- Preliminary designs were considered based of of the information gathered in the Fall. The group has decided to pursue an inlet-pipe system within the fire lane, a green roof on top of the proposed STEM building, and a type of porous surface between the proposed STEM building and Forcina Hall.
- The team visited Villanova and received a tour of various stormwater management sites from TCNJ graduate Amanda Hess and two other Villanova graduate students. We learned about various porous surfaces we can pursue for the design along with practical design possibilities for a green roof. We were able to obtain various geofabric and geotextile samples as reference along with a sample of the soil used in green roofs. Overall the trip gave us greater insight and direction on how to approach our designs for the proposed STEM building.
March
- Measurements of existing storm-sewer line were taken and NJ BMPs were researched in conjunction with the standards of other states and countries. The redesign of the storm-sewer line in the fire line relies heavily on NJ BMPs. However, for the porous surface (permeable pavers have been decided on) the BMP of North Carolina is being used in the design due to a lack of sufficient standards in NJ. For the green roof the United States has very little standards however, New Zealand has sufficient guidelines that have aided us in the design of a green roof.
- HEC-HMS has been used throughout the design process so far to determine which designs and which combinations of designs will provide the best mitigation of the stormwater runoff from various design storms up to 100 years.
