Lawn Project at Kroeber Hall

Theron Klos, Operations Manager from UC Berkeley campus asked Blake Garden for assistance in replacing a thirsty lawn on campus near Kroeber Hall. Since we had experience with that kind of project here at the garden (see Lawn Project posting) we were happy to help. First we met with Theron for a mini charrette, a design workshop, to brainstorm about a new design for that area.  Attending were Blake staff, Landscape Architecture grad & undergrad students and UC campus grounds staff. After coming up with a design scheme, the real work began. Removal of the turf at the edges was done by UC campus grounds staff first.  The existing inefficient irrigation was then disassembled. The Blake crew,  made up of staff, volunteers, and work study students from the College of Environmental Design, came next.   Along with UC grounds staff we rolled out layers of cardboard over the grass to deprive it of sun and eventually  die out.  Next on top came a 1"  layer of compost, then 3" layer of mulch.  The new drip irrigation is ready to be installed and  finally  we will plant drought tolerant, mostly native, habitat friendly plants. A new path has been made and will be surfaced with permeable pavement- decomposed granite. It will be stable enough to hold up to  heavy foot traffic but will allow water to drain through capturing the water into the planting beds instead of running off and into the already taxed drainage system.
