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 seeping sheets is required for all applications which require development review. All applications submitted to the City shall provide a copy of a completed stormwater scoping 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 from 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., Attn: 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. Stormwater 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: httod/www.srdnefield- or_gov/DPW/EngineeringandConstructionResources htm under the Public Improvement Permit Projects Forms section.

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 EXIBFP 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 to 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 treed 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 forbs and gasses 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 conifedhardwood 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 cliff ridgeline 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, Artemporary flooded- and/or saturated). There are no plans to construct trails within the mapped wetland on the property (FXfIRIT E).
