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.
16. For additional information see separate Stormwater Management Plan / Erosion Control Report for 609 South College Avenue.
B. Street Improvement Notes

are not allowed.
6. When an existing asphalt street must be cut, the street must be restored to a condition equal to or better than its original condition. 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.
7. All traffic control devices shall be in conformance with these plans or as otherwise specified in M.U.T.C.D. (including Colorado supplement) and as
per the Right-of-Way Work Permit traffic control plan.
8. The Developer is required to perform a gutter water flow test in the presence of the City of Fort Collins Inspector and prior to installation of asphalt.
Gutters that hold more than 1/4 inch deep or 5 feet longitudinally, of water, shall be completely removed and reconstructed to drain properly.
9. Prior to placement of H.B.P. or concrete within the street and after moisture/density tests have been taken on the subgrade material (when a full
depth section is proposed) or on the subgrade and base material (when a composite section is proposed), a mechanical "proof roll" will be required.
The entire subgrade and/or base material shall be rolled with a heavily loaded vehicle having a total GVW of not less than 50,000 lbs. and a single
axle weight of at least 18,000 lbs. with pneumatic tires inflated to not less that 90 p.s.i.g. "Proof roll" vehicles shall not travel at speeds greater than
3 m.p.h. Any portion of the subgrade or base material which exhibits excessive pumping or deformation, as determined by the City of Fort Collins
Engineer, shall be reworked, replaced or otherwise modified to form a smooth, non-yielding surface. The City of Fort Collins Engineer shall be
notified at least 24 hours prior to the "proof roll." All "proof rolls" shall be preformed in the presence of an Inspector.
C. Traffic Signing and Pavement Marking Construction Notes
1. All signage and marking is subject to the General Notes on the cover sheet of these plans, as well as the Traffic Signing and Marking Construction

12. The Developer installing signs shall be responsible for locating and protecting all underground utilities.
13. Special care shall be taken in sign location to ensure an unobstructed view of each sign.
14. Signage and striping has been determined by information available at the time of review. Prior to initiation of the warranty period,the City of Fort
Collins Traffic Engineer reserves the right to require additional signage and/or striping if the City of Fort Collins Traffic Engineer determines that an
unforeseen condition warrants such signage according to the MUTCD or the CDOT M and S Standards. All signage and striping shall fall under the
requirements of the 2-year warranty period for new construction (except fair wear on traffic markings).
15. Sleeves for sign posts shall be required for use in islands/medians. Refer to Chapter 14, Traffic Control Devices, for additional detail.

installed with the HDPE service, and shall extend up the curb stop. The curb stop shall be covered with a metal valve box and "water" lid per City
Water Detail 11A.
INFILL AND REDEVELOPMENT NOTE
A. Despite everyone's best efforts, it is impossible to fully display subsurface information prior to excavation. This is especially true in areas of infill and
redevelopment. Unknown subsurface conditions can have cost and schedule implications. Prior to finalizing contract terms, it is strongly
recommended that the Owner and General Contractor have a candid discussion to formulate a strategy for dealing with such circumstances when
they arise. The process and procures should be in place prior to excavation. Allowances and contingencies can address the cost implications, but
additional measures are required to deal with scheduling and factors impacting sequence of work. The Architect, Engineer(s), and Construction
Surveyor should be made aware of the protocol for dealing with such unknown subsurface conditions prior to starting work.
