An example of a green roof using a variety of plants
Currently, the City of Delaware does not treat its storm-water before discharging it into larger waterways due to its MS4 permit, which can lead to non-point source pollution. MS4 permits authorize cities, counties, or other governmental entities to discharge storm-water collected by their storm sewer systems to waters of the United States. This kind of pollution can augment to cause eutrophication or algal blooms, such as that which has occurred in Lake Erie. Ohio Wesleyan University (OWU) is located in a hilly location and a city that produces more rainfall per year than Seattle (38 inches versus 37.5 inches), creating the potential for relatively high levels of storm-water runoff. Installing a green roof to prevent polluted storm-water runoff is an example of executing best storm-water management practices and a practical solution for addressing the problem.
The aim of this project is to install a ~ 5500 sq ft green, sedum plant roof on the Delaware Entrepreneurial Center (DEC). This location is ideal because it is central to both OWU and Delaware. This project, initially proposed by the City of Delaware to manage storm-water, would benefit the student population, the university administration, the Delaware community, and the campus as a whole in multiple ways. Thus far we have investigated the feasibility of this project, researched its benefits, discerned key stakeholders and supporters, addressed safety and accessibility concerns, created a budget and implementation timeline, identified sources of funding, and considered maintenance planning.
These are mark-ups to show what a green roof at OWU could potentially look like
