PASSION. PROSPERITY. August 27, 2008 Edwards Aquifer Protection Program of the Austin Region Texas Commission on Environmental Quality % Ms. Carolyn Runyon, Water Program Manager 2800 South IH 35, Suite 100 Austin, Texas 78704 Re: Exception Request for Meadow Lake Park North Trail Development Project in Round Rock, Texas CN: 600413181 Dear Ms. Runyon: Enclosed are the TCEQ Edwards Aquifer Recharge Zone Exception Request Application forms for the City of Round Rock Meadow Lake Park North Trail Development Project. In this application an exception from the requirements of filing a Water Pollution Abatement Plan (WPAP), performing a Geologic Assessment, and providing permanent water quality controls for this project is being requested. The Meadow Lake Park North Trail Development Project consists of developing approximately 21.87 acres of existing open parkland with a pavilion and approximately '/2 mile of 6' wide concrete trail. The total amount of planned impervious cover will be approximately 16,550 square feet or less than four tenths (.40) of an acre. We request an exception from the requirements to file a Water Pollution Abatement Plan (WPAP), to install permanent water quality controls and to provide a geologic assessment for the project. Because the impervious cover being added by the project is a small amount, the depth of excavation disturbance is minimal, and the storm water from the project will flow over a vegetated surface for the majority of its flow, we feel the project will not negatively affect the Edwards Aquifer, and our request is justified. Enclosed for your review is one (1) original application with the required attachments, three (3) full copies of the application package, four (4) sets of the construction plans, two checks made payable to the Texas Commission on Environmental Quality each in the amount of $250.00 for the $500.00 application fee, and letter of No Comment for the City of Round Rock. We appreciate your expeditious review of this application. We look forward to your response.

The request was prepared by: David Buzzell, RLA Print Name of Customer/Agent Signature of Customer/Agent TCEQ-0628 (Rev. 10/01/04) Date ATTACHMENT A — Nature of Exception This exception request is to allow for the construction of a small net increase in impervious cover, within an area where there is a Targe amount of existing pervious cover, without filing a Water Pollution Abatement Plan (WPAP), performing a Geologic Assessment, and providing permanent water quality controls. The project consists of developing existing open parkland, approximately 21.87 acres, with a pavilion and approximately 1/2 mile of 6' wide concrete trail with other park amenities, including park benches and picnic tables. The total amount of planned impervious cover will be approximately one quarter (.38) acre. The project is small enough that the construction time will be short. TCEQ-0628 Page 2 of 3 ATTACHMENT B — Documentation of Equivalent Water Quality Protection The construction will produce a small increase in impervious cover. The excavation will hold the storm water until it can be handled by the contractor. The vast majority of the storm water falling on or flowing across the completed project will flow on undeveloped grassland. There should be some water quality benefit from the storm water traveling over undeveloped grassland prior to discharge to Meadow Lake.

N/A The TCEQ Technical Guidance Manual (TGM) was used to design permanent BMPs and measures for this site. Pilot -scale field testing (including water quality monitoring) may be required for BMPs that are not contained in technical guidance recognized by or prepared by the executive director. ATTACHMENT H - Pilot -Scale Field Testing Plan. A plan for pilot -scale field testing is provided at the end of this form. 13. N/A ATTACHMENT I -Measures for Minimizing Surface Stream Contamination. A description of the measures that will be used to avoid or minimize surface stream contamination and changes in the way in which water enters a stream as a result of the construction and development is provided at the end of this form. The measures address increased stream flashing, the creation of stronger flows and in -stream velocities, and other in -stream effects caused by the regulated activity which increase erosion that results in water quality degradation. Responsibility for maintenance of permanent BMPs and measures after construction is complete. 14. N/A The applicant is responsible for maintaining the permanent BMPs after construction until such time as the maintenance obligation is either assumed in writing by another entity having ownership or control of the property (such as without limitation, an owner's association, a new property owner or lessee, a district, or municipality) or the ownership of the property is transferred to the entity. Such entity shall then be responsible for maintenance until another entity assumes such obligations in writing or ownership is transferred. 15. N/A A copy of the transfer of responsibility must be filed with the executive director at the appropriate regional office within 30 days of the transfer if the site is for use as a multiple single-family residential development, a multi -family residential development, or a non-residential development such as commercial, industrial, institutional, schools, and other sites where regulated activities occur.

In this application an exception from the requirements of filing a Water Pollution Abatement Plan (WPAP), performing a Geologic Assessment, and providing permanent water quality controls for this project is being requested. The Bowman Park Development Project — Phase I consists of developing approximately 8.5 acres of existing open parkland with a playscape and approximately 1/4 mile of 6' wide crushed decomposed granite trail with 6" concrete ribbon curb on either side. The total amount of planned impervious cover will be approximately two thousand nine hundred (2,900) square feet or less than seven hundredths (.07) of an acre on an 8.5 acre undeveloped park site. We request an exception from the requirements to file a Water Pollution Abatement Plan (WPAP), to install permanent water quality controls and to provide a geologic assessment for the project. Because the impervious cover being added by the project is a small amount, the depth of excavation disturbance is minimal, and the storm water from the project will flow over a vegetated surface and be filtered through the decomposed granite before entering the recharge zone, we feel the project will not negatively affect the Edwards Aquifer, and our request is justified. Enclosed for your review is one (1) original application with the required attachments, three (3) full copies of the application package, four (4) sets of the construction plans, two checks made payable to the Texas Commission on Environmental Quality each in the amount of $250.00 for the $500.00 application fee, and letter of No Comment for the City of Round Rock.

CONTOUR INTERVAL 10 FEET NATIONAL GEODETIC VERTICAL DATUM OF 1929 TCEQ-0587 Page 8 of 35 ATTACHMENT C — Project Description The Bowman Park Development Project — Phase I consists of developing approximately 8.5 acres of existing open parkland with a playscape and approximately % mile of crushed decomposed granite trail with 6" concrete ribbon curb on either side. The total amount of planned additional impervious cover will be approximately .06 acres, with the mazimum depth disturbance for the construction to be less than two feet (2'). Storm water runoff leaving the proposed construction site will flow to the east along the existing grass drainage swale running east -west through the property. At the eastern boundary, the swale becomes a concrete lined trickle channel and continues through an adjacent residential area, and is captured in curb inlets. The curb inlets transfer the flow to an underground pipe storm sewer system, which releases the flow on the east side of Sunrise Drive to the point of discharge into the Chandler Creek. See `ATTACHMENT D — Storm Water Discharge Map'. Due to the facts that the project will create a small net increase in impervious cover, that the depth of the construction excavation will be minimal, and that the majority of the storm water that falls on the completed project will sheet flow across vegetated surfaces and into a shallow vegetated swale, an exception from the requirements of filing a Water Pollution Abatement Plan (WPAP), performing a Geologic Assessment, and providing permanent water quality controls for the project is being requested.

This RECHARGE AND TRANSITION ZONE EXCEPTION REQUEST FORM application is hereby submitted for TCEQ review and executive director approval. The request was prepared by: David Buzzell, RLA Print Name of Customer/Agent re of Customer/Agent TCEQ-0628 (Rev. 10/01/04) ATTACHMENT A — Nature of Exception This exception request is to allow for the construction of a small net increase in impervious cover, within an area where there is a large amount of existing pervious cover, without filing a Water Pollution Abatement Plan (WPAP), performing a Geologic Assessment, and providing permanent water quality controls. The project consists of developing existing open parkland, approximately 8.5 acres, with a pavilion and approximately 1/2 mile of 6' wide concrete trail with other park amenities, including park benches and picnic tables. The total amount of planned impervious cover will be approximately two thousand six hundred (2600) square feet, or six hundredths (.06) of an acre. The project is small enough that the construction time will be short. TCEQ-0628 Page 2 of 3 ATTACHMENT B — Documentation of Equivalent Water Quality Protection The construction will produce a small net increase in impervious cover. The excavation will hold the storm water until it can be handled by the contractor. The vast majority of the storm water falling on or flowing across the completed project will be absorbed or flow through the vegetated swale and into a concrete channel. There will be some water quality benefit from the storm water permeating not only the vegetated areas of the park, but also the decomposed granite trail, prior to discharge to Chandler Creek.

Written construction notification must be given to the appropriate TCEQ regional office no later than 48 hours prior to commencement of the regulated activity. Information must include the date on which the regulated activity will commence, the name of the approved plan for the regulated activity, and the name of the prime contractor and the name and telephone number of the contact person. 2. All contractors conducting regulated activities associated with this project must be provided with complete copies of the approved Water Pollution Abatement Plan and the TCEQ letter indicating the specific conditions of its approval. During the course of these regulated activities, the contractors are required to keep on-site copies of the approved plan and approval letter. 3. If any sensitive feature is discovered during construction, all regulated activities near the sensitive feature must be suspended immediately. The appropriate TCEQ regional office must be immediately notified of any sensitive features encountered during construction. The regulated activities near the sensitive feature may not proceed until the TCEQ has reviewed and approved the methods proposed to protect the sensitive feature and the Edwards Aquifer from any potentially adverse impacts to water quality. 4. No temporary aboveground hydrocarbon and hazardous substance storage tank system is installed within 150 feet of a domestic, industrial, irrigation, or public water supply well, or other sensitive feature. 5. Prior to commencement of construction, all temporary erosion and sedimentation (E&S) control measures must be properly selected, installed, and maintained in accordance with the manufacturers specifications and good engineering practices. Controls specified in the temporary storm water section of the approved Edwards Aquifer Protection Plan are required during construction. If inspections indicate a control has been used inappropriately, or incorrectly, the applicant must replace or modify the control for site situations. The controls must remain in place until disturbed areas are revegetated and the areas have become permanently stabilized. 6. If sediment escapes the construction site, off-site accumulations of sediment must be removed at a frequency sufficient to minimize offsite impacts to water quality (e.g., fugitive sediment in street being washed into surface streams or sensitive features by the next rain). 7. Sediment must be removed from sediment traps or sedimentation ponds not later than when design capacity has been reduced by 50%. A permanent stake must be provided that can indicate when the sediment occupies 50% of the basin volume. 8. Litter, construction debris, and construction chemicals exposed to stormwater shall be prevented from becoming a pollutant source for stormwater discharges (e.g., screening outfalls, picked up daily). 9. All spoils (excavated material) generated from the project site must be stored on-site with proper E&S controls. For storage or disposal of spoils at another site on the Edwards Aquifer Recharge Zone, the owner of the site must receive approval of a water pollution abatement plan for the placement of fill material or mass grading prior to the placement of spoils at the other site. TCEQ-0592 (Rev. 3/15/07) Page 1 of 2 10. Stabilization measures shall be initiated as soon as practicable in portions of the site where construction activities have temporarily or permanently ceased, but in no case more than 14 days after the construction activity in that portion of the site has temporarily or permanently ceased. Where the initiation of stabilization measures by the 14th day after construction activity temporary or permanently cease is precluded by weather conditions, stabilization measures shall be initiated as soon as practicable. Where construction activity on a portion of the site is temporarily ceased, and earth disturbing activities will be resumed within 21 days, temporary stabilization measures do not have to be initiated on that portion of site. In areas experiencing droughts where the initiation of stabilization measures by the 14th day after construction activity has temporarily or permanently ceased is precluded by seasonal arid conditions, stabilization measures shall be initiated as soon as practicable. 11. The following records shall be maintained and made available to the TCEQ upon request: the dates when major grading activities occur; the dates when construction activities temporarily or permanently cease on a portion of the site; and the dates when stabilization measures are initiated. 12. The holder of any approved Edward Aquifer protection plan must notify the appropriate regional office in writing and obtain approval from the executive director prior to initiating any of the following: A. any physical or operational modification of any water pollution abatement structure(s), including but not limited to ponds, dams, berms, sewage treatment plants, and diversionary structures; B. any change in the nature or character of the regulated activity from that which was originally approved or a change which would significantly impact the ability of the plan to prevent pollution of the Edwards Aquifer; C. any development of land previously identified as undeveloped in the original water pollution abatement plan.

TCEQ-0592 (Rev. 3/15/07) Page 2 of 2 DATE: August 29, 2008 SUBJECT: City Manager Approval - September 5, 2008 ITEM: Consider executing a Recharge Zone Exception Request with TCEQ for the Meadow Lake Park North Trail Development Project. Department: Parks and Recreation Department Staff Person: Rick Atkins David Buzzell, RLA, ASLA Justification: Due to the two project sites being located over the Edwards Aquifer Recharge Zone, the City is required to submit an application to the Texas Commission on Environmental Quality. The projects have minimal added impervious cover and therefore we are requesting an exception to the TCEQ requirements. Funding: $250,000.00 Cost: $0.00 Source of funds: Parkland Dedication Funds Outside Resources: Texas Commission on Environmental Quality Background Information: Meadow Lake Park is a Community park divided into 2 areas. The south portion of the park is currently developed with a concrete trail and playground. Public Comment: Public input gathered at multiple public meetings. Residents were interested in more recreational opportunities in north portion of the park.
