Stormwater Control Measures (SCMs) have been developed to mitigate the hydrologic and water quality impacts of urban areas and IC. This paired watershed study evaluated the impacts of SCM retrofits on hydrology for a small urban drainage area. In February 2012, a bioretention cell (BRC) street retrofit, four permeable pavement parking stalls and a tree filter device were installed to control and treat residential street runoff in Wilmington, North Carolina, USA. In the SCM-Retrofit catchment, 52% of the directly connected impervious area (DCIA) and 69% of the total drainage area was retrofitted for potential hydrologic mitigation. Underlying soils in the study area were urban sands. Peak discharge significantly decreased by 28%, while lag times in the catchment remained unchanged. Runoff depth significantly decreased by 52%. When compared to the control catchment, runoff depths in the SCM-Retrofit catchment were significantly less for events with low hourly rainfall intensities (<2.7 mm/h), but significantly greater for events with high intensities (>7.4 mm/h). During post-retrofit monitoring, runoff thresholds in the SCM-Retrofit and control catchments were 5.2 mm and 3.5 mm, respectively. The SCM-Retrofit runoff coefficient decreased from 0.38 to 0.18 and was substantially less than other runoff coefficients reported in the literature for conventional residential development. This study illustrated how a limited number of SCM retrofits installed within the public right-of-way can mitigate some of the hydrologic impacts of existing residential development.}, journal={JOURNAL OF HYDROLOGY}, author={Page, Jonathan L. and Winston, Ryan J. and Mayes, Dave B. and Perrin, Christy and Hunt, William F., III}, year={2015}, month={Aug}, pages={923–932} } @article{page_winston_hunt_2015, title={Soils beneath suspended pavements: An opportunity for stormwater control and treatment}, volume={82}, ISSN={["1872-6992"]}, DOI={10.1016/j.ecoleng.2015.04.060}, abstractNote={Trees provide air quality, water quality and aesthetic benefits to urban areas. However, urban soils are frequently compacted to meet the structural stability requirements of pavements and buildings. Suspended pavement systems create an uncompacted soil volume beneath pavements in built environments to provide suitable conditions for tree root growth and structural stability for pavements. Another potential use of the soil–root matrix beneath a suspended pavement includes stormwater management. Two suspended pavement systems were constructed in Wilmington, North Carolina, USA, and runoff was routed through the root–soil matrix for detention and treatment. The two retrofits each contained 21.2 m3 of soil volume with a crape myrtle (Lagerstroemia indica x fauriei) and were nearly identical. An impermeable geomembrane isolated the water quality impacts of the system and an internal water storage (IWS) layer promoted NO2,3-N removal through denitrification. At one retrofit, 80% of runoff over the yearlong monitoring period was treated. For storms that did not generate bypass, significant mitigation of peak discharge (QP) was observed (62%). Pollutant concentrations of TKN, NO2,3-N, TAN, TN, O-PO43−, TP, TSS, Cu, Pb and Zn all decreased significantly at both retrofit sites. Effluent NO2,3-N concentrations between the retrofit sites were not significantly different despite varying organic matter content and a substantial difference in influent NO2,3-N concentrations. Effluent concentrations of TSS, Cu, and Zn were not statistically different between the sites, indicating consistent treatment of particulate and particulate-bound pollutants within the systems. This proof-of-concept study illustrates that the soil–root matrix beneath a suspended pavement system can be used as a stormwater control measure (SCM) to concomitantly achieve water quality, pavement stability and urban forestry goals.}, journal={ECOLOGICAL ENGINEERING}, author={Page, Jonathan L. and Winston, Ryan J. and Hunt, William F., III}, year={2015}, month={Sep}, pages={40–48} }
