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 of Loveland.
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 asnecessary 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

material(s), concrete washout area(s) and/or building site(s).
CITY OF FORT COLLINS GRADING AND EROSION AND SEDIMENT
CONTROL NOTES
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 standard erosion control notes Fort Collins Stormwater Criteria Manual appendix f
page 2 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 Fort Collins Stormwater Criteria Manual Appendix f
page 3 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.
Fort Collins Stormwater Criteria Manual Appendix f page 4
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 limitsshall 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 Fort Collins Stormwater Criteria Manual Appendix F
page 5 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 sedimentfrom leaving the lot. see the individual lot details for further
clarification.
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. Fort Collins Stormwater Criteria Manual Appendix F page 6
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 Fort Collins Stormwater Criteria Manual
Appendix F page 7 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.
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 Fort Collins Stormwater Criteria Manual Appendix F page 8
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

approved equal to ensure seed will be able to germinate on the steep slopes. during a
season when seeding does Fort Collins Stormwater Criteria Manual Appendix F
page 9 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.
