EPA Launches 2015 Green Infrastructure Webcast Series

"Green Infrastructure and the Sustainable Communities Initiative"

A manual prepared by the Center for Watershed Protection

For the past two years, the AridLID Workshops held in Albuquerque, New Mexico have built a growing discussion and exposition of Green Infrastructure (GI) and Low Impact Development (LID) practices that are appropriate to the unique climates of the southwestern U.S. In 2012, we are holding the conference in Tucson, Arizona, with the twin goals of sharing best practices and building professional networks across a wider swath of the region, and of developing a clearer Southwestern vision and voice in the growing national discussion on GI/LID. We are now soliciting proposals for speakers and posters.

Accountability considerations are important in all actions involving permits or enforcement orders, regardless of the approaches used to achieve compliance with established standards. This factsheet discusses six accountability mechanisms that may be applied to permits or enforcement actions that include green infrastructure.

Green infrastructure can reduce the volume of stormwater entering combined sewer systems during precipitation events, which may reduce numbers and volumes of overflows. This factsheet addresses the evaluation of green infrastructure approaches for CSO control, the identification of quantitative implementation targets, and the incorporation of green infrastructure approaches into Long Term Control Plans.

Depending on the causes of SSOs for a particular system, green infrastructure approaches may be used in conjunction with grey infrastructure improvements and capacity, management, operations and maintenance (CMOM) to help eliminate SSOs. This factsheet discusses how green infrastructure approaches may be integrated into CMOM plans and CSO consent decrees.

Much of the aquatic ecosystem degradation associated with stormwater is caused by changes in discharge volumes, rates, and durations. This factsheet discusses how green infrastructure can be integrated into stormwater permits to maintain more natural flow regimes.

Many 303(d)-listed waters are impacted by changes in natural hydrology associated with urbanization. This factsheet describes how Total Maximum Daily Loads (TMDLs) and TMDL implementation plans (IPs) can address the hydrological factors that contribute to impairments by including green infrastructure.
