Geomorphic
and Habitat Assessments,
River
Corridor Planning
Fitzgerald
Environmental
Associates (FEA), under contract to the Windham County Natural
Resources Conservation District, carried out Phases 1, 2, and 3
geomorphic assessments and developed a River Corridor Plan following
the VTANR protocols. Phase 2 data collected by FEA along the main stem
and tributary reaches formed the basis for Fluvial Erosion Hazard (FEH)
planning in towns affected by past flooding and streambank erosion.
FEA
and a partnering consulting firm were selected to carry out the first
large-scale project using the VTANR geomorphic assessment protocols in
the state of New Hampshire. The project encompassed 60 river miles
within the Exeter River watershed, one of 15 rivers designated for
increased protection within the state. The effort culminated with the
development of a watershed restoration plan of the entire basin.
Under
contract to the Two Rivers-Ottauquechee Regional Commission and the
Town of Sharon White River Task Force, FEA carried out Phase 2
geomorphic assessments and developed a River Corridor Plan of the White
River and its tributaries within the Town of Sharon. The study covered
15 river reaches (30 segments), FEA utilized the new VTANR Rapid
Habitat Assessment Protocols (RHA) and Culvert Screening Tools to
identify and prioritize restoration projects for the watershed's
salmonid fishery.

River Restoration Design Rock River Tributary - Highgate, VT FEA, in conjunction with several partnering firms, carried out an alternatives analysis to evaluate stream restoration approaches for a small tributary to the Rock River that was impacted by agricultural land use. The design process included detailed site surveys, hydrologic and hydraulic modeling to determine the frequency and magnitude of channel flooding, and water quality analysis to predict reductions in downstream pollutant loading following restoration. |

Saxtons River Dam Removal for AOP Restoration - Grafton, VT As part of the Saxtons River Corridor Plan, FEA completed a preliminary feasibility study for the lowest reach on the South Branch of the Saxtons River in Grafton, VT. A breached concrete dam has historically caused debris jams, resulting in decreased aquatic organism passage (AOP) and channel instability. FEA completed a detailed channel survey to understand potential adjustments of the channel bed following structure removal, and developed cost estimates for final design, permitting, and implementation. |

Stormwater Management Shelburne Farms Stormwater -
Northwestern VT FEA assissted Ecosolutions,
LLC
, in development of
an ecologic stormwater design for the dairy
farm on the Shelburne Farms property. FEA developed a runoff
analysis
for the site and is worked with Ecosolutions, UVM, and Shelburne
Farms stakeholders to understand the site's pollutant loads and develop
a final the design to mitigate the farms impacts to downstream water
quality. The design incorporated Low Impact Design
principles and other innovative solutions for treating nutrients from
the
farm site.
Farrell Park Demonstration Project - Northwestern VT FEA worked
with Ecosolutions,
LLC
on a demonstration project for an innovative stormwater design at
Farrell
Park in South Burlington, Vermont. Funded by the Winooski
Natural
Resources Conservation District, the design incorporated a series of
sedimentation chambers with a gravel
wetland cell to treat sediment-laden runoff flowing into Potash
Brook.

- Essex, VT FEA
worked with the Essex High School Environmental Club and Ecosolutions,
LLC, to help mitigate stormwater impacts of the faculty parking lot.
FEA helped the Environmental Club acquire grant funding, designed and
oversaw the construction of the structure and plantings.

Geographic Information Systems (GIS) and Modeling
The VTANR Center and Clear Program funded a pilot project with a large dairy farm in Franklin County to improve the permitting process for converting fallow lands into cropland. FEA, in conjunction with several partnering consultants, developed a geospatial model to determine the suitability of land for cropland conversion. The model output includes potential field scores and ranks based on: 1) natural resource constraints such as wetlands and proximity to impaired waterways, and 2) land productivity considerations such as crop yield and field slope. |
