1. Approval of Minutes
The minutes of the meeting of January 23,2000 were read and approved as amended. •
2. 15 Briar Cliff Road
Referred by the Town of Mamaroneck Planning Board
This matter was referred to the Commission because the Applicant, Anthony DiMaggio,
intends to construct an addition to an existing house which lies in the buffer area of the
Sheldrake River, and is adjacent to the 100 year flood plain. The proposed addition will add
approximately 600 square feet of impermeable surface to the site. The Applicant intends to
install a 3 foot drywell, 6 inches below grade. The Commission noted the existing gravel
driveway and suggested that the calculations supporting the current drainage plan be

is
sufficiently conservative to incorporate the loss of permeable surface should the homeowner
later decide to pave the driveway. In the alternative,the Commission agreed to recommend a
restriction be placed on the site,preventing the paving of the driveway in the future. The
Applicant indicated a willingness to incorporate the paving of the driveway into the
calculations. Rather than ask the Applicant to appear before the Commission once again,the
Commission will ask the Planning Board to carefully check the calculations to make sure the
proposed drainage plan is sufficient
3. Cedar Island Sewer Connection
Referred by the Village of Larchmont Building Department
Because of the expansion of one of the homes on Cedar Island, a connection to the sewer on
the mainland is being installed. The line will run underground on the island, be strung along
the bridge to the mainland and connect at an existing manhole on the mainland. The sewer
line will be sheathed in PVC piping. The Commission asked that the portion of the line 1
running along side the bridge be contained in a metal sleeve for secondary containment. The
Applicant's representative, Vincent Hackett,explained that the system includes safeguards
against malfunctions, including air vents to prevent freezing. The Commission noted that the
project will involve extensive trench work on the island and asked that a detailed erosion and
soil control plan, incorporating best management practices,as required in the Village, be
provided to the Village for its approval. The Commission also asked that soil be stockpiled
on plastic on the land side of the trench and be covered with plastic sheeting at the end of
every work day.
4. 28 Iselin Terrace
Referred by the Village of Larchmont Building Department
This project involves the construction of two single family houses on a lot which was
previously occupied by one house which has recently been demolished. The plans provided
by the Applicant, Robert Frederick, showed that there will be two drywells to accommodate
one of the new houses,and three to accommodate the other. Commission member Mark
Godick expressed concern about the percolation test, in that the test pits used for purposes of
the pert test were dug to a depth of only 1.54 feet,whereas the drywells are proposed to be
4.5 feet deep. There is a risk that rock may be encountered at the greater depth,thereby
making the perc test inaccurate. The perc test should be performed under conditions which
more closely approximate the actual conditions. The Applicant also provided the
Commission with a tree and landscaping plan, which,he advised the Commission,had been
approved by the Larchmont Tree Commission. Thirty-one of the 55 trees on the site of 3 1/2
inches or greater are being removed. The Commission noted that the effect of the removal of
so many trees on the absorption of water at the site should be calculated. Frank Buddingh
also made several suggestions regarding the protection of the remaining trees during the
building process. Among these were to protect the root systems from soil compaction due to
the storage of building materials by placing at least 6 inches of wood chips under the tree
canopy, and using care that the installation of underground utilities avoids damage to the
roots_ It was further suggested that native vegetation be incorporated into the landscape plan.
Finally, the Applicant was asked to incorporate best management practices during
construction to minimize soil erosion.
