Which of the following best describes the institution’s approach to rainwater management?:
Comprehensive policies, plans or guidelines that require LID practices for all new projects

A brief description of the institution’s green infrastructure and LID practices:

- Western is surrounded by the Upper Thames watershed and the Medway Creek. Significant amounts of Western’s property are on flood plain. We work closely with Upper Thames Conservation Authority for any new construction, renovation and site work. We abide by their policies and plans.
- Whenever possible, Western incorporates cisterns or retention ponds on its new construction projects, to aid in storm water management.
- Western has also started incorporating climate change adaptation planning. For example, in 2016’s work for the design of a new building near the Medway Creek, measures were taken to stay as far away as possible, as well as including a cistern and avoiding the construction of a basement.
- In 2016, Western developed the first version of its Sustainable Design Guideline, which addresses stormwater management for large, small and site projects throughout all of Western’s buildings and sites.
- The specific measures taken are assessed on a project-by-project basis, considering the site conditions, proximity to the watershed and the facility being developed.
- New constructions and major renovations are implementing diverse stormwater management techniques. All materials are being contained in bins to avoid the contamination of groundwater when it rains and at the new Richard Ivey Building, there are two sinks for water collection. The water runs into these ponds and from there they flow to the storm water drainage. Western regulates the flow of water going into the sinks by slowly releasing it, to avoid overflowing the capacity of the drainage system.

A brief description of the institution’s rainwater management policy, plan, and/or guidelines that supports the responses above:

- In 2016, Western developed the first version of its Sustainable Design Guideline, which addresses storm water management for large, small and site projects throughout all of Western’s buildings and sites.
- Strategies for rainwater runoff management have been implemented at the new Richard Ivey School of Business. The Richard Ivey School of Business features a rain water collection system that will allow for rainwater to be used to irrigate the landscape and flush toilets/urinals.
- The CMLP’s green roof is covered with flats of drought-resistant sedum, a hardy garden plant. The soil and plants insulate the building for sound, along with increasing the heating and cooling efficiency.
