16-0404 v3.0/Bike parking requirements for retail centre - Part 2

QUESTION

Our project is a proposed mixed-use retail centre containing a supermarket, specialty retail stores, liquor store, fresh food outlets, restaurants and casual dining outlets, gymnasium, child-care centre, medical centre and pharmacy. We request clarification on the requirements for bike storage, particularly on the building population that should be used as the basis for the calculation to determine the quantity of bike spaces. For a building such as our proposed mixed-use retail centre, the majority of the building's users will be visitors who spend not more than 1 hour at a time in the building. Also, given that the building is going to contain a supermarket, other retail outlets including a liquor store, and a medical centre and child care centre, a significant proportion of the building's visitors will be unlikely to be able to or feel comfortable to visit the centre on a bicycle because they will be: Leaving the building with bags or containers of groceries and other products that may be too heavy or bulky to safely carry on a bicycle; Unwell or injured; or Picking up or dropping off small children.
Based on this information above, we propose to provide a quantity of bike spaces as determined by the following methodology:
1. "Total Occupants" determined as the sum of:
- A) The number of building staff, and
- B) The number of peak building visitors (i.e. maximum number of simultaneous building visitors that occurs on a typical day), with a reduction factor applied based on the percentage of building visitors who are deemed to be unable to be able to cycle.
2. Bike parking facilities will then be supplied at a rate of 15% of (A + B) above. The reduction factor proposed in determining the number of peak building visitors will be determined at a later date based on operational data.  Please confirm if this approach is acceptable.  

ANSWER

The requirement for bike storage is to accommodate 15% of occupants unless there is a compelling reason not to do so. Project teams should include all project occupants that might bike in their calculations. For example, whether patients warrant a reduced rate would depend on the type of medical facilities: a hospital might justify a reduced number of bike racks, whereas a dental clinic would not. Hospital visitors (non-patients) should be included in the category of those who "might bike". For a pre-school, toddlers could be excluded from bike storage calculations, but a guardian would be included in peak occupant calculations (e.g. for drop off ), and older children would be included. A gymnasium included in the facility might warrant a slightly higher bicycle storage rate than the minimum of 15%.    

Note that project teams may take the timing of peak occupancy for different sectors of the building into account (i.e. if the store and the gym typically experience peak occupancy at different times, the team may use the time of day with the highest combined occupancy, rather than combining the highest occupancy for each venue no matter the time it occurs).
