Client: St. Louis County

M3 Engineering is part of the Cole &Associates team that is preparing the ADA Transition Plan for the entire St. Louis County. The purpose of the project is to identify intersections, sidewalks and bus stops that are ADA non-compliant.  M3 will create a scalable Geodatabase using the ESRI ArcGIS system that will allow the County to increase its existing database to accommodate future volumes of collected data.

Hand held field computers will be loaded with the ArcGIS database for use by field crews, thus creating a mobile GIS platform.  Information such as County right-of-way, aerial background, maintenance/council district and evaluation locations will be displayed.  The screen will include pre-defined pull down menus corresponding to data fields such as type of feature (sidewalk, ramp, etc.), slope, width and condition. 

The team will work with stakeholders to identify the necessary improvements to overcome ADA barriers, the cost of those improvements and a reasonable schedule for implementation.  This will include querying the GIS to generate lists, or quantities, of ADA barriers, along with the type of barrier and the required improvement.  Unit costs can be applied to these quantities to produce construction cost estimates.  The query can easily be adjusted, as desired, as the Transition Plan is refined.  After stakeholders have decided what aspects of the Transition Plan are most important, we will apply the preferences to the proposed improvements to generate a prioritized list of projects.
