EROSION 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 Erosion Control
Materials compiled for this project, and the following notes as all these materials are
applicable to this project.
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 the
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 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 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.
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 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
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.
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.
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) 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) 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.
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.
