We have also identified a number of options for Council to consider and provide further direction to staff. Based upon the existing roadway pavement conditions and lack of curb and gutter and drainage the proposed improvements include reconstruction of Siems Court, Ridgewood Road, Arden Place and Skiles Lane. Ridgewood Court could be reconstructed with the remainder of the neighborhood, however the condition and characteristics of this street arc significantly different from the other neighborhood streets and should be cousidered separately for inclusion or exclusion from the project. RIDGE WOOD COURT DISCI!SSIOI'i Ridgewood Court is approximately 700 feet long and 12 feet wide. The existing ROW is approximately 20 feet. It was overlayed in 1996 and has a PCI rating of 91 (2002) and appears to be in good condition. There is bituminous curb along both sides of the road to limit runoff from flowing into private propeliy. The majority of runoff flows along the bituminous curb to Ridgewood Road, although dUling large storm events, mnoff enters several pri vate properties via driveways. At the southem end of the road, the runoff flows over the edge of the cul-de-sac, down a riprap swale and through pri vate property to an area drain. The area drain is connected to a PVC pipe that runs under Arden Place and outlets directly into Lake Johanna. The existing runoff from the cul-de-sac flows overland down a steep slope and into private propeliy. Residents have expressed concern over this and the City is required to maintain the slope from erosion problems. If Ridgewood Court is not reconstructed at this time and requires reconstruction prior to the remainder of the neighborhood (within the next 20 years), the work could be accomplished with minimal disturbance to neighborhood streets. Ridgewood Court Option 1: Leave Ridgewood Court As Is. The roadway section doesn't meet City standard, however it has a high PCI ranking and the existing bituminous curb appears to be functioning reasonable well. This option is the recommendation of staff. Ridgewood Court Option 2: Reconstruct Ridgewood Court, The full removal and reconstruction of Ridgewood COUli would cost approximately $120,000. This includes the construction of concrete curb and gutter with driveway aprons to keep runoff in roadway and all flow would be collected in the storm sewer system along Ridgewood Road. Storm sewer would be constructed at the southem end of the cul-de-sac and constructed through backyards to Arden Place, as exists today. The drainage work could be completed without the reconstruction of the roadway. Refer to Ridgewood Couli drainage improvement options later on in report. I!RS 6
