Buffer zone actIvitIes- no taking of wetlands.
Removing roadway away form Wetland #1 to upland areas.
No alterations of wetlands 80% of site will remain undeveloped
detention basins- been designed to dIscharge into large swale areas
that are designed to dlsch rge Into one ~ear storm event. Have

1-10-100 year storm control.
No increase peak flow. Flows into and out of wetland changing 10%
flow into wetlands- decrease winter months not going to dryout,
increase in summer.
3 wetlands development around them but no changes to
them.
Around water flow pre and post development in N.O.I.
storm water quality- impacted by development addressed the problems
large swale systems-detained in detention basin. Energy dissipators
through adjacent 40 foot upland vegetation intlows away from out flow
areas anticipate vegetation will grow to maintenace schedule.
Blasting study done, range of blasting 10 foot tIght bedrock. No
blasting taken place adjacent to wetlands. Small gravel walkways
around pond monitor blasting pre and post construction.
Conditions passed out by Paul who proposed Order of Conditions.
Siltation to Wetlands disturbed slopes-seeded
No chemical de-icing catch basin checked for siltation detention basin
outlets checked and cleaned weekly- staff will be on site to maintain.
Report every 30 days in writIng to commiss~on. Lengthen pipes up Witch
Lane flagging indicates no bordering vegetation wetland in that area.
15 feet of pipe to existing culvert
Bill~ Little more detail on wetland 1 and 2.
Paul: Adding 15 feet of pipe to both wetlands.
Nancy: Is there a weir?

George: pollutants why is there a difference?
Paul: Not that many vehicles
George: Many cars will be sitting in parking lot.
Paul: Have calculated trips National Survey Control from solid
material MDC trap and maintained catch basin.
Paul: Have designed the best system we can regarding pollutants.

Paul: From 85 down tCJ 65 apprCJximatley 300 feet.
Vinnie: What amount of flow will the detention basin take away!
Paul: Can't tell what the total % Df flow street and roof runoff. 80%
remaining undeveloped.
Peter: Surface runoff mostly rainfall
Paul: Moved buildinqs back-driveway upland area.
Peter: Where in volume 2 post run-off
Paul: 3 sub-drainage areas flow into wetland #1. Will have one of the
engineers look it UP

Sizable amount of blasting to adjacent wetlands should be a concern to
the commissIon. Was 1 year event utilIzed for all the wetlands.
Paul: The whole site.

Steve Crain: Math not available of pollutants caused by auto

Paul to Ray I believe I controlled all the potential wetlands
Renee: Loading dock discharge W,#3
Paul: All silt barriers will be in place to control area.
Renee: Vegetation around wetlands- for wildlife

testing regarding blasting-Bond be used to be sure people don't lose
their water. revised noi
Paul: Doesn't think blasting an issue he should answer, but the

Renee: Radon active gases have you check liquid goes into ground very
concerned because of wells.
Paul: Haven't tested for Radon
Renee: Drainage
Paul: Post construction run off throughout project have changed but
maintained pre and post runoff.
Paul: Depth of boring did not blast further than depth.
Renee: letters submitted to commission about species.
George: Plan #'s on showing depths of bedrock post development ground
level or basement.
Paul: is no basement slab.
Depth required by engineers to set slab correctly. 2 floors down.
George: above bedrock detention basins how is it done. installation of
detention basins.
Paul: No blasting to take place and when the installation of detention
basins occurs. Another option increase grade of berm.
Peter: Does any imprevious surface into wetlands.
Paul: No-all overland flow
Paul: Street drainage is controlled through' catch basins
Peter: Roof drainage from 1 area what about the other area.
Paul: By the elevation of the plan all the water goes toward the
streets.
Peter: Is there a berm along the street? Sheet F don't see berm
Paul: Catch basins don't work will with outa berm
Granite curb part of design
Peter: counts six catch basin dischargInq into wetland #1 needs to be
clarified.
Nancy: High point of land changed by blasting wetland #1 has changed
will it dry up?
Paul: drainage area changed collection point moved-retained surface to
maintain water- maintained flows into wetland. post development water
shed Map.
Peg Brady: Mass Audubon: submitted letter addressed to Ray Bouchard.
Contamination coming from the outside 100 buffer zone. No development
beyond 300feet boundary. ActIvities outside 100 feet that will affect
wetland
Contamination to stream no net increase pre and post development.
Chemicals herbicides pesticides.
George: you said research done outSIde the 100 foot buffer zone
Peg: Yes can submit information about buffer zone
Ray: May not that Conservation Commission has Jurisdiction outside
buffer zone.
Steve Leonard: ActiVIty outside 100 feet jurisdiction can be taken by
