On February 12, 2024 at 1:30 pm Cottage Grove held a pre-submittal meeting at Cottage Grove City Hall. The questions below were received during the meeting or through follow up emails. The following representatives were from Carollo, Ed Wicklein, Kurt Robinson, and Jaci Amend. Also in attendance was Ryan Retzlaff from Keller Associates.

Keller & Associates Questions

I asked about meeting DLDC and DEQ requirements. Faye you asked that I follow up so that you could address my comment/question. This is not a big concern of mine but want to make sure we understand the need so it can be incorporated into the plan. DLCD requires the Utility Master Plans be attached to the City’s Comprehensive Plan and be aligned with the land-use the plan allows. Answer; The Stormwater Master Plan will need to have a public hearing at both the Planning Commission and City Council followed by adoption by the City Council. Once approved it will be added as an appendix to the City’s adopted Comprehensive Plan. DEQ has approved grant and loan funding for this project. They will be given a copy of the Draft Stormwater Master Plan for their review and comments prior to City Council adoption.

It doesn’t sound like much of the data from the 2015 study is available. However, I would request that whatever data can be located that it be made available. I suggest a formal request to Carollo to send the city all files associated with the previous study might be helpful. Answer; City staff has looked for the data from the 2011 and 2015 study and unable to locate the data information. The City will make a request for that information after the Engineering firm is selected for the project.

I would like to see the flow data and associated rainfall data to verify it can be used to calibrate the model. Can this be made available? Answer; The US3 2022 flow monitoring report is attached and appears to have flow data for 4 storm water drainage systems including rainfall data. City staff was unable to locate data from the 2011 and 2015 draft master plans.

Can the current GIS be made available? This would also be very helpful to interrogate and review. Answer; We are currently working with the county and LCOG on other projects so are familiar with this team. The link to our current GIS is, https://experience.arcgis.com/experience/6ae522417f8a4c918f77c5e15c74ae5f When visiting the site you will need to open the Cottage Facility Data by clicking on the eye icon. The open the stormwater related eye icons.

I would like to formally request an additional week for the proposal due date which would put the due date on March 5, 2025. Answer; Yes, the City is extending the proposal due date to March 5, 2025 at 2:00 pm.

Carollo Questions

How many hard copies of the proposal are required? Answer; 4 hard copies of the proposal are required. Is an electronic version of the proposal needed? Answer; Yes.

Will LCOG electronically port all stormwater GIS data? Answer; Yes.

How current is the GIS data, is LCOG regularly maintaining and updating system information? Answer; The GIS data is as current. There are concerns with the accuracy of the older data as far as exact location. The Link to the City GIS is, https://experience.arcgis.com/experience/6ae522417f8a4c918f77c5e15c74ae5f

Several recent storm projects were noted, are they in the GIS or will design or as-builts be available? Answer; Design and as-built plans for recent stormwater improvement projects are available.

Will City crews perform CCTV as needed for condition assessment? Answer; Yes, City staff will be available to CCTV stormwater lines and verify pipe sizes.

Is utility rate analysis still a desired component of the plan, or will this be separately handled by another consultant under city contract? Answer; No, the City is under contract with Waterworth for preform rate analysis. City staff is also able to utilize the Waterworth financial software to determine utility rates.

Will the water master plan growth projections be the basis and available for storm system growth projection? Answer; Yes.
