The National Park Service and St. Louis Mayor Francis Slay recently launched an international design competition to invigorate the park and city areas surrounding of one of the world’s most iconic monuments, the Gateway Arch in St. Louis.

The winning design will be announced in October 2010, with the resulting work completed by October 28, 2015 – the 50th anniversary of the completion of the Arch.

The competition – “Framing a Modern Masterpiece: The City + The Arch + The River 2015” – is called for in the NPS’s new General Management Plan, which was developed with extensive public input over an 18 month period, and finally approved on November 23.

The competition will invite teams to create a new design for the Arch grounds and surrounding areas with 10 goals in mind:

  • Create an iconic place for the international icon, the Gateway Arch.
  • Catalyze increased vitality in the St. Louis region.
  • Honor the character-defining elements of the National Historic Landmark.
  • Weave connections and transitions from the City and the Arch grounds to the Mississippi River.
  • Embrace the Mississippi River and the east bank in Illinois as an integral part of the national park.
  • Mitigate the impact of transportation systems.
  • Reinvigorate the mission to tell the story of St. Louis as the gateway to national expansion.
  • Create attractors to promote extended visitation to the Arch, the City and the river.
  • Develop a sustainable future for the Jefferson National Expansion Memorial.
  • Enhance the visitor experience and create a welcoming and accessible environment.

4 rivers project facing opposition from green groups

South Korea has recently had a ground breaking for a large scale remaking of the four major rivers known as the Han, Nakdong, Yeongsan and Geum. The project includes dredging of the rivers and construction of dikes, reservoirs and hydro-dams whilst creating parks, bikeways, and water recreation areas. This is a major undertaking by South Korea and its President Lee Myung-bak, Lee has a successful track record with rehabilitating rivers as it was during his term as Mayor of Seoul that the successful rehabilitation of 5.8km Cheonggyecheon River occurred.

The Four Rivers Project is expected to cost $19.2 billion USD and is expected to increase the water quality and flood control of the rivers which are somewhat polluted. 400 green groups have filed suit against the project to halt its progress based on environmental grounds including disruption to the ecosystem. The political opposition have joined with the green groups in opposing the project, however the government has countered that thorough environmental studies show minimal distrubance will occur and project will bring great economic benefits to the region.

European Green City Index – how green is your city?

Siemens recently published on their website the European Green City Index showing the results of a study conducted by the Economist Intelligence Unit.

Copenhagen was ranked #1 with Stockholm (2) and Oslo (3). Dense city centres such as Berlin (8), Paris (10) and London (11) scored high on the test. Cities that scored low where Sofia (29) and Kiev(30). These cities scored low as populations have increased and the economies have grown underinvestment in infrastructure has caused crowding on public transport and roads along with other factors such as climate which increase requirements for heating and cooling.
