[Amended 11-3-2020 STM by Art. 3]
E. 
In addition to other fees for subdivision reviews, a fee is herein established to partially defray the cost of technical, legal and administrative services required for the review, processing and inspection of roads and streets. This fee is to be paid by the developer to the Town Clerk at the time of his application for road and street construction.
A. 
Arterial street. An "arterial street" shall be defined as a major thoroughfare which serves as a major traffic way for travel between and through a town.
B. 
Collector street. A "collector street" shall be defined as a street servicing at least 15 units of residential development or streets which serve as feeders to arterial streets and collectors of traffic from minor streets.
C. 
Local residential street. A "local residential street" shall be defined as a street servicing fewer than 15 units of residential development.
D. 
Planning Board determination. The classification of a proposed street shall be made by the Planning Board after its consideration of land use or a Comprehensive Plan adopted by the Town. Said determination may be made by the Planning Board prior to the formal application after submission of all information that may be required for that purpose.
A. 
Design standards shall be defined as paved streets with such appurtenances as curbs, esplanades, paved sidewalk(s), ditches, culverts, under drain and/or stormwater drainage systems. All proposed streets shall be designed and constructed to meet the design standards of this section.
(1) 
Proposed streets shall conform, as far as practical, to such Comprehensive Plan or policy statement as may have been adopted, in whole or in part, prior to the submission of the preliminary plan.
(2) 
All streets in the subdivision shall be so designed that, in the opinion of the Board, they will provide safe vehicular travel while discouraging movement of through traffic.
(3) 
The arrangement, character, extent, width, grade and location of all streets shall be considered in their relation to existing or planned streets, to topographical conditions, to public convenience and safety and their appropriate relation to the proposed use of the land to be served by such street. Grades of streets shall conform as closely as possible to the original topography.
(4) 
In the case of dead-end streets, where needed or desirable, the Board may require the reservation of a twenty-foot side easement in the line of the street to provide continuation of pedestrian traffic or utilities to the next street.
(5) 
Reserve strips controlling access to streets shall be prohibited except where their control is definitely placed in the Town under conditions approved by the Planning Board.
[Amended 5-24-2021]
(6) 
In front of areas zoned and designed for commercial use or where a change of zoning to a zone which permits right-of-way and/or pavement, widths shall be increased by such amount on each side as may be deemed necessary by the Board to assure the free flow of through traffic without interference by parked or parking vehicles and to provide adequate and safe parking space for such commercial or business district.
(7) 
Adequate off-street loading space, suitably surfaced, shall be provided in connection with lots designed for commercial use.
(8) 
Where a subdivision or limited access highway borders on or contains a railroad right-of-way or limited access highway, the Planning Board may require a street approximately parallel to and on each side of such right-of-way, as applicable, at a distance suitable for the appropriate use of the intervening land as for park purpose in residential districts or for commercial or industrial purposes in appropriate districts. Such distances shall also be determined with due regard for approach grades and future grade separations.
(9) 
Where a subdivision borders an existing narrow road (below standards set herein) or when the Comprehensive Plan indicates plans for realignment or widening of a road that would require use of some of the land in the subdivision, the subdivider shall be required to show areas for widening or realigning such roads on the plan, marked "Reserved for Road Realignment (or Widening) Purposes." It shall be mandatory to indicate such reservation on the plan when a proposed widening or realignment is shown on the Official Map. Land reserved for such purposes may not be counted in satisfying setback or yard or area requirements of Chapter 225, Zoning, of the Town Code.
(10) 
Where a subdivision abuts or contains an existing or proposed arterial street, the Board may require marginal access streets (streets parallel to arterial streets, providing access to adjacent lots), reverse frontage (that is, frontage on a street other than the existing or proposed arterial street) with screen planting contained in a nonaccess reservation along the rear property line or such other treatment(s) as may be necessary for adequate protection of residential properties and to afford separation of through and local traffic.
(11) 
Subdivisions containing 15 lots or more shall have at least two street connections with existing public streets or streets shown on the Official Map as such exists or streets on an approved subdivision plan for which a bond has been filed.

Hot bituminous pavement also shall be used on heavily trafficked streets, through streets and where deemed necessary by the Planning Board. Liquid asphalt may be used in more rural areas where the traffic volume is low and where through traffic is minimal. The final determination of the paving shall be made by the Planning Board.
B. 
Preparation.
(1) 
Before any clearing has started on the right-of-way, the center line of the new road shall be staked and side staked at fifty-foot intervals. Limits of clearing shall be marked by stakes or flagging distances from the center line shall be obtained from the cross sections.
(2) 
Before grading is started, the entire right-of-way area shall be cleared of all stumps, roots, brush and other objectionable material. All ledge, large boulders and tree stumps shall be removed from the right-of-way.
(3) 
Tree stumps and other organic materials shall be removed to a depth of two feet below the subgrade of the roadway. Soils which are designated as being poor or very poor for road fill by the Soil Suitability Guide for Land Use Planning in Maine (most recent version), shall be removed from the street site to a depth of two feet below the subgrade and shall be replaced where necessary with soils listed by the Soil Suitability Guide as being good or fair for road fill.
[Amended 11-3-2020 STM by Art. 3]
(4) 
Side slopes shall not be steeper than a slope of three feet horizontal to one foot vertical, graded, fertilized and seeded. Planting strips shall be lined at the rate of 10 pounds of a 10-10 fertilizer per 100 square feet or equivalent and seeded with a conservation mix meeting the standards of the York County Soil and Water Conservation District.
C. 
Bases and pavements.
(1) 
Bases.
(a) 
Aggregate subbase course. Gravel aggregate subbase shall not contain particles of rock exceeding four inches in any dimension; and
(b) 
Aggregate base course. Crushed aggregate base shall not contain particles of rock that will not pass the two-square sieve.
(2) 
Pavement joints. Where pavement placed joins existing pavement, the existing pavement shall be along a smooth line and to a neat, even, vertical joint.
(3) 
Curbs and gutters.
(a) 
Street curbs and gutters shall be installed as required by the Planning Board; and
(b) 
Curbs shall be vertical except when sloped curbs are specifically allowed by the Planning Board.
A. 
Adequate provision shall be made for disposal of all stormwater collected in streets and areas tributary to the street system and underground water through ditches, culverts, under drain and/or stormwater drainage systems.
(1) 
All stormwater systems shall be designed to meet the criteria of a twenty-five-year storm based on rainfall data from Weather Bureau records in Portland.
[Amended 11-3-2020 STM by Art. 3]
(2) 
Appropriate conveyances for outlets to drainage systems must be provided. Asphalt-coated steel culverts and asphalt-coated steel pipes or equivalent shall be used where drainage is required.
(3) 
In any case, the minimum pipe size for any storm drainage pipe shall be 12 inches. Catch basins of an appropriate size and type shall be installed where necessary and shall be located generally at the curbline. Catch basins shall be placed away from the line of traffic flow; however, they shall be adequate in design and strength to accommodate vehicle traffic.
B. 
Upstream drainage shall be accommodated by an adequately sized system for existing conditions and future potential development in the upstream drainage area or areas tributary to the proposed Town way. The adequacy of the proposed system(s) shall be determined by the Planning Board.
C. 
Existing or future downstream drainage requirements shall be studied to determine the effect of proposed drainage. The applicant shall demonstrate to the satisfaction of the Planning Board that the storm drainage will not, in any way, overload existing or future storm drainage systems downstream from the proposed street.
D. 
Where open ditches, channels, streams or natural drainage courses are used either to collect or discharge stormwater, adequately sized perpetual easements shall be provided and appropriate erosion control measures taken. No stormwater will be permitted to drain across a street or across an intersection.
E. 
Under drainage systems. Where subsurface solids are of the nature to require an under drainage system, under drains shall be installed and discharged not to degrade the environment. An under-drainage system shall be installed to properly drain all springs or areas where the groundwater level is too high and would cause a hazard to the stability of the roadway base.
A. 
All material used for storm drainage construction shall be in conformity with State of Maine Specifications for Highways and Bridges, most recent version. In addition, the quality of stormwater flows off the street shall be addressed. Retention of the 1/2 inch from a storm event for 24 hours by an oil and gas separator catch basin (properly maintained) or other stormwater quality improvement measures may be necessary, as determined by the Planning Board, to minimize or eliminate sediments, hydrocarbons or other contaminants from the stormwater leaving the right-of-way. Whenever possible, low-impact development standards (LID) shall be incorporated into the site design.
[Amended 11-3-2020 STM by Art. 3]
B. 
General construction requirements.

Manholes shall be provided at all changes in vertical or horizontal alignment and at all junctions. In straight runs, manholes shall be placed at a maximum of 400-foot intervals.
(4) 
When necessary, outlets shall be terminated in an end wall or concrete construction or shall be riprapped to prevent erosion or other appropriate measures taken. Facilities for energy dissipation shall be provided where necessary.
A. 
Erosion control. Procedures shall be undertaken, during preparatory, construction and cleanup stages, to prevent soil erosion and water pollution. A plan shall be prepared meeting the standards of the York County Soil and Water Conservation District.
B. 
Cleanup. Following street construction, the developer and contractor shall conduct a thorough cleanup of stumps and other debris from the entire road or street right-of-way.
C. 
Street names, street signs and streetlights. Streets which join and are in alignment with streets of abutting or neighboring properties shall bear the same name. Names of new streets shall not duplicate nor bear phonetic resemblance to the names of existing streets within the municipality and shall be subject to the approval of the Select Board. Street name signs shall be furnished and installed by the developer. The type, size and location shall be subject to the approval of the Planning Board. Streetlighting shall be installed as required by the Planning Board.
[Amended 11-3-2020 STM by Art. 3]
D. 
Entrance sign. A residential neighborhood, development or subdivision with clearly defined geographical boundaries may have one sign located at the primary entrance not to exceed 12 square feet.
[Amended 11-3-2020 STM by Art. 3]
A. 
Plans and illustrations submitted in accordance with § 240-10.1C (Plans) shall be designed and prepared by a civil engineer licensed in the State of Maine. No construction will be permitted until the Planning Board has approved the plans. No lot in a subdivision may be sold, leased or otherwise conveyed before the street upon which the lot fronts is completed in accordance with these standards up to and including that lot.
B. 
Utilities, where available, shall be installed prior to the street construction phase so as to avoid re-excavation of the finished street.
C. 
Prior to the commencement of each major phase of construction, the Director of Codes and Planning shall be notified.
D. 
Upon completion of street construction and prior to a vote by the Select Board to submit a proposed Town way to a Town Meeting, a written certification signed by a civil engineer licensed in the State of Maine shall be submitted to the Select Board, at the expense of the applicant, certifying that the proposed Town way meets or exceeds the design and construction requirements set forth herein.
A. 
Pursuant to the procedures set forth in § 240-7.1L, prior to the time of the approval of the final plan application, the applicant shall tender either a certified check payable to the Town or other such surety or performance bond payable to the Town in the amount of 100% of the cost of streets and completing all grading, paving, storm drainage and utilities specified in the application.
B. 
Prior to the release of such check, bond or other surety, the Planning Board shall determine to its satisfaction, in part by the written certification required pursuant to § 240-10.8D, that the proposed street and any other improvements meet or exceed the design and construction requirements set forth in the application and these regulations.
