SUBJECT: CITY COUNCIL RESOLUTION SUPPORTING APPROVAL OF A HELISTOP
ON THE ROOF LEVEL OF THE PARKING STRUCTURE AT SIERRA VISTA HOSPITAL
ARC MI 84-09; 21 CASA STREET).
RECOMMENDATION
Adopt a resolution supporting the Community Development Director's action to approve a
helistop on the roof of Sierra Vista Hospital's parking structure at 21 Casa Street.
DISCUSSION
Situation
Sierra Vista Hospital submitted a planning application for architectural review of a helistop on
the roof level of the parking structure on the Sierra Vista Hospital campus. California Public
Utilities Code Section 21661.5 (b) requires that the City Council or its designated design review
authority approve plans to construct a helistop located within City boundaries.
On November 6, 2009, the Community Development Director approved through a minor or
incidental architectural review application the design of the helistop. With that approval,
findings were made as to the reasons why the requested helistop does not conflict with
surrounding land uses. The applicant, Siena Vista Hospital, has requested that the City Council
approve a resolution acknowledging this previous approval in order for them to continue to
pursue necessary permits from State agencies. The draft resolution (Attachment 5) reiterates the
same findings, conditions, and code requirements that were approved along with the minor or
incidental architectural review (Attachment 4 — November 6, 2009 ARC MI 84-09 approval
letter).
Hospital Master Plan
Over the past few years and after number hearings, Sierra Vista Hospital has had several
Planning entitlements approved to expand the size of its hospital campus and to plan for new
facilities. In 2003, Sierra Vista Hospital received use permit and rezoning approvals to
accommodate a campus master plan which detailed where new buildings and facilities would go.
On May 15, 2006, the ARC approved plans for a large addition to the main hospital known as the
trauma tower and a new parking structure to serve the hospital campus. These plans included a
four-story, approximately 124,500 square-foot hospital tower with basement, a five-level parking
structure with 523 spaces, a service yard, and reconfiguration of the surface parking areas and
circulation plan. Consistent with the approved master plans, a new 45,000 square-foot medical
office building was approved by the ARC on September 4, 2007.

Some of the facilities envisioned by the master plan have been developed such as the parking
structure, others are under construction such as the medical office building, and some, like the
trauma tower, are planned for the future. The proposed helistop is an ancillary component of the
campus and is planned to be installed on the roof level of the existing parking structure.
What is a Helistop?
A helistop is a landing place for helicopters, often on the roof of a building or in some other
limited access area. There are a number of different terms to describe similar facilities including
heliport and helipad. The applicant's supporting documents explains that the term "helistop"
was specifically used in the subject case as it will be a facility where helicopters simply pick up
and drop off patients, rather than house other related activities such as maintenance, refueling
and storage.
Benefits of the Helistop
Helicopter access to hospital facilities is a common and important feature. The quicker critical
patients can get to a hospital, the greater the likelihood they receive life saving treatment. The
helistop will also enhance the neonatal program at the hospital, assist in getting injured and ill
patients out of remote and rugged areas of the County, and provide a needed transport system
when highways are closed during emergencies (Attachment 5).
Helistop Design
The helistop dimensions are 54 feet by 54 feet and will occupy 2,916 square feet of the roof of
the parking structure. Since the helistop will be on a raised platform with approximately 8 feet, 6
inches of clearance, its footprint will not result in the loss of exiting parking spaces However, a
total of 17 parking spaces will be lost to a stairwell and an accessible ramp that provide access
from the platform down to the roof level and elevators beyond. The loss of these spaces does not
result in a deficit for the hospital campus' overall parking requirement. Parking calculations
indicated that even with the loss of these 17 parking,spaces, there will still be a surplus of 64
parking spaces for the overall campus master plan. Finding No. 4 in the recommended
resolution documents the fact that overall parking supplies are not adversely affected by the
project.
Another important consideration with the review of the project is that the project has been
designed to be as inconspicuous as possible by incorporating the following:
a. The elevation of the helistop has been lowered as much as feasible on the parking
structure's roof deck;
b. The beams of the helistop will be painted to match the parking structure; and
c. The helistop will be supported by the beams of the parking structure;
Finding No. 2 in the recommended resolution finds that the proposed design is consistent with
the Community Design Guidelines since the new helistop will blend with the architectural lines
of the existing parking structure

Noise & Lighting Impacts
Potential glare and noise impacts were addressed as part of the minor or incidental architectural
review process and features to minimize these concerns are inherent in the project design.
Condition No. 2 in the recommended resolution calls for photometrics and details to be included
in working drawings for a building permit that confirm that both aesthetic and safety goals are
met by keeping light fixture height as low as possible and illumination levels to a minimum, but
still adequate for hospital operations.
Since the helistop will only be used in emergency situations, noise levels will be intermittent in
nature. The flight path has been designed to parallel Casa Street along the length of the structure
to minimize the noise impacts to nearby residential units. Additionally the raised height of the
helistop structure will increase the distance of the noise source from surrounding residences.
The applicant's submittal package indicates that detailed noise analyses will accompany plans
for a building permit.
CONCURRENCES
Attachment 3 contains a letter form Bill Robseon, staff person to the Airport Land Use
Commission (ALUC). His letter notes that the proposed helistop is outside the boundaries of the
San Luis Obispo County Regional Airport Land Use Plan and that the ALUC does not have
review authority over the request. The comments from other City departments have been
incorporated as conditions or code requirements as part of the approved minor or incidental
architectural review and are reiterated in the attached draft resolution.
FISCAL IMPACT
When the General Plan was prepared, it was accompanied by a fiscal impact analysis, which
found that overall the General Plan was fiscally balanced. Because the proposed project is
consistent with the General Plan, it is compatible with this finding.
ALTERNATIVE
Continue consideration of the resolution with direction to the staff and applicant if the Council
desires further-information or analysis to render support for the previous approval of the helistop
design.

Project Description:
Sierra Vista Regional Medical Center has served the San Luis Obispo Community for over 30
years providing trauma services for residents and visitors to San Luis Obispo County and the
surrounding areas. In order to more quickly transport patients to and from Sierra Vista Regional Medical
Center, Sierra Vista is proposing a new Helistop, to be built atop the newly completed parking structure
at the Medical Center at the corner of Foothill Boulevard and Casa Street.
The Sierra Vista Medical Center is an approximately twelve-acre parcel generally bounded by Foothill
Blvd. to the north, Stenner Creek to the west, Murray Ave. to the south, and Casa Street to the east. The
entire site is currently zoned Office (0). Surrounding uses are primarily medical offices with some high
density residential to the east, church and high density residential to the north, Stenner Creek, medical
offices, and Highway 1 to the west, and a mix of single-family residential, office, and Santa Rosa Park
to the south.
The application request includes the following items:
Architectural Review Commission: Architectural Review Committee approval.
Variance: A variance to the 25 feet height standard for the helistop pad to allow it to extend to the
height of the parking structure of 42'-7. A variance to the 25 feet height standard for the new parking
structure was approved for 45' in 2005 and is built out at 42'=7.
Helicopter landing facilities are commonly referred to by a variety of names including heliport,
helistop, helipad, etc. All, in their most generic sense, describe a place for helicopters to land and take
off. The Sierra Vista Regional Medical Center facility is technically a "helistop" as it will be a facility
where helicopters simply pick up or drop off patients. Other activities (helicopter storage, maintenance,
refueling, training, etc.) that might take place at a full heliport will not be undertaken at Sierra Vista. An
exception is that we sometimes use the term"helideck" to physically describe an elevated helistop.
Another is when referencing specific documents or permits that have the term "heliport" in their title
such as the "Heliport Permit" issued by Caltrans' Division of Aeronautics.
The parking structure is a 5 level structure holding 523 stalls over 165,700 square feet. One level
is below grade so the structure's height is in line with a four level structure. To the top of the tallest
shearwall the parking structure is 42'-7" tall. The parking structure is two bays wide, (133'-3" wide and
282'-6" long) and dead-ends at grid line 8, (please see the Helistop Plan on A2.1 in the drawing
package). The helistop platform is 42'-7" above ground level. The helistop will be supported by
columns along gridlines 5, 6 and 7. The columns will be concrete and are proposed to align horizontally
with the existing columns. The column's color will match the color of the existing parking structure. An
approximately 36"deep steel wide flange beam will span the 62' from the column on grid line C to the
column on grid line B, (column to column over the westerly drive aisle and parking stalls). The steel
beam will also be painted to match the parking structure's color scheme. The aluminum helistop will sit
on top of the steel beams. The helistop has been designed to appear as an extension of the parking deck
and the level of the helistop matches the level of the adjacent shear wall. The flight path is proposed to
be parallel to Casa'Street and will run along the length of the parking structure.

Sierra Vista Parking Structure Helistop August 19,2009
WDI#01015 Tr Page 4 of 8
The helistop is 54'x54' in size, (2,916 square feet) and will have an emergency stair exiting
toward Casa Street and an accessible ramp in the direction of the elevator closest to the hospital. There
will be a 6' wide safety net around the perimeter of the helistop. The safety net is almost horizontal but
angles slightly back toward the helistop so that in the event of a person or object falling on the net, they
will naturally roll back toward the helistop for retrieval. Since the helistop is supported by vertically
extending the existing concrete load bearing columns of the parking structure, no parking stalls will be
lost due to the footprint of the helistop, and it will have approximately 8'-6" of clearance to allow
vehicles to safely pass under it to park. Two parking stalls are lost to allow for the stair and fifteen
parking stalls are lost due to the accessible ramp. A total of seventeen parking stalls will be lost to
accommodate the stairs and accessible ramps for exiting from the helistop, however within the Sierra
Vista Master Plan there is still a surplus of parking. Please see chart at the end of the Project Description
document showing Sierra Vista Medical Center's Parking Demand and Supply information.
The helistop has been designed to support the UH-1 "Huey" which is similar in size with the Bell
212 and 412. This size aircraft is operated by commercial EMS and public safety operators. "Huey"
sized helicopters are only slightly larger than CALSTAR's Bell 222, based nearby at Santa Maria
Airport. Based on the request of the National Guard along with a potential need to accommodate larger
helicopters in the event of a disaster, Sierra Vista is proposing to also allow the HH-60G Pave Hawk,
Sikorsky Blackhawk) to land at this facility in rare emergency situations. The expected frequency of
typical commercial EMS helicopters is three times per month, and the expected frequency of the
Blackhawk is one time per year. The Blackhawk is expected to land at the helistop very rarely, and only
in the case of an emergency at nearby Camp Roberts or Camp San Luis, or in the case of a disaster in the
area.
Every effort has been made to minimize the appearance of the helistop by lowering its elevation
as far as possible; painting it's beams to match the parking structure, using the parking structure's
columns to support it, and placing it next to the dead-end, (as opposed to above the dead-end) on the top
deck of the parking structure. These design elements allow the helistop to blend in with the parking
structure to the greatest extent possible. It is not possible to screen the helistop since any elements
extending above the helistop level would be considered obstructions and would not be allowed by the
FAA or Caltrans Division of Aeronautics (state permitting agency). The helistop and the surrounding
environment have been very carefully designed to meet_ all airspace obstruction-clearance requirements,
a primary element of helistop design.

Benefits to the Community: .
A helistop at Sierra Vista will save lives by drastically reducing the transport time of patients
who need to quickly arrive to the Medical Center after suffering an accident or health emergency. In
addition, the transportation time of Sierra Vista patients in need of specialized healthcare services of
academic medical centers in Los Angeles or the Bay Area will be greatly reduced. The main reason for a
helistop at Sierra Vista is to save lives by providing an efficient and effective means of transportation to
ensure the residents and visitors of San Luis Obispo have access to specialized healthcare services as
quickly as possible.
An integral part or component of any trauma system is the ability to quickly triage and transport
patients to the appropriate facility within the "Golden Hour". As noted by an independent consultant
hired by the SLO SMSA, trauma patients in San Luis Obispo County in need of neurological services
are often delayed up to 19 hours. Vast and rugged geography of many parts of the county poses
transportation challenges for critically injured patients. This helistop will provide an alternative to
ground transportation resulting in expedited care for patients, in which time is of the essence (trauma,
stroke, and cardiac patients).
With the only Level II Neonatal Intensive Care Unit (NICU) and high-risk pregnancy program
covering a 200 mile span, timely transportation to and from Sierra Vista will enhance the neonatal
services currently provided to this vast geographic expanse. In addition to transporting neonates to
Sierra Vista Medical Center there is an occasional need to quickly transport neonates out of the San Luis
Obispo region who require a higher level of care. Most often, the babies are ground transported to
Stanford University's Lucille Packard Children's hospital —a five hour ambulance ride. A helistop at the
Sierra Vista Medical Center will enable these vulnerable babies to be transported to the appropriate
facility much more quickly.
At the request of the National Guard, due to our proximity to Camp Roberts and Camp San Luis,
we have designed the parking structure and helistop to accommodate a Blackhawk helicopter. Due to
the tertiary services provided at Sierra Vista, The Medical Center serves as the hospital of choice when
foreign agencies and other special interest groups train at both Camp Roberts and Camp San Luis.
In the event of a natural disaster, there is a high probability of limited vehicular access to and
from the City of San Luis Obispo. This helistop would enhance the Medical Center's ability to provide
emergency supplies and services to our community during a period of highway closures.

Fire Protection:
The helistop will not provide refueling for helicopters so no fuel will be stored onsite. The
Sprinkler system shall be extended to cover the under-pad area. Extending the sprinklers from the floor
below or providing a new, supervised floor zone will need to be coordinated with the Fire Marshall.
Hydraulic calculations from the original project indicate there is adequate water pressure for an
ordinary, group 2 hazard, typical of a parking structure. An aqueous film forming foam (AFFF) system
shall be provided per NFPA 418. A dry standpipe will be required adjacent to the ramp to the pad.
Extending the (e) DSP from the floor below will probably place 4" piping below (e) concrete beams.
Plumbing System:
The surface of the helistop will slope from gridline 7 to gridline 5 to direct spilled fuel away
from the emergency exit stair and the accessible ramp, and to collect any spilled fuel in a gutter. Surface
runoff will then be funneled to a temporary holding tank that will be suspended beneath the helistop. A
truck will then drive beneath the helistop and pick up the fuel for disposal.
The Storm drainage rainfall rate is 2" per hour. A lift station is not required as there is adequate
height for gravity flow. The helistop surface will drain to perimeter gutters. The gutters will slope to an
outlet that will extend to a new fuel— oil/water separator. The separator outlet will extend to (e) storm
drainage system at the floor below. Service access will be required at the separator.
Lighting Impacts:
Red warning lights will need to be added to the roofs of both elevator towers and the helistop
itself to assist helicopter pilots to locate and safely land on the helistop. These lights will only be in use
when a helicopter is landing on the helistop. The estimated time these lights will be on is 30 minutes at a
time. The lights will either be controlled by a photo-control and activated by Sierra Vista staff at the
direction of the helicopter pilot once the helicopter is close to the facility or will be activated by the
helicopter pilot as the helicopter approaches the helistop. A lighted windsock will be located at the
corner of Foothill Boulevard and Casa Street on the top level of the parking structure. The windsock
pole will be approximately 10' tall.
The roof of the parking structure is presently lighted from four light poles each provided with
two (2) fixtures. At least two, (possibly three) of the existing pole mounted lights on the top level will
need to be taken down since they are obstructions that could be in conflict with helicopter blades and
therefore represent a potential danger to helicopter pilots and the people they are transporting..The
removed fixtures are proposed to be reinstalled on the remaining two poles at a lower elevation to .
supplement deck lighting. New surface mounted shielded lights will be installed on the short center
concrete bollards to light the parking stalls on the main deck. The heliport structure will cover portions

of the roof parking ramps so new lights will be attached to the underside of the helistop structure to light
the ramps and parking stalls. The pedestrian ramp and stair off the helistop will also be provided with
handrail lights. Pending completion of the new photometric study, it may be necessary to add lights to
the inside of the shearwalls at the perimeter of the building to equal existing light levels. The existing
light level footcandles will be restored to the top level of the parking structure, and a photometric study
will be submitted at plan check. This will require a greater number of fixtures, mounted lower and
behind walls, which will greatly reduce the overall nighttime light pollution to the surrounding
community.
Noise Impacts:
The flight path for helicopters landing and taking off from the helistop at Sierra Vista is proposed
to be parallel to Casa Street, or along the length of the parking structure. This will minimize noise by
limiting overflights of nearby residences. Due to the elevated location of the helipad, noise from
helicopter landings and takeoffs will be significantly reduced due to the increased distance between the
helicopters and nearby residences. A UH-1 "Huey Aircraft" typically generates a maximum noise level
of 93 dB at a distance of 150 feet; the Blackhawk helicopter produces a similar noise level. The
majority of the landings will be performed by smaller sized Bell 212, 222 and 412 which are operated by
commercial EMS and public safety agencies and also generate about 93 decibels. The pilots will make
their best attempt to follow "Fly Quiet" procedures, which involve steeper takeoff and landing slopes.
Fly Quiet procedures typically reduce noise levels by 2 to 6 dB.
Long-term (48-hour) and short-term, "spot"noise measurements were recently conducted at
various locations along Murray Street, Casa Street, Foothill Boulevard, and in Mustang Village to
quantify the existing noise levels in these residential areas. Once the flight paths and helistop
layout/design is finalized, computer-generated noise contours will be prepared to illustrate the noise
footprint" of the helicopter flights. The noise contours will then be compared to the existing noise
levels at the residential areas to determine whether there will be noise impacts from the use of the
helipad. This additional information will be provided at plan check.

To: Jeffrey W. Wright and Mark Jensen, Heliplanners Aviation Planning Consultants
From: Bill Robeson, Development Review/Airport Planner-County of San Luis Obispo
Subject:Proposed Helistop at Sierra.Vista Regional Medical Center
This letter is to confirm that the proposed helistop at Sierra Vista Regional Medical
Center is located outside the boundaries of the San Luis Obispo County Regional Airport
Land Use Plan (ALUP). The ALUP's Aviation Safety Area map(Figure 1) shows that the
ALUP Boundary or Planning Area extends to the north of the airport and ends near
Madonna Road and Orcutt Road within the city limits of San Luis Obispo. Also attached
is an aerial photo (Figure 2) showing the location of the relevant roads,the airport and
the Sierra Vista Regional Medical Center. The comparison of Figures 1 and 2
demonstrates that the location of the medical center well to the north of the ALUP
boundary. According to the ALUP, Section 2.8.1 Existing Land Use, "The ALUP applies
only to new development within the Planning Area." Because of this, the Airport Land
Use Commission does not have review authority concerning the helistop at Sierra Vista
Regional Medical Center. Please call me with any further questions.
Sincerely,
Bill Robeson

Santa Ana, CA 92707
SUBJECT: 84-09: 21 Casa Street
Review of changes to an existing parking structure to accommodate a
helistop for Sierra Vista Hospital.
Dear Mr. Beck:
On November 6, 2009; 1 reviewed your plans to add a helistop on the roof of the
parking structure at 21 Casa Street in the Office (0) zone. I have determined that the
project is minor or incidental and will not require review by the Architectural Review
Commission. I have approved your plans, based on findings, and subject to conditions
of approval, and noting code requirements, as follows:
Findings
1. The proposed project will not be detrimental to the health, safety and welfare of
persons living or working at the site or in the vicinity because the preliminary plans
have been reviewed by all applicable City Departments for consistency.with
relevant codes and regulations.
2. The project is consistent with the Community Design Guidelines because the
new helistop has been designed .to blend with the architectural lines of the
existing parking structure and be as inconspicuous as possible by incorporating
the following:
a. The elevation of the helistop has been lowered as much as feasible on
the parking structure's roof deck;
b. The beams of the helistop will lie painted to match the parking structure,
and
c. The helistop will be supported by the beams of the parking structure;
3. The proposed helistop will provide an important function and purpose for the
hospital campus..
4. Revised parking calculations submitted with the helistop application demonstrate

A RESOLUTION OF THE SAN LUIS OBISPO CITY COUNCIL
APPROVING A HELISTOP ON THE ROOF OF THE SIERRA VISTA HOSPITAL'S
PARIQNG STRUCTURE AT 21 CASA STREET (ARC MI 84-09)
WHEREAS, Sierra Vista Medical Center has requested to operate a rooftop helipad or
helicopter landing facility (hereafter referred to as a helistop) atop the parking structure located
at 21 Casa Street on its hospital campus in the City of San Luis Obispo; and
WHEREAS, the proposed helistop will accommodate emergency medical service (EMS)
and public service medical helicopters and will facilitate the care of patients who are airlifted to

WHEREAS, the proposed helistop will facilitate helicopter operations at an elevated
location that will mitigate noise and other impacts on pedestrians, motorists and surrounding
properties; and
WHEREAS, California Public Utilities Code Section 21661.5 (b) requires that the City
Council or its designated design review authority approve plans to construct a helistop located
within City boundaries; and
WHEREAS, the Community Development Director approved through a minor or
incidental architectural review application the design of the helistop on November 6, 2009 and
made appropriate findings as to the reasons why the requested helistop does not conflict with
surrounding land uses; and
WHEREAS, notices of the Director's action were made at the time and in the manner
required by law; and
WHEREAS, the project is categorically exempt under Class 11, Accessory Structures,
Section 15311 of the California Environmental Quality Act(CEQA)Guidelines; and
WHEREAS, the proposed helipad complies with federal requirements, and a City
Council resolution noting City approval of the helistop is required for a final approval from state
authorities..

Findings
1. The proposed project will not be detrimental to the health, safety and welfare of persons
living or working at the site or in the vicinity because the preliminary plans have been
reviewed by all applicable City Departments for consistency with relevant codes and
regulations.
2. The project is consistent with the Community Design Guidelines because the new
helistop has been designed to blend with the architectural lines of the existing parking
structure and be as inconspicuous as possible by incorporating the following:
a. The elevation of the helistop has been lowered as much as feasible on the parking
structure's roof deck;
b. The beams of the helistop will be painted to match the parking structure; and
c. The helistop will be supported by the beams of the parking structure;
3. The proposed helistop will provide an important function and purpose for the hospital
campus.
4. Revised parking calculations submitted with the helistop application demonstrate that
there will still be a surplus of 64 parking spaces for the hospital campus above City code
requirements even with the removal of the 17 parking spaces on the roof of the parking
structure to accommodate development of the helistop.
5. The project is categorically exempt under Class 11, Accessory Structures, Section 15311
of the CEQA Guidelines.
Conditions
1. Final project design and construction drawings shall be in substantial compliance with the
project plans submitted as part of this minor or incidental architectural review
application. Any change to approved design, colors, materials, or other conditions of
approval must be approved by the Director or Architectural Review Commission, as
deemed appropriate.
2. Project lighting details including photometrics shall be submitted along with plans for a
building permit. As indicated in project application materials, the goals are to keep light
fixtures as low as possible in height and to keep illumination levels to a minimum,
thereby reducing impacts to the night sky and surrounding neighborhood, but still
meeting safety requirements.
Code Requirements
1. Building elements shall have a fire-resistance rating not less than Type IIA construction.
2.
