(2)

In the CR-3A, MHR-8 and MFR districts, dwelling units within a group development may be arranged in groups or clusters. Each group or cluster shall abut a street; however, each dwelling unit within such a group or cluster need not so abut, provided that:

(a)

Each dwelling unit is accessible by means of a private street to service and emergency vehicles.

(b)

The standards of design and construction for private streets meet applicable town specifications for public streets unless modified by the approved site plan.

(c)

The location, design and construction of all utilities meet all applicable specifications and are adequate to serve the needs of the group or cluster.

(d)

The procedures for the preservation and maintenance of private streets, pedestrian ways and common open space comply with all applicable laws.

C.

Rural Cluster Subdivision.

(1)

Definition. A rural cluster subdivision is a residential development in the R-R District that:

(a)

Helps retain viable agriculture and/or open space;

(b)

Minimizes land use conflicts;

(c)

Provides for recreational and/or habitat corridors through linked open space networks;

(d)

Achieves flexibility, efficiency and cost reduction in the provision of services and infrastructure; and

(e)

Does not rely on central sewer facilities.

(2)

Application Requirements.

(a)

At the time of application for a rural cluster subdivision, in addition to all subdivision application materials required in accordance with § 4-4-2 of the subdivision regulations, the petitioner shall submit a site analysis map.

(b)

The purpose of the site analysis map is to ensure that the important site features have been adequately identified prior to the creation of the site design, and that the proposed open space will meet the requirements of this Section. The site analysis map shall include the following features:

(i)

Property boundaries;

(ii)

All streams, rivers, lakes, wetlands and other hydrologic features;

(iii)

Topographic contours of no less than two-foot intervals unless a more precise vertical scale is available;

(iv)

General vegetation characteristics;

(v)

General soil types and areas suitable for installation of on-site wastewater treatment systems;

(vi)

The planned location of protected open space;

(vii)

Lands with protected development rights;

(viii)

Existing roads and structures; and

(ix)

Potential connections with existing open space and trails.

(3)

Development Review Procedures. Subdivision review procedures in accordance with the Town of Amherst subdivision regulations shall apply to all cluster developments.

(4)

Design Standards. The following standards shall apply to all developed areas within a rural cluster subdivision.

(a)

Location. The developed area shall be located outside the designated open space area.

(b)

Development Pattern. Within the developed area, development of residences and infrastructure shall accommodate, to the extent possible, existing natural features, including site topography, water courses, wetlands, tree and vegetation lines and similar natural resources. Lots are not intended to be stripped out along existing rural roadways, but rather clustered in the most appropriate portion of the site for development, and surrounded by open space.

(c)

Determination of Density. Density in a rural cluster subdivision shall be determined by multiplying the gross area of the tract of land by the maximum gross density for the R-R district (one unit per three acres).

(d)

Dimensional and Density Standards. Notwithstanding the dimensional standards in § 3-2-2B a rural cluster subdivision shall comply with the development standards in the following table.

Rural Cluster Subdivision Development Standards

(f)

Agricultural Buffer.

(i)

When the developed area of a rural cluster subdivision is located adjacent to permitted agricultural activities that exist either on an abutting property or within all or part of the required open space area, a medium-impact screening buffer in accordance with § 7-2-4B(2) shall be provided.

(ii)

The Planning Board or Planning Director, as applicable, may require a higher impact screening. The final approval authority for the site plan shall consider the following characteristics in making the increased buffer determination:

a)

The location, type and scale of agricultural activities;

b)

The location of the developed area in relation to the agricultural activities;

c)

The absence of trees and understory vegetation in the proposed buffer area to provide an opaque screen of agricultural activities on abutting properties;

d)

The absence of topographic features in the proposed buffer area to provide an opaque screen of agricultural activities on abutting properties; and

e)

The presence of other significant structures used for large scale commercial or industrial activities.

(iii)

In no case shall the required buffer be less than 40 feet in width.

3-15-5.

Yard and Building Spacing: MFR-5, MFR-6 and MFR-7. In order to encourage greater flexibility and design and more attractive arrangements of buildings and greater utilization of open spaces, yard regulations for attached dwellings in the MFR-5, MFR-6 and MFR-7 districts are hereby established. Buildings shall be arranged so as to assure privacy between adjacent structures and intersecting wings of structures, appropriate setbacks from streets, parking and recreation areas and to assure adequate light and air to residents and protection to and from surrounding development. Distances shall vary in relation to the height of structures and the arrangement to other land uses and boundary lines.

A.

Definitions. For the purposes of regulating building spacing on a parcel of land in the MFR-5, MFR-6 and MFR-7 districts, the following definitions apply. Building height is defined in § 2-5-4.

[Amended 11-30-2020 by L.L. No. 17-2020]

(1)

Ha shall represent the height of building A.

(2)

Hb shall represent the height of building B.

(3)

H (Ha or Hb) shall represent the vertical distance measured from the finished grade to the mean roofline. For an explanation of how to determine the mean roof line of specific types of buildings, see below.

(a)

The highest point of the coping of a flat roof; or

(b)

The mean height between the eaves and ridge line of a gable, shed, hip or gambrel roof; or

(c)

The highest point of the roof and parapets of a mansard roof.

(4)

D shall represent the required minimum horizontal distance between any wall of Building A and the nearest wall of Building B or between a principal building and a property line as determined by the following formulae.

Description		Distance =
Building Separation — Parallel Arrangements
Buildings are parallel or within 30 degrees of being parallel and the greater sides of each building face each other across an open yard or court.		[(Ha + Hb)/2] x 1.66
Buildings are parallel or within 30 degrees of being parallel and the lesser sides of each building face each other across an open yard or court, or the lesser side of one building faces the greater side of the other building.		[(Ha + Hb)/2] x 1.5
