silt Fence or Straw wattles may be placed around the individual stockpiles to
contain the runoff (i.e. landscaped or disturbed earth areas).
2. Vehicle tracking of sediments
It is anticipated that the contractor will access the property from Bon Homme Richard
Drive and Enterprise Drive adjacent to each site area. A vehicle tracking control pad will
be required at each access location onsite during construction to reduce tracking
sediment onto the adjacent streets.
At the end of each workday, the Contractor shall sweep or scrape both Bon Homme
Richard Drive and Enterprise Drive of sediment that may have accumulated during the
workday.
3. Management of contaminated soils
There are not any known contaminated soils on the site. However, if the contractor
encounters contaminated soils during the construction process they should stop
construction immediately and notify the appropriate government authorities in
accordance with good construction safety and practice.
4. Loading and Unloading operations
Loading and unloading will take place on the site. Truck access should be limited to the
extent possible to locations within the disturbed limits of the project. BMP’s such as silt
fence in non-paved areas and rock socks in paved areas should be placed to keep
sediment from exiting the disturbed area limits, primarily towards the south and west as
these are the low side of the site.
Stormwater Management Plan
Registry Ridge Seventh Filing
Fort Collins, CO
7 U14012-SWMP.docx
5. Outdoor storage activities (building materials, fertilizers, chemicals, etc.)
Storage of onsite materials including building materials, fertilizers, waterline, and
sanitary sewer will be covered and placed on pallets to prevent direct contact with the
ground and potential surface runoff.
6. Vehicle and equipment maintenance
Vehicle and equipment maintenance should be performed offsite or onsite within an
area surrounded by silt fence or straw wattles. Vehicle and equipment maintenance
shall not happen along the adjacent public streets. At a minimum, all vehicle and
equipment maintenance shall be performed on the hard surface or gravel areas at least
50’ from any stormwater feature (i.e. inlet, storm sewer, concentrated runoff, swale,
etc.)
7. Significant dust or particulate generating processes
The Contractor shall comply with applicable air pollution control requirements of the
City of Fort Collins. The Contractor shall take appropriate actions to minimize
atmospheric pollution and take reasonable precautions which shall include, but not be
limited to:
1. The use of water for control of dusts for construction processes such as
demolition, grading, or the clearing of land.
2. Covering, at all times when in motion, open-bodied trucks transporting
materials likely to give rise to airborne dusts.
3. Require lower speeds for vehicles entering, exiting, and driving within the
project limits to minimize the amount of dust disturbed by moving vehicles.
8. Routine maintenance activities involving fertilizers, pesticides, detergents, fuels,
solvents, oils, etc;
Chemicals, fuels, lubricants, and paints stored on-site will be in water tight containers
and covered as necessary and stored in a bermed area, a storage building, or within a
vehicle to act as secondary containment.
9. On-site waste management practices (waste piles, liquid wastes, dumpsters, etc.);
1. Waste piles should be covered or surrounded by silt fence or straw wattles.
Liquid wastes should be collected and stored in covered containers and
disposed of properly.
2. Solid waste materials, including disposable materials incidental to the major
construction activities, will be collected in on site dumpsters. The containers will
be emptied periodically and trucked away from the site. Dumpsters should
have covers.
Stormwater Management Plan
Registry Ridge Seventh Filing
Fort Collins, CO
8 U14012-SWMP.docx
10. Concrete truck / equipment washing, including the concrete truck chute and
associated fixtures and equipment;
A dedicated concrete washout area is necessary for this project. The contractor shall
clean out equipment within the washout area so that runoff is not allowed to leave site
and enter the public streets or neighboring properties.
11. Dedicated asphalt and concrete batch plants;
There will not be dedicated asphalt or concrete batch plants on this site.
12. Non-industrial waste sources such as worker trash and portable toilets
Worker’s trash shall be disposed of in an onsite dumpster. The site should be free of
trash at the end of each working day.
Portable toilets shall be utilized by construction personnel and serviced regularly by a
commercial operator. They shall be located a minimum of 5 feet from the curb or 50
feet from inlets. If sanitary facilities are located on a paved surface, toilets shall be
equipped with a containment pan or a secondary containment BMP. Regardless of
location all portable toilets shall be anchored per manufacturer recommendations.
I. Non-Stormwater Components of Discharge
According to the Terracon reports, groundwater was observed at depths of
approximately 12 to 23 feet below ground surface. At these depths, it is possible that
groundwater may be encountered during construction. Where groundwater is
encountered during trenching or excavation operations, a temporary
sediment/retention basin should be constructed to store pumped dewatering flows.
The other non-storm water components of discharge include, but are not limited to,
water line flushing, irrigation to establish seeding, and watering for dust mitigation, and
compaction. It is important for the contractor to manage the runoff from these items
utilizing the BMP’s mentioned in this report (i.e. silt fence, straw waddles, concrete
washout areas, surface roughening, etc.).
J. Receiving Waters
The site lies within the Fossil Creek Basin. The vast majority of the proposed site will
drain via overland flow, grass lined swales and storm drains to the existing regional
pond located south of the site. Upon exiting the regional pond, runoff from the basin
empties into a tributary of Fossil Creek and ultimately drains to the Poudre River
through a series of inlets, culverts, and channels.

III. BMPs for Stormwater Pollution Prevention
A. Erosion and Sediment Controls
Once construction activity begins, Best Management Practices (BMP’s) intended to
contain sediment onsite must be constructed, inspected, and repaired as necessary.
Such controls must be functional before upslope land disturbance takes place. The
BMP’s will be installed as shown on the SWMP Map shown in Appendix A. They must be
supplemented as on-site experience proves necessary in order to control sediment,
pollutant discharge, and ensure public safety.
The following temporary and permanent BMP’s will be installed and maintained to
control on-site erosion and prevent sediment from traveling off-site during construction.
Temporary BMP’s
• Construction Fence is a temporary BMP. The contractor is to place construction
fencing around development as needed to limit access by construction equipment
and personal vehicles to designated areas of ingress and egress.
• Inlet Protection is a temporary BMP that helps prevent soil and debris from the site
from entering the storm drain inlets and usually consists of a sediment filter around
or upstream of the storm drain inlet. Inlet protection allows storm water to flow
into the drain but only after excess sediment has been filtered out. Inlet protection
will be used on existing and proposed storm inlets and will be installed at such time
as construction of the storm sewer system occurs. Inlet protection for this site will
consist of:
• Regular Meetings are a temporary and non-structural BMP. Regular meetings with
on-site workers including builders, suppliers, landscape personnel, etc. should be
conducted so that they are kept up to date with site standard operating procedures.
• Silt Fence is a woven synthetic permeable fabric that filters runoff. Silt fence is a
temporary barrier that is installed prior to earthmoving activities and is placed
downstream of areas where runoff from construction activities is expected to occur,
especially along the site perimeter to allow sediment to settle from runoff before
water leaves the construction site. Silt fences will be installed per manufacturer’s
recommendations. Silt fence encourages sheet flow and is not intended to be used
in areas of concentrated flow. If concentrated flow is encountered during the
placement of the fence, an alternative BMP shall be used and the SWMP should be
updated to reflect this change.
• Staging Areas will be provided during the construction process at least 100’ from
any storm water conveyance. Staging areas include locations for vehicle fueling,
Stormwater Management Plan
Registry Ridge Seventh Filing
Fort Collins, CO
10 U14012-SWMP.docx
concrete truck washout, material storage and transfer, equipment maintenance and
cleaning, and other construction activities. These areas will be maintained as
isolated locations that allow for contaminants to be concentrated and removed from
the site as necessary. Concrete washout areas shall be designed such that washout
water cannot leave the location, nor shall storm water runoff wash concrete from
the locations.
• Straw Wattles are a temporary BMP that are used for a variety of purposes. They
are used for inlet protection, curbside check dams, swale protection, at the bottom
of slopes, or the limits of property boundaries. They are easy to install and are
increasingly being used for Small Site SWMP’s. The straw wattles, which are meshed
netting “tubes,” filled with straw, excelsior, or coconut fiber. Wattles for swale
protection should be installed following rough grading of channel areas. Wattles
require proper installation and maintenance to ensure their performance.
• Rock Socks are a temporary BMP that are used for a variety of purposes. They are used for
inlet protection, curbside check dams, or at the limits of property boundaries. Rock socks
are wire meshed “tubes” filled with rocks. Rock Socks require proper installation and
maintenance to ensure their performance.
• Street Sweeping and Vacuuming removes sediment that has been tracked onto
roadways to reduce sediment transport into storm drain systems or a surface waterway.
This practice should be used on the adjacent paved road to the construction site. Paved
roads should be inspected on a daily basis and more frequently as needed.
• Saw Cutting Pollution Prevention prevents dust and slurry from asphalt and concrete
saw cutting activities from migrating into the existing storm drain system. Slurry and
cuttings shall be vacuumed during cutting and surface operations and shall not be allowed
to remain on pavement surface overnight. Collected slurry and cuttings shall be disposed of
in a manner that does not violate groundwater or surface water standards.
• Surface Roughening is provided following grading activities to slow the effects of
wind erosion. Roughening can be used as a temporary BMP and is a technique used
for creating unevenness on bare soil through the construction of furrows (groove
cuts) running across a slope or by utilization of construction equipment to track the
soil surface. The primary function of surface roughening is to reduce erosion
potential by decreasing runoff velocities, reducing the length of sheet flow trapping
sediment, and increasing infiltration of water into the soil.
• Temporary Seeding is the establishment of a temporary vegetative cover on a
graded area that will be exposed for longer 30 days. Temporary seeding can be used
on areas requiring temporary protection that will eventually need permanent
vegetation at the completion of the construction or it can be used for areas that will
Stormwater Management Plan
Registry Ridge Seventh Filing
Fort Collins, CO
11 U14012-SWMP.docx
be re-disturbed after a period of inactivity. The seed mix 100% smooth brome at a
minimum application rate of 30 pls/lbs/acre. Fertilizer and Mulch shall be included
as specified on the plans.
• Temporary Erosion Control Fabric is comprised of a temporary degradable erosion
control blanket designed to provide immediate erosion protection and vegetation
establishment assistance on moderate slopes and low to medium-flow channels
where bare-ground seeding and loose mulches often fail. Temporary erosion control
blankets are being recommended moderate slopes that do not require permanent
turf reinforcement matting.
• Vehicle Tracking Control is a stabilized stone pad located at points of ingress and
egress on a construction site and acts as a temporary BMP. The stone pad is
designed to reduce the amount of mud transported onto public roads by
construction traffic by removing mud and sediment from the vehicle’s wheels when
it drives over the gravel pad. These areas are limited to the minimum number
necessary to provide functional construction access and are installed prior to grading
activities. Whenever the construction entrance exists onto a public road, the road
shall be cleaned at the end of each day. Vehicle Tracking Control will also be used
on this site at any stockpile area exits.
• Wattle Sediment Protection is a temporary BMP that are typically used as check
structures in areas of concentrated water flow such as swales, grassed waterways,
and down drains. They can be installed in combination with any type of rolled
erosion control blanket or channel liner and function by slowing water velocity,
settling out sediment, and preventing undermining of the channel lining material.
Wattles for swale protection should be installed following rough grading of channel
areas. Sizing and spacing shall be per manufacturer’s recommendation.
• Wind Borne Sediment and Dust Control measures will be provided during the
construction process to control wind borne sediment. During grading activities,
water will be applied to the disturbed soils for the purpose of maintaining cohesion
with clay type soils and also to meet moisture requirements for compaction of
disturbed soils. Other measures of mitigation for wind erosion may include the
timely installation of seed and mulch following the establishment of final grade, and
the timely installation of pavement following completion of utility trenching
operations and curb construction. Open areas should be kept in a roughened
condition (see Surface Roughening above).
Stormwater Management Plan
Registry Ridge Seventh Filing
Fort Collins, CO
12 U14012-SWMP.docx
Permanent BMP’s
• Grass-Lined Swales (included as part of permanent seeding or other permanently
stabilized swales) are permanent landscaped channels constructed generally below
grade to convey runoff or channel water to a desired location. The grass-lined areas
allow for infiltration to occur as well as including a flow path across a vegetated
surface slowing the conveyance rate of storm water runoff.
• Permanent Seeding and Planting is the establishment of a permanent perennial
vegetation such as trees, shrubs, vines, grasses/sod, or legumes on exposed areas
for final permanent stabilization in order to provide stabilization of the soil by
holding soil particles in place. These items should be installed as per the approved
Landscape Plan. Soil Amendments shall be incorporated in all landscape areas to a
depth of 6” at a rate of 3 cubic yards per 1000 square feet of area unless 4” of loose
topsoil have been imported onto the site over 4” of loosened subgrade soils.
Permanent Landscaping reduces storm water runoff velocity, maintains sheet flow,
protects the soil surface from erosion, promotes infiltration of runoff, and improves
wildlife habitat.
• Bioretention is a permanent BMP that is engineered to utilize bioretention in a
depressed landscape area design to capture and filter or infiltrate the water quality
capture volume. BMPs that utilize bioretention are frequently referred to as rain
gardens or porous landscape detention areas.
• Preservation of Existing Vegetation should occur where no construction activity is
expected to occur. Preservation of natural vegetation is generally a permanent BMP
and is applicable to construction sites with pre-existing vegetation. Only land
needed for building activities and vehicle traffic needs is to be cleared.
• Storm Sewer Outlet Protection devices are structurally lined aprons or other energy
dissipating devices placed at the outlets of pipes or paved channel sections. Outlet
protection devices prevent scour at storm water outlets and minimize the potential
of downstream erosion by reducing the velocity of storm water flows. Riprap or turf
reinforcement matting will be used downstream of storm sewer outfalls as pipe
outlet protection. Outlet Protection is installed with the storm sewer construction
and serves as a permanent structural BMP.
B. Erosion Control Sequencing
This project will have three distinct erosion control phases. The initial phase will be
installing erosion control items prior to any construction on the site. After the initial
erosion control items have been installed, the next phase will consist of site demolition,
Stormwater Management Plan
Registry Ridge Seventh Filing
Fort Collins, CO
13 U14012-SWMP.docx
grading activities and construction of the infrastructure (utilities, storm sewer, roads,
and development of landscaped areas). The final stage will include the construction of
the site hard surfaces including roads, driveways, and sidewalks. Each of the phases is
described below, including necessary erosion control items.
A SWMP drawing is located in the Appendix that includes the minimum required BMP’s
found on the Sediment and Erosion Control Plans. It should be filled in with the
appropriate BMP’s as they are constructed/placed within the project site.
Phase 1 – Prior to Construction
• Preserve Existing Vegetation – Before construction commencement, areas that are
not disturbed by construction activity should be preserved as needed with
construction fencing, silt fencing, signage, or other means to keep vehicular traffic
out of the area to be left undisturbed.
• Silt Fence – Before construction commencement, silt fence will be placed
downstream of areas where runoff from construction activities is expected to occur.
• Staging Area – A concrete wash out area, fueling area, and other staging areas will
be provided during the construction process at least 100’ from any storm water
conveyance. A staging area is to be shown on the SWMP drawing when its location
is identified.
• Vehicle Tracking Control – Before commencement of construction, vehicle tracking
control shall be placed at the location shown west of Overland Trail along West
Elizabeth Street. Any other points of ingress and egress planned by the contractor
and approved by the owner shall also receive suitable vehicle tracking control
BMP's.
• Construction Fence – Before commencement of construction, construction fence
shall be placed at the contractor’s discretion (or as shown in the plans) to limit
access by construction equipment and personal vehicles to designated areas of
ingress and egress.
Phase 2 – Site Demolition, Site Grading, and Infrastructure Construction
The items installed in Phase 1 shall be in place, functional, and maintained during and
following the site demolition and site grading operations. In addition to those items, the
following BMP’s shall be installed.
Stormwater Management Plan
Registry Ridge Seventh Filing
Fort Collins, CO
14 U14012-SWMP.docx
• Wind Borne Sediment and Dust Control – Wind borne sediment and dust control
measures should be implemented during grading activities. This will be particularly
important to consider prior to the establishment of seeding.
• Inlet Protection – Wattles will be placed at curb inlets and area inlets located
throughout the site immediately after the inlet is constructed / installed. Existing
inlets shall be protected prior to heavy equipment staging, demolition, or
commencement of construction activities.
• Swale Protection – Straw wattles will be placed within the swales immediately
following rough grading. Wattles shall be placed across the swale for every 2’ of
drop in swale elevation or every 300'.
• Slope Protection – Surface roughening and contour furrows shall occur after rough
grading.
• Permanent Seeding – Permanent seeding or landscaping shall be placed
immediately in areas that are final graded and where little future disturbance is
expected.
• Temporary Seeding – The majority of the landscaped areas will be permanently
seeded or planted. However, if disturbed areas are left without permanent
stabilization 30 days after grading, temporary seeding will be required.
• Outlet Protection– Riprap and/or permanent turf reinforcement matting will be
placed immediately downstream of storm sewer outfalls.
• Concrete Washout Area – Concrete washout areas will be placed prior to, and
maintained during, the completion of concrete work.
• Rock Socks – Rock socks will be placed to replace other inlet protection devices as
required after paving operations have been completed.
Phase 3 –Roadway and Sidewalk Construction and Final Grading
This phase will likely begin before the seeding has been established throughout the site,
so it is expected that majority of the BMP’s shown in Phase 1 and Phase 2 will be in
place at the beginning of this phase. As roads are paved and seeding is established
there will be previously placed BMP's such as vehicle tracking control devices and some
sections of silt fence that may be removed. There are other items such as inlet
protection, silt fence, and swale protection that may only be removed after all
construction is complete and upstream areas are established.

15 U14012-SWMP.docx
C. Materials Handling and Spill Prevention
The site development includes appropriate construction staging and stockpile areas
identified on the SWMP Plans shown in Appendix A. Stormwater runoff generated from
the staging areas will be routed to a temporary sedimentation area where runoff will be
contained and filtered before being discharged downstream. The staging/stockpile
area(s) may be moved to a location no closer than 100’ from a storm water conveyance.
Vehicle tracking control should be placed at the stockpile area entrance/exit and silt
fence should surround it. If relocated, the SWMP should be updated with the actual
location of the stockpile/staging area(s).
Chemicals, fuels, lubricants, and paints stored on-site will be in water tight containers
and covered as necessary and stored in a bermed area, a storage building, or within a
vehicle to act as secondary containment. Storage of onsite materials including building
materials, fertilizers, waterline, sanitary sewer, and storm sewer will be covered and
placed on pallets to prevent direct contact with the ground and potential surface runoff.
Concrete and asphalt batch plants are not anticipated on this site and thus are not
included in this SWMP.
In the event of a spill or accident, it shall be contained and disposed of so that it will not
flow from the site or soak into the soil. Once construction is completed, concrete waste
and contaminated soil will be disposed of properly. The SWMP Administrator should be
notified of spills.
IV. Other Controls
The following includes other measures to control pollutants:
• Solid waste materials, including disposable materials incidental to the major
construction activities, will be collected in containers. The containers will be emptied
periodically and trucked away from the site. Dumpsters shall have covers.
• Water used to establish and maintain grass, for dust control, and for other purposes
during the construction phase must originate from a public water supply or private well
approved by the Colorado Department of Public Health and Environment unless
otherwise approved.
• Sanitary facilities shall be provided at the site throughout construction activities. They
shall be utilized by construction personnel and serviced regularly by a commercial
operator. They shall be located a minimum of 5 feet from the curb or 50 feet from
inlets and must be anchored. If sanitary facilities are located on a paved surface, a
secondary containment BMP will need to be constructed.
Stormwater Management Plan
Registry Ridge Seventh Filing
Fort Collins, CO
16 U14012-SWMP.docx
• Access off of paved roads should be limited.
V. Final Stabilization and Long-term Stormwater Quality
Final stabilization is reached when all soil disturbing activities at the site have been completed
and vegetative cover has been established with a density of at least 70 percent of pre-
disturbance levels or when equivalent permanent erosion reduction methods have been
utilized. Upon final stabilization, temporary BMP’s may be removed, unless they are required
to remain in place for future phasing.
Water quality enhancements are provided in areas where grass-lined swales are provided for
storm water conveyance. The soft bottom/overbank areas allow for infiltration to occur as well
as including a flow path across a vegetated surface slowing the conveyance rate of storm water
runoff.
VI. Inspection and Maintenance Procedures
Upon completion of each phase of construction, appropriate measures shall be taken to inspect
and maintain existing erosion control features, as described herein or per manufacturers
specifications (whichever is more stringent) and install new erosion control elements associated
with each phase of construction.
The temporary BMP’s will be inspected and documented at a minimum of once every 14 days
and after each precipitation or snowmelt event. The SWMP will be kept up-to-date with
inspection records, maintenance procedures, and changes. Records should include complete
inspection reports for each inspection, maintenance, and/or repair. A record-keeping system is
recommended in managing inspection and maintenance reports and should include all
maintenance records, spill response, weather conditions, training, correspondence, etc. A
blank copy the CDOT Stormwater Field Inspection Report is provided in Appendix C.
Preventative maintenance also involves the regular inspection and testing of equipment, timely
maintenance of the equipment, and complete records of the maintenance and inspections of
the equipment. The maintenance and inspection records should be kept on site and made
available upon request.
Inspections must include the observation of the construction site perimeter, runoff discharge
points, disturbed areas, staging areas (including concrete washout areas and fueling areas),
erosion and sediment control measures identified in this SWMP, and any other structural BMP’s
that may require maintenance. The inspection must determine if there is evidence of or
potential for pollutants to enter the drainage system and if they should be modified, replaced,
or added to.
The following list includes some recommended maintenance procedures:
Stormwater Management Plan
Registry Ridge Seventh Filing
Fort Collins, CO
17 U14012-SWMP.docx
• Erosion and sediment control measures determined, upon inspection, to be in need of
repair shall be maintained before the next anticipated storm event or as necessary to
maintain continued effectiveness of erosion and sediment control measures. If it is
impractical to maintain erosion and sediment control measures before the next storm
event, maintenance should be accomplished as soon as practical.
• Locations where vehicles enter or exit the site shall be inspected for evidence of sediment
being tracked off-site by construction traffic. Such sediment shall be removed before it can
be conveyed to the receiving storm drains or creeks.
• Seeded areas will be checked to see that grass coverage is maintained. Areas will be
watered, fertilized, and reseeded as needed.
• It is the responsibility of the Site Operator to maintain effective pollutant discharge
controls. Actual physical site conditions or contractor practices could make it necessary to
install more control than are shown on the Erosion Control Plan. For example, localized
concentrations of surface runoff or unusually steep areas could require additional erosion
control devices. Assessing the need for, and implementing additional controls will be a
continuing aspect of the SWMP until final stabilization. This plan intends to control water-
borne and liquid pollutant discharges by some combination of interception, filtration, and
containment. Parties implementing this plan must remain alert to the need to periodically
refine and update the plan in order to accomplish the intended goals.
• Sediment that has escaped the construction site must be removed at a frequency sufficient
to minimize off-site impacts.

(SEE FINAL PLAN SET FOR COMPLETE SET OF GENERAL NOTES)
1. All materials, workmanship, and construction of public improvements shall meet or exceed the standards and specifications set forth in the Larimer
County Urban Area Street Standards and applicable state and federal regulations. Where there is conflict between these plans and the specifications, or
any applicable standards, the most restrictive standard shall apply. All work shall be inspected and approved by the City of Fort Collins.
14. A State Construction Dewatering Wastewater Discharge Permit is required if dewatering is required in order to install utilities or water is discharged into a
storm sewer, channel, irrigation ditch or any waters of the United States.
15. The Developer shall comply with all terms and conditions of the Colorado Permit for Storm Water Discharge (Contact Colorado Department of Health,
Water Quality Control Division, (303) 692-3590), the Storm Water Management Plan, and the Erosion Control Plan.
20. Temporary erosion control during construction shall be provided as shown on the Erosion Control Plan. All erosion control measures shall be maintained
in good repair by the Developer, until such time as the entire disturbed areas is stabilized with hard surface or landscaping.
21. The Developer shall be responsible for insuring that no mud or debris shall be tracked onto the existing public street system. Mud and debris must be
removed within 24 hours by an appropriate mechanical method (i.e. machine broom sweep, light duty front-end loader, etc.) or as approved by the the
City of Fort Collins street inspector.
23. The Developer shall be responsible for obtaining all necessary permits for all applicable agencies prior to commencement of construction. The Developer
shall notify the the City of Fort Collins Inspector (Fort Collins - 221-6605) and the City of Fort Collins Erosion Control Inspector (Fort Collins - 221-6700)
at least 2 working days prior to the start of any earth disturbing activity, or construction on any and all public improvements. If the City of Fort Collins
Engineer is not available after proper notice of construction activity has been provided, the Developer may commence work in the Engineer absence.
However, the City of Fort Collins reserves the right not to accept the improvement if subsequent testing reveals an improper installation.
39. The Developer shall be responsible for recording as-built information on a set of record drawings kept on the construction site, and available to the
Larimer County's Inspector at all times. Upon completion of the work, the contractor(s) shall submit record drawings to the City of Fort Collins Engineer.
STANDARD EROSION AND SEDIMENT CONTROL CONSTRUCTION PLAN NOTES
1. The erosion control inspector must be notified at least twenty-four (24) hours prior to any construction on this site.
2. There shall be no earth-disturbing activity outside the limits designated on the accepted plans.
3. All required perimeter silt and construction fencing shall be installed prior to any land disturbing activity (stockpiling, stripping, grading, etc). All other
required erosion control measures shall be installed at the appropriate time in the construction sequence as indicated in the approved project schedule,
construction plans, and erosion control report.
4. At all times during construction, the developer shall be responsible for preventing and controlling on-site erosion including keeping the property
sufficiently watered so as to minimize windblown sediment. The developer shall also be responsible for installing and maintaining all erosion control
facilities shown herein.
5. Pre-disturbance vegetation shall be protected and retained wherever possible. Removal or disturbance of existing vegetation shall be limited to the
area(s) required for immediate construction operations, and for the shortest practical period of time.
6. All soils exposed during land disturbing activity (striping, grading, utility installations, stockpiling, filling, etc.) shall be kept in a roughened condition by
ripping or disking along land contours until mulch, vegetation, or other permanent erosion control BMPS are installed. No soils in areas outside project
street rights-of-way shall remain exposed by land disturbing activity for more than thirty (30) days before required temporary or permanent erosion control
(e.g. seed/mulch, landscaping, etc.) is installed, unless otherwise approved by the city/county.

7. In order to minimize erosion potential, all temporary (structural) erosion control measures shall:
A. Be inspected at a minimum of once every two (2) weeks and after each significant storm event and repaired or reconstructed as necessary in order
to ensure the continued performance of their intended function.
B. Remain in place until such time as all the surrounding disturbed areas are sufficiently stabilized as determined by the erosion control inspector.
C. Be removed after the site has been sufficiently stabilized as determined by the erosion control inspector.
8. When temporary erosion control measures are removed, the developer shall be responsible for the cleanup and removal of all sediment and debris from
all drainage infrastructure and other public facilities.
9. The contractor shall immediately clean up any construction materials inadvertently deposited on existing streets, sidewalks, or other public rights of way,
and make sure streets and walkways are cleaned at the end of each working day.
10. 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 waters of the United States.
11. No soil stockpile shall exceed ten (10) feet in height. All soil stockpiles shall be protected from sediment transport by surface roughening, watering, and
perimeter silt fencing. Any soil stockpile remaining after thirty (30) days shall be seeded and mulched.
12. The storm water volume capacity of detention ponds will be restored and storm sewer lines will be cleaned upon completion of the project and before
turning the maintenance over to the city/county or Homeowners Association (HOA).
13. City ordinance and Colorado Discharge Permit System (CDPS) requirements make it unlawful to discharge or allow the discharge of any pollutant or
contaminated water from construction sites. Pollutants include, but are not limited to discarded building materials, concrete truck washout, chemicals, oil
and gas products, litter, and sanitary waste. The developer shall at all times take whatever measures are necessary to assure the proper containment
and disposal of pollutants on the site in accordance with any and all applicable local, state, and federal regulations.
14. A designated area shall be provided on site for concrete truck chute washout. The area shall be constructed so as to contain washout material and
located at least fifty (50) feet away from any waterway during construction. Upon completion of construction activities the concrete washout material will
be removed and properly disposed of prior to the area being restored.
15. Conditions in the field may warrant erosion control measures in addition to what is shown on these plans. The developer shall implement whatever
measures are determined necessary, as directed by the city/county.
16. A vehicle tracking control pad shall be installed when needed for construction equipment, including but not limited to personal vehicles exiting existing
roadways. No earthen materials, i.e. stone, dirt, etc. shall be placed in the curb & gutter or roadway as a ramp to access temporary stockpiles, staging
areas, construction materials, concrete washout areas, and/or building sites.
