slopes
When my client purchased a home at the top of a steep ravine, all she really knew was that she owned a lengthy stretch of a streambed and the land rising above it on both sides. At some point after she moved in, she decided to beautify the space, had a load of 200 boulders dumped in the driveway and hired her landscaper to move them down to dress up the waterway, which was dry through most of the year and was overgrown with all sorts of unwelcome plants. What she didn't know was that she was fooling around with Kenter Creek, a federally protected Blue Line waterway that started high in the hills a couple miles away. She had figured, reasonably so, that the stream was

On a big project such as the one we're covering in this video series, the rocks needed to give the cascades a natural look are quite substantial - some in the 36-inch range or larger, with weights rising to a ton or more in a few cases. Handling these brutes takes reliable equipment as well as distinct skill in working with
Some building sites are just tougher than others - and there are few of them that will complicate the construction process as much as the steep slopes discussed in the video linked below. To be sure, top contractors love these difficult sites: Not only do they give us the opportunity to incorporate nearby and distant views into our design vision, but they also
Have you ever noticed how often the costliest part of a project turns out to be something that will ultimately be hidden from view? This happens quite frequently in projects involving any sort of slope, where the piers and grade beams beneath swimming pools, for example, can cost far more than the rest of the overall project. In my own work, I’ve noticed this budgetary quirk most frequently when it comes to retaining walls, where providing the foundation they need to withstand the forces applied by a slope can be startlingly extensive and expensive. It’s not what you’d call glamorous work, but it certainly is important – and will vanish completely from view. Most often, we’re called on to build these walls when
Throughout recorded history, people have tried to control the elements in every which way they can. We plant trees to block the wind, build levees to hold back rising river water and dikes to hold back the seas. We build skyscrapers that defy gravity, winds and earthquakes. For all of this ingenuity, however, we sometimes don't do a very good job. When our efforts to control the elements fail on a large scale, we witness catastrophes that
Last time, we talked about planters, terracing and a couple other techniques for stabilizing slopes and making them look great as backdrops or foregrounds for hillside or hilltop watershapes. We left for this column the important discussion of what to plant in these spaces. In making these suggestions, I'll discuss soil-binding plants and other ground covers that contribute specific desirable qualities to landscape settings. My reasoning is simple: Although sod is a great ground cover and is certainly versatile, I believe that having a broader and more decorative
If you're in the business of digging holes, lining them with steel and concrete and then filling them with water, you need to know that the ground will support the structures. That's particularly true of hillside areas, but the same can be said of areas with high water tables, expansive soils or improperly compacted fill - to name just a few. We've all heard the horror stories of distressed vessels, including pools and spas out of level, significant structural shell cracks and differential movement between the decking and the shell. As we see it, part of the problem is that many pools are simply built with too low a structural tolerance for the stresses to which they
