The Iowa DNR and Iowa Geologic Survey approached us in the Fall of 2007 to educate us on their geologic mapping program and to ask us for our support to map two USGS quadrangles (Davenport East and Davenport West). We provided a letter of support for that effort and they were subsequently able to secure approval (at no cost to Scott County). They recently completed that project and you can view the resulting maps in PDF format here:
Iowa DNR Geologic Maps for Scott County
We have not yet received the GIS format files, but expect they will be available shortly. This information will be valuable for planning and environmental analysis.
The Iowa DNR and IGS are now hoping to take the next step. They would like to continue mapping the rest of Scott County through the Iowa STATEMAP program! They have again asked us for a letter of support to demonstrate local interest and value. I believe the geologic data will be very useful, particularly to our Health and Planning departments.
Improved geologic data will be useful in a number of county applications. For example, our Health Department is interested in identifying the areas of the county susceptible to groundwater contamination and is investigating the use of sand point wells, nitrate levels and other important factors that contribute to this problem. Septic systems are also a concern.
The Scott County Planning and Development Department has recently updated the Scott County Comprehensive Plan. They can leverage geologic, land use, zoning and other related spatial data in GIS to improve decision making for land use and resource management.
There is potential to use the geologic data in Conservation, Secondary Roads and Solid Waste Management. We anticipate working in partnership with the IGS and Iowa DNR to find other uses for the information as our own local GIS layer development efforts continue and more data is added to the mix.
