The minimum gross area of a tract of land to be developed for a townhouse is two acres.

Where the area of the development tract is five or more acres, the maximum permitted density is six dwelling units per acre.

Where the area of the development tract is less than five acres, the density may be increased to eight dwelling units per acre at the discretion of the Planning Board when the development is consistent with the minimum bulk standards set forth herein so as to preserve open space and provide for a better designed development consistent with planning standards and consistent with adjacent land use or potential development.

The maximum number of dwelling units permitted for any development tract shall be calculated by multiplying the total area of the tract in acres by the permitted density. Any fractional number of units shall be treated as one unit when such fractional number exceeds 0.5.

Where a subdivision or site plan is required, this article shall require that the applicant provide for an organization for the ownership and maintenance of any common open space for the benefit of owners or residents of the development if said open space is not dedicated to the municipality or other governmental agency. Such organization shall not be dissolved and shall not dispose of any open space for the benefit of such development, and thereafter such organization shall not be dissolved or dispose of any of its open space without first offering to dedicate the same to the Borough of Glen Rock.

In the event that such organization shall fail to maintain the open space in reasonable order and condition, the administrative officer designated by resolution to administer this section may serve written notice upon the owners of the development, setting forth the manner in which the organization has failed to maintain the open space in reasonable condition, and said notice shall include a demand that such deficiencies of maintenance be cured within 35 days thereof and shall state the date and place of a hearing thereon, which shall be held within 15 days of the notice. At such hearing, the designated municipal body or administrative officer may modify the terms of the original notice as to deficiencies and may give a reasonable extension of time not to exceed 65 days within which they may be cured. If the deficiencies set forth in the original notice or in the modification thereof shall not be cured within said 35 days or any permitted extension thereof, the Borough, in order to preserve the open space and maintain the same for a period of one year, may enter upon and maintain such land. Said entry and maintenance shall not vest in the public any rights to use the open space, except when the same is voluntarily dedicated to the public by the owners. Before the expiration of said year, the designated Borough body or officer, as the case may be, shall, upon its initiative or upon the request of the organization therefor responsible for the maintenance of the open space, call a public hearing upon 15 days' written notice to such organization and to the owners of the development to be held by such Borough body or officer, at which hearing such organization and the owners of the development shall show cause why such maintenance by the Borough shall not at the election of the Borough continue for a succeeding year. If the designated Borough body or officer shall determine that such organization is ready and able to maintain said open space in reasonable condition, the Borough may, in its discretion, continue to maintain said open space during the next succeeding year, subject to a similar hearing and determination in each year thereafter. The decision of the Borough body or officer in any such case shall constitute a final administrative decision subject to judicial review.

If a municipal body or officer is not designated by resolution to administer this section, the governing body shall have the same powers and be subject to the same restrictions as provided in this section.

The cost of such maintenance by the Borough shall be assessed pro rata against the properties within the development that have a right of enjoyment of the open space, in accordance with the assessed value at the time of imposition of the lien, and shall become a lien and tax on said properties and be added to and be a part of the taxes to be levied and assessed thereon and enforced and collected with interest by the same officers and in the same manner as other taxes.

Height. No building shall exceed a maximum of 2 1/2 stories or 35 feet in height, whichever is the lesser.

Setbacks from street. No building shall be closer than 25 feet from any private road or closer than 50 feet from any public street. No townhouse shall be erected within 140 feet of Harristown Road or Doremus Avenue.

Space between buildings. No building shall be closer than 20 feet from the side of any building or closer than 50 feet from the front or rear of any building on the same development tract.

Rear yard setback. No building shall have a rear yard area less than 30 feet in depth.

Tract perimeter setback. No building shall be closer than 30 feet from any residential property line or closer than 20 feet from a nonresidential property line.

Total impervious coverage. Not more than 50% of the total tract area shall be covered by any impervious material, including but not limited to building structures, roads, driveways, parking areas, patios, walkways, game areas, swimming pools and the like.

Building coverage. Not more than 25% of the total tract area shall be covered by any above-grade buildings or structures.

Buffer areas. Those setbacks required at the tract perimeter listed in Subsection E(5) above shall be landscaped areas with native vegetation, together with trees, shrubs and fencing as approved by the Planning Board. Off-street parking and recreational facilities are not permitted in the buffer area. In no event shall a buffer area be less than 10 feet in depth.

Individual townhouse units may be combined into one building, provided that said overall structure shall not contain more than five townhouse units.

No such group of townhouses shall exceed a length of 120 feet, and no one unit shall have a width narrower than 20 feet and a minimum living space of 1,500 square feet.

No more than two adjacent townhouse units shall be constructed without providing a staggered front building wall offset of not less than five feet.

No rear yard shall be adjacent to any front yard.

Each townhouse shall not have less than two means of ingress and egress into each dwelling unit.

Each townhouse shall have no less than two walls with window exposure.

Overall design, both as to architectural features and construction materials, shall be subject to review and approval by the Planning Board in order to avoid excessive similarity or dissimilarity and to preserve property values within the development and for adjacent developments.
