Newell, P.E., City Engineer ,,,,� W�.-- SUBJECT: City Project 9838 Drainage Area 30 (Albany/Fulton) Storm Drainage Improvements SUMMARY RECOMMENDATION: It is recommended by staff that the City Council authorize the attached resolution for additional design services with Blank, Wesselink, Cook & Associates, Inc. (BWC) to design an alternate outfall for the southern portion of Drainage Area 30 which encompasses the area generally south of the intersection of Albany / Fulton. The proposal is for an additional $23,000 for the preparation of design and construction documents and$4,100 for construction services. BACKGROUND: In December 1998, the City entered into an agreement with BWC to prepare a design for a storm drainage project contained within the southern portion of Drainage Area 30. This area has an ongoing drainage problem primarily related to the flat terrain and lack of an immediately accessible outfall for area storm water. Initial designs have put forward various outfall alternatives which have been thoroughly explored to the point of easement negotiations with various area residents. In fall 1999, City staff authorized some additional work on the part of BWC to accommodate the most recent exploration of an outfall to the southwest along Orchard Street. To date, attempts to secure easements have been fairly fruitless. Many concerns are centered around the quantity of storm water that may be added to the defined drainage ways that direct water to the southwest. City staff, in consultation with BWC, has determined that the best option for a storm water outfall for this area is to incorporate the Drainage Area 30 storm sewer improvement into the design that is currently being prepared for an improvement to Fitzgerald Road from Fontaine Drive to Baltimore Avenue. The City's storm drainage master plan identifies the outfall for Drainage Area 30 to be the Fitzgerald Road/Baltimore Avenue area.
