Year action initially completed: 2019
Implementation details:
On October 7, 2019, the City Council adopted the City’s Met Council approved 2040 comprehensive plan laying out the vision for the Lakeville over the next 20 years. The plan includes a transportation chapter that is further subdivided to address specific types of streets and, specifically, pedestrian and bicycle trails and connectivity to City and regional amenities.
A goal for the plan is orderly expansion of Lakeville’s industrial parks through the logical extension of utilities to ensure local employment opportunities and a diverse tax base. Encouraging infill development that maximizes the return on existing investments in public facilities, infrastructure, and services.
The comprehensive plan addresses the importance of sustainability as an underlying theme for all elements in the plan. Local focus will be on maximizing protection and preservation of natural areas in Lakeville, providing infrastructure for electric cars, working to expand transit options both as part of the regional system and intracommunity options, expanding Lakeville’s system of sidewalks, trails, and greenway corridors both to promote healthy living and serve as an alternative transportation option, allowances for local food access, and access to solar energy.
Coincident with the adoption of the 2040 Comprehensive Plan, City Council also adopted the 2020-2024 Capital Improvement Plan (CIP) which was developed alongside the comprehensive plan. The Comprehensive Plan references the City’s Capital Improvement Plan that catalogs public investments by date and cost. Staff planning for capital improvements looks out a minimum of 10 years. The CIP is reviewed annually and updated to identify the City’s development objectives, infrastructure needs and allocation of financial resources providing City officials and the community with a strategic approach to implementation and administration of construction projects. The Planning Commission reviews the CIP every year for its consistency with the Comprehensive Plan.

Implementation details:
The City of Lakeville works closely with its neighboring cities and with both the Black Dog Water Management Organization and the Vermillion River Watershed Joint Powers Organization on surface water management issues and solutions.
In Lakeville, a 21-year involvement in the Citizen Assisted Monitoring Program allows the City monitor six lakes, Marion, Orchard, Kingsley, Valley, and East, on a bi-weekly basis to track water quality trends. Samples collected by local residents and staff are analyzed for various indicators of algae growth potential; surface water temperature and water transparency are also observed. This information provides the City with water quality data to use in properly managing surface water resources and serves to document water quality impacts and trends. Grades assigned by the Metropolitan Council are reported to the City annually.
The City also conducts annual studies on Marion, Lee, Orchard, and Valley lakes to monitor water quality, aquatic plants, and fish communities. The results are published annually to increase awareness of plant species and allow for a faster response to aquatic invasive species. Water reuse ponds a King Park are also included in this monitoring for chlorides, phosphorous, and bacteria to ensure that the water used in playing field irrigation does not harm aquatic organisms, promote algae growth, or adversely affect the recreational use of the park.
The City has also sponsored the Wetland Health and Evaluation Program since 2002 to provide educational opportunities and training for residents to collect data by using bio-indicators to evaluate wetlands throughout the City.

Efficient Water and Wastewater Systems {BP no.20}

3 star - Action 1:

Compare the energy use and financial performance of your facilities with other peer plants using standardized, free tools.

Date action report first entered:
Date of last report update:
Year action initially completed: 2016
Implementation details:
The City has entered energy use data into B3 Benchmarking for purposes of monitoring and managing energy use and for comparison with peer water production facilities. Energy use in a water treatment plant varies with weather and can be significantly affected by drought years. However, the treatment facility has invested in variable frequency drives on its high service pumps and has been able to reduce pump use to one pump for the majority of its needs. This has produced a saving in demand charges when starting up additional pumps to meet daily demand.
Outcome measures/metrics:
In comparing kWh per 1000 gallons in 2008 with 2016 there was a 7 percent decrease in energy consumption. During both years, the facility pumped 2.43 billion gallons and saw an approximate increase in electric rates of 15 percent over the intervening 8 years. The treatment facility is on a peak shaving program with Dakota Electric Association and receives a reduced commercial electrical rate.

Date action report first entered:
Date of last report update:
Year action initially completed: 2000
Implementation details:
The City has been active for the past 20 years in executing a rehabilitation program for each of is production wells. In addition, staff monitor the wells on a weekly basis for proper operation and to look for signs that the motor and pump are operating inefficiently. Indications of inefficient operation prompt immediate action and that well is taken offline and further evaluated for rehabilitation. Out of cycle rehabilitations are accomplished by delaying a well or another capital project scheduled in that fiscal year. Vertical turbine pumps are scheduled for rehabilitation every 8 years and wells with submersible pumps scheduled for rehabilitation every 10 years. One standby well is scheduled for rehabilitation every 13 years based on its infrequent use. A typical well rehabilitation removes the downhole pipe and the motor and pump. The motor and pump are evaluated and either sent away for refurbishment or replaced. The well is televised and any accumulated sand is removed to eliminate the potential for damage to the pump components.

2 star - Action 3:

Establish an on-going budget and program for decreasing inflow and infiltration into sewer lines and losses in drinking water systems.

Date action report first entered:
Date of last report update:
Year action initially completed: 2007
Implementation details:
The City has been active for the past 12 years in budgeting and executing a program for addressing inflow and infiltration within the sanitary sewer system. Initial efforts focused on televising and lining specific segments of pipe and sealing manhole structures that indicated the potential for, or were active in, allowing groundwater infiltration. As part of its inflow and infiltration mitigation efforts, flow meters were placed in areas considered most likely to produce higher sewer flows. Evaluation of collected data has allowed the City to televise and inspect specific sewer lines to monitor for both inflow and infiltration. In instances were inflow is suspected, the City approached the property owner to educate them on proper hookups for sump pumps and rain leaders. Subsequent years have seen a steady increase in the City's budget for inflow and infiltration mitigation and larger-scale projects to address issues throughout the City rather than being limited to a single area in any given year. Additional emphasis has also been placed on complete manhole sealing or rehabilitation to ensure that the structures do not contribute to the problem. The City also purchased a sewer camera truck to aid in the monitoring and management of the sanitary sewer system. The City is a participant in MCES grants for projects to mitigate inflow and infiltrations.
