Thinking of Designing or Retrofitting? Here are some helpful tips!
In the City of Aspen, our goals are to reduce runoff and increase infiltration. When infiltration is prioritized and water is kept on site and allowed to permeate naturally into the ground, we reduce our pollutant load within the city's stormwater system and our local waterbodies. This simple methodology creates a healthier river with higher water quality for our recreation and aquatic life. Help keep Aspen beautiful by following these guidelines.
1. Consider stormwater quality needs early in the design process. When included in the initial planning for a project stormwater quality facilities can be better integrated into the overall site rather than being forced into the site as a late addition.
2. Reduce runoff rates and volumes to the maximum extent practicable. The objective is to more closely match natural conditions by placing stormwater in contact with the landscape, minimizing directly connected impervious areas, reducing the amount of impervious area (e.g., replace low-use or emergency access paved areas with porous pavement) and selecting treatment techniques that promote infiltration.
3. Consider surface conveyance as an alternative to pipes. Conveying flows on the surface is the best method for conveying runoff to porous landscape and porous pavement detention because it allows the facilities to be shallow. If flow can be conveyed on the surface in grass swales or in strips of modular block porous pavement, water quality will be improved becoming better for both the environment and the river.
4. Take advantage of the entire site when planning for stormwater quality treatment. Spreading runoff control measures or strategies over a larger portion of the site can help to reduce undesirable treatment strategies that detract from a site or are difficult to maintain.
5. Design attractive stormwater quality facilities that enhance the site, community, and environment. Consider surrounding land use type, context, prominence of the facility’s location on the site, and proximity of the site to civic spaces. Sustainable facilities provide positive options, especially in Aspen. Ideas such as Rain Gardens minimize disturbance, disruption and cost while creating an aesthetically pleasing and viable solution to stormwater design.
