SUMMARY
Applicant: CalAtlantic Group, Inc.
Comp. Guide Plan Designation: LDR – Low Density Residential
Current Zoning: R-1, Low Density Residential with the Greystone Planned Unit
Development (R-1: PUD)
Gross Area: 19.1551 Acres
Net Area: 19.1551 Acres
Lots/Units: 43 Single Family Lots
Gross Density: 2.2 units/acre
Net (Met Council) Density: 2.2 units/acre
The applicant, CalAtlantic Group, requests approval of a final plat for Greystone 6th Addition to allow
development of 43 single family lots. The final plat is necessary to facilitate subdivision of the subject
property into individual residential lots, outlots, and public streets. This phase provides for the connection
into the new neighborhood from Bonaire Path, addressing previous concerns about new resident and
construction traffic circulating through the existing Greystone community. Staff finds the application
2
consistent with the Greystone III preliminary plat and recommends approval of the request subject to
conditions detailed in the motion above.
BACKGROUND
In October, 2016, the City Council approved a preliminary plat, Planned Unit Development (PUD) master
development plan with rezoning, and zoning ordinance amendment for the 169 single-family-lot
Greystone III development. At that time, the Council also approved a 22-lot final plat for the first phase
of the Greystone III development. One of the issues at that time was the concern about traffic cutting
through the existing Greystone neighborhood to access the new housing development. The current plat
provides for construction of the collector road which intersects with Bonaire Path, alleviating the stated
traffic concerns. The applicant now proposes to begin platting the second phase of Greystone III with 43
additional single family lots to be known as Greystone III 6th Addition. Greystone III is the eastern
continuation of the Greystone neighborhood. The Greystone neighborhood is located east of Akron
Avenue and south of Bonaire Path.
ISSUE ANALYSIS
Legal Authority. The final plat application is Quasi-Judicial because the City has a set of standards and
requirements for reviewing this type of application that is described in detail below. Generally, if the final
plat meets the ordinance requirements it must be approved.
Land Use and Zoning. The proposed 43 single-family lot subdivision is consistent with the current land
use and zoning classifications. The subject property is guided LDR – Low Density Residential and zoned R-
1PUD, Low Density Residential Planned Unit Development. As a result, the property is subject to all the
standards of the R-1, Low Density Residential zoning districts as well as the standards for detached single
family units contained in the approved PUD. The deviations from the R-1 standards that were part of the
October, 2016, PUD approval include the allowance of two car garage designs; reduction in the minimum
lot size from 10,000 square feet to 8,600 square feet; reduction in the minimum lot width from 80 feet to 60
feet, reduction in the front yard setback from 30 feet to 25 feet; reduction in the side yard setback from 10
feet to 7.5 feet; and the increase of the maximum lot coverage tiered from 30% to 40% depending upon lot
size.

Final Plat. Standards for reviewing subdivision requests are detailed in Title 12 of the Rosemount City
Code. This section of the Code outlines the two-step process for land subdivision. This process includes
approval of the Preliminary Plat and the Final Plat. In this case, the preliminary plat was approved on
October 18, 2016, creating 168 lots for future development. The final plat contains 43 lots for the
construction of single family homes and three outlots to accommodate stormwater infrastructure and
access to the exception parcel located near the northeast corner of the site.
3
Streets and Access. Currently access to the Greystone III development is provided through the eastern
extension of 138th Street through the existing Greystone neighborhood. This plat will create the right-of-
way for installation of the collector road that intersects with Bonaire Path, providing another public route.
In fact, the applicant is required as part of the PUD agreement to construct the road entrance from
Bonaire Path with this phase of development. They anticipate that road construction in mid-2017, with
completion by the end of 2017. The applicant has also committed that much of the heavy equipment
traffic, for grading and utility work, will not go through the existing neighborhood and will gain site access
from the north.
Landscaping and Berming. The landscape plan is consistent with the minimum number of plantings
required by City Code (one per interior lot and two per corner lot). The plan includes 62 boulevard trees.
An additional 38 buffer trees are indicated around infiltration basins and atop the berm that is intended to
provide screening from the railroad track along the northern boundary of the site. The landscape plan also
indicates shrubbery to be planted with the buffer trees.
The landscaping plan indicates a seed mix for the upland areas that includes many wildflowers in addition
to grasses. A condition of approval of the preliminary plat was that the applicant shall update the
landscaping plan to include a seed mix for the infiltration basins that offers a greater percentage of flowers
due to the fact that the soils within Rosemount are sandy and water is not often retained in the basins.
The landscape plan provided has not been updated to account for that condition. A condition of approval
is included that requires the landscape plan to be updated with a seed mix for the infiltration basins that
provides a greater number of wildflowers.
Parks and Open Space. The Greystone 6th Addition creates 43 buildable lots with the remaining land
platted as outlots. The Parks Commission did not request additional land dedication as part of the
preliminary plat and therefore cash payment in lieu of dedication is required. Based upon the current fee
schedule the applicant is required to pay $146,200 (43 units x $3,400 per unit).
Engineering Comments. The City’s project engineer has provided comments in the attached
memorandum dated February 28, 2017. Agreements between the holders of easements for
transmission facilities within the site and the developer are required. The project engineer also
requests updates to the stormwater modeling. Finally, future discussions are necessary to develop a
plan for servicing the exception property located near the northeast corner of the site with water and
sewer.
CONCLUSION AND RECOMMENDATION
Staff recommends approval of the Final Plat for Greystone III 6th Addition creating 43 single family lots.
This recommendation is based on the information submitted by the applicant, findings made in this
report, and the conditions detailed in the attached memorandums.
