FORUM SUMMARY : Development Details: Sustainability Plan adopted as part of the Southlake 2030 Comprehensive Plan. Contains prioritized recommendations to maximize the efficient use of public resources • Creek Buffer – Tier 1 recommendation of Sustainability Plan o Intention is to reduce erosion, preserve habitat, increase open space, and minimize impacts from site development and increases in impervious coverage o Benefits of creek buffer is they can be used as nonstructural stormwater filtering and infiltration zones, keeps structures out of the floodplain, provides ROW for large flood events, and helps preserve riparian ecosystems and habitats o This ties back in to the adopted Integrated Stormwater Management Manual (iSWM) – another recommendation from the Sustainability Plan to adopt recommendations within that document • Proposed amendments to Ord. No. 480 (stream/creek buffer): o Allow bufferyard credit on property boundary containing buffer or on boundaries parallel to the buffer o Allow 1 for 1 tree credit for saving native trees within the border o For sites that have a meandering stream or a stream that runs diagonally through the site the credit would work differently • Proposed amendments to Ord. No. 480 (permeable pavement): o Consider incentivizing permeable pavement (such as credits toward impervious coverage limitations) – Tier 2 Recommendation in Sustainability Master Plan o Benefits of permeable pavement include: reduces stormwater runoff, allows rainfall to percolate into the soil rather than sheet flowing into waterways, reduces surface temperatures, and reduces pooling of water during rain events o Permeable concrete and asphalt would be allowed to serve as an offset if a developer wishes to increase impervious coverage over the maximum that is allowed o Ordinance amendment would allow for up to a 5% increase in that maximum impervious coverage if a minimum amount of permeable surface is used o Ordinance would also add a definition for permeable pavement and it would allow permeable pavers to be approved on a case by case basis o Systems using grass or gravel would not quality as a permeable all- weather surface Exhibits presented at SPIN: QUESTIONS / CONCERNS: None SPIN Meeting Reports are general observations of SPIN Meetings by City staff and SPIN Representatives.
