WHEREAS, on May 24, 2015, Stephen and Cecile Bassas, the Applicant, (all references to

which shall include and be binding upon the Applicant’s successors and/or assigns) submitted to

the Village of Mamaroneck Planning Board (“Planning Board”) an Application seeking a wetland

permit to allow the removal of paved area and construction of a new residence and patio (1,186

square feet) replacing the existing residence within the 100 foot wetland buffer (“Application”);

and

WHEREAS, the Applicants’ property is located at 1064 Bayhead Drive (“Property”),

situated within the R-20 Residential District; and

WHEREAS, the Applicant revised the plans to move the proposed residence five feet

out of the wetland buffer toward the road and is in alignment with adjacent homes in the

neighborhood. The Applicant has minimized the intrusion into the wetland buffer, which is

now 335 square feet. The application’s revisions provide a net decrease of total impervious

area of 3,710 square feet, including 1,162 square feet within the wetland buffer. The

removal of impervious surfaces within the buffer area includes the flagstone patio

surrounding the existing 660 square foot pool. All roof water will now discharge to the front

yard outside of the wetland buffer. The stormwater management plan as described in the

SWPPP prepared by Benedict Salanitro, P.E. dated March 9, 2015 will include 5 Cultec 330XL-

HD units located in the front yard outside of the wetland buffer. Inspection ports will be

installed over the Cultic units for regular maintenance and inspection. This proposal

("Project") is described and illustrated on the following set of plans dated May 13, 2015 as
