As the third leg of the ‘Triple Bottom Line’, social equity, quality of life and community health are becoming an important component of the conversation surrounding Low Impact Development (LID). The question is, though, how can we investigate how LID affects those aspects of a community? This session is meant to be a primer for the various tools and information available to help do just that, including health impact assessments, health improvement plans, and health needs assessments. These tools are invaluable to give engineers, landscape architects and planners the actionable data they need to start addressing the specific health needs of a community in addition to the environmental needs.
In addition, this session will begin to help elevate the field of LID through case studies that will show how to integrate the analysis of community health, weigh the health impacts of the built environment and utilize best practices for planning and design for human health.

A variety of national, regional and local governing jurisdictions have required or strongly encouraged the use of traditional green infrastructure to management stormwater runoff and mitigate downstream flood impact. These Best Management Practices (BMPS) include such techniques as bioretention, rain gardens, permeable pavements, porous asphalt or concrete, bioswales and surface ponds. These methods can remove contaminants from the water, and attenuate or retain the stormwater runoff to allow for evaporation, transpiration or infiltration.
Traditional green infrastructure techniques have been well tested and proven to effectively mitigate stormwater. However, there are many challenges and long term costs associated with the means and methods of these BMPs. Furthermore, the long term cost of use has not been established in the region because the use of these practices are somewhat new. Especially in urban environments, where real estate is costly and limited, there has been a growing trend to utilize subsurface water quality and quantity techniques.
This discussion will overview the variety of subsurface BMPs used for stormwater management to reduce, reuse, eliminate and/or mitigate stormwater. It will discuss and demonstrate the effectiveness of utilizing a combination of green and grey infrastructure in design. I will also present the many advantages these techniques offer that greatly reduce the life cycle cost, through significantly reduced maintenance and replacement costs, as compared to traditional green infrastructure BMPs.

As the infrastructure of the mid-twentieth century reaches the end of its design life, municipalities are provided with the opportunity for another chance to reshape the urban landscape with different goals in mind. The City of Omaha (City) has taken this opportunity to heart with the rehabilitation of two urban stream channels (Hell Creek and Rockbrook Creek) that were lined with concrete in the 1960s. This concrete had deteriorated to the point of failure and instead of encasing the stream in new concrete, the City decided to seize the opportunity to stabilize the channel while creating a more functional aquatic ecosystem by using bio-engineering techniques.
This approach for low impact re-development has resulted in projects that not only provide a more natural appearance with native grasses on the banks and cascading rock structures in the channel, but also the streams provide better habitat for aquatic life in the deep pools and aerating riffles. The innovative use of bio-engineering techniques within these confined urban corridors achieved the multi-level project goals of improved ecosystem conditions, public safety, and flood management while also being eligible for over $1.6 million in environmentally focused grants.
