REQUEST FOR SERVICES Lake Amelia Subwatershed Management Plan Request The City of Lino Lakes, in partnership with the Vadnais Lakes Water Management Organization (VLAWMO), is requesting a scope of work and cost estimate from qualified consulting firms to conduct a Feasibility Study evaluating long term storm water management options for the subwatershed north of Lake Amelia. Background Information Lino Lakes is located in Anoka County, Minnesota, and is home to approximately 22,000 residents. Located in the southeast corner of the county and on the northeastern edge of the Twin Cities metropolitan area the community is a fast growing suburb. Lake Amelia is a natural environment lake, with a watershed area of approximately 754 acres. The lake lies upstream of Wilkinson Lake which is an impaired water. Purpose Drainage conveyance from properties lying north of Lake Amelia is provided by an existing private ditch which serves as an outlet for approximately 340 acres. There is no available information on the creation of the drainage system and it is not managed by a public agency. The ditch corridor and adjacent wetlands are identified as a proposed component of the City’s parks, greenways and trail system in the 2040 Comprehensive Plan. Lake Amelia is also identified as a lake of biological significance by the Minnesota Department of Natural Resources, due to a high quality colonial waterbird nesting area. The ditch corridor has seen recent flooding due to limited maintenance and failure of private culverts. This has raised concerns regarding long term management of the system as development pressure increases upstream. The purpose of the study is to: 1. Identify a preferred long term water quality and quantity management strategy for the ditch system. 2. Develop alternative concepts for BMP implementation along the corridor that enhances water quality, preserves flood storage and provides a potential recreational and wildlife habitat corridor. Scope of Work The Scope of Services should include the following: 1. Meeting with City and VLAWMO staff to kick-off the project and up to 4 additional
