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

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.

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

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

least two weeks prior to the release of a certificate of occupancy for single family units. For commercial properties, certification shall by
submitted to the Stormwater Utility Department at least two weeks prior to the release of any building permits in excess of those allowed
prior to certification per the Development Agreement.
E. Utility Notes
1.All waterline and sanitary sewer construction shall conform to the Fort Collins Utility standards and specifications current to date of
construction.
2.The minimum cover over water lines is 4.5 feet and the maximum cover is 5.5 feet unless otherwise noted in the plans and approved by the
water utility.
3.Water mains shall be poly-wrapped D.I.P, or PVC with tracer wire.
4.HDPE pipe may be used for 1-1/2 and 2 inch water services. The pipe shall meet the standards of AWWA 901, NSF Standard 61 and
ASTM. The HDPE pipe shall be SDR 9 having a pressure rating of 200 psi. Stiffeners shall be used at all fittings and connections. 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 box and tracer
wire test lid per City Water Detail 25.
F. Infill and Redevelopment Notes
1.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.
