This is the update the alders got yesterday. It includes a 30 minute video and “story map” presentation that seem somewhat useful. They talk about how they are going to spend the $775,000 in the budget on consultants, what solutions they might have and have tips for property owners at the end.
Here’s the video of a 30 minute explanation of what they are doing. (Again, sorry for the big gap, scroll down after the video – I can’t figure out what is doing that)
After they do the $775,000 studies and modeling, some solutions that they might do are:
– Improvement to pipe or inlet capacity
– System overflow modifications (safe overflow)
– Increase storage or detention upstream
– Low impact solution on private property to solve issue, such as landscape modificaitons
– High impact solution on private property to solve issues, such as structural change to building or building flood walls
– Acquisition of properties to be used for stormwater management and flood mitigation
– Public Works construction for flood repairs and mitigation projects
They will decide which solutions they will pursue based on this criteria:
– Cost/benefit ratio: the value of the properties damages will be compared to the cost of solutions
– Impact on emergency response routes
– How frequently flooding issues occur
– Independence of other downstream actions/flooding
– Improvements that mitigate downstream impacts
– Problems that are not a direct results of a property owners direct actions
– Areas with already-programmed work
– Within a Neighborhood Resource Team area
They are asking property owners consider doing the following:
– Self-Report online survey – www.cityofmadisonc.om/report flooding – this will help the city I.D. where flooding occurs.
– Understand drainage and how to protect your property
– Install back flow preventers and sump pumps
– Purchase supplemental insurance
ALDER UPDATE

Subject: Flood response and update for AldersHello Alders,
As all of you area aware, in the last few years and specifically on Aug 20, 2018, Madison and the surrounding areas have experienced extreme rain events. Most recently, the historic event in August resulted in extreme flash flooding and subsequent lake level rises and associated isthmus flooding.
Engineering is responsible for creation of an organized response to these flooding events. As part of that response, the Mayor and CC approved a large budget amendment with the 2019 budget to complete some flood reduction projects and to begin flood studies of many of the other problematic watersheds.
We will begin setting up Public Informational Meetings (see timeline below) for the watersheds that experienced the most significant flooding and in which we will be completing watershed and flood studies. In the interim time, we thought it would be helpful to provide you the following information and links to Engineering’s project websites as well as to our flood webpage which now features a voice over presentation and story map presentation to help get residents familiar with the flooding response. We hope that you are able to provide this information to your constituents in hope that we are able to keep them engaged and informed in this process. At this time we are only able to provide an overview of what has happened, background information on the process and some general timeframes on how the City plans to move forward.
Please keep in mind that a planned and managed response to these problems will take some time, additional budget appropriations and it is very likely some of the proposed solutions will not be popular to all residents. The outreach and information sharing as part of these studies, including any proposed mitigation solutions, will take well over a year to complete. Staff has assembled a RESJ team to work on the outreach and information sharing plan and will incorporate those recommendations into the watershed and flood study projects. Once we have our final reports we must then estimate, budget, permit and design in order to provide mitigation measures. Residents will likely feel this is an unacceptably long schedule but it is the most optimistic and yet realistic schedule we are able to provide.
If you have time we encourage you to take a look at the information and resources provided below. In particular we hope you will share the voice over presentation and story map presentation with those in your district. Our City IT team will also help promote this via social media and on the flood website email list.
If you have any questions please do not hesitate to contact us.

· Spring 2019 Budgeting general dollars for flood mitigation projects and continued watershed and flood studies.
· Summer of 2019 – Modeling and collection of calibration data
· Summer/Fall 2019 – Public Informational Meeting to provide preliminary findings
· Fall 2019 – calibration of modeling with data collected during the summer
· Potential budget amendments for flood mitigation projects prior to Council approval of Capital Budget
· Winter 2019/20 – Report results and list of potential solutions
· Winter/Spring 2020 – Public Informational Meeting(s) to report results and potential solutions
· Summer 2020 – Final watershed and flood studies to be completed

· Summer/Fall 2021 – Construction of flood mitigation first priority projectsSpecific timeframes for flood mitigation projects cannot be determined until a complete list of needed projects has been identified by the flood mitigation studies. The flood mitigation projects will take several years to complete and will be dependent on the Storm Water Utilities ability to fund them.
