Apex Pond Construction Complete!

The Apex Pond enhancement project in the City of Fridley is complete! Project planning began in 2022 with surveying, testing soils for on site contaminants, and design development. Construction began in fall, 2023 and spreading native seed and securing erosion control blanket over the upper slopes surrounding the pond were the final elements needed to complete installation. Originally constructed in 1999 with a ponding depth of one foot for rate control of runoff, the enhanced pond is approximately six feet deep and provides water quality treatment for nearly 90 acres of residential neighborhoods. The increased ponding depth enables sediment and nutrients to settle and accumulate in the pond basin.

Project Update: Apex Pond Enhancement

September, 2023 - De-watering of Current Pond, Tree Removal  
October, 2023 - Water Storage Capacity Increased, Plantings to Come

Construction of the Apex Pond enhancement project in the City of Fridley is nearly complete (see pictures above). The only remaining elements are to spread native seed and lay erosion control blanket over the upper slopes surrounding the pond. Apex Pond in the City of Fridley was originally constructed in 1999 to help control the rate of stormwater runoff entering Springbrook Creek from nearly 90 acres of residential neighborhoods. ACD, in partnership with the City of Fridley and the Coon Creek Watershed District (CCWD) identified an opportunity to enhance the water quality treatment capacity of Apex Pond by increasing the pond's storage volume.

Six New Rain Gardens in Fridley!

Construction is complete for six rain gardens at residential lots in the Rice Creek Terrace neighborhood in the City of Fridley. These rain gardens were placed at high priority locations to intercept and treat stormwater before it enters Rice Creek. The locations were identified during a Lower Rice Creek Stormwater Retrofit Analysis conducted by ACD in partnership with the City and the Rice Creek Watershed District. The rain gardens were funded by the RCWD's water quality cost share program and the City of Fridley. Landowners have all agreed to long-term maintenance of the gardens to ensure optimal and continuing stormwater treatment. 

Cumulatively, the six rain gardens are estimated to infiltrate 455,000 gallons of water, as well as remove 605 pounds of sediment and two pounds of phosphorus loading to Rice Creek annually. All six rain gardens are vegetated with native plants to maximize infiltration and provide the co-benefit of pollinator habitat. Additionally, one rain garden is located immediately adjacent to a trail entrance into Locke County Park, providing an excellent public education opportunity.

Over the next two to three years, the native plant plugs will get much bigger, filling the gardens with color and life. To see other rain gardens already installed throughout Anoka County, please see the virtual project tour on ACD's website. See photos of all six new rain gardens above.

Lower Rice Creek Stormwater Retrofit Analysis

The Rice Creek Watershed District (RCWD) contracted with ACD to complete a stormwater retrofit analysis for the purpose of identifying and ranking water quality improvement projects throughout select drainage areas to Lower Rice Creek in Anoka County. The report is in final review by the Technical Advisory Committee, and the final report will be completed by July 1st.

A total of 145 projects were identified throughout the 1,115-acre study area and generally consisted of rain gardens, underground sediment collection chambers, and stormwater pond installations or modifications. Potential projects were ranked in order of cost-effectiveness. The report provides a tool for natural resource managers when considering the implementation of projects to improve water quality in Lower Rice Creek.

The project is funded by RCWD and a Metropolitan Conservation Districts Clean Water Fund Accelerated Implementation grant.
