The proposed PARD Duct Bank Project is to include a new duct bank segment along a route through the City of Austin parkland parcel #190751 which is located adjacent to Lady Bird Lake just south of the Four Seasons Hotel. This route is proposed to start at an electric manhole to be installed by the Waterloo Greenway - Creek Delta project in the vicinity of the Austin Rowing Club/Alta's Cafe. The electric duct bank is proposed to be bored via microtunneling following a parallel path to the Lady Bird Lake shoreline between the existing electric manhole located at the cul-de-sac on Brazos St, south of Cesar Chavez and the new manhole by the Boathouse. It is currently estimated that approximately 900 linear feet of duct bank will be installed. The duct bank will comprise of a qty 9-5" conduit design with 6 ft x 12 ft electric manholes installed no deeper than 20 ft below existing grade on each end. New electrical manholes will be installed on each end and tie-ins to existing electrical manholes will be required to connect the electrical duct bank network. This installation is part of Austin Energy's downtown distribution energy plan to connect the new Rainey St. substation to provide a more resilient energy system. A summary of the investigational findings pertinent to the project are as follows: 1. Seven (7) borings, BH-1 through BH-7 were drilled to the depth of 60 feet each to investigate stratigraphy and to obtain samples for laboratory testing for total of 420 feet drilled. Four (4) borings (BH-1 through BH-4) were drilled during initial phase of the project and three (3) additional borings (BH-5 through BH-7) were drilled along the Lady Bird Lake shoreline. 2. In general, soil conditions encountered at the project site consist of Alluvium (Qal), Lower Colorado River Terrace Deposits (Qlcr) overlaying Weathered Limestone of the Austin Group (Kau). However, Eagle Ford Shale (Kef) was encountered in Borings BH-2, BH-3, and BH-5 at 31.5 feet, 41 feet and 50.75 feet, respectively below surface. Fill soils were encountered in borings BH-1, BH-5, BH-6, and BH-7 from the surface grade to the depths of 5 to 6 feet and were classified as Clayey Sand with Gravel (SC), Lean Clay (CL) and Sandy Fat Clay (CH) with various amounts of gravel and sand. Borings BH-2 and BH-3 encountered Alluvium Soils consisting of Sandy Silt (ML), Lean Clay with varying amount of sand from existing surface to a depth of 12 to 19 feet. In borings BH-1, BH-2, and BH-4 through BH-7, Lower Colorado River Terrace Deposits generally consisted of sand and gravel with various amount of clay and silt content (SC, SP, GW-GM, GC, GP, GP-GM, GW-GC), and Sandy Lean Clay (CL) below existing surface and fill material extending to a depth of 16.25 to 28.5 feet. Limestone of the Austin Group (Kau) was encountered in borings BH-1 through BH-7 at depths ranging from about 16.25 to 28.5 feet below existing grades underlying the Lower Colorado River Terrace deposits. It was found to be grayish white and tan to gray, low hardness to moderately hard and highly to moderately weathered with interbedded clay and bentonite layers/seams. Eagle Ford Shale (Kef) was encountered in Borings BH-2, BH-3, and BH-5 at 31.5 feet, 41 feet and 50.75 feet, respectively below surface. The coring recovery (for limestone and shale) ranged from 82% - 100%, the rock quality designation (RQD) ranged from 0 - 97% and the unconfined compressive strength (UC) ranged from 125 - 3439 psi. 3. Groundwater was encountered during drilling in borings BH-1 through BH-7 from depths of 4.5 to 27.3 feet below the existing surface grades. It should be noted that groundwater levels may fluctuate seasonally in response to climatic conditions. Groundwater may also exist in a perched condition at the interface of soil and bedrock surface. Additionally, groundwater level along the project alignment is anticipated to be influenced by the water level of Lady Bird Lake. 4. Borings BH-1 and BH-7 were drilled through the existing pavement structure, consisting of 2 to 8 inches of asphaltic concrete over 6 to 16 inches of pavement base material. 5. During Packer tests, no water loss was observed within the test zones for boring BH-7 and between 50 and 60 feet of boring BH-5. For the test conducted in BH-5 from 33 to 60 feet, estimated average permeability values are 1.69x10-3 ft/min (8.58x10-4 cm/sec) and 1.67x10-3 ft/min (8.46x10-4 cm/sec) for 5 and 10 psi pressure, respectively. Objectives and Scope of Work The primary objective of this study was to gather information on the subsurface conditions at certain locations within the area of the proposed project. This objective was accomplished by: Task 1: Exploratory Borings and Piezometer Installation Drilling 7 borings to depth 60 feet each to investigate stratigraphy and to obtain samples for laboratory testing. Installation of a piezometer at BH-1 location. Task 2: Packer Testing Conducting packer testing at two (2) boring locations (i.e., BH-5 and BH-7) to estimate in-situ permeability of the rock mass. o Task 3: Laboratory Testing Performing laboratory tests on select soil samples to determine the physical and engineering properties of the subsurface materials. o Task 4: Data Report Characterizing the subsurface conditions and reporting the results.
