Ralph Levy, project manager for the Yacht Club, reported that the silt will go into a dewartering container.  He noted that the silt does not need to be tested and that they will contact Hayward in advance as to where the silt will go.

 

Levy informed that DPW does not have cameras to investigate the outfall pipe before and after the project is completed.  But DPW will provide a steel plate to place over the outfall area during the project construction.

 

Levy clarified that they will be using ?waddles? not cori logs for erosion control.  They will be using hay bales or hay logs, depending on their price.

 

Levy said that the site will be cleaned each night.

 

Hayward reported that he spoke to Nancy White at DEP and that she indicated that the project met all DEP standards.  He did note that the project would have to be reviewed by DEP if the boat launch was expanded from proposed.  Hayward informed that Jay Pelletier needs to be called the day before the project begins to determine the weight over the outfall to protect it.  DEP was concerned about the project impact on the herring run.  However, the timing of the project will not impact it.

Martin clarified that the hay bales do not need to run the length of the stream.

 

Pallotta McDermott inquired why no sampling was needed by DEP.  Hayward responded that Heidi Davis of DEP indicated that if the material removed was less that 100 cubic yards no sampling was required.

 

Rose suggested that all site contractors get the construction plans.

 

Vote:  Martin moved to close the Public Hearing. Bering seconded the motion.  The motion was unanimously approved.

 

3.                  DCR Vegetation Management Plan Update ? 321-0131/WWO-07-12 ? Richard Scott, District Park Manager

 

Richard Scott reported that knot weed was removed from the area.  Mowing occurs every 14-21 days and the schedule was posted on the website.  During the previous year graffiti removal, trash removal, mowing and pruning were undertaken.  Scott informed that the DCR worked with Charles River Conservancy and Friends of the Waterfront in volunteer improvement efforts.  At 354 Charles River Road a guard rail was removed and that efforts in that area would be undertaken as the steps were hazardous.  He also commented that the SCA-AmeriCorps would be sending a crew of four to work on special projects- Charles River Road between the Yacht Club and Greenough Blvd. was selected as their special project.  Scott reported that the Founders Monument was completed and a dedication was scheduled for June. He noted that the monument was vandalized with used motor oil and that Daedalus, Inc. repaired the damage.   He commented that the Park Serve Day was a success.  He explained that the Watertown Pool will be managed by another DCR district. 

 

4.                  Public Hearing ? NOI- 175 North Beacon Street, 321-0138/WWO-09-05 for the installation of a new storm water management system for the new building and parking area which will be route drained into an existing pond on the Perkins School campus.  Perkins School, owner.

 

Stephen Garvin, Samiotes Consultant and applicant representative, submitted abutters list green cards.  Pallotta McDermott raised concerns about this proposal since there is an existing OOC for the pond improvement.

 

Garvin responded that he was seeking CC guidance on how to reconfigure, treat and utilize the site to handle water drainage resulting from a proposal by Perkins School to add a building, and parking lot.

 

Garvin informed that they will propose a green roof and a site design that will decrease runoff by 10%.  He assured that no untreated flow will go into the resource area.  The pond will be used to handle volume only. He indicated that an Operation and Maintenance Plan will be developed.  He said that the outlet will be connected to the existing outlet.  He informed that Perkins sweeps its parking lot more often than required because of the population they serve.  Garvin commented that the infiltration devise will be located outside the courtyard area.

 

Hayward expressed appreciation over the storm water drainage proposal and that it answered all his concerns.    He recommended that they meet with Mee to review the project.

 

Rose inquired if there were any designs to channel runoff to the parking lot trees.  Pallotta McDermott expressed concern that any proposal be sensitive to the Perkins population.

 

Fairbairn questioned where the rain gardens were.  Garvin responded that there were none but they could be considered.  Fairbairn wanted to see more surface drainage and drainage to the trees.  Rose wanted to see more infiltration.  Garvin indicated that he had to remove 44% TSS from the parking lot.

 

Martin was satisfied with the water treatment plans.  However, he wanted to know the velocity of the water as it discharged into the pond.  Garvin reported that the pipe is flat and that efforts would be in place to slow the velocity.

 

Vote: Rose moved to close the Public Hearing. Martin seconded the motion.  The motion was unanimously approved.

 

5.                  Request for Certificate of Compliance ? 550 Arsenal Street (Target)321-0128/WWO-07-11

Department of Conservation and Recreation, owner.

 

Rich Corsi, DCR Planner, reported that the 2002 Master Plan identified the following improvements to the Nonantum Road area: that the parkland area be increased, that pavement area be decreased, that the driving lanes be increased to 11? wide with a 3? shoulder to allow the road to be shared with bicycles.  The present plan will include a historic lighting, 6 to 8? planting strips for trees, and improvements to the storm water management.  Corsi reported that the project is expected to be advertised in early summer.  The project will be funded through Mass Highway for 6 million dollars.  Approximately 44,000 square feet of pavement will be removed from the entire project.  The project will improve safety. Presently, there are no shoulders or curbs on Nonantum Rd.  Corsi informed that all catch basins will be replaced and that bio infiltration systems will be installed. 

 

Martin inquired about the frequency of sweeping calculations.  Hayward informed that a revised copy was submitted to the CC Office, Hayward and Rose which included the calculations.

 

Rose requested details for the proposed catch basins. 

 

Corsi noted that the construction schedule is to begin in the Fall and be completed in 18 months.
