How Overland Park Handles Environmental Rules: A Practical Guide

Overland Park maintains 130 local ordinances across all categories, and 5 of those deal specifically with environmental rules. Here is a breakdown of what the city actually requires, what is prohibited, and where Overland Park falls on the strict-to-permissive spectrum compared to other cities.

Coastal Development

Kansas is landlocked, so no coastal program exists anywhere in the state. Development near water in Overland Park runs through FEMA floodplain permits under OPMC 18.360, stream corridor setbacks under 18.365, and Corps Section 404 approval where wetlands are disturbed.

Key details: Coastal program: None; Kansas is landlocked. Freeboard: 2 feet above base flood elevation. Floodplain Administrator: Planning and Development Services Director. FIRM adopted: August 3, 2009. Floodway rule: No increase in base flood elevation.

Floodplain violations are misdemeanors under OPMC 18.100.110: fines up to $500, imprisonment up to six months, each day a separate offense, plus injunction and abatement suits.

Compared to other cities, Overland Park takes a harder line on coastal development. The enforcement and penalty structure reflects that.

Erosion Control

A land disturbance permit from Planning and Development Services precedes clearing, grading, filling or excavating. The exemption is narrow: under one acre, fill under three feet and 50 cubic yards, no slope steeper than 3:1, and no drainageway obstructed.

Key details: Permit: Land disturbance permit required. Exemption ceiling: Under 1 acre, 3 feet, 50 yards. Drainage standard: KC-APWA Section 5600, adopted by reference. Lot grading slope: 2.5 percent toward storm sewer. Building freeboard: 1 foot above 1% storm gradeline.

Working without a required permit draws a stop work order. The city may correct grading and drainage defects and assess costs against the permit, or as a lien on the parcel.

Flood Zones

Overland Park requires a floodplain development permit for any construction, substantial improvement or manufactured-home placement in the Special Flood Hazard Area before work begins. The Director of Planning and Development Services, acting as Floodplain Administrator, reviews every application under Chapter 18.360.

Key details: Permit required for: construction, improvement, manufactured homes in flood areas. Administering official: Director of Planning and Development Services. Notice before watercourse work: Kansas Dept. of Agriculture, Division of Water Resources. Amendment notice period: 20 days before public hearing. Max misdemeanor fine: $500 per offense.

Section 18.360.480 sets penalties and civil remedies for Chapter 18.360 violations by cross-reference to Section 18.100.110: an offense is a misdemeanor under K.S.A. 12-761 punishable by a fine up to $500 or up to six months imprisonment per offense, with each day of continuing violation a separate offense, and the City Attorney may also seek an injunction or other civil action to stop or correct unpermitted floodplain work.

This is one of the stricter rules in Overland Park's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.

Flood Elevation Requirements

New construction or substantial improvement in Overland Park's mapped Special Flood Hazard Areas must set the lowest floor at least two feet above Base Flood Elevation, a freeboard cushion above FEMA's minimum, certified by a licensed surveyor or professional engineer under Municipal Code 18.360.450.B.

Key details: Freeboard requirement: 2 feet above Base Flood Elevation. Applies in: A, AE, AH Special Flood Hazard zones. Certification required: Licensed surveyor or PE. Non-residential alternative: Floodproof to 2 ft above BFE. Governing section: Municipal Code 18.360.450.B.

Building below the required two-foot freeboard, or without the surveyor/engineer elevation certificate, is a violation the Floodplain Administrator enforces; the city can withhold or revoke building permits, require corrective elevation work, and deny flood insurance eligibility documentation until the certified elevation is on file. Substantially improved or damaged structures that don't meet 18.360.450 standards can also lose their nonconforming status and be barred from rebuilding to the same footprint if damage exceeds 50 percent of pre-damage market value.

Stormwater Management

Overland Park holds its own NPDES MS4 permit from KDHE and runs two ordinances: 16.210 requires treatment of runoff from new development and redevelopment, and 15.10.400 requires detention where downstream homes or streets flood.

Key details: MS4 permit: M-MO28-SU01, NPDES KSR410026. Permit term: January 2024 to December 2026. Treatment threshold: One acre of land disturbance. Redevelopment trigger: 5,000 square feet new impervious. Design manual: MARC and APWA BMP manual.

The city issues stop work orders, refuses inspections and abates at the owner's expense. Unpaid costs are certified to the County Clerk as a special assessment against the parcel.

This is not one of those rules that cities tend to ignore. Overland Park actively enforces its stormwater management requirements.

The Bottom Line

Overland Park is tougher than many cities when it comes to environmental rules. Out of the 5 rules covered here, 3 are rated strict. If you are a homeowner, renter, or business owner in Overland Park, take the time to understand these requirements before they become a problem. Most violations come with fines, and some repeat violations can escalate.

These rules come from Overland Park's publicly available municipal code. For complete penalty schedules, exemption details, and answers to common questions, see the individual ordinance pages throughout this guide.
