Maps and plans should:
Indicate both existing and proposed site conditions, including temporary construction impacts, any replication areas, and/or other mitigation measures.
Identify the proposed activities and their location relative to the boundaries of each wetland resource area and buffer zone (if applicable).
Technical data should be submitted to support the plans in narrative form, with calculations submitted as necessary to substantiate the designs proposed.
The following standards and design specifications are intended to provide the BCC with the minimum amount of data necessary to determine the impact of a proposed project on wetland resource areas and/or the ability of said resource area to provide documented functions and values. The BCC may find it necessary to request additional site-specific information to adequately determine the effect of the work on resource areas.
All drawings shall be drawn with the title designating the name of the project, location and the names of the persons(s) preparing the drawings, and the date prepared (including the latest revision date).
Site plans shall be drawn at a scale of 1”=10’, 1”=20’, or 1" = 40'. HOWEVER, plans may be reduced in size to allow for submission of 11” X 17” paper plans. Additional plans with greater or lesser detail may also be required if such plans would provide valuable information to the BCC in its review. The BCC may request a plan at a different scale for large properties or unique circumstances.
Property boundaries and abutters from the most recent information on record at the Assessor's Office.
All existing natural and man-made features including tree lines, rock outcrops, fence lines, foot paths, overhead and underground utilities, and drainage structures.
Elevations of all natural and man-made drainage structures, waterways, and wetlands (as defined by the Wetlands Protection Act).

All wetland resource areas, including the 100-foot Buffer Zone, and flag numbers of all field delineated wetland resource areas.
100 year flood elevations of all natural and man-made waterways and water bodies as determined from the FEMA Flood Insurance Rate Maps and Flood Boundary and Floodway Maps. Where the floodplain of wetlands and water bodies have not been mapped by FEMA, hydrologic and calculations may be required, prepared by a registered professional engineer to determine the boundary of the 10 and 100-year floodplain.

Hydrologic calculations showing the full-flow capacity and velocity of all water courses, open and only sometimes closed channels, and storm drains flowing into, on and out of the property.
An 8 ½ " X 11" photocopy of the United States Geological Survey (USGS) topographic quadrangle indicating the location of the proposed activity and the outline of the area in which the activity is located.
Drawings shall be stamped and signed by a Registered Professional Civil Engineer or Registered Professional Land Surveyor of the Commonwealth of Massachusetts.
Plans depicting proposed structures, drainage systems, and/or a subsurface sewage disposal system must be stamped by a Registered Professional Civil Engineer of the Commonwealth and receive the approval of the Boston Water and Sewer Commission.
The next public hearing will take place on Wednesday, December 11, 2013 beginning at 6pm.
