 Next Steps/Current Status
Background
 Johnson County, KS

20 incorporated cities

Population 451,086
(2000 census)

Total land area =
480 sq miles
 Johnson County
Stormwater
Management Program
Background
 1998 – 2002

7 Watershed Studies

Goals:
– Identify flooding
problems
– Develop solutions
– Generate new 100-yr
floodplain maps for
existing and fully
developed conditions
– Update FEMA regulatory
100-yr floodplain maps
 2007 - City of Olathe

Investigating general
flooding complaints

Notifying property
owners of floodplain
updates
City of Olathe

GOAL: Coordinate
stormwater
management with
Johnson County to
maximize funding

Stormwater
Management
Advisory Council
(SMAC)
 For projects that
qualify, SMAC
funds 75% of the
cost
The SMAC Process
 SMAC’s Primary Goal: Funding projects that
eliminate structure and street flooding
 Funded through a 0.1% sales tax in Johnson County
 To be eligible for SMAC funding several steps must
be taken:

Quantify the extent of flooding in an initial SMAC packet

Complete a Preliminary Engineering Study

Evaluation by SMAC of Preliminary Engineering Study

Placement on SMAC funding list, based on estimated cost
of the project vs. flood reduction benefit
