A proposed development or subdivision, or land which requires extensive or substantial filling to qualify for development or subdivision, shall proceed in the following manner:
A. 
Extensive or substantial filling shall be considered as fill in excess of three feet in depth required over the general area, or a substantial portion of the land, in the development or subdivision, especially in the areas of proposed dwellings and sewage disposal leach fields, if such fields are planned.
B. 
The master plan shall be submitted as required, and Planning Board action taken on this plan in the prescribed manner.
C. 
A preliminary plan shall be submitted to the permitting authority for preliminary approval of the layout only. With this plat, there shall be submitted a contour plan of the entire property showing all existing contours at not greater than one foot apart.
D. 
Such drawings shall be submitted in duplicate. From the drawings submitted, the permitting authority will determine the grade elevations to which the land must be raised by means of fill, and will so mark one set of the drawings for return to the developer.
E. 
If preliminary approval of the layout is granted, the required fill shall be placed and properly compacted. The permitting authority will require the lapse of at least one year after all fill has been completed satisfactorily before further processing of the proposed development or subdivision.
F. 
All fill used shall consist of clean material, and any used at a level 30 inches below final finished grade shall be particularly of a pervious nature, and subject to inspection and approval by Administrative Officer.
G. 
After fill has been placed and the required time period has elapsed, a revised preliminary plan and contour plan drawing shall be made, at which time the percolation and groundwater level tests, if required, shall be made. These tests shall be made after all fill is completed and at the expiration of the time noted above.
H. 
Processing of the preliminary and final plans from this point shall proceed as set forth in these regulations.
Land which is required for streets, sewer installations, storm drainage installations, public recreation areas, conservation areas or any other public purpose within a proposed development or subdivision shall be conveyed to the Town of Barrington by deed or other acceptable instrument as a condition of approval by the permitting authority. The approval of the final plat/approved land development project plan/approved development review plan by the permitting authority shall be deemed the acceptance by the Town of Barrington of all such lands, but shall not impose any requirement upon the Town of Barrington to maintain or improve such dedicated areas or improvements until such maintenance or improvement shall have been authorized by the Town Council in accordance with state law and local ordinance.
A. 
The Planning Board may provide for the review of preliminary and final plans, and the construction of major land developments and subdivisions, in phases. This shall also include the establishment of a timetable, rate or phasing requirements for the construction of inclusionary dwelling units for affordable housing production. When development phasing under these regulations occurs, the following is required:
(1) 
Approval of the entire site design first as a master plan; thereafter the development plans may be submitted for preliminary and/or final review and approval by phase(s).
(2) 
General standards and regulations for determining physical limits of phases, completion schedules and guaranties, for allowing progression to additional phases, for allowing two or more phases to proceed in review or construction simultaneously, for interim public improvements or construction conditions and for changes to master or preliminary plans.
(3) 
Other provisions as necessitated by local conditions.
B. 
The master plan documents may contain information on the physical limits of the phases, the schedule and sequence of public improvement installation, improvement guaranties and the work and completion schedules for approvals and construction of the phases.
C. 
The master plan shall remain vested as long as it can be proved, to the satisfaction of the Planning Board, that work is proceeding on either the approval stages or on the construction of the development as shown on the approved master plan. Vesting shall extend to all information shown on the approved master plan documents.
When required in an application subject to these regulations, during the course of review of an application, or as a condition of approval, a traffic impact assessment report shall include existing traffic conditions in the vicinity of the proposed development, the volume and effect of projected traffic generated by the development and measures to mitigate adverse impacts on traffic conditions and pedestrian access and safety. The report shall be in accordance with the following format and scope:
A. 
Existing conditions.
(1) 
Roadway geometrics:
(a) 
Lane and shoulder widths.
(b) 
Locations of intersections and curb cuts.
(c) 
Posted speed limit.
(2) 
Existing traffic volumes:
(a) 
Morning and afternoon peak flows and travel directions.
(3) 
Accident data: record of accidents available from either the State Department of Transportation or the Barrington Police Department for the previous three years.
B. 
Projected traffic.
(1) 
Area traffic growth: increase in traffic volumes resulting from other development, based on an average increase of the existing volumes for every year up to the selected design year.
(a) 
Morning and afternoon peak flows and travel directions.
(2) 
Site-generated traffic growth: vehicle trips from the uses created by the proposed development, based upon the trip generation factors published by the Institute of Transportation Engineers.
(a) 
Daily trips and morning and afternoon peak flows and travel directions.
(3) 
Total traffic growth: site-generated growth superimposed on area traffic growth.
(a) 
Morning and afternoon peak flows and travel directions.
C. 
Traffic analysis.
(1) 
Capacity analysis: existing and future level of service (LOS) based upon the procedures contained within the 1985 Highway Capacity Manual.
(a) 
Morning and afternoon peak hour LOS at all impacted intersections.
(2) 
Sight distances:
(a) 
From all proposed curb cuts within project impact area.
D. 
Mitigation measures.
(1) 
Roadway geometrics:
(a) 
Roadway widening or addition of travel lanes.
(b) 
Locations of, or limits on, curb cuts.
(2) 
Traffic controls:
(a) 
Proposed signage and traffic signals.
