Case Study pdf (133 KB)	Step Pool Storm Conveyance System Design and Construction in Enosburg Falls, Vermont Stone developed comprehensive stormwater management plans (SWMPs) for eight communities in Franklin County, including the Village of Enosburg Falls, while working for the Friends of Northern Lake Champlain (FNLC). Each SWMP identified a suite of high priority stormwater management projects, including a stormwater outfall near the Enosburg Village Garage.. The outfall drains approximately 11 acres of largely impervious residential area in the downtown. Improvements to the channel below the outfall had been made in the 1990s as part of a sewer separation project, but heavy sediment loads, and a lack of proper maintenance had led to clogging of the stone-lined channel. Recently flows had begun to leave the banks of the existing stone-lined channel, causing significant erosion and damage to a walking trail.

Case Study pdf (248 KB)	Integration of Stormwater Best Management Practices into Land Development Regulations In 2005, the city of South Burlington became the first in Vermont to implement a stormwater utility as a means to finance and provide ongoing stormwater system maintenance, upgrades, and technical support. Since the utility's formation, South Burlington's City Council has adopted standards and provisions in its Land Development Regulations (LDRs) for surface water protection and stream buffering, for construction and erosion control, and for site design, snow storage, landscaping, and trash containment. However, there are many other opportunities to include sensible stormwater management practices in the LDRs.
