Board of Adjustment Meeting Minutes April 19, 2023 Page 10 of 11 Zuccaro begins his presentation by showing an aerial image for the Drainageway. This is part of the Goodhue Ditch and this is to replace a culvert. He discusses what a floodplain permit is and what the floodplain zone is. On a map, he shows the 100-year floodplain and the 500-year floodplain. He then shows an image of the construction documents. He discusses the pathways of the drainage and how that relates to the elevation. LMC Section 17.56.164 is discussed and says that an alteration of watercourse allows alternation of the watercourse subject to a CLOMR (Conditional Letter of Map Revision). Section 17.56.210 discusses the floodplain development permit procedures. Staff Recommendation: Staff finds that the request meets municipal code standards and recommends approval. Board Questions of Staff. Berger says you mentioned that there may be some areas that would be more impacted by flooding. Can you speak more on that? Zuccaro says within the floodplain report, there is a table. The existing flood elevation is 79.36 and after the culvert, there is an increase in elevation. Mapping that out in the topography, you can actually see the elevation going up and where that expands on the property. It is a pretty minimal expansion. Hawksley asks if this change will trigger re -assessment rates for homeowner insurances that back to this. Zuccaro says the insurance requirement only comes into play if it is affecting the structure itself. As long as the new flood map and new elevation is not hitting that structure. Flood insurance is only required if the floodplain is affecting the structure. Hawksley mentions his concern about homeowners receiving an increase insurance rate on their floodplain insurance and wonders the implication of approving this. Cooper mentions that her property touches the 500-year floodplain and she is not impacted structurally. Sommer asks if there are other floodplain maps not adopted by a government entity. Zuccaro says our floodplain maps were all updated in 2019 so they are all very current. He speaks more on flood insurance. There is nothing in the code about flood insurance. We see it as a benefit to remove structures from the floodplain since it eliminates risk. We do not require them to get insurance though. Hawksley mentions that there is one property that is in floodplain that was not before. Cooper says though that it is not a requirement to get floodplain insurance. Berger asks the number of properties that are in the floodplain and how that number would change after this adoption. Zuccaro says he does not know that number.
