Site Plan03/25/10Design and Disturbance.
March 25, 2010
To prepare the site for construction, topsoil is removed from the locations of the building and driveway footprints and from any areas of the site that will be impacted by construction equipment, vehicular circulation, crew parking, and on-site construction staging activities. This topsoil is then stockpiled in low berms scattered throughout the site, generally along the interior of the limit-of-work line, which helps discourage random vehicular access to areas outside the construction limit of work.  The berms are seeded with a cover crop of winter rye and mulched with straw to prevent erosion and retain moisture until the cover crop is established. The cover crop and mulch keep the stockpiled soil healthy, preventing desiccation and wind erosion, and maintaining essential microbial activity until the soil can be re-placed.
In many areas of the post-construction GO Home landscape, we plan to re-establish the field vegetation. Stockpiled soil was removed with the root systems of the existing grasses intact so where soils could be re-laid during the first season, the existing roots (still alive under the mulch and cover crop) re-sprout and the field re-grows. Healthy stockpiled soil will also retain the ‘seed bank’ of the pre-construction landscape, further aiding our efforts to integrate our landscape design with the surrounding ecological framework.
