A. 
The Applicant shall install all of the improvements itemized herein unless waived in writing by the Board. All work done in accordance with these specifications shall be subject to the inspection of the Planning Board and the Planning Board's Agent.
B. 
No aforementioned bond or covenant shall be released until full approval in writing of all work done is received by the Planning Board from its Agent. Such approval shall be in a form mutually satisfactory to the Planning Board and the Board's Agent and shall, at a minimum, cover those matters set forth in § 117-46 below.
C. 
Any removal of earth from the site shall be in conformance with the Town of Newbury Earth Removal By-Law, Chapter 60. No loam, gravel or other earth materials of any kind shall be removed from its original position in any subdivision until such time as the performance guarantee has been submitted, accepted and approved by the Board. No removal of loam from the development shall be made until a six-inch thickness of compacted loam shall have been placed throughout the entire area of all lots and on the planting strips along the roadway. Only such areas designated as roadways, driveways, building sites and areas requiring filling may be excavated for construction purposes. Should it come to the Planning Board's attention that soil has been removed from the site, approval of the Subdivision will be revoked until remedial measures are taken and the final result approved by the Planning Board.
Unless otherwise specified herein, all construction shall be performed in accordance with the most recently amended "Standard Specifications for Highways and Bridges" of the Massachusetts Department of Transportation.
A. 
Clearing and grubbing: Existing trees within the area of the right-of-way may be selected for preservation of aesthetic or other values by the Planning Board provided they shall be over six (6) inches in diameter at 4' 0" above the ground and shall be located at least five feet from the edge of the finished roadway pavement. No trees shall be removed until said selection is made. Such trees to be preserved shall be protected from bruises and other abuses continuously throughout the construction of the subdivision in a manner satisfactory to the Planning Board. The developer shall give the Board twenty-one days' notice to allow the Board to select the trees to be saved. The entire area of each right-of-way shall then be cleared of all stumps, brush, roots, boulders, and like material and all trees not intended for preservation.
B. 
Excavation and subgrade preparation: All topsoil and other yielding material shall be removed for the full length and width of the paved roadway and from under the sidewalk location when sidewalks are required regardless of whether or not the finished grade is above the existing grade. With the roadway at the subgrade level, all pipes and underground services shall be laid. Backfill will be with clean, granular material, and shall be compacted in six-inch lifts with equipment satisfactory to the Planning Board's Agent. All roadway fills will be constructed of earth free of stumps, brush, trash, organic material or other deleterious materials. Fill material shall be placed in six-inch maximum lifts. The moisture content shall be kept at optimum by means of water trucks (if dry) or blading the material (if wet). The road fills shall be compacted with rollers satisfactory to the Planning Board's Agent to 95% maximum density in conformance with ASTM Standard D1557. Written evidence of satisfactory test results shall be given to the Planning Board by the Applicant. Tests shall be performed by a licensed testing lab, and shall be arranged and paid for by the Applicant.
C. 
Gravel base and grading: After the roadway has been carefully graded to the required subgrade elevation, at least 12 inches of base gravel shall be spread and rolled with a roller of sufficient weight to achieve 95% compaction of gravel per ASTM Standard D1557. Satisfactory compaction levels shall be confirmed by compaction tests; such tests shall be arranged and paid for by the Applicant, and results forwarded to the Board and its Agent, which tests shall be by such method and by such testing company as shall be satisfactory to the Board. The gravel shall be placed in two six-inch lifts, and rolled with a vibratory roller of at least 12 tons static weight. Gravel shall be in conformity with the gradation shown in the definition "Gravel" in Article I. When spread on the road and rolled, it shall form a stable foundation. All banks and curves must be established before the bottom course of wearing surface can be applied. The roadway crown shall have a minimum of one-quarter inch per foot of pitch.
Note: The Planning Board reserves the right to require a thickness of base course greater than 12 inches if subgrade conditions require it.
D. 
Pavement or wearing surface: The wearing surfaces shall consist of a three inch thickness, after compaction, of Class 1, Type I-1 plant mixed bituminous concrete composed of materials and prepared in conformity with the "Standard Specifications for Highways and Bridges" of the Massachusetts Department of Transportation (latest edition). It shall be spread and rolled in two courses, a two inch thick binder course and a one inch thick top course in conformity with the Specifications aforementioned. The first course shall be swept clean prior to the placement of the second course, and a tack coat must be applied to insure proper bonding of the two courses. A leveling course may be required prior to the installation of the second course. Any patches to the wearing surface shall consist of three inch thickness, after compaction, and shall be applied in the same manner as the wearing surfaces, as set forth above.
All required utilities exclusive of transformers shall be placed underground at the time of initial construction. Required utilities may include water, sewer, storm drainage (where allowed), electricity, gas, wiring for street lights, fire alarm systems, and telephone, cable, fiber optic and other communications lines. All construction will be in accordance with the latest edition of the Massachusetts Department of Transportation "Standard Specifications for Highways and Bridges" or the specifications of the applicable utility company, unless otherwise specified by the Board. All utilities which are placed above ground, i.e. transformers, shall be placed outside the right of way so as not to interfere with the placement of the streets, roadways and/or sidewalks and the Applicant shall provide easements on lots within the subdivision for this purpose.
A. 
Surface water drainage: Design and construction shall be in conformance with "Rules and Regulations, Town of Newbury Stormwater Management, Illicit Discharge and Erosion Control." Drainage systems relying on gutters, catch basins, and underground piping will be allowed only where country drainage is not feasible. The "Rules and Regulations, Town of Newbury Stormwater Management, Illicit Discharge and Erosion Control" shall apply to all subdivisions, whether or not they are in the MS4 area, and whether or not the subdivision is subject to G.L. c. 131.
(1) 
Pipes, culverts, and drains: Pipe for the construction of culverts and drains shall be reinforced concrete except where such culverts or drains pass under a roadway or driveway, in which case they shall be ASTMC76 Class V reinforced concrete. All pipe shall be not less than 12 inches in diameter. Pipe joints shall be carefully made so that the spigot is tightly butted to the seat of the bell and the spacing between the spigot is uniformly proportioned. The joints shall be filled with mortar in all cases. All utility trenches shall be filled with bank run gravel or clean excavated in-place materials carefully compacted in six-inch lifts, to 95% maximum density. All drains shall be laid to uniform slope and shall be carefully bedded so that the pipe is supported throughout its entire length with compacted earth.
(2) 
Shoulder or so-called French drains shall be located wherever the final road excavated surface intersects the seasonal high ground water table. Such drains shall be at least three feet in depth and two feet in width and otherwise sufficient to interrupt such flow of water and divert it from flowing under such proposed street or roadway.
(3) 
Catch basins: Catch basins shall have a minimum thirty-inch sump. All catch basins shall discharge into manholes. The distance between two catch basins shall not exceed 300 feet. The Planning Board may require a lesser distance if deemed advisable by the Board because of unusual local conditions; catch basins shall be installed at all breaks in grade (low points).
B. 
Water Mains: Where applicable, water pipes and related equipment, such as hydrants and main shut-off valves, shall be constructed to serve all lots on each street in accordance with the current specifications of the Newburyport Water Commission, the Old Town Water District, or the Byfield Water District. Hydrants shall be provided and placed at intervals of not more than 500 feet along each street. Backfill should be bank-run gravel or clean granular in place material compacted in six-inch lifts to 95% maximum density.
(1) 
Except where necessary to cross a street, all water pipes and related equipment shall be installed on one side of the street. Where only one sidewalk is required by the Planning Board, the water pipes and related equipment shall be placed on the other side of the street. All water pipes and related equipment shall be placed away from the paved roadway and any sidewalk so as to minimize the amount of roadway cutting or sidewalk cutting required in the future for repairs by the applicable water supply agency.
(2) 
Water piping shall be class 52 cement-lined ductile iron, placed on a minimum six-inch (6") deep compacted sand bedding course. The first twelve inches (12") backfill above the pipe shall be compacted sand. All backfill shall be to 95% maximum density. Water piping shall be placed at least 10 feet (10') clear horizontally away from sewer lines. Where water lines must cross sewer lines, the water line must be placed eighteen inches (18") clear above the top of the sewer pipe.
(3) 
Water mains shall be pressure-tested and sewer and drainage lines lamped prior to the placement of the base course gravel.
C. 
Sewer Mains for centralized Sewage Treatment Systems: Gravity mains shall be a minimum of eight inches (8") SDR 35 PVC. Force mains shall be schedule 40 PVC, sized to provide a minimum self-cleaning velocity. All sewer pipes shall be bedded and backfilled similar to water pipe as specified above. Manholes shall be placed at a maximum of four hundred foot intervals (400') and at every change in pipe slope and direction. Sewer mains shall be checked for alignment by "lamping." A pipe out of vertical alignment shall be removed and reinstalled. A small horizontal misalignment may be tolerated at the Planning Board's sole discretion. Sewer mains shall be air tested at 4 PSIG pressure.
Unless the Planning Board determines that pedestrian movement is otherwise provided for, sidewalks will be required along the street. Sidewalks shall have a width of not less than five feet, a gravel base of eight inches, and a two inch thick bituminous pavement. Sidewalks shall be constructed between the roadway and the right-of-way line, as close to the latter as practicable, and generally parallel with the roadway. Minor streets shall be provided with sidewalks on one side; secondary and principal streets shall be provided with sidewalks on both sides. The inclusion of bicycle paths is encouraged. Pedestrian access other than by routes parallel to roadways may be permitted, with proper easements.
A. 
Permanent monuments shall be granite, four feet in length and four inches square, and shall be set at locations shown on the Definitive Plan. A 3/8 inch drill hole shall be placed in the top to indicate the point. The tops shall be set four-inches above the final grades of the adjoining ground. All permanent monuments shall be properly placed, backfilled and tamped with a good binding gravel and shall be adequately protected if placed before all construction is completed. Placement and location of monuments shall be done by a Professional Land Surveyor and shall be shown on the Record Drawings.
B. 
Permanent monuments shall be installed at all street intersections and at all points of change in curvature of streets (at 1,000-foot intervals maximum on tangents). Iron pipes shall be installed at the front two corners of individual lots within the subdivision and at other points where, in the opinion of the Board, permanent monuments are necessary. No permanent monuments shall be installed until all construction which would destroy or disturb the monuments is completed.
Curb and gutter drainage will be allowed only where country drainage is not feasible. Where required, sloped granite curbing shall be installed as edging on paved roadways, at roadway intersection roundings, and in other specific locations as determined by the Board, with inlet curbs, and transition pieces at catch basins. Sloped granite curbing shall be backed up with concrete.
A. 
The Applicant shall furnish and erect street signs at the locations shown on the Definitive Subdivision Plan to designate the name of each street in a subdivision and each intersecting street, prior to construction of any house on the street. The signs shall conform to the street sign standard used by the Town of Newbury and shall be installed under the direction of the Director of Public Works. The Planning Board shall approve the name of any new subdivision street.
B. 
Streets within a subdivision that have not yet been accepted by the Town as public ways shall have conspicuously posted, by and at the expense of the Applicant, signs at intersections, acceptable to the Director of Public Works, stating "Private Way." The latter sign shall be a separate sign that is attached before the signage that sets forth the name of the way, suitable for easy removal when and if the way is accepted by the Town as a public way.
The area outside the pavement shall be sloped no steeper than three horizontal to one vertical (3:1) until it intersects finish grade of abutting lots, except as may be required for sidewalks, all as shown on the typical street cross-section. All such slopes shall be loamed and seeded, as shall all grass swales. Flatter or steeper slopes may be required by the Board depending upon soil conditions. Steeper slopes may be required by the Planning Board depending upon soil conditions, especially in areas of ledge.
Retaining walls or other slope stabilization construction may be required to eliminate any slopes steeper than three horizontal to one vertical other than stable rock slopes. The design, type and location of any wall or other construction shall conform to all requirements of the Massachusetts State Building Code (Latest Edition) and shall be shown in detail on the Definitive Plan Drawings.
All grass swales, grass strips and other unpaved areas within the street right-of-way shall be covered with at least six inches of loam (depth after compaction) before seeding.
The Applicant shall make every effort to preserve the existing trees on the right-of-way and on the lots to be sold. No tree in excess of six (6) inches in diameter at 4' 0" above the ground shall be removed within a subdivision without the approval of the Planning Board. Filling and cutting of roadways shall be done in such a manner as to preserve the trees whenever possible. No fill shall be placed against the trunk of any tree to be retained.
It is recognized that it may not be practical, in most cases, to save trees within the right of way, except in cul-de-sacs. It is anticipated that when the centerline of the roadway has been staked, the Planning Board and the Subdivider's representative will walk the right-of-way and mutually agree which trees are to be saved. This may result in modification to the alignment of the roadway.
The Board shall require planting of trees when, in its opinion, existing trees are insufficient to provide an attractive setting. Trees shall be provided by the Applicant in accordance with the Definitive Plan, which shall specify the number of required trees and note the size, location, and a type of stock compatible with site conditions for each planting. At any time prior to the release of the performance guarantee pursuant to § 117-18L hereof, the Planning Board may also require that additional trees be planted when, in its opinion, such additional trees are necessary to provide an attractive setting. The Board shall approve the size, location, and type of stock for each planting.
In no case shall trees of any type with less than a three-inch caliper be planted.
