Dear Mayor and City Council Members:
The City of Dubuque Zoning Advisory Commission has reviewed the above -cited
request. The application, staff report and related materials are attached for your review.
Discussion
The applicant spoke in favor of the request, reviewing the location of the property off
Humke Road, number of lots, a private street, and that storm water management
techniques include narrower streets and rain gardens.
Staff reviewed the staff report, noting that the subject property is outside the City's
Fringe Area Policy area but within two -miles of the City's corporate limits, and is jointly
being reviewed with the County. Staff reviewed the layout of the subdivision and that
the new intersection with Humke Road will meet site distance standards. Staff reviewed
that the submitted preliminary plat complies with the 40 points of sustainability and that
sufficient easements are provided for future extension of City water and sanitary sewer.
There were no public comments.
The Zoning Advisory Commission discussed the request, and felt that the submitted
subdivision was consistent with the Unified Development Code.
Recommendation
By a vote of 3 to 0, with one abstention, the Zoning Advisory Commission recommends
that the City Council approve /deny the request, subject to waiving lot frontage for Lot 5
and allowing a 22 -foot wide private street.

Physical Characteristics: The subject property is on the north side of Humke Road
approximately'% mile east of Sundown Road. The subject property will be served by
private street to be called Katra Court with direct access onto Humke Road. The
topography is rolling and generally drains to the northeast.
Proposed Phasing: None.
Previous Conditions of Zoning or Plats: None.
Dedication of Open Space or Public Amenities: None.
Proposed Streets and Grades: Katra Court — 1.5 to 10.5% grade.
Recommended Motion: Motion to approve the submitted preliminary plat of Katra
Subdivision subject to waiving street width standards for Katra Court and waiving lot
frontage requirement for Lot 5. The submitted preliminary plat is in other respects
compliant with the Unified Development Code.
Subdivision Staff Report — Katra Subdivision Page 2
Conformance with Comprehensive Plan: This subdivision meets the Comprehensive
Plan Land Use Element Goal 1.2, 1.5, 1.8, 4.3, and 10.2.
Impact of Request on:
Utilities: The proposed Katra Subdivision will utilize individual septic systems for
each building lot and will have shared wells within the subdivision for water service.
Traffic Patterns: Access to the proposed subdivision is off of Humke Road. Based
on 2009 IDOT vehicle trip counts there are 410 average daily trips on this portion of
Humke Road.
Public Services: Existing public services are adequate to serve the site.
Environment: Staff does not anticipate any adverse impact to the environment
provided Dubuque County Erosion and Sediment Control and storm water manual
is complied with.
Adjacent Properties: Staff anticipates that the most notable impacts to adjacent
properties will be a change in the visual nature of this property with a change from
open space to residential housing and an increase in vehicle trips on Humke Road.
Staff estimates that with seven new building lots (Lot 8 is currently built on) when
fully built out with single - family homes approximately 67 average daily trips will be
generated.
Recommended Conditions on Plat: None.
Staff Analysis: The submitted Preliminary Plat of Katra Subdivision is located on the
north side of Humke Road approximately'lA mile east of Sundown Road (County Road
Y21) and approximately 2.5 miles west of Seippel Road. The proposed subdivision will
include seven new single - family building lots with an 8th lot already built on. The subject
subdivision is jointly reviewed by both the City and County of Dubuque as it is within two
miles of the City of Dubuque's corporate limits.
The preliminary plat of Katra Subdivision encompasses 13.5 acres. Access to this
proposed subdivision will be from a new private street to be named Katra Court. The
new road will connect with Humke Road. The applicant's engineer has provided
documentation that the proposed intersection will meet the ASHTO standards for site
visibility.
The proposed Katra Court private street will be approximately 500 feet in length. City
Engineering standards establish 1,300 feet as the maximum for cul -de -sac length. The
Subdivision Staff Report — Katra Subdivision Page 3
proposed private street will have 22 -foot of paving within a 66 -foot right -of -way. The
proposed cross - section of the roadway will have a drainage swale on the west side of
the roadway only. The cul -de -sac will be built with a 75 -foot radius.
The submitted Preliminary Plat of Katra Subdivision includes one single - family building
lot with a substandard street frontage, Lot 5. The street frontage at the right -of -way
easement line is only 27 -foot, where the City standard is a 50 -foot street frontage.
Planning staff does not object to this proposed layout given the size and layout of the
subject lot.
There is an existing 50 -foot pipeline easement for British Petroleum (BP) that runs
through the proposed subdivision. The developer has met with BP officials, and has
laid out the subdivision lot lines in a way that complies with the guidelines established
by BP. Primarily, BP officials do not desire to have lot lines going down the centerline
of a pipeline easement as this then places any lot line fence or plantings directly over
the pipeline itself. By keeping lot lines to one side or the other of the easement line,
this will then eliminate this issue from occurring.
The Planning Services Department has reviewed the proposed Preliminary Plat for
compliance with the City's sustainability requirements. The submitted Preliminary Plat
of Katra Subdivision proposing the following sustainable subdivision development tools.
1) 22 -foot wide private street built to County standards — 5 points.
2) The covenants for the subdivision will require a minimum tree planting on
each lot — 5 points.
3) The proposed Katra Court street will be built as concrete (reducing heat
island effect) — 5 points.
4) French drain /soakaway pit used for handling storm water from private
street — 5 points.
5) The proposed subdivision falls under Dubuque County's erosion and
sediment control and stormwater management manual. This manual
incorporates storm water management, sediment and erosion control,
sediment and erosion control, and post construction requirements under
one document that in some ways exceeds City requirements. 20 points.
TOTAL: 40 points
Planning staff is willing to allow the 20 points for compliance with the County Ordinance
on a conditional basis. The submitted Final Plat and Improvement Plans will need to
specifically address Best Management Practices (BMP) that will warrant 20 points. The
County Ordinance requires that the first 1.25 inches of rain be infiltrated on -site. This
requirement is more stringent than City requirements. At this time, the developer is
Subdivision Staff Report — Katra Subdivision Page 4
contemplating utilizing rain gardens for each new building lot. Under the Unified
Development Code, this would net the developer 10 points.
The proposed subdivision is located outside the area included in the City's Fringe Area
Policy. The subject property was outside the two -mile boundary included in that policy
when adopted. A copy of the map for the Fringe Area Policy is attached to this staff
report. The large annexation along Middle Road in 2008 brought this area within two
miles of the City. The subject property, if it was included in the Fringe Area Policy
document, would have been considered a secondary growth area.
The submitted Preliminary Plat is in substantial compliance with the secondary growth
area subdivision review standards even though it is not subject to the Policy. The
proposed private street, Katra Court, rather than being built to a 26 -foot wide county
street standard, is a 22 -foot wide roadway. The proposed subdivision will utilize shared
wells; however, individual septic fields will be constructed for each lot rather than a
centralized system. The submitted Preliminary Plat does provide sufficient easements
for the future extension of City water and sewer to serve this subdivision. This ensures
that the City will not need to acquire individual easements from future property owners.
Planning staff recommends the Zoning Advisory Commission approve the submitted
Preliminary Plat of Katra Subdivision subject to waiving street width standard for Katra
Court and waiving lot frontage requirement for Lot 5.
