ITEM TITLE: NATURAL RESOURCE INVENTORIES AND PROTECTIONS FOR UGB
EXPANSION AREAS – PROGRESS UPDATE
ACTION
REQUESTED:
Review wetland, riparian, and wildlife habitat inventory results, and confirm protection
approaches for significant natural resources to inform Springfield’s path forward.
ISSUE
STATEMENT:
Since 2020, Springfield has been working with partner agencies and stakeholders to
identify and assess wetlands, riparian corridors, and wildlife habitat in the areas where
the City recently expanded its urban growth boundary (UGB). With the identification
and assessment phase nearly complete, staff seek confirmation from the Planning
Commission on protection approaches for locally significant natural resources in
preparation for further stakeholder engagement and development of draft legislative
amendments for Planning Commission consideration.

DISCUSSION: Project Background: Since the State’s acknowledgement of Springfield’s UGB
expansion in 2019, Springfield has been working to define a framework for development
in the areas where the UGB expanded. One of several early steps to understanding where
future development may be best-sited is to identify, evaluate, and protect locally
significant natural resources in these areas. In 2020, this project set out to address wetlands
and riparian corridors, and in 2021 the scope broadened to include wildlife habitat
assessments and Water Quality Limited Watercourses.
Commission Involvement to Date: Early in the project, the Planning Commission, acting
in its capacity as the Committee for Citizen Involvement, approved the project’s
Community Engagement Plan. On July 17, 2020, staff updated the Planning Commission
on the status of the project in a Communication Packet Memo, and the CCI amended the
Community Engagement Plan in December that year. On November 8, 2021 and
December 6, 2022, staff shared information about the project’s community engagement
activities with the Planning Commission.
Project Status: At the work session, staff will review wetland, riparian, and wildlife
habitat inventory results and confirm protection approaches in advance of further
stakeholder engagement and drafting updates to Springfield’s Natural Resources Study for
Planning Commission review later this year.
Next Steps: The City Council is scheduled to hold a project work session at their May 22,
2023 meeting.

WETLANDS & RIPARIAN CORRIDORS
WHAT ARE THEY?
WHAT DO THEY DO? WHY DOES THIS MATTER?
Wetlands and riparian corridors have many functions. They:
Riparian corridors are waterways and
the land area directly along the
waterway. When left in a more natural
state, they are buffers between the
water and many human impacts.
Wetlands are areas that are saturated
by surface water or ground water, where
such water occurs at a frequency and
duration sufficient to support types of
vegetation that are adapted for life in
saturated soil conditions. Simply stated,
wetlands are areas with plants and soils
that are best-suited to wet conditions.
Equip us to handle flood emergencies: Wetlands and
riparian corridors can act like sponges and absorb floodwater.
An acre of wetland can store between 1-1.5 million gallons of
floodwater.
Enhance water quality: The vegetation in these areas reduces
erosion of areas along the bank (especially riparian areas)
because of roots in the soil. Both the underground and
aboveground parts of a plant keep waste and other residue like
sediment out of water when it flows to a stream or river after
the rain. Wetlands act as filters and purifiers because they
absorb and hold water before it soaks into the ground.
Wetlands can remove as much as 90 percent of solids in water.
Provide various species places to live: The strips of land that
follow the river are critical travel corridors because they allow
animals to move freely. Shade from trees and other plants
cools water to a temperature that allows aquatic-based life to
survive. The waterbodies themselves serve as habitat that
allows for shelter to hide, breed, or sleep. Although wetlands
only make up about 5 percent of the land surface in the
contiguous United States, wetlands are home to 31 percent of
our nation’s plant species.
Boost aesthetic & property values: Market prices can
sometimes reflect the “quality of life” or amenity values
provided by wetlands and riparian corridors. For residential
development in urban areas, the market price of properties
with views of natural areas is often greater than the price of
similar properties without these views.
Offer spaces for recreation & education: These areas allow
for great places to enjoy and learn about the outdoors.
Opportunities for recreation include parks and trails. Here,
classes and tours can also interact up-close with the featured
educational topic.

Subject: Natural Resource Inventories & Protections for
UGB Expansion Areas MEMORANDUM
ISSUE: Since 2020, Springfield has been working with partner agencies and stakeholders to

COUNCIL GOALS/
MANDATE:
Council Goals: Mandate
BACKGROUND:
Existing Natural Resources Regulatory Framework
Oregon Regulations
Statewide Planning Goal 5
(Natural Resources, Scenic and
Historic Areas, and Open
Spaces) directs local
governments to protect locally
significant wetlands, riparian
areas, and wildlife habitat while
Goal 6 (Air, Water and Land
Resources Quality) requires that
waste and process discharge
from future development shall
not threaten to violate, or violate
applicable state or federal
environmental quality statutes,
rules, and standards.
Goal 5 establishes alternative
methods for establishing
protections for significant
wetlands and riparian corridors1, a “Standard” method and a “Safe Harbor” method. The
“Standard” method necessitates what is called an Economic, Social, Environmental and Energy
1 Oregon Administrative Rules (OAR) 660-023-0110(6) stipulates that local governments shall develop
programs to protect wildlife habitat following the Standard method.

(ESEE) Analysis. This analysis formally lays out the justification for a decision to protect,
partially protect, or not protect a resource by looking at the consequences of not allowing,
partially allowing, or fully allowing uses that may be considered incompatible with natural areas
("conflicting uses").
Springfield Policies
Springfield first adopted the Springfield Natural Resource Study (NR Study) in 2002, based on a
Local Wetland Inventory that was adopted in 1998. Springfield then adopted its Natural
Resource Inventory in 2004 that identified riparian corridors within the UGB at that time,
incorporated a Wildlife Habitat Assessment, and accounted for Water Quality Limited
Watercourses2.
The original NR Study used the “Standard” protection method, meaning an ESEE analysis was
utilized to justify a more nuanced natural resource protection program that limits conflicting uses
through development review procedures and standards. In 2011, the NR Study was updated to
incorporate newly identified significant natural resources in the Glenwood area of Springfield.
That update also contemplated alternative protection approaches but ultimately integrated into
the City’s existing regulatory framework.
Protection Considerations for UGB Expansion Area Resources
As noted above, alternative methods exist for establishing protections for significant wetlands
and riparian corridors in the UGB Expansion Areas. The figure below identifies key aspects of
each approach.
Though the “Safe Harbor” method is intended to be procedurally more streamlined, it results in
highly prescriptive development requirements. The “Standard” approach is more qualitative,
relying on the local government to demonstrate that the proposed protection program is
‘adequate’ by objectively balancing contending economic, social, environmental, and energy
priorities. Additionally, given that Springfield has implementation (Development Code)
provisions already in place, efficiencies gained in deciding which land should have placed on its
use to protect significant natural resources would be offset by the effort needed to establish new
development provisions. As such, staff recommends continuing to balance development
priorities with natural resource protection by utilizing the “Standard” approach to protect
significant wetland, riparian, and wildlife habitat sites in the UGB Expansion Areas.
2 Springfield currently does not have an inventory of, or clear protection implementation, for wildlife habitat in
areas outside of wetlands and riparian corridors (upland wildlife habitat). Wildlife habitat is a key function of
most of Springfield inventoried wetlands and riparian areas.

MEMORANDUM 4/26/2023 Page 3
RECOMMENDED ACTION: Confirm that Springfield will follow the “Standard” approach
for protecting significant wetland, riparian, and wildlife habitat sites in the UGB Expansion
Areas in conformance with Springfield’s existing regulatory framework.
