PLANNING BOARD RECOMMENDATION: Approval, as recommended by the Planning Department, 7-0. (Revised Preliminary Plat – LEGEND TRAILS (Lots 1-86, Outlots A-L) – Outside City) MRC City of Omaha Planning Department Planning Board Memo To: Chairman and Members of the Planning Board From: David K. Fanslau Planning Director Date: May 29, 2019 Subject: Revised Preliminary and Final Plat approval of LEGEND TRAILS (Lots 1-86, Outlots A-L), a subdivision outside the city limits, with waivers of Section 53-8(2), Street width, Section 53-9(3) Curb and gutter, Section 53-9(9) Sidewalks and Section 53-8(4)(d) Lot frontage, 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 The Preliminary Plat of Legend Trails (Lots 1-86, Outlots A-K), a subdivision outside the city limits, with waivers to Section 53-8(2), Street width, Section 53-9(3) Curb and gutter and Section 53-9(9) Sidewalks, along with rezoning from AG to DR, was approved by City Council with conditions on November 6, 2018. Subsequently, the applicant has submitted for Revised Preliminary and Final Plat approval for the 152 acre site to allow for 86 single family residential lots and 12 outlots for open space, drainage, tree mitigation and access. The developable residential lots range in size from 1.0 to 2.2 acres, with the average lot size of 1.28 acres. This request proposes a modest redesign of the development by addressing a number of the conditions of the approved preliminary plat. The primary modifications proposed include: • Dedication of right-of-way for 228th Street on the west side of the site with vehicular access to the development moved further north off of Q Street; • The east/west P Plaza has been moved north of the MUD easement line that bisects the site from east to west (renamed Orchard Plaza); and • The private street access to the development from 222nd Street has also moved north of the MUD easement. In comparison to the approved preliminary plat these modifications still propose 86 residential lots, but one additional outlot. Public Improvements: Waiver Requests - Similar to the preliminary plat approval the following waiver requests are proposed to the regulations within Chapter 53, Subdivision: • Section 53-8(2)(g) Street width from 25 feet to 22 feet. LEGEND TRAILS Lots (1-86 and Outlots A-L) Case Number: C10-18-166, C12-18-167 Page 2 MRC • Section 53-9(3) Curb and gutter, not providing curb and gutters. • Section 53-9(9) Sidewalks, not providing sidewalks throughout the development. Considering the environmentally sensitive nature of the area, similar to the North Hills Environmental Resources Overlay District; the proposed large lot development; rural street section and privately owned and maintained streets, the requested waivers are acceptable. Sidewalks will be required along 222nd and Q Street frontages. An additional waiver to Section 53-8(4) Lot frontage is requested for Outlot E and is acceptable. Traffic and Circulation – The applicant must address the following: • Pave 222nd Street to a two-lane section along the subdivision’s frontage within two years of the recording of the plat. • Coordinate with Douglas County to grade the subdivision to match the ultimate profile of 222nd and Q Streets. • 50 feet of Right of Way shall be dedicated along both Q Street and 222nd Street, widening to 60 feet within 300 feet of their intersection. • Coordinate the proposed site grades along the eastern and southern boundaries of the platting, adjacent to 222nd Street and Q Street with the future improvement of those roadways. The applicant 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 222nd Street and Q Street improvements. Certification of the grade coordination will be required prior to the City of Omaha’s approval of the final plat. • The sight distance criteria to be used in the evaluation of the street connection will be AASHTO Stopping Sight Distance for 50 MPH design (425’). • The proposed street connections from the development to 222nd Street and Q 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 connections, if required, will be the responsibility of the developer. • A note must be placed on the plat that direct access to 222nd Street and Q Street, from the adjacent platted lots, will not be permitted. • Temporary turn-arounds should be provided at the terminus of all temporarily dead-ended streets. • 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. Sanitary Sewer – Private wastewater treatment (septic) systems are proposed to serve each lot. The applicant submitted a letter of approval from NDEQ for a prior layout of the subdivision. The applicant must either provide an updated approval letter from NDEQ for the current layout or provide documentation from the NDEQ that the prior approval is acceptable for the revised layout. LEGEND TRAILS Lots (1-86 and Outlots A-L) Case Number: C10-18-166, C12-18-167 Page 3 MRC Storm Sewer – 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 must be submitted for review to the Douglas County Engineer’s Office. Storm sewers must be provided as required. Sidewalks – A waiver of Section 53-9(9), Sidewalks is included with this request. A similar request was approved as part of the preliminary plat approval. This development is located within the Elkhorn Special Development Zone, which has similar characteristics and development challenges as the North Hills Environmental Resources Overlay District, therefore a waiver of sidewalks throughout the development is acceptable, although the applicant must construct sidewalks along the 222nd and Q Street frontages. Utilities: MUD easements have been mostly incorporated into Outlots G-I, although 20 feet of a force main easement along the north side of those outlots will not be included. All utilities must be provided to each lot throughout the subdivision as required by Chapter 53, Subdivisions, of the Omaha Municipal Code. Grading and Drainage: 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 project must 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. Parks and Open Space: 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. 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 must provide for the use, ownership and maintenance of all outlots in the final subdivision agreement. Emergency Management: No information was submitted regarding whether or not provisions need to be made to install a warning siren to serve this area. The applicant must contact the Douglas County Emergency Management office to arrange for the location of a warning siren, if needed, or a letter must be provided from Douglas County Emergency Management confirming that acceptable emergency warning is being provided for the area. Environmental: Slopes Analysis: A condition of preliminary plat approval required submittal of a slopes analysis, which has not been provided. A review of the grading plan based on the revised development layout appears to propose an increase in the amount of grading compared to the plans provided with the approved preliminary plat. A slopes analysis must be submitted to ensure that grading is not significantly impacting environmental features of the site. Grading in areas of existing LEGEND TRAILS Lots (1-86 and Outlots A-L) Case Number: C10-18-166, C12-18-167 Page 4 MRC slopes over 17 percent or adjacent to environmentally sensitive areas shall be minimized to the extent possible. Wetland Analysis: The applicant has not submitted a final wetland analysis which is a condition of preliminary plat approval. All wetland areas as determined by that final analysis must be either encapsulated within an outlot for protection or an acceptable mitigation plan must be submitted with the final plat. The final wetland analysis and mitigation plan, if necessary must be submitted for review before the final plat can proceed. Tree Canopy Analysis: The applicant has submitted a revised tree canopy analysis indicating that no mitigation is required. As part of the approved preliminary plat a tree canopy analysis provided at that time indicated that 104 mitigation trees were required. Submittal of a final tree canopy mitigation plan was a condition of preliminary plat approval. A review of the revised tree canopy analysis has determined that the applicant has added tree canopy area that does not meet the criteria for acceptable tree canopy. Also there may be areas of canopy that are not included in the revised analysis that should be included. Canopy located in lots designated for future home construction must be mitigated as there is no mechanism to prevent the future removal of the trees. The applicant must work with city staff on an acceptable revised tree canopy analysis and mitigation plan, if necessary. Noxious Weeds: The applicant has provided approval confirmation of a Noxious Weed Control Plan from Douglas County. Financing: The taxable valuation of the updated development is estimated at $38,700,000. The projected total general obligation debt is estimated at $429,500. Approximately $4,412,600 of the costs of the improvements will be privately financed. The projected debt ratio is estimated at 1.11 percent. An acceptable debt ratio is 4.0 percent or less. Land Use and Planning: The rezoning from AG to DR is consistent with the Future Land Use Element of the City’s Master Plan. A portion of the proposed plat area at the southwest corner of the development is currently within the jurisdiction of Douglas County. A concurrent request is on the agenda for approval of an interlocal agreement (#C3-19-090) to adjust the extraterritorial jurisdiction line for this area by incorporating the subject property into the City of Omaha’s extraterritorial jurisdiction and amending the necessary Master Plan maps to properly designate the additional area. A draft subdivision agreement for this layout has not been provided. A final subdivision agreement will be required to address conditions of the plat approval. ANALYSIS: Conditionally, the proposed rezoning and subdivision is consistent with and carries out the goals and objectives of the City of Omaha Master Plan and Chapter 53, Subdivisions. RECOMMENDATION: Approval of a waiver of Section 53-8(2)(g) Street width. Approval of a waiver of Section 53-9(3) Curb and gutter.

C10-18-166 C12-18-167 Krejci Development REQUEST: Revised Preliminary and Final Plat approval of LEGEND TRAILS (Lots 1-86, Outlots A-L), a subdivision outside the city limits, with waivers of Section 53-8(2), Street width, Section 53-9(3) Curb and gutter, Section 53- 9(9) Sidewalks and Section 53-8(4)(d) Lot frontage, along with rezoning from AG to DR LOCATION: Northwest of 222nd and Q Streets At the Planning Board meeting held June 5, 2019, Mr. Jim Lang, 8526 F Street, appeared before the board, in his role as attorney for the developer, to describe the details of the request. 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. Mr. Rosacker moved for approval of a waiver of Section 53-8(2)(g) Street width, approval of a waiver of Section 53-9(3) Curb and gutter, approval of a waiver of Section 53-9(9) Sidewalks, not providing sidewalks throughout the development, with the exception that sidewalks must be provided along the 222nd and Q Street frontages, approval of a waiver of Section 53-8(4) Lot frontage. Approval of the rezoning from AG to DR, and approval of the Revised Preliminary Plat, subject to the following conditions: 1. Pave 222nd Street to a two-lane section along the subdivision’s frontage within two years of the recording of the plat. 2. Coordinate with Douglas County to grade the subdivision to match the ultimate profile of 222nd and Q Streets. 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. 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. 5. Proposed street connections from the development to 222nd Street and Q Street will require permits from the Douglas County Engineer’s office.
