Authorize Stormwater Facilities Maintenance Agreement with DonFraco, LLC (Frana Wall Plant) EXECUTIVE SUMMARY City Council Meeting: August 20, 2019 AGENDA ITEM: Authorize Stormwater Facilities Maintenance Agreement with DonFraco, LLC (Frana Wall Plant) AGENDA SECTION: Consent PREPARED BY: Stephanie Smith, PE, Assistant City Engineer AGENDA NO. 6.g. ATTACHMENTS: Agreement APPROVED BY: LJM RECOMMENDED ACTION: Motion to Approve an Agreement with DonFraco, LLC for stormwater maintenance of the facilities at the Frana Wall Plant. BACKGROUND Please find attached for Council consideration of an agreement with DonFraco, LLC for maintenance of the stormwater facilities at the Frana Wall Plant located at 2785 160th Street. This summer, Frana Wall Plant received administrative approval for an expansion of their facilities. To comply with Rosemount’s Engineering Guidelines, they proposed constructing a private infiltration basin on their site. To comply with requirements of the City’s MS4 permit, the property owner was required to enter into an agreement for maintenance of their stormwater facilities, so they will continue to function as designed. This is a standard agreement used by the City when a private property constructs private stormwater facilities on their site rather than using a regional, public system. The agreement stipulates that the property owner, DonFraco, LLC shall provide utility as-builts, submit inspection reports, and perform maintenance on their private stormwater system. If the property owner lapses in their duties under this agreement, it authorizes the City to perform the work needed and assess the cost of such work against the property. RECOMMENDATION Staff recommends Council approval of the attached agreement with DonFraco, LLC for stormwater maintenance of the facilities at the Frana Wall Plant.
