Meeting Date and Time: February 15, 2022 at 2:00 p.m. Applicant: Elkhorn Ridge Development Request: Approve an update to the Elkhorn Ridge DRD Concept Plan and change zoning from Ag to DRD (Development Review District) on a 14+/- acre parcel located approximately 1500 feet west of Colorado Loop. Action: Set a public hearing for March 1, 2022 Location: Parcel to be zoned from Ag to DRD, Elkhorn Ridge Master Plan Boundary Proposal Summary: This will update the DRD concept plan to reflect past final plan approvals, add more definition to areas previously identified as “future” development, refine land use for undeveloped parcels, and bring a 14 acre parcel into the official Elkhorn Ridge DRD concept plan. Page 1 Spearfish Planning Commission Staff Report Meeting Date: February 15, 2022 BACKGROUND AND HISTORY: • Annexed and rezoned in the early 2000’s to Development Review District • The original DRD concept plan was updated in 2007 which is attached to the staff report. • Since the 2007 update, the following final plan approvals have been made: o Golf course, clubhouse, maintenance building and the Miller Creek Pub o Preliminary plats for residential north of I-90 o Travel center gas station, convenience market, and restaurant o Elkhorn Ridge Development office building o Peaceful Pines Senior Living facility and duplex residential o Storage buildings west of Miller Creek • Surrounding zoning and development patterns: o Overall, the master plan is bounded on the North, East and South by County AG- 1 zoning, one lot per 40 acres. o Southwest is the Sky Ridge affordable housing project also zoned DRD, Development Review District o West is the Centennial Mountain Estates property, undeveloped at present, but proposed to be a mixed use multi-phase development. • Site data: o Original Elkhorn Ridge Master Plan – 910 +/- acres o Parcel to be rezoned from Ag to DRD west of travel center: 14 +/- acres o The 14 acre parcel will bring the total master plan acreage to 924 acres o 10 percent open space requirement ▪ 92.4 acres required / provided open space is 362 acres. REVIEW CRITERIA AND STAFF ANALYSIS: The Elkhorn Ridge DRD approval is a two-step DRD plan, meaning, the land uses are identified on the concept plan and a final plan approval is submitted for a later approval and shows specific detail for site layout, building design, and landscape. This DRD concept plan update captures the existing approvals noted above as well as the following to these undeveloped parcels: 1) North end of the Exit 17 interchange - from Future Development to Single Family and Multi Family residential, and Health Care. 2) Southwest corner of Interstate 90 and Highway 85 – from Retail to Commercial. The allowed uses as commercial in the DRD are generally those from the C-2 zoning list except for the list of land uses that are prohibited in the DRD. 3) West of St. Onge Road, and south of Acorn Ridge Road, from Mixed Use Office/Retail/Residential to Single Family and a 5 acre portion along Acorn Ridge Road as Multi Family. 4) Southwest corner of Highway 85/St. Onge Road from Office Park to Health Care (Monument Health 70 acre parcel). 5) Rezones the 14 acre parcel west of the travel center from Agriculture to Commercial. 6) Sky Ridge is shown for context on the revised master plan attached to the staff report, however it is governed by a separate approval made in 2020. Page 2 Spearfish Planning Commission Staff Report Meeting Date: February 15, 2022 The change of zoning for the 14 acre parcel from Ag to DRD-Commercial is guided by the City of Spearfish Revised Code of Ordinances, Article IV., Section 10. Development Review District Section F.2 a-g. Staff’s analysis follows each statement in italic text. Concept Plan Approval Criteria. In consideration of a request for Concept Plan approval, the Planning Commission and City Council shall take into account factors including, but not limited to: a. Conformance with the goals and policies of the comprehensive plan; The change of zoning for this parcel to DRD-Commercial is a logical extension of the existing commercial zoning to the west and because the property fronts both Colorado Boulevard and Interstate 90, it has prime exposure for additional sales tax generating land uses. b. Compatibility with and relationship to existing and potential uses adjacent to the proposed project; See above. c. Public safety issues relating to projected traffic generated by the proposed uses and to the existing or potential transportation system of adjoining properties; Colorado Boulevard is slated to be widened in the next 5 years across this parcel frontage, which will add left turn capacity for east bound drivers entering the site. d. Community benefit of the proposed use(s); Sales tax generating land uses are important to the overall economic health of the community and with the presence of the Sky Ridge and Elkhorn Ridge neighborhoods nearby, a location for every-day goods and services is available within walking distance. e. Aesthetic considerations related to the scope and size of (the) proposed use(s); The final plan submittal in the 2nd step of approval will address this issue. f. Adequacy of public services for the proposed use(s); Within the next 2 years, the upgrade to the Elkhorn Ridge sewer lift station should be complete and adequate capacity will be available for this commercial development’s sewer flow. g. Testimony received from the public at the public hearing. None received as of this writing. PUBLIC COMMENTS: Notice of a public hearing will be published in the newspaper and sent to owners within 140 feet of the property boundary. The Lawrence County Planning and Zoning director and County Highway Superintendent will be notified of this request. Also, this request will be advertised in STAFF RECOMMENDATION: Set a public hearing for March 1, 2022 ATTACHMENTS: Page 4 - Aerial Map Page 5 – 2007 Concept Plan Page 6 – 2022 Updated Concept Plan Staff Contact: Jayna Watson, City Planner, 605-717-1122; jayna.watson@cityofspearfish.com Join by zoom teleconference: https://us02web.zoom.us/j/88035937353 Meeting ID: 880 3593 7353 Page 3 Spearfish Planning Commission Staff Report Meeting Date: February 15, 2022 Or Dial In: 1 253 215 8782 and enter Meeting ID Yellow=Elkhorn Ridge Master Plan – Concept Plan Boundary Blue = Parcel to be zoned from AG to Development Review District.

Staff will be introducing this document at the above meeting and its purpose is to serve as a decision making policy for future requests for development approval in the east Colorado Boulevard corridor. The primary topics covered in this study are recommendations for: • Land use and preferred locations for more intense land development within the context of a City Services Boundary, and what areas are likely to remain more rural • Water/sewer infrastructure requirements based on recent city investment to upgrade the Elkhorn Ridge lift station • Colorado Boulevard upgrade to create a more efficient, safe roadway No action is requested on February 15, however discussion and input is requested so that action may be taken at the next meeting on March 1. Early March – City and County Planning Commission review and recommendation Mid-March – City and County governing body adoption of the study Note that the terms used in this document are suggestions for what should happen in the future growth of this area and are not mandates. Some of the recommendations of the plan require a follow up effort to adopt a resolution or ordinance to fully implement the concept discussed in the report.  East Colorado Boulevard Corridor Study A Planning Partnership With: Adopted by the Adopted by the City of Spearfish City Council on: Lawrence County Commission on: East Colorado Boulevard Corridor Study Study Committee: Larry Klarenbeek, Spearfish City Councilman Meghan Byrum, Spearfish Planning Commission Member Richard Sleep, Lawrence County Commissioner Rick Tysdal, Lawrence County Planning and Zoning Commission Member Bruce Outka, Lawrence County Deputy States Attorney Amber Vogt, Lawrence County Director of Planning and Zoning Ashley McDonald, Interim Spearfish City Administrator and City Attorney Jayna Watson, Spearfish City Planner Stacy Bartlett, South Dakota Department of Transportation Access Management Engineer Mike Carlson, South Dakota Department of Transportation Rapid City Area Engineer Joe Jorgensen, Property Owner in the study area Introduction and Purpose Ongoing development at Elkhorn Ridge and the recent development of the Sky Ridge neighborhood and sports complex have resulted in an increase in development interest for the Colorado Boulevard corridor between Maitland Road and Highway 85. The purpose of this document is to provide policy guidance as requests for changes in land use are made to either the City of Spearfish or to Lawrence County. This Study Will Make Recommendations For: a) A mix of development types within the context of public utility service, present and future street network, and trends in residential, commercial, and industrial land uses. b) Preferred locations for urban/suburban and rural/low intensity land uses. This Study Will Not: a) Change the existing zoning or land use rights of any individual property. b) Replace the traditional process whereby changes in zoning are requested or initiated. Using historic growth and development trends, the following is a projection of the number of dwellings and commercial square footage that could be expected within a ten-year planning horizon within the study area. This timeline has been chosen because it represents the most accurate forecasting based on recent growth and development trends. Estimates for development past 2032 are difficult to quantify due to the number of economic variables involved. For this reason, there must be realistic expectations so that resources can be directed toward the critical infrastructure both within the Colorado Boulevard corridor as well as the primary gravity sewer infrastructure west of the study area and the wastewater treatment plant. 2-15-22 Draft East Colorado Boulevard Area Study | 2 The following are the ten-year growth assumptions for the study area, using a straight-line projection based on Census data: a. Spearfish growth rate = 16% (from 2010 to 2020)* b. Current Spearfish population = 12,193* c. New projected residents 2020-2030 = 1,950 d. People per household = 2.12* e. New homes 2020-2030 = 300 (assumes 1/3 of all new homes built in the next ten years will be in the study area) f. New non-residential land use estimate: 72,000 square feet - retail, food service, light industrial * 2020 Census Data Study Area The study geography includes the area between Maitland Road and Highway 85 and 3/4 mile north of Interstate 90 and south to Centennial Road as illustrated by the map below. Within this overall boundary lie undeveloped and sparsely developed areas that are likely to change land use in the future, depending primarily on the availability of water and sewer infrastructure and land use compatibility. Areas within the study area where development has taken place (Sky Ridge, Elkhorn Ridge) require no re-evaluation for future land use but are included in the area study for context. Pink = City Limits Blue Line = Study area geography Rainbow Rd. Colorado Blvd. Maitland Rd. Centennial Rd. 2-15-22 Draft East Colorado Boulevard Area Study | 3 Most of the study area is rolling terrain with slopes generally 2% to 10% with locally steeper areas in drainageways and at the hillside landform north of Exit 17. Floodplain is limited to Miller Creek toward the east edge of the study area. The primary vegetative cover is prairie grass with stands of trees along drainageways and shelter belts. Maitland Road is the highest point at the west edge of the study area and all drainage at this point flows west toward Spearfish. Two localized drainage low points exist: Miller Creek and at Rainbow Road extending east and west for ¼ and ½ mile respectively. This topography plays a major role in how the area is provided with gravity sewer. Existing Conditions Land Use and Zoning Beginning at the intersection of Maitland Road and Colorado and moving eastward, the following are existing land uses and zoning districts. Except for the Maitland Road Area, the corridor is mostly undeveloped, open land until the west boundary of the Sky Ridge subdivision. City Limits - C-2 Highway Service Commercial for ¼ mile east of Maitland Road; storage buildings, retail and repair businesses, equipment, and automotive dealerships. Unincorporated County – HSC Highway Service Commercial and Ag-1; office, residences, barns. City and County Ag zoning – homes and barns in the Rainbow Road vicinity and east to the west edge of the Sky Ridge neighborhood. City Ag zoning north of Interstate 90 and east of Rainbow Road – Ag zoning with recent preliminary plat approval for a new 54 lot subdivision consisting of one acre lots known as Centennial Mountain Estates. City Development Review District Zoning – Sky Ridge single family residential neighborhood soccer and softball sports complex, storage buildings, and Elkhorn Ridge travel center (convenience market and gas station). An avigation easement related to the Spearfish Airport exists in the Colorado Boulevard and Rainbow Road vicinity. This easement limits building heights based on the applicable conical surface of the easement and the specific ground elevation for where a building is to be constructed. Determination of allowable building height requires an assessment performed by a registered land surveyor. 2-15-22 Draft East Colorado Boulevard Area Study | 4  Elkhorn Ridge Residential and Golf Course Centennial Mountain Estates Maitland Rd. Colorado Blvd. Sky Ridge Elkhorn Ridge RV Resort Centennial Road Zoning Map County Zoning Red Cross Hatched – Ag-1 Yellow – Highway Service Commercial City Zoning Green – Agriculture Gray – Development Review District Red – C-2 Highway Service Commercial Public Utilities In 2003, the City of Spearfish partnered with the developer of Elkhorn Ridge to pay for the extension of water and sewer infrastructure to serve the needs of that mixed use residential, commercial, and healthcare development. A 12 inch water main exists on the south side of Colorado Boulevard and provides adequate pressure and flow to support the ongoing growth of the area. The source of the water is the 2-15-22 Draft East Colorado Boulevard Area Study | 5 Green Acres tank, owned and operated by the City of Spearfish, and located approximately two miles southwest of Maitland Road. All of Elkhorn Ridge and Sky Ridge sewer flow is conveyed by gravity sewer to a city owned and operated lift station just west of Miller Creek. From here, the flow is pumped uphill in two six-inch force mains west to Maitland Road where it then returns to a gravity flow condition. Electric, natural gas, and communications serve the area. Colorado Boulevard Serving as a major east/west arterial street parallel to I-90, this is a two lane highway with minimal roadside shoulders. The posted speed limit is 55 mph but changes to 45 mph west of Maitland Road. With the Sky Ridge development, a traffic study was completed and it recommended the widening of the highway along the project frontage to construct left-turn lanes into Sky Ridge. Due to the future westbound volumes modeled in the study, a left turn lane at Rainbow Road to facilitate access to northbound Rainbow Road was also recommended. The turning lanes for Sky Ridge are slated for construction within the next 5 years by the City of Spearfish. It is undetermined when the left turn lane at Rainbow Road will be constructed. No on-street bicycle lanes exist on Colorado and the city’s trail and path network has yet to reach this area of the community. Land Use Recommendations The primary consideration for if land in the Colorado corridor is developed as low intensity rural uses or city residential and commercial uses depends on the availability of water and sewer infrastructure. The City of Spearfish has designated the areas immediately south of Colorado Boulevard as the preferred location for where annexation and intensification of land use should occur because of the public services available. In late 2021, the City of Spearfish committed to add capacity to the Elkhorn Ridge lift station upgrade, thus securing future sewer services for the growth of this area. The land use recommendations are divided into what is a preferred scenario for property annexed to the city for more intense land use, and property that will remain more rural in character according to county zoning. The division between these city/county land uses is the City Services Boundary (see map on page 9 for location). Areas north of the boundary represents the best opportunity for cohesive and well-connected land use and infrastructure. Unless it is part of a plan of development within the boundary, property outside of the boundary should be reviewed for if it: 1) can be reasonably and feasibly served by all city services, 2) initiates a pattern of development in a direction inconsistent with the vision of infill growth of this area. Land Use– Annexations to City of Spearfish and Changes of Zoning The following are key strategies for areas within the City Services Boundary where annexation and change of zoning is requested. The overall goal for this land area is to maximize the development opportunities versus the preservation of rural/ag lands. 1. A mix of land uses are envisioned to include a range of residential densities, commercial, and light industrial uses. 2. Residential densities and lot sizes that support affordable housing and are encouraged. 2-15-22 Draft East Colorado Boulevard Area Study | 6  3. The timing of annexation/rezoning requests should be when the owner has a specific plan of development that will enable the city to understand the benefits of the project as well as the impacts of the project on city infrastructure. 4. Where more intense land uses are abutting/adjoining land uses of lesser intensity, an appropriate transition to achieve land use compatibility should be provided. Examples: a. Larger lot sizes at the perimeter of an area unlikely to be developed at an urban/suburban density. b. Increased setbacks above ordinance requirements, vegetational buffers, fences, berms. c. Commercial development along Colorado Boulevard should occur in clusters where there is the ability to share access and for efficient traffic control. Visual quality is an important factor in growth management. The following are strategies to guide and direct this aspect of community development, and it is primarily related to multi-family and commercial/industrial structures: 1. Architectural creativity in non-residential structures should include variations in overall design style, roof forms, exterior finishes, and building color. 2. To create a unified and finished look, site frontages should be landscaped and include a variety of trees and shrubs with an overall preference for drought resistant types. 3. The outdoor display of equipment and vehicles should be provided within a setting that incorporates plant material, changes in landform, boulders, decorative walls/fences, and similar landscape architectural features that complement the display. 4. All outdoor lighting and illuminated signage should meet the criteria as established by the International Dark Sky Association, www.ida.org Land Use – Development under Lawrence County zoning authority 1. For areas outside of the City Services Boundary, Rural Residential, Park Forest and A-2 Residential Agriculture zoning districts should serve as a land use buffer between the more urban forms of development within city limits and the lower density A-1 General Agriculture district. 2. City of Spearfish will review and provide comment on conditional use permit requests within the study boundary. 3. Requests for development approval involving mixed land uses and/or development intensity greater than what the Rural Residential zoning allows are encouraged to be submitted as Planned Unit Development. Spearfish Airport Land Use Compatibility The approach to the Spearfish Airport is immediately northwest of the Rainbow Road and Interstate 90. Land uses in this vicinity should be evaluated for future compatibility with air traffic with commercial land uses being preferred over residential land uses. 2-15-22 Draft East Colorado Boulevard Area Study | 7 Water / Sewer Infrastructure Recommendations Water The present water delivery system can support growth and development for the next several years and a new well and water storage reservoir is included in the City’s capital improvement program to be designed within the next two years. This will be the primary water supply to the area with additional support from the system feeding from the Green Acres tank. The following are key criteria to guide decisions involving water services in addition to standard city ordinances. 1. Where technically necessary, new water mains should be looped to connect to existing water mains to increase pressure and flow. If no point of connection exists, mains should be stubbed out for future connection. 2. Requests to provide water service outside of city limits should consider the number of users served, the potential for expansion of the system beyond the property requesting service, and the cost/benefit of the service. 3. The city may elect to pay for the upsizing of water mains to serve future development. Sewer A key consideration for future growth is the capacity of the Elkhorn Ridge sewer lift station and force main system. An upgrade to this system will take place during 2022-2023 to add more sewer capacity to the area since the current system is nearing capacity now. The city’s costs for this added capacity will enable up to 854 gallons per minute (GPM) of sewer flow from the presently undeveloped area within the City Services Boundary. Of this total, 419 GPM is allocated to the areas south of Colorado Boulevard and the remainder is allocated to the Centennial Mountain Estates development. The following are the key considerations to guide the development of the gravity sewer infrastructure expansion that will link to the newly upgraded lift station: 1. The costs of gravity sewer infrastructure connecting to the Elkhorn Ridge lift station are the responsibility of the property developer and should be constructed at the time the property is developed with structures or other infrastructure that will be municipally owned. 2. A one-time charge based on sewer flows directed to the lift station should be implemented at the time of annexation and simultaneous change of zoning to reimburse the city investment for the lift station upgrade. 3. Once allocated and paid for, sewer capacity should be permitted to be traded or sold between private parties, and the city should develop a method to track these exchanges. 4. A special tap fee should be considered by City Council for users connecting to the Elkhorn Ridge lift station. This special rate is justified by the additional resources and costs required in lift station operation that gravity sewer does not require. 5. Gravity flow is possible for the following locations and could support land use patterns that are more urban/suburban in character: a. East side of, and immediately adjacent to Maitland Road, and south of Colorado Boulevard. b. ¼ mile east of Rainbow Road to the west boundary of the Sky Ridge neighborhood. c. Portions of the Centennial Mountain Estates property north of I-90 and east of Rainbow Road. 2-15-22 Draft East Colorado Boulevard Area Study | 8  6. Areas where gravity flow is not possible is from a point roughly 600 feet east of Maitland Road to ¼ mile east of Rainbow Road and roughly ¼ mile north of I-90 east of Rainbow road. These areas are more likely to be more rural in character for the near term unless alternate methods for wastewater treatment are provided. 7. Requests to provide sewer service outside of city limits should consider the number of users served, the potential for expansion of the system beyond the property requesting service, and the cost/benefit of the service. 8. The city may elect to pay for the upsizing of sewer mains to serve future development.

For property fronting Colorado Boulevard, the following should be evaluated at the time of a request for annexation/change of zoning to City of Spearfish, or at the time of a request for preliminary plat approval for parcels that are not annexed but within the 3-mile extra territory for subdivision approval. 1. A traffic study should be provided according to the criteria of the MTP VI.B of the plan, and for projects generating 100 trips at the morning or evening peak hour. The purpose of the traffic study is to determine: a. Levels of service for new streets connecting into Colorado Boulevard, and the appropriate traffic control methods. b. Spacing of intersections and driveway access points. c. Need for dedicated left and right turning lanes. d. Potential for widening of Colorado Boulevard. 2. Right-of-way for Colorado Boulevard should be dedicated at the time of final plat approval. 3. Collector level streets shown on the Major Streets Plan of the MTP should be incorporated into property development plans The City of Spearfish has tentative plans to widen Colorado Boulevard within the next 5 years along the Sky Ridge frontage. Although design has not started, a possible cross section for a two lane arterial per the MTP in Section VI.C, Figure 16 of the plan, is shown below. In addition to city funding sources and grants, property owners should also participate in costs of the upgrade if their development approval results in new traffic added to the roadway. The following are potential options to be explored: 2-15-22 Draft East Colorado Boulevard Area Study | 10  a. Cost sharing agreements created at the time of development approval, based on a proportional amount of new traffic generated by the individual development compared to the overall volume on Colorado Boulevard. b. Recovery of costs through special assessments and based on a proportional amount of new traffic generated by the individual development compared to the overall volume on Colorado Boulevard. Paths/Trails The MTP Illustrates a multi-use path along the Colorado Boulevard corridor and along Maitland Road, as shown on the next page. This path will provide an important link for pedestrians and recreational bike travel from the study area to the remaining portions of the Spearfish recreational path system. The City of Spearfish should conduct a feasibility analysis to determine the best location for the path prior to incorporating recommendations for specific development proposals. Green dotted line = recommended location of multi-use path/trail per the MTP. Conclusion and Summary The area within the study area is envisioned to develop with a mix of land uses where public infrastructure is available to serve it. Where public infrastructure is not available, options for rural development and agricultural preservation remain. Orderly growth and development depend upon clear criteria to guide and direct this growth. The recommendations of this plan serve as a guide so that decision making is based on an informed set of parameters, rather than on an ad-hoc basis and without an overall vision. 2-15-22 Draft East Colorado Boulevard Area Study | 11
