Environmental Constraints Cluster Option. Land within this Rural Conservation Residential District may be subdivided in a cluster subdivision in accordance with the following requirements: The total number of lots within the subdivision shall be determined by dividing the total acreage by five acres per lot.
This total number of lots may be then subdivided within the total tract in accordance with the following net residential site reduction standards provided that the balance of the tract is retained in perpetual open space by either a homeowners association in accordance with the standards set forth in Subsection
18-5.4, or dedicated to the Township of Sparta for open space, conservation, recreation and/or public school purposes consistent with the Master Plan. The net size of the residential sites may be reduced as follows and in accordance with the standards set forth in Subsection
18-5.6.
1. Least Restricted. One unit per two acres.
2. Moderately Restricted. One unit per three aces.
3. Severely Restricted. One unit per five acres.
4. Newly Created Lot or Subdivision Lot. Any newly created lot or subdivided lot in a major or minor subdivision shall be at least five acres. The five acre lot may be clustered, however, in accordance with this subsection.
5. Minimum Residential Site Size. Minimum residential site size within any cluster development under this subsection shall be two acres of least restricted land. Constraint calculations shall not be required where the proposed residential site to be created is five acres or more.
6. Open Space or Public Dedication. No residential site shall be greater than five acres. All land not included in the net residential sites shall be dedicated to the public or preserved in open space pursuant to Subsection
18-5.4. If net residential sites are created which are less than five acres, the open space or public lands dedication for said clustered net residential site shall be equal to or greater than five acres minus the size of the net residential site.
7. Contiguity of Open Space/Public Dedication. Not less than 40% of the gross acreage of the tract shall be reserved for permanent common open space. All open space areas and/or public dedication areas (open space areas) shall be contiguous with the subdivision. All open space areas shall have access from a public street and frontage of at least 100 feet on a public street. The open space shall abut at least 50% of the side or rear of the net residential sites. At least 5% of the open space land shall be least restricted and moderately restricted land.
8. The open space shall be planned and designed to provide for interconnection to nearby or adjacent public land and planned or possible future open space as per the Master Plan.
9. Required Conditions. The following requirements shall be complied with in the environmental constraints cluster option:
(a) Height. The height of the principal structure shall not exceed 2 1/2 stories and 38 feet in height as defined in the chapter.
(b) Front Yard. There shall be a front yard of not less than 75 feet.
(c) Side Yard. There shall be two side yards, each of which shall have a minimum of 30 feet.
(d) Rear Yard. There shall be a rear yard of at least 75 feet.
(e) Minimum Lot Area. The minimum lot area for determination of total development density within any minor or major subdivision shall be five acres for each lot.
(f) Land Coverage. The maximum impervious coverage shall be 18% for lots up to two acres in size and 4% additional coverage for all lot area greater than two acres. For example, a sample calculation for a three acre lot would be as follows:
(1) First two acres: 87,120 square feet x 0.18 = 15,682 square feet permitted impervious coverage.
(2) Additional one acre: 43,560 square feet x 0.04 = 1742.40 square feet additional permitted impervious coverage.
(3) Total Permitted Impervious Coverage: 17,424.40 square feet.
(g) Minimum Frontage. Minimum frontage at the right-of-way line shall be 135 feet.
(h) Minimum Width. Minimum width of the building line shall be 175 feet. Minimum frontage at the turnaround at the end of a cul-de-sac shall be 100 feet. The minimum width of the building line of a cul-de-sac lot shall be 150 feet.
