2
3 AN ORDINANCE TO AMEND VARIOUS PROVISIONS OF CHAPTER 36
4 OF THE CODE OF ORDINANCES OF THE CITY OF LITTLE ROCK TO
5 ALLOW THE USE OF LOW IMPACT DEVELOPMENT (LID); AND,
6 FOR OTHER PURPOSES.
7
8 WHEREAS the Cityof Little Rock is committed to reducingthe volume of nonpoint source runoff,
p
9 including stormwater, flowing into its storm sewer system, improving the water quality of its surface
10 waters, and decreasing underground stormwater conveyance that may ultimately runoff into the Arkansas
11 River; and,
12 WHEREAS, Unlike traditional stormwater management, which collects and conveys stormwater
13 runoff through storm drains,pipes, or other conveyances to a centralized stormwater facility, Low Impact
14 Development (LID) takes a different approach. It utilizes design techniques to maintain as closely as
15 practical the site's pre-development runoff rates and volumes for the required rainfall event. The goal of
16 LID is to mimic a site's pre-development hydrology by using design techniques that infiltrate, filter, store,
17 evaporate, and detain runoff close to the source; and,
18 WHEREAS, the current City of Little Rock Zoning Ordinance does not currently allow the
19 utilization of LID techniques as an option for stormwater management requirements in land development
20 projects without first having to obtain a variance from the City of Little Rock Planning Commission or
21 Board of Adjustment; and,
22 WHEREAS, it is the intent of the City of Little Rock to amend its current zoning ordinance to allow
23 Low Impact Development(LID); and,
24 NOW, THEREFORE,BE IT ORDAINED BY THE BOARD OF DIRECTORS OF THE CITY
25 OF LITTLE ROCK,ARKANSAS:
