REQUIRED STORMWATER SCOPING SHEET USE POLICY:
In October 2003, Springfield Public Works released a trial "stormwater scoping sheet," provided to help
engineers and developers meet stormwater requirements in the Springfield Development Code (SDC) and
Engineering Design Standards and Procedures Manual (EDSPM). After a five month trial period, it became
apparent that users of the scoping sheet submitted much more complete applications than non-users. An added
bonus was a decrease in the overall review time spent on the applications, resulting in quicker notice of
decisions.
As a result of the benefits of the scoping sheets, the City has decided to make their use a mandatory process.
Current city policy is that the use of stormwater scoping sheets is required for all applications which require
development review. All applications submitted to the City shall provide a copy of a completed stormwater
seeping sheet with the application packet. Attached with this letter is the latest version of the scoping sheet,
which reflects changes requested by the development community.
PLEASE NOTE: SUBMITTED APPLICATIONS WILL NOW BE REQUIRED TO SUBMIT A
COMPLETED STORMWATER SCOPING SHEET, STORMWATER STUDY AND PLANS IN
CONFORMANCE WITH THE SCOPE REQUIREMENTS
DIRECTIONS FOR USING STORMWATER SCOPING SHEETS ARE AS FOLLOWS:
1.) Obtain scoping sheet from application packet, city website, or other location.
2.) Fill out project information (top half of front sheet) prior to commencement of work on stormwater study.
(Note: Do not sign scoping sheet until it is received from the City with requirements checked.)
3.) Mail, fax, or email all pages to: City of Springfield, Development and Public Works Dept., Atm: Clayton
McEachem.
4.) Receive completed scoping sheet (filled out by the City) indicating minimum requirements for a complete
stormwater study.
5.) Include four (4) copies of complete scoping sheet (signed by engineer at the bottom of page 2), stormwater
study and plans that comply with the minimum required scope with submittal of application packet. The
scoping sheet shall be included as an attachment, inside the front cover of the stormwater study.
Siormwater scoping sheets can be found with all application packets (City website and the DPW front counter)
as well as on the Engineering and Construction Resources webpage located at: http://www.springfield-

This memo (Attachment 1) includes information supporting the Site Plan Review Application
for Thurston Hills Natural Area Park (THNA), dated September 1", 2020. It includes a
description of proposed improvements, a proposed project timeline, and all of the submittal
requirements for Site Plan Review.
DESCRIPTION OF PROPOSAL
In 2017, Willamalane Park and Recreation District (District) developed the North
Trailhead and associated trails (Lower & Upper Mossy Maple, Acer Spades and Yew
Haw) to provide the public with access to the recently acquired Thurston Hills Natural
Area. The trailhead located at 7575 McKenzie Highway is intended to support motorized
(i.e, vehicles) access to the site with vehicle parking for up to 49 cars. Development of
the site and public access were identified as priorities in the Willamalane Park and
Recreation District Comprehensive Plan (2012) as well as the Rivers to Ridges Vision
Plan (2003). The North Trailhead will also provide future motorized access for the public
to Bureau of Land Management (BLM) Property adjacent to Thurston Hills Natural Area
that will be developed with a complimentary and connected multi -use trail system. With
initial site development and access complete, there are now additional opportunities to
continue recreational development.
The District is proposing to start development of Phase Two in the spring of 2020, which
includes approximately 6.3 miles of new trails that will provide close -to -home access to
the site (EXHIBIT A). Additionally, this next phase of development will provide non -
motorized connections to the site from the greater Springfield- Eugene area by connecting
the trails to the former Weyerhaeuser Haul Road, which provides connectivity to the
Millrace Path and Middle Fork Path.
Trails will be constructed using International Mountain Biking Association (IMBA) trail
guidelines and standards in addition to best -practices identified through the American
Trails Organization. Design and construction of these trails will be conducted by a private
contractor in addition to volunteer crews managed by District staff (See EXIBIT A) for
location of Phase Two trail development). The District will ensure high quality trails
through its procurement process, by requiring the contractor to have constructed similar
trails in the past, be a member of the Professional Trail Builders Association and have a
list of references and past examples of similar work for the District to review. See
EXHIBIT B for details on trail construction specifications. Final details regarding trail
alignments will be submitted to the City prior to construction as part of obtaining a Land
Development and Alteration Permit and a Tree Felling Permit for trail construction.
The District has not identified any potential trailhead possibilities on the site plan map
(EXHBIT A). The District is proposing that this next phase and the increased access that
it will provide for the public is focused on non -motorized access to the site. Development
of a trailhead is considerably more difficult on the west side of the property. The District
will continue to investigate options for development of a trailhead that could serve patrons
wanting to park their vehicles to access the west side of the property and will do a site
plan modification when that location is identified. To that end we are focused to
providing non -motorized access to the site via the former Weyerhaeuser Haul Road,
recently renamed the Thurston Hills Path, as part of the phase two development. There
will be no signage that designates any place other than the trailhead at 7575 McKenzie
Highway as a trailhead. Any signage on the site or leading the public to the improved
access points from the west will be identified as non -motorized access points. Any
information regarding the location of access points on the west side of the site will remain
as non -motorized access points.
The main purpose in developing trails on the west side of the property as part of this
Phase Two trail development is to provide improved close -to -home recreational
opportunities in the public. The current designated trail on the west side of the property is
a steep gravel access road that does not provide a high quality user experience. Phase Two
trail development will provide a better uphill and downhill trail experience at a more
moderate grade (average 8%) than the existing Camas Crest Trail (i.e., main access road
on the west side of the property).
EXHIBIT B provides examples of the trail specifications that will be included in the
request for quotes for the development of the next phase of trails in Phase Two. The trails
will be constructed in such a way as to minimize erosion on the trail as well as one the
site. Features such as grade reversals and out -sloping will be used throughout the trails to
get water off of the trail tread thereby limiting possible erosion. Trails will be constructed
during the dry season to minimize any likelihood of erosion or impacts off site.
Contractors constructing the trail will use erosion control devices, such as waddles, if rain
is forecast during the construction period. Areas disturbed by construction and adjacent to
the constructed trails will be seeded with native (orbs and grasses to stabilize the soil,
improve the user experience as well as limit any possible erosion. The District will
provide the City with a detailed plan as part of its Land Development and Alteration
Permit (LDAP) for trail construction. Additionally, in the event of tree removal being
necessary for trail development and construction, the District will obtain a Tree Felling
Permit from the City of Springfield.
Physical Features: The site is a diverse 665 -acre natural area park with a variety of
different habitats. From the trailhead at 7575 McKenzie highway the vegetation is mixed
conifer/hardwood forest running along the north facing slope of the ridge. The majority of
the north facing slopes contain similar vegetation. The south facing slopes of the property
are comprised of oak woodlands, savannas and prairie EXHIBIT C (Vegetation Map).
There are some areas of mixed conifer and hardwood forest, but primarily on the north
facing slopes. Much of the oak habitat in this portion of the natural area has been
encroached with conifers due to fire suppression and will require restoration work in the
future. Much of the understory throughout the site is comprised of a mix of invasive and
native vegetation.
The site's topography can be described as having rolling to steep topography. The
elevation ranges from about 600 feet at the southern edge of the property (low point) and
about 940 feet at the northern edge, to 1,625 feet at the eastern edge about halfway
between the north and south boundaries (EXHIBIT D). The topography of the site is
divided between two watersheds; the McKenzie River to the north and the Middle Fork of
the Willamette River to the south and west. On the far western side of the natural area the
slopes vary from 0-20%, to 30-40%. As elevation increases towards the east, the slopes
begin to get steeper, varying from 40-60% to as high as 60-80% and 90-120% at the
highpoints. The trail design siting criteria being used for this project call for trails to be
sited away from steep slopes to avoid potential erosion issues or to create full -bench trails
with erosion control features, such as grade reversals, throughout. The north side of the
natural area is primarily composed of a mix of landslide deposits. A major topographical
feature of the site is a rock cl iff ridgelme located in the north central portion of the site.
Hydrology: The site does not contain any permanent water bodies. The hydrology of the
site mainly consists of seasonal streams and drainage ways. The seasonal streams appear
mid -slope, below steeper sloped areas. There is one small mapped wetland on the site in
the south-central portion of the site that is listed as PFOA wetland (Palustrine, Forested,
A—temporary flooded- and/or saturated). There are no plans to construct trails within the
mapped wetland on the property (EXHBIT E).
