City Council Meeting Minutes March 19, 2019 <br />event. The 2015 flood was closer to a 200 -year event. Staff is ensuring the <br />proposed SMART terminal development will not increase flooding, but <br />actually decrease the runoff. Council Member Rockeymoore asked for an <br />explanation of the impact of the 200 -year flood to that area. Staff is looking at <br />climate change and we are experiencing more intense rainfall events. The <br />development agreement does speak to this categorized by Atlas 14 (data over a <br />longer period of time) and the developer must look at their improvements <br />utilizing Atlas 14 data. The developer is required to be two feet above the <br />100 -year floodplain elevation. They have to mitigate fill they bring in to elevate <br />their buildings with cut so there is no loss of floodplain storage. <br />Council Member Marquez inquired about the effect of additional drainage <br />from this site would cause to Tributary 1 and how much additional drainage <br />would Tributary 1 and Bypass Creek expect to receive during and after <br />development. Ms. Moyer stated that each tributary would see 10% less flow <br />than the property currently experiences undeveloped. Council Member <br />Marquez inquired about the proximity of this development to defined <br />environmentally sensitive areas. Ms. Moyer went back to one of the tools used <br />in the Comprehensive Plan, the land suitability map, which maps all the <br />environmental constraints in our City Limits and ETJ. The suitability map is <br />ranked 1-5, with 5 being the most environmentally constrained and 1 being the <br />least environmentally constrained. The SMART terminal site is identified as a <br />2. Council Member Marquez asked about the effect unregulated drainage <br />would have on the City. Ms. Moyer stated that development occurs where we <br />allow it in regards to the detriment of life for not only us, but our neighbors <br />and to future citizens. <br />Council Member Prewitt stated this council cares greatly about the quality of <br />life for our citizens and how much we care for our community, the river, and <br />the recharge zone. None of us take this lightly and we understand the concern <br />and worry of citizens. There have been intense floods in the past, but what we <br />have heard from our Staff is that we work hard we can develop San Marcos <br />and make it safe. Building a strong relationship with the developers is very <br />important, this can really create positive outcomes in the future. Many of us <br />were activists before we became Council Members, and we had little trust, but <br />we have worked hard to build trust with our citizens. She expressed her <br />appreciation to everyone that has commented and asked questions and she <br />feels this has made the product better. She stated she will support this <br />development and this will be better for the environment than what is there <br />right now. If we say no to these agreements, we could lose this project. There is <br />still a willing seller and if we say no the future buyer may not be as excited to <br />City of San Marcos Page 12 <br />
