The Consultant must be able to professionally and accurately perform two primary tasks. The first is the normal, annual updates to the tax maps which will incorporate all changes to individual lots. The second is the review and analyze any new information submitted by property owners between June 30, 2007 and March 1, 2008, and prepare, as necessary, individualized revised and/or corrected tax maps that correspond to any reliable information submitted by the property owners. A third task, which will be performed depending on available funding, calls for the Consultant to advise and guide the City on GIS issues, and to initiate, using the existing data base, the creation of basic GIS mapping that can be built upon over the next few years.
