Board gives neutral recommendation on Mulligan Lane garage height after steep‑slope review

At a May 21 work session the Greenburgh Planning Board reviewed a steep‑slope permit and related zoning variance for a proposed detached two‑car garage at 50 Mulligan Lane. The project requires a steep‑slope permit because approximately 615 square feet of the site’s 35%+ slope would be disturbed, exceeding the 500‑sq‑ft threshold that triggers Planning Board review.

Applicant’s representative presented grading plans, a Cultec stormwater infiltration system sized to the town’s standards (the applicant’s design referenced a 25‑/50‑year design standard depending on code language and staff guidance), and building elevations. The garage includes a non‑habitable loft the owner intends to use as an art studio; the applicant emphasized it will not be used as a dwelling unit. The applicant also proposed to replace existing asphalt driveway surface with pea gravel and to install evergreen screening to reduce year‑round visibility from lower properties.

Board members asked whether the new garage would appear taller than the existing house when viewed from the road and requested photos and landscaping mitigation; the applicant agreed to provide evergreen screening and to investigate pervious paving options. After discussion the board moved and approved a neutral recommendation to the ZBA on the requested height variance, noting the applicant’s willingness to work on screening and pervious surfacing.

What’s next: The applicant will submit materials to the Zoning Board of Appeals for a height variance; planning staff will work with the applicant to finalize a landscaping/screening plan and confirm the stormwater details ahead of any building‑permit submission.
