SURVEYORS REPORT:
Gregg Cantwell stated this site is located within the Hurricane and (Canary) Watershed, Development did not encroach or discharge directly into Hurricane Ditch, and the site met the discharge and water quality requirements (pre2023) by both Whiteland and Johnson County. 
Mr. Cantwell stated the Pre Developed warehouse site was (and still technically in the Canary watershed, The Post Developed site discharges to the right of way of I -65, A pipe under I-65
drains the right of way of I-65 and storm water moves east along a small swale and across farm to the Hurricane Ditch.   This site is now holding more water, discharging at a greater volume.  
Mr. Cantwell stated if a greater volume of water is occurring in the watercourse erosion is inevitable.

Mr. Cantwell stated the Surveyor will study the drainage discharge of this site, and if appropriate change the watershed. 

Mr. Cantwell stated for the record I am neither an attorney, or engineer.   

In Mr. Cantwell’s opinion:

1	At least  a portion of the 84  acre Warehouse has changed from Canary to 
To Hurricane Legal Drain.
2	This could be a civil matter.
3	The change from Canary to  Hurricane, could have an impact of the drainage 
of I- 65  AND Hurricane Road.
4	Surveyor recommends action to protect Hurricane Ditch from erosion and 
sediment.
