Description:

The project will develop and test methodology for watershed management in urban and urbanizing watersheds. Management is based on quantitative risk assessment of urbanization to the watershed ecosystem, including people residing in the watershed and affected by the receiving water body, and biota residing in receiving water bodies.

Objectives/Hypotheses:

The specific research objectives are: (1) Develop statistical flow, loading and water quality models applicable to risk assessment; (2) Develop objective and quantitative risk assessment procedures for estimating ecological risks of stormwater and subsurface discharges from urban and suburban watersheds; (3) Develop methodology for assessment of flood control and water quality benefits and resolve conflicts between flood control and ecological preservation-restoration objectives; (4) Develop benefits/cost models for urban watershed management to optimize both flood control and receiving water integrity; (5) Research innovative financing of urban watershed management, identify key players, and assess the willingness to pay for different types of benefits; and (6)Examine homeowners' risk/benefit perceptions, values, affective responses to the risk, subjective norms, socio-cultural backgrounds, and use of communication in the willingness to pay for these different types of benefits. The methodology will be developed and tested on two pilot watersheds in Milwaukee(WI) county.

Approach:

Research activities in this three-year project are divided into eight tasks: (1) Watershed - Water Body Assessment (chemical and physical integrity); (2) Development of stochastic (statistical) loading and water quality models; (3) Development of a methodology for qualitative and quantitative assessment of flood control and water quality benefits; (4) Development of objective and quantitative risk assessment procedures for estimating ecological risks of stormwater and subsurface discharges from urban and suburban (including urbanizing) land uses; (5) Urban stream restoration; (6) Development of benefits/cost models for urban watershed management; (7) Survey homeowners and citizens on benefit/risk perceptions; and (8) Synthesis.

Expected Results:

Presently, no ecological standards are available for urban drainage and water body restoration projects and most projects are driven by flood protection objectives, leading to conveyance oriented modification of the urban (suburban) water bodies. Conveyance solutions (such as channel lining and straightening) have adverse ecological consequence and, commonly, are economically inefficient. Today, such projects and solutions may not be acceptable. Incorporating ecological integrity objectives may lead to storage oriented approaches and restoration of ecological integrity of urban receiving water bodies.
