Urban Construction Site Runoff Diorama
Monroe County Soil and Water Conservation District
Basin Program Funds:
Urban sprawl-type development in the suburbs of the city of Rochester is increasing
stormwater runoff and associated pollutant loadings to the tributaries that
lead to Lake Ontario. The results are stressed creek channels, stressed aquatic
habitats and increased pollutant loading to Lake Ontario.
The goal of the Urban Construction Site Stormwater Runoff Diorama is to foster
a better understanding of the negative impacts of urban stormwater runoff on
the Great Lakes water quality by building a three-dimensional display (diorama)
that depicts how stormwater runoff from construction sites and storm sewers
ends up in a stream.
Suburban growth in Monroe County around the city of Rochester is causing high
volumes of stormwater runoff and pollutant loadings. The runoff enters, and
impacts, Lake Ontario, the major source of Monroe's potable water supply and
the focal point of recreation dollars for the community's tourist industry.
The diorama will provide a visual demonstration of the effects of urban stormwater
runoff on a waterbody in an effort to improve the general public's and local
officials' awareness and understanding of the nonpoint source pollution problem.
If local decision makers are made aware of the need to invest time and money
to long-term stormwater management and construction site erosion and sediment
controls, the area's water quality could be greatly improved.
The Monroe County Soil and Water Conservation District, in consultation with
the Monroe County Department of Health, the Rochester Institute of Technology,
and a professional model-making firm, designed and constructed a 3-D model depicting
sediment movements from construction sites, effects of properly engineered practices
to control erosion, where storm sewers exist, and riparian land impacts. A backdrop
depicting (by photos and text) actual good and bad practices
from construction sites around the country is also displayed.
The diorama has been presented/displayed at the Conservation District's Western
New York Stormwater Management Conference and trade show (180 people), the Conservation
District Annual Banquet meeting (100 people), the Livingston County Fair (500
people), and the Pittsford Harvest Festival (1000 people). The diorama is planned
for use in many future educational workshops.
