ITEM 3 West Sewer CapacityITEM 3 TPC3601 Thurston Avenue N, Suite 100 Anoka, MN 55303 Phone: 763.231 .5840 Facsimile: 763.427.0520 TPC(!-�)PlanningCo.com MEMORANDUM TO: Mayor and City Council FROM: Daniel Licht, AICP DATE: 14 March 2014 RE: Otsego — Comprehensive Plan; West Sewer District Capacity TPC FILE: 101.01 BACKGROUND The City adopted a Comprehensive Plan update in 1998 that coincided with construction of municipal sanitary sewer and water utilities. The 1998 Comprehensive Plan, as well as the most recent 2012 Otsego Comprehensive Plan update, establishes a policy that 30 percent of available waste water treatment capacity is to be reserved for commercial and industrial uses. The Comprehensive Plan also establishes that waste water treatment capacity is only reserved for subdivisions with approved final plats that have executed development agreements that include payment of sanitary sewer availability charges. With recent increased construction activity, City staff has had discussions with developers about preliminary and final plat applications for new residential subdivisions. Based on the development that occurred prior to the economic recession in the latter part of the last decade, the West Sewer District requires review to establish the amount of waste water treatment capacity that remains available for allocation. The City Council discussed this issue and directed City staff to prepare information to allow for interim use of the capacity reserved for commercial and industrial uses for residential subdivisions. Exhibits: A. Draft Resolution 2014 -XX B. Summary of West Sewer District Residential Developments C. Pages from 2012 Comprehensive Plan D. 2012 Comprehensive Plan Future Land Use Plan Map ANALYSIS W-WWTF Capacity. The West Waste Water Treatment Facility (W-WWTF) has permitted capacity of 600,000 gallons per day (gpd). Seventy percent of the W-WWTF capacity, or 420,000gpd, is available for residential development in accordance with the Comprehensive Plan. Based on a residential equivalent connection (REC) factor of 175gpd., the W-WWTF has capacity to serve 2,400 dwelling units. The allocation of capacity for commercial and industrial uses is 180,000gpd or 1,028RECs. Residential Development. To date, the City has approved final plats for 2,200 dwelling units within the West Sewer District. As of February 2014, 1,712 of the total dwelling units final platted (77.8 percent) have been constructed. There are 272 attached and detached townhouses final platted but not built within the West Sewer District, which is 12.4 percent of the final platted dwelling units. The rate of single family home construction has been increasing since 2010. City staff estimates that there are less than 250 vacant developed single family lots remain within West Sewer District and developers are proposing additional single family subdivisions in response. The City approved a preliminary plat for Martin Farms 2nd Addition consisting of 132 single family lots and for Zimmer Farms NW consisting of 58 single family lots. A replat of Pleasant Creek Farms 4t" Addition with a net decrease of 27 dwelling units has been also been preliminary platted. The initial developer of these lots has released their option on the property but there is interest from other developers in the project. After development of Martin Farms 2nd Addition, Zimmer Farms NW and the replat of Pleasant Creek Farms 4t" Addition, there would be capacity for 37 dwelling units unallocated within the limit on residential capacity established by the Comprehensive Plan. Within the West Sewer District north of 1-94, the Future Land Use Plan guides an additional 150 undeveloped acres for low density residential uses and 75 undeveloped acres of medium to high density residential uses. Assuming an average density of 3.0 dwelling unit / acre (du/ac.) for single family lots and 5.Odu/ac. for townhouses, we estimate a total of 820 dwelling units could be developed from the remaining undeveloped parcels within the West Sewer District. City staff has reviewed a sketch plan for the portion of Martin Farms west of MacIver Avenue that would result in development of approximately 140 single family lots. Commercial/Industrial Development. The 30 percent capacity reserved for commercial and industrial uses within the W-WWTF is equal to 180,000gpd or 1,028 RECs. ■ The City assumes as part of its utility facility planning that commercial and industrial uses will average 3.5 RECs per gross acre. The capacity of the 2 existing W-WWTF reserved for commercial and industrial uses is therefore estimated to support 294 acres of development. The 2012 Comprehensive Plan Future Land Use Plan guides 1,210 acres north of 1-94 within the West Sewer District for development of commercial, office and industrial uses. Total capacity needed to serve this area is estimated as 741,125gpd or 4,235 RECs or Only the existing developed uses in the Otsego I- 94 West Industrial Park and Kaleidoscope Charger School within these areas are connected to sanitary sewer. ■ An additional 308 acres south of 1-94 within the West Sewer District is guided by the Comprehensive Plan for development of commercial, office and industrial uses. Actual W-WWTF Usage. The Utilities Operations Supervisor has provided information that the average daily flow of wastewater to the W-WWTF was 286,OOOgpd or 48 percent of the permitted capacity of 600,OOOgpd. The Utilities Operations Supervisor and City Engineer estimate that up to 20 percent of the actual flow to the W-WWTF is inflow and infiltration of stormwater. As such, actual sewage flow to the W-WWTF is 228,800gpd or 38 percent of permitted capacity. Policy. The City has adequate sewer capacity within the West Sewer District based on established policies to continue build out of existing residential final plats and allow final platting of Martin Farms 2nd Addition, Zimmer Farms NW (to be known as Heritage Pointe) and the replat of Pleasant Creek Farms 4th Addition. There is no issue currently with available sewer capacity for commercial and industrial uses with only limited existing allocation from the available capacity reserved for these uses. Total build out of the West Sewer District north of 1-94 would require an additional 5,050 RECs or 883,750gpd. of capacity, which exceeds the planned Phase 2 expansion of the W- WWTF to 1.2 Million gpd. so it is necessary to consider the staged growth within the current west sewer district as well as possible future expansions beyond the current boundary. Development of additional residential subdivisions beyond these projects will require a policy decision related to the capacity reserved for commercial and industrial uses (absent initiation of plans to expand the W-WWTF). Even if all of the remaining residentially guided parcels within the West Sewer District were to develop, which is unlikely, City staff estimates there would still be available capacity for potential commercial or industrial development if such a project were to emerge. City staff therefore recommends a temporary suspension as to the limits on residential development exceeding 70 percent of the current permitted capacity of the W-WWTF. This action will maintain a supply of vacant developed lots to supply the continued increases in building activity with the City primarily occurring in the West Sewer District. This continued activity is important to the City in terms of revenue from utility availability and connection charges funding debt service for the construction of the sewer and water systems. A temporary suspension of the 70 percent policy limit will also allow the City Council sufficient time to consider the timing and process for expansion of the W- 3 WWTF, including an opportunity to receive additional evidence of a sustained economic recovery. CONCLUSION This item was discussed at the Administrative Subcommittee on 12 February 2014, which indicated its support for the proposed suspension of residential capacity limits within the West Sewer District. Prior to sending this issue to the Planning Commission for their input and recommendation, the Administrative Subcommittee requested that the full City Council consider the information prepared by City staff. The Adminstrative Subcommittee also requested that City staff provide an overview of the broader growth management policies adopted by the Comprehensive Plan. C.

Policy Plan Page 18 City of Otsego, Minnesota Comprehensive Plan Urban Service Area The urban service area, as graphically illustrated on the Growth Staging Map, is defined as the area of the City where sanitary sewer and water utilities are to be made available in accordance with the Urban Service Staging Plan and includes the following elements: Sewer Service District. The Sewer Service District identifies lands to which City sanitary sewer and water service is to be made immediately available and is comprised of two sub -districts. The immediate urban service area identifies lands that have received City entitlements to development, have made a financial commitment to obtain municipal utilities, and have been allocated sewer capacity. The intermediate urban service area identifies the remaining lands within the Sewer Service District that are eligible to access municipal utilities, but have not had development entitlements approved or provided the financial commitments to obtain sanitary sewer and water services. There are two designated Sewer Service Districts. The East Sewer Service District generally overlays that area adjacent to the TH 101 corridor and is served by a waste water treatment facility with a capacity of 1,000,000 gpd., collection system and potable water system. The City has also established a West Sewer Service District overlaying the area adjacent to Interstate 94 and surrounding the City of Albertville served by a second waste water treatment facility with a current capacity of 600,000 gpd., collection system and water facilities. The City will consider the expansion of the Sewer Service District boundaries only when: Land to be included in the sanitary sewer service district is not enrolled in an agricultural preservation program. 2. The land lies within one-quarter mile of the existing sanitary sewer service district boundary or presents environmental problems that can be alleviated by the delivery of City water and sewer service. 3. The land is located within the designated urban service expansion area and the expansion is in accordance with the order of the staging plan. 4. The potential sewer discharge of the land area to be included is within available capacity of the City's existing facilities. 5. The developer shall hold the City harmless should limitations on sewer hookups be imposed. Natural Environment Plan Page 63 rr. City of Otsego, Minnesota Comprehensive Plan 6. The developer and/or benefiting property owners assume the significant majority of improvement/service costs. 7. The land does not qualify as a premature development or subdivision as regulated by the Subdivision Ordinance. 8. Inclusion of the land in the sanitary sewer service district is necessary to achieve a five year supply and respond to a shortage of land to which service is available. 9. Commercial/industrial development and requests for service to existing, unsewered residential areas shall be given priority over new residential development for service district expansion requests. Urban Service Expansion Area. The urban service expansion area shown on the Urban Service Staging Plan defines areas of the City where the sanitary sewer and water utilities are to be expanded in the future. It is anticipated that as the sanitary sewer service district(s) reach near saturation, they will be expanded into the designated urban service expansion area. No timetable for expansion of the sanitary sewer service district is established or implied as part of the Comprehensive Plan. As a transitional district, densities of one dwelling unit per ten acres of land are to be allowed in the urban service expansion areas until these lands are brought into the sanitary sewer service district for development at urban densities in accordance with the Future Land Use Plan. The numerical designations of subdistricts within the urban service expansion area signifies the waste water treatment facility intended to provide service as well as the order these areas are to be served when capacity is available. The order for expanding the sanitary sewer service districts is based on minimizing infrastructure investments and maintenance of concentrated service areas. Long Range Urban Service Area. The long range urban service area is designated for that portion of the community where one plus acre unsewered single family residential development has occurred. The extension of municipal sewer and water service to this area is not anticipated until it may be mandated by pollution concerns or specifically requested by property owners (via petition). Further unsewered development in the area is not recommended and residential development density is limited to one dwelling unit per 40 acres unless the City Council finds that one or more of the following criteria are met: The development will result in completion of an unfinished street network.
