a. General. In order to provide for streets of suitable location, width, and improvement to accommodate prospective traffic and afford satisfactory access for police, fire-fighting, snow removal, sanitation and street maintenance equipment, and to coordinate street location in order to achieve a convenient system and avoid undue hardships to adjoining properties, the following design standards for streets are required.
b. Street Surfacing and Improvements. After sewer and water utilities have been installed by the developer, the applicant shall construct curbs and gutters and shall surface or cause the roadways to be surfaced to the widths prescribed in these regulations. Said surfacing shall be of such character as is suitable for the expected traffic and in harmony with similar improvements in the surrounding areas. Types of pavement shall be as determined by the Design Standards. Adequate provisions shall be made for culverts, drains and bridges. All street pavement, shoulders, drainage improvements and structures, curbs, turn-arounds, and sidewalks shall conform to all construction standards and specifications adopted by the Design Standards and shall be incorporated into the construction plans required to be submitted by the developer for plat approval.
c. Excess Right-of-Way. Right-of-way widths in excess of the standards designed in these regulations shall be required whenever, due to topography, additional width necessary to provide for adequate and stable earth slopes. Such slopes shall not be in excess of three to one.
d. Railroads and Limited Access Highways. Railroad right-of-way and limited access highways where so located as to affect the subdivisions of adjoining lands shall be treated as follows:
1. In residential districts a buffer strip at least twenty-five (25) feet in depth in addition to the normal depth of the lot required in the district shall be provided adjacent to any limited access highway. This strip shall be part of the platted lots and shall be designated on the plat: This strip is reserved for screening. The placement of structures hereon other than earth berms, walls, fences and other landscape screening devices approved by the Commission is prohibited.
2. In districts zoned for business, commercial or industrial uses, the nearest street extending parallel or approximately parallel to a railroad shall, wherever practical, be at a sufficient distance therefrom to ensure a suitable depth for commercial or industrial sites.
3. Streets parallel to a railroad when intersecting for a street which crosses the railroad at grade shall to the extent practicable, be at a distance of at least one hundred fifty (150) feet from the railroad right-of- way. Such distance shall be determined with due consideration of the minimum distance required for future separation of grades by means of appropriate approach gradients. (Ord. No. 94-9, § V, J, 8-9-94)
