Water from around the house is channeled to the North. Water draining to the North mostly sheets across the site to the Northwest corner. Water draining to the South collects in a central gulley and flows off site. Currently, all water quickly flows off site. BARLOW – PERMA ETHOS PDC DESIGN 2015 16 | P a g e At the South half of the site, the water flows across the site and collects in a central gulley before leaving the site as shown in the adjacent diagram. Most of the rain that falls will flow and collect along this route. The area shown in light blue will stay wet with standing and running water from late fall to early‐spring. Swales and ponds would be useful to both hold water on‐site and help alleviate the wet areas. As shown below, rain that falls on the stone parking area and behind the garage will flow around the elevated sand mound and off site before collecting in the main drainage route. A berm may be needed to keep this water on site. Approximately half the rain that flows to the North will collect in a gulley and flow off site near the end of the driveway. The remaining water will flow to the Northwest corner. The light blue area will stay wet with standing and running water from late fall to early spring. Here again, swales and ponds may be useful to keep the water on site and alleviate the wet areas. There is one isolated wet area shown below that also remains wet from late fall to early spring. Trees planted in this area die from wet conditions. Swales may be useful to keep this area drained. BARLOW – PERMA ETHOS PDC DESIGN 2015 17 | P a g e WATER CATCHMENT PLAN – See attached full size plan The water catchment plan calculates the surface area of the main drainage areas on the site. Potential swale and pond locations are used to divide the drainage areas and determine the amount of water that could be collected.

There is currently little protection from wind anywhere on the site. Windbreaks should be planted along the West and North sides of areas to be protected. SECTOR ANALYSIS – CLIMATE Cool Humid Temperate (Continental) Climate Zone – There are four distinct seasons. Winter is generally cold and wet with extended periods of time below 32 degrees F. Low temperatures reach 0 degrees F, the ground is snow covered about 30% of the time, and the ground freezes to a depth of 6”. Spring is generally cool and wet with temperatures between 50 & 70 degrees. Summer is generally humid and hot with limited rain. Temperatures range from the upper 80’s to low 90’s with short stretches in the upper 90’s. Rain is usually limited to afternoon thunderstorms and a 3‐4 week stretch of no rain is typical. Fall is generally cool and wet with temperature back down between 50 & 70 degrees. More often than not, a heavy dew or frost is present each morning. The consistent wetness appears to cause mold/mildew/fungus problems with apples, cherry, strawberries, cucumbers, melons, and other plants. The site is located at the foothills of the Appalachian Mountains. The Mountains are to the West and the land is relatively flat to the East. From the South, the Mountains basically run North until they reach Gettysburg and turn to the Northeast. This bend in the Mountains will actually reduce the amount of rainfall in the summer. Thunderstorm approaching from the West will actually split, pass by to the North and South, and then merge back together to the East. BARLOW – PERMA ETHOS PDC DESIGN 2015 19 | P a g e SECTOR ANALYSIS – VIEW The house is focused on a view to the North from a series of windows in the main living area. The view is open to the hills in the distance including Big Round Top, the high point in the battle of Gettysburg. SECTOR ANALYSIS – ZONES ZONE 1 – The Zone 1 area includes the house, pole building garages, parking, herb beds, and gardens. Future planned elements include trellis swing, firewood shed, water catchment tanks, greenhouse, nursery, and animal housing. ZONE 2 – There are three distinct Zone 2 areas to be developed into Food Forests. Food Forest areas will be concentrated around the swale and pond systems and include bee hives. ZONE 3 – Zone 3 areas will be left open and remain a grass pasture. The intent for Zone 3 is to create paddocks for grazing animals. ZONE 4 – Zone 4 is the area least visited on the property. Zone 4 will be developed into a Timber forest area. ZONE 5 ‐ None BARLOW – PERMA ETHOS PDC DESIGN 2015 20 | P a g e
