[HISTORY: Adopted by the Town Board of the Town of Kinderhook 4-8-1991 by L.L. No. 1-1991 (Ch. A85 of the 1978 Code). Amendments noted where applicable.]
The purpose of this chapter is to regulate the design and construction of streets, thoroughfares or highways and all utilities therein in the Town of Kinderhook, Columbia County, New York. This chapter is to be used in conjunction with and is complementary to Chapter 215, Subdivision of Land, and Chapter 250, Zoning, of the Code of the Town of Kinderhook.
Wherever used in this chapter, the words "street" and/or "right-of-way" shall also mean a thoroughfare, highway or road.
Wherever used in this chapter, words in the singular number include the plural and words in the plural number include the singular.
The word "shall" is mandatory and not directory. Words used in the present tense include the future.
All applications for the dedication of streets and rights-of-way to the Town of Kinderhook shall be accompanied by a warranty or, if a warranty deed is not possible, by a quitclaim deed conveying said street and rights-of-way to the Town with all releases from mortgages or other claimants, together with a proper title search, covering at least 30 years to the time application is made, and also a tax search. Such application shall also be accompanied by a plan or plans which shall:
Be at a scale of one inch equals 50 feet. The use of any other scale must have had prior approval of the Town Planning Board.
Show contours based on United States Geological Survey datum and at an interval not greater than two feet. Interpolation of contours from other mapping shall not be accepted. This requirement may be waived by the Town Engineer.
Show a minimum of two benchmarks based on United States Geological Survey datum.
Show a location plan, at a minimum scale of one inch equals 2,000 feet, giving the location of the plot with relation to established streets.
Show, on a separate plan of the same scale as the subdivision plan, all drainage areas tributary to the development, show drainage area limits tributary to each catch basin or inlet with a tabulation of runoff to each structure and the total to each outfall and show detention area details with storage volume calculations, including maximum detention times to drain completely, and all based on the stormwater management plan as defined in Chapter 215, Subdivision of Land. Calculation of runoff shall be based on a method in general use for the area involved and approved by the Town Engineer. The method used shall be approved by the Town Engineer and shall be recognized as producing a problem-free storm drainage system. Calculations for all stormwater structures shall be based on rainfall intensities resulting from a storm of a ten-year return. The designer shall examine and report on the routing and effects on the area and system for the one-hundred-year storm event. The storm drainage plans, calculations and narratives shall be submitted to the Town Engineer for review.
Show all proposed streets, roads or highways and lots with necessary survey data.
Show proposed finished street with road or highway grade. A separate supplementary map of that portion of streets, roads or highways to be conveyed shall be submitted showing building lots and restrictions and names of abutting owners. (See also Article II, § 215-5, of Chapter 215, Subdivision of Land.)
Show the locations of soil borings along the streets or roads. Minimum boring depth shall be 10 feet, and the boring logs shall indicate depth to the water table, soil types, date of boring and other information normally shown on such logs. Borings shall be located on proposed street center lines and at three-hundred-foot spacings unless greater spacing is approved by the Town Engineer and Highway Superintendent. The Highway Superintendent or Town Engineer may require a more extensive soil investigation with an evaluation and recommendation by a soils engineer, at the expense of the subdivision owner/developer, as to the suitability of the subgrade to perform satisfactorily. (See also § A251-8 of this chapter.)
Show a complete profile of the streets at a horizontal scale of one inch equals 50 feet and a vertical scale of one inch equals five feet, together with the street plan (use a standard highway plan-profile format sheet to conform to this chapter, Chapter 215, Subdivision of Land, and Chapter 250, Zoning), and which profile shall show the original ground surface, finished grade proposed, all utilities, including water mains, sanitary sewers and storm sewers, together with all structures proposed.
Show size, type of pipe, class, valves, alignment and hydrant locations for potable water distribution system, after consultation with the Town Engineer as to the needed capacity and ability of the existing Town distribution system to supply the requirements, all in accordance with the New York State Health Department and Columbia County Health Department regulations and acceptable design and construction practice.
No street which is to be designed as part of a subdivision after the effective date of this chapter shall be accepted as a Town street except as it shall conform to the regulations herein provided and as it is in conformance with Chapter 215, Subdivision of Land, and Chapter 250, Zoning, of the Code of the Town of Kinderhook.
Water distribution system shall be designed and constructed in accordance with New York State and Columbia County Health Department regulations and Town regulations in effect at the time of construction of the systems.
Public utilities shall be installed without expense to the Town and under the supervision of the Town Superintendent of Highways and the Town Engineer. The installation of said utilities shall be accomplished without cutting of pavement within the Town Highway rights-of-way, and a permit shall be obtained from the Highway Superintendent for the work to be done. Power, telephone, cable TV and gas, where installed under the pavement, shall be placed in a protective sleeve. Unless a specific permit is issued by the Highway Superintendent, no pavement shall be broken and all facilities shall be jacked, bored or driven under said pavement only under his direction.
The arrangement of streets or highways hereinafter laid out shall, wherever possible, provide for the continuation of the principal streets existing in the adjoining subdivisions, or of their proper projection when the adjoining property is not subdivided, and shall be of a width as great as that of such existing streets but in no case have a right-of-way width less than 60 feet.
The minimum width of street or highway rights-of-way hereinafter laid out shall be 60 feet. These widths shall be measured from right-of-way line to right-of-way line. Said width shall be measured normal to the lines on tangents and on the radial lines on curves.
There shall be no reverse strips controlling access to streets, except where control of such strips is definitely placed in the Town under offer to dedicate.
Property lines at all street intersections shall be rounded sufficiently to allow a minimum radius on the property line of 25 feet.
All pipe and necessary appurtenances for the proper and satisfactory collection and disposal of subsurface or underground water from the rights-of-way of the proposed highways shown on the approved subdivision plan, in order to establish a satisfactory roadbed for such highways, shall be supplied and installed by the owner of the subdivision in accordance with the pertinent specifications of the Town. The necessity for draining subsurface water from the right-of-way of a proposed highway, the locations where such drainage is required and the extent of piping necessary to effect such drainage shall be determinations of the Superintendent of Highways and Town Engineer. These determinations by the Superintendent of Highways and Town Engineer may precede the construction of the proposed highway or may occur during construction as underground water conditions become evident. The Town Superintendent of Highways will notify the owner of such determinations as soon as possible after such determinations are made. Type of pipe, diameter and gauge of pipe, pipeline gradients, method of pipe placement and all materials required for the installation of such drainage shall conform to the requirements and specifications of the Town.
Streets designed to have one end permanently closed shall be provided at the closed end with a turnaround roadway having a minimum radius for the outside property line of at least 80 feet. Full pavement area shall extend to within 15 feet of the outside right-of-way line.
Street grades shall not exceed 8% nor be less than 1%. Particular attention shall be given to street design at intersections. Approach grades shall not exceed 3% within 120 feet of the street right-of-way line intersected and shall not exceed 1 1/2% within 40 feet of the right-of-way line intersected. Combinations of grades over 6% with curves of minimum radius shall not be used. Where the algebraic difference in street grades exceeds 2%, the grades shall be connected by a vertical curve to produce a safe transition.
Street intersections shall be at 90° within 100 feet of the intersected right-of-way line. Street tangents with a deflection angle greater than 1° shall be connected by a minimum radius of curve of 200 feet, measured to the center line of the right-of-way. Street layouts for proposed higher density development than standard R-C, AR, R-2, B-1, I-1 (that is for clustered or townhouse development) or MP Districts may be approved at less radius of curve, but traffic safety provisions and necessary street signage must be as recommended by a qualified traffic safety engineer employed and paid by the owner/developer at no cost to the Town.
Intersecting streets shall be so planned that blocks between street lines shall be not more than 1,200 feet in length, and any variance from this length because of an unusual topographic condition or more efficient land use shall have prior approval of the Planning Board.
The planting of street trees within the right-of-way is prohibited; however, shrubs with a mature height not greater than 18 inches, combined with grassed areas shall be planted and maintained until street dedication by the landowner/developer. These areas shall include the center mall areas of divided streets and turnarounds. The plan for this planting shall have prior approval of the Highway Superintendent. A minimum of two trees for each lot behind the right-of-way shall be as required by the Planning Board.
Sufficient monuments shall be placed to properly reproduce each and every street laid out. Street monuments shall be placed in the immediate vicinity of all intersections and at intervals not exceeding 500 feet on tangent lengths of over 1,000 feet. Where monuments are placed between intersections, they shall be placed in pairs, one on each side of the street, and shall be accurately correlated to one another by bearing (angle) and distance.
Monuments shall be of 4,000 pounds per square inch concrete reinforced with four No. 3 deformed reinforcing and shall be four inches square and four feet in length. A galvanized or stainless steel pin 3/8 inches in diameter shall be anchored on center and flush with the top of the monument. The top of the monument shall be set flush with the finished grade.
In general, storm sewers will be required and shall be designed to carry the flow tributary. The distance which water shall be allowed to run in open ditches will be determined in each individual case depending upon the various factors involved. In areas of minimum grade, this distance shall not exceed 750 feet and in areas of maximum grade, this distance shall not exceed 250 feet.
Storm sewers, where installed, shall be of reinforced concrete pipe or corrugated metal pipe (galvanized steel), fully coated, with paved invert and, generally, shall be laid on grades to produce a velocity of not less than three feet per second nor more than eight feet per second when flowing full. When the pipe is not exposed to sunlight, PVC or ABS N-12 pipe will be considered. Under special conditions involving circumstances such as level terrain and shallow surface water outlet, permission to install storm sewers at grades producing velocities of not less than two feet per second when flowing full may be granted by the Town Superintendent of Highways. Storm sewer design shall be on the basis of local ten-year storm frequency studies, except that structures for major streams or areas subject to property damage due to flooding shall be designed for a fifty-year-storm frequency and shall be such that a minimum of four feet 10 inches is maintained from invert of pipe to finish ground surface directly above.
Reinforcing concrete pipe shall conform to ASTM Specifications Class III for reinforced concrete pipe. In certain locations, the Highway Superintendent may require the use of ASTM Designation C-76 Class IV or Class V.
Corrugated galvanized steel pipe, multiplate pipe and pipe arches shall be fully coated with a paved invert and shall not be less than the gauge recommended by the American Association of State Highway Officials, but not less than sixteen-gauge. Lengths of CMP shall be joined with corrugated collars. All pipe ends shall be corrugated. All joints are to be encased in graded filter gravel, 15 inches either side of the joint to a minimum depth of 12 inches above and six inches below the pipe. Local soil conditions may increase these requirements. All CMP 48 inches in diameter and larger shall be strutted. Struts shall be removed after total compaction of the backfill material in six-inch lifts has been completed.
The use of helically formed corrugated steel pipe shall require reformed annular ends to receive standard connectors. The use of dimpled connectors is prohibited.
All storm sewers shall be constructed accurately to line and grade, properly bedded, and shall be so constructed that all joints are watertight unless open joints or weeps are approved by the Town Superintendent of Highways to permit groundwater infiltration.
Typical installation details are shown on the attached drawing. The design of stormwater inlet basins and manholes shall be acceptable to the Town Superintendent of Highways and shall be in accordance with current standard modern practice. In no case will the use of concrete manhole block less than eight inches in width be permitted.
Editor's Note: The drawing, as amended 11-8-2004 by L.L. No. 14-2004, is on file in the Town offices.
The design of poured, precast or prefabricated manhole structures shall be Fort Miller standard or equal and must have the approval of the Town Superintendent of Highways and/or the Town Engineer prior to installation. Pipe connections shall be completely sealed with hydraulic mortar for the full thickness of the structure wall.
The minimum inside diameter of pipe for storm sewer use shall be 12 inches. The minimum steel thickness for corrugated steel pipe shall be sixteen-gauge. Shallower or deeper installations than standard or in particularly corrosive soil or flow conditions shall require the use of a heavier gauge, subject to the approval of the Highway Superintendent.
All catch basin and junction structures over four feet in depth shall have substantial, noncorroding steps for safe access, and structures over eight feet in depth shall have an offset cone section. All structures less than eight feet in depth shall be equipped with a reinforced concrete flat top designed for a minimum H-20 highway load and set so the manhole opening is over the outlet pipe. Frames, grates and solid covers shall be Campbell Foundry Heavy Duty for Highway Traffic, or approved equal.
Underdrainage shall be installed when so directed by the Highway Superintendent and/or the Town Engineer.
The developer or owner laying out the streets or highways for acceptance by the Town shall obtain all necessary easements and/or rights-of-way to take care of all surface and ground water caused by reason of the development of said street or highway and by reason of the installation of culverts or surface drains or underdrains. No street or highway will be accepted by the Town of Kinderhook nor approved by the Town Superintendent of Highways before such necessary easements or rights-of-way have been obtained and passed upon by the attorney for the Town of Kinderhook. The width of easement or right-of-way shall be 30 feet minimum for installation depth of six feet or less. At the discretion of the Town Superintendent of Highways and/or the Town Engineer, greater installation depths may require wider easements or rights-of-way, depending upon particular circumstances.
Prior to being offered for dedication to the Town, all streets shall be completely graded, within the limits of the right-of-way, and all underground utilities shall have been installed in accordance with all provisions of this chapter, the base course of gravel shall have been placed, graded and compacted and paving and sidewalks, as required, shall have been installed in conformance with the applicable standards as shown on the attached drawings, Highway Cross-Sections-Town of Kinderhook.
