Glencoe Swale FIRM-Team update- June 7, 2017

Friends of Glencoe Swale met on June 7th.

Team member sharing:

Accuracy of the Flood Insurance Rate Map (FIRM) specific to Glencoe Swale watershed:

Our amateur hydrologist continued his musings. He described culverts from an historical perspective by sharing a series of local street maps from present day back to 1909. The quest was to understand a troubling culvert on Connell Street. Why is Glencoe culvert not a problem, but railroad and Connell Street culverts are? It turns out, Glencoe, then First Street, ended at city limits in 1909, however, Connell was the only road out of town at that time. It ran parallel to the railroad track. Thus, culverts at the railroad and Connell Street are both of undersized, antique quality.

Thoughts were also discussed about streamflow cfs measurements, and how interpretations can either decrease or increase the BFE (base flood elevations) in the area.

Storm water management research is underway. The team looked at diagrams to compare how drainage basins differ from the 1982 to 2003 state of development in Hillsboro. Changes make differences in how water moves through the basin. Port of Portland and Clean Water Services maps were used to track where the water goes. Work is continuing. Intel data is being sought to understand how water flow is affected by increases in paved areas within the Glencoe Swale area.

Impacts to real estate value and other property-related issues:

No new updates.

Outreach to all affected property owners:

A few visits were made door-to-door. Mixed reactions were given from not aware of being mapped into a flood zone to belief that flood premium is just the price of doing business here.

There is proof that we need to prioritize producing an information flyer to make community outreach easy and consistent.

Understanding financial aspects of flood premium determination:

No new update.

Communication with Washington County:

We are not the only ones who question the validity of the new FIRM map, and some of the data point that were applied in the mapping. Nor are we the only single homeowners in the County who were adversely affected by the FIRM adopted in November 2016.

Team Organization:

A template was reviewed that the team can use to assist in organizing our vision, mission, goals, objectives, strategic planning, time-lines, etc.  This will help the team move forward with pinpointing the “who, what, when, where, and why” of our project, and move us forward.

Next Steps:

Team members will continue working on tasks. Focus for June 21st meeting will be to share updates, and focus on organizational work time.
