RES-2020-0466a - Planning Recs with MapsMRC City of Omaha Planning Department Planning Board Memo To: Chairman and Members of the Planning Board From: David K. Fanslau Planning Director Date: July 31, 2019 Subject: Final Plat approval of LEGEND TRAILS (Lots 1-86, Outlots A-L), a subdivision outside the city limits, along with rezoning from AG-Agricultural District to DR- Development Reserve District. Northwest of 222nd and “Q” Streets Case #C10-18-166, C12-18-167 At the Planning Board meeting on June 5, 2019 the Final Plat approval for Legend Trails was laid over to allow the applicant time to address the conditions of the revised preliminary plat. The Revised Preliminary Plat of Legend Trails (Lots 1-86, Outlots A-L), with waivers of Section 53-8(2), Street width, Section 53-9(3), Curb and gutter, Section 53-9(9), Sidewalks; Section 53- 8(4)(d) Lot frontage; along with rezoning from AG to DR, was approved with conditions by the City Council on July 30, 2019. Subsequently, the applicant has submitted additional information including a slopes analysis and final wetland delineation report to address the conditions of the revised preliminary plat approval. The conditions of approval for the Revised Preliminary Plat are as follows (with subsequent responses for this review provided in italics): 1. Pave 222nd Street to a two-lane section along the subdivision’s frontage within two years of the recording of the plat. (The GO paving plan provides for a 25 foot wide paving along the frontage and will be addressed in the final subdivision agreement.) 2. Coordinate with Douglas County to grade the subdivision to match the ultimate profile of 222nd and Q Streets. (The final design and grading of 222nd and Q Streets will be addressed as part of the final subdivision agreement.) 3. Dedicate 50 feet of Right of Way along both Q Street and 222nd Street, widening to 60 feet within 300 feet of their intersection. (The final plat provides for the required dedication.) 4. Proposed site grades along the eastern and southern boundaries of the platting, adjacent to 222nd Street and Q Street, must be coordinated with the future improvement of those roadways. (The grades adjacent to 222nd and Q Streets must be addressed as part of the final subdivision agreement in coordination with the future improvements.) 5. Proposed street connections from the development to 222nd Street and Q Street will require permits from the Douglas County Engineer’s office. The cost of the roadway LEGEND TRAILS Lots (1-86 and Outlots A-L) Case Number: C10-18-166, C12-18-167 Page 2 MRC improvements for the street connections, if required, will be the responsibility of the developer. (This condition will be addressed as part of the final subdivision agreement and the applicant will be required to secure the necessary permits.) 6. Place a note on the plat that direct access to 222nd Street and Q Street, from the adjacent platted lots, will not be permitted. (The necessary notes are provided on the final plat.) 7. Temporary turn-arounds should be provided at the terminus of all temporarily dead- ended streets. (This condition must be addressed in the final subdivision agreement.) 8. If the subdivision will not be located in a Sanitary Improvement District (SID), a maintenance agreement will be required before Douglas County will provide routine maintenance of any public streets. If not located in a SID, major maintenance activities are the responsibility of the adjacent property owner. If streets are private, no maintenance agreement would be needed. (This condition must be addressed in the final subdivision agreement for 228th Street/Circle because it is proposed as a public street.) 9. Provide an updated NDEQ approval letter based on the revised layout or documentation from the NDEQ that the previous approval is acceptable. (The applicant has provided an updated NDEQ letter.) 10. Submit for review to the Douglas County Engineer’s Office storm sewer and/or drainage design computations and final plans that relate to the handling of roadway and site drainage along the development boundary adjacent to 222nd Street and Q Street. (This condition will be addressed as part of the final subdivision agreement.) 11. Provide sidewalks along the 222nd Street and Q Street frontages. (This condition will be addressed in the final subdivision agreement.) 12. Any grading, sewer or utility work carried out in conjunction with this development, in 222nd Street and Q Street right-of-ways, will require a permit(s) from the Douglas County Engineer’s office. (The applicant will be required to secure the necessary permits.) 13. Comply with all applicable stormwater management regulations, including no net increase in stormwater runoff and must treat the first ½” of stormwater for water quality. (This condition will be addressed in the final subdivision agreement.) 14. All trails, parks and open space not indicated on the Omaha Suburban Park Master Plan must be privately constructed, owned and maintained by the developer, homeowner’s association or other approved entity. (The final subdivision agreement must address these areas. The use, ownership and maintenance of all outlots must be adequately addressed in the final subdivision agreement.) 15. All drainageways must be placed in an outlot sized to accommodate either the 3:1+20’ section or the 100 year stormflow (whichever is greater). (The applicant has indicated that allow drainageways are in outlots.) 16. Provide for the use, ownership and maintenance of all outlots in the final subdivision agreement. (This condition will be addressed in the final subdivision agreement.) 17. Coordinate for the final approval of the inter-local agreement between the City of Omaha and Douglas County covering the area outside Omaha’s extraterritorial jurisdiction. (The Planning Board recommended approval of the inter-local agreement (#C3-19-090) at its June 5, 2019 meeting although as a result of the recent City Council approval of an annexation the extra-territorial jurisdiction for the city will expand to include the area covered by the agreement thereby making it unnecessary.) 18. Submit a letter confirming that acceptable emergency warning is being provided for the area. (The applicant has provided a letter from Douglas County Emergency LEGEND TRAILS Lots (1-86 and Outlots A-L) Case Number: C10-18-166, C12-18-167 Page 3 MRC Management Agency stating that installation of a new outdoor warning siren is not required.) 19. Submit a slopes analysis confirming that grading will not significantly impact environmental features. (A slopes analysis was submitted and is acceptable.) 20. Submit a final wetland analysis with the final plat and an acceptable mitigation plan, if necessary. (A final wetland analysis was submitted. The analysis determined that there are seven wetlands and two channels within the plat area. A total of 7.18 acres of wetland area was delineated in addition to other channel and water resources on the site. All wetland areas are assumed to be jurisdictional unless determined otherwise by the U.S Army Corp of Engineers. The majority of the wetland areas and other water resources identified by the report are located in and along the drainageway that generally bisects the site from north to south. Based on the information submitted all wetland areas are located within an outlot therefore no mitigation is required. 21. Submit a revised tree canopy analysis and mitigation plan, if necessary. (The applicant has submitted an updated tree canopy analysis for the site. Upon review it has been determined that based on the 636,628 square feet of tree canopy on the property and the 164,858 square feet of canopy to be removed with the project, a required tree mitigation area of 5,201 square feet or 21 trees must be provided. No mitigation plan has been submitted, therefore the applicant must coordinate with Planning staff regarding an acceptable tree canopy mitigation plan before the request can be forwarded to the City Council.) 22. An acceptable debt ratio is 4.0 percent or less. (This condition must be addressed in the final subdivision agreement.) The following additional comments are provided: • Omaha Public Power District has existing distribution equipment that runs through this site. The applicant must coordinate with OPPD on removal of this equipment. • The sight distance criteria to be used in the evaluation of the street connection will be AASHTO Stopping Sight Distance for 50 MPH (425 feet). ANALYSIS: Conditionally, the proposed subdivision and rezoning is consistent with the approved revised preliminary plat, carries out the goals and objectives of the City of Omaha Master Plan and Chapter 53, Subdivisions. RECOMMENDATION: Approval of the rezoning from AG to DR. Approval of the Final Plat, subject to the following prior to forwarding the request to City Council: 1. Submittal of a final acceptable subdivision agreement. 2. Submittal of an acceptable tree canopy mitigation plan.

He advised that this is a single family, residential development. Mr. Lang advised that each lot will be approximately 1.5 acres in size. He advised that the developer is in agreement with the items in the recommendation report. He stated that he understood that the preliminary plat, waivers, and rezoning are being recommended for approval with conditions, and the final plat is to be laid over. Mr. Lang stated that he and the project engineer, Don Heine of Thompson, Dreessen, and Dorner, were both available to answer any questions the Board may have. No one appeared in opposition. Mr. Eric Englund, Acting Assistant Director, stated that Mr. Lang was correct in understanding that all but the final plat are being recommended for approval at this time. He stated that the department recommended layover of the final plat to allow time for the applicant to submit slopes and wetland analyses and a tree mitigation plan and canopy analysis. Mr. Englund reminded the Board that the plan calls for 86 acreage lots and twelve outlots for open space. He stated that there a few subdivision waivers which are listed and most were approved the last time the preliminary plat was presented at Planning Board. Mr. Englund stated that due to the project being within the Elkhorn ex-urban zone in the Omaha Master Plan, the department is supportive of the waivers which include a reduction in street width, not providing curbs and gutters, not providing sidewalks in some locations, as well as a waiver of lot frontage in one of the outlots. Mr. Englund stated that he was available to answer any questions from the Board and that the department recommended approval of the preliminary plat, waivers, and rezoning subject to the conditions listed in the recommendation report, and layover of the final plat.
