BZA permits deck encroachment into stream buffer; owner to submit planting mitigation

Mar 17, 2026

A Johns Creek variance (V-260002) will allow a deck encroachment into the city's stream buffer at a 0.362-acre lot; staff said the net increase in impervious surface within the buffer would be about 166 square feet and required a planting/mitigation plan before permit issuance.

The full story

The Board approved V-260002, allowing a measured encroachment into the city's stream buffer to replace and extend an existing deck at a house in a Community Unit Plan district. Staff said the lot was originally platted under earlier rules and that changes to the city's stream-buffer regulations left much of the property within the current buffer; the recommendation allowed a limited encroachment and required a planting/mitigation plan as part of the building permit.
