RE:

Annexation – Kaw Valley Drainage District Concerns

 

Please include the following item on the City Commission agenda for consideration at the November 9, 2010 meeting:

ANNEXATION

This memorandum is in response to a letter from the Douglas County Kaw Drainage District expressing concerns within the Baldwin Creek Watershed. The letter specifically states a concern for "the impact of flooding downstream land".  The proposed annexation of approximately 51.13 acres located at the southwest corner of N. 1800 Road (Farmer's Turnpike) and E. 1000 Road (Queens Road extended) was the trigger for the District's letter. 

 

DEVELOPMENT WITHIN THE WATERSHED

An annexation of the property would require it to meet all of the stormwater management criteria just as if it were a contiguous part of the City.  The property would be required to meet the allowable release rate of 1.8 cubic feet per second per acre for parcels greater than one half acre.  In addition the property would also be subject to pay fees into the stormwater utility fund.  Currently Douglas County does not have any stormwater detention requirements.
