Substantial Improvement Requirements

Substantial improvement shall mean any repair from damage or destruction, reconstruction, improvement, or additions of a structure, the cost of which equals or exceeds 50% of the assessed tax value of the structure as is listed by the Alachua County Tax Assessors Office or by a certified appraisal. The assessed value of the structure shall be determined before the improvement is started, or if the structure has been damaged and is being restored, before the damage or destruction occurred.

Drainage System Maintenance

A community can lose a portion of its drainage system carrying or storage capacity due to dumping, debris, soil erosion and sedimentation, and overgrowth of vegetation. When this happens, flooding occurs more frequently and reaches higher elevations, subjecting properties otherwise protected to unnecessary risk of damage. Keep grass clippings and other debris out of stormwater drainage systems to prevent clogging and loss of stormwater storage and treatment capacity. Dumping trash and debris in drainage ways is against County ordinance. For more information visit the Alachua County Department of Environmental Protection water quality ordinance page.
