LB 44 GARLAND, TEXAS 75042 TEXAS REGISTRATION F-12266 BASELINE DATA COLLECTION AND ANALYSIS The site is proposed to be developed as a Discount Tire Store (DTS) on a 1.38-acre proposed Lot 11, Block 1 of the Vista Crossroads Addition in Fort Worth, Texas. It is generally located 1700 feet southeast of the intersection of U.S. Highway 287 (U.S. 81) and Avondale-Haslet Road on the northern side of the northbound service road of U.S. 287. The developer proposes to construct a commercial building with associated parking areas, detention pond and a crossing of a road side channel. The development of an on-site detention pond is the selected method for the flood mitigation option. This is per Option 2 provided in Section 3.7.2 of the City of Fort Worth Stormwater Criteria Manual. Two other iSWM plans are under development by others for the site area including: 1)the Vista Crossroads Addition improvements (for the entire subdivision) by Teague Nall & Perkins, and, 2)the Taco Bell development being prepared by Dunaway. The proposed Taco Bell site is located northwest and adjacent to the DTS in Lot 10 of the Vista Roads Addition. The following information is for the proposed Discount Tire site. Topography Existing topography is relatively flat grassland sloping approximately 1% from north to south. Existing contour data was surveyed by Peiser& Mankin Surveying, LLC and can be viewed on the design plans. Drainage Patterns and Basins The site is in the Indian Creek— Eagle Mountain Lake watershed that drains to Eagle Mountain Lake with the receiving waters being the Upper West Fork of the Trinity River. The local drainage pattern is from north to south where storm water flow enters a 36" rcp through an existing headwall. Storm water is conveyed northeasterly in a series of pipes under the northbound service road. The design of this storm water system was prepared by Halff Associates as part of the US 287/81 roadway plans. The TXDOT plans were prepared under Control No. 1600, Secion 15, Job No. 032. The proposed development of the Taco Bell by Dunaway includes construction of an open conveyance channel along the southerly side of the DTS site along with an inlet and connection pipe to the existing 36" rcp in the service lane. The Taco Bell development will include a detention pond and outlet that flows into the open channel. There are no intermittent or perennial streams on-site. Soil Types Soil types in the upper limits of the site are CH clay to approximately two feet deep where limestone layers intermixed with clays can be found. The soils are considered erosive and will be maintained through cover vegetation on the soils and by pavement and structures that offer more permanent solutions. Ground Cover and Vegetation The ground is covered with native grasses. There are no particularly unique or sensitive vegetation areas to be protected during development. Existing development The site is currently undeveloped. There is a retail development anchored by a Walmart store approximately 120 feet north and west of the site. Undeveloped, agricultural land is located east, south, and west of the site across U.S. 287. Existing Storm Water Facilities There are no existing storm water facilities on-site. However, an earthen channel will be constructed across the south side of the site as part of the development of a new Taco Bell restaurant immediately northwest of the site. The Taco Bell has been proposed on Lot 10, Block 1 of the Vista Crossroads Addition. Off-site storm water facilities that will receive discharges from the proposed development include the open channel and an existing reinforced concrete pipe parallel to the site boundary along U.S. 287. Property Lines The site property lines, adjacent owners and local easements are show on the proposed plans. This data is based on surveys prepared by Peiser& Mankin Surveying, LLC described in the plans. Wetlands and Critical Habitat Areas There are no know wetlands, Waters of the United States, or critical habitat areas located on the site. Wooded Areas There are no wooded areas or trees clusters located on the site. Floodplain Boundaries There are no regulatory floodplain boundaries located within the site. The site and surrounding area can be reviewed on FEMA FIRM panel number 48439C0035K dated September 25, 20019. Steep Slopes There are no steep slopes located on the site. Buffers and Setbacks There are no required buffers or setbacks along any water bodies. Stream Crossings There are no proposed stream crossings. The proposed conveyance channel along the service road of S.H. 187 will be crossed by a sidewalk as part of the Discount Tire Store detention pond development. There are no other know required protection areas. Site Plan The Site Plan is provided in the plans and is labeled SP1. Pre-development Aerial Photo with Composite Impervious Area Calculations Sheet C3.0 of the design plans includes the pre-development plan for the watershed sub-basin with an aerial photograph and calculations. Drainage Area Map Sheets C3.1 provides the site drainage area maps and calculations for the pre-developed and post-developed conditions. Simplified Methods Utilized and Documentation Provided The development of an on-site detention pond is the selected method for the flood mitigation option. This is per Option 2 provided in Section 3.7.2 of the City of Fort Worth Stormwater Criteria Manual. The detention calculations are provided on sheet 3.2 of the design plans. The detention pond was calculated using the Modified Rational Method described in Section 1.5 of the Hydrology Manual. The spreadsheets provided on sheet 3.2 are the non-iterative spreadsheet calculations developed by Debo & Reese in 2003. Detention pond volumes along with the Orifice Calculations for the outlet structure are provided for the 1, 10, and 100-year storms on sheet C3.2. The Outlet Structure Detail is provided on sheet 3.1. Storm water flows to an existing system designed by Halff Associates as part of the highway design. The detention calculations include the pass-through of the Taco Bell site per the Dunaway design and the information is provided on sheet 3.2 of the design plans. A schematic plan of the detention basin is provided on the following page. The proposed Landscape plans are provided on the following pages along with selected site design plans. e J J Q p O Q W n p _ � W ~ Q� J O W -i CD O WJ W r �1 1 Q Ci a w v v O co S co if ti, lJ �1bM341S J 11 = Q g O LL- C14 O J ai Q O W co O J w O w LU cq co W M o °° t) K1 p n J a a IL J p cn w J J W Of CO J W O � W 3daH.8 Q S m Q Z Z z z O o °o°o 22 O y ^ m Lll or'o9 3: - z `�- _ z 11 co LL w F- C) z cn m L1J W O Z Z a w Nl dM3aIS � J z m w m w it a w a W g W z v ar J 0 C ir o a a O W a pop J U 3 o w o U) co O f- �o _ p yr to p �I WLLI-i•uay•E•tl xi BYX31 141AMM jhKX r �- m X111 »In 0M 9 wwwsls�sble/ -0'1-7 ONIN33NION3.Z.M YA 6 E Ip � Q a a bbe • I I , $ R R`R aA �y pp3 • � E �y � � c.@i!b - �9 s A s a o , �gaaEa g 6 a 1 , -` a 8 i i t 1` .\I\ 1 %rill _ VIII II 4.9 a� II •s v ��.a�w S x. � ' C b4 54 II g i or ss 9 19 �IIIR I � I I I El I e s � �� - x 4' I I• III /' 1 i 1 _ I I fill / 1 _ 34 � ocuzlaa n••ieM � O —� 1 ON 44 m .' �p r ow Ati 4��I 1 ®1 '; do �/ 4 fit ?I 9 I} � s ■ 2g �i VASQUE2 ENGINEERING LLC. f 1010 S.$Nall Itaa • T1RE a T�� wzz✓a ouca".+a,u SvxaL 14HOM J!!D� erez-eL V u r� •a�•��Nw�NIO�zanosvw 6 � ° e 03 f f E !!

NON-ROUTINE MAINTENANCE SPECIFICATIONS Non-routine items that may require attention include the following: A. Bank Repair and Stabilization: To be performed quarterly. Side slopes and top of banks shall be examined quarterly for sloughing or erosion of the soils. Areas requiring attention shall be regraded, compacted and reseeded or sodded to provide appropriate grass cover. B. Re-vegetation: To be inspected quarterly. Area where vegetation has eroded or died shall be regraded, compacted and reseeded or sodded to provide appropriate grass cover. C. Sediment Removal: To be inspected quarterly. Sediment shall be removed from the pond if it reaches a depth of 5" above bottom grade. The sediment shall be removed, the area will be regraded, and be reseeded or sodded to provide appropriate grass cover. D. Structural Repair: To be inspected quarterly. The outlet structure, the rock rip rap structures, and the sloped headwalls shall be inspected for cracks, failure, or sloughing. They shall be repaired as required to perform as designed. E.
