EXHIBIT "A"
FINDINGS —APPROVAL (PA -10-10)
A. The proposed project complies with Costa Mesa Municipal Code Section 13-29(e)
because:
1. The proposed use is compatible and harmonious with uses on surrounding .
properties.
2Safety and compatibility of the design of the parking areas, landscaping,
luminaries, and other site features including functional aspects of the site
development such as automobile and pedestrian circulation have been
considered.
3. The project, as conditioned, is consistent with the General Plan.
4. The planning application is for a project -specific case and does not establish a
precedent for future development.
B. The information presented substantially complies with Costa Mesa Municipal Code
Section 13-29(g)(5) in that the proposed development of the 224 -unit senior
housing project meets the broader goals of the General Plan, and the Zoning Code
by exhibiting excellence in design, site planning, integration of uses and structures
and protection of the integrity of neighboring development. The project also meets
the maximum density standards allowed pursuant to General Plan and density
bonus provisions of the Zoning Code Chapter IX. Section 13-152 to provide
housing to seniors.
This design review includes site planning, building . design landscaping,
appearance, mass and scale of structures, roof forms and any other applicable
design features. The buildings are designed with a consistent design integrating
elements of the Spanish Colonial design and articulation on all four sides of the
buildings especially facing Harbor Blvd. and Mesa Verde Drive E. The project
provides substantial landscaping and accent trees to enhance landscaping along
public rights-of-way.
C. The proposed variance to identify private outdoor patios/balconies as exempt from
the City's Noise Ordinance from the exterior noise standards will not allow a use,
density, or intensity which is not in accordance with the. general plan designation
and the zoning code. The requested deviation will be subject to such conditions as
will assure that the deviation authorized shall not constitute a grant of special
privileges inconsistent with the limitation upon other properties in the vicinity and
zone in which the property is located. Specifically, the patio walls and balconies
will be designed with solid stucco walls and wrought iron accents providing privacy
and partial sound attenuation without the maintenance and aesthetic impacts of a
- glass railing. In addition, installation of five-foot glass balcony railings will take away
from the openness and usability of the balconies.
D. An Initial Study/Mitigated Negative Declaration was prepared and circulated for
public review in accordance with the requirements of the California Environmental
Quality Act (CEQA), the State CEQA Guidelines, the Council on Environmental
Quality Regulations implementing the National Environmental Policy Act, and the
City of Costa Mesa Environmental Guidelines.
E. The project is exempt from Chapter IX, Article 11, Transportation System
Management, of Title 13 of the Costa Mesa Municipal Code.
