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.

Valve boxes and manholes are to be brought up to grade at the time of pavement placement or overlay. Valve box adjusting rings 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.

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. D. Storm Drainage Notes 1.The City of Fort Collins shall not be responsible for the maintenance of storm drainage facilities located on private property. Maintenance of onsite drainage facilities shall be the responsibility of the property owner(s). 2.All recommendations of the Final Drainage Report, dated March 1, 2023 by Northern Engineering shall be followed and implemented. 3.Prior to final inspection and acceptance by the City of Fort Collins, certification of the drainage facilities, by a registered engineer, must by submitted to and approved by the Stormwater Utility Department. Certification shall be submitted to the Stormwater Utility Department at least two weeks prior to the release of a certificate of occupancy for single family units.

Tracer wire shall be 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.
