TO THE COVE COMMUNITIES PUBLIC SAFETY COMMISSION: Indian Wells

ATTENTION: City Managers
SUBJECT: Height Limitation for New Construction in the Cove Communities
ISSUE:
Determine and recommend maximum height of buildings to be constructed in
the Cove Communities. The recommendation is based on present and future
staffing levels, equipment/apparatus and construction standards of all
future buildings.
BACKGROUND:
Historically, the Cove Communities have evolved since incorporation from
County standards for construction to amended standards in fire and building
codes that include built-in fire protection systems limiting the risks and
exposures in major fire situations.
The first multistory buildings in the Coves primarily used type of con-
struction as the fire protection system in conjunction with compartmentation
to limit the fire risk. Present minimum multistory building construction
standards include automatic fire sprinkler systems, ventilation smoke
control systems, standpipe systems and fire alarms for built-in fire
protection. The system requirements vary due to the type of occupancy
within the building. As a minimum, automatic fire sprinklers are required
in all buildings that exceed 5,000-8,000 square feet, and standpipes are
required above the third floor of any building.
The Cove Communities Public Safety Commission has asked for a recommendation
and has passed a resolution for each city to consider, limiting the height
of buildings to eighty feet. The Commission recognizes the limitations of
current staffing levels for fire suppression operations and recognizes the
present and near future planned equipment and apparatus available for fire
operations or incidents within the cities.
The water distribution and fire hydrant systems exceed minimum standards
in all existing multistoried areas and will continue to be required prior
to construction of future multistory buildings.
-2-
Intermediate Case: One significant built-in fire protection system
fails, resulting in horizontal or vertical fire extension
into two or more rooms on one or two stories. Smoke
spreads throughout fire floors.
Worst Case: Two or more built-in fire protection systems fail,
resulting in horizontal and vertical fire extension
into several rooms and floors. Heavy smoke spreads
throughout several floors.
The likelihood of a best case scenario is excellent due to the built-in
fire protection standards and proposed height limitation now under
consideration.
The likelihood of an intermediate case scenario is only probable if
aggressive fire inspections and building occupant information and education
are not routinely implemented. The commitment by the Fire Department and
the Commission to provide these inspections and information and education
is our current philosophy, and we are attempting to accomplish all of our
goals in this area.
The worst case scenario may be an unacceptable level of risk and may be
probable only by a change in philosophy and procedures of the Commission
and the Department.

ACTION REQUIRED:
Review Commission resolution to each City Council for consideration and
adoption based upon this recommendation.

BUILDING SYSTEMS INFORMATION
1. Detection system detects smoke, heat and/or fire in buildings
through other systems or fire alarms to report the fires to the
Fire Department and building occupants.
2. Sprinkler and standpipe systems provide automatic fire sprinkler
coverage in all areas within a building and Fire Department hose
line connections on all floors for the attack of fires. The system
also provides water flow alarms.
3. Ventilation and smoke control systems. Approved automatic air
handling ventilation and exhaust systems remove smoke and toxic
gasses inside a building and confine smoke to the fire area by
positive and negative pressure factors; provide safe egress through
stairwells and hallways for evacuation; remove heated and flammable
gasses to allow Fire Department ingress for operational needs.
4. Compartmentation limits fire spread both vertically and horizontally
by type of construction and requires fire doors and openings to be
protected by two or four-hour standards.
5. Ingress and egress systems provide orderly evacuation for building
occupants and provide ingress for Fire Department operations.
6. Approved elevator systems provide Fire Department access to the
floor below the fire to move personnel and equipment and directs
building occupants to stairwells for protected egress to safe areas.
7. Communication and control systems provide control of fire protection
systems within the building; provide communications for Fire Depart-
ment operations and occupant notification for emergency procedures in
egressing the building.
8. Fire brigade onsite trained personnel. Trained and equipped onsite
personnel can augment Fire Department operations to handle evacuations,
fire confinement and assist in systems control and provide consistent
owner inspections for the maintenance of all the systems within a
building. They can provide information and education to the occupants
of the building for fire safety.
TYPICAL SCENARIO: Fire in one room on 4th floor.
Best Case: All systems work as designed. Smoke detector activates
alarm panel and sprinkler head activates shortly there-
after, activating waterflow alarm. Security immediately
notifies fire department; fire spread is contained by
sprinkler until fire department arrives. Ventilation
system contains smoke to immediate area.

We are currently staffing five engine companies with two to three persons,
one three-person truck company and three two-person medic fire fighter units
in the Coves Cities.
DISCUSSION:
As the Cities approach build out, and land becomes less available and more
costly, the natural pressure will be to build structures higher. The maximum
height limitation will limit square footage available for commercial revenues
for the Cities' general funds. On the other hand, the fiscal impact will
also be capped on future fire department personnel and equipment costs.
In other areas of Southern California, other fire protection agencies have
established rules of thumb, where buildings exceed eight stories, minimum
staffing requirements for incidents require 100 fire personnel or more to
be on scene within ten minutes. This rule of thumb is based upon minimum
fire and building code standards that do not meet the higher fire protection
standards in the Coves.
1
The inside and outside access to buildings is expected to be limited by the
apparatus in service and fire personnel for the total emergency operation.
A 100 foot aerial platform will access 80-90 feet floor level in buildings.
ALTERNATIVES:
L. Limit building height to eighty feet at the highest level of
approved Fire Department access, which is the floor level or
parapet level of any future building.
2. Limit the height of future buildings to eight stories with a
maximum of ten feet per story and provide approved Fire Department
access at no more than five feet above the floor level of the
eighth story.
3. Continue to review each building submitted for approval in the
development plan/precise plan process under the current thirty
foot height limitation in each city and address the height
limitation issue on a case by case basis.
4. Coves-wide eighty foot height limitation and review the impact
at five-year intervals to assess the direction of the Commission
based on the demands at that five-year interval.
RECOMMENDATION:
Alternative No. 1, to limit building height to eighty feet at the
highest level of approved Fire Department access, is recommended.
