landscape architecture


We've cried about structural engineers and spec'd overpriced retaining walls so it came time to be practical. A big thanks needs to go out to John Bodiford, Sr. Horticulturist of the SC Botanical Gardens for bursting the biggest Jeff and I had. Let's not beat around the bush, no pun intended, we were going to kill trees dead where they stand with the initial proposal for regrading the site. Two 18-24'' water oaks were on the chopping block, but I think we have saved the forest and tree huggers everywhere should celebrate. With the help of 500' of hot green string and a trunk full of 1x1 stakes, we have successfully taken over the site, created an interesting maze for onlooking children and found a way to preserve flat picnic areas, tree roots and amphitheater seating for the stage. After several hours and a few sore hammered thumbs on the site yesterday afternoon, Adam and I identified three terraced steps that can be reasonable created drawing from the hard lines of the stage and a few secondary entrances we are creating to the site. Following our discussion of threshold conditions, the landscaping will converse with both creek, picnickers, children at play and a performance volume of space yet to be defined. Rock faced gabion baskets abruptly meet the river to give a hard edge to the harsh line of modern nurturing and the feeder creek history. The threshold line becomes a conversation between what was and what is. The line bridging nature and community, demonstrating the unique opportunities both have to learn from each other. Linear axis pull the eye across the site and beg distraction to the greater, more subtle activity that moves through the grade, creek and shadows.

I think our newest design is the meeting of practicality and material possibility. Railroad ties will preserve an eco-footprint, lend to natural hues yet hold the soil for our purposes. With some strategic rebar anchoring, I believe we can retard soil movement and provide bench seating, observation levels, picnic platforms and even an audience for the stage. See a photo I found with some case studies of railroad terrace interventions. Our walls will no higher than 3', but the orientations is the same with a similar effect.

terraces, erosion control and you

After researching today, I think our best solution for erosion control in our terraced ampitheater will need to be completely covered with some type of coir blanket or geotextile. I really want to minimize the visibility of any installation in the contours to keep the design look natural so to avoid the manufactured appearance.

Monday I'm going to contact the Botanical Gardens for advice with vegitation options and erosion specific solutions to the climate and soil composition of our site.

Our group needs to move quickly to securing materials and pricing the work as our ground break is approaching quickly.

Surveys, Review Boards and Retaining Walls

This week has flown by with better progress than I had hoped. The group has begun to divide and concor and I think everyone has found interested in their responsibilities. The presentation could not have gone better on Tuesday night considering the state of disfunction we were just prior to walking into City Hall. I think we, as a group, now recognize the development that we need to have in order to move forward. Earlier, it was not always clear as to the next step in our process considering our inexperience with real worl design build applications.

Yesterday a faction of the Clemson crew surveyed the site in the dark. I don't even think Professor Sarasua thought we'd be idiots enough to try and survey our site on a cold Thursday...but we were, and we did. Our contour map will answer our questions about grading and fill needed for our landscape plan.

Today we talked about several differnt options for retaining walls since we can't use the recycled bottles or can bails. Initially I thought recycled aggregate would work, but a large concrete wall is not the aesthetic look we are designing for in this park. Jeff has found product data and researched gabion(loose rock walls contained in wire mesh) to use similar to the recycled bottle bails. From the structural diagrams and case studies on the interent, it looks like the cost and installation will be perfect for our application. I'm a little worried about the availability of some of these rocks in our area. As we researched, I remembered a vegitative wall in Madrid, Spain from my study abroad. Patrick Blanc, a french artist, designs vertical gardens on buildings all over europe and on a much simpler scale, I think the open cell design of these gabions will be perfect for some type of landscape intervention. My initial thought from some research was a berry of some sort to attract wildlife, but Jeff and I are both concerned with kids eating the berries...which would not be good. Either using some type of vine, planted in soil, built into the gabions, or fabricating pots that adhere to the mesh themselves, we could use the wall as a canvas to create shapes, messages or other designs...possibly with imput from students in the community.

I found this website that discusses all kinds of gardeing possibilities in retaining walls and with more research, I think some of the plants mentioned might serve us some good. Ultimately, I believe we might need to talk someone at the Botanical Gardens with suggestions of local plants that will accomodate our needs. Most sites seem to suggest the most important factor in design is the local climate.
