6.b Scandia Water Resources and ImplementationVI. WATER RESOURCES A. Water Resource Goals and Policies Goal: Preserve and protect the quantity and quality of surface water and groundwater. Policies • Work cooperatively with all State and Federal agencies to comply with and enforce regulations and standards such as Shoreland Management Regulations, Erosion and Sediment Control Standards, Floodplain Regulations, and stormwater management. • Identify sensitive groundwater recharge areas and groundwater dependent natural resources to guide development and land use to minimize potential contamination and incompatible uses. • Require developers to restore the ability of soils to absorb, retain, and infiltrate water following site development. Goal: Improve stormwater management and land stewardship practices. Policies: • Provide educational resources and materials to residents and businesses regarding water quality, stormwater runoff, best management practices, and impaired waters. • Incorporate low -impact techniques and best management practices on City owned property. Goal: Protect the natural and scenic resources of the St. Croix River Corridor, both within and adjacent to the St. Croix National Scenic Riverway. Policies: • Work cooperatively with the National Park Service, Department of Natural Resources, and Carnelian Marine St. Croix Watershed District and adopt their Local Water Management Plans. Goal: Ensure financial and environmental accountability for installation, maintenance, remediation, and management of any permitted private wastewater system. Policies: • In cooperation with Washington County, enforce strict conformance with regulations for the design, installation, and maintenance of on-site treatment systems including minimum design, licensing, and installation requirements of the Minnesota Rules Chapter 7080. B. Wastewater 1.

Existing System The existing wastewater treatment system is comprised of several on-site septic systems and three small public wastewater systems. a) Private On-site Septic Systems Wastewater treatment for residents of Scandia consists primarily of on-site septic systems, shown in Figure XX. Washington County has record of 1,394 on-site septic systems in Scandia. Responsibility for installation and maintenance of on-site septic systems lies with the property owner. All systems must be installed and maintained to meet the standards for individual subsurface sewage treatment systems (ISTS) in Minnesota Rules Chapter 7080. The City of Scandia has delegated responsibility for septic inspections to Washington County. Washington County Ordinance 128, Section 17.2, requires owners of septic systems to have tanks pumped at least once every three years. Many lending institutions request inspections at the point of sale, and these inspections are recorded with the County. If Washington County becomes aware of non-compliant systems, the County requires replacement of those systems. Prepared by: Bolton & Menk, Inc.

Water Resources Scandia 2040 Comprehensive Plan Update I N13112739 Page 3 b) Public Wastewater Treatment Systems In addition to on-site septic systems, there are three public wastewater treatment systems in Scandia serving multiple lots and structures, shown in Figure XX. The operation, maintenance, and user charges for these public systems are governed by City of Scandia Ordinance No. 108. (1) Bliss Sewage Treatment Facility The Bliss Sewage Treatment Facility's treatment area is located on the western side of Big Marine Lake, off of Manning Trail North. The facility serves homes along Manning Trail North from the treatment area north to 191St Street North to the homes along Langley Avenue North, Layton Avenue North, Lamar Avenue North, and 185' Street North. It consists of three septic tanks totaling 7,500 gallons, three 15,000 square foot sand filters which are dosed by a lift station, and three drainfield trench cells (1,200 feet per cell) which are dosed by a second lift station. Based on drawdown tests performed in the spring of 2017, the two pumps in LS #3 (dosing the sand filters) have capacities of approximately 300 and 250 gallons per minute, while the pumps in LS #4 (dosing the trench cells) have capacities of about 110 and 190 gallons per minute. It processes an average of around 7,000 gallons per day during the winter months and 11,000 during the wettest summer months, but has a permitted capacity of 19,800 gallons per day. This system has had some issues with high nitrate levels in one of the monitoring wells surrounding the facility. Currently treatment options are being considered to mitigate this issue. (2) Anderson/Erikson Sewage Treatment Facility The Anderson/Erikson Sewage Treatment Facility's treatment area is located on the eastern side of Big Marine Lake at the southern end of Norell Avenue North. The system serves the homes along Norell Avenue North and those along 188' Street North to the intersection with Newgate Avenue North. The Anderson/Erikson Lift Station, which doses the drainfields, had pump capacities of roughly 65 and 70 gallons per minute, based on the 2017 drawdown tests. The drainfield system itself was originally designed to treat 6,700 gallons per day. Recent flows indicate that the system is treating slightly less than this amount, on average, but regularly exceeds this capacity during peak days and months of the year. Based on this information, the system is at capacity, and any other additions to it would require further examination to assess the system's capacity and potential for expansion. (3) Uptown Wastewater Community Collector System The Uptown Wastewater Community Collector System's Treatment area is located on Olinda Trail North, southeast of the village. The system serves Elim Lutheran Church and the parsonage, the Scandia Cafe, the Scandia Store, the Scandia Veterinary Clinic, the Country Messenger, the bank building, Schmitt Mall, the Community and Senior Center, and the Gammelgarden. The system was expanded in 1999 for the Community Center and again in 2001 for the Gammelgarden. In 2012 an equalization tank and an aerobic treatment tank, complete with blower and air diffuser, were added to the system to treat nitrogen and phosphorus in the wastewater. The trench drain laterals comprise 2,250 feet and 6,750 square feet of adsorption area. The average flow entering the system is 2,025 gallons per day and the peak flow is about 7,500 gallons per day. While the current system is an in -ground trench drain field, future expansions may Prepared by: Bolton & Menk, Inc. Water Resources Scandia 2040 Comprehensive Plan Update I N13112739 Page 4 require the installation of a mound system. The city owns land suitable for future expansion. Prepared by: Bolton & Menk, Inc. Water Resources Scandia 2040 Comprehensive Plan Update I N13112739 Page 5 Map: Existing Wastewater System On Prepared by: Bolton & Menk, Inc. Water Resources Scandia 2040 Comprehensive Plan Update I N13112739 Page 6 3. Capacity and Maintenance The Bliss treatment system could still accept some additional flow before it reaches capacity, around 6,000 gallons per day. However, the high nitrate level issues must be addressed, either by expanding the system or adding a focused treatment process to remove nitrate. The Anderson/Erikson system is essentially at its design capacity, and it should be evaluated before the addition of any more flow is considered. In general, it operates nominally under capacity during average flow, but above it during peak flows. The Uptown Wastewater Community Collector System is at 90% capacity. The city's future land use plan expands the Village Center area to accommodate residential and commercial growth. The City of Scandia owns land suitable for mound system expansion. For all of the systems discussed above, regular maintenance is key. Each of the systems has numerous of inspection pipes, which allow water levels to be monitored and blockages cleared in the drainfields. The tops of many of these inspection pipes have been damaged and/or the caps lost, either by accidental collision while mowing or other causes. This has the potential to allow dirt and debris into the system, causing blockages and issues, and these pipes require maintenance and replacement as needed. Additionally, animal encroachment, specifically gophers, have been noted in the vicinity of the systems. These should be dealt with regularly, as in their burrowing they can do a great deal of damage to this type of treatment system. In general, new development will need to provide for their own wastewater systems. The reliance on individual systems for future growth and development in the City will influence development densities and lot sizes. 4. Community and Subsurface Treatment Systems The City of Scandia's Development Code 13.14.2 states, "Where lots cannot be connected with a public sewer system, provision must be made for sanitary sewer facilities consisting of an individual disposal device for each lot. Such provision shall be in accordance with Chapter Four of the Washington County Development Code, Subsurface Sewage Treatment Systems Regulations. " Installation of individual sewage treatment systems into low swampy areas, drainage swales, floodplains or other areas subject to recurrent flooding is prohibited. Notwithstanding the foregoing, individual sewage treatment systems in existence may continue in use if they are repaired and maintained in conformity with the requirements of existing City and County Ordinances, and maybe replaced if normal repairs and maintenance to the existing system would not reasonably be expected to permit such system to operate in conformity with the requirements of existing ordinances. Individual Sewage Treatments Systems shall not be located within utility or drainage easements nor within dedicated public or private rights -of —way without proper approvals. The construction of community sewage treatment systems may be provided for all lots within a subdivision, providing they meet applicable MPCA and Washington County Health Department requirements and an entity other than lot owners or the City of Scandia can demonstrate capability of operating and maintaining the system. This may be done as an alternative to either individual sewage treatment systems or a public sewer system. Prepared by: Bolton & Menk, Inc. Water Resources Scandia 2040 Comprehensive Plan Update I N13112739 Page 7 Subsurface sewage treatment systems in the City of Scandia are also subject to regulations in Chapter Four of Washington County's Development Code, adopted in 2015. C. Surface Water 1. Background The City completed its Surface Water Management Plan (SWMP) and it was adopted in (DATE PENDING). The plan serves as a comprehensive planning document to guide the City in conserving, protecting and managing its surface water resources. The plan was developed to meet the requirements of Minnesota Statutes 103B and Minnesota Rules 8410, to be consistent with the goals and policies of the Metropolitan Council's Water Resources Management Policy Plan, and the goals and policies of the three watershed management organizations that have jurisdiction within the City. The plan and its amendments will be by the City as an element of this Comprehensive Plan. The SWMP includes a detailed description of the City's natural resources, including water resources, past studies and inventories, and current surface water management. An assessment of the existing and potential water resource and stormwater related concerns within the City and associated corrective actions are provided. The SWMP also includes goals and policies to address the long-term surface water management needs in the City, and outlines the regulations, standards, practices, projects and funding that will be needed to implement the goals and policies. The lakes and other critical environmental features in Scandia are one of the reasons the city is an attractive place to live. However, residential development on and near these lakes can impact the water quality and wildlife habitat if not properly managed. One of the primary concerns is the impact of impervious surfaces on water quality. In order to protect lakes from the negative impacts of development, federal, state and local authorities have established rules that protect natural resources against the impacts of development. The City of Scandia is generally subject to the following regulatory authority and strategic plans. • City of Scandia 2040 Comprehensive Plan • City of Scandia Ordinances • Carnelian Marine -St. Croix Watershed District, Watershed Management Plan, amended 2015 • Comfort Lake -Forest Lake Watershed District, Watershed Management Plan, 2012-2021 • Rice Creek Watershed District, 2010 Watershed Management Plan, updates in 2018/2019 • City of Scandia Comprehensive Plan Update, 2018 • City of Scandia Development Code, 2011 • City of Scandia, Shoreland Management Regulations, 2007 • Washington County Groundwater Plan, 2014 • Washington County Model Groundwater Rules, 2004 • North and East Metro Groundwater Management Area Plan, 2015 • Minnesota Department of Natural Resources North & East Metro Groundwater, 2015 Management Area Plan Prepared by: Bolton & Menk, Inc. Water Resources Scandia 2040 Comprehensive Plan Update I N13112739 Page 8 2. Watershed Management Organizations Scandia is located in three watershed districts: Carnelian Marine -St. Croix, Comfort Lake - Forest Lake, and Rice Creek. This section briefly describes the most recent local water management plan for each of the three watershed districts within the City of Scandia, followed by a comparison of the goals, objectives and policies of each plan. Management districts and subwatersheds are also noted. Subwatershed plans provide more geographic and issue specific management within the larger watershed. Figure xx shows the watershed management organization boundaries within Scandia. Carnelian Marine -St. Croix Watershed District, Watershed Management Plan, 2015 About 78% of the City of Scandia falls within the CMSCWD, encompassing the eastern and southern halves of the city. The Carnelian Marine -St. Croix Watershed District's (CMSCWD) most recent watershed management plan was created in 2011 and was amended in 2015 to better address invasive species and groundwater quality. The plan contains the goals, policies and management plans of the CMSCWD and guides the watershed's activities until 2020. CMSCWD also developed individual lake and stream plans for all waterbodies in the District. The plan includes a Focused Watershed Management process based on three levels of activity: Routine Watershed Management for the non -impaired water resources of the District—these are the basic, day-to-day programs implemented throughout the District. Impaired Watershed Management for water resources that are classified as impaired waters—includes completion of TMDL studies for impaired waters and implementation of the recommendations from these studies Focused Watershed Management for non -impaired waters—includes efforts to protect non -impaired waters so they do not become impaired, by enhancing routine management activities on identified water bodies. CMSCWD completed a district -wide Wetland Management Plan in July 2010 and amended the plan in September of 2015. An electronic version of the plan is available on the District's website. The plan includes a wetland function and value assessment, wetland management goals, management standards, buffer standards, and identification of Wetland Preservation Areas within the District. Based on the functions and values assessment, the plan includes a wetland classification system with four categories. The categories include: • High Quality/Highest Priority • Stream Corridor and Shoreland Wetlands • Isolated Wetlands • Utilized Wetlands Comfort Lake -Forest Lake Watershed District, Watershed Management Plan, 2011 The northwest quadrant of the city falls within the Comfort Lake -Forest Lake Watershed District (CLFLWD). Drainage from the watershed enters the Sunrise River, a tributary of the St. Croix River. The CLFLWD's most recent watershed management plan was created in 2011 with revisions adopted and approved by the BWSR in August 2015. The plan contains the goals, objectives, and actions of the CLFLWD and guides the watershed's activities until 2021. Prepared by: Bolton & Menk, Inc. Water Resources Scandia 2040 Comprehensive Plan Update I N13112739 Page 9 The CLFLWD plan has eight core goals areas: • Floodplains • Lakes • Streams • Wetlands • Uplands Resources • Groundwater • Public Education • Interagency Coordination Most of Scandia within the CLFLWD falls within the Bone Lake Management District. A small portion of the city (northwestern most corner) belongs in the Little Comfort Lake Management District. CLFLWD developed a Total Maximum Daily Load (TMDL) plan for Bone Lake, discussed below in the section on Impaired Waters. The District completed a Partially Drained Wetland Assessment in 2014. Rice Creek Watershed District, Watershed Management Plan, 2010 (amended 2016) The Rice Creek Watershed District's (RCWD) most recent watershed management plan was created in 2010. The plan contains the objectives, policies, and management strategies of the RCWD and guides the watershed's activities until 2001. Only 0.2% of the City of Scandia falls within the RCWD. This area encompasses all of White Rock Lake and is part of the Hardwood Creek Planning Region. The primary issues within the Hardwood Creek Planning Region are related to water levels within Rice Lake, the lack of a well-defined regulatory floodplain along the Hardwood Creek, and appropriate management methods for Hardwood Creek and its riparian corridor. The RCWD's 2010 Watershed Management Plan has 8 objectives: • Increase knowledge, awareness, and capacity for decision-making among District constituents • Manage water systems for their ecological and community value while • Recognize the origin and interconnectedness of water systems while planning for current and future needs • Improve diversity and ecological integrity of wetlands • Minimize damage to infrastructure and property caused by flooding and excessive runoff • Capitalize on open space opportunities to enhance water quality, reduce runoff volume, and enhance ecological resources • Incorporate groundwater into the decision-making process • Manage District property and resources responsibly Prepared by: Bolton & Menk, Inc.

Physical Environment and Land Use Public waters are all water basins and watercourses that meet the criteria set forth in Minnesota Statutes, § 103.005, subd. 15. Of the many wetlands and water bodies within the city's boundaries, 40 of them have been classified as public waters in accordance with the guidelines of the Minnesota Department of Natural Resources. Public waters within Scandia range in size from 2 acres to nearly 2,000 acres of water surface and include several water bodies of regional significance. Table 13 provides information on all public waters and their acreage. The St. Croix River, a Federally - designated National Scenic Riverway, forms the eastern border of the city. Big Marine Lake, in the southwestern portion of the city, is the second largest lake in Washington County. Existing and future development in areas surrounding public waters should be carefully managed and planned to prevent adverse impact on water resources.

Based on the NWI data, the City of Scandia has approximately 2,900 acres of wetlands based on the NWI data. Additional wetland information is summarized in the City's Surface Water Management Plan and the CMSCWD Wetland Management Plan (2015). b) Existing and Future Land Use: While Scandia allows for a variety of land uses, development densities are low to maintain the rural character of the community and to be compatible with agricultural uses. Residential development densities range from 0.1 to 0.4 units per acre. Commercial, retail, and industrial land uses are guided to be near existing infrastructure, including water and wastewater services. Likewise, the city anticipates a majority of residential growth to occur in and around the Village Neighborhood Zoning District, which is primarily centered around the historical city center. The Village Neighborhood Zoning District encompasses Goose Lake and borders the western shore of Big Marine Lake. The expansion of the Village Neighborhood Zoning District will reduce the amount of land zoned for agriculture or rural densities (4 units/40 acres). Low densities will be maintained to accommodate agriculture. Comprehensive land use descriptions can be found in the Land Use section of the Comprehensive Plan. 4. Existing and Potential Water Resource Related Problems In 2015, 12 lakes in or partially located in Scandia were monitored as part of the Metropolitan Council's Citizen -Assisted Monitoring Program (CAMP). In this program, lakes are sampled every two weeks from mid-April through mid-October. During each sampling, temperature, dissolved oxygen, and Secchi depth transparency were measured and recorded. A surface water sample was also collected and analyzed for total phosphorus, Prepared by: Bolton & Menk, Inc. Water Resources Scandia 2040 Comprehensive Plan Update I N13112739 Page 13 total Kjeldahl nitrogen, and cholorophyll-a. Total phosphorus is a key measure of lake nutrients, chlorophyll -a is a measure of algae abundance, and Secchi depth transparency is a measure of water clarity. The Metropolitan Council uses the monitoring data to assign each lake a water quality grade using an A through F grading system. The grading system uses percentile ranges for three water quality indicators -summertime average values for total phosphorous, chlorophyll -a, and Secchi depth transparency. An overall grade is calculated as the average grade for the three individual grades. The individual grades given to the lakes can be seen in Table 14. Five of the monitored lakes yielded insufficient information, five were given a "C" grade, none were given a `B" grade, and two lake received an "A". Table 14 — CAMP Ratings for Lakes Within Scandia Lake Rating Alice Insufficient Data Big Marine A Bone C Fish Insufficient Data German Insufficient Data Goose C Hay Insufficient Data Jellum's Bay C Long B Sand C Sylvan A White Rock C Under the federal Clean Water Act (33 U.S.C.) the Minnesota Pollution Control Agency (MPCA) is required to set standards and assess Minnesota waters for impairments. The standards are set on a wide range of pollutants, including bacteria, nutrients, turbidity, and mercury. A water body is listed as impaired by the MPCA if it fails to meet one or more water quality standards. If a water body is listed as impaired, a Total Maximum Daily Load (TMDL) must be established for the pollutant, and plans must be created to reduce TMDLs. Scandia will be required to participate in TMDL plans for impaired water bodies within its borders. Figure XX shows the locations of impaired water bodies in Scandia while Table 15 and 16 provide detail on specific impairments. Prepared by: Bolton & Menk, Inc.

Local Implementation Plan/Program Implementation of the Scandia Local Water Management Plan will require cooperation with local Watershed Districts to implement projects within the City that are identified in the District Plans. The City supports the projects identified in the District Plans and Capital Improvement Plans that are within Scandia, including the projects listed in Table 17. The CMSCWD plan describes three categories of activities that are included in the District's Implementation Program: routine watershed management, focused watershed management, and impaired watershed management. Most of the activities included in these efforts are implemented by the District. Some are implemented in cooperation with local landowners and volunteers. Cost -share Program, and identifies several existing or potential water quality and environmental issues that will be addressed by the program. The District has ranked the proposed projects on a watershed basis. Many of the projects will be carried out in cooperation with private landowners. The CLFLWD's Management Plan includes three categories of implementation activities: Administration, Programs and Projects. Administration activities are carried out by the CLFLWD. Programs include development of District rules and permitting activities, education and outreach. As noted above, the City concurs with and adopts the District's Prepared by: Bolton & Menk, Inc.

Assessing and Protecting the Water Source Scandia is part of the DNR's North and East Metro Groundwater Management Area, shown in Figure XX. A small segment of the city located south of Highway 97 and west of Manning Ave is also in the Drinking Water Supply Management Area for Minneapolis/St. Paul. The Minnesota Department of Health has identified a portion of the city for a Moderate to Highly Vulnerable Drinking Water Supply Management Plan; this area is located south of Highway 97, west of Olinda Trail, and east of Meadowbrook Avenue N. The city will work with the DNR, Department of Health, and other relevant agencies as necessary to ensure groundwater within these management areas is protected. There are two DNR observation wells located in Scandia, shown in Figure XX. Well 195728 is located near the eastern side of Big Marine Lake. This well is showing a downward trend in annual minimum values, meaning water is being used faster than it is being replenished. Well 244593 is located north of White Rock Lake. There is insufficient data at this well to determine a trend in annual minimum values. The city will also take special consideration of wetlands that receive and discharge groundwater or recharge aquifers to prevent potential contamination of groundwater drinking sources, shown in Figure XX.

The current plan was approved in 2014 and guides the protection of groundwater resources in the county until 2024. The overall goal of the Washington County Groundwater Plan is to protect the economic and environmental values groundwater provides through coordinated, intergovernmental efforts in research and assessment, policies, political influence, regulation, education, and consultation, and technical assistance. The plan has six main goals: • Concisely outline the physical nature of groundwater resources, discuss the issues that threaten groundwater, and provide direction and strategies on how to protect groundwater for future generations • Provide context and organization for stakeholders and residents to better understand the complex water governance structure • Serve as a framework to develop annual work plans for the county and its stakeholders that give specific implementation actions to address the groundwater issues in this plan • Compliment and coordinate with other state, regional, county, and local planning efforts • Guide collaboration on groundwater initiatives with state, regional, and local partners more efficiently and effectively • Be a resource for stakeholders and residents regarding groundwater information pertinent to the county.

Implementation Plan The Comprehensive plan creates a vision for the City of Scandia and guides land use and infrastructure improvements so that the City can meet the needs of the community in the future. The vision of the plan can only be realized if the plan is used. Tools to implement the plan will vary in that some will be reactive, such as zoning and subdivision ordinances that guide private developments, and others will be proactive, such as the City's Capital Improvement Program (CIP) for undertaking public improvement projects. 1. Official Controls To achieve the goals and objectives of this Comprehensive Plan, the City of Scandia has adopted a Development Code to establish regulations for zoning, subdivision of land, and shoreland and floodplain areas. The Development Code was originally adopted in November of 2010, with ongoing amendments as needed. Scandia's Development Code incorporates all land development regulations into a single code. Zoning City zoning codes regulate land use to promote the health, safety, order, convenience, and general welfare of all citizens. They regulate location, size, use and height of buildings, the arrangement of buildings on lots, and the density of population within the City. The City's zoning districts effectively guide development in Scandia. The City of Scandia is divided into eight zoning districts, detailed below and shown in Figure XX. There are permitted and accessory uses in most districts, as well as the other allowed uses under conditional use permit, interim use permits, or administrative permits. Table XX provides a high-level summary of each zoning district, and Table XX provides a summary of each overlay district; the full text of the current zoning ordinance is attached in Appendix XX.

Implementation Scandia 2040 Comprehensive Plan Update I N13112739 Page 9 Subdivision of Land The Subdivision Ordinance regulates the subdivision and platting of land within the City providing for the orderly, economic and safe development of land and facilitating the adequate provision for transportation, water, sewage, storm drainage, electric utilities, streets, parks and other public services and facilities essential to any development. City controls to regulate subdivision of land include an application process, legal notice and public hearings by the Planning Commission, and approval by the City Council. The process includes imposing applicable fees, a development agreement prescribing the standards for the development and imposing penalties for the violation of its provisions. The subdivision of land promotes the public health, safety and general welfare of the people and helps achieve the vision of this comprehensive plan by providing for standards in the development of land. The City also prohibits premature subdivisions. The Development Code defines a premature subdivision as any development inconsistent with the Comprehensive Plan, inconsistent with the City's CIP, inconsistent with environmental regulations, and lacking adequate infrastructure, including sewage treatment systems, streets and drainage. 2. CIP Capital improvement projects are major projects that benefit the City, including the construction or reconstruction of roads and sidewalks, sewer and water utilities, trails, and park and recreation facilities, as well the purchase of new or replacement equipment and buildings. A capital improvement program (CIP) is a budgeting plan which lists five years of needed capital improvements, their order of priority, and the means of financing. The City of Scandia's 2018-2022 CIP lists a wide variety of projects totaling more than $10 million. These projects are intended to meet the City's goals. The CIP is reviewed and updated annually by the City Council, to ensure the proper priorities and funding. The table summarizes the City's adopted 2018-2022 CIP. 3.

This timeline also incorporates programs and policies from the Housing Implementation Plan outlined in Chapter III. This timeline is subject to change due to unexpected natural and sociocultural events, shifting community needs, and political priorities at the County, State, and Federal levels. Amending the Plan To keep the Comprehensive Plan current, it will be necessary to make amendments from time to time. However, as the foundational document guiding development, most amendments should occur through a comprehensive effort to address changes to the community overtime. The Action Plan, described below, should be amended more frequently. Action Plan Worksheets Implementing the vision and goals of the Comprehensive Plan requires an action plan, and the coordination and investments of many stakeholders. The Action Plan worksheets in this chapter present a concise summary of the goals along with specific action steps, organized by chapter. The table includes: • Schedule: The schedule indicates when the action item might begin and is advisory in nature. • Lead: This represents the leader for the action item. The Lead will likely be a City staff person, but include coordination with other City departments, public, private, or non-profit entities. • Status: This section provides an update on the status of each action item. • Comments: This column is intended to allow further explanation of the action item. To ensure compliance with this 2040 Comprehensive Plan the following zoning ordinance changes will need to be implemented: • Update zoning map based on future land use plan • Reconcile inconsistencies between current zoning ordinance and intended future land uses Prepared by: Bolton & Menk, Inc.
