Subject/Title: Adopt a resolution approving a Tentative Parcel Map (MS
361-06) to subdivide approximately 3 acres into 4 single-family residential
lots, including making the necessary findings for an exception to the City’s
Density Transition Policy allowing one residential lot less than 20,000 sq.
ft. to abut an existing residential parcel larger than one acre for the

Adopt a resolution approving the tentative parcel map for the Hanberg
Property, located at 1941 Grant Street and making the necessary findings
regarding an exception to the City’s Density Transition Policy.
The Planning Commission recommended approval of Tentative Parcel Map No.
361-06 and the exception to the Density Transition Policy allowing one
residential lot (Parcel “B”) less than 20,000 sq. ft. to abut an existing
residential parcel (Bonnano Property) larger than one acre.
The City Council, on October 24, 2006, approved an amendment to Plan
Development (PD) No. 26 (RZ 06-12) establishing development standards for
Planning Area 6 of PD-26.
At the May 15, 2007, Planning Commission meeting, the Commission unanimously
voted to recommend approval of Tentative Parcel Map No. 361-06 for the
subdivision of approximately 3 acres into 4 single-family residential lots
and an exception to the Density Transition Policy to allow a residential lot
less than 20,000 sq. ft. to abut an existing residential lot larger than
one-acre. The policy requires that any exceptions and the corresponding map
be approved by the City Council.
The proposed parcel map would subdivide an existing 3-acre parcel currently
developed with a single-family dwelling into four separate parcels as
Parcel “A” – 15,074 sq. ft.
Parcel “B” – 14,699 sq. ft.
Parcel “C” – 42,491 sq. ft.
Parcel “D” – 38,427 sq. ft.
General Plan Consistency
The General Plan designation for this property is Low Density Residential
(1.1 to 5.0 du/ac, with a midrange of 3 du/ac). This property is 3-acres in
size and based upon the allowable General Plan density the site could have
anywhere from 3 dwelling units up to 15 dwelling units with a midrange
density of 9 dwelling units. The proposed plan will subdivide the 3-acre
site into four smaller parcels for future residential development creating
an overall density of 1.33 dwelling units per acre, consistent with the
General Plan and well below the midrange density of 3 dwelling units per
This parcel is zoned Planning Area 6 of Planned Development No. 26. The
minimum lot size for this zoning designation is 12,000 sq. ft. for
single-family residential units. As stated above, the applicant is proposing
lot sizes of 14,699, 15,074, 38,427, and 42,491 square feet. The minimum lot
width required in Planning Area 6 is 70 feet. The lot widths proposed on
this parcel map range from a minimum of 97 feet to 212 feet. The actual and
required setbacks for the existing house and the future three single-family
units are as follows:
Required Existing House
Minimum front yard setback 25 feet 105 feet
Minimum side yard setback 10 feet 50 and 105 feet
Minimum rear yard setback 30 feet 31.5 feet
Building height 35 feet/2 story 21 feet/single story
Therefore, the proposed lots and existing residential unit would continue to
be in conformance with the zoning for the property.
The project requires compliance with the City’s density transition policy as
outlined in the General Plan, which requires proposed lots facing or
abutting existing residential lots of one acre or more to have a minimum
area of 20,000 square feet. The policy requires that the map be reviewed and
approved by the City Council. In addition, the policy allows exceptions to
the required lot size, under certain circumstances and after the adoption of
specified findings. One of these circumstances is that the adjacent property
has a land use and/or zoning designation that would enable the future
subdivision of said property into lots of a size similar to those planned in
the proposed subdivision.
The only lot in question is Parcel “B”. It is a 14, 699 square foot lot
abutting a 2.28-acre existing parcel (APN 017-010-014) to the east of the
project site. Under the density transition policy this would be allowed
because the adjacent property has a land use and zoning designation that
would enable the future subdivision of the property into lots of a size
smaller (12,000 sq. ft. vs. 14,699 sq. ft.) than those being planned in the
Staff has not received any correspondence from the adjacent owner objecting
to the proposed lot size. It should be noted that the affected property
owner has been notified of the project as a result of the City’s public
hearing notice process. Staff has included a finding in the attached
resolution addressing the density transition issue.
The applicant will be required to pay all relevant fees as specified in the
conditions of approval for Tentative Parcel Map No. 361-06. The project,
once developed, would generate additional property tax for the City of
Brentwood. The project would also increase demand for the urban services the
City provides, which will result in ongoing service delivery costs
associated with this project.

to the density transition policy.
CITY COUNCIL RESOLUTION NO.

WHEREAS, Rob and Maryann Hanberg have requested that the City approve
Tentative Parcel Map No. 361-06 to allow the subdivision of approximately 3
acres into 4 single-family residential lots and make the necessary findings

than one acre; and
WHEREAS, said tentative parcel map was referred to various public utility

WHEREAS, a Notice of Public Hearing was distributed to all property owners
of record within 300 feet of the project site and published in the Brentwood

Section 65090; and
WHEREAS, the Planning Commission of the City of Brentwood held a public
hearing on this project at its regular meeting of May 15, 2007, and passed
Resolution No. 07-036 recommending that the City Council approve Tentative
Parcel Map No. 361-06; and
WHEREAS, the City Council has considered the staff report, supporting
documents, public testimony, and all appropriate information that has been
submitted with the proposed project; and
NOW, THEREFORE, BE IT RESOLVED that the City Council of the City of
A. Hereby finds that:
1. The proposed tentative parcel map is in conformance with the City’s
General Plan and Zoning Ordinance because all of the proposed lots exceed
the minimum lot size of 12,000 square feet as required by the Planned
Development No. 26 Planning Area 6 Zoning and the overall unit density is at
1.33 units per acre, below the Low (L) General Plan Designation midrange
density of three units per acre; and
2. The discharge of waste from the proposed subdivision will not result in
violation of existing requirements prescribed by the California Regional
Water Quality Control Board because the applicant will be required to make
the necessary improvements to tie in to the City’s stormwater and sewer
3. The site is physically suitable for the type and the density of
development proposed because it does meet the General Plan and Zoning
designations development requirements; and
4. The design of the subdivision is not likely to cause serious public
health problems due to the fact that this project will be required to
construct all of the necessary improvements needed to ensure a safe and
healthy development; and
5. Since the adjacent property designated as the Bonnano Property (APN
017-010-014) is zoned Planning Area 6 of Planned Development No. 26 for
single family residential development and could be subdivided into lots
having a minimum size of 12,000 sq. ft. and no correspondence has been
received from the owner of said property objecting to the lot sizes
associated with the proposed subdivision, the intent of the Density
Transition Policy as outlined in the City General Plan is being adhered to;
6. The project site is not located within the City’s Redevelopment project
7. The design of the subdivision and the type of improvements will not
conflict with easements, acquired by the public at large for access through
or use of, property within the proposed subdivision.
B. Hereby takes the following actions:
1. Approves Tentative Parcel Map No. 361-06, subject to the conditions of
approval listed in Exhibit "A", attached hereto and made a part of this
resolution, and all City standards applicable to this project; and
2. Approves the exception to the density transition policy from the required
minimum 20,000 square foot to 14,699 square feet for Parcel “B”, due to the
fact that the adjacent property designated as the Bonnano Property (APN
017-010-014) is designated and zoned for lot sizes smaller than those in the
This tentative parcel map is valid for two years and will expire on June 12,
2009, unless a final map is recorded prior to that date, or a written
extension is requested by the applicant and approved by the Planning
Commission prior to the expiration date.
