ITEM FOR ENVIRONMENTAL COMMISSION AGENDA COMMISSION MEETING DATE: NAME & NUMBER OF PROJECT: NAME OF APPLICANT OR ORGANIZATION: 01/20/21 Allegro Parmer, SP-2019-0170C Michele Rogerson Lynch LOCATION: 4001 W. Parmer Ln, Austin, TX 78727 COUNCIL DISTRICT: District 7 ENVIRONMENTAL REVIEW STAFF: WATERSHED: REQUEST: STAFF RECOMMENDATION: STAFF CONDITION: Kristy Nguyen, Environmental Review Specialist, Sr., Development Services Department, 512-974-3035, Kristy.Nguyen@austintexas.gov Walnut Creek, Suburban, Desired Development Zone Variance request is as follows: Request to vary from LDC 25-8-261 to allow construction in a critical water quality zone Staff recommends this variance, having determined the findings of fact to have been met. 1) Fully dismantle the existing water quality and detention pond, including pond appurtenances and underdrains, and provide restoration in accordance to the City’s 609.S standards and specifications; 2) Clean up debris and trash along the portion of Yett Branch creek located at the southern property boundary of the commercial subdivision; and 3) Design the fire lane turnaround within the CWQZ in accordance with ECM 1.6.7 to reduce pollutant load and impervious cover.  Staff Findings of Fact and Exhibits  Development Services Department Staff Recommendations Concerning Required Findings Project Name: Allegro Parmer, SP-2019-0170C Ordinance Standard: Watershed Protection Ordinance Variance Request: LDC 25-8-261 to allow development within a critical water quality zone Include an explanation with each applicable finding of fact. A. Land Use Commission variance determinations from Chapter 25-8-41 of the City Code: The property is within a commercial subdivision, surrounded by similar 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 development and zoning. Additionally, a majority of the site is within the critical water quality zone and has been extensively disturbed through previously permitted development to construct a parking lot and a water quality and detention pond. Without a variance to LDC 25-8-261, the applicant is deprived of the privilege to redevelop this property such that the property would likely remain in its existing condition as an unutilized parking lot. 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 The uplands of the property are confined to existing easements that serve the commercial subdivision. Furthermore, a majority of the site (approximately 2.7 ac of 3.97 ac) is within a critical water quality zone. For these reasons, options to develop the site are infeasible without necessitating a variance to LDC 25- 8-261. Additionally, previously permitted development within the inner half of the critical water quality zone, including the undersized water quality and detention pond, will be decommissioned and restored to City Standard Specification 609.S. The proposed water quality and detention pond will be located further away from the creek centerline and outside of 1. 2. the inner half of the critical water quality zone, providing greater overall environmental protection. Is the minimum deviation from the code requirement necessary to allow a reasonable use of the property; The proposed use is reasonable, and there will be a decrease of impervious cover of the overall site (approximately -6,000 sq ft) and within the critical water quality zone (approximately - 1,250 sq ft). Furthermore, the proposed development largely coincides with the boundary of the existing parking lot, thereby not extending impervious cover further into the critical water quality zone. Does not create a significant probability of harmful environmental consequences. b) c) Yes Yes There will be a net reduction of impervious cover of the overall site and within the critical water quality zone. Moreover, the existing water quality and detention pond within the inner half of the critical water quality zone, approximately 100 ft from the creek centerline, is inadequately sized and does not properly treat the runoff before it enters Yett Branch creek. With this variance, the existing pond will be dismantled, including the removal of the underdrains, and will be fully restored to City Standard Specification 609.S. The proposed water quality and detention pond will be located outside of the inner half of the critical water quality zone and will be constructed to current code and regulation standards. Development with the variance will result in water quality that is at least equal to the water quality achievable without the variance. Yes The existing water quality pond treating the pollutant load from the impervious cover of the parking lot is undersized and does not comply with current code. With this variance, not only will the pond be properly sized to treat runoff for the entire site, but also will be located further away from the creek centerline and outside of the inner half of the critical water quality zone. B. The Land Use Commission may grant a variance from a requirement of Section 25-8-422 (Water Supply Suburban Water Quality Transition Zone), Section 25-8-452 (Water Supply Rural Water Quality Transition Zone), Section 25-8-482 (Barton Springs Zone Water Quality Transition Zone), Section 25-8-368 (Restrictions on Development Impacting Lake Austin, Lady Bird Lake, and Lake Walter E. Long), or Article 7, Division 1 ( Critical Water Quality Zone Restrictions ), after determining that:: 3. 1. The criteria for granting a variance in Subsection (A) are met; Yes The findings of fact in Subsection A are met. Yes Yes 2. The requirement for which a variance is requested prevents a reasonable, economic use of the entire property; In its existing conditions as an unutilized parking lot with easements shared with the adjacent businesses, options to redevelop the site without disturbing the existing parking lot islands scattered throughout the site are limited without necessitating a variance to LDC 25-8-261. Therefore, any design except a parking lot would be unworkable. Granting this variance would allow full economic use of the property to develop a commercial business within the commercial subdivision. 3. The variance is the minimum deviation from the code requirement necessary to allow a reasonable, economic use of the entire property. There will be a reduction of impervious cover of the entire site and within the critical water quality zone. Additionally, the proposed development will largely remain within the existing parking lot boundary. The variance is the minimum deviation from the code requirement and would allow a reasonable and economic use of the entire property by converting an unused parking lot into a commercial business. Staff Determination: Staff determines that the findings of fact have. Staff recommends the following conditions: 1) Fully dismantle the existing water quality and detention pond, including pond appurtenances and underdrains, and provide restoration in accordance with City Standard Specification 609.S; 2) Clean up debris and trash along the portion of Yett Branch creek located at the southern property boundary of the commercial subdivision; and 3) Design the fire lane turnaround within the CWQZ in accordance with ECM 1.6.7 to reduce pollutant load and impervious cover.

The site slopes down from North at an elevation of 778 MSL to South at an elevation of 753 MSL. The site drains towards Yett Branch Creek directly south of the site which has a creek bed elevation of approximately 748 MSL. The average slope throughout the site is between 0-15% slope. The subject property currently consists of a parking lot that is within the CWQZ and HALF CWQZ. A portion of the site is within the 100-year floodplain along the southern portion of the property. A Spring CEF exists in the creek south of the subject property. The site consists of an existing water quality pond not up to current ECM standards that lies within the HALF CWQZ. There are existing wastewater utilities and easements on the north side of the property that serve the adjacent lots to the north east, and west. These utilities and easements are conveyed through the subject property (DOC #199900219). Seven (7) heritage trees exist on site and will not be impacted by the proposed development. Please reference the mentioned above including the tree list on the Existing Conditions Sheet (EXHIBIT 7). City of Austin | Environmental Commission Variance Application Guide 2 December 3, 2020 Clearly indicate in what way the proposed project does not comply with current Code (include maps and exhibits) FINDINGS OF FACT JUSTIFICATION: 1. The proposed redevelopment layout does not match the exact footprint of the existing impervious cover and is within the CWQZ. LDC 25-8-261 (CWQZ Development) is the code that is triggering non-compliance . In addition, this property, and any other property along the CWQZ in this area are similar in that without the ability to utilize the Redevelopment Exception due to the unusual configuration of the existing surface parking lot or obtain a variance, the property will remain largely a surface parking lot with excessive parking that is not being used to its full capacity, which does not allow to improve the environment. As required in LDC Section 25-8-41, in order to grant a variance the Planning Commission must make the following findings of fact: Include an explanation with each applicable finding of fact. Project: SP-2019-0170C Ordinance: LDC 25-8-261 Critical Water Quality Zone Development A. Land Use Commission variance determinations from Chapter 25-8-41 of the City Code: 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/NO This property, and any other property along the CWQZ in this area are similar in that without the ability to utilize the Redevelopment Exception due to the unusual configuration of the existing surface parking lot or obtain a variance, the property will remain largely a surface parking lot with excessive parking that is not being used to its full capacity, which does not allow to improve the environment. Please note the existing undersized water quality (WQ) pond is not to current to ECM code and is also within the ½ Critical Water Quality Zone. The proposed development will provide a new subsurface WQ pond designed to current City code and will be located under the building and outside of the ½ CWQZ. City of Austin | Environmental Commission Variance Application Guide 3 December 3, 2020 2. The variance: a) The existing WQ pond will no longer be utilized and landscape restoration will be provided within the existing pond. A natural earthen soft trail will also be added around the existing WQ pond to create natural open space to help enhance the natural features of the land. 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/NO The proposed development will replace an existing surface parking lot that was part of a larger development. A portion of the existing surface parking lot is being purchased for redevelopment. The proposed site development is providing an assisted senior living facility with water quality and natural vegetative improvements. The design improvements will provide greater overall environmental protection than is achievable without the variance. As mentioned earlier in Section 1, the existing conditions consists of an oversized parking lot and undersized water quality pond within the ½ CWQZ that is not up to current ECM code. The proposed development will provide a new subsurface WQ pond designed to current City code and will be located under the building and outside of the ½ CWQZ. The existing WQ pond will no longer be utilized and landscape restoration will be provided within the existing pond. A natural earthen soft trail will also be added around the existing WQ pond to create natural open space to help enhance the natural features of the land. In addition, the proposed conditions for the site will not increase the overall impervious cover and they will not increase impervious cover within the CWQZ. Additionally, there will be no adverse impact to the 100-year floodplain from the proposed development. In regards to the design of the proposed site plan and building placement, this was driven based on several existing site constraints. One of the major site constraints consists of existing the wastewater utilities and easements on the north side of the property that serves the adjacent lots to the north east, and west. These utilities and easements are conveyed through our property and we will need to maintain these utilities and easements to allow adequate service for the adjacent properties. City of Austin | Environmental Commission Variance Application Guide 4 December 3, 2020 We have coordinated with Austin Water on designing and connecting to the existing wastewater system and easements. Austin Water has required us to provide a 26’ wastewater easement based on the depth of the wastewater line to the north of the site. The new 26’ wastewater easement along with connecting to the existing wastewater easement is what dictated the placement of the proposed building. In addition, there is a fire access easement to the north of the property that is required to allow fire access for the adjacent lots to the north, east, west, as well as the rest of the subdivision. This was another driven force for the placement of the proposed building. b) Is the minimum deviation from the code requirement necessary to allow a reasonable use of the property; YES/NO Due to the current parking lot configuration, excessive parking spaces not being utilized, and a portion of the lot being within the CWQZ, the City code LDC 25-8-25 (C)(5) does not allow the site to have reasonable, economic use of the property without the Redevelopment and thus a variance is required to a minimum deviation. The site would benefit from the proposed redevelopment because it would make the space into a senior home living facility for the community with proper WQ controls to treat runoff discharging to the creek south of the site. This would be a significant improvement from its current conditions which is acting as impervious cover surface for contaminated runoff to flow over towards an existing WQ pond not to city code standards. In addition, we are improving the environmental protection of the property by providing natural open vegetative space within the ½ CWQZ and providing landscape restoration within the existing WQ pond. As mentioned earlier in the previous section (Sec. 2a), north of the proposed senior home living facility building, there are existing wastewater service lines and easements which serve adjacent properties. These services must be maintained and therefore adds hardship to the development by forcing the proposed conditions to stay clear of these utilities. c) Does not create a significant probability of harmful environmental consequences. YES/NO This site is not increasing the overall impervious cover (which is under code allowances) and is not increasing impervious cover within the CWQZ. There will also be no adverse impact to the 100-year floodplain from the proposed development. City of Austin | Environmental Commission Variance Application Guide 5 December 3, 2020 We are providing for structured parking results in the removal of expansive surface parking with pollutant runoff. 3. Development with the variance will result in water quality that is at least equal to the water quality achievable without the variance. YES/NO The one (1) existing WQ pond on site does not meet the criteria in the current City ECM code standards. The proposed development would improve the overall environmental protection by replacing the existing WQ pond with a subsurface sedimentation/filtration WQ pond outside of the ½ CWQZ. The proposed WQ pond provides more efficient and effective environmental protection by providing increased capture volume and reducing pollutant runoff compared to existing conditions. B. Additional Land Use Commission variance determination for a requirement of Section 25-8-422 (Water Quality Transition Zone), Section 25-8-452 (Water Quality Transition Zone), Article 7, Division 1 (Critical Water Quality Zone Restrictions), or Section 25-8-652 (Development Impacting Lake Austin, Lady Bird Lake, and Lake Water E. Long): 1. 2. The criteria for granting a variance in Subsection (A) are met; YES/NO The criteria for granting a variance in Subsection (A) have been met. Please reference explanations above. The requirement for which a variance is requested prevents a reasonable, economic use of the entire property; YES/NO Due to the requirement to match the existing impervious cover, it would not be possible to construct a continuous slab which would be needed for the senior home living facility because of the pervious islands throughout the existing parking. This property, and any other property along the CWQZ in this area are similar in that without the ability to utilize Redevelopment due to the unusual configuration of the existing surface parking lot or obtain a variance, the property will remain largely a surface parking lot with excessive parking that is not being used to its full capacity, which does not allow to improve the environment. Therefore, the applicant is requesting a variance for this requirement. 3. The variance is the minimum deviation for the code requirement necessary to allow a reasonable, economic use of the entire property. YES/NO The variance requested is the minimum departure for the code requirement necessary to provide enhancement of the site with a senior living facility and natural open space feature. City of Austin | Environmental Commission Variance Application Guide 6 December 3, 2020 Due to the current parking lot configuration, excessive parking spaces not being utilized, and a portion of the lot being within the CWQZ and ½ CWQZ, the City code LDC 25-8-25 (C)(5) does not allow the site to have reasonable, economic use of the property without the Redevelopment and thus a variance is required to a minimum deviation. ** Variance approval requires all above affirmative findings. City of Austin | Environmental Commission Variance Application Guide 7 November 9, 2020 EXHIBIT 1 City of Austin | Environmental Commission Variance Application Guide 9  November 11, 2020 Kristy Nguyen Environmental Reviewer, Land Use Development Development Services Department 505 Barton Springs Road Austin, TX 78704 Dear Ms. Nguyen: Subject: RE: 4001 West Parmer Lane (SP-2019-0170C) - ENV and Land Use Commission Variance CEC Project 303-185 As representatives of the owner of the above stated Property, CEC respectfully submits the enclosed Land Use Commission Variance to allow for the redevelopment of the existing surface parking lot from LDC 25-8-261 (development within the Critical Water Quality Zone). The project is located at 4001 West Parmer Lane, Austin, Texas 78727 and is approximately 3.97 acres. Currently, the site is an existing surface parking lot which is not used to its full capacity. The restriction imposed by city code per LDC 25-8-261 which requires the redevelopment of the site to match the existing impervious cover creates a hardship due to the islands in the parking lot creating pervious pockets in the existing impervious cover area which would prevent a continuous slab for a building being allowed where the current parking exists. One of the major site constraints consist of the existing wastewater lines and easements crossing the north and south side of the site. These existing wastewater lines serve the adjacent properties and must be maintained in their current configuration along the north portion of the lot to provide service. We have coordinated with Austin Water on designing and connecting to the existing wastewater system and easements to adequately maintain service for the adjacent properties while properly serving the proposed development. Austin Water has required us to provide a 26’ wastewater easement based on the depth of the existing wastewater line towards the north portion of the site. The new 26’ wastewater easement and connecting to the existing wastewater easement is what dictated the placement of the proposed building to be within the CWQZ. Please reference the Site Plan (Exhibit 8) for references of the existing and proposed easements. In addition, there is a fire access easement to the north of the property that is required to allow fire access for the adjacent lots to the north, east, west, as well as the rest of the subdivision. This was another driven force for the placement of the proposed building with the CWQZ. Kristy Nguyen – Land Use Development CEC Project 303-185 Page 2 11/11/2020 Please note the existing undersized water quality (WQ) pond is not to current to ECM code and is also within the ½ Critical Water Quality Zone. The proposed development will provide a new subsurface WQ pond designed to current City code and will be located under the building and outside of the ½ CWQZ. The proposed project would enhance the site by creating a senior living facility for the community which would include usable natural open space that enhances the environmental features surrounding the area. The existing WQ pond will no longer be utilized and landscape restoration will be provided within the existing pond, as well as a natural earthen soft trail surrounding the existing WQ pond. This is a significant environmental improvement compared to the existing conditions and provides economic use to the property. Please reference the landscape plan (EXHIBIT 9) for the landscape restoration plan within the existing water quality pond and natural open space/trail. We appreciate your consideration.
