DATE: JANUARY 23, 2006
SUBJECT: DISCUSSION REGARDING DESIGN OF THE SIERRA MADRE AVE. PEDESTRIAN
UNDERPASS FOR THE ROSEDALE PROJECT
It is recommended that the City Council hear the proposed design options for the pedestrian
underpass, and direct the final design concept to be consistent with Photo 2 of Exhibit E-1 attached,
with approximate dimensions of 10 -12 ft. high by at least 20 ft. wide.
i
BACKGROUND
The Rosedale Specific Plan provides for a major open space feature referred to as The Arroyo, which
is an organizing element for the various planned neighborhoods, and provides a connection from the
southern end of the project to the foothills. The Arroyo will feature a meandering waterway, bio-
filtration ponds avid lighted walking paths. The concept in the Specific Plan also includes a
pedestrian underpass at Sierra Madre Ave. to avoid hikers/pedestrians having to interact with
vehicular traffic.
While the ultimate design of the underpass was not mentioned in the Specific Plan (leaving that to
subsequent more (precise design efforts), a condition of approval was imposed as part of the
entitlements. Condition No. 23 reads as follows:
I
-23. SIERRA MADRE AVE. _UNDERCROSSING
Prior tolrecordation of a subdivision map (except for a map(s) for financing and/or
conveyance purposes only) that includes the realignment of Sierra Madre Boulevard,
subdivider shall, in a manner meeting approval of the City Engineer.
a. Design the pedestrian undercrossing with adequate width,
j vertical clearance and grades.
b. Design necessary drainage facilities for proper disposal of
storm runoff.
C. Design adequate lighting and other design elements to
ensure maximum security."
In order for the underpass to function as an integral component of the trail in the Arroyo, it is
essential that the underpass be a safe facility, where trail users of all ages would feel secure and
comfortable.
Original Design
During the. rough grading plan stage of the Rosedale project, the Developer, Azusa Land Partners
(ALP), proposed a tunnel under Sierra Madre Ave. that began at the toe of a manufactured slope on
the north side of Sierra Madre Ave. and ended at the toe of a manufactured slope on the south side.
Due to a combination of factors, the length of the tunnel would have been 130 ft. See Exhibit A.
These factors include the depth and number of utility lines planned for Sierra Madre Ave., the 2:1
slope condition, and the grade of the trail for handicap access. The proposed structural material was
a prefabricated corrugated steel pipe arch.
!ALP suggested that in lieu of such a long tunnel with potential public safety concerns, the City could
opt for eliminating 'the tunnel in favor of an at -grade crossing at the lighted intersection of Sierra
Madre Ave. and Azusa Veterans Way. Staff responded by stating that an underpass would still be
desired, but that it would need to be redesigned for maximum public safety, which could be
accomplished by shortening and widening of the underpass. Photos of a bridge structure seen in
Canada, was provided as an example of a safe -feeling grade separation.
Second Design Proposal
ALP prepared a new underpass design featuring a shorter tunnel in response to Staff comments. See
Exhibit B-1 through B-3. This was accomplished by using retaining walls at both ends of the
underpass, thereby;shortening it to 55 ft. The structural material continued to be corrugated steel,
but the retaining wall ends of the underpass facility would feature stone/concrete enhancements.
Dimensions of the opening would be 9' 2" high by 12' wide.
Because of the depth of utilities in Sierra Madre Ave. however, the pedestrian under -crossing would
be about 24 ft. below the surface of Sierra Madre Ave. The combination of underpass depth and use
of a pipe arch still posed public safety concerns in Staff's opinion, due to the inability to effectively
view the area inside the underpass. It was suggested to ALP to investigate rerouting of some of the
utility lines to reduce the thickness of the Sierra Madre Ave. section, thereby raising the elevation of
the underpass Floor, and to "open -up" the tunnel -like feel of the pipe arch possibly by using a
rectangular box instead.
Latest Design Proposal
Exhibit C shows the latest design proposal, featuring a corrugated steel pipe arch and decorative
stone/concrete retaining wall ends. The underpass would be 55 ft. long, measuring 14 ft. wide, and
9 ft. high at its highest point. By relocating a sewer line and storm drain in Sierra Madre Ave., the
bottom of the Arroyo at the underpass will be 16 ft. below the surface of Sierra Madre Ave. This is a
much -improved design over the previous ones, and responds to most of Staff's issues and concerns.
Discussion
The most recent design proposal of the underpass could still benefit from being "opened -up" to
I
make it safer. A lalger opening or a rectangular box could potentially accomplish this. Council
should discuss the type of building material desired, as well as size of the underpass. Keep in mind,
that the taller the opening of the structure, the lower in the Arroyo it will need to be constructed to
accommodate the utility lines in the Sierra Madre Ave. street section.
ALP has submitted information concerning available prefabricated structures. This is presented in
Exhibit D. Examples of existing underpasses are presented in Exhibit E-1 and E-2. It would appear
that Photo 2 in Exhibit E-1 would best address the City's safety concerns. This type of underpass
structure measuring at least 20 ft. wide, with a height of 10 to 12 ft. would provide a large enough
opening to accom odate public view into the underpass to enhance public safety.
Extensive lighting inside and outside the underpass is a must, using ceiling -mounted vandal -proof
glass. The exterior, of the retaining walls can be finished in stone veneer, or stamped concrete.
Because of the native rock in the area, river rock may be the most desirable.

CONTECW MULTWLATEo structures provide designers of
stormwoter management systems, underpasses and bridges
with a versatile method of construction and a long history of
strength, durability and economy. A variety of shapes and
sizes ensures that MULTI -PLATE structures fit most applica•
tions. Ease of design, construction and proven reliability
make them the frequent choice of experienced engineers.
MULTI -PLATE structures are made from sturdy, heavy gauge
corrugated steel plates that are pre -formed to various
shapes and sizes, then galvanized for long-term protection
and performance. The plates are delivered to the job site
and bolted together to farm a MULTI -PLATE structure
optimally suited fo, the project.
MULTI -PLATE is available in full round, arch, pipe -arch,
horizontal and vertical ellipse, underpass, box culvert and
long -span shapes -i -all in a wide range of sizes. Since
1931, MULTI -PLATE has been proven to offer:
Superior durobilify
MULTI-PLATE"s heol y gauge steel uses an industry standard
3 oz. pe? square fbaI galvanized tooting capable of
providing a service life of 75 years or longer. More
Information covered on page 8.

High loadcarryirig capacity
As a steel -soil interoction system, MULTI -PLATE is
designed to carryhigh combined live and dead loads.
High traffic loads and deep cover applications are a
MULTI -PLATE SPECIALTY.
Eadfer, faster installation
Prefabricated plotes are assembled in the field, translating
into finished cons"cCon in days instead of weeks as with
most concrete structures. - -

Descriptions at plata
MULTI -PLATE plates are Reid assembled into pipe, pipe.
arches, ellipses, arches, box culvars, and underpasses.
Corrugations of 6 -inch pitch and 2 -inch depthrore at right
angles to the length of each plate.
Thickness. Standard specified thickness of the galvanized
ploles varies From 0.111 to 0.375 inches.
Widths. Standard plates are Fabricated in five net covering
widths, 28.8 inches, 48.0 inches, 57.6 inches, 67.2
inches, and 76.8 Inches. Sea Table 10.
The "pi" nomencloture translated circumference directly into
nominal diameter in inches. For example, four 15 -pi plates
give a diameter of 60 inches; four 21 -pi plates provide an
844nch diameter, etc. Various plate widths may be
combined to obtain almost any diameter.
Lengths. MULTI -PLATE plates are furnished in either 10400t
or 12 -foot nominal lengths. Actual length of the squareend
structure is about four inches longer than its nominal length
because a 24nch lip protrudes beyond each end of every
plate for lapping purposes.
Bolt holes. The plates ore punched with 7/8 -inch holes on
3 -inch centers to provide the standard four bolls per foot of
longitudinal seam, in two staggered rows on 2 -inch centers.
They may also be punched to provide either six or eight,
bolls per foot of longitudinal seam on 0.280 inch thickness
material, if required.One-inch holes, punched 8 bolts per
foot of long seam, are used for .3184nch and .3804nch
thick, malarial.
The inside crests of the end corrugations are punched with
1 -inch -diameter holes for circumferential seams on centers
of 9.6 inches or 9'°/32 inches (equals 3pi).
