DETAILS:
SUMMARY: The applicant Blake Architects, representing the owner Cambium Capital, LLC, is
seeking approval of a zoning change and site plan to revise the approved building
elevations of five (5) office buildings. The current zoning is "S-P-1" Detailed Site
Plan District with "0-1 "Office District Uses. Any major elevation revisions or
changes to the buildings zoned under "S-P-1" Detailed Site Plan District require
approval of the zoning change by City Council. The elevations of the proposed
buildings have changed to an updated fagade design to reflect current trends.
Materials have changed from brick and stone to painted brick(light color or white in
color). The building elevation exhibits are presented in Attachment C, pages 7-12.
The applicant is requesting that all previously approved regulations, variances and
stipulations as approved with the previous zoning approval (ZA 07-139) remain in
effect. This includes the following:
Regulations
"S-P-1" Detailed Site Plan District with "O-1"Office District uses and development
regulations with the following exceptions:
1. Portions of bufferyards along interior lot lines shall not be required as
shown on the site plan.
2. The future buildings shall be similar in design and construction and shall
match the exterior elevations, roof height, style and design, building
materials and exterior color of the building to be constructed on Lot 1 R2.
3. All building setback lines and site improvements shall be as depicted on the
site plan.
Case No.
ZA15-093
The applicant has restated these conditions in a letter dated October 16, 2015 and
attached on Attachment C, p. 5.
Variances
A driveway stacking variance was approved to allow a 47-foot stacking depth where
a 50-foot stacking depth was required on Silicon Drive.
Conditions of Approval from Previous Zoning Case ZA 07-139
1. Accepting the applicant's agreement to meet the City's ordinance
requirements for fencing at the time of construction of Lot#2.
2. Accepting the applicant's agreement that all three monument signs are the
same.
Tree Preservation Plan
At the November 3, 2015 City Council meeting, the applicant had indicated there was
65% tree coverage on this site (this calculation includes trees located in the right-of-
way) and had indicated 40% of the existing cover is to remain (this included
approximately 10% of the trees located within the right-of-way). The Landscape
Administrator had determined that the actual applicable tree cover preservation was
approximately 30%. The applicant had included a regulation to the development
regulations to allow the tree preservation as shown.
For the November 17, 2015 City Council meeting the applicant will preserve the
protected and marginal trees and will meet the 40% tree preservation. The tree
preservation plan is shown on Attachment C, page13. Staff has provided an analysis
of the plan in the tree preservation section of the staff report located on Attachment
A, p. 2.
Summary of Building/Elevation Changes
Each of the five buildings will be reduced slightly in the floor area from the originally
approved site plan. In the previously approved planning case ZA07-139, the five
buildings totaled 29, 970 square feet. For this request, the five buildings will be
reduced to a total of 28,773 square feet. In the previously approved zoning change
and site plan (ZA07-139), only the Lot 1 building elevation was approved by City
Council (See Attachment C, p. 2). The applicant has revised the building elevations
to include two entrances on Building #1 and #2 instead of the one entrance as
approved in planning case ZA07-139. The applicant proposing a change in materials
from brick and stone (ZA07-139) to painted brick (light color or white in color).

TREE PRESERVATION: The requested "S-P-1"zoning district does not require the applicant to preserve
any minimum amount of trees, but rather makes the tree preservation plan

require 40% preservation of the existing trees (65%) on the site.
At the November 3, 2015 City Council meeting, the applicant indicated there
was 65% tree coverage on this site (this calculation includes trees located in
the right-of-way) and has indicated 40% of the existing cover is to remain (this
includes approximately 10% of the trees located within the right-of-way). The
Landscape Administrator has determined that the actual applicable tree cover
preservation is approximately 30%. The applicant had included a regulation to
the development regulations to allow the tree preservation as shown.
Case No. Attachment A
ZA 15-093 Page 2
For the November 17, 2015 City Council meeting the applicant will preserve the
protected and marginal trees and will meet the 40% tree preservation.
The sanitary sewer utility installation along Crooked Lane right-of-way and the
lots may impact the existing trees. The Landscape Administrator has noted that
both the utilities and grading are to be limited in altering the critical root zone
areas of the existing trees proposed to be preserved.
UTILITIES: A 12-inch water line currently exists along the east side of S. Kimball Avenue.
An 8-inch sanitary sewer line currently exists along the west side of S. Kimball
Avenue.

TREE CONSERVATION COMMENTS:
* The proposed existing tree cover preservation complies with the Existing Tree Cover Preservation
Requirements of the Tree Preservation Ordinance 585-D. There is 65% existing tree cover on the site
and 40% of the existing tree cover is required to be preserved. 40% is proposed to be preserved
which includes both "Protected" (green) trees and "Borderline" (yellow) trees.
* Tree Conservation Plan shall be approved if it will preserve existing tree cover in accordance with the
percentage requirements established by Table 2.0.
Table 2.0 — Existing Tree Cover Preservation Requirements
Percentage of existing tree cover on Minimum percentage of the
the entire site existing tree cover to be
preserved*
0% - 20% 70%
20.1 —40% 60%
40.1% - 60% 50%
60.1% - 80% 40%
80.1% - 100% 30%
*The minimum percentage of existing tree cover to be preserved shall exclude any area in public
rights-of-way as approved by City Council.
For property sought to be zoned for the Downtown zoning district or a planned development zoning
district, including an S-P-1 Site Plan, S-P-2 Site Plan, Transition, Rural Conservation, Planned Unit
Development, or Employment Center zoning district, the City Council shall consider the application for
a Conservation Analysis or Plan in conjunction with the corresponding development application (as
established in Table 1.0). The Planning and Zoning Commission shall review the application and
make a recommendation to the City Council regarding the application. The City Council shall approve
the Plan or Analysis if the Council finds that the Plan or Analysis provides for the:
i. placement of building pads, parking areas, driveways, streets, and utility easements so as to
maximize the preservation of environmental features of the property including mature tree
stands, natural creeks and ponds, and significant grades;
ii. maximizes the preservation of tree cover preservation areas indicated on the Environmental
Resource Protection Map;
iii. maximizes the preservation of existing tree stands with the potential to buffer residential areas
from the noise, glare, and visual effects of nonresidential uses;
iv. maximizes the preservation of existing trees, if any, adjoining a natural or man-made drainage
creek;
V. maximizes the preservation of existing protected trees along rural roadways and other streets
as identified and prioritized in the Street Typology designation; and
