The Planning Board, in consultation with the Conservation Commission and Board of Health, shall study the preliminary plan and may conduct field visits. For an open space subdivision, the Board shall formally determine which land should be preserved and where development may be located. The Planning Board shall make written findings supporting this determination. The Planning Board may deny any application that does not include sufficient information to make such a decision or that does not preserve land that the Planning Board determines should be preserved from development as a result of its findings.

In the case of a proposed preliminary plan that deviates from the requirements of the Open Space Subdivision Bylaw, § 240-4.5, such plan shall only be considered in conjunction with a special permit application for such deviation, which may be submitted simultaneously with the preliminary plan. If the Planning Board determines that the land with the greatest conservation value cannot be protected except by the use of an open space subdivision plan, the Planning Board shall deny the special permit for the deviation. The applicant may then submit a plan that complies with the requirements for an open space design subdivision.

After submission of a preliminary plan and within the period set forth in MGL c. 41, § 81S, both the Planning Board and the Board of Health shall notify the applicant by certified mail and Town Clerk in writing that the plan has been approved, or that the plan has been approved with modifications suggested by either the Board or agreed to by the applicant, or that the plan has been disapproved. In the case of disapproval, each Board shall state in detail its reasons therefor. Approval of a preliminary plan shall not constitute approval of the proposed subdivision.

The term "definitive plan" as used in these rules and regulations shall mean a plan of a subdivision within the meaning of the Subdivision Control Law12 prepared by a professional engineer, land surveyor or landscape architect registered in Massachusetts.

The Planning Board encourages thorough analysis and resolution of design issues in the preapplication conference and/or preliminary plan stage prior to submission of the definitive plan. A definitive plan for a conventional subdivision will not be considered unless the Planning Board has conditionally approved a special permit for such a subdivision layout deviation, based on information, analysis and other requirements specified in §§ 380-2.8C and 380-2.9F of these Rules and Regulations. At the time of the filing of the definitive plan, it should be accurate, correct and complete on the day of submission. In addition, all features of the definitive plan should be consistent with the design standards described in Article IV. Any deficiencies and inaccuracies shall be grounds for denial of the definitive plan.

It is recommended that a licensed design professional be responsible for the coordination of the elements of the definitive plan, prepared by other professionals.

The definitive plan shall be clearly and legibly drawn in india ink or laser plotted on four mil double-sided mylar or three mil single-sided mylar to a scale of one inch equals 40 feet on sheets measuring 24 inches by 36 inches and shall comply with the recording requirements of the Register of Deeds or of the filing requirements of the Land Court, in the case of registered land. If multiple sheets are used, they shall be accompanied by an index sheet of the same dimensions drawn to an appropriately reduced scale. All required plans and documents required shall also be submitted as electronic files in pdf format.

Editor's Note: See MGL c. 41, §§ 81K to 81GG.

Give written notice to the Town Clerk, by delivery or by registered mail, postage prepaid, that the applicant has submitted such definitive plan to the Planning Board, together with a copy of Form C and a copy of the definitive plan as submitted. Such notice shall describe the land to which the plan relates sufficiently for identification, and shall state the date when such plan was submitted and the name and address of the owner of such land. A definitive plan shall not be considered to have been submitted until the applicant has filed with the Town Clerk a notice stating the date of submittal. If the notice is given by delivery, the Town Clerk shall give a written receipt or a dated stamp of receipt on a copy of Application Form C.

Such plan shall be considered submitted, unless within 21 days of such delivery the Board determines that the application is incomplete because it does not contain the information required in Subsections C, D, E, F (if applicable) and G of these regulations or the proper procedure was not followed. If the application is considered incomplete, the Planning Board shall notify the applicant and the Town Clerk in writing.

Editor's Note: See Schedule C, included as an attachment to this chapter.

The applicant shall be responsible for maintaining, in a healthy condition, all new trees and shrubs planted within the right-of-way of the subdivision streets for a minimum period of one year after planting, and until the street is accepted at Town Meeting. If the location and/or species of the plants is changed from the approved landscape plan by direction of the Tree Warden, the Planning Board or their representative, the new information shall be submitted in the form of a plan to the Planning Board upon completion of the planting. After one season, trees that are dead, damaged or not likely to survive in a healthy state shall be replaced in kind and maintained for at least one additional year.

If, at any time, the construction of the subdivision is not in compliance with the approved plans, or any approved change order, the certificate, and/or the covenant, the Board may order that work on the construction of the subdivision be stopped and request that the Building Inspector defer the issuance of any additional building permits or certificates of occupancy until the noncomplying construction is corrected and brought into compliance. If the Board issues a stop-work order, the Board, or its designees may also require that additional surety be provided to allow for the correction of the noncomplying construction; or suspend or rescind the release of any, or all, lots which have not already been conveyed to a homeowner by filing a notice of such suspension or rescission in the Registry of Deeds.

Method One: performance bond. A performance bond of the applicant running to the Town of Sherborn secured by surety (Form H) or by money or negotiable securities deposited with the Town Treasurer (Form I or Form J) in such amount as the Board shall determine to be sufficient to cover the cost of completing the required improvements, or such portion thereof not secured by covenant under Subsection O(2). Such bond shall be conditioned upon full and satisfactory completion of all such improvements within such time as the Board shall determine, but in no event more than two years from the date of the Board's endorsement of its approval of the definitive plan.

The proposed subdivision design, in particular the placement of housing and infrastructure in relation to wetland resources, will be evaluated based on the groundwater impact assessment analyses (see § 380-2.10F). This assessment will include a hydrogeological evaluation undertaken in accordance with BOH regulations for an environmental health impact report or an equivalent, preapproved evaluation approach, as well as technical evidence that the proposed designs will avoid adverse cumulative impacts to groundwater and wetland resources.

Pollution of groundwater during and after construction shall be prevented by control devices, including provisions for contaminant removal employing detention basins, subsurface drains or perforated risers, oil and grit separator catch basins, and other appropriate devices.

Measures to restrict nutrient loading in down-gradient groundwater to a maximum of five milligrams per liter (mgl) nitrate-nitrogen.

Measures shall be taken to restrict projected nutrient and contaminant levels (resulting from septic effluent subdivision-wide) in groundwater reaching sensitive receptors to a maximum of five milligrams per liter (mgl) nitrate-nitrogen (prior to the application of any nitrogen-reducing technologies).

For septic systems with a design capacity of 2,000 gallons per day or greater and for subdivisions with aggregate septic design capacity of 5,000 gallons per day or greater, the Planning Board will support determinations of the Board of Health and/or Conservation Commission to require monitoring wells at selected sensitive receptors (e.g., drinking water wells, potential sources of drinking water, wetland resources, property lines) with periodic testing (at least once every three years) to detect nutrient and contaminant loadings from subdivision septic systems.

Measures shall be taken to control erosion and sedimentation, as specified in an erosion and sedimentation control plan to be submitted with the definitive plan, and the use of construction site best management practices (BMPs). The erosion and sedimentation control plan should emphasize phased construction, temporary and permanent ground cover, and sedimentation control devices.

All streets and driveways in the subdivision shall be designed so that, in the opinion of the Planning Board, they will provide safe vehicular and pedestrian travel and an attractive street layout to obtain the maximum safety and amenity for future residents of the subdivision and the Town. Ways should run along rather than across a slope to the extent possible.

The proposed streets shall conform in location, so far as practicable, to any existing plans of the Planning Board and, where required by the Planning Board, to the existing street system and include only a minimum number of intersections with streets classified as major arterials.

If deemed appropriate for the site and consistent with the goals of the Sherborn Master Plan, the Planning Board may require that provision be made for the future projection of pedestrian walkways or trails, bicycle paths or streets to, or for access to, adjoining property, whether or not subdivided.

No subdivision shall be approved unless the streets therein connect to, and are accessible from, a public way in which the applicant has the necessary access rights.

Reserve strips prohibiting access to streets or adjoining property shall not be permitted, except where the Board finds them to be in the public interest.

Driveway cuts into streets shall be prohibited until the Planning Board finds that the location, width, length, line of sight, proximity to other driveways and streets, grade and elevation will provide adequate provisions for the public safety.

Existing streets that will be used to access the proposed subdivision shall be of a pavement width and condition adequate for the projected traffic. The Board may require the applicant to fund or conduct off-site improvements if the existing streets are not adequate.

Subdivision streets shall be continuous and of uniform width.

The minimum center-line radii of curved streets shall be 150 feet with greater radii on arterial streets.

A tangent at least 150 feet in length shall separate all reverse curves except where the center line radius of one curve is 500 feet or more.

Street lines at intersections shall be rounded or cut back to provide for a curb radius of not less than 30 feet.

The minimum width of street rights of way shall be 60 feet. The street pavement shall be 22 feet or as approved by the Planning Board based on specific conditions of the site or proposed subdivision. Where a subdivision street intersects an existing street, the minimum subdivision street right of way (ROW) line shall follow a thirty-foot radius drawn between the subdivision street ROW line and the existing street ROW line. The curved, widened subdivision street ROW lines at such intersections shall be entirely within the subdivision property line.

The minimum center-line grade for any street shall not be less than .5%.

The maximum center line grade for streets shall not be more than 8%.

Where changes in grade exceed 1%, vertical curves as required by the Board shall be provided. The length of vertical curve shall be designed to provide a minimum sight distance of 200 feet to an object 4.5 feet above the roadway surface from an eye height of three feet six inches. The sight distance shall be shown on the proposed street profiles.

Where a grade is 5% or greater within 150 feet of the intersection of street right-of-way lines, a relatively level area at least 75 feet long, with a maximum grade of 3%, shall be provided.

Wherever feasible, shade trees 12 inches in diameter or larger shall not be removed from within street rights-of-way, unless approved by the Planning Board.

Where the distance between twelve-inch-plus-diameter trees is such that the roadway is not shaded, the Planning Board may select existing healthy trees of lesser diameter to be retained and protected during construction.

The Planning Board may require that street trees not less than six feet in height and with caliper of at least two and one-half inches shall be planted at varying distances along both sides of every street and spaced on average not more than 40 feet on center.

Roadside rights-of-way shall be graded and planted to maximize retention of road runoff and groundwater recharge.

Curbs shall not be continuous but shall be designed to allow road runoff to drain to roadside plantings and/or swales.

Street trees, shrubs and plant materials shall be selected from an approved list supplied by the Tree Warden.

A continuous healthy growth for all planted trees, shrubs, plants and seeded areas shall be maintained for one year from the date of completion of all work on the street or until the street is accepted by the Town of Sherborn, whichever is later.

Editor's Note: Schedule A is included as an attachment to this chapter.

Driveways shall be at least 10 feet wide, but no more than 20 feet wide, and have a curb return at the street of three feet in radius.

Where no curbs exist, the driveway flare should have a three-foot radius.

Unless otherwise allowed by the Planning Board, driveway cuts shall be permitted only at the street where the frontage requirement has been met.

Shared, or common, driveways serving two dwellings shall be allowed by right. Common driveways serving three or more dwelling units are permitted with a special permit from the Planning Board.

Driveway cuts shall not be permitted within 100 feet of the sideline of intersecting streets or railroad crossings.

No more than one driveway cut shall be permitted per lot unless allowed by the Planning Board.

Any proposed street which connects only with a dead-end street shall be deemed to be an extension of the dead-end street.

Dead-end streets and their extensions, if allowed, shall not exceed 600 feet in length, measured from the center line of the nearest through street with which it intersects to the center line of the circle or ellipse.

Dead-end streets shall be provided with a turnaround [see Subsection G(6) below] at the closed end.

If the Planning Board determines that future extension of a dead-end street to an adjacent property is in the best long-term interest of the Town, the definitive plan shall show the right-of-way lines of each dead-end street projected through the turnaround to the subdivision property line. In this case, street easements in the segments of a turnaround lying outside of such projected lines (including sufficient land beyond the pavement for snow storage or other street maintenance needs) shall be temporary and shall terminate pursuant to MGL c. 41, § 81M, when the street is extended beyond the turnaround. The land between such right-of-way lines between the edge of the paved turnaround and the subdivision property line shall be designated as a separate parcel and shall be conveyed to the Town of Sherborn along with the constructed portion of the street right-of-way at the time of street acceptance. The purpose of the parcel shall be designated on the plan as future street right-of-way.

An applicant who extends a dead-end street at a later date shall remove the pavement, relocate any sidewalks, extend any driveway entrance and properly grade, loam and seed the areas included within the temporary easements. All such work shall be deemed to be a part of the required improvements of the connecting subdivision.

If, by reason of topography or other physical characteristics of land within or adjoining the subdivision, or by reason of the present use or development of the adjoining land, the Board is of the opinion that a particular dead-end street will not be extended beyond the turnaround, the Board may require that the outside right-of-way line of the turnaround be laid out with a radius of 60 feet. A paved circle with a radius of 45 feet and a circular landscaped island having a radius of 22 feet less than the designed radius of the turnaround shall be provided at the center of the turnaround. The circumference of such island shall coincide with the inside edge of the circular paved street.

The center-line profile grade of a turnaround from its beginning to its terminus shall not exceed 3% unless otherwise approved by the Board.

Drainage runoff plans, prepared at an adequate scale to show the full extent of both existing and proposed contributing watershed areas, including existing and proposed contours at two-foot intervals, and existing and proposed drainage systems (shown schematically) with tributary areas to each inlet.

Backup calculations shall reference all sources of information, supporting data and assumptions used.

Drainage design computations shall be based on currently accepted methods (including but not necessarily limited to the Rational, NRCS TR-55, NRCS TR-20 methods), as appropriate for the size, characteristics, and complexity of the existing/proposed drainage system.

Rainfall rates shall be the National Oceanic and Atmospheric Administration (NOAA) Atlas 14, as amended, the Northeast Regional Climate Center (NRCC) "Atlas of Precipitation Extremes for the Northeastern United States and Southeastern Canada," or another currently accepted industry standard that anticipates increased rainfall rates due to the impacts of climate change, as approved by the Planning Board. The specified "design storm" shall be defined as a twenty-four-hour storm using one of the preceding rainfall distribution calculations.

A twenty-five-year storm frequency shall be used for street drainage components and cross culverts.

The proposed drainage system shall be shown to allow on-site recharge equal to or greater than the amount of recharge that existed prior to the development.

In no case shall a drainage line of less than 12 inches in diameter be used.

All drains shall be sloped to provide for a minimum velocity of 2 1/2 feet per second at design flow for self-cleaning purposes. The maximum culvert design velocity shall be 10 feet per second (flowing full).

Where it appears that any street may be extended to connect with an existing or proposed street on land adjoining the subdivision, the Board may require that provision be made for extension of the drainage system to a point at or near the subdivision property line.

Waiver required. The incorporation of retention/detention systems into the proposed drainage improvement program of the definitive plan shall require a waiver by the Board, which may be granted only after the applicant has exhausted all other studies of means of accommodating stormwater runoff by natural drainage strategies. The Board may require that an outside consultant be hired to confirm these studies at the applicant's expense (see Administration article of these Rules).

All drains and related systems shall be protected from erosion and siltation at all times. Prior to construction, all disturbed soils shall be temporarily stabilized, and after construction, all disturbed soils shall be immediately and permanently stabilized.

Any damage to these drainage systems, prior to acceptance by the Town, shall be repaired in a manner satisfactory to the Planning Board and the DPW Director, the full cost of which shall be borne by the applicant.

Easements shall be continuous from lot to lot and street to street, and their layout shall create as few irregularities as possible.

Center lines of easements shall follow lot lines so far as practicable and shall not be less than 20 feet in width.

Easements, or fee strips for pedestrian ways or footpaths, at least 20 feet in width will normally be required to provide convenient circulation and access to parks, schools, playgrounds and conservation areas.

Bridle path easements at least 20 feet in width may be required to connect with conservation areas, open spaces and existing trails.

Existing bridle paths and trails traversing the subdivision shall be preserved with as little relocation as practicable.

In cases where the Planning Board determines that a conventional subdivision design will fulfill the conservation goals of Zoning Bylaw § 240-4.5 better than an open space subdivision design, and a special permit application and preliminary plan for a conventional subdivision is submitted, the applicant is encouraged to set aside green belt sections within the conventional subdivision, consisting of wooded or other scenic areas to be preserved by mutual covenants and traversed by reciprocal trail easements for the benefit of each lot in the subdivision and to provide connections to trails on adjoining lands.

The applicant may grant to the Town or to any private, nonprofit corporation devoted to conservation purposes a conservation restriction or wildlife corridor over any portion of the subdivision in accordance with the procedure prescribed by MGL c. 184, §§ 31 and 32.

Before approval of a definitive conventional subdivision plan, the Planning Board may also require the plan to show a park or parks suitably located for playground or recreation purposes or for providing light and air for the residents of the subdivision. The Board may, by appropriate endorsement on the plan, require that such park or parks may not be converted to building lots without approval of the Board.

No stripping of topsoil shall be permitted in a reserved area. If required by the Board, the land shall be graded as necessary for surface drainage and left in a suitable condition for the intended use.

A sidewalk may be constructed on one side of some or all subdivision streets, or on frontage of existing public ways, if deemed necessary for the safety and conveninece of pedestrians and cyclists, and to facilitate nonvehicular travel within the subdivision.

Paved sidewalks and crosswalks will conform to ADA standards.

Unpaved paths and connections between existing trails or bridle paths may be laid out along subdivision streets within the street right of way instead of, or in addition to, the sidewalk.

Sidewalks and trails will be laid out to optimize connections to surrounding neighborhoods, Town center, and other amenities such as recreational trails and open space.

Sidewalks shall be set back not less than six feet from the edge of the paved street but may be reduced to as little as three feet if a meandering sidewalk is proposed with a minimum of six feet in the area of street trees.

Open areas between the sidewalk and street shall be landscaped with swales and/or plantings for retention and absorption of street runoff and recharge of groundwater resources.

Sidewalks need not be parallel to the street and shall be laid out along a curvilinear course within the right-of-way with a minimum disturbance of the natural terrain. Sidewalks shall be laid out and constructed so as to preserve trees having a caliper of three inches or more, rock outcroppings, stone walls and other attractive features of the terrain. Prior to the start of clearing and grubbing, the applicant shall walk the proposed street locations with the Planning Board agent or a member or members of the Board and mark all trees to be preserved within the street rights-of-way.

Sidewalks shall be four feet in width, unless the Board shall specify a greater width.

Sidewalks shall be paved with bituminous concrete placed on a compacted foundation of gravel as detailed in Schedule A, Typical Section, Subdivision Street.

Sidewalks shall fully comply with the Massachusetts Architectural Access Board requirements, including handicapped access ramps at appropriate locations, as stated in 521 CMR 21.00 and 22.00. Also, temporary accessible routes shall be provided as applicable in accordance with 521 CMR 3.10.

The subdivider shall protect all utilities and appurtenances installed from any and all damage until the entire subdivision is completed and approved as a whole by the Planning Board.

Any damage to these utilities and appurtenances prior to the approval by the Planning Board shall be repaired in a manner satisfactory to the Planning Board and DPW Director, the full cost of which shall be borne by the subdivider.

A description of provisions for phasing the project where one acre of area or greater is to be altered or disturbed:

A description of how the project owner will inspect the site during the course of construction to monitor the management of stormwater in accordance with applicable town, state, and federal regulations;

Plans must be stamped and certified by a qualified Professional Engineer or a Certified Professional in Erosion and Sediment Control (CPESC); and

Such other information required by the Permit Granting Authority.

The name(s) of the owner(s) of all components of the system.

Initial Site Inspection: prior to approval of any permit/plan (note, an inspection will also be completed by the Town's third-party expert engineer);

Erosion and Sediment Control Inspection prior to the commencement of any construction activity: to ensure erosion and sediment control measures are in place and stabilized, and to ensure erosion control practices are in accordance with the filed plan (note, an inspection will also be completed by the Town's third-party expert engineer);

Site Clearing has been substantially completed;

Rough Grading has been substantially completed;

Final Grading has been substantially completed;

Bury Inspections: prior to backfilling of any underground drainage or stormwater structures.

Close of the Construction Season;

Landscaping (permanent stabilization); and

Final Inspection. After the stormwater management system has been constructed the Applicant must submit a record as-built plan detailing the actual stormwater management system as installed. Such plans shall show compliance with the final approved plans by the Permit Granting Authority. The Permit Granting Authority or their designee shall inspect the system to confirm its "as-built" features match those depicted on the project plans. If the inspector finds the system to be adequate, the inspector shall so report to Permit Granting Authority which will issue a Certificate of Completion.

If the notice of violation or enforcement order was issued by an authorized agent and not by the PGA, the Property owner or its designee may appeal the decision of the enforcing agent to the full Permit Granting Authority within five calendar days of receipt of the written notice of violation or enforcement order. Failure to appeal with five calendar days shall preclude any further appeal.

If the Permit Granting Authority, or its authorized agent determines that abatement or remediation of adverse impacts is required, the order shall set forth a deadline by which such abatement or remediation must be completed. Said order shall further provide that, should the violator or property owner fail to abate or perform remediation within the specified deadline, the Town may, at its option, pursue a Court Order allowing the Town to undertake such work, and expenses thereof shall be charged to the violator.
