Prepared by: Bolton & Menk, Inc. WOODLYNN AVENUE 2022 Street & Utility Improvements (Woodlynn Ave, Ryan Dr) ǀ 0N1.125241 Page 7 III. WOODLYNN AVENUE Background Woodlynn Avenue is a city street that serves industrial uses. West of the railroad, it has an urban section with curb and gutter. East of the railroad, it has a rural section without curb and gutter. Annual average daily traffic (AADT) data for this road is unavailable but assumed to be less than 1,000 vehicles per day, classifying it as a low-volume road. Refer to Figure 1 in Appendix A for a depiction of the project location. Woodlynn Avenue was constructed in 1977. Watermain was installed in 1986 to serve the properties; portions of the street were re-paved as part of that project. Since then, the street has received pavement management treatments including to prolong the life of the pavement. Annual patching and utility infrastructure maintenance has also been performed on an as- needed basis. Existing Conditions 1. Streets Woodlynn Avenue is a bituminous roadway bisected by the railroad into two distinct segments. The west portion of Woodlynn Avenue has a width of 26 feet from face of curb to face of curb. Concrete curb & gutter on both sides of the street channel surface runoff west towards Rice Street. Pavement in this half shows early signs of wear and distress including some cracking and pavement oxidation. The east portion of Woodlynn Avenue has a variable width averaging 30 feet from its bituminous edges, with no curb & gutter. The pavement in this portion project area shows significant wear and distress, as indicated by pavement oxidation, cracking, raveling, and potholes. A geotechnical investigation was performed by Braun Intertec. The investigation found that the existing pavement section includes 3 to 4 inches of bituminous pavement and 3 to 8 inches of aggregate base. 2. Watermain The existing watermain is an 8- inch diameter ductile iron pipe extending east from Rice Street and terminating at the street’s easternmost fire hydrant. Refer to Figure 2C in Appendix A for a depiction of the existing utility infrastructure. The watermain has performed well with no known deficiencies. Based upon the age, type, and positive performance of the watermain, the useful life of the system is anticipated to outlast the pavement improvements described in this report. 3. Sanitary Sewer The existing sanitary sewer east of the railroad is a combination of PVC and vitrified clay pipe gravity sewer and cast-iron pressurized force main that conveys wastewater west across the railroad tracks to a sanitary collector line. The pressurized portion of the sanitary sewer system is fed by a lift station located in series with the system. Exhibit 3 – Existing Woodlynn Avenue (East)
