Bayview Basin Reconstruction & Vegetation Cleanout RFP

The Chisago County HRA-EDA and the City of Center City is requesting proposals for basin reconstruction and vegetation cleanout services at the City Office and Bayview site. The scope of work includes berm repairs, sediment removal, and basin restoration activities for both the North and South Basins. In addition, the North Basin requires removal of a deteriorated, abandoned pipe.

1. North Basin Berm Repair (reference attached photos A & B)

• Locate, properly remove, and dispose of the existing abandoned corrugated pipe associated with the basin.
• Backfill the removed pipe alignment with appropriate approved fill material.
• Properly compact fill to prevent settlement and restore the area to match surrounding grades and conditions.
• Placement of topsoil over the reconstructed berm.
• Native seeding and installation of erosion control blanket on all disturbed areas.

2. North Basin Vegetation Cleanout

Work includes restoring basin capacity and functionality through vegetation management:

• Removal of accumulated sediment and all existing shrubs, plantings, brush, and overgrown vegetation within the basin.
• Importation and placement of sand and compost rain garden soil mix across the basin floor if needed.
