Pln584blj PJB City of Omaha Planning Department 1819 Farnam Street Suite 1100 Omaha, NE 68183 402-444-5150 Planning.CityofOmaha.org Date: August 30, 2023 Case Number: C10-23-221, C12-23-222 Applicant: Jasper Stone Partners Request: Preliminary Plat approval of BENNINGTON COTTAGES, a cluster subdivision outside city limits, with rezoning from AG to DR, R5, and R6, along with a waiver to Sections 53-8, Site Stopping Distance, and 53-9(9), Sidewalks. Location: Southwest of 168th and Abigail Streets I. GENERAL INFORMATION: Purpose: To allow for development of the site with a variety of residential uses. Existing Use(s): Undeveloped Existing Zoning: AG Adjacent Land Use(s): Adjacent Zoning North: Residential North: Bennington South: Undeveloped/Agricultural South: AG East: Undeveloped/Agricultural East: AG West: Undeveloped/Agricultural West: AG Future Land Use Designation(s): Low Density Residential Applicable Regulations: If approved, development of the site will be subject to the underlying DR, R5, and R6 zoning regulations, cluster regulations, and all other applicable regulations. No building permits will be issued based on a site plan that does not comply with the provisions of the Zoning Ordinance. II. SPECIAL INFORMATION: Site Characteristics: The subject site is approximately 18.4 acres and is currently zoned AG- Agricultural District. The site is part of two unplatted parcels. The property at 10650 North 168th Street is developed with an existing residence and multiple outbuildings. The adjacent parcel is undeveloped and has historically been used as a tree farm operation. The site is designated for Low density residential in the Omaha Master Plan. Development Proposal: The applicant proposes platting the site into 54 lots zoned as R5 for single family cottage style homes (Lots 3-56), two lots zoned as R6 for multi- family residential development (Lots 1-2), and seven outlots zoned as DR. The single family lots as well as Outlots B-G are proposed as part of a cluster subdivision. The project proposes to retain multiple existing structures on the property as part of this development. The two south most structures are shown in a BENNINGTON COTTAGES Case No.C10-23-221, C12-23-222 PJB Page: 2 platted lot and will be the caretaker's house and detached garage. The northern three existing structures are shown in an outlot and will be refinished and used for community spaces (garden shed, greenhouse, and small event barn). Public Improvements: Plat: Place a note on the plat that there shall be no direct access to 168th Street from Lots 1 or 2, and that Chicory Street at 168th Street will be restricted to right-in/right-out only upon future improvements to 168th Street. Traffic and Circulation: Provide traffic calming for all streets longer than 1000’. The on-street parking on Chicory Street must be diagonal. Coordinate with Public Works on the acceptability of the stopping sight distance waiver request. Construct the Chicory Street approach to 168th Street as a 25’ wide two- lane street with no median. Dedicate 50’ of ROW along 168th Street. Grant a 115 foot noise attenuation easement along the centerline of 168th Street, and show the standard easement language on the plat. Provide for the widening of 168th Street along the subdivision’s frontage, as well as the turn lane and taper for the northbound left turn lane at Chicory Street. Construct the private streets in Outlot C to City standards, per Chapter 53 of Municipal Code; grant utility and public sanitary sewer easements in the outlot. Coordinate with the Planning and Public Works Departments on the Complete Streets Design Guide Design Checklists. Proposed site grades along the eastern boundary of the platting, adjacent to 168th Street, must be coordinated with the future improvement of the roadway. The consultant will be required to submit cross section information, for review purposes, that shows the relationship of the proposed site grading to the existing and future 168th Street improvements. Certification of the grade coordination will be required prior to the County Engineer’s signing of the final plat. The proposed street connection from the development to 168th Street will require permits from the Douglas County Engineer’s office and must meet proper sight distance criteria and incorporate intersection improvements as required by current City/County Access Policy. The cost of the roadway improvements for the street connection, if required, will be the responsibility of the developer. The sight distance criteria to be used in BENNINGTON COTTAGES Case No.C10-23-221, C12-23-222 PJB Page: 3 the evaluation of the street connections, will be AASHTO Stopping Sight Distance for 50 MPH design (425’). Temporary turn-arounds must be provided at the terminus of all temporarily dead-ended streets. A provision must be included in the subdivision agreement that assigns responsibility for the routine maintenance and snow removal of the parking areas located on public right-of-way. If Bennington Cottages Addition will not be located in a Sanitary Improvement District, a maintenance agreement will be required before Douglas County will provide routine maintenance of public streets or request street lights on behalf of the Developer. If not located in a Sanitary Improvement District, major maintenance activities are the responsibility of the adjacent property owner. Sanitary Sewer: Construct public sanitary sewers to serve each lot. Submit the 30% design report for the sanitary sewer to the Public Works Design Division per Section 2.14 of the City’s Wastewater Collection Systems Design Manual. Storm Sewer: Storm sewer design computations and final plans must be submitted to the Douglas County Engineer’s office for review that relate to the handling of roadway and site drainage along the development boundaries adjacent to 168th Street. Sidewalks: The applicant is requesting a waiver of Section 53-9(9), Sidewalks, as part of this application. The city has historically supported sidewalk waiver requests for the private ways in similar cluster-style developments. The requested sidewalk waiver is acceptable for the private streets of the proposed development. However, sidewalks must be constructed along all public streets, including along the subdivision’s 168th Street frontage. It should also be noted that the cluster portion of the development includes a trail-like sidewalk system, which provides each cluster lot pedestrian access throughout the development. Utilities: Any grading, sewer or utility work carried out in conjunction with this development, in 168th Street right-of-way, will require a permit(s) from the Douglas County Engineer’s office. OPPD has existing single phase overhead. Coordinate with OPPD for removal or relocation. Grading and Drainage: Receive preliminary approval of the PCSMP from Public Works prior to the application for final plat approval; upload the drainage study and preliminary plans to Permix. The development must comply with all applicable stormwater management ordinances and policies, including providing for a no net BENNINGTON COTTAGES Case No.C10-23-221, C12-23-222 PJB Page: 4 increase in stormwater runoff and treatment of the first ½ inch of stormwater for water quality. Parks and Open Space: Parks, Recreation and Public Property: Coordinate with the adjacent SIDs to make improvements to park area #18. Contact the City of Omaha Park’s department for additional assistance. Trails and/or open space constructed within the development that are not part of the suburban park master plan shall be privately constructed and maintained by the developer, HOA or other approved entity. Outlots: Provide for the use, ownership, and maintenance of the outlots in the subdivision agreement. Environmental: Noxious Weeds: Nebraska Statute (2-955) states that property owners are responsible for the control of noxious weeds and to prevent noxious weed seeds from spreading onto adjoining properties. The applicant will be required to submit a letter of approval from Douglas County for a Noxious Weed Plan. Tree Canopy/Wetlands: The PCSMP and Drainage exhibits show delineated wetlands in Outlot B with drainage running through lots 45-47. A wetland and waters of the U.S. delineation analysis is required to be submitted with the final plat. The inclusion of a Threatened and Endangered Species Evaluation summary from the Nebraska Conservation and Environmental Review Tool (Nebraska CERT) is recommended for all wetlands delineation reports. Much of the existing canopy was planted as farmstead windbreaks. The tree canopy analysis is acceptable, with one mitigation tree required. Mitigation trees must be planted within an outlot or common area separate from detention basin outlots and may not impede maintenance access to stormwater detention basins. Emergency Management: The applicant will be required to submit a letter from Douglas County Emergency Management confirming that acceptable emergency warning is being provided for the area. Financing: The proposed development will be privately funded. Land Use and Planning: Cluster Development: The applicant’s proposed cluster style of development for Lots 3-56 and Outlots B-G allows properties to be clustered or grouped to provide for greater flexibility in design and development of subdivisions to: (1) produce innovative environments, (2) provide for more efficient use of land, (3) protect topographical features, (4) permit common open space, and (5) permit private pedestrian and vehicular access. Cluster subdivisions allow for exceptions to minimum lot width and lot area to be reduced below that required for the base zoning district and that there is no minimum lot depth requirement. This part of the project proposes a density of approximately 7,900 square feet per unit, which is acceptable in the R5 District. The R5 District regulations allow for the Single-family residential (detached) use as proposed with this portion of the development. The proposed rezoning from AG to DR and R5 for the single-family lots and outlots is appropriate, BENNINGTON COTTAGES Case No.C10-23-221, C12-23-222 PJB Page: 5 given the Low Density Residential designation for the site in the Omaha Master Plan. Cluster subdivisions must comply with Section 55-784, which provides for exceptions to the normal site development regulations of the base zoning district, including: ● Perimeter yards (setback) from a public street of the larger of 25 feet or the required front yard setback for the zoning district. ● Perimeter yards (setback) from any property line forming the boundary of the subdivision of 20 feet ● Individual cluster lots are exempt from minimum lot area and yard setbacks although a minimum separation of 6 feet and average of 10 feet shall be established between all residential structures not attached to each other. ● Individual cluster lots are exempt from minimum building and impervious coverage and street yard landscaping regulations. However, the cluster subdivision as a whole, including streets, access ways and other paved surfaces, must comply with the building and impervious surface coverages of the R5 District. The applicant has provided documentation estimating the building and impervious coverage for the overall development in compliance with the R5 maximum of 50 percent for building coverage and 60 percent for impervious coverage. A minimum 25 foot setback is required for the proposed garages to the adjacent private ways per Section 55-784 (d)(2) Exceptions to site development regulations for cluster subdivisions of the Omaha Municipal Code. The applicant is proposing reducing setbacks for the proposed garages to the adjacent accessways to approximately 5 feet, noting this is to discourage residents from parking vehicles in their driveways. A waiver of this zoning code section can be supported due to the fact that they are internal to the site and if the development were to be proposed as a single lot, the site would be in compliance with this zoning regulation. The applicant must obtain the necessary garage setback waiver from the Zoning Board of Appeals (prior to submitting for building permit). A minimum 25 foot setback is required to the adjacent public streets per Section 55-784 (c)(1), Exceptions to site development regulations for cluster subdivisions of the Omaha Municipal Code. The applicant is proposing an approximately 19 foot setback for various structures to the property lines abutting Chicory and 171st Streets, which are public streets. A reduction in this setback requirement can be supported as this setback would be consistent with the standard street yard setback for a single- family home in the R5 District. The applicant must obtain the necessary waiver from the Zoning Board of Appeals (prior to submitting for building permit). Multi-family Development: The subject site is designated for low-density residential development in the Future Land Use element of the Omaha BENNINGTON COTTAGES Case No.C10-23-221, C12-23-222 PJB Page: 6 Master Plan. However, the Master Plan allows for groupings of 100 multi- family units outside of the density corridors and away from the office, commercial or civic portions of a mixed-use area, provided it is more than a quarter mile away from the nearest multi-family development. The subject site is more than a quarter mile away from any adjacent multi- family development and the R6-zoned portion of the development is 4.1 acres, which would limit the number of possible multi-family units to 89, per the allowed density in the R6 district. The proposed R6 zoning for Lots 1 and 2 is acceptable. Existing Structures: The applicant will need to coordinate with the city on the existing structures being retained within the outlot, the acceptability of the proposed uses, and the associated language to be included in the final subdivision agreement. These buildings cannot be used for commercial purposes. Street Names: Coordinate with Planning staff on appropriate street names within the development. III. ANALYSIS: Conditionally, the proposed subdivision and rezoning comply with the requirements of Chapter 53 Subdivisions of the Omaha Municipal Code and the City’s Master Plan. IV. RECOMMENDATIONS: Approval of the waiver of Section 53-9(9) Sidewalks, for the proposed privates streets. Approval of the Preliminary Plat, subject to the following conditions: 1. Place a note on the plat that there shall be no direct access to 168th Street from Lots 1 or 2, and that Chicory Street at 168th Street will be restricted to right-in/right-out only upon future improvements to 168th Street. 2. Provide traffic calming for all streets longer than 1000’. 3. The on-street parking on Chicory Street must be diagonal. 4. Coordinate with Public Works on the acceptability of the stopping sight distance waiver request. 5. Construct the Chicory Street approach to 168th Street as a 25’ wide two-lane street with no median. 6. Dedicate 50’ of ROW along 168th Street. 7. Grant a 115 foot noise attenuation easement along the centerline of 168th Street, and show the standard easement language on the plat. 8. Provide for the widening of 168th Street along the subdivision’s frontage, as well as the turn lane and taper for the northbound left turn lane at Chicory Street. 9.

C10-23-221 C12-23-222 Jasper Stone Partners REQUEST: Preliminary Plat approval of BENNINGTON COTTAGES, a cluster subdivision outside city limits, with rezoning from AG to DR, R5, and R6, along with a waiver to Sections 53-8, Site Stopping Distance, and 53-9(9), Sidewalks LOCATION: Southwest of 168th and Abigail Streets At the Planning Board meeting held September 6, 2023, Bradley Huyck, 10836 Old Mill Road, TD2 Engineering, appeared before the Board on behalf of the applicant. DJ Hinman, 16820 Frances Street Suite 206, appeared before the Board. Mr. Hinman stated that this property was a tree farm. He stated that they plan to keep the trees and grading. In response to Mr. Pate, Mr. Hinman stated that this is a single-family detached project with homes that are smaller in scale. He stated the homes will be 700 to 1000 square feet. Jared Kutschara, 107 Abigail Street, appeared before the Board. Mr. Kutschara stated his concerns are lights, privacy, and noise. Eric Englund, Assistant Director, appeared before the Board on behalf of the Planning Department. Mr. Englund stated that the Preliminary Plat is also a cluster subdivision. He stated that the site is 18 ½ acres, 54 lots, two multi-family lots, seven outlots. He discussed the public right-of-way streets and private streets going through the proposed plan. Mr. Englund further detailed the unique layout of the cluster subdivision in regards to the types of waivers being requested including the sidewalk waiver for the internal private street. He stated that Public Works will continue to coordinate with the development team on the stopping site distance waiver which will be a continued item. Mr. Englund also stated that there are some outstanding items standard with a Preliminary Plat i ncluding a full Wetlands analysis and items that need the Zoning Board of Appeals regarding setback waivers as it relates to the cluster subdivision. He stated that there will need to be coordination on final language regarding the request to preserve the outbuildings for community use. He briefly touched on the multi-family use portion of the plan stating that it is Master Plan compliant.
