As extreme weather events intensify and exacerbate flooding in urban areas, multipurpose urban squares can be used to detain stormwater during peak flow in a developed catchment. In this sense the Enghaveparken public park in Copenhagen adapts to dry – wet conditions and is capable to store 24,000 cubic meters of water before discharging at a controlled rate to the surrounding stormwater infrastructure.
The proposal titled “Urban Swales: Subterranean Reservoir Network for Los Angeles,” has been awarded 2nd place in Dry Futures Speculative category. Storm water enters each swale at the street corners where it is temporarily stored before beginning its gradual descent down through a cascade of phytoremediation terraces.
Dry Futures, An ideas competition seeking future-focused design responses to California’s drought, has announced winners and mentions. Liquifying Aquifer by Lujac Desautel, has been awarded 1st place in the Pragmatic category. The proposal asks: What if the Valley could have multiple drains placed around the city in contingent locations for maximum water replenishment back into the Aquifer?
A project for a public park in Medellín, Colombia that creates urban spaces around a series of water tanks to form a “socio-technical” landscape of magnificent beauty won the gold prize. The design opens up hidden infrastructure within the city to create a civic space at the intersection of architecture, landscape, infrastructure, and urban design. Continue reading
Porchscapes, in Fayetteville, Ark, is Habitat for Humanity residential LEED-Neighborhood Development pilot project that exhibits Low Impact Development (LID) standards under the Section 319 Program for Nonpoint Source Pollution of the U.S. Environmental Protection Agency. Designed by the University of Arkansas Community Design Center (UACDC), this proposal uses an ecological stormwater management approach to achieve primary goal: to manage all the rainwater via LID treatment train to retain and reuse all water that falls on the site.
The project titled Green Blocks – North Parks| by Erik Lomeland, provides an interesting and innovative solution to water reuse in the context of the urban block typology. Their idea (visible in the schematic water system diagram) addresses how water enters the building, is stored as greywater within the individual units and then distributed to the various green spaces. The team’s description: “Water Reuse – To protect our most precious resource, the water system makes use of grey water from sinks & showers for use toward toilets and gardens, adding redundancy to the water supply and draining less from municipal & natural resources.” This project was showcased in ResilientCity.org, a not-for-profit portal that focuses on developing the capacities for resilience in our cities to adapt and evolve.
In 2006, the partners of North Street Design were part of the winning team in the Urban Voids Competition. By combining two of Philadelphia’s civic problems – land vacancy and combined sewer overflow, the project team proposed a solution: using vacant land to create a network of stormwater parks that would alleviate the city’s hydrologic problems while generating new growth and development. The project is now a master planning and feasibility study in conjunction with the Philadelphia Water Department and Drexel University.
