Review of the Edwards Aquifer Habitat Conservation Plan: Report 2 (2016)

Responding to advice provided in a 2015 report from the National Academies, the Edwards Aquifer Authority has made several improvements to its 15-year Habitat Conservation Plan, the goal of which is to protect endangered species while supporting water needs in the region. This new report finds that good progress has been made in ecological modeling, in biological and water quality monitoring, and in implementation of the plan’s minimization an... More >>

Progress Toward Restoring the Everglades: The Sixth Biennial Review, 2016 (2016)

Sixteen years into the Comprehensive Everglades Restoration Program, several project components are completed or nearing completion and are beginning to yield measurable results, especially in terms of creating hydrologic conditions increasingly similar to pre-drainage flows. This sixth biennial review of the $16.4 billion CERP project finds that, although measurable progress is being made, there is insufficient attention on radically changin... More >>

Evaluation of the Predictive Ecological Model for the Edwards Aquifer Habitat Conservation Plan: An Interim Report as Part of Phase 2 (2016)

The Edwards Aquifer is the primary source of water for drinking in the San Antonio area, and supplies the two largest freshwater springs in Texas, Comal Springs and San Marcos Springs. Both spring systems are used for recreation and are home to several species of fish, amphibians, insects, and plants found nowhere else. Eight Edwards Aquifer species are on the federal Endangered Species List because they are vulnerable to reduced spring flow... More >>

Using Graywater and Stormwater to Enhance Local Water Supplies: An Assessment of Risks, Costs, and Benefits (2015)

Graywater and stormwater capture and use can expand local water availability while providing additional benefits, such as reduced water pollution (for stormwater) and a drought-resistant year-round water supply (for graywater). Treatment can help address contaminants in the water, but a lack of risk-based treatment guidelines hinders the broader use of stormwater and graywater, this report finds. There is no single best way to use graywater o... More >>

Affordability of National Flood Insurance Program Premiums: Report 2 (2015)

Drawing on lessons learned from a proof-of-concept analysis, this report proposes that the Federal Emergency Management Agency develop a microsimulation model--which will use a database of records for individual policyholders and property owners to mimic how policy decisions might affect those individuals--to simulate the effects of different National Flood Insurance Program affordability policy options. The report also notes, however, that som... More >>
