<br />I. Analysis of the population density to be served; <br />II. Estimates of traffic volumes expected over a <br />20-year period; <br />III. Proposed classifications and design speeds; <br />IV. Preliminary alignments and road grades; <br />V. A brief review of fiscal impact in relation to <br />County road maintenance; and <br />VI. Analysis of impacts to existing roadways and <br />adjacent properties. <br />All detailed plans and specifications, including all <br />road development components of a Preliminary Plan <br />submission, shall be prepared and certified by a <br />Professional Engineer registered in the State of <br />Colorado, sufficiently detailed to facilitate review, <br />and -- when not related to a new subdivision -- <br />submitted for County Engineer and Road Superintendent <br />review at least 60 days prior to desired construction <br />date. If construction doesn't commence within one year <br />following the applicable approval, detailed design must <br />be re-submitted, and any amendments to Land Use code <br />standards made in the interim shall apply. <br />Alternately, a phasing schedule may be submitted for <br />approval. All detailed plans and specifications, <br />including all road development components of a <br />Preliminary Plan submission, shall include: <br />VII. Profiles for all roads, including existing and <br />proposed sewer and water lines, showing grades; <br />lengths of vertical curves; stationing and <br />elevations of beginning and end of vertical curves <br />and point of intersection of vertical curves; <br />existing grade or ground lines by dashed line; <br />culverts, structures, and other controls. All <br />profile views shall be drawn to a scale of 1" _ <br />50' horizontal, and 1" = 5' vertical on 24"x 36" <br />sheets; <br />VIII.A description of at least two usable benchmarks <br />within ~ mile; USGS or BLM benchmarks shall be <br />used when possible; <br />IX. Layout of road showing length of tangents and <br />curves, widths of rights-of-way, slope lines <br />demonstrating sufficient right-of-way width, <br />stationing of beginning and end of curves, curve <br />radii, delta angles, bearings, distances, <br />Page 5-5-3 <br />
