RECOMMENDATION
It is recommended the City Council approve a contract for the orthophoto project from The
Sanborn Map Company, and authorize the City Manager to sign the contract and necessary
documents in an amount not to exceed $ 150,000 for orthophoto fly over, planimetric data,
and services per the attached quotation.
BACKGROUND
The City of Azusa participated in a formal RFP process with ten other cities. This was a
coordinated effort spearheaded by Thomas Mayer, City Engineer for the City of West Covina.
Eight responses to the RFP were received. Each city rated the proposals on the following:
general control, aerial both black & white and color, triangulation, ortho, methods, team,
experience, schedule, fee’s, fee structure, and alternatives. Once the initial rating was
completed the top 3 vendors were invited to do presentations to the cities. Once these were
completed, the cities selected the top firm. The following cities have executed the contract
for orthophoto acquisition, West Covina, Duarte, City of Industry, and Monrovia.
The GIS team which consisted of representatives from Community Development,
Redevelopment, Light & Water, and Information Services met with the selected vendor
several times to refine specific needs for Azusa. This includes the additional water service
area that extends south of the City, and a portion that is east. The attached map outlines
the project boundaries.
Product Accuracy
All the mapping data and products that will be generated for the City of Azusa under this
project will meet the National Map Accuracy Standards for the defined scale of data.
