Which of the following best describes the institution’s approach to rainwater management?:
A brief description of the institution’s green infrastructure and LID practices:
All new construction and major renovations on the Carleton campus, use the Green Globe principles as guidelines, these include Low Impact Development practices. In addition Carleton has policy guiltiness towards water reduction.
In addition, in the specifications of construction projects, a Sediment and Erosion Management Plan is created which includes requirements for reducing water runoffs.
A copy of the institution’s rainwater management policy, plan, and/or guidelines:
A brief description of the institution’s rainwater management policy, plan, and/or guidelines that supports the responses above:
Traditional collection and conveyance through underground stormwater pipes is currently the most common form of stormwater management on campus, and can increase the variety and amount of pollutants carried into waterways. Low Impact Development is an alternative form of stormwater management that mimics natural processes in order to protect water quality and associated aquatic habitat.
Low Impact Development strategies include bioretention facilities such as rain gardens and bioswales, green roofs, and permeable pavement. The following guidelines propose a number of Low Impact Development techniques to manage stormwater in open spaces on campus, and should be considered in tandem with water management for the construction of new buildings.
Carleton Goals and Guidance:
Reduce impervious surfaces where possible and maintain vegetative ground cover
Design stormwater management facilities to be functionally efficient and aesthetically pleasing amenities
Reduce potable water use for irrigation, and where possible, select drought tolerant plant species
Snow storage areas and impervious surfaces should be graded to drain towards permeable and semi-permeable surfaces.
Permeable paving should be used where possible in forecourts and courtyards, and in parking areas where feasible
Bioretention areas should be incorporated into pathway edges, parking lot design, and other paved areas. They should contain native and salt tolerant plant species that can thrive in a wet environment
Where possible, provide aquatic buffers along the Rideau River to manage sediment and nutrient runoff
Partner with the Faculty of Engineering to develop research and curriculum based learning opportunities
Include educational signage to increase awareness of stormwater management efforts and techniques
