B. 
Prior to ordering materials or starting any construction, the subdivider together with his contractor and engineer (if applicable) shall arrange for a meeting with the Engineering Division and the City Planner. At this meeting, the rules for conducting construction operations in the subdivision and on city streets will be outlined and discussed. Notices to be given, methods and materials to be employed, how utility connections are to be made, fees required and other operational matters will be discussed.
A. 
The entire area of each street or way shall be cleared of all stumps, brush, roots, boulders, like material and all trees not intended for preservation.
B. 
All loam, clay, peat or other yielding material shall be removed beneath all street layouts to a depth specified by the Town Engineer and shall be replaced with a granular material acceptable to the Town Engineer.
C. 
Whenever it is necessary to install fill to bring a roadway to subgrade, said fill shall be of a granular material satisfactory to the Town Engineer. All fill shall be placed in eight-inch layers compacted to not less than 95% of the maximum dry density, as specified in Section 150.62 of the Commonwealth of Massachusetts Department of Highways Standard Specifications for Highways and Bridges (MHD Specifications), as amended.
[Amended 12-5-1996]
D. 
Wherever the borings indicate a groundwater within four feet of the proposed roadway surface or wherever the soil particle size indicates the possibility of a capillary rise of water in the subgrade soil, subdrains shall be installed under both shoulders of the roadway. The design and depth of the subdrain shall meet with the approval of the Town Engineer.
E. 
Wherever rock, in the opinion of the Town Engineer, is encountered, it shall be excavated to a depth of four feet below the subgrade of the roadway for the full width of the street layout. The excavated rock shall be replaced with a granular material satisfactory to the Town Engineer.

(1) 
The material used for the gravel subbase shall be gravel approved by the City Engineer, which meets the Commonwealth of Massachusetts Department of Highways Standard Specifications for Highways and Bridges (MHD Specifications), as amended, Material Specification M 1.03.0 Type b (three-inch maximum size) and conforms to construction methods stipulated in Section 401.60, except that all courses shall be laid in depths not exceeding four inches compacted depth.
(2) 
The maximum size aggregate for subbase courses shall not exceed four inches. The cost of any soil tests needed to determine the suitability of a material for use as a subbase shall be borne by the developer.
(3) 
The gravel shall be spread and compacted in layers not exceeding six inches in depth compacted measurement. The gravel shall be compacted to the density specified in § 401 of the MHD Specifications.
I. 
Gravel base. The material used for gravel base shall be dense-graded crushed stone approved by the City Engineer, which meets MHD Specification M 201.7 for material and is placed in conformance with Section 402 for construction.

J. 
Pavement. The material used for the roadway finish course shall be Class I bituminous concrete Type I-1 applied in two courses. The material and work shall conform to § 460 of the MHD Specifications and shall meet with the approval of the Town Engineer. The installation of all subsurface utilities within the roadway shall be completed before placement of the first (binder) course. Where there is concern over possible settlement, the City Engineer may require one winter season to elapse between utility installation and top course pavement installation. In no event shall the interval between placement of binder course and top course of pavement exceed two years. The construction of bituminous concrete pavement shall terminate on November 15 and shall not be resumed prior to April 1 unless specifically allowed, in writing, by the Town Engineer. No paving shall be done when the air temperature in the shade is 40° F. or less nor where the material on which the pavement is to be placed contains frost. A tack coat of bitumen at the rate of 0.05 to 0.10 gallon per square yard shall be applied to the base course of pavement, all as determined be the City Engineer. Material and placement shall be as approved. The tack coat shall be only applied to the extent that it can be covered with the surface course within one day.
[Amended 12-5-1996]
K. 
Roadway pavement design. Using soil information obtained as required in § 159-7C(8), a pavement design shall be prepared utilizing California bearing ratio values or equivalent values obtained for the subgrade. This will normally be required in clay, loam, peat or silt subgrade materials or as otherwise required by the Town Engineer. The design shall consider and employ, as needed, increased thickness of the gravel subbase, use of geotextile fabric and/or plastic grids, use of subdrains and other measures necessary. (See also Subsections C and E.) This design shall be included in the definitive plans submitted for review by the Planning Board. See Table 5.1[1] for minimum thickness of the gravel base, subbase and pavement.

To prevent wind and water erosion, the following measures must be employed on all sites:
A. 
Regions of the site must be developed in separate increments so that the disturbed area is kept to a minimum. At no time is the entire area to be disturbed.
B. 
Natural vegetation shall be retained and protected whenever possible.
C. 
All disturbed area shall be stabilized with a temporary vegetative cover if to be left exposed for greater than one month, with the exception of roadways which are to be treated with appropriate measures at the end of each workday.

All excavations for pipe, etc., across streets and to dwellings shall be properly protected and lighted at proper times, according to recommendations of the Department of Public Works and the Chief of Police. These excavations shall be properly backfilled and well-compacted as soon after installation of pipe, etc., as is possible.
A. 
In any area outside the road right-of-way and building site (house plus 15 feet outside walls and leach field area), no tree over eight inches in diameter measured five feet above the ground shall be removed without the consent of the Tree Warden or his agent. Due regard shall be made for life expectancy and health of the vegetation and the final proposed grading. The developer shall notify the Tree Warden at least one week prior to any clearing of the site. No evergreen tree or shrub shall be removed without consent of the Tree Warden or his agent. Limits of work may be delineated on the definitive plan, in which case no work shall be performed, including clearing, outside those limits, but work within may proceed without further consent.

Before final inspection, the total area shall be cleared of debris, both natural and construction materials generated by the construction.
All proposed monuments shown on the definitive plan shall be installed and their installation shall be certified by the developer's engineer or surveyor. Monuments shall be of stone or cast concrete, four inches square and three feet long, set flush with the finished grade. Three-fourths-inch to one-inch steel pipes or gun barrels three feet long may be used at lot corners. Where street monuments and lot corners occupy the same point, stone or concrete monuments shall be used.
Upon completion of any subdivision or any street therein and prior to the final release of a bond or covenant, the developer shall submit to the Board a final plan of each street layout, including lot frontage, bounds and pins which have been set and ties to intersecting street layouts. This plan shall be used as a street acceptance plan and shall be drawn in accordance with standards set by the Town Engineer. The plan shall be prepared by a registered professional land surveyor and shall be suitable for recording in the Hampden County Registry of Deeds. Accompanying this plan, the developer shall supply the Board with a document releasing the Town from any damages which he may incur by the acceptance of the street by the Town.
