This 124-acre wooded parcel extends from the top of the hillside (level with Bluff Road) on the west, the city limits on the south and down to the Sandy River in the valley. An old logging road descends through the park, providing river access. Except for this feature, the park is formally undeveloped. Trailhead parking is limited to streetside parking along Marcy Street (a short, dead-end residential street east of Bluff Road). The site is located outside the City limits and urban growth boundary (UGB). For those in the know, this “under-discovered” park provides an easily accessible wilderness experience. Thus, the City Council and Park Board would like to preserve the area as a natural, passive-use park, but would like to begin to develop amenities appropriate for the site with this master plan to help guide efforts and provide a tool for seeking grant funding. The size, complex history and rich natural resources that make Sandy River Park such a special place, Vicinity Map and Site also necessitated a detailed approach to gaining Aerial Photo courtesy of an understanding of the background, current Google Maps conditions and potential of the site and progressed into a thorough, iterative design process. Regular meetings with the Technical Advisory Committee (TAC) and two major public outreach workshops were key to the success of this project. City staff, Council and Parks Board members, as well as Sandy citizens all played a significant role in the evolution of the resulting Sandy River Park Master Plan. This document supports the original goals of increasing residents’ awareness of the park and providing amenities that promote appropriate utilization of the park — improved trails, signage, trailhead parking, scenic viewpoints, seating and picnic facilities, improved shoreline conditions with potential for a pullout for kayakers/canoers using the future Sandy River Water Trail and many others detailed in the following sections of this summary. This report provides an overview of the planning process that resulted in the final, preferred Sandy River Park Master Plan. A summary of the inventory and site analysis is followed by a chronological look at the planning and design process, including the TAC and public workshops. A thorough description of the master plan and its components is included, with the cost opinion, public meeting summaries and other important supporting documents provided as appendices.

Constructed between 1941 and 1969, these structures function in collaboration to comprise the Willamette River Basin Reservoir System (WRBRS). The motivation for this project derives from a growing awareness of the biophysical impacts that dam structures can have on riparian habitats. This project compares each of the 13 dams being assessed, to prioritize their level of utility within the system.

  • Lower Columbia Chum
    Oregon Native Fish Status Report – Volume II Lower Columbia Chum Existing Populations This SMU consists of seven historic populations which are extinct (Table 85). This conclusion is supported by spawning surveys from the past several years. Ollerenshaw (2001) reported on chum spawner surveys from throughout the lower Columbia from the Youngs to the Columbia River Gorge tributaries. In 2001, after 79 surveys in 27 streams, no live or dead chum, and no chum redds were observed. In 2000, only one chum was observed in the South Fork Klaskanine River, and in 1999, more limited sampling yielded two live chum and one dead chum. A limited number of chum are captured at the Big Creek hatchery trap each year. Between 1990 and 2004, zero to 27 fish have been trapped annually. It has been proposed that recent chum returns to Oregon tributaries are simply stray chum returning as part of healthier runs to Washington tributaries to the lower Columbia. Loss or severe degradation of estuarine and lower river habitat has been implicated as a major cause for the extinction of chum runs in the lower Columbia River tributaries of Oregon. Table 85. Population list and existence status for the Lower Columbia Chum SMU. Exist Population Description No Youngs Youngs Bay tributaries. No Big Big Creek basin plus other Columbia River tributaries from Mill to (and including) Hunt Creek. No Clatskanie Clatskanie River basin plus Columbia River tributaries downstream to include Plympton Creek and upstream to include Beaver Creek. No Scappoose Scappoose Creek basin plus Columbia River tributaries downstream to Goble Creek and upstream to mouth of Willamette River.

  • The AOCC's Efforts to Log Protected Public Land
    The AOCC’s Efforts to Log Protected Public Land The Association of O&C Counties (AOCC) has supported and lobbied in favor of a controversial logging bill known as the Resilient Federal Forests Act (HR 2936), which would remove protections for public lands and waterways in Clackamas County and throughout Oregon. The AOCC has done media work to promote the legislation and in June of 2017, the President of the Association actually traveled to DC to testify before a Congressional Committee in support of this legislation. I. Threats to protected public lands in Clackamas County posed by HR 2936* Sec. 913 of the AOCC-supported bill would require all BLM forestlands, including 2.1 million acres of O&C lands, to be managed for the primary purpose of timber production. This provision would rescind conservation protections for the following public lands in Clackamas County and open these lands to logging: • Table Rock Wilderness • Salmon Wild & Scenic River • Clackamas Wild and Scenic River • South Fork Clackamas Wild & Scenic River • Sandy River State Scenic Waterway • Molalla State Scenic Waterway and recreation corridor • Wildwood Recreation Site • The Congressionally-protected Mount Hood Corridor (Clackamas County supported this legislation) • Sandy River Gorge Area of Critical Environmental Concern • Williams Lake Area of Critical Environmental Concern • Soosap Meadows Area of Critical Environmental Concern • Wilhoit Springs Area of Critical Environmental Concern • Areas designated as reserves for threatened species and to protect streams in the 2016 BLM Resource Management Plan Table Rock Wilderness *Note: Days before the bill passed the House, HR 2936 was amended to exclude Wilderness and Wild and Scenic Rivers from this logging mandate; however, the AOCC supported the original bill that would have removed protections for these areas.

  • CLACKAMAS COUNTY BOARD of COUNTY COMMISSIONERS Policy Session Worksheet
    CLACKAMAS COUNTY BOARD OF COUNTY COMMISSIONERS Policy Session Worksheet Presentation Date: 11/7/17 Approx Start Time: 1:30pm Approx Length: 60 min Presentation Title: Clackamas County Briefing -BLM Northwest Oregon District Department: BCS/County Parks & Forest Presenters: Jose Linares, District Manager, BLM – Northwest Oregon District; John Huston, Field Manager, Northwest Oregon District; Rick Gruen, County Parks & Forest Manager Other Invitees: Laura Zentner, BCS Interim Director WHAT ACTION ARE YOU REQUESTING FROM THE BOARD? Information and updates from the BLM Salem District Leadership Team EXECUTIVE SUMMARY: The Oregon and California Railroad Revested Lands, known as the O&C Lands, lie in a checkerboard pattern through eighteen counties of western Oregon. These lands contain more than 2.4 million acres of forests with a diversity of plant and animal species, recreation areas, mining claims, grazing lands, cultural and historical resources, scenic areas, wild and scenic rivers, and wilderness. Most of the O&C lands are administered by the Bureau of Land Management. The O&C Lands Sustained Yield Management Act of 1937 put the O&C lands under the jurisdiction of the U.S. Department of the Interior (BLM). The lands were classified as timberlands to be managed for permanent forest production, and the timber was to be sold, cut, and removed in conformity with the principle of sustained yield for the purpose of providing a permanent source of timber supply. The Act also provided for protecting watersheds, regulating stream flow, contributing to the economic stability of local communities and industries, and providing recreational facilities. BLM has recently completed its Draft Resource Management Plan for six (6) BLM districts in western Oregon.
