ARTICLE I
Purpose

§ 221-1. Purpose.

A.  These regulations are adopted in accordance with New Hampshire Revised Statutes Annotated 674:35 - 42 to provide against such scattered or premature subdivision of land as would involve danger or injury to health, safety or prosperity by reason of lack of water supply, drainage, transportation, schools, fire department or other public services, or necessitate an excessive expenditure of public funds for the supply of such services.

B.  These regulations are to provide for the development of the municipality and its environs; for the proper arrangement and coordination of streets within subdivisions in relation to existing or other planned streets; for open space of adequate proportions; for suitably located streets within sufficient width to accommodate existing and prospective traffic; for adequate lighting; and for access of emergency equipment.

C. These regulations provide that the land indicated on plats submitted shall be of such character that it can be used for building purposes unless otherwise specified and generally shall include provisions which will tend to create conditions favorable to health, safety, convenience and prosperity.

ARTICLE II
Statutory Authority
§ 221-2. Statutory authority.
Pursuant to the authority vested in the Fitzwilliam Planning Board by the voters of the Town of Fitzwilliam by vote of the Town Meeting, March 10, 1970, and in accordance with the provisions of RSA 674:35 - 42, the Fitzwilliam Planning Board adopts the following regulations governing the subdivision of land in the Town of Fitzwilliam, New Hampshire.

ARTICLE VI
General Requirements

§ 221-21. Compliance with other laws; survey to be provided.
        A. All subdivision plats shall comply with the following laws, rules and regulations:
                (1) All applicable statutory provisions.
                (2) The Town Zoning Ordinance, building codes and all other applicable laws of the town.
                (3) The Master Plan, Official Map and other officially adopted plans of the town.

(4) Any regulations of the New Hampshire Water Supply and Pollution Control Commission, New   
Hampshire Water Resources Board, New Hampshire Department of Public Works and Highways and other appropriate state agencies.
B. The Board shall require the developer to provide it with a transit survey where, in the Board's opinion, accuracy normally  involved in such a survey is necessary to determine that the proposed plat meets all applicable requirements and conditions contained in these regulations and, if so, show error of closure.


§ 221-22. Character of land.
Land of such character that it cannot he safely used for building purposes because of exceptional danger to health and peril from fire, flood or other menace shall not be platted for occupancy nor for such other uses as may increase danger to health, life or property or aggravate flood hazard until appropriate measures are taken by the subdivider to eliminate such hazards. No natural drainageway shall be obstructed unless adequate means are taken to provide for the runoff for peak conditions. The area of buildable land must be of such size as to meet the specified requirements in the land ordinances.

§ 221-23. Scattered or premature development.
        A. Purpose. The purpose of this section is to provide against scattered or premature subdivision of land.
B. Causes. The following items shall be considered in determining whether the proposed subdivision is scattered    
           or premature.  The subdivider may be required to have studies made under guidelines established by the    
           Planning Board to determine the effect  that the proposed subdivision may have:

                (1)  Distance from nearest elementary school.
                (2)  Capacity of school system and effect on school bus transportation.
                (3)  Adequacy of access street(s) and/or sidewalks.
                (4)  Adequacy of water supply for domestic and fire fighting purposes, including available water holes
                     suitable for pumping.
                (5)  Potential health problems due to on-site sewage systems and inadequate water supply.
                (6)  Potential fire protection problems due to location and/or special conditions relative to type of use.

(7)  Potential special policing problems.

(8)  Potential drainage problems both on the site and downstream.

(9)  Necessitating excessive expenditure of public funds.

                (10)  Other potential problems within the meaning of the purpose of this section as stated in Subsection A.

C.  Improvements. If it is determined by the Planning Board that the proposed subdivision is scattered or premature unless special on and off-site improvements are made, the Planning Board may require the subdivider to make said improvement prior to, or as a condition of, approval of the subdivision. These improvements may consist of, but need not be limited to, the following:

1)   Improve any access street to the subdivision to the appropriate street standards if such access would     
       otherwise be  inadequate, provided that the town owns or provides the right-of-way.

(2)   Extend the public water and/or sewer system(s) if either or both are within three thousand (3,000) feet
        of the subdivision, provided that the subdivision serves or potentially can serve twelve (12) or more
        lots.

                (3)   Build or reconstruct sidewalks on any access streets where potential increase in pedestrian traffic will
                      occur, provided  that the town owns or provides the right-of-way.

                (4)   Construct static water supplies (fire ponds) with dry hydrants for fire protection. Provide traffic signals
                      at intersection and rebuild intersection in the immediate area of the proposed subdivision if such                
                      intersection would otherwise be inadequate, provided that the town owns or provides the right-of-way,
                      or give to the town easements or land for rights-of-way.

        D. Phasing of subdivisions. As an alternative to making the studies and/or improvements as required by this   
           section, the subdivider  may propose to develop his subdivision in stages.

This may be approved by the Planning Board if the town and/ or school district have plans to make public improvements and a schedule to implement these improvements so that the various stages of the subdivision will not then take place until the relative public improvements are scheduled. If improvements involve roadways, the Board can require bonding to cover improvements.

221-24. Lot layout and improvements.

A.  Lot size, width, depth, shape and orientation shall be appropriate for the location of the subdivision and use contemplated, with particular attention to purity of water and waste disposal.

B.  Lots shall be laid out and graded to eliminate flood or stagnant water pools. No water shall be permitted to run across the street on the surface but shall be directed into catch basins, if available, or otherwise into ditches, and shall be piped underground in a pipe of not less than twelve (12) inches in diameter, or such size as may be deemed necessary by the Road Agent.

C.  It shall be the responsibility of the subdivider to provide the Board with adequate information to prove that the area of each lot is adequate to permit the installation and operation of individual sewage disposal system (septic tank and leach field or dry well, but not a cesspool), except where public sewer systems are available, and to prove that the area of each lot is adequate to permit the installation and operation of individual on-site water systems, except where a public or common water system is available. Whenever required by the Board in order to establish the adequacy of the sew-age disposal system, a series of percolation tests shall be made in the subdivision in accordance with the New Hampshire Water Supply and Pollution Control Manual titled "Guide for the Design, Operation and Maintenance of Small Sewage Disposal systems."

Such easements shall have satisfactory access to existing or proposed public ways. Watercourses proposed for public control shall have a permanent easement of not less than twenty (20) feet.

F.   All proposed drainage facilities and culverts shall be installed. Natural watercourses shall be cleaned and increased in size where necessary to take care of storm runoff. Drainage swales below center-line grade shall be constructed in the street right-of-way on both sides of the paved roadway.

G.  Monuments constructed of concrete or stone at least four (4) inches wide on the top and at least thirty (30) inches long shall be set at all block corners and iron pins or equivalent markers at all lot corners. Two (2) bench marks of the same description as the monuments shall be set at opposite ends of the subdivision whose tops are at an even foot in reference to the United States Geological Survey datum plan where practical or of an assumed datum where the preceding is not feasible.

H.   In examining and passing upon a proposed subdivision, the Board may make recommendations to the subdivider relating to earth movement and retention of natural cover in order to preserve the natural beauty of Fitzwilliarn and its environment.

I.    Performance bond to include lot improvements or surety shall include an amount to guaranty completion of all requirements contained in the above subsections of the regulations, including but not limited to soil preservation, final grading, lot drainage and all other lot improvements required by the Planning Board.

§ 221-25. Street layout.

A.  The roadway shall be graded to the final grade in accordance with the profile and cross section submitted.

B.  Streets shall be logically related to the topography so as to produce usable lots, reasonable grades and safe intersections in appropriate relation to the proposed use of the land to be served by such streets; where practicable, lots shall be graded toward the ditch line of the streets; where not practicable, adequate provisions shall be made to control the drainage of each lot by an adequate stormwater system, subject to approval of the Road Agent or Town Engineer.

C.  The arrangement of streets in the subdivision shall provide for the continuation of the principal streets in adjoining subdivisions or for their proper projection when adjoining property is not subdivided and shall be of a width at least as great as that of such existing connecting streets, but in no case less than that required under Subsection D below.


D.  No street or highway right-of-way shall be less than fifty (50) feet in width and may be required to be more if a greater street width is warranted in the opinion of the Board. Existing streets shall be widened as if they were new streets, with one- half (1/2) of the additional widening to be required on each side. In addition, the travel surface of the road is required to be thirty (30) feet. Streets entering opposite sides of another street shall be laid out either directly opposite one another or with a minimum offset of one hundred twenty-five (125) feet between their center lines.


E.  Except where future connections may be possible, dead-end streets shall not, in general, exceed six hundred (600) feet in length and shall be provided with a turnaround roadway at the closed end with a minimum radius of sixty (60) feet from the center to the outside edge of the right-of-way.

F.  No horizontal curves shall have a center-line radius of less than one hundred fifty (150) feet, except turnarounds on a dead-end street. For changes in grade exceeding three percent (3%), a vertical curve shall be provided ensuring a minimum sight distance of one hundred fifty (150) feet.

G.  Grades of all streets shall conform in general to the terrain and shall so far as practicable not exceed ten percent (10%). No street  shall have a grade of less than one percent (1%).

H.  The width of blocks shall not be less than four hundred (400) feet, nor shall the length exceed one thousand two hundred (1,200)    feet.

A clear line of sight of at least one hundred (100) feet shall be provided at all intersections at an  eye height of three and seventy-five hundredths (3.75) feet.

K.  Streets which join or are in alignment with streets abutting on neighborhood properties shall bear the same name. Names of new streets shall not duplicate nor bear a phonetic resemblance to the names of existing streets within the Town of Fitzwilliam and shall be subject to the final approval of the Board of Selectmen.

221-26. Street construction and improvements.

A.  Road construction, including pavement and drainage facilities, curbs and sidewalks, when required, shall be installed and constructed with standard specifications and in all cases must be constructed under the supervision of the Road Agent.

B.  The roadway shall be constructed in accordance with the following specifications:

(1)  All topsoil, loam, clay, muck and stumps and other improper road foundation material must be removed from the limits of the roadbed to a depth of at least twelve (12) inches.

SUBDIVISION OF LAND

NEW HAMPSHIRE DEPARTMENT OF PUBLIC WORKS AND HIGHWAYS
SUGGESTED MINIMUM DESIGN STANDARDS FOR RURAL SUBDIVISION STREETS

These are suggested minimum design standards to be followed in the absence of local subdivision controls. Every effort should be made to exceed these minimums wherever possible. The circumstances of topography and other physical factors may require an occasional exception to these standards; however, the Selectmen should exercise reasonable judgment before granting such variances.

1. GENERAL STREET PLAN Approval of the general development street plan should be required before allowing construction of small integral phases of the plan.

2. STREET LAYOUT Streets shall be laid out so as to intersect at right angles, as nearly as possible, and no street shall intersect another at less than sixty degrees (60'). Property lines at street intersections shall be rounded to provide for a property-line radius of not less then twenty (20) feet. Streets shall be continuous and in alignment with existing streets as far as possible.

3. DEAD-END STREETS Dead-end streets, designed to be so permanently, shall not be longer than five hundred (500) feet and shall be provided with a turnaround having an outside roadway diameter of at least one hundred (100) feet.

4. STREET NAMES All streets shall be named without duplication with other streets in town.

5. RIGHT-OF-WAY The minimum width of a right-of-way shall be fifty (50) feet. A greater width may be required for arterial and collector streets.

6. HIGHWAY RIGHT-OF-WAY BOUNDS Highway bounds, of a type approved by the Board of Selectmen, shall be installed at all intersections of streets, at all points of change in direction and at any other points the Board may deem necessary to designate the street lines.

7. ALIGNMENT No street shall be constructed with a curvature of less than a two-hundred-fifty-foot radius [twenty-two and nine- tenths degrees (22.9')].

8.  GRADES   Street grades. where feasible, shall not exceed ten percent (10%) nor shall be any less than five-tenths percent (0.5%).

9.  CONSTRUCTION SUPERVISION   Construction of the road- way, drainage facilities, sidewalks, curbs and all other elements of  the highway must be done under the supervision of, and with the approval of, the Board of Selectmen.

10. CLEARING   The entire area of each street shall be cleared of all stumps, brush, roots, boulders and like material and all trees not  intended for preservation.

11. SUBGRADE PREPARATION   All loam and other yielding material shall be removed from the roadway and replaced with  suitable fill material. All boulders and ledge shall be removed to a uniform cross section depth of not less than twelve (12) inches below the subgrade and replaced with sand and gravel.

12. DRAINAGE   Surface water shall be disposed of by means of culverts of sufficient capacity at watercourses as determined by  standard hydraulic design methods and by construction of a longitudinal storm drainage system whenever required to relieve water  in the ditch sections. Construction shall be in accordance with New Hampshire Standard Specifications, 1969, Sections 603 and 604.

13. GRAVEL BASE   All streets shall be constructed with a mini- mum of twelve (12) inches of gravel per New Hampshire Standard  Specifications, 1969, Section 304.

14. ASPHALT SURFACE   The asphalt surface may be a bituminous surface treatment, Specification Section 410, or hot   bituminous pavement, Section 403, as required by the Selectmen. The minimum width should be twenty (20) feet for up to three  hundred (300) vehicles per day, twenty-two (22) feet for three hundred (300) to six hundred (600) vehicles per day and twenty-four (24) feet for over six hundred (600) vehicles. A forty-four-foot wide pavement may be required in areas where on-street  parking is expected. Angle parking shall not be allowed.

15. GRAVEL SURFACE   In unusual cases of low traffic volumes where the Selectmen feels an asphalt surface is not required, the total usable roadway width shall be a minimum of twenty-eight (28) feet so that the ultimate design may be a twenty-foot asphalt surface with four-foot gravel shoulders.

16. BRIDGES On stream crossings of ten (10) feet or more span, the structure shall be designed to H15-S20 loading (American Association of State Highway and Transportation Officials specifications). The minimum roadway width shall be twenty-four (24) feet.

17. GRAVEL SHOULDERS A four-foot gravel shoulder, equal to the base course depth, shall be constructed adjacent to all twenty- , twenty-two- and twenty-four-foot asphalt surfaces.

18. SIDEWALKS Sidewalks of two-inch-thick asphalt, on a four- inch gravel base, not less than four (4) feet in width and no closer than twenty-two (22) feet to the street center line, shall be constructed on one or both sides of the street when, in the opinion of the Board, such sidewalks are necessary.

19. EROSION CONTROL Erosion shall be controlled by placing mulch or matting on all surfaces disturbed by construction of the roadway and on all other surfaces where there is danger of eroded material being carried to the roadway area.

20. UTILITIES Utility poles should be kept close to the right-of- way line, in no case closer than the ditch line and always well back of a curb. Water and sewer mains should be constructed outside the surface area and preferably outside the ditch line.

21. SAFETY Safety is an important factor on all roadway improvements. On development roads, it may not be possible or practical to obtain obstacle-free roadsides, but every effort should be made to provide clear areas within the maintenance limits. The use of flatter slopes, the use of guardrails where necessary and the use of warning signs are other safety factors to be considered.

22. MINIMUM STANDARDS The use of more liberal values than these minimum standards is recommended. For additional guidance and design of local development roads and streets with high volumes of traffic, reference should be made to the New Hampshire Department of Public Works and Highways, Minimum Rural Highway Design Standards.
