SLOPE ANALYSIS A building is best placed on a shallow slope because it still provides drainage while allowing for foundation to be laid with minimal land works required. It is also important to identify the steepest areas to start to dictate the easiest means of traversing the site. This entire site is sloping towards the river with varying steepness. There are approximately 6 areas of very shallow slopes that may be appropriate to build on.

COMPOSITE ANALYSIS
Floodway
One must first identify water features on, adjacent to, and near a site of interest. Once water has been located, one must keep in mind the probability of flooding in adjacent lands, including the 100- and 500-year flood plains that exist. One must preserve as much riparian zone as possible, as well as avoid any disturbance of crucial wetlands. Drainage is crucial, and natural swales should be taken advantage of. More than a third of this site is within various flood plains, so the high land in between natural swales is best.

In terms of hydrology alone, half of the site is not suitable for construction. Between the Olentangy River flood plains, the ravine that runs through the site, and the minimum 100 foot setback from any of these features, there are two segments of the site, one in each the north and south, that are realistically build-able . When further considering the steepest slopes, only two smaller areas within these larger expanses are really accessible. Next, when looking at views, all four are semi-realistic to build at. But, it considering the size of the building and the parking it will require, there is really only space for the entirety of the programming on the south site.

VIEWSHED When siting any building, one consideration is the views that building will have. Water and other natural features are popular to face, while other buildings, service areas, etc. are not pleasant views. On this site, there are two natural ridges that provide vantage points on the site, while the two high points theoretically provide the best views of the wooded site. In considering the north site, views of the elevation change on the south is another interesting view contender, while the ravine is another interest.

Soil is important in considering the build-able land of a site. Well-drained soils are best to prevent trouble with drainage. On this site, Eldean-Urban land complex is found on the highest elevations. It is well-drained and has at least 80 inches of depth before underground disturbances. Conversely, Ross silt loam is occasionally flooded, although well-drained otherwise, therefore it is not acceptable to be built on. This, again, identifies the high area as the most appropriate for building.

BUILDING SITING On the south site, there are two locations that are level enough to build and also accessible to traversing from the only access point. But, when considering the maximum efficiency of a parking lot, only the southeast corner really allows for maximum build-able area with a realistic route from the access road. In order to then site the building, it makes sense that it is places furthest back in the level area in order to leave room for parking and general maneuverability. By placing it on the ridge, the siting takes advantage of best drainage and views.
