A. GENERAL NOTES
1.All materials, workmanship, and construction of public improvements shall meet or exceed the standards and specifications set forth in the Larimer
County Urban Area Street Standards and applicable state and federal regulations. Where there is conflict between these plans and the
specifications, or any applicable standards, the most restrictive standard shall apply. All work shall be inspected and approved by the City of Fort

2.All references to any published standards shall refer to the latest revision of said standard, unless specifically stated otherwise.
3.These public improvement construction plans shall be valid for a period of three years from the date of approval by the City of Fort Collins Engineer.
Use of these plans after the expiration date will require a new review and approval process by the City of Fort Collins prior to commencement of
any work shown in these plans.
4.The engineer who has prepared these plans, by execution and/or seal hereof, does hereby affirm responsibility to the City of Fort Collins, as
beneficiary of said engineer's work, for any errors and omissions contained in these plans, and approval of these plans by the City of Fort Collins
Engineer shall not relieve the engineer who has prepared these plans of all such responsibility. Further, to the extent permitted by law, the engineer

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

results of the original geotechnical report, the Developer shall be responsible for a re-design of the subject pavement 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

ELEV.=5025.74
Please Note: This plan set is using NAVD88 for a vertical datum. Surrounding developments have used NGVD29 Unadjusted for
their vertical datums.
If NGVD29 Unadjusted Datum is required for any purpose, the following equation should be used:
NGVD29 Unadjusted = NAVD88 - 3.18'
Basis of Bearings

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,

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.

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

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.

Water Detail 11A.
F.INFILL AND REDEVELOPMENT NOTE
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.
