In the past, developers were required to control erosion during construction for projects disturbing 5 acres or more of land only. That has all changed; the 5 acre threshold has been reduced to 1 acre. There are now requirements for both erosion control and proper hazardous material storage during construction. Site planning must include measures to avoid sensitive areas, decrease impervious surface area, and provide for on-site treatment of stormwater runoff using Best Management Practices (BMPs). Construction projects must apply for a local permit which will include a review of plan sheets and project sequencing.

There are also requirements for "self-monitoring" and periodic reporting to local officials during construction. Local authorities will spot check construction sites to ensure proper measures are all in place. Following construction, the property owners are required to monitor, maintain, and report on the condition of on-site BMPs to ensure they continue to work properly. Links to GIS mapping, inspection forms, and permit forms can be found on the Tippecanoe County Drainage Board web page. Local, State, and Federal regulations requiring these changes can be found using the “Regulations” link below. These resources should help you plan and build a water quality friendly development without creating delays.
