To: Mayor Fasbender & City Council Members
From: Ryan Stempski – City Engineer
Date: April 9, 2019
Item: Authorize Project Work – 2020 Neighborhood Infrastructure Improvements
Council Action Requested:
The Council is requested to authorize the Engineering Department to take up the required field data
collection (surveying, pipe condition evaluation, and geotechnical investigation), design work, the
preparation of a feasibility report, and an appraised benefits analysis for the 2020 Neighborhood
Improvement Area.
Background Information:
The City’s Capital Street Improvement Plan calls for 15th Street from Tyler Street to Pine Street; 21st
Street E and Commerce Drive; Cannon Street, 22nd Street W, 23rd Street W, 24th Street W and 25th Street
W to be improved in 2020 as the City budget will allow. 15th Street and a portion of Cannon Street are
on the State Aid System and subject to certain design standards to receive State Aid funding. The
remainder of the streets are local and would receive a street improvement based on results of
geotechnical evaluation and the need determined for the underground utility improvements. Funding
through the Vermillion River Watershed has been secured in the amount of $184,600 to assist in water
quality improvements along 21st Street E.
A survey will need to be completed to begin design for these street segments. Water and sanitary sewer
mains will need to be evaluated for their current pipe condition. A geotechnical investigation will have
to be conducted to identify subsurface conditions in order to verify design assumptions and anticipate
construction costs. An appraised benefits analysis will also need to be completed to prepare a
preliminary assessment roll for the project. In order to initiate these improvements, the Council must
direct the preparation of a feasibility report as required by the statutory process for public
improvements that are specially assessed.
Financial Impact:
The costs for surveying, pipe condition assessment, appraised benefits analysis, and geotechnical
investigation will be covered through reimbursement from bonded debt funds when bonds are issued
for construction of the project in 2020. These services will need to be outsourced to consultants,
therefore fee estimates will be obtained and managed within the overall project budget.
