CC Work Session 2. 4. Meeting Date: 07/31/2012 Submitted For: Len Linton By: Len Linton, Engineering/Public Works Title: Lower Rum River Water Management Organization (LRRWMO) - Implementation of Third Generation Plan New Development Requirements Background: City staff is requesting City Council's input regarding the LRRWMO's proposed implementation of the Third Generation Plan. The implementation measures include: 1. Permit Review Checklists 2. Collection of Sureties for Stormwater Management Facilities, Erosion and Sediment Control, and Shoreline or Streambank Improvement. 3. Stormwater Impact Fund 4. Volume Banking 5. Standardized maintenance agreements for storm water management facilities We would like to focus the discussion on items 2, 3 and 4 tonight. The LRRWMO is proposing the establishment of minimum performance sureties for activities requiring a LRRWMO Permit (see attached), and whether or not the amount would be consistent for all member cities. The minimum surety amount is proposed to be: For Stormwater Management Facilities: $6 per square foot for Infiltration Basins or Rain Gardens 125% of the construction and maintenance costs of all other facilities For Erosion and Sediment Control: $2,500 per acre disturbed plus $2.50 per linear foot of erosion control For Shoreline or Streambank Improvement: The greater of $5000 or $100 per linear foot of affected shoreline or streambank In addition, the surety is proposed to include 10% for contingency and 30% for administrative costs. The minimum surety required is proposed to be $5,000. The LRRWMO is considering some flexibility on whether the sureties would be collected at a WMO level or City level. The Stormwater Impact Fund would be established to provide a means for developers contribute an amount equal to $40,000 per acre of impervious surface for any unsatisfied portion of the volume control requirements of the LRRWMO. The volume requirements are summarized in Appendix E of the Third Generation Watershed Management Plan. The Volume Banking would be administered by the LRRWMO, developers of sites that create excess volume reduction may place the credits in the bank. Developers of sites that cannot fully meet the Volume Reduction requirements may purchase credits from the Volume Bank. Observations:
