Preliminary Scope of Work Existing infrastructure conditions within the proposed project area are as follows: • Streets o Current pavement condition rating is 31 out of a possible score of 100. The surface of the streets is in poor condition covered in an extensive amount of cracking. These streets have seen an increase in needs for pothole filling and patching, therefore increasing the cost to maintain. o Core samples from the Pavement Forensic Report resulted in varied conditions from good to poor but ultimately a majority of the cores were showing signs of deterioration. • Sanitary o Sewer was installed in 1982 as part of the residential development. 8-inch PVC material was used, and through televising reports, it is in good condition. o Manhole castings and concrete rings are deteriorating and need repair. • Water o Water main was installed in 1982 as part of the residential development. 6-inch ductile iron pipe was used and this area shows no history of main breaks. • Storm Drainage o Storm catch basin structures are deteriorating and need repair. o Storm sewer pipe needs to be televised to report condition. o Curb and gutter are generally in good condition but spot replacement is needed in some areas. o The southern curb line along Arden Oaks Drive off Snelling Ave to the cul-de-sac has a noticeable sag, indicating poor subsurface drainage or in need of soil correction. Additional research regarding the age and condition of existing infrastructure will be evaluated during preparation of the feasibility report. Based on the previous information stated, staff anticipates the project will include the following elements: ■ Arden Oaks Drive (From Snelling east 400 feet including cul-de-sac): Full-depth reconstruction of streets with installation of curb, gutter and storm sewer, producing a street width of 32 feet. Existing ductile iron water main and PVC sanitary sewer to remain in-place. ■ Arden Oaks Drive (Remainder): Full-depth reclamation of existing pavement, and placement of new 4-inch bituminous pavement mat, spot repair of damaged curb sections, repair or replace storm structures. Existing ductile iron water main and PVC sanitary sewer to remain in- place. ■ Arden Oaks Circle: Full-depth reclamation of existing pavement, and placement of new 4-inch bituminous pavement mat, spot repair of damaged curb sections, repair or replace storm structures. Existing ductile iron water main and PVC sanitary sewer to remain in-place. Preliminary Project Budget The cost estimate was derived from the above anticipated project elements listed. The initial cost estimate is summarized in the following table and will be revised as part of the feasibility report. Page 2 of 4
