Plat approval for Hunters Pass Estates was originally attained by the Minnesota Development Agency, LLC in 2005. Approval of the plat has since expired and Tollberg Homes is proposing some updates to the original plat, so that additional review and approval by the City is required. The entire Hunters Pass Estates development consists of 96 single family lots on 76.6 acres of land in the northeast corner of Albertville. Sixty-three single family lots were developed in Phase I of the development, and Tollberg Homes is now proposing to develop an additional 12 lots. The site is located to the west of Phase I of Hunters Pass Estates, and is bounded on the north by 70t" Street, on the south by Hunters Lake and on the west by the Towne Lakes development. The site is zoned R-1A (PUD), and is located within the Shoreland overlay District of Hunters Lake. The Hunters Pass Estates subdivision is based on a concept known as "coving." Coved subdivisions utilize curvilinear street patterns and varied front yard setbacks as a means of providing more visual open space and unique streetscape appearance. Protection of wetland areas associated with Hunters Lake is also a priority for the subdivision, and impacts how the development approaches side and rear setback, lot area, lot width, street right-of-way width, and street width requirements. To facilitate the coved design, the subdivision received City approval of a PUD to grant flexibility in lot area, width and setbacks. Attached for reference: Exhibit A: Preliminary Plat Modification Exhibit B: Phasing Plan Exhibit C: Site Location Map Exhibit D: Development Plan Exhibit E: Final Plat Exhibit F: Setback Worksheet 0 ISSUES ANALYSIS Existing Conditions. The site is located in the northwest corner of Albertville. Hunters Lake isolated this site from the remainder of the City. Phase I of the Hunters Pass Estates development has already been completed, including construction of the internal road system. The current proposal for Phase II of development is implementing what was approved with the original plat, with small revisions as described further on in the report. Hunters Pass Estates Phase II consists of 21 acres of land, including significant wetland areas. The western portion of the site, adjacent to Towne Lakes 6t" Addition, will be developed at a later date. Comprehensive Plan. The Comprehensive Plan designates the site for Low Density Residential Development, of which the proposed development is consistent. The applicant is proposing a single family subdivision utilizing a "coving" design that integrates with the site's natural features. The design will require flexibility from the R-1 A District lot area, lot width, and setback standards. The Planning Commission and City Council must make a determination as to whether the amenities received in doing a development of this design warrant the requested PUD flexibilities. Shoreland Regulations. With approval of the Hunters Pass Estates subdivision in 2005, the City also granted approval of a requested Conditional Use Permit Planned Unit Development for the site. The City chose to pursue the shoreland provision for planned unit developments (Section 4908.75) and processed the application as a standard PUD/CUP. This allowed for flexibility in lot width, lot sizes, setbacks, etc., subject to the following site and design criteria: (Section 4908.75) A. Minimum project areas shall be as follows: Residential: Ten (10) acres B. The total density of the site shall not exceed that which is permitted by the underlying zoning. C. Individual lot coverage by impervious surfaces shall not exceed thirty percent (30%). D. At least fifty percent (50%) of the project area shall be preserved as open space, public or private. open space shall meet all the requirements of section 4908.62 of this chapter and shall not include roads, sidewalks, parking areas or building footprint areas. At least one-half (1/2)of the preserved open space required by this chapter must be in tier 1 of the shoreland area defined in section 4908.41 of this chapter. E. Density may be transferred among the tiers and/or structure and parking setbacks may be reduced to a minimum of seventy five feet (75') from the ordinary high water level; provided, that all of the following mitigating measures are completed: 1. A natural undisturbed vegetative buffer at least thirty feet (30') in width is maintained adjacent to the wetland/water's edge of OHW, whichever extends further landward. I 2. A planting plan be designed and implemented that enhances or restores the natural buffer with a combination of grasses, shrubs, and trees appropriate to complement the natural habitat. 3. Permanent markers shall be installed and maintained indicating the buffer edge along the entire shoreland boundary. 4. A homeowners association document shall be created and recorded that includes provisions for maintenance of the shoreland markers, prohibits the use of fertilizers containing phosphorous in rear yards, and that provides a mandatory penalty for violations of the homeowners' association and provisions of this chapter. Promect Area and open Space Coverage. The 2nd Addition project area is 2 1 acres total, and will consist of 12 single family lots, outlot A, and outlot B. Though only a portion of that area is currently proposed for development, the proposed subdivision in its entirety appears to meet the minimum project area requirement of 10 acres. Wetlands and buffers are open space, protected as outlots and easements over the entire plat. More than 50% of the entire plat (including the 1st 7 2"d, and 3rd Additions) will be preserved as permanent open space. The individual lot coverage by impervious surface requirement shall be met upon completion of construction of homes on lots. Wetland Buffer. How the project addresses the required wetland buffer has changed from Phase I of development. The City Engineer is recommending that lots in Blocks 2 and 3 of Hunters Pass Estates Phase II be reduced in size from that approved with the original plat, to allow space for the required wetland buffer area to be external to lots and within outlot A. The goal here is to increase the likelihood of the buffer being protected and maintained over time. Lots in Hunters Pass Estates Phase I contain an easement for wetland buffer areas interior to lots. However the City has experienced difficulty in enforcing the protection of these buffer areas, due to the fact that the location within lots is difficult to determine over time as locational signs are removed, and the buffer itself is mowed by residents who do not wish to maintain it. The designation of the required wetland buffer area to outlot A in the current proposal means that mowing or removal of the buffer becomes a trespass issue, which is more enforceable by the City. The applicant is requesting that the City permit reduced lot size, reduced rear setbacks, and small adjustments to house pad locations from that approved with the original plat in order to implement the wetland buffer in outlot A. Exhibit A "Preliminary Plat Modification" demonstrates lot areas approved in the original plat, in addition to reduced lot areas currently being proposed. In addition, Exhibit F details front, side and rear setbacks for Phase II lots. Zoning. The site is zoned R-1A (PUD), and is located within the Shoreland overlay District of Hunters Lake. Hunters Lake is designated as a Natural Environment Lake. The following setback and lot standards are applicable to developments within the R1-A, PUD and Shoreland Management overlay District: 10 R-1A District Requirement Proposed Minimum Lot Area 15,000 square feet 87220 — 147510 square feet Avg. 10,725 square feet Minimum Lot Width (Interior) 100 feet 51 - 93 feet Minimum Lot Width (Corner) 120 feet NIA Front Setback 30 feet 30 - 58 feet Side (Interior) Setback 10 feet 10 — 23 feet (house side) 5 feet (garage side) ** Side (Corner) Setback 30 feet NIA Rear Principal Setback 25 feet 20 feet minimum ** Rear Accessory Setback 10 feet Shall meet requirement Maximum Building Height 35 feet Shall meet requirement Maximum Building Lot Coverage 25% Shall meet requirement Maximum Units per Acre 2.9 units per acre 4.1 units per acre 5horeland overlay District (PUD) Structure Setback from OHWL 75 feet Min. 80 feet Lot Coverage by Impervious Surface Maximum 30% Shall meet requirement Project Area open Space Coverage Minimum 50% Shall meet requirement Wetland Buffer 30 feet Shall meet requirement *As measured from the adjusted front yard setback **Planned unit developments as outlined in subsection 4908.78E, may have reduced structure setbacks when mitigating measures are completed. Hunters Pass Estates PUD approval allowed for reduced side, front and rear setbacks, as described in the report. Plat and PUD approval of the Hunters Pass Estates subdivision in 2005 allowed for reduced lot areas and setbacks to allow for implementation of the coved subdivision design and increased protection of wetland areas. Approval at that time permitted side yard setbacks of 5 feet on the garage side and 10 feet on the living space side (interior lots), 30 foot side yard setbacks on corners, front yard setbacks of ± 30 feet (resulting in a lot width of 80 feet at the front building line), and rear setbacks of a minimum of 30 feet. As demonstrated in Exhibit F, setbacks for Hunters Pass Estates Phase II lots coincide with setbacks approved in the original plat, with the exception of rear setbacks. Upon recommendation from the City Engineer, lots in Block 2 and 3 have been reduced in size to provide for a wetland buffer area exterior to subdivided parcels. This reduction in lot area is tied to a reduction in rear setbacks by 20 feet on impacted lots (given similar location of the building pad and application of all other setbacks), resulting in rear setbacks as small as 10 feet. Lot Design. Low Floor Elevation. Low floor elevations for parcels on lakes must be a minimum of three feet above the Ordinary High Water Level (OHWL). The OHWL for Hunters Lake is 947.3, in which case the minimum low floor elevation is 950.3 feet. All building pads in the proposed development maintain the described minimum floor elevation. 11 Steep Slopes. The site contains areas of steep slopes exceeding a 12% grade, particularly in lots abutting Hunters Lake. The City Engineer must evaluate possible soil erosion impacts and development visibility from public waters before issuing a permit for construction of roads, driveways, structures, or their improvements on steep slopes. When determined necessary, conditions must be attached to issued permits to prevent erosion and to preserve existing vegetation screening of structures, vehicles, and other facilities as viewed from the surface of public waters, assuming summer, leaf -on vegetation. The applicant must adhere to any recommendations the City Engineer makes in these regards. Circulation/Access/Street Design. The applicant is proposing to extend 69t" Street Circle NE from the existing Hunters Pass Estates subdivision into the proposed subdivision expansion. The street will culminate in a cul-de-sac. No additional access to 70t" Street is proposed, but residents will gain access via LaSalle Circle, which connects with both 69t" Street Circle and 70t" Street. The applicant is proposing to construct the 69t" Street Circle extension to match right-of-way width and curb -to -curb width as previously approved for the street in Phase I of development (50 feet right of way, and 28 feet curb to curb). The final street design is subject to the review and approval of the City Engineer. Grading and Drainage. The applicant has submitted grading, drainage, and utility plans which are subject to the review and approval of the City Engineer. Wetland Mitigation. The applicant has delineated the wetlands on the site. Proposed lots are located outside of the existing wetland boundary, and wetland areas have been designated as outlot A, which will be maintained as a permanent drainage and utility easement. Landscaping. The applicant has not provided a landscaping plan. The Zoning ordinance requires that one shade or evergreen tree be planted per residential lot, which will be required as part of the development agreement. Additionally, all lots backing onto 70t" Street must contain a minimum 20 foot in depth vegetative buffer consisting of staggered plantings that meet the City's screening requirements. This is of particular importance given the expectation of the City that traffic volumes on this road will continue to increase in the future. The applicant shall submit a landscape plan indicating the location of the described buffer planting. The planting plan for Phase II should otherwise adhere to the landscape plan submitted and approved with the final plat for the Hunters Pass Estates PUD in 2005. Park Dedication. According to ordinance Section 1 1 -7-8-2 of the City Code, the applicant is required to dedicate to the City for park, playground, and public open space purposes a minimum amount of land or cash, or a combination of the two. Phase I park land dedication was accomplished lished with the creation of a park on the north portion of Hunters Pass Estates, just south of 70 Street. A cash dedication of $3,300 per single family lot will be required for Phase II of development. The required dedication shall be made prior to the City's release of the final plat for filing. Homeowners Association. All property owners in the Hunters Pass Estates 1st Addition are part of the Hunters Pass Estates Homeowners Association (HOA). The HOA adopted a set of architectural guidelines to guide Phase 1 lot and subdivision design. Phase II of development must follow architectural guidelines provided in Phase I of development, and all Hunters Pass Estates 2nd Addition homeowners must join and adhere to standards provided by the Hunters Pass Estates HOA. 12 RECOMMENDATION Upon review of the proposed Preliminary and Final Plat for Hunters Pass Estates 2nd Addition, it is staffs' view that the proposed 12 single family lots are consistent with the intent of the Comprehensive Plan for the subject area. The Planning Commission and the City Council must determine if the requested flexibilities are acceptable. Staff recommends approval of the proposed plats subject to the following conditions: The grading and drainage plan is subject to the review and approval of the City Engineer. 2. The applicant shall install and maintain wetland demarcation signage at the boundaries of the wetland buffer. 3. The applicant shall provide a landscape plan illustrating a vegetative buffer planting along the northern border of the site, between Phase 11 lots and 70t" Street. In addition, one shade or evergreen tree must be planted per residential lot, which will be required as part of the development agreement. All other plantings shall adhere to the landscape plan approved with the final plat for the Hunters Pass Estates PUD in 2005. 4. Provide a park dedication fee totaling $3,300 per individual lot, to be paid prior to the release of the final plat for filing. 5. The applicant shall address any additional comments from City Staff. 6. The applicant shall adhere to established architectural standards (design guidelines) for the Hunters Pass subdivision, as adopted by the Hunters Pass Estates Homeowners Association. 7. The applicant shall comply with the recommendations of the Fire Inspector. 8. The final plat shall be brought into the Hunters Pass Estates HoA, and the developer and Phase II homeowners shall adhere to the HoA declaration, bylaws, and rules, and any addendums to said standards. c: Sue Schwalbe Kim Olson Paul Heins Mike Couri Nathan Jones, Tollberg Homes, 1428 5th Avenue, Anoka, MN 55303 13 EXHIBIT A T W WAPM MALE I' Vn'A7Rb{yy��lf8kllyaurrysuslylrNlrffil8�'MisriliBll Jle 142S Sth Avenue Anoka, MN 55303 (763)205-2037 1111115 _A1111111121 1� m L.0'1' JJ N E' A DJAJ STF-." 2 0 FEE T 41 4911 AC'JK 7`0 REISM Xl",4, R.E'.,(6,R i -()T 116 NE 41% Description: .,Propos d PrelJ cU _e/qt Modificotioti for Hunters Pass Estates Second A d4Lt _iorL Dweb Scaha:: .1 100 raven By SD Checked By, SD Dat6: 11-12-2013 CESD Project ikon :00415 HUNTERS PASS ESTATES SECOND ADDITION Albertville-, MN Preliminary Plat Modification 14 EXHIBIT B Anoka, MN 65303 (763)205-2037 www,.toliberghomes.com . ii �iGf WA6f1"di4k'[�f.ZAdp1d'LVS' _ owAws ....--f� _ MOM" MW a eAtt+_ W 9PLErma au a I a uwo%�..-.-.
