(A) Generally. The regulations contained in this section are intended to encourage subdivision techniques which will minimize disturbance of the natural topographic features and other physical assets of the village hillside areas. A HILLSIDE AREA as referred to herein is defined as one with an average slope of 15% or more.
(B) Combining regulations. In large subdivisions, where only a portion of the tract qualifies as a hillside area, the regulations included in this section may be used in combination with the regulations contained in other chapters of the subdivision regulations.
(C) Determination of average slope. The applicant shall submit a detailed slope analysis to the Planning Commission staff prior to the submittal of preliminary subdivision drawings.
(D) Lotting. Lots proposed for hillside development must bear a relationship to existing topography and must be of a sufficient size and configuration to assure an appropriate placement of structures thereon. In all instances, the smallest lot shall satisfy the minimum lot size requirements specified in the zoning district governing the tract of land.
(E) Structure placement. The preliminary plans shall indicate the approximate location of each proposed structure. Structures should be placed in such a manner as to require a minimum amount of alteration to the existing contours and other physical assets of the site.
(F) Conformity to existing streets and Thoroughfare Plan. Whenever a hillside development abuts or contains an existing or proposed major thoroughfare, the standards as contained in these regulations shall be applicable. If a hillside development abuts or contains an existing local or collector residential street, it must meet the requirements of these regulations.
(G) Street design criteria.
(1) All streets will be designed as local streets. Their alignment will reflect existing topographic features and will be planned to prohibit through traffic.
(2) The Planning Commission may allow a reduction of pavement width to 18 feet.
(3) The Planning Commission may allow a maximum 12% street gradient on hillside streets.
(4) The Planning Commission shall require curbs, gutters, storm sewers and sidewalks for any hillside street which would normally require such improvements under §§ 152.085 through 152.096 of these regulations. However, along any hillside street curbs, gutters and storm sewers shall be required by the Planning Commission upon the Engineer’s recommendation and determination that such improvements are necessary to accommodate the surface drainage in order to prevent soil erosion or to protect the hillside or public improvements from potential damage.
(H) Resubdivision. A hillside development may be resubdivided only where no new building sites are created or where the resubdivider constructs all improvements or additional improvements to the design requirements set out in §§ 152.085 through 152.096. The record plat of a hillside development must clearly indicate that it is a special development approved under this chapter and shall include in its covenants and restrictions a clause prohibiting the resubdivision of any lot within the development except where in compliance with these regulations.
