The New York City Department of Environmental Protection has the technology to fix the problem, and should collaborate with Yorktown to reduce stormwater to manageable levels.
Smaller sized raingardens affording the same level of stormwater treatment had the lowest overall impacts reinforcing the principle that using fewer resources reduces environmental impacts.
The aim of this paper is to present the performance and parameter sensitivity of stormwater models with different levels of complexities, using the formal Bayesian approach.
This paper presents a novel modeling analysis of a 40-year-long dataset to examine the impact of urbanization, with widespread stormwater infiltration, on groundwater levels and the water balance of a watershed.
These include models that show planners how much water a green roof at a given location is likely to capture, and GIS-based models that show how a larger-scale shift to green roofs would affect stormwater outflow at the watershed level.
Although the remaining geese at the Biltmore Avenue beach do not gather close enough to the shore to cause a problem, Mr. Jacobs said, stormwater runoff this year has driven coliform levels beyond acceptable state levels.
We demonstrated an analytic process of increasing model flexibility to determine hydrologic effectiveness of stormwater management at the sub-catchment level.
Communities Must Lead Whether developing bike shares, planting trees to help clean the air, developing parks and other green spaces that help cities manage stormwater, planning for changes in sea level or ensuring access to nature (indoor and out) to improve people's lives, small changes matter.
All sources of sediment showed some level of toxic potential with stormwater bed sediment the highest followed by stormwater suspended, street dirt, and streambed.
E. coli and Enterococcus sp. were measured in addition to molecular markers including Bacteroides Human-Specific Marker (HS) and fecal Bacteroides spp. Levels of FIB in stormwater far exceeded recreational water quality guidelines, frequently by several orders of magnitude.
