Development principles and practices as an elected official and in her professional capacity,and
WHEREAS, the development community is beginning to acknowledge and embrace the
advantages of utilizing Low Impact Development systems and solutions to better manage stormwater
runoff, and
WHEREAS, the City of Fayetteville recognizes the environmental benefit of Low Impact
Development practices for the greater good of the region's water resources.
NOW,THEREFORE,BE IT ORDAINED BY THE CITY COUNCIL OF THE CITY OF

CITY COUNCIL AGENDA MEMO
To: Mayor Jordan, City Council
Thru: Don Marr, Chief of Staff
Jeremy Pate, Development Services Director
From: Leif Olson, Associate PlannerAl
Date: 25 March 2010
Subject: ADM 10-3541 UDC Ch. 179: Low Impact Development
PROPOSAL:
Periodically, development projects are proposed that include the use of Low Impact Development systems and
structures in the overall stormwater management plan for the site. Unfortunately, a formal process for reviewing
and permitting such structures does not currently exist. As such, the applicant, elected officials, the Planning
Commission, Staff and the public have not had a clear process for reviewing and permitting these types of
stormwater structures. Planning Staff has therefore worked with Council member Sarah Lewis, a sponsor of this
ordinance, to draft an ordinance that would formalize a procedure for permitting, installing and maintaining
Low Impact Development systems and structures. Council member Lewis has been the main proponent for
developing a Low Impact Development chapter and this goal was further supported by the Mayor at the
Fayetteville Forward Summit. Council member Lewis also provided staff with relevant background information
and peer city examples through her work at the University of Arkansas. Planning Staff has worked closely with
the Engineering Department to draft standards and regulations that will be functional and effective. The

179.01 Purpose
It is the purpose of this chapter to provide a
regulatory basis for site design and development
which incorporates Low Impact Development
(LID) strategies into land development. This
chapter provides techniques for property owners,
builders and land developers to integrate site
appropriate stormwater management practices
while striving to maintain or enhance natural site
features. This may reduce or eliminate structural
components of a conventional storm water
management system.
Some of the existing natural site features typically
protected through the use of LID techniques are:
wetlands, floodplains, forested areas, hillsides,
riparian corridors and existing soils.
There are a variety of LID design alternatives that
allow professionals in the land development field
the flexibility to implement LID stormwater design
elements. The various LID practices can be used
alone or in series to maximize benefits to the site.
In most cases, some type of structural drainage
systems will also be required to be implemented
in conjunction with LID element. Akio,

of these systems must also be concurrent
with other code requirements such as
landscaping, fire access, etc. Systems that
are approved shall be integrated where their
design function dictates.
179.03 LID Site Design Strategies
(A) Definition. For the purposes of this chapter
Low Impact Development (LID) is a
stormwater management strategy concerned
with maintaining, restoring or replicating the
natural hydrologic functions of a site, where
possible, by employing a variety and
combination of natural and built features that
reduce the volume and velocity of
stormwater runoff, filter out its pollutants, and
facilitate the infiltration of water into the
ground.
(B) Site design strategies. Generally, site design
(8) To protect the safety and welfare of strategies will address the arrangement of
citizens, property owners, and buildings, roads, parking areas, and other
businesses by minimizing the negative features, and the conveyance of stormwater
impacts of stormwater discharge from runoff across the site. LID site design
land development. strategies are intended to complement the
CD179:3
TITLE XV UNIFIED DEVELOPMENT CODE
natural and built environment while
minimizing the generation of runoff. Site
design strategies should address some or all
of the following considerations:
(1) Necessary grading and land disturbance
should be designed to encourage sheet
flow and lengthen stormwater flow
paths.
(2) Natural drainage divides should be
maintained to keep flow paths
dispersed.
(3) Areas of impervious surfaces should be
separated and stormwater should be
conveyed across vegetated areas. This
assists runoff filtration and encourages
infiltration.
(4) Distribute small-scale LID strategies
across the development site in order to
maximize benefits.
(5) To the maximum extent possible, treat
Pollutant loads where the ,, are
generated.t
(6) Preserve naturally vegetated area ¢' it w`
soil types that slow runoff, '
pollutants and facilitate infiltration,

(c) Filter Strips: Filter strips are bands
of vegetation, usually grass, planted
between a stormwater pollutant
source and a downstream receiving
waterbody. Filter strips are very
effective adjacent to parking lots
where sheet flow is designed to
travel over the filter strip to a swale
or retention area. Filter strips trap
sediment and pollutants thereby
providing some infiltration while
slowing and dispersing stormwater
over a larger area.

The modern swale as a LID
element is utilized as both a method
of conveyance and retention, and
as an infiltration strategy. Dry
swales typically have 2 to 3 feet of

gravel base allowing stormwater to
infiltrate.

Overflow
An overflow outlet must

A drain spigot with garden
hose threading is needed
for irrigation.
