COUNCIL ACTION FORM
SUBJECT: RESOLUTION APPROVING THE REVISED PRELIMINARY PLAT FOR
NORTHRIDGE HEIGHTS SUBDIVISION, INCLUDING APPROXIMATELY 224 ACRES,
GENERALLY LOCATED NORTH OF BLOOMINGTON ROAD, EAST OF GEORGE
WASHINGTON CARVER AVENUE, AND WEST OF THE UNION PACIFIC RAILROAD
RIGHT-OF-WAY.
BACKGROUND:
The history and proposed changes included in the Master Plan report are identical for this
case as well; therefore, these items are not repeated here. As part of the proposed
changes identified in the previous report,the developer is requesting approval of a revised
Preliminary Plat.for the Northridge Heights Subdivision.
ANALYSIS:
Existing Land Use. The 224-acre subject property is currently under cultivation with the
exception of the existing eight-unit apartment building and the area within the first four
additions, which are under construction. Northridge Subdivision, a low density residential
development, and the Taylor Farm are located to the south of the subject property.
Proposed Land Use. The developers are proposing to develop 347 lots with single-family
detached units, 116 lots with single-family attached units, and four lots with 299 apartment
units. There will also be a 4.0-acre park site and three outlots that will have detention
ponds and open space.
Land Use Policy Plan (LUPP). On March 28, 2000, the City Council approved an
amendment to the Land Use Policy Plan (LUPP) that designated this property with a
unique area classification titled "Near Term Land". The intended use for an area
designated "Near Term Land"would be either village residential or suburban residential. In
this case, the developers have chosen to develop this site as a suburban residential
development with a combination of low density residential and medium density residential.
The proposed Preliminary Plat is consistent with the LUPP designation.
Zoning. The current zoning of this property"FS-RL" (Suburban Residential Low Density)
and "FS-RM" (Suburban Residential Medium Density). The proposed revised Preliminary
Plat is consistent with the current zoning.
Utilities. The utilities adjacent to this site will be adequate to serve the needs of this
development. All of the utility information is remaining unchanged from the previously
approved Preliminary Plat.
Water Distribution. There is a 16-inch water main along the north side of
Bloomington Road from the water tower east of the site, to the intersection with
George Washington Carver Avenue. A 12-inch main extends to the west and north
along the north and east sides of George Washington Carver Avenue.
Water mains will be extended into the site on the east and north sides of the street
rights-of-way from the 16-inch water main along the north side of Bloomington
Road. There will be 12-inch water mains along Harrison Road; Wembly Drive;
Beckley Drive; and Stange Road, south of Harrison Drive.All of the rest of the water
mains will be 8-inch mains. The water mains will be extended to the limits of the
subdivision. All costs associated with these water main improvements shall be the
responsibility of the developer.
Sanitary Sewer. There is an existing 15-inch sanitary sewer in Valley View Road,
south of Bloomington Road,which will be extended north into the subdivision.There
will be a 15-inch sanitary sewer main in the center of Valley View Road north to
Burnham Drive; from there it will be extended west and north along the center of
Burnham Drive, Bridgeport Drive, Foxley Drive, and Wembley Drive. This 15-inch
main will then be extended east to Valley View Drive and then north to the northern
limits of the subdivision. All other lots will be served by 8-inch sanitary sewer mains
located in the center of adjacent streets. All costs associated with these sanitary
sewer mains shall be the responsibility of the developer.
Storm Water Management.The storm water management plan will provide storage
for storm water generated by the developed site during a major (100-year) storm
event, which will be provided by four detention ponds. Total outlet flow from the
three ponds in the southwest portion of the site will be limited to the rate discharged
from the pre-developed area contributing to the Squaw Creek watershed during a
minor (5-year) storm event. The outlet flow from the pond along the east border of
the subdivision will be limited to the rate discharged from the pre-developed area
contributing to the Hayden Heritage Park(former Hallett's Quarry)watershed during
a minor(2-year) storm event. Flow from the east pond will leave the site via a new
outlet constructed under the railroad tracks to connect to the storm sewer in the
Bloomington Heights Subdivision.
The developers have also submitted an acceptable storm water pollution prevention
plan for this site.
2
Streets and Vehicular Access. The proposed streets and vehicular access is remaining
largely unchanged from the previously approved Preliminary Plat. Access to the subject
property will be provided from four existing adjacent streets; Bloomington Road, George
Washington Carver Avenue, Valley View Road, and Stange Road. Valley View Road and
Stange Road will be extended to the north through the subdivision, and Harrison Road will
eventually extend through the subdivision from George Washington CarverAvenue to the
Union Pacific Railroad right-of-way.Additional right-of-way for Harrison Road is shown east
of Stange Road to allow for an overpass across the railroad tracks at some future date.
The remainder of the streets within the subdivision will be local streets.
The only modification to the street system occurs in the 3.88-acre area at the northeast
corner of Chilton Avenue and Bloomington Road. The previous plan illustrated one private
street (Farnham Drive), which connected Chilton Avenue on the west to another private
street on the north (Norwich Street).The revised Preliminary Plat also illustrates access to
the proposed lots in this location via private streets (Farnham Drive, Ashton Avenue, and
Burnham Place). However, instead of the private street providing for a connection to the
north,the private streets connect to Chilton Avenue in two locations. Staff believes that this
change is minor and will not affect the overall circulation within this development.
The developers have created a parking prohibition plan for all the streets in the subdivision,
which is included in the General Notes on the Preliminary Plat. Access to individual lots
from George Washington Carver Avenue and Bloomington Road will not be permitted, and
access from Stange Road will be limited to three locations as noted in the General Notes.
Sidewalks will be constructed on both sides of all public streets except where bicycle paths
are shown on the Preliminary Plat. Also, mid-block pedestrian walkway easements are
shown where block lengths exceed 660 feet in length as required by the Suburban
Residential regulations.
Bicycle paths will be provided as follows:
• Along the west side of Stange Road;
• Along the north side of Weston Drive from Stange Road west to George Washington
Carver Avenue;
• Along the north and east sides of George Washington Carver Avenue;
• Along the north side of Harrison Road between Stange Road and Chilton Drive;
• Along the east side of Chilton Drive from Harrison Road to Burnham Drive; and,
• Along the west side of Outlot C, the west and north sides of Outlot B, through the
center of Outlot D, and along the north side of Lot 460.
These bicycle paths will provide access for residents throughout the subdivision and are
consistent with the Bicycle Master Plan.
Fire. The City's response time goal is to have 85% of the land area of the City within a
response time of five (5) minutes or less. The southeast portion of the subject property is
located in an area that meets the five-minute response time. The northwest portion of the
subject property is within an eight(8) minute response time,which would be within that part
of the City that comprises 15% of the area that is outside the City's desired response time.
3
Street Tree Planting Plan. The developer has submitted a street tree-planting plan, as
required by the Subdivision Ordinance for residential subdivisions. A combination of
Norway, Sugar, Black Maple, and White and Green Ash trees are proposed within this
development. These trees will be planted approximately 50 feet on center with adjustment
for driveways and intersection sight distances. All of the proposed trees are on the list of
recommended trees to be planted in the public right-of way.

Master Plan for the Northridge Heights Subdivision to assure that it will be developed
consistent with the intent of the Zoning Ordinance, Subdivision Regulations, and other
adopted plans and policies of the City of Ames.
1. That the conditions and requirements of the previously approved Development
