A. 
It is the intent to set forth design and construction standards consistent with the statements of intent in Article I (and other provisions) of this chapter, with the requirements of the Protective Bylaw, with the objectives of the Master Plan, and with standards which are used for roads constructed by the expenditure of public funds; to provide for siting of streets and ways so as to provide convenient access to uses on individual lots and convenient access for the repair, maintenance, revision, or storage of utilities, water, fuel, communications, and disposal of waste; and to provide for design and construction of roadways that minimizes the need for future maintenance or reconstruction, that provides a roadway base that will not move or frost heave, that inhibits erosion, and which provides for both surface and subsurface drainage adequate to accommodate the impact of twenty-five-year and one-hundred-year storms.
B. 
The subdivision design and construction shall meet or exceed the minimum standards contained herein. The subdivider shall be responsible for complying with these standards even if the plans indicate otherwise, unless a specific variance therefrom has been expressly authorized in writing by the Planning Board. Construction standards, except as specifically modified in this chapter, shall be in accordance with the Massachusetts Department of Public Works Standard Specifications for Highways, Bridges and Waterways (1967), hereafter abbreviated "SSHBW." Specific references to SSHBW do not exclude other applicable provisions. The term "engineer" in SSHBW shall be interpreted as the Board or its designated inspector.
C. 
This article and Article V, Mini-Subdivision, of this chapter also contain design criteria based on publications of the American Association of State Highway Officials (hereafter abbreviated "AASHO"), Washington, D.C., in particular "A Policy on the Geometric Design of Rural Highways" (1965) and "A Geometric Design Guide for Local Roads and Streets, Part I, Rural" (1971 Revision of the 1970 Edition). The latter is abbreviated hereafter "AASHO DG."
The subdivision in general shall conform to the Master Plan, if any, adopted in whole or in part by the Planning Board except as the same purposes may, in the judgment of the Board, be served better by modifying the Master Plan for the general area of the subdivision.
A. 
Preservation of existing assets. The subdivider shall make every reasonable effort to preserve natural and other features, such as large trees, watercourses, scenic points, historic spots, stone walls and other aspects of rural, historic, and regional character, and similar assets. The Planning Board encourages property owners and subdividers to make use of conservation grants or easements, most particularly in wet areas, and of common land held by a qualified homeowners' association.[1]
[1]
Editor's Note: Throughout this chapter, the term "automatic-membership homes association" was changed to "qualified homeowners' association" at the request of the Town.
B. 
Parks and open space. The subdivision plan shall show a park or parks of suitable character and location for playground, recreation, or open space uses (SCL § 81U). Such areas shall be of reasonable size. Unless otherwise specifically authorized by the Planning Board, the total area so reserved shall not be less than 10% of the gross area of the subdivision outside any W District, and each such area shall have at least the frontage and access of a Type 2 lot. The Board shall, by appropriate endorsement on the plan, require that no building may be erected on such lands for a period of three years without its approval. Such areas shall be available to the Town or may be held indefinitely as open common land by a qualified homeowners' association acceptable to the Planning Board and including all property owners in the subdivision, provided the Town through the Conservation Commission is granted such rights as are sufficient to assure the permanence of the open character of the land.
A. 
General design and location.
(1) 
Streets shall be designed so that, in the judgment of the Planning Board, they shall provide safe vehicular travel and safe and reasonable access to the lots which they serve, so that driveways from the street to usable areas of lots can be installed completely within the boundaries of each lot in conformity with the bylaws of Harvard without undue hardship and without requiring blasting or easements onto other properties, and so that such streets will provide a reasonable maximum of attractiveness, livability, and amenity of the subdivision.
(2) 
Streets shall also be located so as to permit each lot to have its water supply and sewage disposal system, including the entire leaching field, located on the main portion of the lot, thereby providing ready, safe, and convenient access to all parts of the system so as to facilitate and assure its periodic cleaning and servicing and its repair, expansion, or reconstruction by the owner when necessary. However, the Planning Board may waive compliance with the preceding sentence where the Board specifically finds it in the public interest to approve a plan with such modifications, conditions, limitations, and requirements it considers necessary to provide ready, safe, and convenient access to all parts of the sewage disposal system, including the entire leaching field, and to facilitate and assure such periodic cleaning and servicing, repair, expansion, and reconstruction. (See § 130-6 of this chapter.)
B. 
Access.
(1) 
Provision suitable in the opinion of the Planning Board shall be made for the projection of streets and access to other streets and adjoining property. All lots shall be designed to conform to the Protective Bylaw both before and after the construction of future projections or access streets. Reserve strips prohibiting access to streets or adjoining property will not be permitted except where the Board deems it in the public interest.
(2) 
Access to facilities on parcels which are not part of building lots shall be over rights-of-way along common boundaries between lots, which shall be improved by access drives which the Planning Board judges adequate for the purpose served, but at least constructed to the standards of a gravel-surface, single-lane mini-subdivision drive.
(3) 
Utilities, pipelines, communication and emergency warning cables, waterlines, sewer pipes, and similar amenities which must serve or go past lots not in the same ownership shall be carried along the street or over rights-of-way along common boundaries between lots; they shall not be carried in rights-of-way cross lots. Such rights-of-way shall be improved along the entire length as in Subsection B(2) preceding and/or shall be directly accessible from a drive so improved running alongside it. Where such amenities are to be installed to serve lots in the subdivision, the rights-of-way shall be shown on the plot plan and site plan, and the improvements to, and amenities within, such rights-of-way shall be completed as part of the improvements for which completion security is posted.
C. 
Intersections. Streets shall intersect at right angles unless, in the judgment of the Planning Board, this is impracticable; in no case shall the angle be less than 60°. (See also Subsection D, Geometric design, below.)
D. 
Geometric design. It is the intent that all streets and intersections within the subdivision, and outside of it, shall be so designed and constructed or reconstructed as to provide for the safe and rapid flow of traffic while preserving the environmental integrity and historic values of the neighborhoods through which they pass.
(1) 
Except as otherwise specifically provided in this chapter, street and roadway design, layout and construction shall provide for:
(a) 
Street width > 25 feet on each side of the (roadway) center line.
(b) 
Street flare at intersections > that of Figure 1.[1]
[1]
Editor's Note: Figure 1 is included at the end of this chapter.
(c) 
Center-line radius (of curvature) > 200 feet (> 80 feet in turnarounds).
(d) 
Sight distance (outside turnarounds) as given in the accompanying Table of Clear Lines of Sight.

(2) 
The Planning Board may require greater standards for principal streets.
E. 
Dead-end streets. Dead-end streets shall be provided with a turnaround (Figure 2)[2] providing for one-way traffic in a counterclockwise direction. All lots shall be designed to conform to the Protective Bylaw both before and after any extension. Such streets shall be < 500 feet in roadway center-line length to the beginning of the turnaround except:
(1) 
As a section of an expected development of land in common ownership with the locus wherein, in the judgment of the Planning Board, the way will become continuous, with the order of development chosen to minimize the time and probability of discontinuity; or
(2) 
Where, in the judgment of the Board, a greater length is necessitated by topography or other local conditions.
[2]
Editor's Note: Figure 2 is included at the end of this chapter.
F. 
Shoulders and embankments. (See also § 240-25B, Shoulders and guardrails.)
(1) 
Shoulders. Shoulders shall extend six feet from the roadway, sloping up at 1:6 (vertical:horizontal) for the first two feet and 1:12 thereafter.
(2) 
Embankments.
(a) 
Banks joining shoulders to natural grades shall have slopes no steeper than 1:3, except for short stretches approved by the Planning Board on which the slope may be up to 2:3 in suitable soil and up to 4:3 in sound rock, provided that:
[1] 
Soil slopes between 1:3 and 1:2 shall be stabilized by at least six inches of wood chips, and suitable retaining walls and/or riprap is used to provide safety and maintainability on steeper slopes; and
[2] 
Suitable easements are provided for slope access and maintenance; and
[3] 
The Planning Board endorses on the plan conditions restricting the number and type of lots that may use such stretches as access frontage if it deems such restrictions appropriate (SCL § 81R).
(b) 
Embankments having more than 10 feet of elevation change shall be terraced at roughly equal vertical intervals, not to exceed eight feet, with provisions adequate in the judgment of the Planning Board to interrupt, divert and (if necessary to counter erosion) to drain the downward flow of runoff, the breakout of subsurface flow, and erosion products.
(3) 
Guardrails. Guardrails shall be provided in the outer one foot of shoulder where the bank slope down from the shoulder is greater than 1:4 and otherwise as required by the Board.
G. 
Utilities.
(1) 
Utility lines, including telephone, electric, and any fire alarm lines, shall be underground unless, in the judgment of the Planning Board, it is impracticable for a particular interval because of conditions, such as extended ledge, especially affecting such interval. Mains shall be located in the shoulder outside the gravel base. Any lighting standards shall be in the outer one foot of the shoulder. Easements shall be provided as needed and shall be > 20 feet wide. Telephone service shall be provided from the 772 or 456 exchange or from new or successor exchanges serving mainly, or only, telephones in Harvard.
(2) 
Any pipes which are installed to carry drinking water, or sewage, or runoff or subdrainage from leaching fields, shall be separate from the fire-fighting water supply and the storm drainage system. Such pipes shall be of materials and size adequate in the judgment of the Planning Board for their purposes and shall be buried below the frost line.
H. 
Drainage. (See also § 130-25C, Drainage.) It is the intent to require a surface and subsurface drainage system that will keep the base and subgrade of the roadway dry to prevent frost heaving and to have storm drains that will cope with major storms without flooding and without leaving ice or other residues on roadways and which are designed so that the volume and rate of runoff and/or erosion are not greater after, or during, the installation of the subdivision than previously.
(1) 
Capacity. Drainage design shall be adequate, in the judgment of the Planning Board, for handling the watershed peak discharge of a twenty-five-year storm (one-hundred-year storm for bridges and culverts along natural watercourses) during and after the completion of all improvements within the subdivision, and within potential additional subdivisions that may lie hydraulically uphill, and shall include control of erosion, flooding, and ponding of runoff, as well as accepting effluence from street subdrains and other water table modification or control within the subdivision. (Town driveway connection regulations[3] prohibit the discharge of runoff and erosion products into the roadway; drainage design shall include means satisfactory to the Planning Board of dealing with such potential problems from individual lots, including restrictions limiting construction methods used in installing driveways.) The Board may require a more intense design storm where it deems more protection is needed or for areas not economically susceptible to future relief. Design watershed discharge shall be at least that of the rational formula Q = ACi (Seelye, Data Book for Civil Engineers, Third Edition, 1957, Wiley), where:
Q =
Watershed peak discharge
A =
Watershed area
C =
Coefficient of runoff
i =
Rainfall intensity based on time of concentration
[3]
Editor's Note: See Ch. 140, Art. II, Driveway construction and connection permits.
(2) 
Connections and easements. Connection shall be provided to appropriate existing drainage systems, and proper drains and easements shall be continued at such size and grade as will allow for appropriate projection of the drainage system. Adequate drainage rights in the subdivision and on neighboring property shall be procured. Streams and other watercourses shall have easements conforming substantially to the course and in no case less than 20 feet wide or extending less than 10 feet from the edge of any stream.
(3) 
Storm sewers.
(a) 
No surface water shall be carried across the roadway, or along the surface of the street for more than 300 feet. Basins shall be provided on each side of the street at low points in the roadway, near the corners of the roadway at intersecting streets, including intersections with existing streets, and in any case at intervals < 300 feet. Manholes shall be provided at changes of vertical or horizontal alignment or size of drain pipe, and in any case at intervals < 300 feet. Gutters shall be provided for grades > 3%, within 20 feet of a basin, and otherwise as required by the Board. Leaching basins or swales without exit will not be considered adequate disposal of water.
(b) 
Pipes, manholes, catch basins, junctions, and other components used in constructing the drainage system shall be of a consistent and compatible manufacture throughout the subdivision, so as to require a minimal subsequent stockpile of spare parts for repairs and revisions.
I. 
Footpaths. Footpaths shall be provided. Footpath width shall be > four feet. The path shall be located > two feet from the edge of any embankment, > one foot outside the shoulder, and have horizontal clearance > 2.5 feet on each side of the center line, with grades and curvatures suitable for pedestrian and bicycle use and for maintenance. The course of such a path shall be adjusted to preserve stone walls, suitable trees, and other features. The Board may permit the roadway center line to be located two feet off the street center line where a footpath is being provided on only one side of a minor street. The path may leave the street; an easement > 10 feet in width on either side of the path center line shall be provided. Where such a footpath crosses a roadway, there shall be visible guides of paving stone or other means specified by the Planning Board to show the crossing. (See also § 130-25D, Footpaths.)
J. 
Traffic guides. Curbing and traffic islands or other traffic guides may be required by the Planning Board. Turnarounds shall be marked for one-way traffic.
K. 
Trees. Suitable existing trees < 12 feet high outside the shoulders shall be preserved. Where suitable trees do not exist at intervals < 50 feet on each side of the street they shall be provided. (See also § 130-25E, Trees.)
L. 
Street signs. Street signs shall be provided at each intersection in the outer one foot of the shoulder. (See also § 130-25G, Street signs.)
M. 
Bounds. Permanent bounds shall be provided on each side of the street at intersections and changes of direction and curvature. (See also § 130-24B, Lot bounds required, and § 130-25F, Bounds.)
A. 
Fire ponds or cisterns required. Fire ponds or cisterns of equivalent capacity shall be provided for fire protection, so that every part of every street in the subdivision is within 3,600 hose feet, along streets, of a satisfactory fire pond or cistern. Where, in the judgment of the Planning Board, the terrain or the uses to which the buildings will be put so require, the Board may require a more intense design. Fire ponds and cisterns shall be independent of one another in drawdown, so that the complete emptying of any one in use results in no more than a ten-percent drawdown of any other storage supply of water usable for fire fighting. Suitable access and easements to fire ponds and cisterns and their sources of recharge water shall be provided. If desired, such areas may be deeded to the Town or may be held by a qualified homeowners' association as for parks above.
B. 
Lot bounds required. Lot bounds of at least semipermanent type shall be provided sufficient that lot boundaries may be readily ascertained by a builder or lot owner. (See also §§ 130-23M and 130-25F.)
C. 
Pedestrianways other than streetside footpaths. Pedestrianways or other access may be required by the Planning Board to provide suitable circulation or access to schools, playgrounds, parks, conservation areas, shopping, or other facilities. Off-street rights-of-way shall be > 20 feet wide.
(See also § 130-23, Street design, above.)
A. 
Roadway subgrade, base and surface.
(1) 
The entire width of the roadway and shoulder areas shall have been cleared and grubbed (SSHBW § 101, Clearing and Grubbing). All existing material shall be excavated to at least subgrade level of > 14 1/2 inches below finished grade (SSHBW § 120, Excavation) over the entire width of the gravel base, all soft or spongy material removed, and the subgrade prepared (SSHBW § 150, Embankment, and § 170, Subgrade). Subsurface drainage shall be used in shoulders or embankments to collect seepage or springs that may be opened in construction and generally to control groundwater level at the roadway; construction cloth shall be used where necessary to prevent the infiltration of sediment into the rock packing surrounding such subdrains. Drains, culverts, basins, manholes, and other underground utilities in and adjacent to the subgrade shall be installed before the finished subgrade is prepared.
(2) 
The basic gravel base shall extend > two feet beyond the roadway on each side, with an additional two feet on the inside of a roadway of center-line radius < 150 feet.
(3) 
The roadway surface shall have a crown of four inches and be paved (SSHBW § 460, Class I Bituminous Concrete Pavement, Type I-1) > 2 1/2 inches thick over a gravel base (SSHBW, § 405, Gravel Base Course) > 12 inches thick. Paving shall consist of a binder course > 1 1/2 inches compacted measure followed by a finish course > one inch compacted measure. The gravel base shall be spread in layers < four inches, compacted measure, of gravel per SSHBW M 1.03.0 (Type b) (maximum size of stone, three inches largest dimension) and shall be penetrated with bituminous liquid asphalt, once the roadway is prepared to accept it, as follows: Bitumen M.C. 70 shall be applied at a temperature of 250° F. to 275° F. at the rate of 1/2 gallon per square yard, 24 feet wide, for the full length of the roadway. The roadway shall then be barricaded and not used for 24 to 48 hours. Application shall take place only when the roadway, weather, and temperature are, in the opinion of the Subdivision Inspector, favorable for a satisfactory result. Sand will not be used to absorb surplus bitumen, unless the Subdivision Inspector so directs.
B. 
Shoulders and guardrails.
(1) 
Shoulders (SSHBW § 445, Shoulders) over the gravel base shall be brought to finished grade with gravel; shoulders elsewhere, banks, and other areas disturbed by construction shall have at least four inches of loam, rolled measure, and be seeded or provided with other permanent ground cover planting approved by the Planning Board.
(2) 
Guardrails shall be of the steel-beam type, galvanized (SSHBW § 601, Highway Guard). Post spacing shall be < 11 1/2 feet. Alternatively, the Board may permit the use of suitable wooden posts, set < eight feet on centers with steel cables and fittings in accordance with New Hampshire Standard Specifications for Road and Bridge Construction (1974), Section 6.06, Guard Rail, including Subsections 2.1, 2.2 and 2.7. A transition section, including cable anchors where cables are used, shall be provided sloping upward from near ground level and funneling inward for approaching traffic. (See also § 130-23F above.)
C. 
Drainage. Drainage (SSHBW § 230, Culverts, Storm Drains and Sewer Pipes) pipes for surface water shall be > 12 inches in diameter and shall have > two feet of cover for reinforced concrete pipe and > three feet otherwise. Such pipes shall be of reinforced concrete or ACCM (asphalt-coated corrugated metal). Basins, manholes and inlets shall be in accordance with SSHBW § 201, Basins, Manholes and Inlets; however, the outside of block structures shall be plastered. (See also § 130-23H above.)
D. 
Footpaths. Footpaths shall be constructed in accordance with SSHBW § 701, Sidewalks. The gravel foundation uses the same gravel [SSHBW M 1.03.0 (Type b)] as the gravel base for the roadway. The path surface shall be either:
(1) 
Bituminous concrete per SSHBW, except that a surface layer of stone screenings (SSHBW M 2.03.0) shall be spread over the paving surface prior to the final rolling of the finish course; or
(2) 
A course of stone screenings, > one inch thick, compacted measure, evenly spread, wet and compacted. (See also § 130-23I above.)
E. 
Trees. Trees shall be of varying species approved by the Planning Board. Trees shall be planted in at least 1/2 cubic yard of loam and shall be properly wrapped and guyed to ensure survival. (See also § 130-23K above.)
F. 
Bounds. Bounds shall be embedded > 3 1/2 feet below, and extend 1/2 foot above, finished grade (SSHBW § 710, Bounds). At grade in sound ledge, bounds shall be marked by exposing fresh sound rock with a horizontal surface at least six inches square and using a drill hole 1/2 inch in diameter and one inch to two inches deep. (See also §§ 130-23M and 130-24B.)
G. 
Street signs. Street signs shall be similar to those used by the Town and be approved by the Highway Superintendent. Each intersecting street shall be identified by a separate sign on the post, and dead-end streets shall be so identified prominently. When applicable, a separate sign(s) reading "Not an Accepted Way of the Town of Harvard" shall also be provided on the same post. (See also § 130-23L above.)
H. 
Seasonal construction prohibition. In general, no construction shall be done during unfavorable seasonal or weather conditions. In particular, paving is not permitted below 40° F. or between November 15 and April 1, and embankment (with other than rock) and subgrade preparation are not permitted in frozen material or between December 1 and April 1 (SSHBW §§ 150, 170 and 460).
I. 
Cleanup. Upon completion of the work, the subdivider shall remove from the street and adjoining property all rubbish, surplus material, and temporary structures and leave the area in a neat, orderly condition, free from holes or other unusual hazards.
It is the intent to provide fire ponds or cisterns of equivalent capacity that will meet the fifty-year-drought guidelines of organizations which rate local fire protection facilities for static bodies of water for fire protection and, except where more stringent standards or greater capacity is called for by this chapter, the guidelines of the National Fire Protection Association (NFPA) and the United States Soil Conservation Service (USSCS), in particular, the following: NFPA Standard 1231 (Suburban and Rural Water Supplies 1975), Chapter 4 and Table 13-5-1 of Appendix B; NFPA Standard 1 (National Fire Prevention Code 1975), Section 3-1.1.10 (Required Access for Fire Apparatus); United States Department of Agriculture Handbook No. 387 (Ponds for Water Supply and Recreation); and USSCS Information Sheets MA16 (October 1976, Ponds for Fire Protection) and RTSC-NE-ENG 606 (Non-Pressure Fire Hydrant). Fire ponds and their access shall conform to the following:
A. 
Construction and drawdown.
(1) 
A satisfactory fire pond shall have a normal available drawdown of at least 60,000 gallons over a two-hour period at any time of year (30,000 gallons over a two-hour period during the fifty-year drought). Such a fire pond shall have a storage capacity of at least 60,000 gallons (8,000 cubic feet) between two feet below mean annual low water and 1.5 feet above the pond bottom. The Board may require greater capacity in accordance with NFPA 1231, Chapter 4 (1975 Edition) for major buildings, or for industrial, commercial, institutional or multiple-residence use, or on the basis of the size and type of buildings that it expects to be constructed. The pond shall generally conform to USSCS MA16. It shall be at least eight feet deep and have a flat bottom with an area at least 25% of the nominal surface area and side-slope grades not exceeding 1:3 in soil (except as may be required for direct suction hose access). Side slopes shall be stabilized with riprap if they exhibit weepage or movement during construction. The pond shall be located if possible where it receives maximum recharge and cleaning action from natural flow and be connected with a nearby stream if necessary. Pond depth and recharge shall be such that no less than half the above capacities and drawdown rate will be available throughout the year of the fifty-year drought.
(2) 
If the fire pond is not located on, or adjacent to, a flowing stream, the applicant shall furnish, at his expense, proof that the pond or cistern when built will be able to furnish 30,000 gallons at a drawdown of 250 gallons per minute by means of the accesses provided on any day of the year during the fifty-year drought.
(3) 
If there is no suitable location or recharge for a fire pond, the applicant shall provide a cistern of equivalent capacity and access and the means for keeping it full when not in use. Such cisterns shall not be used for drinking water and shall be equipped with means to prevent unauthorized emptying.
B. 
Access.
(1) 
The fire pond shall have an off-the-roadway access to a dry hydrant and suction hose insertion where an American Association of State Highway Officials (AASHO) SU30 single-unit truck may be parked and turned around without interfering with the flow of traffic. A simple roadside turnout that can be kept clear by routine snowplowing during winter is preferred over more complicated arrangements.
(2) 
The entire length of any driveway between the roadway and the access to a fire pond shall be constructed for use as a fire lane (NFPA 1, Section 3-1.1.10) to a width of at least 20 feet and shall have:
(a) 
No overhanging branches to a height of 15 feet; and
(b) 
All-weather base and all-weather finish to sustain use by 16,000 pounds per axle, with base and subbase meeting subdivision roadway standards; and
(c) 
Drainage of the finished driveway and its base, using culverts at least 12 inches in diameter ACCM construction; and
(d) 
Sustained grades not to exceed 8% (NFPA Standard 1231, Appendix B).
(3) 
A fire lane to a fire pond, or a driveway used as such a fire lane, shall be constructed for two-way traffic in accordance with Harvard Protective Bylaw § 125-39B, generally to the full twenty-foot width of the fire lane.
C. 
Dry hydrant. Access to the pond and its water shall include a dry hydrant designed and installed with six-inch pipe in accordance with USSCS MA16 and RTSC-NE-ENG-606, except that the hydrant itself shall be of the type normally used on street water mains so that it can be backflushed by the connection of an additional hose. The inlet shall be at the deepest part of the pond and shall be supported 1 1/2 feet above it and be equipped with a trash screen, approved by the Board, of at least eight inches in diameter and 18 inches in length.
D. 
Fence. The fire pond shall be surrounded by a so-called nonclimable fence that meets the requirements of the Harvard Swimming Pool Bylaw[1] but through which all parts of the pond are visible. It shall have a gate near the dry hydrant which can be used for suction hose and maintenance access.
[1]
Editor's Note: The Swimming Pool Bylaw was excluded from the Code at the direction of the Town.
E. 
Restrictions and easements.
(1) 
The entire access from the roadway to the fire pond shall be designated a fire lane for a distance of 10 feet on either side of the center-line fire lane of any access driveway that may be provided. This fire lane shall not be used for parking or obstructed in any other way.
(2) 
If the access to the fire pond lies wholly or partly along a shared driveway, the provision for driveway maintenance and snow removal shall include the following:
(a) 
Prohibition of parking or obstruction along any parts of the fire lane or fire pond access; and
(b) 
Provision for snow removal and maintenance of the ramp and turnaround area at the fire pond.
(3) 
There shall be an easement to the Town of Harvard to make use of the access and to use and maintain the fire pond and fire lane.
(4) 
The Planning Board may require as a condition endorsed on the definitive plan (SCL § 81R) that no buildings be erected, and/or as a condition on the covenant for release of lots, that no lots be released until the fire pond(s) is actually built. For other than single- or two-family dwelling uses, the Planning Board may also endorse on the plan limitations on the volume of any building to be erected, on the basis of the actual supply of fire-fighting water and the quantities and pumping rates for a given size and class of building as set forth in NFPA 1231, Chapter 4 (1975 Edition).
F. 
Approvals. Judgments of adequacy, conformity, or approval referred to in the documents cited in Subsections A through E above, or in this chapter, will be by the Planning Board, which will consult appropriate firesafety officials when the Board deems such consultation necessary or desirable.
After completion of all improvements, the subdivider shall be responsible for maintenance to these standards until the street has been accepted by the Town or acceptance has been refused on its merits at an Annual Town Meeting.
