- 3 - II. SCOPE The purpose of this study is to determine the feasibility of rehabilitating the three roads mentioned above, along with any utility improvements and/or repair that may be needed prior to their proposed improvement. This report will include information on the existing conditions, proposed improvements, and estimated costs and property assessments as outlined in the City’s Assessment Manual. Estimated construction costs will be provided, along with the total project costs that will include overhead costs, such as City administration, engineering, fiscal, and legal costs. III. HISTORY The streets proposed for rehabilitation have received normal on-going maintenance from the City’s Public Works Staff, but are at a point that requires more extensive maintenance. The rehabilitation will allow for protection of the road base and concrete curb and gutter with improvement of the paved surface. This is the first time Demont Avenue and Morrison Avenue have been proposed for rehabilitation. Aspen Circle was proposed for rehabilitation in 2011. At that time the majority of property owners along this street segment indicated the improvement should be delayed. IV. NECESSITY AND COST-EFFECTIVENESS The three streets proposed for mill and overlay or pavement reclamation and repaving are within the range of 60 to 80, the rating that justifies rehabilitation. The street improvements are necessary to provide the residents of these areas with a safe and adequate public transportation system. The proposed improvements will protect the street base from water infiltration and further deterioration minimizing future maintenance costs, and the magnitude of the proposed project will ensure competitive bidding. From this standpoint, the project is cost-effective. V. EXISTING CONDITIONS A. ASPEN CIRCLE Aspen Circle was originally constructed in the mid 1980’s as an urban section. The street is approximately 1,220 feet long with a face-to-face width of approximately 30-feet. As with most developments a form of surmountable curb was used, but in the case of this street the surmountable curb slope is aggressive thereby providing for very abrupt driveway access. The street suffers from minor wheel track rutting, normal cracking, increasing alligator cracking, spalling and raveling of the pavement, and failure of previously patched areas. The concrete curb and gutter is in good condition, but as mentioned above has a very aggressive profile for surmountable curb. To protect the street from more advanced base deterioration a surface rehabilitation is recommended. All abutting properties are served with sanitary sewer and water. In addition, an existing storm sewer system serves the street.
