16.16.010.7: STREETS AND STORM DRAINS:
   A.   General Provisions: Design standards and specifications for streets and storm drains are adopted by the board of county commissioners and amended as necessary. The Churchill County road department and planning department, hereinafter referred to as "county", will review all developments located within the Churchill County boundaries to evaluate the feasibility of integrating the development, presently or in the future, with Churchill County systems. Developers and their consulting engineers must meet with the county prior to any formal plan submittal to discuss proposed street design, alignment and layout to ensure compliance with the master plan and transportation plan, compliance with development standards and the feasibility of integration into existing and future systems. Once a project has been determined feasible, complete design and improvement plans are required for county review.
      1.   Legal Compliance: The developer and the engineer shall comply with all applicable federal and state laws, county ordinances, the Americans with disabilities act and regulations that affect the design of water, alternative water, wastewater systems, storm drainage and street improvements.
      2.   Agency Approvals: It is the responsibility of the developer and/or engineer of record to obtain the approvals of any required public agency prior to submitting improvement plans to Churchill County for approval, as the county will require copies of all permits, approvals, correspondence and/or requirements from other agencies directly associated with the development.
Churchill County requires written notice of approval by the appropriate review agency. The planning department of Churchill County may require a special use permit (SUP) for aboveground structures such as tanks and pump station buildings. The engineer of record must verify such requirements.
      3.   Approved Plans: Complete designs for storm drainage and street improvements, including any necessary dedications, easements, and rights of way, shall be submitted to and approved by Churchill County prior to the start of the project or final subdivision map being approved.
      4.   Facilities And Public Land: All Churchill County facilities shall be either on or within land owned by Churchill County, or within public easements.
      5.   Improvement Plans:
         a.   Plans By Engineer: All plans, specifications, calculations, reports, easements, and rights of way submitted to Churchill County shall be prepared, stamped, and signed by the engineer of record in accordance with Nevada Revised Statutes title 54, chapter 625. All submittals must be wet stamped by a civil engineer registered in the state of Nevada. Any improvement plans submitted to Churchill County that are not stamped by a civil engineer registered in the state of Nevada will be cause for rejection and resubmittal.
         b.   Improvement Plan Submittal: The initial submittal of improvement plans to Churchill County shall consist of the following:
            (1)   Three (3) sets of blue line or black line (OCE) plans, complete and in accordance with these review guidelines, along with any required specifications, computations, test data, reports, studies, analysis and other material requested by the county, including two (2) copies of a geotechnical report, three (3) copies of a drainage report, and a phasing plan and paving schedule, if applicable. Site plans and utility plans shall be prepared in a format compatible with Churchill County GIS data for integration with the GIS system. Churchill County uses the North American datum, 1983 (NAD 83) Nevada state plane, west zone (2703), U.S. survey foot projection. Vertical datum shall be North American vertical datum, 1988 (NAVD 88).
            (2)   The name, address and telephone number of the owner and the engineer of record to be contacted concerning the plans.
Churchill County will review the plans within thirty (30) calendar days of receipt. If alterations or revisions are required to the plans as submitted, the county will return one redlined improvement plan set with the corrections marked or indicated. If the improvement plans submitted are not prepared in accordance with these review guidelines or in keeping with the standards of the profession, Churchill County may return them unmarked and unapproved. Churchill County will not, under any circumstances, provide design by review. It is the engineer of record's responsibility to ensure proper engineering principles are incorporated in each design.
            (3)   The county engineer, or designee, is required to sign the cover sheet of all submittals.
         c.   Improvement Plan Resubmittal: Plans being resubmitted shall consist of a minimum of three (3) complete sets of plans and the returned redlined markup. Additional sets may be required by Churchill County. Plans being resubmitted that contain revisions or alterations other than those required by the county shall be identified as to the revisions made, and will be treated as an initial submittal.
      6.   Approved Plans: Once the improvement plans have been approved by the county, a signed set of approved plans will then be returned by the county to the engineer of record. All other pertinent review/approval agencies must provide authorization (signatures) prior to submitting to Churchill County for approval. Once all signatures are obtained (including, but not limited to, the Churchill County road department and Churchill County planning department), two (2) sets of approved plans will be retained by the county. Improvement plans shall be approved by Churchill County before construction begins. All construction shall be in accordance with the approved plans. Any required revisions to the approved plans shall be submitted by the engineer of record and approved by Churchill County prior to construction.
      7.   Project Inspection: Inspection of infrastructure within Churchill County rights of way will be performed by Churchill County or its authorized agent and all costs incurred will be paid by the owner/developer. Prior to construction, one percent (1%) of the engineer's estimate for the total project will be deposited with the road department for inspections. All other required materials testing and special inspections shall be performed in accordance with "Orange Book" guidelines by an independent inspection/quality control entity, which the owner/developer is responsible for securing and all costs incurred will be paid by the owner/developer. The owner/developer shall provide Churchill County with the materials testing firm and/or special inspector contact information in writing. Churchill County reserves the right to inspect the project at any time and to require replacement of the materials testing firm and special inspector used. The county or its authorized agent shall have the authority to approve field changes and shut down projects should this action be necessary in the best interest of the county. Reports of all materials testing and special inspections provided by the owner/developer shall be submitted to Churchill County prior to each phase of construction and a complete summary report shall be provided at the end of construction.
      8.   Bonding Requirements: All development projects are required to be bonded prior to project commencement unless the final map is to be filed after completion and acceptance of the improvements. The bond shall be based on a county approved engineer's estimate that includes a ten percent (10%) contingency of the project cost. The owner/developer shall be required to post a surety bond, cash or improvement security with Churchill County to guarantee the satisfactory completion of any improvements to county systems. The total bond amount shall be for one hundred ten percent (110%) of the total estimated cost that includes contingency. The owner/developer shall enter into a performance agreement with the county when the bond is posted, said agreement to be approved by the county prior to construction.
      9.   Preconstruction Meeting: A preconstruction meeting will be conducted by the developer prior to project commencement. A representative of Churchill County, the contractor, testing firm and engineer of record/independent inspector is required to be present at the preconstruction meeting. The developer must schedule the preconstruction meeting and shall provide at least one week prior notice to the county of the date and time of the meeting. Upon completion of the preconstruction meeting, a notice to proceed will be issued by Churchill County.
