Development Process
All development in Moline requires review and approval by the appropriate City staff. Prior to construction, a property owner or contractor must first apply for a building permit and submit a site plan for review. The Land Development Division will review the site plan to ensure that new structures and development comply with adopted land use codes and policies. Proposals will be reviewed, at minimum, to verify that construction will meet applicable setbacks, height, and size (bulk) standards. For larger projects other than single or two-family residential construction, additional site plans for landscaping and lighting may also be required.

Site plans may be reviewed and approved administratively unless an applicant seeks a variance or special approval.  There is no fee for administrative site plan review.  Cursory reviews are also available upon request.

For information and examples on preparing a site plan, and a drawing template sheet, view the handout Preparing and Submitting a Site Plan.
