Floodplain Mapping Presentation Nov 18, 2019

UPDATED Nov 20 – Added PDF of handout to end of article

As a result of the flood of 2018 a new set of floodplain maps needed to be created (the previous ones had been made in the early 90s). This is important for various reasons: Safety, Zoning Bylaws, City and Land Use Planning to name a few.

Previous mapping efforts employed the capabilities of the field at that time – and the results reflected that. New technologies such as LIDAR have improved the field significantly since then enabling a more precise data set. Coupled with advances in computer systems this has made the results of simulation modeling of water flow, and where it goes, much better.

Urban Systems has been a major participant in this process and on Monday Nov 18 two of their team, Senior Planner Joel Short and Professional Engineer Cameron Gatey, came out to present the results and discuss the ramifications to the town and its land-use-related laws.

In addition Recovery Manager Graham Watt, Mayor Taylor, some council members and city staff were present to help explain and answer questions.

About 50 people attended the event in the GFSS auditorium.
