The placement of erosion/sedimentation controls shall be in accordance with the Environmental Criteria Manual and the approved Erosion and Sedimentation Control Plan. T he COA ESC Plan shall be consulted and used as the basis for a TPDES required SWPPP. If a SWPPP is required, it shall be available for review by the City of Austin Environmental Inspector at all times during construction, including at the Pre-Construction meeting. The checklist below contains the basic elements that shall be reviewed for permit approval by COA EV Plan Reviewers as well as COA EV Inspectors. — Plan sheets submitted to the City of Austin MUST show the following: Direction of flow during grading operations. Location, description, and calculations for off-site flow diversion structures. Areas that will not be disturbed; natural features to be preserved. Delineation of contributing drainage area to each proposed BMP (e.g., silt fence, sediment basin, etc.). Location and type of E&S BMPs for each phase of disturbance. Calculations for BMPs as required. Location and description of temporary stabilization measures. Location of on-site spoils, description of handling and disposal of borrow materials, and description of on-site permanent spoils disposal areas, including size, depth of fill and revegetation procedures. Describe sequence of construction as it pertains to ESC including the following elements: 1. Installation sequence of controls (e.g. perimeter controls, then sediment basins, then temporary stabilization, then permanent, etc.) 2. Project phasing if required (LOC greater than 25 acres) 3. Sequence of grading operations and notation of temporary stabilization measures to be used 4. Schedule for converting temporary basins to permanent WQ controls 5. Schedule for removal of temporary controls 6. Anticipated maintenance schedule for temporary controls — Categorize each BMP under one of the following areas of BMP activity as described below: 3.1 Minimize disturbed area and protect natural features and soil 3.2 Control Stormwater flowing onto and through the project 3.3 Stabilize Soils 3.4 Protect Slopes 3.5 Protect Storm Drain Inlets 3.6 Establish Perimeter Controls and Sediment Barriers 3.7 Retain Sediment On-Site and Control Dewatering Practices 3.8 Establish Stabilized Construction Exits 3.9 Any Additional BMPs — Note the location of each BMP on your site map(s). — For any structural BMPs, you should provide design specifications and details and refer t othem. — For more information, see City of Austin Environmental Criteria Manual 1.4. 3. The Placement of tree/natural area protective fencing shall be in accordance with the City of Austin standard Notes for Tree and Natural Area Protection and the approved Grading/Tree and Natural Area Plan. 4. A pre-construction conference shall be held on-site with the contractor, design Engineer/ permit applicant and Environmental Inspector after installation of the erosion/sedimentation controls, tree/natural area protection measures and "Pre-Construction" tree fertilization (if applicable) prior to beginning any site preparation work. The owner or owner's representative shall notify the Development Services Department, 512-974-2278 or by email at environmental.inspections@austintexas. gov, at least three days prior to the meeting date. COA approved ESC Plan and TPDES SWPPP (if required) should be reviewed by COA EV Inspector at this time. 5. Any major variation in materials or locations of controls or fences from those shown on the approved plans will require a revision and must be approved by the reviewing Engineer, Environmental Specialist or City Arborist as appropriate. Major revisions must be approved by authorized COA staff. Minor changes to be made as field revisions to the Erosion and Sedimentation Control Plan may be required by the Environmental Inspector during the course of construction to correct control inadequacies. 6. The contractor is required to provide a certified inspector that is either a licensed engineer (or person directly supervised by the licensed engineer) or Certified Professional in Erosion and Sediment Control (CPESC or CPESC - IT), Certified Erosion, Sediment and Stormwater - Inspector (CESSWI or CESSWI - IT) or Certified Inspector of Sedimentation and Erosion Controls (CISEC or CISEC - IT) certification to inspect the controls and fences at weekly or bi-weekly intervals and after one-half (1⁄2) inch or greater rainfall events to insure that they are functioning properly. The person(s) responsible for maintenance of controls and fences shall immediately make any necessary repairs to damaged areas. Silt accumulation at controls must be removed when the depth reaches six (6) inches or one-third (1⁄3) of the installed height of the control whichever is less. 7. Prior to final acceptance by the City, haul roads and waterway crossings constructed for temporary contractor access must be removed, accumulated sediment removed from the waterway and the area restored to the original grade and revegetated. All land clearing debris shall be disposed of in approved spoil disposal sites. 8. All work must stop if a void in the rock substrate is discovered which is; one square foot in total area; blows air from within the substrate and/or consistently receives water during any rain event. At this time it is the responsibility of the Project Manager to immediately contact a City of Austin Environmental Inspector for further investigation. In addition, if the project site is located within the Edwards Aquifer, the Project Manager must notify the Travis County Balcones Canyonlands Conservation Preserve (BCCP) by email at bccp@traviscountytx.gov. Construction activities within 50 feet of the void must stop. 9. Temporary and Permanent Erosion Control: All disturbed areas shall be restored as noted below: A. All disturbed areas to be revegetated are required to place a minimum of six (6) inches of topsoil [see Standard Specification Item No. 601S.3(A)]. Do not add topsoil within the critical root zone of existing trees. • Topsoil salvaged from the existing site is encouraged for use, but it should meet the standards set forth in 601S. An owner/engineer may propose use of onsite salvaged topsoil which does not meet the criteria of Standard Specification 601S by providing a soil analysis and a written statement from a qualified professional in soils, landscape architecture, or agronomy indicating the onsite topsoil will provide an equivalent growth media and specifying what, if any, soil amendments are required. • Soil amendments shall be worked into the existing onsite topsoil with a disc or tiller to create a well-blended material. The vegetative stabilization of areas disturbed by construction shall be as follows: : TEMPORARY VEGETATIVE STABILIZATION: 1. From September 15 to March 1, seeding shall be with or include a cool season cover crop: (Western Wheatgrass ( Pascopyrum smithii ) at 5.6 pounds per acre, Oats ( Avena sativa ) at 4.0 pounds per acre, Cereal Rye Grain ( Secale cereale ) at 45 pounds per acre. Contractor must ensure that any seed application requiring a cool season cover crop does not utilize annual ryegrass ( Lolium multiflorum ) or perennial ryegra ss ( Lolium perenne ). Cool season cover crops are not permanent erosion control. 2. From March 2 to September 14, seeding shall be with hulled Bermuda at a rate of 45 pounds per acre or a native plant seed mix conforming to Item 604S or 609S. A. Fertilizer shall be applied only if warranted by a soil test and shall conform to Item No. 606S, Fertilizer. Fertilization should not occur when rainfall is expected or during slow plant growth or dormancy. Chemical fertilizer may not be applied in the Critical Water Quality Zone. B. Hydromulch shall comply with Table 1, below. C. Temporary erosion control shall be acceptable when the grass has grown at least 11⁄2 inches high with a minimum of 95% total coverage so that all areas of a site that rely on vegetation for temporary stabilization are uniformly vegetated, and provided there are no bare spots larger than 10 square feet. D. When required, native plant seeding shall comply with requirements of the City of Austin Environmental Criteria Manual, and Standard Specification 604S or 609S Table 1: Hydromulching for Temporary Vegetative Stabilization Material Description Longevity Typical Applications Application Rates 0—3 months Moderate slopes; from flat to 3:1 1,500 to 2,000 lbs per acre 70% or greater Wood/Straw 30% or less Paper or Natural Fibers 100% or any blend of wood, cellulose, straw, and/or cotton plant material (except no mulch shall exceed 30% paper) PERMANENT VEGETATIVE STABILIZATION: 1. From September 15 to March 1, seeding is considered to be temporary stabilization only. If cool season cover crops exist where permanent vegetative stabilization is desired, the grasses shall be mowed to a height of less than one-half (1⁄2) inch and the area shall be re-seeded in accordance with Table 2 below. Alternatively, the cool season cover crop can be mixed with Bermuda grass or native seed and installed together, understanding that germination of warm- season seed typically requires soil temperatures of 60 to 70 degrees. 2. From March 2 to September 14, seeding shall be with hulled Bermuda at a rate of 45 pounds per acre with a purity of 95% and a minimum pure live seed (PLS) of 0.83. Bermuda grass is a warm season grass and is considered permanent erosion control. Permanent vegetative stabilization can also be accomplished with a native plant seed mix conforming to Item 604S or 609S. A. Fertilizer use shall follow the recommendation of a soil test. See Item 606S, Fertilizer. Applications of fertilizer (and pesticide) on City-owned and managed property requires the yearly submittal of a Pesticide and Fertilizer Application Record, along with a current copy of the applicator's license. For current copy of the record template contact the City of Austin's IPM Coordinator. B. Hydromulch shall comply with Table 2, below. C. Water the seeded areas immediately after installation to achieve germination and a healthy stand of plants that can ultimately survive without supplemental water. Apply the water uniformly to the planted areas without causing displacement or erosion of the materials or soil. Maintain the seedbed in a moist condition favorable for plant growth. All watering shall comply with City Code Chapter 6-4 (Water Conservation), at rates and frequencies determined by a licensed irrigator or other qualified professional, and as allowed by the Austin Water Utility and current water restrictions and water conservation initiatives. D. Permanent erosion control shall be acceptable when the grass has grown at least 11⁄2 inches high with a minimum of 95 percent for the non-native mix, and 95 percent coverage for the native mix so that all areas of a site that rely on vegetation for stability must be uniformly vegetated, and provided there are no bare spots larger than 10 square feet. E. When required, native plant seeding shall comply with requirements of the City of Austin Environmental Criteria Manual, Items 604S and 609S. Table 2: Hydromulching for Permanent Vegetative Stabilization Material Description Longevity Typical Applications Application Rates Bonded Fiber Matrix (BFM) 80% Organic defibrated fibers 10% Tackifier 6 months On slopes up to 2:1 and erosive soil conditions 2,500 to 4,000 lbs per acre (see manufacturers recommendations) Fiber Reinforced Matrix (FRM) Up to 12 months On slopes up to 1:1 and erosive 65% Organic defibrated fibers 25% Reinforcing Fibers or less 10% Tackifier Soil conditions 3,000 to 4,500 lbs per acre (see manufacturers recommendations) 10. The contractor shall not dispose of surplus excavated material from the site without notifying the Development Services Department at 512-974-2278 at least 48 hours prior with the location and a copy of the permit issued to receive the material. REVISIONS / CORRECTIONS Number Description Revise (R) Add (A) Void (V) Sheet No.'s Total # of Sheets in Plan Set Net Change Imp. Cover (Sq-Ft) Date Imaged City of Austin Approval Date C. Where trees are close to proposed buildings, erect the fence to allow 6 to 10 feet of work space between the fence and the building; D. Where there are severe space constraints due to tract size, or other special requirements, contact the City Arborist at 974-1876 to discuss alternatives. Special Note: For the protection of natural areas, no exceptions to installing fences at the Limit of Construction line will be permitted. 7. Where any of the above exceptions result in a fence being closer than 4 feet to a tree trunk, protect the trunk with strapped-on planking to a height of 8 ft (or to the limits of lower branching) in addition to the reduced fencing provided. 8. Trees approved for removal shall be removed in a manner which does not impact trees to be preserved. 9. Any roots exposed by construction activity shall be pruned flush with the soil. Backfill root areas with good quality top soil as soon as possible. If exposed root areas are not backfilled within 2 days, cover them with organic material in a manner which reduces soil temperature and minimizes water loss due to evaporation. 10. Any trenching required for the installation of landscape irrigation shall be placed as far from existing tree trunks as possible. 11. No landscape topsoil dressing greater than 4 inches shall be permitted within the drip line of trees. No soil is permitted on the root flare of any tree. 12. Pruning to provide clearance for structures, vehicular traffic and equipment shall take place before damage occurs (ripping of branches, etc.). 13. All finished pruning shall be done according to recognized, approved standards of the industry (Reference the National Arborist Association Pruning Standards for Shade Trees available on request from the City Arborist). 14. Deviations from the above notes may be considered ordinance violations if there is substantial non-compliance or if a tree sustains damage as a result. APPENDIX P-4: - STANDARD SEQUENCE OF CONSTRUCTION The following sequence of construction shall be used for all development. The applicant is encouraged to provide any additional details appropriate for the particular development. 1. Temporary erosion and sedimentation controls are to be installed as indicated on the approved site plan or subdivision construction plan and in accordance with the Erosion Sedimentation Control Plan (ESC) and Stormwater Pollution Prevention Plan (SWPPP) that is required to be posted on the site. Install tree protection, initiate tree mitigation measures and conduct "Pre - Construction" tree fertilization (if applicable). 2.

All trees and natural areas shown on plan to be preserved shall be protected during construction with temporary fencing. 2. Protective fences shall be erected according to City of Austin Standards for Tree Protection. 3. Protective fences shall be installed prior to the start of any site preparation work (clearing, grubbing or grading), and shall be maintained throughout all phases of the construction project. 4. Erosion and sedimentation control barriers shall be installed or maintained in a manner which does not result in soil build-up within tree drip lines. 5. Protective fences shall surround the trees or group of trees, and will be located at the outermost limit of branches (drip line) , for natural areas, protective fences shall follow the Limit of Construction line, in order to prevent the following: A. Soil compaction in the root zone area resulting from vehicular traffic or storage of equipment or materials; B. Root zone disturbances due to grade changes (greater than 6 inches cut or fill), or trenching not reviewed and authorized by the City Arborist; C. Wounds to exposed roots, trunk or limbs by mechanical equipment; D. Other activities detrimental to trees such as chemical storage, cement truck cleaning, and fires. 6. Exceptions to installing fences at tree drip lines may be permitted in the following cases: A. Where there is to be an approved grade change, impermeable paving surface, tree well, or other such site development, erect the fence approximately 2 to 4 feet beyond the area disturbed; B. Where permeable paving is to be installed within a tree's drip line, erect the fence at the outer limits of the permeable paving area (prior to site grading so that this area is graded separately prior to paving installation to minimized root damage); NOTE: IF AT ANY TIME DURING C ONSTRUCTION OF THIS PROJECT AN UNDERGROUND STORAGE TANK (UST) IS FOUND, CONSTRUCTION IN THAT AREA MUST STOP UNTIL A CITY OF AUSTIN UST CONSTRUCTION PERMIT IS APPLIED FOR AND APPROVED. ANY UST REMOVAL WORK MUST BE CONDUCTED BY A UST CONTRACTOR THAT IS REGISTERED WITH THE TEXAS COMMISSION ON ENVIRONMENTAL QUALITY (TCEQ).

[COA TITLE 6] SITE APPENDIX P-6 - REMEDIAL TREE CARE NOTES AERATION AND SUPPLEMENTAL NUTRIENT REQUIREMENTS FOR TREES WITHIN CONSTRUCTION AREAS As a component of an effective remedial tree care program per Environmental Criteria Manual section 3.5.4, preserved trees within the limits of construction may require soil aeration and supplemental nutrients. Soil and/or foliar analysis should be used to determine the need for supplemental nutrients. The City Arborist may require these analyses as part of a comprehensive tree care plan. Soil pH shall be considered when determining the fertilization composition as soil pH influences the tree's ability to uptake nutrients from the soil. If analyses indicate the need for supplemental nutrients, then humate/nutrient solutions with mycorrh izae components are highly recommended. In addition, soil analysis may be needed to determine if organic material or beneficial microorganisms are needed to improve soil health. Materials and methods are to be approved by the City Arborist (512-974-1876) prior to application. The owner or general contractor shall select a fertilization contractor and ensure coordination with the City Arborist. Pre-construction treatment should be applied in the appropriate season, ideally the season preceding the proposed construction. Minimally, areas to be treated include the entire critical root zone of trees as depicted on the City approved plans. Treatment should include, but not limited to, fertilization, soil treatment, mulching, and proper pruning. Post-construction treatment should occur during final revegetation or as determined by a qualified arborist after construction. Construction activities often result in a reduction in soil macro and micro pores and an increase in soil bulk density. To ameliorate the degraded soil conditions, aeration via water and/or air injected into the soil is needed or by other methods as approved by the City Arborist. The proposed nutrient mix specifications and soil and/or foliar analysis results need to be provided to and approved by the City Arborist prior to application (Fax # 512-974-3010). Construction which will be completed in less than 90 days may use materials at 1⁄2 recommended rates. Alternative organic fertilizer materials are acceptable when approved by the City Arborist. Within 7 days after fertilization is performed, the contractor shall provide documentation of the work performed to the City Arborist, Planning and Development Review Department. P.O. Box 1088, Austin, TX 78767. This note should be referenced as item #1 in the Sequence of Construction.
