A DEP number has not been issued yet. Questions from the Commission: — What direction does the driveway drain? Concerned about an increase in the rate of water across the property line. — Is there a post-construction replanting plan? Responses from the Representative: — The intent is for driveway runoff to drain towards the catch basin which is connected to the infiltration system. — The Applicant has a standardized landscape plan and will not be adverse to a Condition incorporating specifically sized trees or native plants in the Order of Conditions.

A Condition will be added that the path is to be rerouted outside of the 25-foot buffer zone to the extent possible. On a motion by Ms. Samuels and seconded by Ms. Dohan, the Commission voted 6-0 by roll call vote to issue a Negative Determination with Conditions.

Ms. Buczynski stated that there is a slight increase in the rate of the 2 year storm event peak runoff rate, however an overall reduction in the overall volume for the 2 year storm event. The Cotting School does not plan to treat the walkways. Towards the northern side of the site, where there is a steeper slope, the stormwater will continue to runoff down the slope and on the eastern side it will continue to run along the grass towards the wetlands. Comments from the Commission: — Is the proposal to take off the current pavement or just add another layer? Responses from the Representative: — Whether or not to take off the current pavement or add another layer is to be determined; however, if removal the excess material would be taken off site immediately. Ms. Buczynski asked if erosion control should be installed and a limit of work line, or if the proposal includes enough maintenance that it would not be necessary. Mr. Langseth responded that if there is no stockpiling of materials then no erosion control would be necessary. On a motion by Mr. Langseth and seconded by Mr. Beuttell, the Commission voted 6-0 by roll call vote to close the hearing.

Can you provide that for the next meeting? — The Commission has occasionally allowed a plan without test pits but it is entirely at the risk of the Applicant if approved. — Given the unnatural hydrology of a raingarden, don't believe it's a one for one replacement of a no-disturb buffer zone.
