I. 
Requirements prior to any road construction. Immediately prior to any clearing for road construction, the location of the pavement within the road dedication and the extent of clearing shall be approved by the Board during a site visit. Under no circumstances shall the clearing for road construction exceed what is necessary to construct the road surface, shoulders, drainage ditches (if required) and cut and fill slopes. If the Board authorizes the movement of the road's center line off the center line of the road dedication to save specific trees, the trees to be saved shall be prominently banded so that they may be observed during road construction.
J. 
Driveway stub requirement. Prior to placing the binder course, a driveway stub built to roadway specifications not less than 20 feet in length (with drainage structures, if required, installed to facilitate ditch drainage) shall be installed on each lot.
A. 
Grading and preparation for pavement. The roadway shall be graded and prepared as follows:
(1) 
Clearing and grubbing (Section 101 of the Standard Specifications). The paved area and shoulders of each street or way shall be cleared and grubbed to remove all trees not intended for preservation, stumps, brush, roots, rocks or boulders and other unsuitable material which may exist upon the surface.
(2) 
Excavation (Section 120 of the Standard Specifications). The entire area of the roadway shall be excavated to remove all materials encountered within the paved area and shoulders down to the true surface of the subgrade, or to suitable material in the areas where unsuitable materials exist, in preparation for foundations of roadway, sidewalks, driveways and berms. Materials obtained from the excavation may be used in fills as needed if they are sampled and tested by an independent testing laboratory acceptable to the Board or its agent and, in the opinion of the Board or its agent, the material satisfies the requirements of Section 150 of the Standard Specifications. Necessary laboratory testing to determine the suitability of the excavated soil shall be arranged for and paid for by the applicant.
(3) 
Embankment (Section 150 of the Standard Specifications). When in the opinion of the Board or its agent, suitable material is not available within the limits of the roadway location to form the subgrade or subbase, the developer shall obtain suitable additional material from other sources in accordance with this section, and as may be approved by the Board or its agent. A certificate of compliance along with information on the source of the material being used shall be submitted to the Board or its agent for approval prior to use.
(4) 
Grading (Section 170 of the Standard Specifications). The subgrade surface, 16 1/2 inches below the finished surface grade in minor streets and 18 inches below the finished surface grade in major streets, shall be prepared true to the lines, grades and cross sections given and compacted with a vibratory roller to achieve 95% compaction. The prepared subgrade shall then be proof rolled with a combined weight of 70,000 pounds to determine that the subgrade does not contain weak or unsuitable soil. All soft or spongy material below the subgrade surface shall be removed to a depth determined by the Board or its agent, and the space thus made shall be filled with suitable material conforming to Section M 1.02.0. of the Standard Specifications. Material used shall contain no stones over six inches in their largest diameter or any other material detrimental to the subgrade.
(5)

(3) 
Ditches. Ditches shall be constructed adjacent to the roadway whenever the center-line profile grade of the roadway is six inches or more lower than the adjacent topography or when required to intercept or redirect runoff when construction of the roadway results in runoff being directed onto the pavement. Ditches shall be constructed in accordance with the approved plan.
E. 
Areas disturbed by construction.
(1) 
Loam and suitable vegetative cover approved by the Board shall be placed on all side slopes and other areas disturbed by construction in accordance with § 300-32 unless other types of vegetative or inorganic cover are approved for use or are determined by the Board to be necessary for erosion control. (See § 300-32.)
(2) 
Erosion control plan. Before approval of a subdivision, the developer shall prepare and submit for approval of the Board or its agent an erosion control plan covering all phases of construction for the area in which he intends to perform work. This area shall be specified and may include the portion of work within the right-of-way or may include all or part of the lots depending on the extent of work and location of wetlands. The following factors shall be considered in such a program:
(a) 
Construction activities shall be phased so that construction can be completed rapidly and large areas are not left bare and exposed for long periods.
(b) 
Grading shall be kept at a minimum. Where possible, existing trees and vegetation shall be protected and retained. Only undesirable trees shall be removed.
(c) 
Drainage shall be maintained by the contractor during construction. Runoff shall be controlled and conveyed into storm sewers or other outlets so it will not erode the land or cause off-site damage.

A. 
Materials and installation methods.
(1) 
Utilities shall be installed in accordance with the approved plan. No utility mains shall be installed under the pavement except at intersections, and stubs crossing the street shall be installed prior to paving. Utility main installation after placement of pavement shall be approved by the Board and shall conform to Figure 17.[1] Unless otherwise specified, all materials and installation methods shall conform to the standards of the town.
[1]
Editor's Note: Figure 17 is included at the end of these regulations.
(2) 
All underground utilities and other structures located within the right-of-way shall be installed in the right-of-way before completion of the roadway subgrade and before placing of the subbase, pavement and sidewalk. If the pavement is broken for underground installation of structures or utilities, pavement repair shall be in conformance with Figure 17.
(3) 
Excavation for structures (Section 140 of the Standard Specifications). Excavation for structures, including foundations for drains, sewers, gas and water pipes, walls and other structures shall be made to the depth indicated on the definitive plan or established by the Planning Board or its agent as appropriate.

When provided, they shall be constructed in accordance with the approved plans and the current standards of the American Association of State Highway and Transportation Officials (AASHTO) Roadside Design Guide. Construction details of all fences, rails and walls shall be shown on the definitive plan for the subdivision. Whenever possible, such fences, rails and walls shall be of a rustic nature to blend with the character of the town.
B. 
Stone wall appearance.
(1) 
Stone walls in New England and in Boxford are a proud hallmark of our heritage and are a fundamental quality of the charm and special nature of Boxford.
(2) 
Stone walls shall be simple and modest. They are usually three feet in height and give the viewer the impression that they are almost naturally part of the landscape.
(3) 
Boxford stone walls are part of a rural farming community. They are not to be suggestive of a formal massive estate entrance constructed in such a manner so that they look as if they are finished works with uniform dimensions and surfaces and smooth lines.
(4) 
Stone walls shall be constructed (or at least appear so) by carefully piling the stones without visible mortar. Here again the element of simplicity is present, in fact properly piling the stone requires careful planning, especially if the wall is to have the necessary amount of structural integrity to withstand the pressure of plowed snow. Boxford stone walls shall not have bronze or metallic plaques embedded in the surface.
(5) 
The ends of a stone wall should be as simple and natural as the wall itself. Importantly, at openings for driveways or roads, the stone wall should not be perfectly curved to parallel the road flair, which would be characteristic of a suburban development.
Retaining walls when required shall be constructed of field stone and mortar and shall be finished with a concrete cap to prevent deterioration. See Figure No. 15.[1]
[1]

D. 
The placement and accurate location of these monuments and markers shall be certified by a registered land surveyor and properly located on the as-built acceptance plans.
A. 
From the time of rough grading until such time as each street is accepted by the town as a public way, the sign posts at the intersection of such street with any other street shall have affixed thereto a sign designating such street as a private way.
B. 
Street signs for each intersecting street shall be installed at each intersection to conform to those used the Boxford Department of Public Works.
C. 
No street sign, temporary or permanent, shall be installed showing a name other than the one approved by the Board.
D. 
Subdivision signs may be temporarily posted for a period not to exceed two years from the sale of the first lot within that subdivision. After that period, the sign must removed. The Inspector of Buildings will police such action.
A. 
Where required by the Board, street and pedestrian lighting shall be installed to conform to the type and style in general use in the Town of Boxford unless otherwise specified by the Board, and no lighting shall be installed except as approved by the Board. It shall be located on a suitable post, which may be a concrete, aluminum or square section of creosote-treated wood having a height of 25 feet or more as approved by the Board.
