An Ordinance Enacting Floodplain Damage Prevention Regulations

ORDINANCE NO. 2013-04

AN ORDINANCE ENACTING FLOODPLAIN DAMAGE PREVENTION REGULATIONS.

WHEREAS, the State of Colorado Department of Natural Resources, Water Conservation Board (“CWCB”), has adopted standards for floodplain management, which are outlined in the Rules and Regulations for Regulatory Floodplains in Colorado (the Rules), effective January 14, 2014; and

WHEREAS, in order for the Town to participate in the National Flood Insurance Plan (“NFIP”) and be eligible to receive grant funding from CWCB, it must adopt the Rules, to become effective on or before January 14, 2014; and

WHEREAS, the Federal Emergency Management Agency (“FEMA”) has advised if the Rules are not adopted: federally backed loans and other financial assistance for acquisition or improvement of buildings in the mapped NFIP area will be unavailable; if a Presidential Disaster Declaration for flood is made, aid to survivors will be severely limited because the Town will not have demonstrated management of its flood risks by participating in NFIP; and Hazard Mitigation funding through FEMA would be unavailable; and

WHEREAS, the Town Board of Trustees has reviewed the Rules and by this Ordinance adopts them and incorporates them into the Keenesburg Municipal Code as the minimum standards for the Town.

NOW, THEREFORE, BE IT ORDAINED BY THE BOARD OF TRUSTEES OF THE TOWN OF KEENESBURG, COLORADO:

Section 1.Chapter 18 of the Keenesburg Municipal Code is hereby amended by the addition of a new Article III to read as follows:

(6) Help maintainastabletaxbasebyproviding for the sound use and developmentof flood- prone areasinsuch amanner astominimizefutureflood blightareas; and

(7) Insure thatpotentialbuyersarenotified thatpropertyislocatedin aflood hazard area.

Sec. 18-3-40Methods of reducing flood losses.

In order to accomplish itspurposes, thisordinanceusesthefollowingmethods:

(1) Restrictor prohibitusesthat aredangerousto health,safetyor propertyin timesof flood, or causeexcessive increasesin flood heightsor velocities;

(2) Require thatusesvulnerable to floods, including facilities whichservesuch uses, be protectedagainstflood damage atthetimeofinitialconstruction;

(3) Controlthealteration of naturalfloodplains, streamchannels, andnaturalprotectivebarriers, which are involved in theaccommodation of flood waters;

(4) Controlfilling, grading, dredgingand other developmentwhichmayincreaseflood damage;

(5) Preventor regulate the construction of flood barriers which willunnaturallydivertflood watersor which mayincreaseflood hazardsto otherlands.
