The Developer is responsible for providing all labor and materials necessary forthe completion of the intended improvements shown on these drawings, ordesignated to be provided, installed, or constructed, unless specifically notedotherwise.18. Dimensions for layout and construction are not to be scaled from any drawing. Ifpertinent dimensions are not shown, contact the Designer for clarification, andannotate the dimension on the record drawings.19. The Developer shall have, onsite at all times, one (1) signed copy of theapproved plans, one (1) copy of the appropriate standards and specifications,and a copy of any permits and extension agreements needed for the job. If,during the construction process, conditions are encountered which could indicatea situation that is not identified in the plans or specifications, the Developer shallcontact the Designer and the Larimer County Engineering Departmentimmediately.20. The Designer shall provide, in this location on the plan, the location anddescription of the nearest survey benchmarks (1) for the project as well as thebasis of bearings. The information shall be as follows:Benchmarks—Local Entity survey.B.M.Number___________________, Elev.=_____________________,Description_______________________________________________.21. All stationing is based on centerline of roadways unless otherwise noted.22. Upon completion of construction, the site shall be cleaned and restored to acondition equal to, or better than, that which existed before construction, or to thegrades and condition as required by these plans. Any existing improvementsdestroyed, damaged or removed due to construction of this project, shall bereplaced or restored in like kind at the Developer’s expense, unless otherwiseindicated on these plans, prior to the acceptance of completed improvements.23. The Larimer County Engineering Department shall not be responsible for themaintenance of roadway and appurtenant improvements, including stormdrainage structures and pipes.24.

Temporary erosion control during construction shall be provided as shown on theErosion Control Plan and shall be maintained in good repair by the Developer.Temporary erosion control measures shall not be removed until such time as alltributary-disturbed areas are sufficiently stabilized as determined by the LarimerCounty Engineering Department. When temporary erosion control measures areremoved, the Developer shall be responsible for the clean-up and removal of allsediment and debris from all drainage and other public facilities.5. Silt and sediment, within Right-of-Way, shall be removed after each substantialrainfall. The Developer shall be responsible for insuring that no mud or debrisshall be tracked onto the existing public street system. Mud and debris must beremoved within 24 hours by an appropriate mechanical method (i.e. machinebroom sweep, light duty front-end loader, etc.) or as approved by Larimer CountyEngineering Department.6. All perimeter erosion control measures shall be installed and functional, prior toany other earth-disturbing activity. All other structural erosion control measuresshall be implemented as soon as the facilities, around which they are based,become operational.7. Any erosion control facility damaged or destroyed prematurely, by any means,shall be immediately repaired by the Developer.8. There shall be no earth-disturbing activity outside the limits designated on theseplans.9. Top soil shall be removed and stock piled prior to overlot grading operations.10. Conditions in the field may warrant erosion control measures in addition to whatis shown on these plans. The Developer shall implement whatever measures aredetermined necessary, as directed by the Larimer County EngineeringDepartment.11. Negative impacts to downstream areas caused by overlot grading are to bemonitored and corrected by the Developer. Any off-site clean-up, directed by TheLarimer County Engineering Department, (including street cleaning), shall becompleted within 24-hours of written instruction, or risk construction stoppage.12. All areas disturbed by this project shall be seeded and mulched in accordancewith these specifications after grading completion.a. All areas for seeding shall be tilled to break up rooting restrictive layers, havea minimum of 4 inches of topsoil reapplied, and then be harrowed, and rolledor packed, to prepare the required firm seed bed.b. The seed bed shall be well-settled and firm, but friable enough so that seedcan be placed at the seeding depths specified. The seed bed shall bereasonably free of weeds.c. All seeding areas shall be fertilized, unless field evidence or laboratory soilanalysis indicates sufficient amounts of nitrogen (N) and 40 pounds availablephosphate (P205) per acre. Time of application will be as applicable to thekind of fertilizer and type of equipment used.Larimer County Rural Area Road Standards Page H-5October 22, 2007
