To create an accurate inventory and provide site-specific maintenance recommendations for green-infrastructure stormwater sites, Barr assisted the City of Minneapolis with developing an operations and maintenance manual and associated contracting documents. In one comprehensive manual, Barr documented separate maintenance and operations requirements and calendars for 26 green-infrastructure sites under multiyear contracts. The manual focuses on erosion prevention, sediment management, and plant-community management needed to maintain these stormwater features as attractive neighborhood amenities. It also provides procedures for maintaining seven types of BMPs. In addition, Barr created specifications for sediment removal and plant-community management and assisted the city with obtaining qualified contractors. The easy-to-read manual provides site managers with quick assessment methods and procedures for yearly evaluation and ongoing maintenance of BMPs.
