517 Walnut Street- (Section 4, Block 54, Lot 13A) Located in the R-5 Zoning District - Subdivision Application

***

The Applicant proposes a lot line modification to turn three existing lots into two, create three off-street parking spaces, and construct a perimeter privacy fence as permitted by Mamaroneck zoning (§342-14.C). The three existing lots include 517 Walnut, an adjacent vacant lot, and 510 Pine, which abuts the rear of the vacant lot. All three lots have the same owner. The Application proposes to create three off-street parking spaces for the 517 Walnut Street lot by apportioning 822 square feet of the vacant lot along the Walnut Street road frontage to the 517 Walnut Street lot. The remaining 5,235 square feet of the vacant lot would then be combined with the 510 Pine Street lot to create a larger rear yard. This would deem the existing vacant lot unbuildable. There is an existing nonconforming lesser side yard width (5 feet versus the minimum 6 feet) but this would not be changed or made any more nonconforming by the action.
