SECTION V - PROCEDURE FOR THE SUBMISSION AND APPROVAL OF PLANS.

 

 

A.        Preliminary Conceptual Consultation (Optional)

1)       The applicant may request a meeting with the Board to discuss a proposal in conceptual form and in general terms.  Although this phase is strictly optional, the Board strongly suggests that the applicant avail him/herself of the opportunity to resolve any issues at this early stage that might become a problem later on.  Such pre-application consultation shall be informal and directed toward:

 

a)       Reviewing the basic concepts of the proposal;

b)      Reviewing the proposal with regard to the master plan and zoning ordinance;

c)       Explaining the state and local regulations that may apply to the proposal;

d)      Preliminary conceptual consultation shall not bind the applicant or the Board.  Such discussion may occur without formal public notice, but must occur only at a posted meeting of the Board.

e)       The applicant may meet with the Planning Director and the Planning Board Engineer prior to meeting with the Board.  However the applicant needs to sign a form agreeing to pay all costs incurred by the Planning Board Engineer review.

 

B.      Submission of Completed Application (Required)

 

1)       A completed application shall be filed with the Planning Board or its designee at least 15 days before a regular meeting at which the application will be accepted.  A completed application shall consist of all the data required in Section VI of these regulations.  A completed application sufficient to invoke jurisdiction of the Board shall be submitted to and accepted by the Board only at a public meeting of the Board, with notice as required by RSA 676:4,I(d).

2)       All plans will be reviewed for completeness by the Planning Board or its designee.   If the plan is incomplete, the applicant will need to provide the missing submission items before the Planning Board will accept the application.    The Planning Board or its designee will give the applicant a form indicating whether or not the application is complete, or incomplete, in writing, within five (5) days of submission of the application.

 

 

C.        Board Action on Completed Application

 

1)       The Board shall begin consideration of the completed application within 30 days of its acceptance.  The Board shall act to approve, conditionally approve, or disapprove the accepted application within 90 days of acceptance of the application.

2)       The Board may apply to the Selectmen for an extension not to exceed an additional 90 days before acting to approve, conditionally approve, or disapprove an application.  An applicant may waive the requirement for Board action within the time periods specified in these regulations and consent to such extension as may be mutually agreeable.

3)       Approval of the application shall be certified by written endorsement on every page of the plat and signed and dated by the Chairman of the Board.  If any application is disapproved, the grounds for such disapproval shall be adequately stated in the records of the Planning Board and in written notice given to the applicant within 72 hours of the decision.

4)       An approved plan shall be recorded by the applicant with the Hillsborough County Register of Deeds within 90 days of approval, if the plan is not recorded within that time, the approval is void.  If the plan is granted conditional approval, the applicant must record the plan within 90 days after all the conditions have been met. Any subdivision plan not filed within this time frame shall be considered void.

 

 

D.      Failure of the Planning Board to Act. 

 

1)       In the event that the Planning Board does not act on an accepted application within the prescribed 90 days, the applicant may petition the Selectmen to issue an order directing the Planning Board to act within 30 days.

2)       If the Planning Board fails to act within 40 days of this directive, the Selectmen must approve the application unless they find in writing that the plan does not comply with a local regulation.  In the event the Selectmen fail to act, the applicant may petition superior court to approve the plan.

 

 

E.       Conditional Approval.

 

The Board may grant conditional approval of an application, but the plat will not be signed or recorded until all of the conditions have been met.  If the applicant has not complied with the conditions of approval within one (1) year, the approval is considered null and void and the applicant must submit a new subdivision application.  A further public hearing is not required when such conditions:

1)       Are administrative in nature;

2)       Involve no discretionary judgment on the part of the Board;

3)       Involve the applicant’s possession of permits and approvals granted by other boards or agencies, such as the Department of Transportation, or the Wetlands Board; however, any subsequent change to the plan required by such approvals would constitute grounds for a new application process.

 

 

 

F.       Expedited Review.

 

1)       The Planning Board may allow for an expedited review of applications for lot line adjustments.

2)       The completed application may be voted on at the public hearing, provided that public notice so indicates and notice to abutters and holders of conservation, preservation, or agricultural preservation restrictions shall be given in accordance with RSA 676:4,I(d).  Any abutter or holder of conservation, preservation, or agricultural preservation restrictions may be heard on the application upon request.

3)       The board may waive certain plat requirements for lot line adjustments.

8)       Escrow Account for Engineering Inspections for Subdivisions.    After an approved plan has been recorded at the Registry of Deeds, the Planning Board will instruct the Planning Board Engineer to provide an estimate of costs for engineering inspections. The subdivider must then post that amount in an escrow account with the Planning Director to be held by the Town Treasurer who may release monies at the direction of the Planning Director. If subdivider does not post the amount, no inspections will be allowed and the Planning Director is so directed by the Planning Board through virtue of this Section V-I-8 to issue a cease-and-desist stop work order on the subdivision.

SECTION X - RELEASE OF PERFORMANCE GUARANTEE 

 

A.      Upon completion of all improvements, the applicant may send by registered mail to the Town Clerk and the Planning Board a written statement that the said improvements in connection with which such bond, or deposit has been completed in accordance with the Town’s requirements.    If the Planning Board determines that said construction of installation has been completed, it shall notify the Town Treasurer that it releases the interest of the Town in such a bond or deposit and that it shall be returned to the person or persons who furnished same.   However, ten percent (10%) of the value of the bond shall be held by the Town for a period of twelve (12) months after the completion of construction and installation of the improvements.  Prior to the final release, the “as-built” plan and description shall be submitted.

 

The Planning Board shall request, approximately sixty (60) days before the expiration of the twelve (12) months, an inspection of said street or way or portion thereof by the Planning Board Engineer to determine whether or not defects have developed therein, and determine whether or not it should recommend the layout out of said street or way or portion thereof as a public way.  If the recommendation  is  in  the  affirmative,  the  Planning  Board  would  recommend to the Town that these street(s) be accepted at Town Meetings.

 

Prior to releasing the Town’s interest in a performance bond or deposit the Planning Board shall receive from the developer an Acceptance Plan (See Section XI) and from the following Town Officials written statements of approval. 

 

1)       From the Town’s Consulting Engineer (hired by Planning Board) as to construction of all ways and sidewalks, installation of monuments, street signs, traffic signs, lane pavement, lights, gutters and curbs, required grading and drainage, and planting and seeding;

2)       From the Town Engineer (hired by Planning Board) as to the installation of adequate lot drainage.

 

 

If the Planning Board determines that said construction or installation has not been completed, it shall specify to the developer, in writing, by registered mail, the details wherein said construction and installation shall have failed to comply with the required improvements.

 

 

SECTION XI - ACCEPTANCE BY THE TOWN

 

A.     The subdivider shall file with the Planning Board a final plan on tracing cloth of completed street or streets, together with proper legal descriptions for initiating an article in Town Warrant pursuant to the acceptance of the streets by the Town Meeting.   The developer shall have prepared and certified by a Registered Land Surveyor an “As-built” plan drawn with India ink on tracing cloth (size 18” x 24” or 24” x 36”) showing widths, lengths, bearings of all boundary lines of streets and easements and radii, tangents and central angles of all curves in street lines and shall show all utilities.  It shall show that all stone bounds have been set.     A blank space (4” x 8”) shall be provided on the lower right hand corner of the plan for a title block to be filled in by the developer.  The surveyor shall place a certification on the plan stating “The street (or way or portion thereof) is laid out and the bounds have been set as shown on this plan” and shall be dated, signed and the surveyor’s stamp affixed thereon.  The plan shall be submitted and signed by the Board of Selectmen.    Upon acceptance by the Town, the subdivider shall grant a deed to the Town of the streets as contained in the plan, said deed to be recorded by the Town Clerk upon acceptance of the streets by the Town meeting.

 

 

SECTION XII - DESIGN STANDARDS.

 

A.      STREETS.

 

1.       Location.

 

a.       The street system shall conform to the Master Plan, if any, of the principal streets, as adopted in whole or in part by the Board; 

b.       The creation of street layouts shall allow for proper access to adjoining property which is not yet subdivided.  Unless approved by the board, all layouts shall continue to property lines.   Street construction within these layouts may not be mandatory, but the ways shall be laid out and bounded for acceptance along with these roadways being constructed.

c.       Reserve strips which prohibit access and or contiguous streets to abutting property shall not be allowed.

d.       Streets that cannot be extended and will be permanently terminated will not have a greater centerline length than 560 feet prior to the beginning of the termination.

 

2.       Alignment.

 

a.       Streets shall be continuous and in alignment with existing streets as far as possible.  Centerline offsets of less than one hundred fifty (150) feet will not be allowed.  The subdivision street system before leaving the confines of Pelham shall connect directly with a pre-existing paved public way.  Such pre-existing paved public way shall itself, before leaving the confines of Pelham, connect with another paved public way.  Additionally, such paved ways must have the capability of reasonably serving the increased traffic that will be generated by development of the proposed subdivision.  No subdivision street shall connect with any unpaved public way.

b.       The minimum allowable centerline radius of curvature of a street shall be one hundred fifty (150) feet.  Greater radius may be required on major streets.  All plan curves must be designed and constructed at a constant radius.  Reverse curves of less than three hundred (300) feet radius shall be separated by tangents of not less than three hundred (300) feet.  Where a plan curve and vertical curve are to occur at the same point along any street, the engineer or surveyor shall certify that the sight line distance shall not be less than three hundred (300) feet from any point in either direction.

 

 

3.       Width.

 

a.       The minimum width of street rights-of-way shall be fifty (50) feet.   The Board may, however, require a greater width of right-of-way for major streets or where slopes may factor to maintain cul-de-sacs.   Cul-de-sacs shall be permitted only with approval of the Board.  When permitted, all cul-de-sacs shall terminate in turnarounds as required by the Board (See appendix ).

a.

 

4.       Grade.

 

a.   Streets shall intersect at right angles, and the grade at the intersection shall be not more than two percent (2%) for a distance of one hundred (100) feet from the intersection, or as approved by the Board; however, in no case may the grade exceed three (3%) percent at the intersection.

 

b.       The grade of streets shall be not less than one percent (1%) any more than eight percent (8%) for a major street or a grade of ten percent (10%) for a secondary street.  No street shall have a grade in excess of eight percent (8%) for a distance in excess of one thousand (1,000) feet, except that a 10% grade may be allowed at the discretion of the Planning Board where its distance is not greater than 1,000 (one-thousand) feet.    In what the Board determines to be a severe slope condition, the Board may accept waiver requests for a maximum grade of twelve percent (12%) for a distance not greater than three hundred (300) feet and not to exceed the average grade greater than ten percent (10%) for one thousand (1,000) feet provided by a professional engineer.  Changes in grade shall be accomplished by vertical curves of suitable dimensions.

 

 

5.       Monuments.

 

a.       Granite stone bounds (See Appendix) shall be installed at all intersections or streets, at all points of change in direction or curvature of streets, also at the front lot corners of each lot and along all property lines direction change where drill holes cannot be placed in existing stone walls.  The Board may require further monuments necessary to control the lines of streets.  Monuments shall be installed and shown on each plan whether or not the subdivision involves street construction.  Stone walls existing as boundaries shall not be removed or altered except to gain access to abutting properties and then shall be removed only for the minimum distance.  Care should be given for interior stone walls within the subdivision.  Boundaries to incorporate these walls in proposed future lot lines.  The Board may consider “no cut zones” to preserve the heritage of these stone walls.

 

 

6.       Signs.

 

a.       The subdivider shall provide sufficient funds for the Town to install street signs and pavement markings.

 

 

7.       Lights.

B.        LOTS

 

1.       Frontage

 

a.       All lots, except those for the use of industrial buildings, shall have at least two hundred (200) continuous feet of frontage on a publicly approved street.  A publicly approved street is a Class V street that has been approved by the Planning Board and the Town.    Streets which have been discontinued as an open highway and made subject to gates and bars by a vote of the Town, pursuant to RSA 238:2, shall not have the status of a publicly approved street and shall not be used to meet frontage requirements.  Frontage requirements cannot be met by private easements or rights-of-ways.  Lots for the use of industrial buildings shall have at least two hundred (200) continuous feet of frontage on a publicly approved street, or at least two hundred (200) continuous feet of frontage on a clearly defined fifty-foot wide privately owned right-of-way.  Whenever a lot for the use of an industrial building has its frontage on a privately owned right-of-way, all setback lines will be measured from the edge of the privately owned right-of-way.  All required frontage shall be located entirely within the Town of Pelham.  Proposed subdivision activity is not allowed to landlock another parcel.  Developers must provide at least a fifty-foot frontage to adjacent parcels when deemed necessary by the Board at locations to be approved by the Board.

 

 

2.       Street Re-Alignments.

 

a.       The front lot line of every lot shall be set back at least twenty-five (25) feet from the centerline of the publicly approved streets serving the lot.  All lots on roads having less than a fifty-foot right-of-way shall have a separate plot plan for each lot showing the exact location of the house, septic system and well to be at least fifty-five (55) feet from the center line of the road.  If the subdivider deeds to the town, as a donation, the amount of land necessary to bring the road to a fifty-foot right-of-way, the separate plot plans will not be required.

 

 

3.       Sizes.

a.       Residential Lots.  For subdivision purposes, minimum lot sizes for residential lots shall be not less than one (1) acre [forty-three thousand, five hundred sixty (43,560) square feet], containing the 35,000 square feet of contiguous high and dry area.  For the purposes of this Section, a “dwelling unit” is defined as one (1) or more rooms arranged for the use of one (1) or more individuals living together as a single housekeeping unit, with cooking, living, sanitary and sleeping facilities.  Whenever the average slope of thirty percent (30%) or more of any lot exceeds a grade of fifteen percent (15%) minimum land area required by this section shall be increased by fifty percent (50%).   Whenever any part of any leach field will be located within two hundred fifty (250) feet of Little Island Pond, Gumpus Pond, Long Pond, Harris Pond, Beaver Brook, Golden Brook, New Meadow Brook, Little Island Pond (Gage) Brook, Gumpus Pond Brook, Tony’s Brook or Harris Brook, the minimum land areas required above shall be increased by thirty-three (33%).  All calculations used to determine lot sizes to meet the requirements of this section must be submitted as part of the complete subdivision application.

b.       Industrial Lots.     No lot for the use of an industrial building shall be less than two (2) acres in size.

c.       Commercial Lots.No lot for the use of one (1) or more commercial buildings shall be less than sixty thousand (60,000) square feet in size.

d.       Computation.        In computing the minimum lot sizes required by Section XII-B-3(a), (b), & (c) above, the following land areas shall not be counted but shall be shown on the plan giving the total square footage of such non-usable land:

 

1.       Land areas located outside of the geographical boundaries of the Town of Pelham;

2.       Land areas located within any Recreational-Conservation-Agricultural District;

3.       Land areas having wetland soils symbols as defined in  Section A  of Definitions;

4.       Land areas that would be flooded by a one-hundred-year flood, the scope of said one-hundred-year flood to be determined by the United States Department of Housing and Urban Development and the Federal Insurance Administration;

5.       Land areas that are deemed hazardous by the Planning Board.  “Hazardous Land” is defined as land that is of such a character that it cannot be safely used for building purposes because of potential danger to health and safety from flooding, explosion, fire pollution, ledge, landslides, lack of water, unstable soils, soil erosion, inadequate access or other menace.  “Hazardous Land” includes, but shall not be limited to, land areas within the New England Power Company’s high-voltage power line easements and land areas with a slope in excess of twenty-five percent (25%).

6.       Land areas that are or have been the subject of an excavation, as defined by RSA 155-E, I and II, and which have not been restored in accordance with the Pelham Hazardous Pits Ordinance, [Editor’s Note:  See Chapter 208, Excavations.]   RSA 155-E and regulations adopted subsequently by the Board, whether or not such restoration is or was required by the Pelham Hazardous Pits Ordinance or RSA 155-E or the regulations adopted subsequently by the Board.

 

e.       Additional Requirements. In addition to meeting the minimum lot size requirements contained herein, the subdivider shall meet all minimum lot size requirements imposed by the regulations established by the New Hampshire Water Supply and Pollution Control Commission, imposed by the Pelham Zoning Ordinance and imposed by the Pelham Health Ordinance.   No waiver of minimum lot size requirements by the New Hampshire Water Supply and Pollution Control Commission, the Pelham Board of Adjustment or the Pelham Health Officers shall be binding upon the Pelham Planning Board for subdivision purposes.  In appropriate cases, the Planning Board may vote to concur with such a waiver by granting a variation pursuant to Section V of these regulations.

 

4.       Shape.

 

a.       Lots will be shaped to form a residential neighborhood that is attractive to the eye, which takes advantage of natural topography, best preserves environmentally sensitive areas, and contributes to maintaining the rural atmosphere of the Town.  Lots of exactly the same shape are acceptable but sub-dividers are encouraged to use creativity to maximize the value and attractiveness of the neighborhood for future residents and to the town.  If lots are proposed which are all the same shape, the sub-divider must demonstrate to the Planning Board how this configuration benefits the sub-divider, the neighborhood, and the town.  Pie shaped lots and shapes that, in the judgment of the Planning Board, have the potential for creating problems between neighbors are to be avoided.  They will generally not be approved.

 

 

5.       Steep-Sloped Lots.

 

a.       Whenever the average slope of more than twenty-five percent (25%) of a proposed lot exceeds fifteen percent (15%), a separate topographical plan of the lot, drawn to a scale of one (1) inch equals twenty (20) feet or to such other scale as the Board may designate, shall be prepared, and six (6) copies shall be submitted to the Board.   The separate topographical plan shall be based on an on-the-ground topographical survey with at least one (1) elevation point taken for every two thousand (2,000) square feet of land.   The elevation points shall be evenly distributed over the lot and the elevation points, and numbers shall be shown on the plan.    The separate topographical plan shall show existing contours, using two-foot contour lines, the actual location of at least one (1) benchmark, all exposed ledge and all ledge within two (2) feet of the ground surface; and the proposed location of all driveways, buildings, septic systems and wells to be constructed or installed on the lot.   In addition, six (6) copies of the proposed profile of each driveway shall be submitted to the Board.  Whenever, in the opinion of the Board, the topography so requires, the Board may request such additional information as it deems necessary to determine whether a proposed lot may be properly developed.

 

 

 

C.      SIDEWALKS

 

Sidewalks of not less than four (4) feet in width, and conforming to the grades of the street, shall be constructed on one (1) or both sides of streets when, in the opinion of the Board, such sidewalks are necessary.  Sidewalks shall be constructed in all new subdivisions within one (1) mile of a church or school.  If sidewalks are required, specifications are as follows: The sidewalk shall be constructed five (5) feet behind the curb line of the street with a base of eight (8) inches of crushed gravel and having a minimum thickness of two and one-half (2 ½) inches after compression of bituminous concrete applied in two (2) courses.  Handicap ramps shall be provided at street intersections and at the point of termination and constructed to state specifications.

 

D.      WATER SUPPLY

 

a.       No lot in a proposed subdivision shall be approved until it is established to the satisfaction of the Board that the lot can be provided with an adequate economic supply of potable and palatable water.  Where, in the opinion of the Board, the geology or elevation of the land so requires, the Board may require drilling and pumping of test wells before granting subdivision approval.

b.       When each lot is to be supplied by its own individual well, the proposed location of the well shall be shown on the plans by an appropriate symbol.  Individual wells must be located in a minimum of seventy-five (75) feet from any leach field and septic tank.  All wells shall be set back a minimum of forty (40) feet from the edge of the road right-of-way.

c.       When more than one (1) lot is to be supplied by a single well or a group of wells, that is, when a water system is to be utilized to supply the subdivision, plans and specifications showing the site and location of the wells, storage tanks, water mains, fire hydrants, etc. shall be submitted in triplicate to the Board for approval.   Those plans and specifications shall be in conformance with the American Water Works Association’s standards for municipal water systems and meet all applicable Federal and State standards for public water systems.  All water mains shall be made of ductile iron and shall have a minimum inside diameter of eight (8) inches.  Water main sizes and hydrant spacing shall meet the minimum fire flow requirements established by the New Hampshire Board of Fire Underwriters.

 

 

E          NATURAL FEATURES.

 

1.       Where a proposed park, playground, school or other public use shown in the Master Plan is located in whole or in part in a subdivision, the Board may required that dedication or reservation of such area within the subdivision in those cases in which the Board deems such requirement to be reasonable.

2.       Upon consideration of the particular type and size of the subdivision, especially in developments not anticipated in the Master Plan, the Board may require the dedication or reservation of such other areas or sites of a character, extent and location suitable to the needs created by such development for open space, schools, parks and other public facilities.

 

F.         DRAINAGE.

a.       Storm Drains, Culverts, Underdrains & Related Installations.   Storm drains, culverts, underdrains and related installations, including catch basins, gutters, ditches and manholes, shall be installed within the subdivision, as necessary, to permit the unimpeded flow of all natural watercourses; to ensure adequate drainage of all low points, sags in roadway, upstream corners of the roadway at intersections; to control erosion; and to intercept storm water runoff along streets at intervals reasonably related to the extent and grade of the area drained.   Such drainage facilities shall be located in the street right-of-way, where feasible, or in perpetual unobstructed easements of appropriate width.

b.       Drainage Structures and Class IV Reinforced Concrete Pipe.   Drainage structures, culverts or other drainage facilities shall, in every case, be large enough to accommodate potential runoff.  At no time shall the minimum pipe size be less than fifteen (15) inches of Class IV reinforced concrete pipe (RCP).  All RCP shall be laid on a minimum of six (6) inches of crushed stone no smaller than three-fourths (3/4) inch.  Backfill must be gravel or sand.  At no time shall corrugated pipe be used.  Where adjacent property is not subdivided, pipe sizing, grades and location shall be in such a manner as to facilitate the proper extension of the drainage system.

c.       Acceptable Drainage Method.   For normal drainage, peak runoff rates shall be estimated using the acceptable drainage method approved by the Planning Board with a twenty-five year storm frequency.  All culverts shall be designed to ensure that there will be no washout of the road during a fifty-year frequency storm.  Culverts crossing street rights-of-way shall extend from one edge of the right-of-way to the other.

d.       Responsibility for Drainage Downstream.   The subdivider’s engineer shall provide such information as the Board deems necessary to determine the effect of the subdivision on the existing downstream drainage facilities outside of the area of the subdivision.  Where the Board anticipates that the additional runoff incident to the development of the subdivision will overload an existing downstream drainage facility so that there will be damage to private property or an increase in the expenditure of public funds, the Board shall not approve the subdivision until the subdivider makes adequate provisions at the subdivider’s expense for all downstream drainage.  Open drainage ditches shall be properly stabilized.

e.       Catch Basins.   Catch basins will be required on both sides of the roadway on continuous grade at intervals of not more than four hundred (400) feet and shall conform to the Town’s standard details.  The use of catch basins is to accept surface water and channel it into the storm drainage system, therefore each catch basin will be independent of each other and the drain manholes will be used in the storm drainage system.   At the low point on all vertical curves of the street and at all intersections, double grated catch basins will be used.   Storm drains and culverts shall not be less than twelve (12) inches inside diameter.  The subdivider’s engineer shall be responsible in determining if, for the particular system, shorter spacing of catch basins and/or larger pipe sizing is required.  Where ditches are utilized, provision must be made at all driveways to ensure even uninterrupted flow of drainage.  (The catch basin standard details are located in the Appendix).

f.        Curbing.   Curbing is required lining for both sides of all streets where grades are in excess of four percent (4%), and the roadway is to conform to the town’s typical cross section with curb.”

g.       Natural Waterways.   Natural waterways shall be utilized to the fullest extent feasible.

h.       Culvert Cover.   There shall be at least twenty-four (24) inches of cover over culverts crossing roadways, and for culverts over fifteen (15) inches in diameter, the Board may specify additional depth of cover.  All culverts shall have headers of pre-approved design.

i.    Erosion and Sedimentation Control.       A subdivider’s engineer shall provide adequate control of soil erosion and sedimentation in the development of land.  The following provisions shall apply:

B.        Final Inspection.

 

1.       A final inspection may be requested, pursuant to Section X (Performance Guarantee) of these Subdivision Regulations.    This inspection shall be a visual inspection to determine compliance with the approved plans, where a punch list shall be generated to the Planning Board for compliance.   The developer shall have a final as-built plan made showing all utilities, finish grades, bounds, drainage showing location and inverts and all other required documents must have been submitted to the Town at this time.

 

SECTION XVI - RESERVATION STRIPS.

 

A.        No plan which incorporates so-called reservation strips which would prevent further extension of development shall be approved.

 

 

SECTION XVII - COMPREHENSIVE PLAN-PREMATURE DEVELOPMENT. 

 

A.      Comprehensive Plan.       The Pelham Zoning Ordinance, the Pelham Building Code, the Pelham Health Regulations, the Pelham Land Subdivision Regulations, the Pelham Site Development Regulations, the Pelham Capital Improvements Program, the Pelham Master Plan and applicable state statutes and regulations constitute and provide a Comprehensive Plan for the orderly development of the Town of Pelham.

B.      Objectives of Comprehensive Plan.        Among the many objectives of the Comprehensive Plan for the orderly development of the Town of Pelham are the following:

 

1.       The preservation of the rural environment, small town character, open spaces and cultural heritage now attached to the Town;

2.       The development of the town in a reasonable, orderly attractive manner, rather than in a completely haphazard and unattractive manner.

3.       The development of the Town at a rate of growth which will allow the Town to provide adequate police and fire protection; adequate, safe, well-maintained streets and highways; uncrowded, adequately equipped and staffed schools and other public services without overburdening the financial resources of the Town and its residents;

4.       The development of the Town in a manner that will not make residency in the Town financially unattainable to low and moderate-income families;

5.       The development of the Town at a rate of growth that will not outdistance the Town’s ability to adjust to the growth.

 

C.      Findings.   The Pelham Planning Board makes the following findings with respect to the Comprehensive Plan for the orderly development of the Town of Pelham:

 

1.       The Board finds that the premature development of large tracts of land will hinder the Town in its effort to accomplish and fulfill the many objectives of its Comprehensive Plan.

2.       The Board finds that the complete subdivision of large tracts of land within a relatively short time period would endanger or injure the health, safety and prosperity of the Town of Pelham and would necessitate an excessive expenditure of public funds to provide public services;

3.       The Board finds that the complete subdivision of large tracts of land within a relatively short time period would place an unacceptable burden upon the Town’s school system and the financial resources of the residents of Pelham who must support that system;

4.       The Board finds that the complete subdivision of large tracts of land within a relatively short time period would have an adverse impact on the quality of the education being provided by the Pelham School System.

5.       The Board finds that the complete subdivision of large tracts of land within a relatively short time period would have an adverse impact on the Town’s effort to provide adequate police and fire protection and safe, well-maintained streets and highways.

6.       The Board finds that, while there is a need to provide housing for the expanding population of this nation, this need is not best served by the rapid premature growth that results from the complete subdivision of large tracts of land within a relatively short time period.

7.       The Board finds that the complete subdivision of large tracts within a relatively short time period constitutes premature subdivision of land.

 

D.  Authority. New Hampshire Revised Statutes Annotated 647:36II (a)      provides that land subdivision regulations may provide against such scattered premature subdivision of land as would involve danger or injury to health, safety or prosperity by reason or the 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.

 

E.   LIMITATIONS ON THE PREMATURE SUBDIVISION OF LAND.   No separate lot of    land shall be subdivided into more than ten (10) new separate lots of land during any one (1)       calendar year.  Any subdivision of more than ten (10) lots shall be built in phases of not more      than ten (10) lots per year.  For the purposes of this subsection, a separate lot of land is a lot     of land which, on January 1, 1978, was carried on the real estate tax assessment records of the            Town of Pelham as a separate lot of land.

 

F.       LIMITATION OF COMPUTATION OF NO SUBDIVIDER DESIGNATION.   The numerical limitation on the premature subdivision of land imposed by Subsection E above shall apply to the entire original separate lot of land as shown on the January 1, 1978, real estate tax assessment records of the Town of Pelham regardless of how many times the original lot may be subdivided after January 1, 1978.  Therefore, in the absence of a designation made by the subdivider, whenever a lot in excess of ten (10) acres is subdivided, each new lot created will carry with it its proportional share of the lot approvals permitted by Section XII.   Each lot’s proportional share shall be completed by dividing the total acreage of the original lot as of January 1, 1978, into the separate acreage of each new lot.  The resulting number, rounded to the next higher whole number, shall determine the number of additional lots that may be created out of the original January 1, 1978 lot.  For example, if the original lot, which contained sixty (60) acres on January 1, 1978, were to be subdivided in July of 1978 into two (2) lots, one forty (40) acres and the other twenty (20) acres, in 1979 the forty-acre lot could be subdivided into seven (7) lots and the twenty-acre lot could be subdivided into four (4) lots.

 

G.      LIMITATION OF COMPUTATION IF DESIGNATED BY SUBDIVIDER.   A subdivider, at the time subdivision approval is sought, may designate what proportion of the premature subdivision limitation number shall be conveyed with each new lot.   The designated proportion, stated in terms of a percentage of each new lot, shall be clearly shown on the original and each copy of the subdivision plan.   The stated percentages shall also be recorded in the minutes of the Board.


 

20.    High Intensity Soil Survey - This regulation applies to subdivisions on which an on-site septic tank and leach field system is to be used for sewage disposal and where wetland identification is required.  In addition to any other town and state sewage disposal requirements for local subdivision plan reviews or wetland zoning compliance, the following regulations shall apply:

1)       A base map consisting of an on-the-ground survey shall be prepared using a scale of one (1) inch equals fifty (50) feet, showing all dimensions to the nearest hundredth of a foot, showing a North arrow and having the error or closure not more than one (1) part in eight thousand (8,000).

2)       Ground control shall be marked, by the applicant, both on the site and on the plat map(s).  The ground control shall consist of numbered flags, stakes, walls, trees, or other easily identifiable points on the property.  These points shall be well distributed throughout the site at a density of not less than four (4) points per acres.  The numbered points must be identified, by number, on the plat plan.  The purpose of this requirement is to provide easy identification for all parties required or interested in examining the site.

3)       The location shall be shown of all major site features, such as existing stone walls, fences, buildings, large trees, wooded areas, cleared areas, rock outcropping and ledges, swamps, brooks, streams and other bodies of water.

4)       High-intensity soil survey (HISS) maps are to be provided for all subdivisions.  Applicants may request the board to waive this requirement upon recommendation of the Hillsborough County Conservation District.  Applicants request waiver of the Board, the Board requests recommendation of HCCD and the Board acts upon HCCD recommendation.

5)       The HISS maps shall be prepared by a licensed soils scientist in the State of New Hampshire.

6)       Eight (8) copies of the HISS maps shall be provided to the Board.  In addition to the soils information provided by the survey, the map shall have on it the following:

a)       The signature of the qualified soils scientist;

b)      Any qualifying notes made by the soils scientist.

7)         If a soils classification provided on the HISS map is in dispute, the Planning Board may request an evaluation of the soils designations by the HCDD.

8)       A leach field area of four thousand (4,000) square feet or an area two (2) times the required leach field area, whichever is greater, shall be designated and reserved on each lot.

9)       The designated leach field area must be left open and is not to be used for the siting of any incompatible purpose, including but not limited to a driveway or parking area, or structures of any type.  Driveways or parking areas may be located over the designated leach field area when chambered systems are to be used. 

21.    Site Specific Soil Mapping Standards - The Board informally requests of applicants, if they so choose, to also delineate soil information required by the Site Specific Soil Mapping Standards.  The Board wishes to incorporate these standards by the year 2002, and in the transition would informally request this information.  However, this information is not required by these subdivision regulations as it has not yet been formally adopted.
