Stormwater Management Practices

Potential impacts of road salting on the environment have increased by the introduction of certain stormwater management practices. Specific impacts are discussed for four such practices, infiltration facilities, oil and grit separators, stormwater ponds and constructed wetlands. The main concerns about the hazards of chloride-laden stormwater discharges include contamination of groundwater, leaching out of trace metals, densimetric stratification and poor vertical mixing in ponds, direct and indirect toxic effects, benthic drift and reduced biodiversity. The associated environmental risks need to be reduced by chloride source controls, and prevention of excessive chloride accumulations by appropriate design and operation of stormwater facilities in winter months.

Stormwater Management Practices

Increasingly extended and alternative methods for urban stormwater management have been discussed in Germany and elsewhere. Without question an economically and ecologically sound combination of central and decentral measures will be a concept of the future. Yet, at present the introduction of approaches other than traditional combined sewer systems is restricted due to missing planning tools and technologies. Adding a number of frequently used Best Stormwater Management Practices (BSMP's) has widely extended the applicability of an existing stormwater water balance and pollution load model.

Specific Barriers

This study explores factors affecting adoption of two stormwater management practices, rain gardens and rain barrels. Mail survey data from Columbia, Missouri indicate adoption rates of 3.12 percent (rain gardens) and 7.47 percent (rain barrels). This unique dataset enables us to distinguish among nonadopters using knowledge levels, and to investigate the effect of practice-specific barriers. Clustered multinomial logistic regressions reveal serious gardeners are more likely to adopt both practices. Specific barriers differ by practice and type of nonadopter. Adding practice-specific barriers increased pseudo R2 values from 0.12 to 0.22 for rain gardens and from 0.13 to 0.26 for rain barrels.

Stormwater Management Practices

This study explores one of the least studied but most widely used instruments to control stormwater runoff — retention ponds. It is surprising that so little research within the economics literature has examined the efficacy of stormwater retention ponds. We address this gap in the literature by (1) offering a brief review of the existing literature; (2) discussing the nature of retention ponds as an impure public good; (3) extending a theoretical model to explain how stormwater runoff is currently managed; and (4) offering illustrative examples of governmental stormwater management practices in the coastal region of South Carolina. We posit that the current regulatory environment leads to a less than socially optimal level of management including a general lack of compliance enforcement and a misunderstanding of resource ownership. If sea levels continue to rise due to global climate change, then the mismanagement of stormwater runoff can lead to potentially severe adverse effects within coastal watersheds and estuarine ecosystems. We propose a combination of subsidy schemes and more-stringent enforcement actions to invoke a socially optimal provision of stormwater management services.
