Drainage Infrastructure Improvements Plan - February 2020

The City of Rollingwood contracted K Friese & Associates, Inc. (KFA) to perform a city-wide Infrastructure Improvements Plan to identify and mitigate local infrastructure concerns, with a focus on stormwater drainage and flooding issues. This plan provides potential mitigations for these issues and a summary of potential funding sources to guide the City’s development of a Capital Improvement Program (CIP). 

To identify drainage issues in the City, the project team spent the first half of 2019 gathering data by distributing a public survey, holding an open house, and reviewing drainage concerns and solutions that were documented prior to this plan. The team also conducted fieldwork, created a web-based geodatabase of existing infrastructure, and developed an inundation model to assess flooding depths and velocities within the City.  

Following the data collection and modeling efforts, the project team identified areas of interest (AOIs) and developed project concepts to address the highest priority issues. This final report includes summary sheets and cost estimates for these project concepts, as well as an analysis of potential external funding sources.
