The Watershed is seeking to experiment with spent lime as a method of capturing dissolved phosphorus in storm water runoff. The Parks and Recreation Commission will review the Watershed's proposal and provide a recommendation to proceed with the construction and monitoring of the basin. BACKGROUND The Watershed and the City are seeking ways to improve the water quality in Wakefield Lake. Maplewood has conducted a number of street improvement projects in the neighborhoods within Wakefield's subwatershed that contain boulevard rain gardens and large infiltration basins. These improvements address runoff from relatively newly (within the last 10 years) reconstructed residential streets. As well, Ramsey County constructed an off-line ponding basin on the south side of the lake in an attempt to treat "first -flush" flows from the main storm sewer outfall into the lake near the intersection of Prosperity Avenue and Larpenteur Avenue. This basin was an attempt to collect debris that discharges into the lake from the outfall. Due to the high volume of flow that comes through this outfall, the treatment basin is essentially over -used, and does not efficiently perform its intended function. DISCUSSION Phosphorus is the limiting nutrient in the development of algae in ponds and lakes. In excess, phosphorous can create algae blooms that utilize dissolved oxygen in water and, in turn, can cause anoxic conditions that can kill off living organisms within the water body. RWMWD is seeking to construct a ponding basin with what they term a "Permeable Reactive Barrier." Essentially, this is an experimental project to determine the effectiveness of using "Spent Lime" to reduce phosphorus in stormwater. Spent Lime is created by water utilities (e.g. St Paul Water Utility) and is a byproduct of the water clarification process. Spent Lime contains calcium, iron, and/or aluminum, all three of which bind phosphorus in the natural environment. Currently, Spent Lime must be disposed or transported for use on agricultural fields. Because of its high phosphorus binding capacity, the Watershed intends to experiment with spent lime as an agent to remove dissolved phosphorus in storm water runoff. This system will be constructed upstream and adjacent to the existing Ramsey County pond. As the water flows through the permeable reactive barrier containing the Spent Lime, spent lime will dissolve, bind phosphorus, and then settle in the pond. This will reduce phosphorus loads to Wakefield Lake. Because of the low cost, small footprint, and passive nature of the system, the Spent Lime permeable reactive barrier has wide ranging applicability to many storm water ponds. Agenda Item 5A IMPACTS RWMWD proposes to construct the basin in a wooded area up -slope from the existing sedimentation basin. The newly constructed treatment basin will have about a 42 ft by 20 ft footprint. This area has a steep slope and is not formally used as active park space. Modifications to an existing storm sewer pipe from Larpenteur and the large outfall will take place to divert water into the basin for the experiment. Because this is an experimental facility, RWMWD will also have monitoring equipment in the vicinity of the new pond. The experiment also has a limited duration of 2 years. However RWMWD staff will be on hand at the meeting to detail this further. The project will not encroach on existing park facilities such the nearby baseball diamond across from Presentation School. As well, the monitoring activities should not interfere with normal park operation and any monitoring/maintenance activities will be completed within normal park hours according to Maplewood Ordinance. BUDGET This project is 100% funded by RWMWD. They will also conduct all restoration activities associated with the construction disturbance. RECOMMENDATION Staff is supportive of the proposed project given the need to improve water quality within Wakefield Lake and the relatively small impact to Maplewood Park land. Staff is recommending that the Commission give a positive recommendation for the construction and ongoing monitoring of this experimental basin. Attachments: 1.
