III. EXISTING CONDITIONS A. Streets The streets within the proposed project area are all local residential streets with urban street sections consisting of bituminous pavement and B618 concrete curb and gutter. The roadways provide a drive lane in each direction and parking along most, but not all, curb lines. No parking is allowed along the eastern curb line of Royal Lane adjacent to Floral Park. City records show the roadways were constructed primarily in the 1970's and 1980's with varying levels of maintenance being completed since then. Table 1 below shows the existing street widths from face of curb to face of curb, approximate right-of-way widths, and the Overall Condition Index (OCI) of the pavements from a 2023 City inspection.

The bituminous pavement within the study area exhibits wear and distress due to traffic loading as well as typical weathering effects experienced with aged asphalt pavement. The existing pavement contains surface delamination, transverse cracking, longitudinal cracking, some potholing, and some alligator -type cracking. Alligator cracking in pavement is an indicator of potential subgrade problems. Soil borings and a geotechnical evaluation were completed in the project area by Braun Intertec and the report is included in Appendix E. The existing bituminous pavement thickness ranges from 3.5 to 4 inches with an aggregate base thickness range from 6 to 7 inches. Existing subgrade soils found beneath the aggregate base are predominantly loose to medium dense sandy soils. Prepared by: Bolton & Menk, Inc.
