Title
Discussion of the process to evaluate hazard mitigation properties and flooding/stormwater problem areas
Body
Action Required:
Guidance
Description:
The flooding of September 2009 prompted staff to focus on an evaluation of where the most significant problem areas are in the City. The goal is to create a document shared among all Departments that will identify stormwater problem areas and critical areas to be checked during inclement weather, and to establish priorities for action based on the extent of damages to our stormwater system, culverts, impacts to the floodplain and properties in the floodplain. A set of criteria will be developed for these evaluations as a guide for remedial decision-making.
Comments:
This analysis involves the collection of data from FEMA, rainfall data, evaluating data from the hydrology/hydraulic modeling from current floodplain mapping project (which is 60% completed), information from the stormwater system inventory and GIS. Interdepartmental collaboration will be sought for establishment of these criteria and creation of the planning document.
Staff will consider conditions such as existing flood hazard, vicinity to City property, property size, vicinity to other high flood hazard properties, etc., to identify the priorities. These priorities will guide decisions such as where to potentially acquire properties that have repetitive flooding/losses, how to prioritize capital funding for stormwater/flooding issues, and how best to improve water quality and protection.
