(Unfinished Article) This is strictly a preview
The main view of this text is to frame the efficiencies of ecological cities and the efficacy of modern city design. This article is specifically about road-cutting, highways and streets, sidewalks, and everything else found within a concrete jungle, and how it all can support dynamic re-introductions of very useful plant species.
With a cities almost complete watershed, their is amazing options to utilize massive amounts of water. Hydro-cities of the future will manipulate water on buildings, in buildings, around buildings and within buildings or any complex structure. Sensitive enough instruments will not just be able to influence precipitation, but condensation and general humidity. Even now, smart buildings are being designed to catch, store and immediately use rain water, within itself, as insulation or for consumption.
Black and Grey Water
Black waste streams (poop…) will no longer be concentrated and chemically treated, but diluted and spread out within designed plants systems to be rapidly treated, biologically. With the use of very simple subterranean transport canals.
(Grey Water) Most homeowners would considerably benefit from recycling their greywater. Homeowners unable to install residential water loops, have the option to cooperate with other locals and government officials to establish localized water loops.
Urban Water Cycles
The many destructive floods throughout the California valley and many other parts of the world this past winter (2016/2017) have clearly shown, blatant ignore-ances towards properly founded city foot-prints. First solution will most likely be the upgrade and further development of every aspect of Californias’ water systems. Heightened embankments, demolished dams, repaired flood zones.
‘Daylighting’, aka deculverting, is just one example of steps cities are already taking to sustain their communities ability to hold and use water effectively. As well as curb cutting… and guerilla grafting of fruiting branches onto suitable host trees throughout city streets.
Besides residential food production, a cities water works can greatly aid key features of economy. Specialized salt-water canals offer passive transportation of heavy materials.
Constructed Wetlands and Rain Gardens…
Exporting water from urban centers to agricultural surroundings, using barometrically equavalent subterranean canals is by far, one of the most efficient methods of exporting excess rain water. The intake could be a large designed park within the city, acting as a drain for an entire locality (heart of storm drain networks).
Concrete Sidewalks: There are very few cases when concrete sidewalks are necessary.
Societal ‘Waste’: plastic and glass bottles, plastic bags, discarded electronics…
Roadways should always be ridge access, falling back to valley access in appropriate conditions, and countered hill-side access as last resort.
Hillside Road-Cutting: Obviously reshaping hillsides is a considerable amoints of work. Although it is apparently needed for some economic reasons (as compared to the longer distance of travel using ridges). Road-cutting must always be followed by immediate seeding of steep hillsides and any bare ground. Find tested seed mixes here
Roadway/River Intersections: These scenarios offer great potential for simultaneous societal and environmental development.
Culverts: Average culvert installations are no longer appropriate technologies for road construction. Although few cases have been observed where culvert construction seems sustainable (culverts are placed as usual, and then a ‘half-pipe’ segment of corrugated metal is used to ramp the draining water down to the ground at far slower pace). The water ripples over every little corrugation and reaches the ground with only a small fraction of the previous velocity.
Metropolitan afforestation is just as important as rural forestry. Homes with tree shade stay 20 degrees cooler in the summer. A healthy tree can increase property value by up to 27%. People will spend more money in shopping districts with trees than without.
