condominium association. Foundation systems of the existing condorairliurn
would intercept any perched water table or any artificial water table created by
groundwater T.o4nding in this area. That result could lead to sTormwater
infiltrating basernent systems where these types of problems do not exist today. If
the groundwater system is allowed. the applicant should be required to provide an
interceptor trench along the property boundary including an impervious barrier on
the downstream side of the trench which would eliminate any opportuniry for
subsurface groundwater flow to create an impact ou abutting properties. Where
this final intereeptor wench would flow to is a further question. I strongly suggest
that you pay particuLar attention to these issues since I don't feel that they have
been adequately addressed ai this point.
Farther, the applicant has indicated, which is suPPPorted 5}r the manufacturer's technical
dam that #hese types of systems require agressive maintenance. A bond securinig the
rmmntenance, repair and replacement together 1,6ith a eouniermeasure plan should be
submitted before this agressive systcm is allowed.
I would be happy to discuss this matter furthar ',i-ith anyone who has any questions
rcgardinb this matter.
