12-9-2: NOTES TO SCHEDULE OF REGULATIONS:
(A) See section 12-9-3, "Lot Size Averaging", of this chapter, for flexibility allowances.
(B) Minimum front yard setback is measured from the edge of the abutting right of way, based upon information and standards set forth by the city of Clinton.
(C) For all nonresidential uses allowed in residential districts, the setbacks shall equal the height of the main building, or the setbacks required in this chapter, "Schedule Of Regulations", whichever is greater.
(D) All side yards abutting upon a public street shall be considered as a front yard for setback purposes, except as may otherwise be required by this title.
(E) The minimum floor area per dwelling unit shall not include area of basements, breezeways, and porches or attached garages.
(F) The minimum livable floor area per multiple-family unit shall be in accordance with the following schedule:
Unit Type | Minimum Floor Area Required (Square Feet) |
Efficiency | 350 |
1 bedroom | 600 |
2 bedroom | 800 |
3 or more bedrooms | 1,000 |
(G) In all residential districts, the required front yard setback shall not be used for off street parking, loading, or unloading, and shall remain as open space unoccupied and unobstructed from the ground upward, except for landscaping, plant materials, vehicle access drives, or as otherwise specified by this title.
(H) Where the average setback of the buildings existing at the time of adoption of this title within one hundred fifty feet (150') on either side of the lot on which a building is proposed is less than thirty feet (30'), that average distance may be used as a minimum setback.
(I) For two-family dwellings in the R-3 one-family residential district, the following standards shall apply:
Minimum Size Per Zoning Lot: | Area: | 10,000 square feet |
Width: | 100 feet | |
Maximum Building Height: | Stories: | 2.5 |
Feet: | 25 | |
Maximum Lot Coverage: | 30 percent | |
Minimum Yard Setbacks: | Side: | 15 feet |
Rear: | 40 feet | |
Front: | 30 feet | |
(J) On a corner lot, the minimum lot area in the multiple-family residential district shall be eight thousand (8,000) square feet.
(K) The distance between any two (2) structures within a multiple-family residential development shall not be less than thirty feet (30').
(L) In the multiple-family district, the minimum side yards for multiple-family developments shall be equal to fifteen feet (15') or one-half (1/2) the height of the structure, whichever is greater.
(M) Within any yard setback or area between buildings, an area equivalent to seventy percent (70%) of any required yard or any required minimum area between buildings must be landscaped and developed as usable open space or recreation area available to the residents of the development, and further, said areas shall be kept free of all vehicular uses.
(N) In the district, front, side, or rear yards need not refer to spacing between buildings for the planned development of two (2) or more buildings on the same parcel. In such cases, the minimum distance between any two (2) buildings shall be regulated according to the length and height of such buildings and in no instance is less than thirty feet (30').
The formula for regulating the required minimum distance between two (2) buildings is as follows:
S = | LA + LB + [2 (HA + HB)] 6 |
where: | |
S | Equals required minimum horizontal distance between any wall of building A and any wall of building B or the vertical prolongation of either. |
LA | Equals total length of building A. The total length of building A is the length of that portion or portions of a wall or walls of building A from which, when viewed directly from above, lines drawn perpendicular to building A will intersect any wall of building B. |
LB | Equals total length of building B. The total length of building B is the length of that portion or portions of a wall or walls of building B from which, when viewed directly from above, the lines drawn perpendicular to building B will intersect any wall of building A. |
HA | Equals height of building A. The height of building A at any given level is the height above natural grade level of any portion or portions of a wall or walls along the length of building A. Natural grade level shall be the mean level of the ground immediately adjoining the portion or portions of the wall or walls along the total length of the building. |
HB | Equals height of building B. The height of building B at any given level is the height above natural grade level of any portion or portions of a wall or walls along the length of building B. Natural grade level shall be the mean level of the ground immediately, adjoining the portion or portions of the wall or walls along the total length of the building. |
(O) The maximum percentage of coverage shall be determined by the use and provisions of required off street parking, loading and unloading, and required yards.
(P) Off street parking shall be permitted to occupy a portion of the required front yard; provided, that there shall be maintained a minimum unobstructed landscaped setback of ten feet (10') between the nearest point of the off street parking area, exclusive of access driveways, and the front lot line.
(Q) Loading space shall be provided in the rear yard in accordance with section 12-5-12 of this title.
(R) Off street parking shall be permitted in a required side yard setback when said side yard abuts a nonresidential district.
(S) All storage shall be in the rear yard and shall be completely screened with an obscuring wall or fence, not less than six feet (6') high, or with a chainlink type fence and a greenbelt planting so as to obscure all view from any adjacent residential or business district or from a public street.
(T) In the recreation/conservation district, the requirements for minimum lot size, maximum building height, and maximum lot coverage shall not apply to educational and municipal buildings. (Ord. 867, 11-5-2001)
12-9-3: LOT SIZE AVERAGING:
Lot size averaging may be permitted by the planning commission, upon application from the proprietor, if it determines that it will provide a better relationship of lots to the topography, vegetation or other natural or manmade features. Lot size averaging is the allowance for a change in lot area and width in a development, but with the average lot area meeting the minimum area as required in this section for that particular one-family residential district.
In the case where lot size averaging is permitted, the following conditions shall be met:
(A) The number of lots shall not exceed the number allowed for the zoning district in which the development is located.
(B) Reduction of lot area or width below the minimum required for the zoning district shall not be permitted for more than one- third (1/3) of the total number of lots in the development.
(C) No lot shall have an area or width more than ten percent (10%) below that area or width required in the schedule of regulations.
(D) All computations showing lot area and the average resulting through this technique shall be indicated on the print of the preliminary plat.
(E) The submittal shall be reviewed and approved in accordance with terms of the city's subdivision regulation ordinance. (Ord. 867, 11-5-2001)
