Zoning and Platting Commission Resolution Whereas, the Austin City Council passed Resolution 20220609-061 “relating to environmental protections and water quality”; and Whereas, the City Council directed the City Manager “to address the equitable protection of the environment throughout the City of Austin as part of the Watershed Protection Strategic Plan’; and Whereas, the proposed regulations include green stormwater infrastructure and functional green to lessen the heat island effect and provide other benefits; and Whereas, the proposed regulations lessen environmental reviews for some projects including water quality controls, critical environmental features, construction on slopes and watershed impervious cover limits; and Whereas, the City of Austin Zoning and Platting Commission welcomes improved environmental protections and water quality throughout the entire City. Now, therefore, be it resolved that the Zoning and Platting Commission encourages the Austin City Council to approve C20-2022-005a, Land Development Code Amendments with the following changes: • Implementation of Functional Green requirements will be deferred until such time as the Emergency Rules for the Environmental Criteria Manual is adopted to reflect the appropriate Criteria; • Allow boat dock access to remain within 50’ of the Lake as it relates to items 25-8-25 (B)(2), 25-8-27 (D)(2) • Under Section 25-8-64(E) for lots that cannot meet this criteria a mechanism to allow smaller units will be developed • Remove 25-8-213(A)(1) proposed changes • Clarify that the impervious cover limit in § 25-5-3 (B)(13)(b) is the impervious cover allowed by the zoning not to exceed 55%, Be it further resolved as Part of Phase 2 of Council initiated code updates that the following directions from the Council resolution be completed as soon as possible: • Require the environmental staff to work with Austin’s Equity Office to address inequities created by different rules for the Desired Development Zone and Critical Water Quality Zones such as Barton Springs; • Once the Affordability impact is determined any negative aspects will be counter balanced with incentives to ensure that there is no negative financial impact of these new requirements; • Recommend that all subdivisions and site plans in Urban Watersheds meet steep slope protections; and • Recommend new and redeveloped projects to use greenfield conditions as a baseline when calculating drainage requirements

Development Services Department Staff Recommendations Concerning Required Findings Project Name: Ordinance Standard: Watershed Protection Ordinance Variance Request: BKO Parmer To allow for fill exceeding 4 feet up to 12 feet for building construction Include an explanation with each applicable finding of fact. A. Land Use Commission variance determinations from Chapter 25-8-41 of the City Code: 1. The requirement will deprive the applicant of a privilege available to owners of similarly situated property with approximately contemporaneous development subject to similar code requirements. Yes. The variance will not be providing a special privilege to the applicant. The proposed buildings are similar in size to similarly situated property. In order to facilitate this type of development levelling and additional fill is required for the buildings. Prior projects in this area had a similar situation. A prime example is Crossroad Logistics Center Additions, SP-2021-0169D. A Land Use Commission variance was granted to LDC 25-8-342 to allow fill up to 17 feet. 2. The variance: a) Is not necessitated by the scale, layout, construction method, or other design decision made by the applicant, unless the design decision provides greater overall environmental protection than is achievable without the variance; Yes. Existing site conditions necessitate additional “fill” for fulfilling the requirements of two fire lane/emergency access routes as well as structural bridge for spanning the CWQZ. b) Is the minimum deviation from the code requirement necessary to allow a reasonable use of the property; Yes. The site is being graded as efficiently as possible to provide the required access slopes and bridge heights to minimize the amount of variance required. c) Does not create a significant probability of harmful environmental consequences.

Draft – 9/1/22 C20-2022-005a ORDINANCE AMENDMENT REVIEW SHEET Amendment: C20-2022-005a, Land Development Code Amendments Description: Consider an ordinance regarding amendments to Title 25 related to environmental protection and landscape requirements. Proposed Language: Draft language is included as Attachment A. Summary of proposed code changes: A summary of the proposed code changes is included as Attachment B. Background: This ordinance responds to Council Resolution No. 20220609-061, which initiated Land Development Code amendments related to environmental, drainage, and landscape requirements. The resolution directed staff to present most of the initiated amendments to Council for consideration by September 15, 2022. The initiated code amendments and a summary of the staff proposal is provided below: 1. Establish criteria that prioritize when green stormwater methods should be required or incentivized over conventional stormwater controls; The proposed code amendments would require most sites to use green stormwater infrastructure, or GSI, to meet water quality treatment requirements. This amendment was previously proposed and reviewed as part of the Land Development Code (LDC) Revision. Under current code, many sites meet water quality treatment requirements by building a sedimentation/filtration pond. Sedimentation/filtration devices provide some water quality benefits by filtering polluted runoff and helping control stream-channel erosion, but they do not significantly address other important ancillary goals such as supporting on-site vegetation, increasing rainwater infiltration, and reducing potable water consumption. Requiring most sites to use GSI instead of conventional grey stormwater infrastructure will provide myriad benefits, including stormwater infiltration, soil health, wildlife habitat, urban heat island mitigation, water conservation, aesthetic value, and other ecosystem services. GSI also provides enhanced water quality benefits compared to sedimentation/filtration devices, including better removal of nutrients from stormwater and further reductions in erosive flows. The proposed code amendments would allow developments to choose from a variety of green stormwater controls, including biofiltration ponds, rain gardens, rainwater harvesting systems, porous pavement, and retention-irrigation systems (which can be built in conjunction with green roofs). All of these systems beneficially use rainwater to infiltrate and/or offset potable water. Staff also proposes to increase the beneficial use benefits of these controls over time through improvements to the design criteria in the Environmental Criteria Manual. 1 Draft – 9/1/22 C20-2022-005a The proposed code amendments provide some exceptions from the GSI requirement, allowing conventional controls to be used for sites with more than 90 percent impervious cover, regional ponds, difficult site conditions, and “hot-spot” land uses with highly contaminated runoff (e.g., …

Bristol WHEREAS, the Environmental Commission recognizes the applicant is seeking the removal of a Heritage tree with a single stem over 30 inches in diameter and; WHEREAS, the Environmental Commission recognizes the request meets City Arborist approval criteria set forth in LDC 25-8-624(A)(2) and that staff recommends this variance; WHEREAS, the Environmental Commission recognizes mitigation for this site shall be addressed by planting two (2) Live Oaks at 5-inch caliper as street trees. These two trees are proposed to have adequate soil to ensure survivability and, when planted, will have a combined crown surface area that will rival the thinning canopy of the existing 32-inch Live Oak. In addition, the remaining inches owed will be paid to the Urban Forest Replenishment Fund for a total of $18,500. THEREFORE, the Environmental Commission recommends the variance request with the following Environmental Commission Conditions: 1.
