3. EXISTING CONDITIONS 3.1 Existing Streets 3.1.a Regency Pond Residential Neighborhood The existing right-of-ways along the street segments proposed to receive overlays as part of this project are 60-feet in width. The paved street width is 30-feet as measured from curb to curb. All streets in this project were constructed as urban sections with bituminous pavement and concrete curb and gutter between 1996 and 1998. The streets segments proposed to receive overlays in 2020 have 2018 PASER ratings between 6 and 8, which are generally considered to be good candidates for mill and overlay improvements. To verify that the pavement sections were thick enough and had adequate structural capacity to support 2-inch mill and overlay improvements, Staff hired WSB and Associates to complete a pavement forensics analysis, which included the extraction of pavement cores from each street segment proposed to receive mill and overlay improvements. The pavement forensics report is included in Appendix D of this report. Based on the general condition and thickness of the existing pavement sections, WSB and Associates and City Staff do not recommend completing mill and overlay improvements on these street segments as proposed. It is estimated that the existing streets should remain serviceable with moderate maintenance for up to 10 years. Once PASER ratings fall to 3 or less, a full -depth reclamation (FDR) or reconstruction project should be completed. 3.1.b Business Park 95 Industrial Park The existing right-of-ways along the street segments proposed to receive overlays as part of this project range from 66 to 80-feet in width. The paved street widths range from 38 to 44-feet as measured from curb to curb. All streets in this project were constructed as urban sections with bituminous pavement and concrete curb and gutter between 1995 and 1998. The streets segments proposed to receive overlays in 2020 have 2018 PASER ratings between 6 and 7, which are generally considered to be good candidates for mill and overlay improvements. To verify that the pavement sections were thick enough and had adequate structural capacity to support 2-inch mill and overlay improvements, Staff hired WSB and Associates to complete a pavement forensics analysis, which included the extraction of pavement cores from each street segment proposed to receive mill and overlay improvements.
