size it is likely that some additional street right -of -way or easement would be needed. As in previous years the Watersheds current enacted stormwater treatment regulations require infiltration of the first inch of storm water runoff from impervious surfaces. Previous street projects the City completed utilized rainwater gardens to achieve this infiltration standard therefore, in a continued effort to effectively treat storm water, rainwater gardens will once again be considered for treatment of storm water runoff along this roadway. B. SCHLETTY DRIVE Schletty Drive is proposed to be reconstructed as a 28 -foot wide urban section with concrete curb and gutter. Municipal watermain would be extended from the existing 8 -inch stub near Little Canada Road to provide water service to those currently not served along with fire protection for the neighborhood. At this time we anticipate the removal and replacement of all the concrete curb and gutter because of the impacts necessary to install the watermain, hydrants, and services. Because Schletty Drive is an existing urban section there is an existing storm sewer system serving the street. Those at the informational meeting felt the system was functioning adequately, however we will review the system to determine if improvements are needed.

Previous street projects the City completed utilized rainwater gardens to achieve this infiltration standard therefore, in a continued effort to effectively treat storm water, rainwater gardens will once again be considered for treatment of storm water runoff along this roadway. There are several City owned properties along this street and could be used for infiltration if sufficient support is not received from the neighborhood. VIII. RIGHT -OF -WAY & EASEMENTS The City may need to acquire waivers of trespass and /or drainage and utility easements for grading work, constructing the rainwater gardens, and watermain installation if there is not sufficient room within the rights -of -way to do so. A waiver of trespass allows entry by City personnel and its agents, the Contractor, and subcontractors onto private property for the purpose of inspection and other construction related work only during the duration of the project. In the past the City has requested approval from residents to construct a rain garden in front of their property or on their property. The City has only required verbal approval and no documentation of the acceptance of a rain garden has ever been obtained. We would ask that Council provide direction on if a verbal approval is sufficient or if a signed form authorizing the garden be required from residents. 10
