Wetland mapping and surveying services

Organization: 
North Haven Trail Association
Date Issued: 
Amount: 
1 500.00
Description: 
To support wetland mapping and surveying services which are critical components to acquiring easements from private property owners along the proposed trail route on the eastern banks of the Quinnipiac River in North Haven.

The maps were used in work regarding the location and definition of legal easements. It was also used by town agencies in the development of revised zoning regulations for the enhanced protection of the Quinnipiac River when new developments are proposed along its banks.

Assess the condition of macrofaunal communities in New Haven Harbor

Organization: 
University of New Haven, Dept. of Biology and Environmental Science
Date Issued: 
Amount: 
11 900.00
Description: 
To support the assessment of the condition of macrofaunal communities in New Haven Harbor relative to selected environmental factors and the structure of the Harbor's benthic habitats. A comparison of the results will be made to available previous information to assess any long-term changes.

Biodiversity and Impacts of Drift Algae in New Haven Harbor study

Organization: 
University of New Haven, Dept. of Biology and Environmental Science
Date Issued: 
Amount: 
10 000.00
Description: 
To support the Biodiversity and Impacts of Drift Algae in the New Haven Harbor study, which will continue to assess habitat structure and species diversity in New Haven Harbor, and to investigate the dynamics and potential impacts of extensive drift algal mats that have been found in portions of the harbor.

Field Research Program

Organization: 
Yale University Grant and Contract Administration
Date Issued: 
Amount: 
14 350.00
Description: 
To support Field Research Program to document wetland loss along the Quinnipiac River Estuary and document baseline conditions and historic trends.

In the 115-acre marsh area studied, 42 acres were converted from marsh vegetation into mudflat between 1974 and 2000 at an average loss rate of 1.6 acres per year, indicating that mudflat currently occupies approximately 36% of the site.

The Quinnipiac River Watershed and Region Geographic Information System

Organization: 
University of New Haven, Dept. of Biology and Environmental Science
Date Issued: 
Amount: 
15 050.00
Description: 
To develop GIS data layers of selected brownfield sites in Hamden, CT, and develop and analyze detailed GIS data layers for the marshes in the lower Quinnipiac River.

A GIS of the lower Quinnipiac River marsh was developed. It included data layers of building footprints, elevations and land cover; surface inventories; and assessments of flood zones and potential runoff effects on the marsh. The vegetation map illustrated that the reed Phragmites australis dominated the marsh.

Municipal Land Use Regulations

Organization: 
Yale University Grant and Contract Administration
Date Issued: 
Amount: 
15 000.00
Description: 
To collect and  publish a systematic review of municipal land-use regulations in the Quinnipiac River Watershed.

Of the 16 facilities discharging into the river under the NPDES permit program, there were relatively few permit violations. However, easy access to permit discharge information prevents public knowledge about pollutants in the river and enroucages the status quo rather than the lowering of pullutant concentrations.

Web Page Development/GIS data & QRW data

Organization: 
University of New Haven
Date Issued: 
Amount: 
13 000.00
Description: 
Continued support for the development of a geographic information system for the Quinnipiac River watershed.

Geographical Information System Database

Organization: 
University of New Haven, Dept. of Biology and Environmental Science
Date Issued: 
Amount: 
11 000.00
Description: 
To develop a geographical information system database for the Quinnipiac River Watershed.

The overall objective of this specific portion of the project was to develop aerial photographic coverage for the entire QRW and key sections of other watersheds which drain into New Haven Harbor. The aerial photographic coverage can be used for a variety of applications. Users of the GIS can "fill in the gaps" by visual inspection with respect to particular problems. By having aerial photography available as a data coverage in the GIS, a planner or researcher could display the photo and compare it to more general information and assess such relationships.

3 Hydrographic Dye Dilution Studies

Organization: 
CT Dept. of Agriculture/Aquaculture Division
Date Issued: 
Amount: 
7 000.00
Description: 
Complete three hydrographic dye dilution studies of the Wastewater Pollution Control Facilities.

Added dye to water from local Wastewater Pollution control facilities and studied how water and sewage moved into shellfish growing areas. Readings found to be consistent with typical sea water studies (higher flow after rain storm), though one area had higher flow than other two, and one shellfish breeding area was raised from "restricted" to "conditionally approved."

Evaluate Road Salt Management & Applications

Organization: 
New Haven County Soil & Water Conservation Di
Date Issued: 
Amount: 
5 000.00
Description: 
To evaluate road salt management and application practices; correlate problems and recommend future action.

Evaluated locations of salt storage and storage practices. Assessed dangers of runoff and contamination sites pose to water systems in area, and found danger to be considerable. More research into private contractors suggested.
