Section 674:36 Subdivision Regulations.
I. Before the planning board exercises its powers under RSA 674:35, the planning board shall adopt subdivision regulations according to the procedures required by RSA 675:6.
II. The subdivision regulations which the planning board adopts may:
(a) Provide against such scattered or premature subdivision of land as would involve danger or injury to health, safety, or prosperity by reason of the lack of water supply, drainage, transportation, schools, fire protection, or other public services, or necessitate the excessive expenditure of public funds for the supply of such services;
(b) Provide for the harmonious development of the municipality and its environs;
(c) Require the proper arrangement and coordination of streets within subdivisions in relation to other existing or planned streets or with features of the official map of the municipality;
(d) Provide for open spaces of adequate proportions;
(e) Require suitably located streets of sufficient width to accommodate existing and prospective traffic and to afford adequate light, air, and access for firefighting apparatus and equipment to buildings, and be coordinated so as to compose a convenient system;
(f) Require, in proper cases, that plats showing new streets or narrowing or widening of such streets submitted to the planning board for approval shall show a park or parks suitably located for playground or other recreational purposes;
(g) Require that proposed parks shall be of reasonable size for neighborhood playgrounds or other recreational uses;
(h) Require that the land indicated on plats submitted to the planning board shall be of such character that it can be used for building purposes without danger to health;
(i) Prescribe minimum areas of lots so as to assure conformance with local zoning ordinances and to assure such additional areas as may be needed for each lot for on-site sanitary facilities;
(j) Include provisions which will tend to create conditions favorable to health, safety, convenience, or prosperity; and
(k) Encourage the installation and use of solar, wind, or other renewable energy systems and protect access to energy sources by the regulation of orientation of streets, lots, and buildings; establishment of maximum building height, minimum set back requirements, and limitations on type, height, and placement of vegetation; and encouragement of the use of solar skyspace easements under RSA 477.
(l) Provide for efficient and compact subdivision development which promotes retention and public usage of open space and wildlife habitat, by allowing for village plan alternative subdivision as defined in RSA 674:21, VI.
(m) Require innovative land use controls on lands when supported by the master plan.
(n) Include provision for waiver of any portion of the regulations. The basis for any waiver granted by the planning board shall be recorded in the minutes of the board. The planning board may only grant a waiver if the board finds, by majority vote, that:
(1) Strict conformity would pose an unnecessary hardship to the applicant and waiver would not be contrary to the spirit and intent of the regulations; or
(2) Specific circumstances relative to the subdivision, or conditions of the land in such subdivision, indicate that the waiver will properly carry out the spirit and intent of the regulations.
III. The subdivision regulations of the planning board may stipulate, as a condition precedent to the approval of the plat, the extent to which and the manner in which streets shall be graded and improved and to which water, sewer, and other utility mains, piping, connections, or other facilities shall be installed. The regulations or practice of the planning board:
(a) May provide for the conditional approval of the plat before such improvements and installations have been constructed, but any such conditional approval shall not be entered upon the plat.
(b) Shall provide that, in lieu of the completion of street work and utility installations prior to the final approval of a plat, the planning board shall accept a performance bond, irrevocable letter of credit, or other type or types of security as shall be specified in the subdivision regulations; provided that in no event shall the exclusive form of security required by the planning board be in the form of cash or a passbook. As phases or portions of the secured improvements or installations are completed and approved by the planning board or its designee, the municipality shall partially release said security to the extent reasonably calculated to reflect the value of such completed improvements or installations. Cost escalation factors that are applied by the planning board to any bond or other security required under this section shall not exceed 10 percent per year. The planning board shall, within the limitations provided in this subparagraph, have the discretion to prescribe the type and amount of security, and specify a period for completion of the improvements and utilities to be expressed in the bond or other security, in order to secure to the municipality the actual construction and installation of such improvements and utilities. The municipality shall have the power to enforce such bonds or other securities by all appropriate legal and equitable remedies.
(c) May provide that in lieu of the completion of street work and utility installations prior to the final approval of the plat, the subdivision regulations may provide for an assessment or other method by which the municipality is put in an assured position to do said work and to make said alterations at the cost of the owners of the property within the subdivision.
