For a watershaper who's spent a career designing and installing natural-looking ponds, streams and waterfalls using pumps and liners, this project was both an unusual treat and a distinct challenge - a dream job, as I saw it. I was called to the property at the suggestion of a landscape-maintenance company that wanted nothing to do with what the homeowners were asking, and the reason was pretty obvious: A spring-fed stream flowed across the property as it had done for at least hundreds and perhaps thousands of years, and it needed
We recently completed a project that truly thrilled a pair of well-traveled, highly educated clients: It was a large, complex waterfall-and-pond composition in the sloping backyard of an upscale home in an affluent southern California neighborhood. There were a number of reasons why the project worked so well, but if I had to break it down to one thing more than any other, it had to do with the range of edge treatments we used within the available space. On the side nearest the house, we established a clean lawn-meets-water detail – very disciplined in appearance and obviously man-made. Directly across the pond was a set of rugged waterfalls – much wilder and basically untamed. Bracketing those features, we filled shallow areas with emergent plants and hiding places for fish and frogs. It was a well thought out plan, certainly right for the space. But I know for a fact that
In 1921, a flood rolled into Pueblo, Colo., submerging the civic center beneath 11 feet of water and leaving more than 100 people dead. To prevent the recurrence of such disasters, engineers came to town, diverted the river along a different path and encased it in underground levees several blocks away. Seventy years later, a grand project known locally as HARP – the Historic Arkansas Riverwalk of Pueblo – undertook to restore the historic course of the Arkansas River and make it the centerpiece of a 26-acre downtown park. HARP re-creates 2,220 linear feet of the historic river in concrete-lined (yet naturalistic) channels. Nearing completion after ten years, the urban park will include 3,300 linear feet of navigable waterway for use by water taxis and pleasure boats as well as dramatic fountains; more than a mile of promenades and other walkways; a two-acre lake; and an outdoor environmental-education center. It has been a massive undertaking, as befits a project aimed at revitalizing an entire city. For the watershaping community, the project stands as an example of the truly transforming effect that
Now comes the fun part. The final stage of building a stream is where all of the planning and close attention to the stream's earthen substructure, transitions in elevation, liner alignment and hydraulics come into play as you move to build in details that effectively mimic nature. In the first two installments of this series (click here for part 1, here for part 2), I discussed in detail how you excavate and grade the site, place the major transition stones, lay in the liner and install
