Any alternative must be approved by City Council. If it is your intention to utilize an alternative surface, you should articulate that to City Council. • Planting information for the rain gardens must be provided. At a minimum, the plan should identify species, quantity, size, and any other ground cover to be used within the rain gardens (hardwood mulch etc). • Other details/specifications for the rain gardens, such as pre-treatment chambers, should also be included on the plan. • A maintenance agreement will be required to ensure the long-term functionality of the rain garden. The City can provide a template for such an agreement should that be requested A service contract has been submitted; however, in its current format is not sufficient. • Please note that the City requires a two (2) year maintenance surety for all newly installed landscaping as noted in the draft Development Contract.
