a. Stabilization is not required if work is to continue in the area within the next 24 hours and there is no precipitation forecast for the next 24 hours.

b. Stabilization is not required if the work is occurring in a self-contained excavation (i.e.

no outlet) with a depth of 2 feet or greater (e.g. house foundation excavation, utility trenches).

3. No more than 2 acres of land may be disturbed at any one time.

4. Inspections shall be conducted at least once every (7) calendar days and within twenty-four (24) hours of the end of a storm event resulting in discharge of Stormwater from construction site.

5. If there is a discharge of visibly discolored stormwater from the construction site or from the construction site to waters of the State, the permittee shall take immediate corrective action.

6. If, after completing corrective action, there continues to be a discharge of sediment from the construction site to waters of the State, the permittee shall notify DEC by submitting a report within 72 hours of the discharge.

1. INTRODUCTION

1.1. Existing Project Description

A stormwater study was developed for the Greater Stonehedge Stormwater Committee and the City of South Burlington in 2007. According to that report, “The Stonehedge development, located off of Spear Street in South Burlington, had been experiencing stormwater drainage problems for a number of years. Changes in the watershed and aging infrastructure have resulted in damage to personal and city property, safety issues, and aesthetic concerns. Some of these problems include standing water, ice accumulation in the winter, wet soil, erosion, and sedimentation. The Stonehedge development was issued a temporary pollution (stormwater) permit from the State of Vermont Agency of Natural Resources (ANR) when it was constructed. However, this permit expired on July 1, 1985. In order for the City’s Stormwater Utility to consider taking ownership of the Stonehedge stormwater system, it will need to be brought into compliance under the ANR Engineering Feasibility Analysis (EFA), which attempts to comply with the State of Vermont ANR 2002 Stormwater Treatment Standards.”

In 2010, the City of South Burlington brought the Laurel Hill development, which was experiencing similar problems, into the study process, and commissioned a study to identify solutions to the stormwater problems in both neighborhoods. These neighborhoods are shown on the below project location map.

2. STONEHEDGE

The purpose of the borings within the Stonehedge development was to characterize soil materials, groundwater depths, and absence of shallow ledge at key locations where improvements were proposed. A total of 5 borings were performed: two in the location of the proposed stormwater pond and three along the proposed drainage pipe routes. Note that the drainage pipe proposed along SH4 and SH5 was abandoned during the design process due to its depth, disruption and serviceability.

The soils were characterized as sand with little silt overlaying clay at a depth of 16 feet.

3. LAUREL HILL

The purpose of the borings within the Laurel Hill Project was to characterize the soil type and depth of groundwater to support an in-ground stormwater infiltration system under Deborah Drive. Deborah Drive was chosen as it was free of other utilities and easily accessible form the existing stormwater piping network. The soils were found to be sand with suitable characteristics to support an infiltration system. However, the groundwater conditions were not. At the time (fall 2010) of the borings, groundwater was reported in the range of 2 to 5 feet below the surface. Several ground water monitoring wells were installed at that time. These wells were checked again in the summer (July 2011) and groundwater was found to be between 32 and 52 inches below the surface. It was therefore concluded that an inground stormwater infiltration system was not feasible.

Additional subsurface explorations were not necessary as the proposed pipeline will follow the alignment of the existing stormsewers at approximately the same depth. In addition the City Public Works Department reported that the soils within the project area are sands with no ledge encountered within the depth range proposed.
