Multnomah County (the thirteenth in Oregon Territory) was created on December 22, 1854, formed out of two other Oregon counties – the eastern part of Washington County and the northern part of Clackamas County.

It is operated by librarians and library paraprofessionals, who are also Civil service, civil servants. There are five fundamental characteristics shared by public libraries: they are generally supported by taxes (usually local, though any level of government can and may contribute); they are governed by a board to serve the public interest; they are open to all, and every community member can access the collection; they are entirely voluntary, no one is ever forced to use the services provided and they provide library and information services services without charge. Public libraries exist in many countries across the world and are often considered an essential part of having an educated and literate population.

Concrete
Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. Concrete is the second-most-used substance in the world after water, and is the most widely used building material. Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminum combined. Globally, the ready-mix concrete industry, the largest segment of the concrete market, is projected to exceed $600 billion in revenue by 2025. This widespread use results in a number of environmental impacts. Most notably, the production process for cement produces large volumes of greenhouse gas emissions, leading to net 8% of global emissions. Other environmental concerns include widespread illegal sand mining, impacts on the surrounding environment such as increased surface runoff or urban heat island effect, and potential public health implications from toxic ingredients. Significant research and development is ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Bascule Bridge
A bascule bridge (also referred to as a drawbridge or a lifting bridge) is a moveable bridge with a counterweight that continuously balances a span, or leaf, throughout its upward swing to provide clearance for boat traffic. It may be single- or double-leafed. The name comes from the French term for balance scale, which employs the same principle. Bascule bridges are the most common type of movable span because they open quickly and require relatively little energy to operate, while providing the possibility for unlimited vertical clearance for marine traffic. History Bascule bridges have been in use since ancient times, but until the adoption of steam power in the 1850s, very long, heavy spans could not be moved quickly enough for practical application. Types There are three types of bascule bridge and the counterweights to the span may be located above or below the bridge deck. The fixed-trunnion (sometimes a "Chicago" bascule) rotates around a large axle that raises the ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Sellwood Bridge
The Sellwood Bridge is a deck arch bridge that spans the Willamette River in Portland, Oregon, in the United States. The current bridge opened in 2016 and replaced a 1925 span that had carried the same name. The original bridge was Portland's first fixed-span bridge and, being the only river crossing for miles in each direction, the busiest two-lane bridge in Oregon. The Sellwood Bridge links the Sellwood and Westmoreland neighborhoods of Portland on the east side with Oregon Route 43/Macadam Avenue on the west side. At its east end it leads to Tacoma Street. The bridge is owned and operated by Multnomah County. The original span of 1925 was a steel truss bridge, while its 2016 replacement is a deck-arch-type bridge. Original bridge Designed by Gustav Lindenthal, the first bridge opened on December 15, 1925, at a final cost of $541,000 (equivalent to $6.9 million in 2011). It was long with of vertical waterway clearance. It had four continuous spans, all of Warren type. The t ...

Ross Island Bridge
The Ross Island Bridge is a cantilever truss bridge that spans the Willamette River in Portland, Oregon. It carries U.S. Route 26 (Mount Hood Highway) across the river between southwest and southeast Portland. The bridge opened in 1926 and was designed by Gustav Lindenthal and honors Oregon pioneer Sherry Ross. It is named for its proximity to Ross Island. Although it looks like a deck arch bridge, it is a cantilever deck truss bridge, a rare type in Oregon. History and description The bridge was part of the unprecedented period of bridge building in Portland during the 1920s. It was opened on December 21, 1926, and cost $2 million to construct. The bridge was designed by a famous engineer named Gustav Lindenthal. The bridge is named for its location close to Ross Island, an island in the Willamette River which measures about one-and-a-half by one mile. The bridge is about 800 feet (250 m) north of the island and does not connect with, nor does it provide access to, Ross Isl ...

Gustav Lindenthal
Gustav Lindenthal (May 21, 1850 – July 31, 1935) was a civil engineer who designed the Queensboro and Hell Gate bridges in New York City, among other bridges. Lindenthal's work was greatly affected by his pursuit for perfection and his love of art. Having received little formal education and no degree in civil engineering, Lindenthal based his work on his prior experience and techniques used by other engineers of the time. Early life Lindenthal was born in Brünn, Austrian Empire, now Brno, Czech Republic in 1850. Lindenthal began to receive practical training in 1866 when he was employed as a mason and carpenter. At the age of 18, Lindenthal left his family to set out to make a life of his own in Vienna, Austria. Career When he arrived in Vienna he became an assistant in the engineering department for the Empress Elisabeth Railway of Austria. Two years later he joined the Union Construction Company, where he gained experience in building incline planes and railroads. ...

General Obligation Bond
A general obligation bond is a common type of municipal bond in the United States that is secured by a state or local government's pledge to use legally-available resources, including tax revenues, to repay bondholders. Most general obligation pledges at the local government level include a pledge to levy a property tax to meet debt service requirements, and holders of general obligation bonds then have a right to compel the borrowing government to levy that tax to satisfy the local government's obligation. Because property owners are usually reluctant to risk losing their holding from unpaid property tax bills, credit rating agencies often consider a general obligation pledge to have very strong credit quality and frequently assign them investment grade ratings. If local property owners do not pay their property taxes on time in any given year, a government entity is required to increase its property tax rate by as much as is legally allowable in a following year to make up for any ...
