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
