Corrective Action 4.9.A The City of Hugo will implement the City of Hugo Water Resource Management Plan, follow MS4 permit requirements, and enforce City ordinances and associated watershed district rules. By following these requirements, the City will help reduce stormwater runoff rate and volume and provide an increase in the quality of stormwater runoff. Problem 4.9.113 RCWD has identified areas within the City with their Future Conditions Modeling that are prone to future flooding due to development. The City has reviewed and accepted the modeling results and identified issues listed below. 2C — JD #2 Main Trunk: This location was labeled as a relatively low problem likelihood. This likely showed an increase in flooding for the 2-year storm event and not and 10-year or 100- year due to the fact that the flows are strictly confined to the channel. No potential solution was identified. This location will be monitored by City staff on a regular basis to inspect channel conditions. Using inspection results, the City will be proactive in addressing any potential scour or erosion issues. • 100E — JD #2 Upstream of Elmcrest Avenue: This location was labeled as a high problem likelihood. The existing structure at 165th Street looks to be overtopped during the 100-year flood event. The City will consider a feasibility study to look at culvert replacement options at 1651h Street. • 100F — JD# 2 Upstream of Highway 61: This location was labeled as a low problem likelihood. The area currently provides a significant amount of flood storage and no structures are shown to be inundated. The peak flood elevation is shown to increase by less than a foot. The City will work with MnDOT and Washington County to address any concerns concurrently with future street or trail reconstruction projects • 100G — JD #3 Main Trunk: This location was labeled as a low problem likelihood. No structures are shown in the close proximity to the existing floodplain. Any future development will need to work with the City to address and mitigate any floodplain impacts and ensure structures are elevated to Rule E, City, and State standards. • 100J — JD #3 Main Trunk: This location was labeled as a low problem likelihood. This floodplain is not near any structures that could be inundated and is not shown to impact future development. Future development will be reviewed for floodplain impacts and will need to comply with City, State, and Federal floodplain standards. Corrective Action 4.9.113 This increase in flooding is caused by the added impervious that comes from new development. The City will work with RCWD on problem areas that are identified as having a high likelihood of occurring. The City will note these potential future problem areas and will continue to implement ordinances and RCWD rules to prevent them from occurring. The City will continue to maximize and promote infiltration and reuse opportunities to reduce stormwater runoff volume. Corrective actions listed above will also be implemented by the City. Problem 4.9.0 Through the development of North and East Groundwater Management Plan, the City of Hugo has been identified as located in an area of concern for groundwater recharge due to a high concentration of connection to surface waters and increase water demand from development. Corrective Action 4.9.0 The City have already completed and are pursuing numerous stormwater reuse projects for irrigation as part of new and existing developments. These projects help to meet the City's policy to reduce, reuse, and replenish surface and groundwater through stormwater management. Table 6-1 lists reuse projects that the City wishes to pursue over the next ten years. SECTION 4
