Notice of Public Hearing

Riley Purgatory Bluff Creek Watershed District

Lake Riley Alum Treatment Project

 

PLEASE TAKE NOTICE that the Board of Managers of the Riley Purgatory Bluff Creek Watershed District will hold a public hearing consistent with Sections 103B.241 and 103B.251 of Minnesota Statutes, on February 3, 2016 at 7:00 p.m. at the District Office, 14500 Martin Drive, Suite 1500, Eden Prairie, MN 55344, to consider ordering the Lake Riley Alum Treatment Project. 

 

The District is proposing to implement an alum treatment program for Lake Riley in the context of a combined effort to address both internal and external pollutant loads to the lake.  An updated Use Attainability Analysis guides the coordination of a phased alum treatment with other best management practices to address external loading and thereby provide an integrated approach to restoring Lake Riley’s water quality and habitat.  In July 2015, the District received an engineer’s alum dosing study providing technical analysis and recommendations to ensure that the proper dose is applied, that the alum treatment is effective for the long term, that the treatment targets the appropriate phosphorus sediment pool, and that the treatment does not involve overdosing and excessive costs.  The dosing study provided treatment specifications, contractor selection, treatment monitoring and post application monitoring.  The District anticipates two alum applications over a two or three year period, as guided by monitoring results.

 

The initial cost estimate for this project is $50,000 for engineering (dosing study, project oversight and monitoring); and $500,000 (alum application).  The engineer’s July 2015 dosing study estimated the cost of the project for alum application, supervision, and monitoring to be $428,110. 

 

The project is proposed to be funded through the District’s ad valorem property tax levy to implement its watershed management plan pursuant to Minnesota Statutes Section 103B.241, 77% of which is paid by District property taxpayers in Hennepin County, and 23% in Carver County.
