(Ord. 1070 § 1; Ord. 2149 § 1, 2005)
(a) Doors—Self-locking devices. Exterior doors and doors leading from garage areas into multiple-family dwellings, and doors leading into the stairwells of such dwellings, shall have self-locking (deadlatch) devices, allowing egress from the building or into the garage area, or stairwell, but requiring a key (keypad or keycard) to be used to gain access to the interior of the building from the outside or garage area or into hallways from the stairwell.

Property owners, any designated agent, tenant, and the general
contractor for the project in question shall be jointly and severally
responsible for compliance with this article. Security items that

(1) Parking lots with ten or more parking spaces (including parking lots
with carports), driveways, circulation areas, pathways, passageways,
recesses, and grounds contiguous to buildings shall be provided with
sufficient illumination to make clearly visible the presence of any

architectural review approvals that may be required by the city, the
police department shall approve all ATMs and location placements.
Because of the variety of ATMs and the unique characteristics of each
installation and crime considerations near each respective ATM, there
is no one formula for placement of the ATMs. Each planned placement
shall be studied for safety features and environment around each machine.
The police department may place hour restrictions depending on location
and may require some modifications as to structure, location, and
hours of servicing. Surveillance cameras or video transactions may
be required by the police department. The police department may deny
the location because of safety issues. ATMs placed within a business

approval shall proceed concurrently with the zoning or site plan and
architectural review.
(c) All
approved ATMs shall adhere to the following requirements:
(2) Both an ATM and its customers shall be visible from surrounding businesses,
streets, and pedestrian traffic areas. Hours of ATM operation and

(Ord. 2149 § 1, 2005)
In projects of a more complex nature than the typical residential,
commercial or industrial development, additional security measures,
which are more stringent and site specific than those stated elsewhere
in this article, may be required by the community development and
sustainability department, fire department, police department, planning
commission, or city council as conditions of approval of a use permit,
zoning, or other land use entitlement. Such additional security measures
may be made based on the fact that the project is of a highly complicated
nature or, by its location, may significantly and adversely affect
the city's ability to respond to security and/or other emergency situations
within the project.
(a) Such
additional requirements shall be determined by considering the specific
individual characteristics of a project and the needs dictated by
such characteristics. Security measures required under this section
may include, but shall not be limited to:
(2) Video monitoring and recording systems;
(4) Site circulation, parking and lighting systems;
(5) Detailed documented integrated security plans;
(6) Consultant services, paid for by the developer, as needed for detailed
plan review and systems testing; and

measures required under this section as a condition to a project may

to use. Further, other sound methods of structural design or analysis
not specifically provided for in this article may be allowed provided
such alternative has been approved by the enforcing authority prior
to use. The enforcing authority may approve any such alternate provided
that it finds the proposed design to be satisfactory and the material
and method of work offered is for the purpose intended, at least equivalent
to that prescribed in this article in quality, strength, effectiveness,
crime resistance, durability and safety.
(Ord. 2149 § 1, 2005)
The enforcing authority may require tests as proof of compliance

and methods of construction and to provide for reasonable interpretations
of the provisions of this article, the city manager shall hear all
disputes. The city manager shall issue written findings and conclusions
