Updated January 2025 – Gem Lake Consolidated Land Use Ordinance No. 131 121 <br /> <br /> <br /> <br />4. Alternative Compliance Sequencing. For sites where infiltration practices are determined infeasible as described <br />in Section 22.2.3.1, the following Alternative Compliance Sequencing steps shall be taken in the order shown: <br /> <br />1. Alterative stormwater compliance such as filtration or wet detention may be pursued. Supporting <br />documentation must be provided to justify infeasibilities. Alternative compliance must be designed to treat <br />the required volume as described in Section 22.2.2.2 and using criteria as listed in the most recent version <br />of the MPCA’s CSW Permit and Minnesota Stormwater Manual. <br /> <br />2. For linear projects, where the entire volume cannot be treated within the existing right -of-way, a <br />reasonable attempt to obtain additional right-of-way, easement, or other permission to treat the stormwater <br />during the project planning process must be made. If additional right-of-way, easements, or other <br />permission cannot be obtained, owners of construction activity must maximize the treatment of the water <br />quality volume prior to discharge. <br /> <br />3. For non-linear projects, where the entire volume cannot be treated onsite, owners of the construction <br />activity must identify locations where off-site treatment projects can be completed. Off-site treatment <br />must be selected in the following order of preference: <br /> <br />1. Locations that yield benefits to the same receiving water that receives runoff from the original <br />construction activity; <br /> <br />2. Locations within the same Department of Natural Resource (DNR) catchment area as the original <br />construction activity; <br /> <br />3. Locations in the next adjacent DNR catchment area up-stream; or <br /> <br />4. Locations anywhere within the permittee’s jurisdiction. <br /> <br />4. Offsite treatment projects must: <br /> <br />1. Involve the creation of new structural stormwater BMPs or the retrofit of existing structural <br />stormwater BMPs, or the use of a properly designed regional structural stormwater BMP. <br />Routine maintenance of structural stormwater BMPs already required by anoth er permit cannot <br />be used to meet this requirement. <br /> <br />2. Be completed no later than 24 months after the start of the original construction activity. <br /> <br />5. Maintenance and Easement. <br /> <br />1. Stormwater management easements shall be provided by the applicant for (1) access for facility <br />inspections and maintenance and (2) preservation of stormwater runoff conveyance, infiltration, and <br />detention areas and facilities, including the overflow route. <br /> <br />2. Land used by stormwater management facilities shall be preserved by dedication and/or perpetual <br />easement to the City, when required by the City. These easements shall cover those portions of the <br />property which are adjacent to the facility and which lie below the 100-year flood elevation. <br /> <br />3. A maintenance agreement shall be recorded with the County as part of the City development approval <br />process. Minimum requirements for the maintenance agreement include: <br /> <br />1. A list of the responsible party(s) (City and facility owner/manager); <br /> <br />2. Contact information; <br /> <br />3. A formalized maintenance schedule, with scheduled activities; <br /> <br />4. A “Failure to Perform” provision laying out remedial actions if the responsible party does not <br />perform as expected; <br /> <br />5. Maintenance debris handling plans; and
