RE: Consulting Services for Geodetic Control Network Update and Aerial
Photography Project
DATE: January 21, 2020
BACKGROUND
In Fiscal Year 2019 (FY19), the City Council approved a capital improvement package for aerial
orthophotography and LiDAR data collection in the amount of $160,000. The purpose of this
improvement package was to procure aerial orthophotography for the City of Dubuque and
surrounding area, update the City's GIS control network, and to generate LiDAR data and 1'
contours.
The last time the City received horizontally and vertically accurate aerial photography was in 2009.
The City's control network has not been updated since 1996. The current network is out of date
related to its coordinate system and some location monuments are in need repair or
replacement. The network may also require expansion to fulfill the needs of the City's 2-mile
project review area and future community expansion.
DISCUSSION
A request for proposals was released in September 2019. Two firms submitted proposals for the
project: Lidar America, Inc, at a cost of $96,908, and Dan Corbin, Inc, at a cost of$42,398. Of
the two firms who submitted proposals for this project, Dan Corbin, Inc, is the consultant who will
best meet the needs of the City of Dubuque. Dan Corbin, Inc, has a significant amount of
experience performing this type of work in cities and counties across the state of lowa. Hiring
Dan Corbin, Inc, will allow an expert in the field to manage the project for the City, and allow the
GIS Coordinator/Analyst to work on other key functions of her position.
ACTION REQUESTED
The GIS Coordinator/Analyst respectfully requests the City Council's approval to allow City
Manager Mike Van Milligen to negotiate and execute a contract with Dan Corbin, Inc for this
project.
