Recommendation
It is recommended that Town Council direct the Town Manager to execute an IGA between the Town of Paradise Valley and the City of Phoenix for stormwater improvements at 52nd Street and Turquoise.
Background
SUMMARY STATEMENT:
The Town and the City of Phoenix (“Phoenix”) desire to enter into an Intergovernmental Agreement (Attached) related to stormwater issues along 52nd Street south of Turquoise Avenue, as well as near the intersection of 53rd Place and Mountain View (see attached Project Location Map).
Since 2013 the Town has been working with the City of Phoenix to study a localized flooding issue along the eastern side of 52nd Street south of Turquoise Avenue. The Town Limits are down the centerline of 52nd Street at this area, although the town maintains all of the right-of-way. Several homes within the City of Phoenix have experienced flooding in the past several years and Phoenix initiated and funded a small study to identify the existing conditions in the area and proposed solutions. The study identified several elements within the Town that, if installed, would assist in alleviating the flooding issues. These elements include a new sedimentation basin, roadway re-profiling, and some new curbing. The new sedimentation basin will significantly decrease the amount of sediment deposited on 52nd Street during a storm event, which will make it quicker and easier for the Public Works Department to clean afterwards.
Phoenix will oversee the design and construction of the project, with the exception of one element, in which the town will pay for separately, outside of the IGA. The outside element includes the removal of an existing elevated chicane island and replacing it with a flush island inlaid with pavers. The City of Phoenix approved the IGA at their October 4th City Council Meeting.
BUDGETARY IMPACT:
Approval of this IGA will cost the town $90,000. The town has budgeted $100,000 in the FY17-18 CIP in anticipation for this project. The remaining $10,000 will be utilized to remove the existing chicane and construct a new chicane on 52nd Street at this location consistent with the plans.
