Project: Raze and rebuild existing single family home

dated 9/4/2015, Site plan dated 9/15/2015
Rich Kirby (LEC Environmental) Mike Novak(Meridian Engineering), and Bill Eclyshymer
(owner)
Mr. Kirby presented a proposed project for a raze and rebuild of a single family home. The
proposed house would be in generally the same footprint as the previous house and will be
further away from the wetland. Mr. Kirby explained that there is a drainage easement that runs
through the property so that was a factor as to where they could place the house. Because the
groundwater is higher than they would have liked to see, Mr. Kirby explained that they decided
to use a detention pond in the back yard rather than an underground infiltration trench which
would be mowed twice annually. There would be some tree removal and tree protection would
be used.
Concerns and comments from the commission:
The commission questioned whether there are proposed pump calculations for the detention
pond. The commission wanted an annual recharge calculations report.
The commission stated that the town engineer wanted an investigation into where the easement
pipe is located.
The commission questioned whether the house location could be moved.
The commission questioned the drip line of a large silver maple in the back yard and wanted to
be ensured it would be protected.
The commission stated that the detail of the basin needed to be clarified.
The commission expressed concern over the type of vegetation that would be able to grow in the
detention basin area.
The commission requested how the calculations were made regarding the drainage of the
detention pond.
The commission stated that they would want to see revised plans showing increased tree
protection, crushed stone detail, infiltration rate, the changes in the seed mix for the detention
basin, and detail of the topsoil before they would approve the plan.
Motion to close the hearing moved by Mr. Langseth and seconded by Mr. Beuttell. Vote 5-0 in
favor.
