LANGUAGE RELATED TO LOW IMPACT DEVELOPMENT.
WHEREAS, the City of Edmonds has been issued a Western Washington Phase II
Municipal Stormwater Permit by the Department of Ecology `Permit'; and
WHEREAS, this Permit mandates cities reduce the discharge of stormwater pollutants to
the maximum extent feasible and implement a stormwater management program that integrates
Low Impact Development Practices into City policy and code; and
WHEREAS, the City has for many years worked towards reducing the concentration of
pollutants in City stormwater and has revised codes, policies and practices to better address these
issues; and

a process in 2015 of reviewing and revising codes, policies, and standard details; and
WHEREAS, The City's Stormwater Code (ECDC 18.30) went through a major overhaul
process to address Permit requirements and was approved by City Council on October 4, 2016,
with an effective date of January 1, 2017; and
WHEREAS, in addition to updating the City's Stormwater Code, all other development -
related codes and enforceable documents have been reviewed to eliminate potential barriers that
would prevent the incorporation of low impact development principles and best management
practices; and
WHEREAS, the proposed code changes were reviewed by the Planning Board on
September 26, 2017 and presented at a Public Hearing before the Board on October 11, 2017; and
WHEREAS, the Planning Board gave approval for the proposed changes to move forward

B. Landscaping— Parking Lots.
1. Parking areas shall be screened from pedestrian -oriented areas through the
use of trees, shrubs, walls and/or trellis structures with plants.
2. Parking lots shall provide landscaping next to buildings and along walkways.
Landscape beds within parking lots shall have a 90 percent ground coverage in

3. Parking areas shall have at least one tree per every 10 parking stalls.
B. Design Goals for Project. Incorporate goals for integration of sustainability at
earliest stages of design process possible. Decide on projected levels of
achievement for the project. For example: The project will achieve at least a
four -star level of the Built Green of Washington program.
1. Site Design and Water Use. The proposed development will integrate low -
impact development techniques where r-L- _ feasible. For the purposes of
this section, low -impact development techniques shall include, but shall re not
be -limited to, the following: the use of bioswales, green roofs, and of=_==Fete
open cell/vegetated pavers.
"Reasonably feasible" shall be determined based upon the physical
characteristics of the property and its suitability for the technique; cost alone
shall not render the use of low -impact techniques unreasonable or unfeasible.
Additional techniques for strong consideration:
a. Rainwater harvesting —for use in site irrigation and possibly toilet flushing for
commercial uses.
b. Utilization of water efficient fixtures throughout the project.
2. Energy Resources. Increase efficiency by maximizing equipment efficiency and
using control strategies. Design to reduce energy and electricity consumption
and eliminate unnecessary demand. Include use of alternative energy resources
wherever possible.
3. Material Resources.
a. Plan for long-term use by designing for adaptability, specifying durable
materials and considering energy and maintenance needs.
b. Select resource -efficient and recycled materials, where possible, that
minimize environmental impact.
c. Utilize wood from sustainable sources.
d. Encourage recycling of waste with easy access recycling stations and pickup
areas.
e. Manage construction demolition and waste with a jobsite recycling plan.
4. Health and Indoor Air Quality. Utilize multiple strategies to limit emissions
from materials. Select low VOC and nontoxic materials, paints and finishes. Pay
special attention to residential units in selection of finishes and paints for low or
no toxicity.
