A bioswale integrating an engineered soil and trees was installed in a parking lot to evaluate its ability to reduce storm runoff, pollutant loading, and support tree growth. The adjacent control and treatment sites each received runoff from eight parking spaces and were identical except that there was no bioswale for the control site. A tree was planted at both sites. Storm runoff, pollutant loading, and tree growth were measured. There were 50 storm events with a total precipitation of 563.8… 
Tree Species Suitability to Bioswales and Impact on the Urban Water Budget.
It is concluded that species with high stomatal conductance and large mature form are likely to contribute best to bioswale function, thereby reducing runoff and discharge from the parking lot.

Performance of Two Bioswales on Urban Runoff Management
This study evaluated the effectiveness of two bioswales eight years after construction in Davis, California. The treatment bioswale measured 9 m × 1 m × 1 m (L × W × D). Engineered soil mix (75%
Influence of urban land development and subsequent soil rehabilitation on soil aggregates, carbon, and hydraulic conductivity.
Trees and Streets as Drivers of Urban Stormwater Nutrient Pollution.
It is demonstrated that vegetation near streets contributes substantially to stormwater nutrient pollution, and therefore to eutrophication of urban surface waters, through deposition of nutrient-rich leaf litter onto streets connected to storm drains.
The Influence of Urban Soil Rehabilitation on Soil Carbon Dynamics, Greenhouse Gas Emission, and Stormwater Mitigation
Global urbanization has resulted in rapidly increased urban land. Soils are the foundation that supports plant growth and human activities in urban areas. Furthermore, urban soils have potential to
Urban Trees as Green Infrastructure for Stormwater Mitigation and Use
Impervious surfaces in urban areas generate substantial volumes of polluted surface runoff, resulting in flooding and degradation of waterway ecosystems. Urban trees can help to mitigate the adverse


Toxicity of Parking Lot Runoff After Application of Simulated Rainfall
Simulated rainfall was applied to parking lots to examine the toxicity of runoff while controlling for antecedent period, intensity, and duration of rainfall, and dissolved zinc was most likely the primary cause of toxicity.
Low-Impact Parking Lot Design Reduces Runoff and Pollutant Loads
An innovative parking lot at the Florida Aquarium in Tampa, Fla., is being used as a research site and demonstration project to show how small alterations to parking lot designs can dramatically
A New Urban Tree Soil to Safely Increase Rooting Volumes Under Sidewalks
Soil compaction, which is necessary to safely support sidewalks and pavement, conflicts with urban trees' need for usable rooting space to support healthy tree growth. We have defined a rigid soil
Vegetative storm water controls include grassed swales and vegetated filter strips. The effectiveness of these controls for removing pollutants found in runoff from highways and other urban areas has
Transpiration and Root Development of Urban Trees in Structural Soil Stormwater Reservoirs
Evaluated tree water uptake and root distribution in a novel stormwater mitigation facility that integrates trees directly into detention reservoirs under pavement concludes this system is feasible and provides another tool to address runoff that integrates the function of urban green spaces with other urban needs.
Can urban tree roots improve infiltration through compacted subsoils for stormwater management?
Although high water tables may limit tree rooting depth, some species may be effective tools for increasing water infiltration and enhancing groundwater recharge in this and other I-BMPs (e.g., raingardens and bioswales).
Erratum: Testing of Structural Urban Tree Soil Materials for Use Under Pavement to Increase Street Tree Rooting Volumes
Quercus robur seedlings were grown in compacted stone-soil mixes known to meet engineering standards for pavement base compaction and strength. Root penetration into these materials was greatly
Field Evaluation of Permeable Pavement Systems for Improved Stormwater Management
Abstract The contribution of impervious surfaces to the disrupted runoff processes in an urban watershed is overwhelming. Nearly all the problems ultimately result from the loss of the
