Committee forwards ZTA 2403 to full council, keeps life‑science focus and several technical fixes

The Montgomery County Council Planning, Housing, and Parks Committee on Jan. 27 voted to forward Zoning Text Amendment (ZTA) 2403, which would create a Great Seneca Life Sciences (GSLS) overlay zone, to the full Council with a 3‑0 committee recommendation.

The measure implements recommendations from the Great Seneca master plan and would allow greater height and density in the plan area in exchange for publicly beneficial amenities, change parking rules in the overlay and use a tiered “incentive density” system to award additional floor‑area ratio (FAR) credits for public benefits.

Council staff said the ZTA makes optional‑method development available for projects above 0.5 FAR and sets a tiered credit system that can award between 0.25 and 1.0 FAR depending on the cost and complexity of the public benefit. It also removes some existing caps by stating limits that previously capped residential uses at 30% and retail at 15% would not apply within the overlay, allowing more mixed use than the current LSC underlying zone.

Why it matters

The committee described the overlay as a primary implementation tool for the Great Seneca plan, intended to attract and support life‑science employers and related development while encouraging a mix of housing, infrastructure and open space. Staff noted the overlay could increase greenhouse gas emissions at full build‑out because surface parking lots would be redeveloped and more people would live and work in the area, but that many incentivized public benefits in the ZTA are intended to reduce emissions.
