RES 2019-0881a - 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: February 27, 2019 Subject: ANTLER VIEW EAST (Lots 1-11 and Outlots A-E) Southwest of 180th and West Maple Road Case #C10-17-046, #C12-17-047 The Preliminary Plat of Antler View East was originally approved with conditions by the City Council at its July 11, 2017 meeting. A Revised Preliminary Plat for Antler View East was recommended for approval by the Planning Board at its February 6, 2019 meeting. The Final Plat of Antler View East (Lots 1-11 and Outlots A-E) was laid over by the Planning Board at its February 6, 2019 meeting to allow the applicant time to address the conditions of the Revised Preliminary Plat approval. The applicant has subsequently submitted updated final plat plans for review. The conditions of approval of the Revised Preliminary Plat are listed below (with subsequent responses for this review included in italics): 1. Provide for all improvements identified in the final approved traffic study. (This will be addressed in the final subdivision agreement.) 2. Coordinating with the Public Works Department and the Nebraska Department of Roads regarding West Maple Road improvements. (This will be addressed in the final subdivision agreement. All appropriate permits must be approved prior to construction of any improvements in the West Maple Road right-of-way.) 3. The applicant must pave Emmet Street as a stub street to the subdivision boundary, and provide for proper signage and other measures to prohibit access to 180th Street. Douglas County will make this connection at the time of their future 180th Street project. (This will be addressed with a future phase of the development.) 4. The applicant must coordinate with Public Works on an acceptable design for the roundabouts. (This will be addressed in the final subdivision agreement.) 5. Reduce the median width on the north leg of 183rd and Evans to 4 feet (paved), and remove the median on the south leg. (Medians have been revised accordingly.) 6. Coordinate with Public Works for an appropriate location and design for the southbound 183rd Street lane drop south of Evans Street. (This will be addressed in the final subdivision agreement.) 7. Providing a contribution toward the 180th Street bridge project. (A contribution is shown in the subdivision agreement and will be addressed in the final subdivision agreement.) 8. Providing a dedication of right-of-way along 180th Street 75’ from the centerline and coordinating with Douglas County regarding the extent of the future right-of-way acquisitions along 180th Street. (This will be addressed with a future phase of the ANTLER VIEW EAST (Lots 1-11 and Outlots A-E) Case Number: C10-17-046, C12-17-047 Page 2 MRC development although the applicant indicates that the current right-of-way width is in excess of 75’ from the existing centerline of 180th Street and per Douglas County plans 180th Street is anticipated to shift east which will provide additional right-of-way along the frontage of Antler View East.) 9. Storm sewer design computations and final plans must be submitted to the Douglas County Engineer’s office for review. (The applicant must continue to coordinate with Douglas County regarding this issue.) 10. Proposed site grades along the eastern boundary of the platting, adjacent to 180th Street, must be coordinated with the future improvement of the roadway. (This will be addressed with a future phase of the development although the applicant states that due to the unnamed creek located along the east side of the property proposed grades are not anticipated to have any effect on the future 180th Street improvements. The Emmet Street connection and on-site grading must be coordinated with Douglas County.) 11. Coordinating with the Public Works Department regarding an acceptable general obligation paving plan. (This will be addressed in the final subdivision agreement.) 12. Placing a note on the final plat stating that there shall be no direct access from any lot within the subdivision to 180th Street or West Maple Road, and providing a note final plat stating that there shall be no direct access from Lot 9 or 12 to 183rd Street. (The applicable notes for access to West Maple Road and 182nd Avenue are provided on the final plat.) 13. Providing an access easement to Outlot D (the green corner) from 181st/Evans Streets. (This will be addressed with a future phase of the development.) 14. Aligning the proposed access to Lot 19 with 181st Street or moving it to the east as a right-in/right-out only access. (The access has been moved east as a right-in/right-out only access.) 15. Obtaining all of the appropriate permits from Douglas County. (The applicant will need to continue to coordinate with Douglas County to obtain the appropriate permits.) 16. Coordinate with Omaha Public Power District regarding any grading or construction in their easements. (The applicant has indicated that coordination is on-going.) 17. Providing temporary turnarounds at the terminus of all temporarily dead-end streets. (This will be addressed in the final subdivision agreement.) 18. Providing sidewalks along all street frontages in compliance with city code. (The applicant must continue to coordinate with Planning, Parks and Public Works regarding sidewalks. This will be addressed in the final subdivision agreement and Mixed Use District Development Agreement.) 19. Coordinate with the Douglas County Engineer’s office regarding grading the subdivision to match the ultimate profile of 180th Street. (The applicant must continue to coordinate with Douglas County regarding the grading of the ultimate profile of 180th Street.) 20. Including the drainageway within the subdivision in an outlot sized to accommodate either the 3:1 plus 20’ section or the 100-year storm flow; whichever is greater. (The outlots have been revised to include the 3:1 + 20’ section.) 21. Compliance with all applicable stormwater management ordinances and policies; including providing for a no net increase in stormwater runoff and treatment of the first ½ inch of stormwater for water quality. (This will be addressed in the final subdivision agreement although the plans provide for a number of sediment control basins.) 22. Providing the 35 foot wide no build easement along the parkway, as required, including adjacent to Outlots A and B. (A 35 foot wide no-build setback was shown along the parkway on the final plat, but this must be listed as an easement not a setback.) 23. Plans and specifications for the design of Big Elk Parkway must be submitted for review to the Park Board prior to bidding. (The Parks Department states that Big Elk Parkway needs to be shown/designed per the Suburban Park Master Plan requirements. Street trees and other amenities need to be shown. The sidewalk along the north side of Big Elk needs to continue eastward toward the round-a-bout. As mentioned previously ANTLER VIEW EAST (Lots 1-11 and Outlots A-E) Case Number: C10-17-046, C12-17-047 Page 3 MRC Parkway plans and specifications (min. 60% complete) must be submitted for review to the Park Board prior to bidding.) 24. The applicant must provide an outlot along the north side of the parkway and provide an acceptable landscape plan to screen the rear of the building from the parkway or work with the Parks and Planning Departments regarding an acceptable alternative solution. (The applicant has provided a 35 foot wide no build setback (must show as an easement) within Outlot E along the north side of the parkway along with a berm and landscaping. The Parks Department has stated that the berming/ landscaping as shown on Exhibit B is unacceptable to properly screen the rear of the building on Lot 10 from the Parkway. The outlot may need to be enlarged to provide enough space to accommodate additional berming along with a staggered, multi-row planting scheme using evergreens and deciduous trees. The applicant must coordinate with the Parks Department regarding an acceptable berm/landscape plan to screen the rear elevation of the building on Lot 10 from view from the Parkway.) 25. Remove the driveway access from the parkway to Lot 10. (The driveway from the parkway has been removed.) 26. 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. (This condition must be addressed in the final subdivision agreement or the final Mixed Use District Development Agreement.) 27. Correct the final plat mylars to show 185th Street as 182nd Avenue. (The street name has been corrected on the final plat mylars.) 28. Include provisions for the use, ownership, and maintenance of the outlots in the final subdivision agreement. (This must be adequately addressed in the final subdivision agreement.) 29. Submittal of an acceptable final wetland analysis and mitigation plan, if necessary. (The applicant submitted a final wetland analysis. The final report found four wetland areas and two channels delineated within the overall site. The delineated wetlands are PEMA/PEMC and PFOA wetlands, primarily located in drainage pathways along the edges of the adjacent agricultural fields. The delineated channels include two unnamed tributaries to the West Papillion Creek. An erosional feature was found on Lot 11, but it is considered a non-wetland water resource. Most of the delineated wetland areas and channels are encapsulated within outlots although wetland area impacted by the Evans Street crossing with along adjacent grading within the southern portion of Outlot A and northern portion of Outlot B must be mitigated. The approximate area impacted is 6,400 square feet (0.15 acres), which must be adequately mitigated within an outlot at a 1:3 ratio (0.45 acres). The applicant must submit an acceptable wetland mitigation plan prior to forwarding the request to the City Council. Additionally the applicant has stated that the wetland on Lot 11 is non-jurisdictional although during the permitting process through the U.S. Army Corps of Engineers, if the wetland is determined to be jurisdictional the applicant must submit an acceptable updated wetland mitigation plan at a 1:3 ratio for that area disturbed on Lot 11.) 30. Submittal of an acceptable updated tree canopy analysis and mitigation plan, if necessary. (Approximately 18,000 square feet of tree canopy qualifies as being removed as a result of being in the right-of-way. The applicant must adjust the table on the tree canopy analysis to reflect this and the additional mitigation trees required as a result. The tree mitigation plan is not acceptable as shown. The trees must be grouped in a manner that recreates the canopy that was removed and not placed in a linear fashion. The tree species proposed for mitigation must also be included on the planting plan. The applicant must work with the Planning Department staff on an acceptable tree canopy analysis and mitigation plan prior to forwarding this request to the City Council.) ANTLER VIEW EAST (Lots 1-11 and Outlots A-E) Case Number: C10-17-046, C12-17-047 Page 4 MRC 31. Submittal of a letter from Douglas County Emergency Management confirming that acceptable emergency warning is provided for the area. (A letter has not been provided and must be submitted prior to the request being forwarded to the City Council.) 32. Submittal of a letter of approval of a Noxious Weed Plan from Douglas County. (A signed plan has been submitted.) 33. An acceptable debt ratio of 4% or less. (The taxable valuation for the overall development is estimated at $175,697,750, which includes valuation from the Antler View development to the west. The projected total general obligation debt is estimated at $6,739,520, which also includes debt from the Antler View development to the west. The projected overall debt ratio is estimated at 3.84 percent. The taxable valuation for Antler View East Phase 1 is estimated at $24,880,500. The general obligation debt is estimated at $1,640,500. The projected debt ratio for Phase 1 is estimated at 6.59 percent. The taxable valuation for Antler View East Phase 2 is estimated at $34,328,250. The total general obligation debt for Phase 2 is estimated at $1,765,700. The projected debt ratio for Phase 2 is estimated at 5.14 percent. An overall debt ratio of 4 percent or less is required. This will be addressed in the final subdivision agreement.) Land Use and Planning: The intersection of 180th Street and West Maple Road is designated as a Community (165 acre) Mixed Use Area. Based on the updated plans, this development proposes 56.37 acres of mixed use development. Currently, there is a total of 44 acres accounted for at this intersection with 21.0 acres allocated to Thomsen Mile West and 22.86 acres allocated to Maple 180 (Northeast corner). If this project is approved, approximately 100.4 acres of the 165 available acres would be allocated at this intersection, leaving approximately 64.6 acres available to the northwest and southeast corners of the intersection. Mixed Use Plan/Agreement related comments: Based on the updated development plan, the Mixed Use Agreement and Exhibits B must be revised to accurately address the following: Agreement and exhibits: • The proposed development plan and agreement or amendments to such are presumed to illustrate intent to comply with applicable provisions of the section 55- 561 related to Mixed Use Districts.

Providing proper signage and employing other measures to prohibit access to 180th Street from Emmet Street until Douglas County makes the connection, in the future, with their 180th Street improvement project. (Since the existing bridge on 180th Street is in close proximity to Emmet Street it will preclude 180th Street left turn lanes at the intersection, therefore Emmet Street will not be permitted to connect to 180th Street at this time. The applicant must pave Emmet Street as a stub street to the subdivision boundary, and provide for proper signage and other measures to prohibit access to 180th Street. Douglas County will make this connection at the time of their future 180th Street project.) 4. Providing a contribution toward the 180th Street bridge project. (Condition is still applicable.) 5. Providing a dedication of right-of-way along 180th Street 75’ from the centerline and coordinating with Douglas County regarding the extent of the future right-of-way acquisitions along 180th Street. (Condition is still applicable). 6. Coordinating with the Public Works Department regarding an acceptable general obligation paving plan. (Condition is still applicable.) 7. Placing a note on the final plat stating that there shall be no direct access from any lot within the subdivision to 180th Street or West Maple Road, and providing a note final plat stating that there shall be no direct access from Lot 5 or 6 to 183rd Street. (Condition is still applicable although change note for no direct access from Lots 9 or 12 to 183rd Street.) 8. Providing an access easement to Outlot F (the green corner) from 181st/Evans Streets. (Condition is still applicable although is now Outlot D (green corner).) 9. Aligning the proposed access to Lot 11 with 181st Street or moving it to the east as a right-in/right-out only access. (Condition is still applicable although now Lot 19.) 10. Obtaining all of the appropriate permits from Douglas County. (Condition still applicable.) 11. Providing temporary turnarounds at the terminus of all temporarily dead-end streets. (Condition is still applicable.) ANTLER VIEW EAST Case Number: C10-17-046, C12-17-047 Page 2 MRC 12. Providing sidewalks in compliance with (Chapter 53 Subdivisions and Chapter 55 Zoning), and providing six foot wide sidewalks on each side of the parkway per the Suburban Parks Master Plan. (Sidewalks are required along all street frontages. Seven foot wide sidewalks are shown along Big Elk Parkway and other internal streets. To maintain consistency, change the sidewalk width along Big Elk to six foot (both sides). Also, a six foot sidewalk is required along Outlot A adjacent to Big Elk Parkway.) 13. Grading the subdivision to match the ultimate profile of 180th Street. (Condition is still applicable, coordinate with Douglas County Engineer’s Office.) 14. Including the drainageway within the subdivision in an outlot sized to accommodate either the 3:1 plus 20’ section or the 100-year storm flow; whichever is greater. (Condition is still applicable.) 15. Compliance with all applicable stormwater management ordinances and policies; including providing for a no net increase in stormwater runoff and treatment of the first ½ inch of stormwater for water quality. (Condition is still applicable.) 16. Providing the 35 foot wide no build easement along parkway, as required. (The “35’ no- build setback line” needs to be changed to 35’ no-build easement. The no-build easement needs to be shown along Big Elk Parkway adjacent to Outlot A & B as well.) 17. Including provisions for the use, ownership, and maintenance of the outlots in the final subdivision agreement. (Condition is still applicable.) 18. Submittal of an acceptable final wetland analysis and mitigation plan, if necessary. (The applicant has submitted a preliminary wetland analysis for review and comments are provided below.) 19. Submittal of an acceptable tree canopy mitigation plan. (A tree canopy analysis was submitted and the review comments are provided below.) 20. Submittal of a letter from Douglas County Emergency Management confirming that acceptable emergency warning is provided for the area. (Condition is still applicable.) 21. An acceptable debt ratio of 4% or less. (Condition is still applicable.) 22. A revised preliminary plat if necessitated by lot layout and/or right-of-way changes. The applicant has submitted a request for a Revised Preliminary Plat approval of Antler View East, with rezoning from AG-Agricultural District and R4-Single Family Residential District (High Density) to DR-Development Reserve District, R4-Single Family Residential District and MU- Mixed Use District as a phased development A request is also submitted for Final Plat approval of Antler View East (Lots 1-11, Outlots A-C), with rezoning from AG and R4 to DR, R4 and MU (Phase 1 of the development). Generally, phase 1 of the development is on the west side of 183rd Street and phase 2 is the east side. The proposed Revised Preliminary plat contains 80.12 acres and the plat area has been expanded to include land south of Big Elk Parkway near 183rd Street, which was previously platted as part the Spruce 180 development (Lots 77-79 and 89-91). With the expanded plat area the applicant proposes a revised location/design for the round-about at 183rd Street and Big Elk Parkway/Emmet Street. The revised plat proposes 16 lots for mixed use development (58.61 acres), three lots for single family residential (1.09) and seven outlots (10.28 acres) for open space and drainage purposes. The remaining 10.04 acres is for right-of-way purposes. The proposed Final Plat (Phase 1) request consists of 47.93 acres and includes the single family residential Lots 1-3, a portion of the mixed use development including Lots 4-11 (34.17 acres) and Outlots A-C (6.67 acres). The remaining 6.0 acres is for right-of-way purposes. ANTLER VIEW EAST Case Number: C10-17-046, C12-17-047 Page 3 MRC The following additional comments are provided based on a review of the current submittal: Public Improvements: Traffic and Circulation: • The applicant must coordinate with Public Works on an acceptable design for the roundabouts. • Reduce the median width on the north leg of 183rd and Evans to 4 feet (paved), and remove the median on the south leg. • Coordinate with Public Works for an appropriate location and design for the southbound 183rd Street lane drop south of Evans Street. • The proposed street connections from the development to 180th 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. The sight distance criteria to be used in the evaluation, of the driveway connections, will be AASHTO Stopping Sight Distance for 50 MPH design (425’). 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 boundary adjacent to 180th Street. Grading and Drainage: • Proposed site grades along the eastern boundary of the platting, adjacent to 180th Street, must be coordinated with the future improvement of the roadway. 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 180th Street improvements. Certification of the grade coordination will be required prior to the City of Omaha’s approval of the final plat. • Any grading, sewer or utility work carried out in conjunction with this development, in 180th Street right-of-way, will require a permit(s) from the Douglas County Engineer’s office. • A sediment basin is shown on the Grading Plan at the southwest corner of Lot 10. If this is a permanent stormwater detention basin it appears to be in conflict with the proposed improvements on the site. Utilities: The applicant must be aware that Omaha Public Power District (OPPD) has a multiple transmission easements along the west side of the development and OPPD must be contacted if any grading/construction is proposed within these easements. Parks and Open Space: • Plans and specifications for the design of Big Elk Parkway must be submitted for review to the Park Board prior to bidding. • It appears that the large retail building located in Lot 10 has the rear elevation facing Big Elk Parkway. Rear facing buildings/lots are typically not allowed along boulevards or parkways. Only front or side yards adjacent to the boulevard or parkway are allowed. To mitigate this issue an outlot must be provided consisting of a portion of the proposed Lot 10 that abuts the parkway, west of 183rd Street. This outlot must be of sufficient size to allow the installation of berming and landscaping that will provide a visual screen barrier of the rear of the building from the parkway. The landscape plan must be approved by the Planning and Parks Departments, incorporated into the mixed use ANTLER VIEW EAST Case Number: C10-17-046, C12-17-047 Page 4 MRC agreement and maintained by the developer or other acceptable entity. The driveway from the parkway to the parking lot must be removed. • 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. Environmental: • Wetland Analysis: The applicant has submitted a preliminary wetland report for review. The report found six (6) wetlands totaling 2.94 acres and two (2) channels located within the study area. The report states that the delineated wetlands were primarily located along channels or drainage pathways adjacent to the agricultural field, with the only exception being a small, isolated dry stormwater detention cell. A wetland exhibit provided by the applicant indicates areas of wetland that are not encapsulated within an outlot. While the applicant states that impacts to the wetland and channel resulting from the project appear to fall under Nationwide Permit No. 29 for residential developments, a final wetland report must be submitted for review along with a mitigation plan, if necessary, before the final plat can be recommended for approval. Either the lot lines must be adjusted to incorporate those wetland areas into an outlot for protection or the wetland areas that are being disturbed must be mitigated at a 1:3 ratio. • Tree Canopy Analysis: An updated tree canopy analysis was submitted for review. Historic aerial photos indicate that as recently as 1993 most of this area was devoid of trees. The intent of the Master Plan related to tree mitigation is to mitigate areas of tree canopy that have been established for a long period of time. Considering the history of this area mitigation as shown by the applicant is not required. In general though it should be noted that labelling a tree species as “undesirable” and removing it for farm maintenance does not exempt it from mitigation requirements. Upon staff review it is determined that an updated tree canopy analysis and mitigation plan (if necessary) must be submitted. The updated analysis must address the following: 1) Address the historic tree canopy of the site as described above; 2) To protect tree canopy proposed to be undisturbed either Outlot D or E must be expanded to include the area within Lot 16 where trees are being proposed as preserved; and 3) All areas within the tree canopy on the eastern edge of the site that overlaps with the grading plan should be shown as removed and mitigated. • 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. A letter of approval of a Noxious Weed Plan from Douglas County is required. Financing: The taxable valuation for the overall development is estimated at $162,801,500, which includes valuation from the Antler View development to the west. The projected total general obligation debt is estimated at $6,503,720, which also includes debt from the Antler View development to the west. The projected overall debt ratio is estimated at 3.99 percent. It is unclear in the information provided by the applicant if the valuation provided is the 95 percent valuation used to calculate the debt ratio. The taxable valuation for Antler View East Phase 1 is estimated at $24,880,500. The general obligation debt is estimated at $1,640,500. The projected debt ratio for Phase 1 is estimated at 6.59 percent. The taxable valuation for Antler View East Phase 2 is estimated at $34,328,250. ANTLER VIEW EAST Case Number: C10-17-046, C12-17-047 Page 5 MRC The total general obligation debt for Phase 2 is estimated at $1,529,900. The projected debt ratio for Phase 2 is estimated at 4.46 percent. An overall debt ratio of 4 percent or less is required. Land Use and Planning: • The intersection of 180th Street and West Maple Road is designated as a Community (165 acre) Mixed Use Area. This development proposes 58.61 acres of mixed use development. Currently, there is a total of 44 acres accounted for at this intersection with 21.0 acres allocated to Thomsen Mile West and 22.86 acres allocated to Maple 180 (Northeast corner). If this project is approved, approximately 103 acres of the 165 available acres would be allocated at this intersection, leaving approximately 62 acres available to the northwest and southeast corners of the intersection. • The final plat mylars must change 185th Street to 182nd Avenue (shown as 183rd Street on the Revised Preliminary Plat). All comments in the report refer to the street name as shown on the submitted plans, not the corrected street name. Mixed Use Plan/Agreement related comments: The Mixed Use Agreement and Exhibits B must be revised to accurately address the following: Agreement and exhibits: • The proposed development plan and agreement or amendments to such are presumed to illustrate intent to comply with applicable provisions of the section 55- 561 related to Mixed Use Districts. Any deviation from applicable code should be explicitly defined, enumerated and detailed in; Section 4 of the development agreement, as a separate exhibit included in the development agreement or as an integral part of the Development Plan. • On the mixed use plan, coordinate with Planning and Public Works on an acceptable access configuration for Lots 10 and 17. • Provisions for conditional uses must be removed from the development plan and agreement under section 3E. Such uses may be allowed under a subsequent major amendment when accompanied by a detailed and final site plan pursuant to section 55-563(e). • All signage must comply with regulations in Chapter 55. No signage is allowed within the street right-of-way. Streets: • The MU district should incorporate an internal street system and may include Main streets, Internal streets or Access drives pursuant to section 55-930.b.4 and Fig. 55- 32. Street types should be identified on exhibit “B” or by separate exhibit. • MU exhibits should include all proposed street sections demonstrating compliance with MU sidewalk standards pursuant to section 55-924 and including the proposed sidewalk/trail network. The sidewalk/trail shall include OPPD standard “Acorn” pedestrian scaled light fixtures when adjacent to streets. Locations should be provided on exhibit “B”. Open space / Plaza: • Plaza and Open Space are separate requirements outlined in Sections 55-564(e) and (h) and must be delineated individually on Exhibit B. • The proposed plaza areas must be provided dimensions and area call-outs on exhibit “B”.

C10-17-046 C12-17-047 180 Maple LLC REQUEST: Final Plat approval of ANTLER VIEW EAST (Lots 1-11 and Outlots A-E), a subdivision outside the city limits, with rezoning from AG and R4 to DR, R4 and MU (laid over from 2/6/19) LOCATION: Southwest of 180th Street and West Maple Road At the Planning Board meeting held March 6, 2019, Mr. Eric Englund, Manager of Current Planning, advised that the Planning Board had recommended approval of the revised preliminary plat at the February 6, 2019 meeting. At the same meeting, he advised, the Planning Board laid over the final plat of the first phase to address a few items. The first phase, final plat including 11 lots and 5 outlots is back today with the recommended changes from the layover last month. He stated that one of the issues was to adequately address all of the proposed wetland areas, either through incorporating them in an outlot or to properly mitigate them. Mr. Englund stated that one of the outlots on the west portion has been enlarged to encapsulate most of those wetlands. He stated that the second item dealt with the south side of lot 10 fronting on the parkway. Mr. Englund explained that in order to adequately buffer the proposed use, the plan now proposes an outlot with heavy landscaping and no access drives from the parkway to lot 10. There are a few issues to be addressed with the Parks department before going to City Council, and some minor mixed use items that will need to be updated before the Mixed Use Development Plan can be forwarded to the City Council for final approval. With these items in mind, however, the Planning Department is recommending approval. Mr. Rosacker moved for approval of the rezoning from AG and R4 to DR, R4 and MU, subject to submittal of an acceptable final Mixed Use District Development Agreement. Approval of the final plat, subject to addressing the conditions of revised preliminary plat approval and submittal of a final acceptable subdivision agreement, prior to forwarding this request to the City Council. Mr. Moore seconded the motion which carried 7-0.
