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's absence. However, the City of Fort Collins reserves the right not to accept the
improvement if subsequent testing reveals an improper installation.
24. The Developer shall be responsible for obtaining soils tests within the Public Right-of-Way after right of way grading and all utility trench
work is complete and prior to the placement of curb, gutter, sidewalk and pavement. If the final soils/pavement design report does not

section or, the Developer may use the City of Fort Collins' default pavement thickness section(s). Regardless of the option used, all final
soils/pavement design reports shall be prepared by a licensed Professional Engineer. The final report shall be submitted to the Inspector a
minimum of 10 working days prior to placement of base and asphalt. Placement of curb, gutter, sidewalk, base and asphalt shall not occur

noted in the letter and then resolved with the City of Fort Collins before installation of base course or asphalt will be allowed on the streets.
26. All utility installations within or across the roadbed of new residential roads must be completed prior to the final stages of road construction.
For the purposes of these standards, any work except c/g above the subgrade is considered final stage work. All service lines must be
stubbed to the property lines and marked so as to reduce the excavation necessary for building connections.
27. Portions of Larimer County are within overlay districts. The Larimer County Flood Plain Resolution should be referred to for additional
criteria for roads within these districts.

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 wind blown 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 (stripping, 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 clean up 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 stormwater 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.

3. Where proposed paving adjoins existing asphalt, the existing asphalt shall be saw cut, a minimum distance of 12 inches from the existing
edge, to create a clean construction joint. The Developer shall be required to remove existing pavement to a distance where a clean
construction joint can be made. Wheel cuts shall not be allowed unless approved by the City of Fort Collins Engineer in Fort Collins.
4. Street subgrades shall be scarified the top 12 inches and re-compacted prior to subbase installation. No base material shall be laid until the

existing street condition shall be documented by the Inspector before any cuts are made. Cutting and patching shall be done in
conformance with Chapter 25, Reconstruction and Repair. The finished patch shall blend smoothly into the existing surface. The
determination of need for a complete overlay shall be made by the City of Fort Collins Engineer. All overlay work shall be coordinated with
adjacent landowners such that future projects do not cut the new asphalt overlay work.
