Citywide program to enhance resilience to flood, drought, and other stormwater-related hazards on private property for owners and renters through incentives and programs. Solutions specific to WPD/stormwater resilience could include rainwater harvesting, rain gardens, tree plantings, floodproofing, and other solutions. Question for CDS- can improvements be on private property (may need legal review) NEEDS ASSESSMENT FOR 2026 BOND FUNDING Project Name Project Type Dist. Estimate Requestor Scope/Description Land Acquisition City- wide 50,000,000 Multiple Departments – Land Acquisition 208 Balcones Canyon- land Preserve 2026 Land Acquisition Fund The Balcones Canyonlands Preserve (BCP) is a 32,000- acre system of preserves that exists as a multi-agency conservation effort operating under a regional 10(a) permit issued under the Endangered Species Act by the U.S. Fish & Wildlife Service. The permit was issued jointly to the BCP's two managing partners, the City of Austin and Travis County, in 1996. Several other partnering organizations own and manage land dedicated to the BCP. The BCP provides an umbrella of protection for two migratory songbird species, six cave-dwelling invertebrate species, and 27 additional species of concern. By protecting the most vulnerable species, the preserve safeguards the entire ecosystem. In addition to existing as a habitat for endangered species, these lands provide habitat for numerous native plants and animals and contribute to improved air and water quality and quality of life for the people of Austin. The majority of City BCP lands were acquired in the early 1990s through two bond propositions totaling $42M. Further funding would be used NEEDS ASSESSMENT FOR 2026 BOND FUNDING Project Name Project Type Dist. Estimate Requestor Scope/Description Land Acquisition City- wide 100,000,000 Multiple Departments – Land Acquisition 209 Water Quality Protection 2026 Land Acquisition Fund In 1998, Austinites voted to purchase land and conservation easements to protect the water quality and quantity in the Barton Springs segment of the Edwards Aquifer, creating the Water Quality Protection Lands (WQPL) program. The Barton Springs segment stores and moves water from just north of Kyle, north to its major discharge, Barton Springs, located in the heart of Austin. The WQPL safeguards groundwater that emerges at Barton Springs through the conservation and restoration of large, connected natural areas. Voters have continued to support the WQPL, approving several more bonds to purchase land to protect water, totaling over $235M. Currently, the WQPL program includes more than 34,000 acres of lands protected through fee simple ownership and City-held conservation easements. The City has nearly exhausted $72M in open space funding authorized in 2018, and significant opportunities still exist to meet the target of protecting 100,000 acres in the Barton Springs Zone. AWP MISSION DESCRIPTIONS Creek Flood: Projects or programs to address flood risk associated with major creeks and their tributaries.
