Street sweeping has long been recognized as an effective best management practice (BMP), one that can reduce the amount of stormwater pollutants entering storm conveyance systems and receiving waters. Comprehensive studies led by Dr. Sansalone at the University of Florida, conducted in association with fourteen Florida MS4s and the Florida Stormw...

Cross Israel Highway Stormwater Quality Study FINAL REPORT This document presents the final results of an extensive study of the stormwater quality from a 2.4 kilometer segment of Section 13 of the Cross Israel Highway (CIH), called for the purposes of this report, the Rosh Ha’ayin segment. In the spring of 2000, several parties raised a concern t...

The authors have been involved in numerous street cleaning research projects for over 30 years. This paper will give us a unique opportunity to highlight the historical use of street cleaning as a method for reducing stormwater pollutants, and will examine newly emerging street cleaning technologies. There have been many misconceptions concerning t...

A load estimation procedure for the urban pollutant loadings and estimating optimum cleaning practices for streets and catch basins by Simlified Particulate Transport Model (SIMPTM) is discussed. The procedure of estimating sediment particles (street dirt) involves monitoring sediments that are representatives of the watershed's various land uses....

The U.S. Environmental Protection Agency's (USEPA) Stormwater Management Model, or SWMM, is a large, relatively complex software package capable of simulating the transformation of precipitation to urban runoff and the transport of the runoff from the ground surface through pipe/channel networks and storage/treatment facilities and finally to recei...

This paper will outline the study design and describe the results of two separate studies that used this approach to quantify pollutant loadings and optimize load reductions for two Michigan watersheds. The first study was conducted in association with Hubbell Roth and Clark, Inc. (HRC) for the City of Livonia's portion of the Bell Branch and Tarab...

It has been estimated that within the next ten years Total Maximum Daily Load (TMDL) analyses will be required on over 20,000 water quality impaired waterways throughout the United States. The great majority of these waterways are receiving significant amounts of pollutants from urban and urbanizing landscapes via stormwater. One of the greatest te...

Research work completed in the mid-1990's suggests that street sweeping programs can be optimized to reduce the pollutant washoff from urban streets significantly. The abilities of several different sweeping technologies to pick up accumulated street dirt at various sites were evaluated. In addition, the expected reductions in average annual washof...

Annual runoffs and pollutant loads for six homogeneous Nationwide Pollutant Discharge Elimination System (NPDES) storm water sites in Portland, Oregon, were simulated using SIMPTM, the Simplified Particulate Transport Model, calibrated to local runoff quality data. Results clearly showed that current linear or exponential sediment accumulation mode...
