Board of Health reviews septic plans and inspections
Lowell Road 40B
Engineer George Dimakarakos and attorney Michael McCarron presented the final septic plans to the Board of Health (BOH) on the 40B project at 302 Lowell Street, known as Laurel Hollow. Consulting engineer Rob Frado said that there were "just some minor issues which George has addressed" in the latest version of the design. Dimakarakos has added four dry wells for roof drainage requested by the Conservation Commission. Frado noted that the additions have not affected the septic design.
Frado expressed concern that the snow storage area designated in the center of the cul-de-sac was covering a large area of the leaching field. Dimakarakos explained that the center area was shared by different leach fields with no one leach field being entirely under the snow storage. Frado pointed out that the Dbox (distribution box) was placed so that there would be no snow storage on top of it thereby making it accessible in an emergency. Board member Michael Holland explained that the state law Title 5 allows a driveway to be placed on top of a leach field.
Abutter John Brewer of 280 Lowell Street asked if the design had a reserve area in case the septic system failed. Dimakarakos said yes and pointed the area out to Brewer.
The BOH was asked to approve two plans which were very similar. The 40B project will have two condominiums with separate water and septic systems. The two condominiums were created to get around the need for a public water system if a single well was used to supply all the dwellings.
The board voted approval of the two septic systems with the following conditions:
· There will be no pump water softener backwash allowed into the roof dry wells.
· A Title 5 inspection must be done on the system every three years or whenever one of the units changes ownership
· No landscaping will be permitted which impedes access to the Dboxes
· BOH will see the water management plan after drilling the wells but prior to issuance of the building permit. However, this will not take the place of the peer review.
152 South Street
Engineer Drew Garvin of R. Wilson Associates explained the need to drill a well 76 feet from the septic system tank and pump chamber instead of the minimum 100 feet required by Carlisle bylaws. Garvin explained that the slope was too great and the soil too rocky to get a well digger in to drill further than 76 feet.
Abutter Richard Bissell of 145 South Street complained that he had received notice of this hearing but got no response to his questions as to what the hearing was about. Bissell was concerned that his well might be impacted by the drilling of a new well across the street. Mike Holland explained the well drilling process to Bissell and expressed his opinion that the Bissell's well would not be affected.
The BOH voted to approve the waiver.
115 Partridge Lane
In preparation to sell this property the owner had filed with the Conservation Commission for a waiver of distance to bordering vegetative wetlands (BVW). ConsCom Adminis-trator Sylvia Willard had viewed the wetland and delineated the BVW boundaries differently than had been assumed at the time of the original permit. The edge of the wetland could not be determined at that time because of snow. The new revisions of 72 feet, Dbox to BVW, and 40 feet, tank to BVW, still meet the Title 5 requirements.
The BOH granted an amendment on the previous waiver rather than going through the procedure of a new hearing.
Daisy's Market Title 5 inspection
Daisy's market has failed a Title 5 inspection of its septic system. The tank, which was previously pumped in 1999, was found greasy. The alarm was functioning but not secured, and the Dbox was not in compliance, though nothing was backing up or breaking out.
The BOH decided to notify the Department of Environmental Protection (DEP) and request that the system be pumped more often. Frado is going to examine the water meter to figure out the units of measure so as to calculate the flow rate from the water meter readings supplied by Daisy. The BOH will then notify Daisy's how often the tanks must be pumped.
