AWC conducted a physical inspection of 15TH Street and the surrounding area. During this inspection a significant amount of physical damage was observed. The road is failing in multiple places, numerous potholes have formed and been patched creating a bumpy and uneven surface. This is especially the case for the North-East end of 15TH Street where it adjoins Main Avenue. All damage to the street was recorded and with a digital camera attached to an aerial drone. AWC employees used the drone to fly over the entire project site and gather current aerial photographs of the area. This information was used to create three unique pavement designs. As a result of our analysis of the current condition of the road as well as the three different pavement designs, it is our recommendation to utilize Option 1 (concrete roadway with open ditches). We anticipate that Option 1 will provide the most benefits considering construction cost and overall life expectancy of the roadway. A construction cost analysis shows that Option 1 will cost approximately $201,968.80. 1 • ti IntroductiAl on ..

The Northeast end of 15TH Street is perpendicular to Main Avenue and the Southwest end is connected to Vera Drive. AWC has completed a topographic survey and traffic observation of the entire project area. During the traffic observation it was noted that the roadway is utilized by residential traffic and no heavy truck traffic was observed. A three-step approach was used to complete the 30% design phase of this project. The steps are defined as follows: 1. Research and Review 2. Field Inspection 3. Preliminary Design 3.0 RESEARCH AND REVIEW: The research and review portion of this project consisted of gathering all relevant information for the project location that was available. This involved reviewing CPA maps to determine the extent of utility services in the project vicinity. The CPA water utilities map detailing the location of domestic water lines shows that there are no water lines located on 15TH Street. However, there is a single 6-inch water line located on Main Avenue and a single 8-inch water line located on Vera Drive. The CPA sanitary sewer and storm sewer utility maps also indicated that there are no sanitary or storm sewer lines located beneath 15TH Street. CPA Water Utilities personnel were contacted, and they confirmed that the maps provide an accurate description of the current utilities located beneath and in the vicinity of 15TH Street. The firm performed an "811" locate for existing utilities during this phase of the 2 AO% mic 'AI L' .' project. To best understand the soil composition in the project area a Geotechnical Report was provided by T&N Laboratories and Engineering. This Geotechnical Report contained recommendations for strengthening the soil as well as providing minimum specifications on which to base the different pavement designs. The Geotechnical Report is included in Appendix "A" of this report. 4.0 FIELD INSPECTION: To collect as much physical information as possible, AWC conducted a detailed field inspection of the project site on May 22, 2018. This inspection involved walking through the entire project site and getting a firsthand account of the current condition of the road. A large amount of damage was documented during the walk through and is discussed in greater detail in the design portion of this report. A drone was utilized to gather aerial photographs of the project site. These photos provide a current overall view of the whole street and the surrounding areas. Topographic survey and boundary information was also collected for the entire site. 5.0 PRELIMINARY DESIGN: The design portion of this report will encompass the processes and methodology used to create different design options. To mitigate the existing physical damage to 15TH Street, three different design scenarios were evaluated. In each case the roadway section selected was 24-feet wide per CPA standards. However, due to the physical constraints imposed by the existing roadside ditches, a 24-foot wide road would require the ditches to be relocated. In the event that the City would like to avoid the relocation of the existing roadside ditches, AWC investigated what changes this would 3 AD% ermic v.)). warrant to the current design. The existing roadside ditches can remain in their current location by using a 22-foot wide roadway. A 22-foot wide roadway would of course require that a variance be made to the City's design standards. The three different roadway designs included two separate asphalt road options as well as a concrete roadway option. One of the asphalt road designs includes removing the existing open ditches running parallel to 15TH Street and replacing them with a storm sewer system. The three different design scenarios were categorized as follows. 1. Option 1: Concrete pavement with open ditches 2. Option 2: Asphalt pavement with open ditches 3. Option 3: Asphalt pavement with concrete curb and gutter The paving sections and cost estimates were based upon recommendations in Geotechnical Report No. 18063 by T&N Laboratories and Engineering in Appendix "A" of this report. The project storm runoff was also analyzed for a 25-year storm event in a drainage analysis program to size the underground storm sewer for Option 3. During this analysis it was determined that Option 3 is not a feasible alternative. Option 3 is attractive in that it would eliminate the roadside ditches. However, the current elevation of the roads will not allow enough cover for storm pipe. All three roadway design options were analyzed for constructability, cost and life expectancy. For constructability AWC researched all existing conditions and utilities to mitigate any potential conflicts during design and construction. The estimated cost of construction for each option is based upon a compilation of average bid prices that we regularly update and have received on local roadway projects over the last 10 years. The life expectancy of the roadway is based upon the average life of each roadway section design and the physical traffic observation. 4 11 Existing Conditions y . fm. .. ARCENEAUX WILSON &COLE engineering I surveying I planning a IA 6.0 EXISTING CONDITIONS: The existing condition of the asphalt roadway is in poor condition with many base failures resulting in potholes and a large amount of the asphalt driving surface has completely deteriorated. The majority of the base failure areas are located near the intersection of Main Avenue, but they continue along the entire roadway and affect approximately 80% of the roadway surface. The deteriorated driving surface is mainly located on the southern edge of the roadway for the entire length of the road. • -�.} .. .114, awvc .A1 4 • • • 4 y��•_ ..•r y_y.,.,-.1• y+�--cry. ` _. - I.•Svc' - • ;rr ri ': ;1 5 z • rau p,s 6 z.. ox .. :. ;,_„._ , . .0, ,::..,..,_ .....1.,. . _ • • CeLrt....... q ...,..,. ., ,....4,,.,..„4. ...,..,....„...,...,,,, ,..,,,.......,......„...,;: ....„„,T ,� . 3 moyW�e, •.t ..14� .�,•, rd, > :. 1. rte. • ., ... ., .;�-:�-� _.. ..:.

Report Date: May 29,2018 Project No.: 18063 Job No.: 80947 INTRODUCTION/SYNOPSIS: Presented herein are the results of our geotechnical study with subgrade and paving design recommendations for the above-referenced project. Our subsurface study was authorized by Mr. Derek Graffagnino. The subsurface investigation was performed on May 21,2018 in general accordance with standard procedures for drilling, sampling and laboratory testing of subsurface soils for roadway development. Engineer of Record for this report is Jack C. Lind, P.E. - Texas Registration No. 79555. PROJECT DEVELOPMENT: This project will involve reconstruction of"15th Street in Port Arthur, Texas". Engineering design recommendations will be discussed in this report. -1- SCOPE OF STUDY: The objective of our study was to explore surface materials and subsurface soils conditions in the proposed reconstruction areas and formulate geotechnical design criteria for subgrade and paving designs. Our subsurface study included the following: 1) Drill test borings in two (2) selected locations; explore groundwater&geological conditions and collect soil samples for laboratory testing. 2) Perform a laboratory testing program on selected soil samples to evaluate physical and engineering properties on the subsurface soils. 3) Prepare and promulgate engineering analysis to provide geotechnical design and construction recommendations associated with: a) subgrade preparation for pavement, b) paving design criteria for flexible pavement SITE EXPLORATION: T&N was authorized to drill two (2) soil borings to depths of four ft. (4') below existing ground surface at locations selected by the client. Our exploration was accomplished with a buggy-mounted rotary drilling rig. Locations of the borings are stated on the "Boring Logs" included within the "ILLUSTRATIONS" section of this report. SOIL SAMPLING: Soil samples were secured continuously from ground surface to the four ft. (4') depth. Cohesive samples were obtained by hydraulically pushing a Shelby tube sampler a distance of about two ft. (2'). Our field sampling procedure was conducted in general accordance with provisions outlined in "Standard Practice for Thin-Walled Tube Sampling of Soils— (ASTM D1587)". -2- Soil samples were collected in the field and visually classified by our geotechnician. The geo- technician measured penetration resistance of recovered soil samples using a pocket penetrometer. Measured penetration resistance is shown on the "Boring Logs" and was used to estimate soil consistency. Representative portions, of each recovered soil sample, were sealed and placed into containers;then transported to our laboratory for testing and engineering study. GROUNDWATER CONDITIONS: Borings were drilled "dry" utilizing flight augers and soil samplers. Groundwater was not encountered in the borings during drilling operations. Groundwater is likely to fluctuate in upper strata during seasonal climatic changes. Water levels measured in open boreholes may not accurately reflect true groundwater conditions and should be considered only as approximate indications for this report. LABORATORY TESTING PROGRAM: Our Laboratory testing program was performed primarily For soil classification and evaluation. The following tests procedures were utilized in laboratory: Testing Performed Test Procedure Atterberg Limits (LL & PI) ASTM---D4318 Natural Water Content (%) ASTM - D2216 Unconfined Compression Test (UCS) ASTM—D2166 Percent(%)Passing#200 Sieve ASTM—D1140 Shelby Tube Samplers ASTM - D1587 Soils Classification ASTM—D2487 Results of these tests are shown on the "Boring Logs". -3- SUBSURFACE CONDITIONS: The particular subsurface stratigraphy,as determined from our field and laboratory programs, is shown in detail on the "Boring Logs". A review of these logs indicates that surface course materials consisted of seven to eleven in. (7"— 11") of asphalt underlain with a limestone base. Below the surface course, the soils along this portion of roadway are typically"high plastic clay" to four ft. (4') depth. The soils exhibit a relatively uniform moisture content, with moisture contents ranging from 24%to 27%with an average shear strength of about 1275 psf.. ANALYSIS AND DISCUSSION: The following analysis is based on data obtained from our field and laboratory test programs,project information provided to us and our experience with similar subsurface and site conditions. The paving designs considered in this report include; (1) milling surface asphalt, and underlying limestone base to a depth of seven to eleven in. (7"- 11") and compacting. After initial subgrade preparation, the proposed surface course can be placed, or(2) milling surface course as described above,removing and stockpiling milled material, stabilizing subgrade with lime, then replacing milled material and compacting. In lieu of using the milled material in Option 2, new limestone base could be placed and compacted, and the existing surface course can be removed and discarded. Design recommendations are based on typical CBR Values, related to normal vehicle traffic. Some areas of the roadway will only receive an asphalt overlay. SITE PREPARATION: The surface asphalt and shell base may be milled to about a seven to eleven in. (7"- 11") depth. For Option 1, once this material has been thoroughly milled and mixed, it should be moisture conditioned and compacted to at least 95%of the maximum density (ASTM D698) at the optimum moisture content,plus or minus 3%. If Option 2 is selected, either the existing surface course can be milled and stockpiled for later use,or it can be removed and discarded, and new limestone base can be used. With either material,the subgrade should be stabilized with approximately 6% lime by weight to a depth of six to eight in. (6"- 8"). After stabilization, the material should be moisture conditioned and compacted to at least 95% of maximum density at the optimum moisture content,plus 3%of minus 2%. -4- PAVEMENT SUBGRADE: Our laboratory data indicate the upper soils classify as"Active Clay (CH)" by the Unified Soil Classification System. This soil would have a subgrade modulus, k, on the order of 110 to 150 pci and CBR Value on the order of 2 to 6. Based on correlations of subgrade type and supporting capacity, the required pavement thickness as a function of wheel loading for flexible paving, using conventional structural fill or base course material, is discussed in the following sections in this report. These pavement sections will be suitable for frequent applications of design wheel loading and infrequent loads of greater magnitude. Adequate subgrade drainage is necessary to pavement performance in accordance with design criteria. FLEXIBLE PAVEMENT DESIGN: If needed,overlay the prepared and compacted milled surface with suitable flexible base TXDOT Item 247 Type-A, Grade 1, or equal; then place two inches (2") of Type"D"HMAC pavement surface. Reference: TXDOT Item 340. The HMAC mix designs for job mix formulas should be prepared and submitted by qualified testing laboratory experienced in TXDOT 340 Design Methods. STRUCTURAL & SELECT FILL MATERIALS: If needed, select fill should be homogeneous soil, free of organic matter and rocks larger than two inches (2") in diameter. Select fill should have an "Atterberg Plasticity Index"between eight and twenty(8—20), with a "Liquid Limit"of forty(40) or less. Delivered fill materials should have a moisture content no greater than six percent(6%) above optimum. -5- DRAINAGE: The importance of drainage to the proper operation and function of any pavement cannot be overemphasized. The pavement and subgrade surface should be raised above adjacent grade, if practical and properly sloped into drainage inlets or lateral ditches. Water should not be allowed to stand on/or adjacent to the pavement whereby the subgrade may become saturated. If the pavement sublayers do become saturated, the bearing capacity will be greatly reduced and the useful life of the pavement will be decreased. Periodic inspections and repair of cracks in pavement sections should be performed as a part of future facility maintenance. All grades must be adjusted to provide positive drainage away from the structure. Where paving or flatwork abuts the structure,care should be taken to insure joint is properly sealed. QUALITY CONTROL: Construction inspection with field quality control tests should be planned and performed to verify materials and placement in accordance with the project requirements. In-place density tests, HMAC production and concrete strength quality should be maintained during construction. T&N Laboratories & Engineering will be pleased to provide these services and will assist with the inspection,planning and scheduling for Quality Control Testing, etc. with documented reports for permanent records. T&N Laboratories & Engineering maintains "state-of-the-art" lab and field test equipment for these types of services. -6- LIMITATIONS: The report writer warrants that findings, conclusions, specifications or professional advice contained herein have been promulgated after being prepared in accordance with generally accepted practice in the field of foundation engineering and material test evaluation.
