    Site Concept/Inspirations:

    This site is a balance of nature and man - the inuence of one on the other. I have tired to naturalize the site- keeping themain stream where it is and building small pockets along it as an overow spot in a large storm event as well as an areathat can be a host to a beautiful array of plants and owers.

    Some inspirations came from other rain gardens, a natural feel is inspired by the use of boulders and cobbles through themain water-way. An integral part of my thought process was how to connect the house to this rain garden - so I suggesta dry-creek which allows for a similar vocabulary of rocks and boulders, softened by plantings but also an element whichhas its own identity and purpose in the site.

    The plants are primarily native and hardy to the are, deer-hardy and mostly a mixture of cool greens and blues with some

    hotter reds andyellows in the summmertime.

    Left: Collage of rocks and boulders that

    can be used to create a more natural feelon the site. The old rail-way ties could beupdated with a rock facade (middle row,far left) and replace the ties coming in andout under the bridge with rock walls. Themain channel of the creek would be linedwith cobbles to protect the area from ero-sion. Also there is room to help manage thedrainage of the bridge using a simple stone

    waterfall (bottom row, middle) which helpsto direct the water off the bridge and intothe stream. As part of the connection be-tween the house and stream - a dry creek(bottom right corner) could be installed tocontinue the sites vocabulary.

    Plant Zones:The planting zones arebased on which plants willbest survive in each typeof location. The wetlandplants will thrive in verymoist areas such as thecreek-bottom in the cobblestones. The woodlandplants are adapted to part

    sun and varying moistureconditions. The sun peren-

    nial group is more suitedto ornamental grasses andowers that will create inter-est all seasons. The use ofshrubs might be good toadd structure winter inter-est. There are some splashesof color - reds and yellowsto heat up all the coolblues and greens in the site.
