Title
Resolution to Approve a Professional Services Agreement with Quantum Spatial, Inc. for the 2018 Ortho Imagery and Impervious Surface GIS Data Update (RFP #17-28, $37,951.85)
Memorandum
Attached for your review and approval, please find a resolution approving a Professional Services Agreement with Quantum Spatial, Inc. for aerial imagery acquisition and geographic information system (GIS) data update in the amount of $37,951.85. The resolution also provides a ten percent contract contingency in the amount of $3,795.19.

The City of Ann Arbor's storm water utility fees are based on the impervious area contained on parcels. The calculation of the City's impervious area is determined by collecting aerial infrared photography and using the data to develop digital imagery that is incorporated into the City's GIS. Aerial imagery was last collected and updated in 2015. In order to accurately capture impervious area and periodically adjust storm water utility fees based on impervious area changes, the aerial ortho-imagery must be updated on a routine basis.

The aerial photography will be captured in the spring of 2018, with the development of the digital imagery proceeding only when the photographs are deemed acceptable. Quantum Spatial, Inc. will then continue with the impervious surface data update phase of the project.

The City issued a Request for Proposals (RFP #17-28) for collection of aerial photography, development of the data into ortho-imagery, and update of impervious surface data in a format compatible with the City's GIS. Of the two bids received, Quantum Spatial received the highest technical scores and was the lower bidder. The selection committee chose Quantum Spatial, Inc. to complete the project, based on their thorough work plan, wide range of relevant experience, and proven technical expertise.

Budget Impact:
Funding for this project is available in the FY18 approved Public Services Stormwater System Fund (Fund 0069) operating budget.
