5. 
An arrow indicating magnetic North.
8.5.9. 
Procedures; definitive land development plan. A special permit application shall be filed in accordance with the SPGA's regulations and shall be accompanied by the definitive land development plan (DLDP). The SPGA shall hold a public hearing in accordance with the provisions of Section 10.4. The Planning Board shall also hold a public hearing in accordance with its Subdivision Regulations to determine the appropriateness of any roadways in the PURD and any requested waivers from the Subdivision Regulations. The hearings may be held simultaneously, though there shall be distinct findings and votes taken in accordance with the governing laws, rules, and/or regulations. The Planning Board's endorsement of such roadway plan shall be in accordance with all provisions of its Subdivision Regulations. The DLDP shall contain, at a minimum, the same information as the PLDP including any changes made thereto and any other information requested by the Planning Board. The special permit application shall:
1. 
Be accompanied by two locus maps showing the location of the property. One shall be an enlarged section of a United States Geological Survey Map, and the other shall be a copy of the current Great Barrington Zoning Map, each indicating the location of the property by arrow or other suitable mark.
2. 
Be signed by the owner or owners of the property in question or, if the applicant is other than the owner of the property, shall be signed by the applicant and shall be accompanied by a letter from the owner authorizing the applicant to apply for the special permit. Said application shall also be accompanied by all appropriate fees. For the purposes of this section, an "applicant" shall be defined as a person, corporation, partnership or other legal entity having a legal or equitable interest in the property.
3. 
Contain elevations and floorplans of the proposed dwellings.
8.5.10. 
Decision. In addition to the criteria set forth in Section 10.4, the SPGA shall consider the following:

2. 
Usable open space or common land shall be assured and maintained in accordance with the procedures prescribed herein.
3. 
The development plan shall contain specific time periods within which development of each section of the PURD will be started. Failure to start construction within those periods may be cause for issuance of a stop-work order by the Inspector of Buildings.
8.6.1. 
General. As a temporary dwelling, one trailer, recreational vehicle, or mobile home may be permitted and used as a dwelling on any standard lot for not more than 60 days in any twelve-month period. A permit from the Building Inspector is required. The special permit granting authority may, however, allow such use for a longer period of time by special permit in hardship cases, provided that a time limit of 12 months is imposed as part of the authorization.
8.7.1. 
Purpose. The primary purposes for the open space residential development (OSRD) bylaw are the following:
1. 
To encourage the permanent preservation of open space, agricultural land, forestry land, wildlife habitat, wetlands, steep slopes and historical and archaeological resources;
2. 
To enhance existing open space resources in the Town of Great Barrington by addition of adjacent lands, linkage of trail systems or wildlife habitat in a manner that is consistent with the Town of Great Barrington's Open Space and Recreation Plan;
3. 
To encourage development that consumes less open land and conforms to existing topography and natural features better than conventional subdivision design;
4. 
To minimize the total amount of land disturbance on the site;
5. 
To allow for greater flexibility and creativity in the design of residential development;
6. 
To facilitate the construction and maintenance of housing, streets, utilities and public services in a more economical and efficient manner;
7. 
To add to the visual amenities of the area for persons passing a site of residential development or overlooking it from nearby;
8. 
To encourage construction of diversified housing.
8.7.2. 
Applicability. Only those parcels located in an R2 or R4 District shall be eligible for an OSRD special permit. An OSRD may be allowed on parcels five acres or greater. Any subdivision of a parcel of five acres or greater in size which will create more than two additional residential lots may be undertaken by special permit application to the Planning Board for an OSRD.
1. 
Parcels less than five acres require a separate finding. Any subdivision of parcels less than five acres in size for residential purposes may be undertaken by special permit as an OSRD subdivision under this section if the Planning Board finds that the potentially smaller, fragmented open space area(s) to be created and preserved in the proposed design would provide a significant benefit to the public interest.
8.7.3. 
Noncontiguous parcels. Parcels that are not contiguous shall not be eligible for special permit application as a single OSRD development, unless the Planning Board finds that the open space area(s) to be preserved in the proposed design would provide a significant benefit to the public interest.
8.7.4. 
Permitted residential uses. Residential uses permitted in OSRD developments shall be single- or two-family dwellings.
8.7.5. 
Land division. To be eligible for an OSRD special permit, the parcel(s) may be a subdivision or a division of land pursuant to MGL c. 41, § 81P.
8.7.6. 
Ownership. An OSRD may be owned under any form of ownership legally permitted in the Commonwealth of Massachusetts.
8.7.7. 
Preliminary discussion and determination of project density. Applicants must submit plans and materials for review by the Planning Board, prior to formal application for a special permit, to assist the Planning Board in making a determination regarding the maximum number of dwelling units to be permitted on the tract of land proposed for OSRD. The following items shall be submitted: a base plan and either a mathematical determination of yield or a yield plan.
8.7.8. 
Base plan. The base plan should contain sufficient information about ownership, property description, property access and natural resources to indicate the development potential of the property, and shall be prepared at an appropriate scale, based on the size of the property, to convey the information accurately. The following information should be provided on a base plan:
1. 
Boundary survey of the property showing all easements;
2. 
The names and locations of all streets providing access to and abutting the property;
3. 
Topographic information at 10 feet or three meter contour lines, including delineation of slopes of 25% or greater;
4. 
The zoning district(s) the property is located in, including all overlay districts;
5. 
The location of areas of protected open space on the subject property or abutting the property, including, but not limited to, land under a conservation restriction, agricultural preservation restriction or classified for taxation purposes under Chapter 61, Chapter 61A, or Chapter 61B of the General Laws;
6. 
The location of wetlands and vernal pools;
7. 
The location of lakes, streams, riverfront areas and other resources under the jurisdiction of the Wetlands Protection Act;
8. 
The location of land in agricultural use;
9. 
The location of land containing prime agricultural soil and soil of state and local importance, as defined in the Berkshire County, Massachusetts, Soils Rating Guide July 2002, or subsequent version, available from the Natural Resources Conservation Service;
10. 
Floodplain or floodway areas;
11. 
Sewage disposal capacity: either the location of municipal sewer mains; or evidence, as approved by the Board of Health, that the property has the capacity for on-site septic disposal as demonstrated by a representative sample of deep hole test pits and percolation test results along with evidence that the representative samples have been taken in locations that are consistent with the geology of the property;
12. 
The location of estimated, priority and core habitats as established by the Natural Heritage and Endangered Species Program of the Massachusetts Division of Fisheries and Wildlife;
13. 
North arrow and a graphic scale;
14. 
Areas believed to be developable;
15. 
Summary table indicating the total area of developable land. For the purposes of this section, developable land shall not include wetlands as defined in the Wetlands Protection Act (Chapter 131, Section 40 of Massachusetts General Laws), vernal pools, slopes of 25% or greater and areas subject to existing valid open space restrictions.
8.7.9. 
Other material. Applicants may provide other information about the development suitability of the property, opportunities for alternative designs and how the project might accomplish the intent and purposes specified herein. Form B-1, Inventory of Constraints and Opportunities, as found in the Appendix of the Planning Board's Subdivision Regulations, Chapter 240, may be used to guide the discussion and to enhance understanding of the site.
8.7.10. 
Determination of yield. Working with the Planning Board, applicants have two options to determine the maximum number of dwelling units to be permitted on a parcel(s) of land: a mathematical determination of yield; or a yield plan.
1. 
Mathematical determination of yield. The mathematical determination of yield is intended to be a simplified method to determine the maximum number of dwelling units allowed on the parcel(s). The mathematical determination of yield is calculated as follows:
Step 1: Determine presumed area of developable land. Based on the material shown on and submitted with the base plan, the applicant shall work with the Planning Board to determine the presumed area of developable land.
Step 2: Calculate presumed amount of developable land. The mathematical determination of yield assumes 30% of the developable land area is needed for infrastructure improvements. For the purposes of the mathematical determination of yield, the presumed area of developable land determined in Step 1 is multiplied by 70% to indicate the total amount of developable land.
Example: On a 100-acre parcel, 60 acres are determined, after working with the Planning Board, to be the presumed area of developable land. The presumed amount of developable land is 42 acres (60 x 0.7).
Step 3: Calculate the maximum number of allowable lots. The maximum number of allowable lots is determined by taking the presumed amount of developable land and dividing it by the minimum lot area requirement in the zoning district as shown in Section 4.0, Schedule of Dimensional Requirements.
Example: From the example above, the amount of developable land is 42 acres. The minimum lot size in the R4 District is two acres. Therefore, the maximum number of allowable lots is 21 (42 ÷2.0).
2. 
Yield plan. A yield plan is intended to indicate the number of lots the applicant believes would be attainable if the parcel(s) were developed as a conventional subdivision consistent with Great Barrington's Subdivision Rules and Regulations. In addition to the information shown on the base plan, the yield plan should show, using an appropriate scale, the locations of all streets and easements within the proposed development and the proposed layout of lots indicating the lot size, frontage and setbacks for all lots shown. The yield plan should contain sufficient information to indicate the plan could comply with the Great Barrington Subdivision Rules and Regulations. This number of lots will be subject to validation once the applicant has obtained the applicable development permits and submitted suitable engineering studies necessary to substantiate the developable area of land.
8.7.11. 
Determination of final project density. Based on the mathematical determination of yield or yield plan submitted to the Planning Board, the Planning Board shall determine the maximum number of lots that could be achieved on the parcel(s), and shall notify the applicant in writing of its decision within 30 days of such submission.
1. 
The maximum number of lots shall be used in conjunction with the proposed amount of protected open space to determine the final project density. The greater the area proposed for protected open space, the greater the allowed increase in final project density.
2. 
The minimum area of the protected open space must be 50% of the area of developable land. When the 50% minimum area of the developable land is dedicated to protected open space, the permitted density allowed under the OSRD special permit may not exceed 125% of the number of lots determined by the mathematical determination of yield or yield plan.
3. 
At this point, the maximum number of lots becomes the maximum number of dwelling units permitted, whether or not they are constructed as one- or two-family dwellings.
Example: Using the above example, the maximum number of allowable lots, as determined by the mathematical determination of yield, is 21. With a dedication of 50% of the developable land area as protected open space the applicant could construct 26 dwelling units (21 x 1.25 = 26.25 [ignore fractions] = 26).
4. 
For every 1% above 50% of the total area of developable land dedicated to protected open space, the permitted maximum density allowed under the OSRD special permit may, at the sole discretion of the Planning Board, be increased 2% to a maximum density bonus of 50%.
Example: Using the example developed previously, if instead of the minimum 50% of the area of developable land dedicated to protected open space that percentage is increased to 62.5% then the applicant could construct 31 dwelling units (21 x 1.5 = 31.5 [ignore fractions] = 31).
8.7.12. 
Design criteria and considerations.
1. 
Protected open space requirements. Consistent with the purposes of this bylaw, the Planning Board must be satisfied, in its sole discretion, that the characteristics of the open space offered for preservation ensure an appropriate benefit to the public interest in exchange for the bonus provisions of OSRD design.
2. 
Site context. Consistent with the purposes of this bylaw, the Planning Board must be satisfied, in its sole discretion, that the proposed development is consistent with the context of the neighboring property, considering such items as physical, transportation and cultural connections to surrounding land uses and activities.
3. 
Grouping of structures. There shall be grouping of principal structures and their associated accessory structures. This grouping must be based upon some common unifying and recognizable organizing principle, such as a courtyard, driveway, view orientation or parking area that defines the inter-relationship of the structures.
4. 
Protected open space requirement. A minimum of 50% of the developable land area shall be protected open space.
Example: On a parcel with 100 acres of developable land, a minimum of 50 acres must be left as protected open space.
5. 
Contiguity of protected open space. Protected open space shall be contiguous to the maximum extent practicable, i.e., connected to other open space within or adjacent to the proposed OSRD development. The Planning Board may waive this requirement for all or part of the required protected open space where it finds, in its sole discretion, that allowing noncontiguous open space will promote the goals of this bylaw.
6. 
Areas used for rights-of-way, buildings, courtyards, parking, pools, tennis courts or other uses that create impervious surfaces or other intensive uses shall not be counted towards the total open space acreage required to be preserved, even though they may be held in common ownership by a single entity such as a homeowners' association and restricted from further development.
7. 
Pedestrian and bicycle circulation. Trails and bicycle paths may be provided to link residences with recreation facilities (including parkland and open space) and adjacent land uses where appropriate. Open space dedicated to these uses may be counted towards the total protected open space acreage requirement.
8. 
Setbacks and protected open space. Required setbacks may, at the Planning Board's discretion, be counted towards the required protected open space provided that counting the setback as open space furthers the purposes of this bylaw.
9. 
Areas devoted to wastewater disposal, stormwater management systems and wellhead protection serving the OSRD may be counted towards the total open space acreage required to be preserved. The area (to top of berm) of stormwater management devices, such as retention and detention ponds, may be counted towards the total open space acreage required to be preserved.
8.7.13. 
Ownership of protected open space. The protected open space shall be conveyed to:
1. 
The Town or its Conservation Commission and/or Parks Commission; or
2. 
A nonprofit organization, the principal purpose of which is the conservation of open space for the purposes set forth by the applicant; or
3. 
The homeowners' association. Maintenance of open space owned by a homeowners' association shall be permanently guaranteed by an arrangement providing for mandatory assessments for maintenance expenses to each ownership interest. Each such association shall be deemed to have assented to allow the Town to perform maintenance of such open space and associated facilities, if the association fails to provide adequate maintenance, and shall grant the Town an easement for this purpose. Before the Town performs such maintenance, the Town shall first provide 14 days' written notice to the association as to the inadequate maintenance, and, if the association fails to complete such maintenance, the Town may perform it at the association's expense. Each individual deed and the trust or articles of incorporation shall include language designed to effect these provisions. Documents creating such corporation, trust or association shall be submitted to the Planning Board for approval, and shall thereafter be recorded with the Registry of Deeds.
