EII Phase I (2006) Watersheds Report
(City of Austin Watershed Protection Department, 2007) Clamann, Andrew
Environmental Integrity Index (EII) Phase I data collected during 2006 are presented and reviewed. Sixteen of the 46 watersheds throughout the greater Austin area were analyzed to assess environmental conditions. These values are in use as part of the Citywide WPDRD masterplan in prioritizing subwatersheds to address through Capital Improvement Projects, regulations and/or programs. The values are also used in the WPDRD Business Plan as performance measures for water quality maintenance.
Environmental Integrity Index Phase 1 (2003) Watersheds Report
(City of Austin Watershed Protection and Development Review Department, 2006) Clamann, Andrew; Harrison, Jeremy
Environmental Integrity Index (EII) data collected during Phase I of the Citywide Watershed Protection Department Masterplan are presented and reviewed by watershed in this report. Sixteen of the 46 watersheds throughout the greater Austin area were analyzed to assess environmental conditions. These values are in use as part of the Citywide WPDRD masterplan in prioritizing subwatersheds to address through Capital Improvement Projects, regulations and/or programs. The values are also in use in the WPDRD Business Plan as performance measures for water quality maintenance.
Environmental Integrity Index Phase I & II (2009-2010) Watershed Summary Report
(City of Austin Watershed Protection Department, 2011) Clamann, Andrew
Environmental Integrity Index (EII) Phase I & II data collected during 2009 and 2010 are presented and evaluated within the context of historical EII data. Forty-nine watersheds throughout the greater Austin area were sampled to assess environmental conditions. These values are in use as part of the Citywide WPDRD masterplan in prioritizing subwatersheds to address through Capital Improvement Projects, regulations and/or other programs. The values are also used in the WPD Business Plan as performance measures for water quality maintenance.
Environmental Integrity Index Phase I & II (2013-2014) Watershed Summary Report
(City of Austin Watershed Protection Department, 2015) Clamann, Andrew; Jackson, Todd; Clayton, Rob; Richter, Aaron
Environmental Integrity Index (EII) Phase I & II data collected during 2013 and 2014 are presented and evaluated within the context of historical EII data. 118 sites located within 50 watersheds throughout the greater Austin area were sampled to assess environmental conditions. This data is primarily used for prioritizing subwatersheds for Capital Improvement Projects, regulations and/or other programs through the Citywide Watershed Protection Department masterplan. The values are also used in the WPD Business Plan as performance measures for water quality maintenance. The baseline information accumulated through the EII provides a large, comprehensive and quality assured dataset unique to our region which can be utilized for identifying and tracking both anthropogenic and climatic changes to our aquatic resources.
Linking BMPs to Receiving Water Impact Mitigation in Austin, TX
(City of Austin Watershed Protection and Development Review Department, 2005) Turner, Martha; Herrington, Chris
Changes to receiving water bodies following Best Management Practices project (BMP) implementation were evaluated using the Environmental Integrity Index (EII). Data from five wet ponds and one channel restoration project were used. Changes in the six EII sub-indices (water quality, sediment quality, contact recreation, non-contact recreation, habitat quality and aquatic life support) were generally positive except for habitat quality, which declined initially but tended to recover. Water quality through wet pond sites improved by an average of 7%, and the channel erosion site improved water by 18%. Additional data collection is needed to strengthen conclusions.
