East Liverpool, Ohio
Completed September, 1785
The Land Ordinance of 1785 required that U.S. lands in the public domain be surveyed before sale, and that the surveys be made in accordance with a consistent, integrated system of lines grid-oriented to a true meridian (north-south reference line) and base line (east-west reference line), subdividing the land into approximately square parcels, called townships.
Thomas Hutchins, the first Geographer of the United States, drove his stake near East Liverpool, Ohio to mark the Point of Beginning of the Geographer's Line, the first westward base line.
The surveys were required by the ordinance to begin on the Ohio River at a point that shall be found to be due north from the western termination of a line which has been run as the southern boundary of the state of Pennsylvania; This point was chosen because the southern boundary of Pennsylvania had just been surveyed, but the western boundary had not.

In a special summer UrbanPlan Scholars program, four teams presented their proposals for a six-acre parcel next to UH West Oahu. They had to address zoning requirements, affordable housing/workforce housing, rail/transit issues, agriculture, and energy.
UrbanPlan is a global competition run by the international Urban Land Institute. Hawaii schools have taken top honors in the global competition two years in a row, including Iolani School last month, and Iolani and Kalani two years ago.
Teams were made up of local high school students from Iolani, Kalani, LeJardin, MidPac, Punahou, and St. Andrews.
They conducted outreach to stakeholders and residents in West Oahu and found affordable housing to be the number one community need.
Ideas ranged from rooftop greenhouses and beekeeping to fully solar-powered facilities to integrating UHWO student and campus life.
Judges included Bob Harrison (FHB), Duff Janus (ASB), Brennon Morioka (UH), Mike Gabbard (Senate), Jim Houchens (Mitre), and Alana Kobayashi.
Bernice Glenn Bowers helped them plan for future high-tech industry in the area, doubled the size of the cash prize to $1,500.
Keokuk, Iowa
Completed 1913
Spearheaded by Hugh Cooper, the Keokuk Dam & Power Plant served as a prototype for many future power plants. The project harnessed the hydropower of the Mississippi River, between Keokuk, Iowa and Hamilton, Illinois.
The crest of the dam is nearly a mile long. The dam structure features 119 arch spans between six-foot-thick piers and a 110-foot-wide pneumatic lock. Combined with the lock, the dam reduced travel time for steamboats by nearly two hours.
This was the largest privately-funded construction project in the world when completed, and one of only two North American sites to generate 25-cycle power at the time.

New Orleans, Louisiana
Constructed 1875-1879
"Eads had to succeed in the face of conventional wisdom which doomed him to disaster. Entrenched authorities not only completely dismissed his theories, but pointed to the indifferent European experiences with what he proposed."
- ASCE Landmark Nomination Proposal, 1982
The mighty Mississippi River has long been a valuable lifeline for the country's transportation and commerce. In the late 1800s, though, the mouth of the ever-changing Mississippi was silting up, creating areas as shallow as eight feet. Eads South Pass Navigation Works opened a channel at the mouth of the Mississippi River that allowed large boats easy access to the Port of New Orleans.
James Buchanan Eads created a self-scouring channel through the South Pass by constructing wing dikes, perpendicular to current flow, which forced the current into a narrower cross-section. The current scoured the river bottom, pushing the silt far out into the deep Gulf waters. This created a nearly permanent channel that required only periodic dredging to maintain navigability.
The channel is no longer maintained for deep-draft traffic due to a decline in maritime shipping. But the principles which guided construction on the South Pass made possible the high performance of the Southwest Pass, currently the predominant seaward approach to the ports of New Orleans and Baton Rouge.
Facts
- A T-dam at the head of the South Pass deepened the channel. He used wing dikes, perpendicular to current flow, to force the current into a narrower cross section, thus scouring the channel more completely.
- Sill dams of horizontal timber were placed at the mouth of the river to force the current to further scour the channel.
- Once pilings had been driven, mattresses of interwoven willow branches were submerged and attached to the pilings. Then alternating layers of broken stone and willow mattresses formed the base upon which a railroad line was constructed.
- Initially, the project was completed with funds furnished by Eads and a group of investors. Only if the design succeeded would Congress provide reimbursement.

Comments always appreciated, as long as you keep it clean - I love to hear your feedback! xx
I went for a visit to Derby for their comedy festival and to spend the weekend with Gemma.
Saturday morning we went to Belper to the river gardens and the horseshoe weir, which is an incredible piece of civil engineering!
The gardens are lovely and tranquil. It was a great little alternative to our usual trip to Dovedale - which we called off because the weather wasn't great.
Had a lovely morning though!
Philadelphia, Pennsylvania
Completed in 1901
Philadelphia City Hall was the largest masonry load-bearing wall building in the world at the time of its completion in 1901, stood as the tallest occupied building in the United States until 1909, and still is the largest city hall in the United States. The building covers 4½ acres, originally contained 634 rooms with over 1 million square feet of space, and with its tower and statue of William Penn rises a total of 548 feet above the ground. The construction of Philadelphia City Hall began in 1872 and was completed in 1901. The bill providing for the erection of a new city hall passed both branches of the Pennsylvania State legislature in early April 1860, and the voters of Philadelphia selected Penn Square as the site of City Hall on October 11, 1870. The building was designed in the Second-Empire Mode of French Renaissance Revival architectural style by architect John McArthur, Jr. with the assistance of Thomas U. Walter, John Ord, and W. Bleddyn Powell.
The walls are brick, faced with white marble, and rise to a height of 337 feet above the ground. Not including the statue of William Penn, the tower rose 173 feet above the top of the building's masonry construction. The building measures 486 feet by 470 feet and rises seven stories high. The 18-foot 3-inch high basement story was constructed of white granite blocks that weigh from two to five tons and form walls up to 22-feet thick. The foundations of the tower rest on a bed of concrete 100 feet square and 8 feet 6 inches thick. The Tacony Iron and Metal Company hired civil engineer C.R. (Carl Robert) Grimm, M. ASCE to design the upper wrought-iron frame, metal-clad portion of the tower, which surmounted the masonry tower and supported the 37-foot-tall, 27-ton bronze statue of William Penn. The tower was designed to carry its dead load along with live loads on three floors and the balcony of 100 lb/ft2 and horizontal wind loads of 50 lb/ft2. The octagonal-prism tower designed by C.R. Grimm consisted of wrought-iron framework that supported the cast iron outer plates, which were electo-plated with copper and then covered with a finish coat of aluminum. The tower's pins and anchor bolts were steel.
