Tryon Creek State Park
The Tryon Creek State Natural Area is a state park located primarily in Portland, in the U.S. state of Oregon. It is the only Oregon state park within a major metropolitan area. The park lies between Boones Ferry Road and Terwilliger Boulevard in southwest Portland in Multnomah County and northern Lake Oswego in Clackamas County and is bisected from north to south by Tryon Creek. To the north, the park abuts the Lewis & Clark Law School campus. Resources The park includes hiking trails, a paved bicycle path, and horse trails. The bicycle path, which runs along Terwilliger Boulevard on the east edge of the park to Lake Oswego, is part of the Portland metropolitan area's system of greenway trails known as the 40-Mile Loop. Near the main entrance off Terwilliger, part of the parking lot is devoted to horse trailers. Riders can choose between the North Horse Loop and the West Horse Loop. Hikers can use the bike path, the horse trails, and of hiking trails. The paved Trillium Tr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tryon Creek
Tryon Creek is a tributary of the Willamette River in the U.S. state of Oregon. Part of the drainage basin of the Columbia River, its watershed covers about in Multnomah and Clackamas counties. The stream flows southeast from the Tualatin Mountains (West Hills) through the Multnomah Village neighborhood of Portland and the Tryon Creek State Natural Area to the Willamette in the city of Lake Oswego. Parks and open spaces cover about 21 percent of the watershed, while single-family homes dominate most of the remainder. The largest of the parks is the state natural area, which straddles the border between the two cities and counties. The bedrock under the watershed includes part of the last exotic terrane, a chain of seamounts, acquired by the North American Plate as it moved west during the Eocene. Known as the Waverly Hills Formation, it lies buried under ash and lava from later volcanic eruptions, sediments from flooding and erosion, and layers of wind-blown silt. Two ...

Matching Fund
Matching funds are funds that are set to be paid in proportion to funds available from other sources. Matching fund payments usually arise in situations of charity or public good. The terms cost sharing, in-kind, and matching can be used interchangeably but refer to different types of donations. Charitable donations Concept In philanthropic giving, foundations and corporations often give money to non-profit entities in the form of a matching gift. Corporate matches often take the form of employee matching gifts, which means that if an employee donates to a nonprofit, the employee's corporation will donate money to the same nonprofit according to a predetermined match ratio (usually 1:1). For foundations, a matching gift is a grant made directly to a nonprofit on the condition that the nonprofit raises a set quantity of money before the grant is bestowed. The benefit of foundation matching grants is that they provide greater incentive leverage when a nonprofit is fundraising ...

Cordwood
Cordwood construction (also called cordwood masonry or cordwood building, alternatively stackwall or stovewood) is a term used for a natural building method in which short logs are piled crosswise to build a wall, using mortar or cob to permanently secure them. This technique can use local materials at minimal cost. Construction Walls are usually constructed so that the log ends protrude from the mortar by a small amount (an inch or less). Walls typically range between 8 and 24 inches thick, though in northern Canada, some walls are as much as 36 inches thick. Cordwood homes are attractive for their visual appeal, maximization of interior space (with a rounded plan), economy of resources, and ease of construction. Wood usually accounts for about 40-60% of the wall system, the remaining portion consisting of a mortar mix and insulating fill.Snell, C. & Callahan, T. (2005). Building green. Lark Books: NY.. Cordwood construction can be sustainable depending on design ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
