Balancing the Goals and Barriers • Allowing LID Technologies on Municipal Lands
• Engineering Standards • Reduced Road Widths with bioswales & enhanced vegetation do not
balance well with the snow operations or fire department concerns
• Parks Requirements • Parks provide a huge opportunity for LID measures, in bioswales, infiltration
galleries etc.
• Stormwater Management Credits
• Expedited Approvals

• It’s Not Our Fault – The Development Industry is Innovative
• Time may not be on our side – LID Implementation can add an additional approvals track to the timeline
• Pilot Projects – Important to gather data and provide examples of LID Technologies that
are successful
• Rules & Expectations Vary • Potential Conflicts
– Engineering / Planning / Parks / Operations / Political – The Municipality has to buy into LID or it cannot be successful
