Planning Board approves Langley Cove site amendment after debate over added parking and runoff
Summary
The board approved a site‑plan amendment at Langley Cove that removes underground parking for two buildings and increases surface parking. Residents warned that additional pavement could increase sediment delivery to Langley Cove; staff said detention ponds and an AOT amendment reviewed by NH DES address runoff concerns.
The Laconia Planning Board voted Dec. 16 to approve an amendment to the Langley Cove development (PB2026‑563) that removes proposed underground parking in two 35‑unit buildings and replaces it with expanded surface parking. The applicant said the change increases overall external parking capacity while keeping the same unit count; the planning staff presented conditions requiring revised plans, approvals and inspections and stated the AOT amendment with the New Hampshire Department of Environmental Services (DES) must be finalized before full approval is effective.
At the hearing the applicant said existing detention and drainage infrastructure has been constructed to accommodate the additional impervious surface, and that the project team updated drainage calculations and will seek an AOT amendment with DES. The applicant said off‑building slab‑on‑grade construction and larger surface parking produced an estimated net increase of roughly 26,000 square feet of impervious surface in the amended area, but overall green‑space calculations remain within the approved master plan because other parcels remain untouched.
Residents, including Keith Dubey and Emily Sharpett, voiced opposition and concern that added pavement uphill from Langley Brook could increase runoff and sediment reaching Langley Cove; Dubey and others also described long‑term sedimentation in the cove and a denied dredging permit for private actors pending upstream remediation. Staff responded that DES reviews AOT permits and that the amendment will incorporate DES requirements and be subject to regular SWIFT reports and public‑works inspections. The board discussed detention‑pond sizing, outlet routing through wetlands and the potential downstream effects; some members voiced strong reservations about adding more pavement but staff and applicants emphasized completed outlet infrastructure and updated calculations.
After discussion, a motion to approve the amendment with the staff‑recommended conditions passed. The approval is conditioned on submission of revised plans, final AOT amendment sign‑off by DES, required municipal inspections and recording of final plans. The board also noted the project is vested under RSA 674:39 if active and substantial development is commenced within required time frames.
Next steps: the applicant must secure DES AOT amendment approval, submit revised plans and submit performance guarantees and mylar plan sets for recording; DPW and Planning will monitor site work and stormwater controls.
