This article shall govern the construction of all roads, drainage structures, appurtenances and bridges, presented or designed to be presented for acceptance and maintenance by the Town of New Milford, and excavation, diversion of water runoff and other activities pertaining to town highways and streets. This article specifically exempts work done by the Town of New Milford.(b)Repealer. All ordinances or parts of ordinances conflicting with the provisions of this article, including the Road Ordinance of the Town of New Milford dated June 1, 1962, as amended, and the Ordinance Governing Certain Activities on Town Roads, Highways and Sidewalks, dated April 1, 1966, are hereby repealed.(c)Standards. The construction of roads, drainage structures, appurtenances and bridges shall be governed by standards contained in following.Editor's Note: is included at the end of this chapter.(d)Applicable state standards. Except where the terms of this article may alter them, the latest State of Connecticut Department of Transportation Standard Specifications for Roads, Bridges and Incidental Construction or revision thereof shall apply and govern and are hereby made part of this article.(e)Contours. As far as practicable, roads shall follow existing contours.(f)Turnarounds. All dead-end roads shall terminate in a turnaround 100 feet in diameter with a completely paved area 80 feet in diameter. The construction of all dead-end roads shall conform in every detail to the provisions of this article that apply to through streets. The road right-of-way should extend to the property line where possible.(g)Sidewalks. Sidewalks shall be constructed on one or both sides of all proposed streets where specified by the First Selectman and/or Planning Commission. If sidewalks are not required, grading back of the curbs may be required to provide for future sidewalks.(h)Drainage.(1)All roads and drives shall be properly drained and sufficient culverts, manholes and catch basins installed. No portion of any road shall be drained more than 350 feet in one direction without catch basins or other provisions for conducting water off of the road.(2)In case of extremely steep or flat grades or large drainage areas, the spacing of catch basins at a closer interval may be required unless a gutter flow analysis satisfactory to the Director of Public Works shows otherwise.(3)A drainage analysis map and drainage computations shall be submitted to the Planning Commission and to the Director of Public Works and shall be based on the following criteria:a.For drainage areas less than 100 acres, the rational formulas shall be used with a minimum coefficient of imperviousness of 60% for all developed areas or areas which may be developed. Higher values must be used for areas draining paved areas exclusively. Lower values may be used for open space. The following return frequency shall be used:[1]Ditches: 10 years.[2]Storm drains: 10 years.[3]Culverts and watercourses: 50 years.b.For drainage areas greater than 1,000 acres, the one-hundred-year flood flow used to establish the Department of Housing and Urban Development flood limit lines shall be used to determine waterway openings. These areas will require special consideration on a job basis and complete hydraulic data and preliminary structure design shall be submitted to the Director of Public Works for review.c.Asphalt-coated corrugated metal pipe shall be required under the following conditions:[1]Slopes 10% or greater.[2]Areas of unstable soil.[3]In areas with less than 36 inches of cover or excessive fill, the Director of Public Works shall specify the gauge of pipe.d.Type C catch basins will normally be required with curb set parallel to the roadway center line and top set parallel with the grade of the road. In areas outside of roadway paved area, a type C-L catch basin may be used. Flow capacity for these areas shall be computed to determine the elevation of the grate for depressed structures.e.Outlet ditches shall be designed so that the velocity of flow will not scour or erode the material. Where excessive velocity is expected riprap or other energy dissipators may be required.(i)Plan-profile drawings.(1)Plan-profile drawings of all proposed roads shall be submitted on plan profile sheets 24 by 36 inches. Plan-profiles shall be at a scale of one inch equals 40 feet in plan, and one inch equals 40 feet horizontal and one inch equals four feet vertical in profile. Elevations shall refer to approximate United States Coast and Geodetic Survey datum. Drawings shall include the following:a.Layout of proposed streets in both plan and profile indicating right-of-way dimensions as shown on the final subdivision plan, width of right-of-way and paving. Existing field elevations and proposed center line grade lines with stations every 50 feet, vertical curve data and percent of grade. North arrow and monumented control points shall be shown with at least two permanent bench marks with elevations indicated.b.Typical cross section of the streets with paving, shoulders, curbs and sidewalks in detail.c.Plan-profile drawings shall also show all utility lines, encroachment lines and all easements for utilities, drainage and other rights-of-way, with location, size and inverts of existing and new culverts, and the entire drainage system.d.If considered advisable by the Director of Public Works or the Planning Commission due to the terrain as determined from contours and the proposed profile showing original and final grades, cross sections of the proposed road shall be furnished indicating the relation of the proposed construction to the adjacent land by the holder of the road permit at intervals of every 50 feet, showing the original ground, top and toe of slopes, culverts or bridges. These sections shall extend at least 40 feet left and right of the center line.e.Where required in the judgment of the Director of Public Works, street intersections shall be developed at a larger scale, showing catch basins, gutter, road center line, curb and sidewalk elevations.(2)All of the above documents shall bear the appropriate seal as recommended by the Board of Registration for Professional Engineers and Land Surveyors of the State of Connecticut.(3)The above information shall be submitted for approval to the New Milford Planning Commission in accord with the New Milford Subdivision Regulations and Zoning Regulations. It shall then be referred to the Director of Public Works by the Planning Commission.Editor's Note: See and Appendix B of this volume.(4)Upon final approval of the above-listed submissions for any proposed roadway and auxiliary structures, seven copies of said documents will be required for filing by the town.Editor's Note: See also at the end of this article.(j)Tributary drainage to a state system. Where drainage is tributary to a portion of a Connecticut Department of Transportation drainage system, the holder of the road permit shall obtain the approval of the Connecticut Department of Transportation for such drainage and shall submit the approval to the Planning Commission with the other required documents.(k)Easements. Permanent easements, of a nature acceptable to the Town Counsel, shall be deeded to the town in all cases where drainage pipes or ditches cross or abut lands other than a street right-of-way. A minimum width of 20 feet shall be required and said easements shall be clearly defined on the final subdivision plan placed on file in the land records.(l)Right to drain required. Where drainage waters are discharged directly or indirectly onto adjacent landowners, the holder of the road permit shall secure and deed to the town a right to drain, acceptable to the Town Counsel, of said landowner.(m)House and foundation drains. House and foundation drains in no case shall be permitted to discharge onto the highway. Such drains shall be connected to catch basins or manholes. All such drainage connections shall be extended beyond the limits of the right-of-way prior to construction of the bituminous concrete.(n)Trees and shrubs. Trees or shrubs may be planted within a right-of-way line, provided that the lowest branches are at least eight feet above the road surface.(o)Not a public road. During construction and prior to the acceptance of any roadway by the town, the subdivider shall erect and maintain at each entrance point one sign which shall read "THIS IS NOT A PUBLIC ROAD." Such signs shall be removed by the subdivider within the immediate ten-day period following final acceptance by the town.(p)Open excavations. All open excavations shall be properly protected with suitable warning lights, signs, covering, planking, barricades and such other devices as may be prescribed by the Selectmen. All open excavation shall be immediately backfilled upon completion of work. Every attempt shall be made to minimize the length of trench open at any one time.(q)Traffic control. The Selectmen or their agent may require the holder of any permit under this article to provide police traffic control whenever, in their judgment, the normal flow of traffic or the public safety is impaired by any work or activity upon any town road or highway.
