March 3, 2020 ZAP Q & A Report B 3 Zoning: C14-2019-0129 - 10801 Wayne Riddell Loop; District 5 Question: Commissioner King Given its proximity to Slaughter Creek, does this case involve any environmental issues that should or must be reviewed by the Environmental Commission prior to review by ZAP? Answer: Staff A drainage study, an environmental assessment and a tree survey are not required for standard (non- PUD) zoning cases. These items will be submitted at the time a subdivision or site plan application is filed with the City and greater detail about the proposed development is required. B 7 Site Plan: SP-2019-0108D - Thaxton Road Tract Offsite Wastewater Improvements; District 2 Question: Commissioner Aguirre Answer: Staff (in Bold) Question 1: Please provide a breakdown of new wastewater lines (since 2013) that are located in creeks and CWQZs. Please provide a list of their locations and a map indicating where these are located. Response 1 Austin Water (AW) staff have verified with Austin Watershed Protection Department staff that there have been no variances requested or granted for construction of wastewater lines in the inner half of any critical water quality zone (CWQZ) since the establishment of current environmental criteria prohibiting construction of utility lines parallel and within the inner half of the CWQZ in 2013. Per current code, a utility line may be located parallel to and within the CWQZ if 1) in an urban watershed and not less than 50-ft from the centerline of a waterway, or 2) in a watershed other than urban and located not less than 50-ft from the centerline of a minor waterway, 100-ft from centerline of an intermediate waterway, and 150-ft from the centerline of a major waterway. Please note that this project is in a suburban watershed and the CWQZ is a 300-ft buffer from the centerline. The majority of the line is located in the outer 150-ft of the CWQZ which is allowed by code. The two relatively small encroachments into the inner half of the CWQZ comprise 860-ft of the 10,200-ft project scope for the oversized regional interceptor. One section will be bored and the other section will replace an existing smaller wastewater main that was constructed within the inner half of the CWQZ in 2015 (no variance required due to grandfathering). Question 2: Considering the Bull Creek sewage leakage incident, which was reported this past Sunday (Dec. 1, 2019), what can go wrong when placing interceptors along creeks and within CWQZs? Environmentally? Public Health? Response 2: An effective and efficient centralized wastewater collection, conveyance and treatment system, such as Austin’s wastewater system, is imperative to the overall health and vitality of our community. Unfortunately sanitary sewer overflows cannot be completely avoided. AW has a number of programs aimed at continued reinvestment and rehabilitation of wastewater conveyance infrastructure. Additionally, AW has various ongoing programs to prevent sanitary sewer overflows, reduce the risks of untreated wastewater entering the environment and emergency response activities associated with SSOs. That said, the public health and environmental impacts of sewage leaks can vary quite extensively depending on their location, the physical terrain, topography, cause of the spill, volume of the spill and other factors. Often times, sanitary sewer overflows are contained at point or origin and can be contained prior to entering neighboring creeks or streams. In all instances, AW staff are dispatched to restore service in the line and clean-up any wastewater overflow and related debris and remediate the area around the leak. Sanitary sewer overflows that are larger in volume can flow to nearby creeks or streams and, in some circumstances, have serious environmental impacts up to and including killing fish or other aquatic life in the receiving water. In these instances, a variety of environmental remediation techniques are employed to help reduce or mitigate the environmental impacts of the spill. Question 3: How many sewage leakage incidents have occurred in the past? What has been the cost to the city's taxpayers to clean up after such incidents have occurred. Response 3: The number, frequency, volume and impact of sanitary sewer overflows varies from year to year. In 2018 we experienced a total of 69 (24 hour reportable) sanitary sewer overflows (SSO). These SSOs ranged in estimated volume and causes including: grease blockages, debris, broken pipe, contractor, lift station, force main, deterioration, roots, vandalism, unknown and others. Individual estimated spill volumes ranged from 10 gallons to over 600,000 gallons. Austin Water spends significant amounts of money annually to maintain and improve the community's wastewater system. In 2018, AW spent approximately $12.9 million on wastewater system operations and maintenance activities. Similarly, during 2018, AW spent over $29 million related to capital improvements on wastewater conveyance system improvements and rehabilitation. In the early 2000s, Austin Water spent approximately $400 million on wastewater conveyance system capital improvements and rehabilitation as part of the Austin Clean Water program. (see attached Eastside Environmental News article) Question 4: McKinney Falls State Park is located not far downstream of this location. Who will pay the cost of cleaning up a sewage leakage in a State Park? Response 4: Regardless of the location of a sewage leak, Austin Water is responsible for costs of cleaning up sanitary sewer overflows as described in Response 2 above. In certain limited cases resulting from vandalism or sanitary sewer overflows caused by third party contractors, and where those other responsible parties can be identified, the City may impose fines, fees or pursue legal action for cleanup costs. However, these are extremely rare circumstances. Eastside Environmental News A City of Austin Newsletter from the East Austin Environmental Initiative A City of Austin Newsletter from the East Austin Environmental Initiative m ay 2 010 i s s u e 1 Austin Clean Water Program Helps Keep Creeks Cleaner T hanks to the tremendous ef- fort of the Austin Clean Water Program, creeks in Austin are now cleaner and healthier. Nearly eight years ago, the City began this program to fix the City’s sanitary sewer system and to reduce sewage overflows that were affect- ing creeks and waterways. The City faced heavy fines from the U.S. En- vironmental Protection Agency (EPA) if it did not complete the project by June of 2009. However, the program was complet- ed by the spring, ahead of schedule, and EPA ended its enforcement ac- tion against the City. The $400 million program involved 100 separate projects in 70 neigh- borhoods. This included replacing or repairing nearly 200 miles of pipe; eliminating 10 sewage lift stations; rerouting miles of sewer pipes away from streams; restoring stream banks; and improving response time to calls about sewer emergencies. Crews digging trench for new wastewater line. As a result of this program, there has been a dramatic drop in the volume and number of sewage overflows. In fact, recent testing shows that water quality has improved in at least a dozen of Austin’s creeks. The City’s test- ing involved two types of tests. One test uses several criteria to produce an environmental score that represents a “big-picture” water quality result. The second test is for ammonia, which can be an indicator of the presence of hu- man sewage. In addition, these test results indicate that water quality im- provements were most significant in East Austin creeks such as, Fort Branch above Manor Road, Tannehill Creek at Lovell Drive, Buttermilk Creek at Little Walnut Creek and Little Walnut Creek at U.S. 183. Last year, this program was voted one of the top 10 infrastructure projects in North America in the last 75 years by The International Right of Way As- sociation. The selection was based on projects that have had the “greatest impact on the American quality of life”. 24 Hour Pollution Hotline 974-2550 24 Hour Pollution Hotline 974-2550 Linea de la contaminación, atiende 24 horas al día Linea de la contaminación, atiende 24 horas al día Field Notes… GREEN, GREEN, GREEN. Unless you’ve been hiding under a rock lately, you know that GREEN is the color to be. Green is everywhere. Green cities, green houses, Oscar Garza green cars, even green festivals. But what does it all mean? It means that you want to live your life in an environmentally responsible and resource-efficient manner. It in- volves everything we do, from using renewable energy resources to the support of environmentally friendly products as opposed to those that pollute or harm the environment. The City of Austin is one of the leaders in the nation in this ef- fort. To help keep East Austin fully informed and prepared to meet the Green Challenge, we have expand- ed the Initiative’s outreach goals to include conservation efforts. This goal has been endorsed by the City Council and the Initiative will be putting our efforts into this en- deavor. In our latest newsletter, you’ll find articles about how we can all do our part to join in the green move- ment. Read how your community can become a “Green Neighbor- hood”. You may think about how to put your best green effort forward by recycling your household trash to make East Austin a better place. Also, see how Austin Brownfields’ Revitalization Office continues to work with the East Austin com- munity to transform brownfields - underutilized or polluted properties - into new, green, neighborhoods and businesses.

Absolutely everything! Austin Youth river Watch Program expands By Jacob Daniel Apodaca Recently, the Austin Youth River Watch Program (AYR- WP) expanded its capacity to reach more students in the Austin Independent School District. Recycling is about the easiest thing anyone can do to help keep our environment clean. Here in Austin, it’s so easy because you simply put all your recyclables in the big blue carts the City has provided you. That’s it! You don’t have to separate any recyclable materials or worry about what bin to put them in. And you can feel good that you’ve done your part to reduce pollution and improve air and water quality, save precious natural re- sources for your kids and for future generations. Amaz- ing what you can do with one simple act. What should you recycle? • Paper/cardboard, including newspapers, maga- zines, cereal and other food boxes • Plastic containers for milk, juice and sodas • Glass jars and bottles of all colors • Aluminum and steel cans such as soda and veg- etable cans Don’t put any food, plastic bags or Styrofoam in the blue carts. Plastic bags can be recycled by placing in des- ignated bins at your local grocery store. It’s important to dispose of all trash properly because no one wants to see plastic grocery bags blowing in the wind, broken glass in our parks, or plastic bottles floating where we swim. Cleaning up litter costs everyone. The City of Austin has provided you with a FREE blue cart for recycling, but you do have to pay for your regular trash cart. Now, here’s a little secret. When you go grocery shopping, pay attention and buy groceries in containers that can be recycled or reused. The more you recycle in the blue cart the less trash you put in your regular cart. Since you have less trash to throw away, you can exchange your bigger regular trash cart for a smaller cart…and pay less. Just call 311 if you want to exchange for a smaller cart. So now you know, recycling is easy, helps the environ- ment, keeps your neighborhood clean, and it can put a few extra coins in your pocket.

The program’s mission is to promote community-based envi- ronmental monitoring, awareness, and education while inspiring and advancing personal and scholastic achieve- ment. On a typical day, students meet after school to test wa- ter quality on Austin’s creeks or on the Colorado River. The data is submitted to the Colorado River Watch Net- work. They also conduct macroinvertebrate (very small spineless organisms) assessments and stream surveys. Newer students to the program learn the testing proce- dures from the more experienced students and from the program coordinators. After conducting the water qual- ity tests and field observations, they do their homework at the program’s center, assisting each other or receiving tutoring from interns and volunteers. They are also pro- vided with opportunities to learn about environmental careers and keep personal journals. Students go on camping trips at least twice each semes- ter. At least one of the camp-outs each year revolves around a study during which students conduct water quality tests every hour for 24 hours. This hands-on experience illustrates daily cycles in water quality. eAsTside envirOnmenTAl neWs River Watch participants are offered numerous traveling experiences to places like Russia, Wisconsin, Washington D.C., Big Bend National Park and many state parks in Texas. The students’ field trips emphasize environmental career paths and are designed to expand students’ hori- zons, and provide a better understanding of physical and cultural geography, ecology and natural processes.

Volunteers from the neighborhood, ABRO, City of Austin Solid Waste Services, University of Texas Center for Sustainable Development, School of Architecture, Austin Community Design and Development Center, and the Guadalupe Neighborhood Development Corporation cleared tons of debris from an East Austin brownfield site. Another east Austin Brownfield Gone Green! -Marilyn E. Jones Tires, wood scraps and other debris riddled the 11-acre property off Tillery and Goodwin Streets in East Austin. Recently, about five tons of household material and 244 tires were removed from this 11-acre brownfields property. Brownfields are properties that are idle due to their past use and unknown environmental history. The Tillery-Goodwin property was a historical illegal dump site that is being transformed into home sites targeted for low-to-moderate income families. The City’s Austin Brownfields Revitalization Office (ABRO) funded sev- eral environmental studies and a cleanup plan on the property. The cleanup plan activities have begun. Upon completion of the cleanup, the property owner (Guadalupe Neighborhood Development Corporation) anticipates receipt of a “Certificate of Completion” from the Texas Commission on Environmental Quality (TCEQ). The planned revitalization by this non-profit community development group is to build an afford- able subdivision with 80-90 homes and townhomes which will sell for $50,000 to $150,000. The homes will also be equipped with solar-electric and solar-thermal energy features. The City’s Austin Brownfields Revitalization Office le- verages and partners with eligible brownfield property owners, neighborhood groups, community organiza- tions, and governmental entities to address the reuse of brownfield properties.

Confused by all the attention on being “green”? Trying to figure out how you can do your part to protect our climate, water and air while still con- serving water and our many natural resources? The City of Austin has solved the problem with its updated Green Neigh- bor program. Previously geared to water quality protection strategies, the program is now greatly expanded to provide Austinites with a comprehen- sive guide to environmental protection. The new booklet is a compilation of action items that include tips for saving energy and water, and reducing air pollution, gardening chemicals and waste. Eleven City departments col- laborated on the effort that is subtitled the Green City Challenge. We are challenging citizens to test their environmental expertise and better yet, to change their habits and become Green Neighbors. The booklet serves as a resource for Austinites. It contains not only action items, but stats on why these green strategies are beneficial. It also lists contact information and websites for City rebates and program informa- tion. Austinites can learn how to enjoy the environment with links to our parks and preserves or to simply find the best bus route to work. The program has its rewards. Each action item has an associated score and if an individual or family reaches the Green Neighbor scoring goal, they can receive either a free t-shirt or a pass to Barton Springs Pool. If they want to partner with neighbors or co-workers, they can become a Green Neighborhood to receive website recognition and other benefits. The Challenge is available online at www.cityofaustin.org/watershed/ greenneighbor or booklets are available at all Austin public libraries.
