Development
Proposal:
At the July 6, 2022 meeting, the Planning Board laid over this request for
Preliminary Plat approval of PURPLE MARTIN HILL, a subdivision outside
city limits, with rezoning from AG to DR and R6, along with expansion of
the MCC-Major Commercial Corridor Overlay District for a portion of the
site, to allow the applicant time to submit additional documentation related
to PCSMP as well as to hold a neighborhood meeting with adjacent
property owners.
The applicant has since submitted the necessary PCSMP materials and
also held a neighborhood meeting on July 20, 2022.
The applicant still proposes to subdivide the property into two lots and one
outlot in two phases of development.

PJB
The first phase of development (Lot 1 & OL A) comprises the west half of
the subdivision and proposes construction of a 48-unit single-story
affordable apartment complex and limited surface parking for
developmentally disabled individuals. Outlot A is designated for drainage
purposes and would also include a driveway connection for the proposed
apartment complex to the adjacent street. 182nd Street will be extended
as part of phase one, providing the required north/south through-route
connection from Fort Street to Ida Street. Both Lot 1 and Outlot A are
proposed with R6 zoning.
Phase two (Lot 2) incorporates the east half of the subdivision. No
development is proposed on Lot 2 at this time. Lot 2 is proposed with DR
zoning along with the MCC-Major Commercial Corridor Overlay District.
Public
Improvements:
Traffic and Circulation: Grant a noise attenuation easement 115 feet from
the centerline of 180th Street, and show the standard easement language
on the plat.
Place a note on the plat that there shall be no direct access to 180th
Street from any lots.
Provide a reimbursement for prior 180th Street improvements.
Provide for the widening of 180th Street to three lanes along the
subdivision’s frontage.
Review the Right of Way dedication along 180th Street. The existing right
of way is incorrectly shown. ROW must be dedicated for 180th Street, 75
feet from the centerline.
Coordinate with the Planning and Public Works Departments on the
Complete Streets Design Guide Design Checklists.
Proposed site grades along the boundaries of the platting, adjacent to
180th 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 180th Street
improvements. Certification of the grade coordination will be required
prior to the City of Omaha’s approval of the final plat.
Temporary turn-arounds must be provided at the terminus of all
temporarily dead-ended streets.
If Purple Martin Hill 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: 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 for review that relate to the
handling of roadway and site drainage along the development boundary
adjacent to 180th Street.
Sidewalks: Construct sidewalks along all street frontages, including the
subdivision’s 180th Street frontage.
Utilities: Any grading, sewer or utility work carried out in conjunction with this
development, in 180th Street right-of-ways, will require a permit(s) from
the Douglas County Engineer.
Transmission lines exist on the south side of the development and within
180th Street right-of-way adjacent to this site; the applicant must
coordinate with OPPD regarding the layout of the proposed development.
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 project must comply with all stormwater management policies and
ordinances, including providing for a no net increase in stormwater runoff.
and treating the first ½” of stormwater for water quality.
Parks and
Open Space:
Parks: Coordinate the design and construction of park P46 with adjacent
SIDs and the Omaha Parks Department park planning staff. The park
design shall meet the requirements as outlined in the Suburban Park
Master Plan, 2016 Update. The park must be designed by a Professional
Landscape Architect licensed in the State of Nebraska.
Six foot wide sidewalk and street trees will need to be installed on the
north side of Purple Martin Parkway. Final construction plans for these
improvements will need to be submitted to the Parks Department for
review and approval.
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 park.
Outlots: Provide for the use, ownership, and maintenance of the outlot in
the subdivision agreement.
Environmental: Noxious Weeds: The applicant has submitted an acceptable letter of
approval from Douglas County for a Noxious Weed Plan.
Tree canopy analysis and mitigation plan are satisfactory. Ten (10)
mitigation trees will be planted in the common area of the multifamily
buildings. No wetlands are present on the site.
Emergency
Management:
The applicant has submitted a letter stating that installation of a new
outdoor warning siren is required with this development. The applicant
PURPLE MARTIN HILL
Case No.C10-22-182, C10-22-183, C12-22-184

PJB
must coordinate with the Douglas County Emergency Management
Agency regarding the installation of the required outdoor warning system.
Financing: No financing information was provided. Submit a source and use of funds
if the subdivision will be located within an SID or indicate that the
development will be privately funded.
Land Use and
Planning:
Future Land Use: The subject site is designated for low-density residential
development in the Future Land Use element of the Omaha 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 lot is 4.595 acres, which would limit the number of possible
units on this lot to 100, per the allowed density in the R6 district. Outlot A
is also proposed with R6 zoning. However, the intention of this R6 zoning
is to allow for the proposed driveway connection to cross through the
outlot to the multi-family development and will not result in any additional
units beyond the 100 allowed on Lot 1 (off-street parking facilities for multi-
family may only be located on an adjacent site in the same or a more
intensive zoning district). The proposed R6 zoning is appropriate.
The proposed DR zoning is in keeping with the low-density residential
designation of the Omaha Master Plan for the subject site. Further, one of
the intentions of the DR development reserve district is to provide a
transitional zone for the orderly conversion of land from agricultural and
rural to urban uses. Given the unknown development plans for Lot 2, the
proposed DR zoning is appropriate.
180th Street is designated as a Major Commercial Corridor in the Omaha
Master Plan. The requested MCC-Overlay for Lot 2 is appropriate. Future
development on Lot 2 must comply with the MCC overlay. A detailed
code compliance review will take place with the submittal of a building
permit.
Site Plan: While a full zoning review of the submitted development plan
was not completed as part of this request, it was noted that the provided
parking does not appear to comply with the proposed unit count per
Section 55-734. - Schedule of off-street parking requirements. The
applicant has previously indicated the desire to provide less off-street
parking than what the zoning regulations would normally require for this
use due to the fact that a larger number of their clients do not drive, but
are served by van and bus service to and from destinations. Any reduction
to the required number of parking stalls must be approved by the Zoning
Board of Appeals.
III. ANALYSIS:
Conditionally, the proposed subdivision and rezoning is consistent with and carries out the
goals and objectives of the City of Omaha Master Plan.
