Introduction
High
groundwater levels influence the area near a levee during flood
conditions. When the water level in the river is above the natural
ground elevation on the dry side of the levee, groundwater begins to move and
tends to come to the surface near the levee. This movement of water
is called “underseepage.” Underseepage can exert significant forces on buried
utilities, foundations, and slabs. If not adequately controlled,
underseepage can cause damage to properties or the levee.
Underseepage
forces are not a typical consideration in building and site
design. If not accounted for by the engineer or architect, these
forces can cause damage to facilities and promote catastrophic levee failure.
The North Kansas City Levee District (District) requires a design review of all
proposed construction projects within the “critical area” of the levee. The
reviews help ensure compliance with the U.S. Army Corps of Engineers for work
within the critical. These reviews help to ensure that the flood protection
system retains its integrity.
For any
property owner, developer, contractor, excavator, utility, or other
parties—including any federal, state, or local government or agency, or any
agent working thereunder—to develop or make improvements to lands located
within the critical area of the North Kansas City Levee District, an applicant
must comply with the following procedures to obtain acceptance to perform the
work.
Definition
of Critical Zone
On the
landside of the levee, the critical zone includes all areas within 500 feet of
the levee centerline or within the limits of the landside stability berm,
whichever is greater.
On the
riverside of the levee, the critical zone includes all areas within 300 feet of
the levee centerline.
Review
Fees
The District requires a funding agreement for technical reviews. The agreement, in the form of a plan review fee and a construction assurance deposit, is used to reimburse the District for costs associated with each technical review. Agreement balances will be refunded upon construction completion or project disapproval. Agreement amounts are developed based on the following:
- Plan Review Fee: Required to cover the cost of administration and engineering reviews. Developed based on the number of drawing sheets submitted for review, estimated review duration, construction monitoring or on-site personnel requirements, and preliminary communication.
- Construction Assurance Deposit: Required to provide assurance that projects are constructed per the approved plans and specifications and that areas within the District are subsequently and adequately restored. Developed based on the location of the project within the District area, the type of project being constructed, construction duration, and the size and complexity of the project.
Additional
Fees
An
additional fee of $1,500 per day is required for projects requiring field
observation by District personnel. Field observation is typically required for
emergency repairs and rework of unpermitted projects.
