Neighbors produce shadow and stormwater studies opposing 47 Montgomery accessory building placement
Summary
Adjoining owner and neighbors submitted a shadow-impact exhibit and a stormwater analysis saying the proposed 32-foot structure on the lot's north edge would cast prolonged shade and could increase runoff onto an adjacent lower yard; they requested survey and engineer review.

Adjoining owner Michele Greig and multiple neighbors submitted technical and narrative materials arguing the proposed accessory building at 47 Montgomery Street would have significant localized impacts.
Greig's shadow exhibit shows afternoon shadows extending 20–100+ feet onto the adjoining property on representative dates (May–October), and her filings note an approximately six-foot elevation difference that increases effective shading. Greig wrote the Board that the structure would cast a "continuous band of shadow" because it runs roughly 32 feet along the shared boundary.
Greig's stormwater analysis estimates that a 1-inch rainfall on an approximately 805-square-foot roof could produce roughly 475 gallons of runoff and warns that compacted fill and the site's slope could convey concentrated runoff downslope to the neighboring property. She asked the Board to consult the Village Engineer and to require on-site stormwater measures or relocation of the structure.
