Introduction and Terminology[edit]

A Stormwater Cycletrack is a new term for a street feature that integrates two types of systems: stormwater control measures (green infrastructure[1][2]) and a specific type of cycling facility called a cycletrack [3][4]. A new term is needed because of several emerging issues: the special nature of this type of integrated cycling and stormwater system, unique design challenges, the increasing popularity of separated bikeways and attention being paid to complete street[5] and stormwater designs in general.Cycletracks are also known in the US as separated bikeways, separated bike lanes, protected bikeways or Class IV bikeways (in California.[6])

Cycletrack Features[edit]

Cycletracks can come in several forms and types: one-way, two-way, street level, raised (sidewalk grade) and intermediate level. One of the features that all types of cycletracks have in common is some type of barrier or separation between the bikeway and the motor vehicle travel lanes. This separation provides protection for the cyclist from the motor vehicles and is the main feature that attracts “complete street” planners and users to this type of bikeway. The separation required by cycletracks also provides space for stormwater infrastructure and therefore an opportunity to implement sustainable drainage systems along with cycling improvements.

Stormwater Cycletrack Features[edit]

Stormwater control measures are also known as green infrastructure and low impact development practices. Streets with stormwater control measures are often referred to as green streets[7]. The City of Portland is a leader in green street implementation[8]. Pervious pavement systems such as permeable interlocking concrete pavers, pervious concrete and porous asphalt can be used to detain and infiltrate stormwater runoff on streets[9]. Bioretention systems such as stormwater curb extensions, stormwater planters and stormwater tree well filters can also be used to detain, treat and/or infiltrate stormwater runoff. Stormwater Cycletracks can use one or a combination of stormwater control measures to manage runoff.

Guidance Materials[edit]

Several organizations have recently issued guidance for designing separated bikeways that integrate stormwater treatment. The Massachusetts Department of Transportation has an excellent design manual [10] with graphic depicting both bioretention systems in the separation area and the parking strip area of the cycletrack design. The National Association for City Transportation Officials (NACTO) created the Urban Street Stormwater Guide [11] to provide information for roadway designers that incorporates sustainable drainage design guidance[12]. The NACTO guide has information on stormwater cycletracks (with one type called a "floating island planter")in Chapter 4 (Stormwater Elements)[13]. The Federal Highway Transportation agency has also created a Separated Bike Lane Planning and Design Guide [14]with examples of stormwater cycletracks such as on the Cultural Trail in Indianapolis[15].

Integration Types[edit]

Stormwater Cycletrack on Shellmound Street in Emeryville, CA

Stormwater Cycletracks use either: the separation/buffer area of the cycletrack (protected bikeway) to provide space for stormwater features (such as bioretention); or the bikeway surface itself to infiltrate runoff (such as pervious pavement); or a combination of those concepts to include green stormwater infrastructure in the design of the facility. Street trees and/or smaller plants can be used as the vegetation treating the stormwater. A recent study shows that cyclists prefer cycletracks with trees as the buffer between cars and the bikeway as opposed to other types of separation.[16]

Examples[edit]

The Indianopolis Cultural Trail has sections of Stormwater Cycletracks along its route. https://vimeo.com/channels/629479/66131674

The City of Oakland has a Stormwater Cycletrack on Harrison Street and Lakeside Drive with trees and cycle lane markings: Google map link

The City of San Marcos has a two-way Stormwater Cycletrack on Armorlite Drive with bioretention, trees and pervious pavement in the bikeway: Google map link

The City of Emeryville has two Stormwater Cycletracks: one on Shellmound Street and one on Christie Ave. Google map link

The City of Menlo Park has a two-way Stormwater Cycletrack on Chilco Street. Google map link
