Historical Overview
HISTORIC CONTEXT STATEMENT The following is a brief history of Oregon City. The intent is to provide a general overview, rather than a comprehensive history. Setting Oregon City, the county seat of Clackamas County, is located southeast of Portland on the east side of the Willamette River, just below the falls. Its unique topography includes three terraces, which rise above the river, creating an elevation range from about 50 feet above sea level at the riverbank to more than 250 feet above sea level on the upper terrace. The lowest terrace, on which the earliest development occurred, is only two blocks or three streets wide, but stretches northward from the falls for several blocks. Originally, industry was located primarily at the south end of Main Street nearest the falls, which provided power. Commercial, governmental and social/fraternal entities developed along Main Street north of the industrial area. Religious and educational structures also appeared along Main Street, but tended to be grouped north of the commercial core. Residential structures filled in along Main Street, as well as along the side and cross streets. As the city grew, the commercial, governmental and social/fraternal structures expanded northward first, and with time eastward and westward to the side and cross streets. Before the turn of the century, residential neighborhoods and schools were developing on the bluff. Some commercial development also occurred on this middle terrace, but the business center of the city continued to be situated on the lower terrace. Between the 1930s and 1950s, many of the downtown churches relocated to the bluff as well. -
Timing of In-Water Work to Protect Fish and Wildlife Resources
OREGON GUIDELINES FOR TIMING OF IN-WATER WORK TO PROTECT FISH AND WILDLIFE RESOURCES June, 2008 Purpose of Guidelines - The Oregon Department of Fish and Wildlife, (ODFW), “The guidelines are to assist under its authority to manage Oregon’s fish and wildlife resources has updated the following guidelines for timing of in-water work. The guidelines are to assist the the public in minimizing public in minimizing potential impacts to important fish, wildlife and habitat potential impacts...”. resources. Developing the Guidelines - The guidelines are based on ODFW district fish “The guidelines are based biologists’ recommendations. Primary considerations were given to important fish species including anadromous and other game fish and threatened, endangered, or on ODFW district fish sensitive species (coded list of species included in the guidelines). Time periods were biologists’ established to avoid the vulnerable life stages of these fish including migration, recommendations”. spawning and rearing. The preferred work period applies to the listed streams, unlisted upstream tributaries, and associated reservoirs and lakes. Using the Guidelines - These guidelines provide the public a way of planning in-water “These guidelines provide work during periods of time that would have the least impact on important fish, wildlife, and habitat resources. ODFW will use the guidelines as a basis for the public a way of planning commenting on planning and regulatory processes. There are some circumstances where in-water work during it may be appropriate to perform in-water work outside of the preferred work period periods of time that would indicated in the guidelines. ODFW, on a project by project basis, may consider variations in climate, location, and category of work that would allow more specific have the least impact on in-water work timing recommendations. -
Apology to the Willamette River
AN ABSTRACT OF THE THESIS OF Abby P. Metzger for the degree of Master of Science in Environmental Science presented on May 4, 2011. Title: Meander Scars: Reflections on Healing a River Abstract approved: _____________________________________________________________________ Kathleen Dean Moore As Europeans settled the Willamette Valley in the 1800s, they began to simplify Oregon’s largest river contained wholly within state borders—the Willamette. The river lost miles of channels from dikes, dams, and development. Some channels vanished under concrete. Others became meander scars, or shallow, dry depression in the land where the river used to wander. Besides being a geological feature, meander scars are reminders of the wounds of progress and our attempts to control the river. Through a series of personal essays, this book reflects on whether something scarred can once again be whole. It explores a simple question with no single answer: How can we heal a river while healing our relationship to it? The book begins with the history of the Willamette, when it was wild and free, and then moves into all the ways we simplified and left it scarred. The story then reflects on what we might value in healing a river—values such as the complexity of the water’s many truths; values of memories and stories that hold the history of a landscape before it was degraded; and values even of grief and danger, which bring us closer to places in unexpected ways. The final reach of the book explores the role of restoration in healing the Willamette—whether working to repair the earth compensates for our misdeeds, and whether restoration is a reflexive act in which participant and landscape are both made anew. -
A Wild in the City Ramble Lowe R Willamette River Loop Sellwood Riverfront Park to Oregon City Fa Lls
Bike A Wild in the City Ramble Lower Willamette River Loop Sellwood Riverfront Park to Oregon City Falls Before setting out on this twenty-five-mile loop ride, Sellwood Riverfront Park 1 is worth a brief look. When I visited the site with Portland Park staff in the early 1980s, it was a heap of Himalayan-blackberry-covered sawdust, having once been an old mill site. It’s a tribute to the landscape architects who transformed a truly ugly landscape into a fine neighborhood park and a great place to access the Willamette. The funky little wetland feature in the park’s northeast corner, abutting the black cottonwood forest, has a short boardwalk from which you can see native wetland plants like spirea, blue elderberry, creek dogwood, willow, and wapato, and kids can catch polliwogs. Green heron sometimes skulk about looking for frogs, one of which is the rare north- ern red-legged frog (Rana aurora). From the park, I jump on the Springwater on the Willamette trail and head out to Milwaukie and the Jefferson Street Boat Ramp 2 , where there are great views of the Johnson Creek confluence with the Willamette River 3 and a distant view of Elk Rock Island. The route south is along the paved bicycle-pedestrian path that winds riverward of the Kellogg Creek Wastewater Treatment Plant. The short path abruptly dumps you onto SE 19th Avenue and SE Eagle Street. Ride straight south to SE Sparrow Street. All the streets in this quiet neighborhood are named after birds. At the end of Sparrow Street is the entrance to Milwaukie’s Spring Park 4 and access to Elk Rock Island. -
