Spring Valley Village City Council
Agenda Item Data Sheet
MEETING DATE: November 18, 2025
SUBMITTING STAFF: Jasmin Torres, City Secretary
SUBJECT: DISCUSSION AND DIRECTION CONCERNING: Public
Infrastructure and Design Manual as applied to the
Replacement of Existing Infrastructure
BACKGROUND:
In February 2021, City Council adopted the Public
Infrastructure Design Manual (PIDM) to establish consistent
standards for the design and construction of public
infrastructure throughout the City. The PIDM outlines
specifications for roadway and utility materials and sets a
minimum roadway width of 28 feet, measured back of curb to
back of curb.
While the PIDM governs general roadway and material
standards, it does not specifically define cul-de-sac
geometry. The City follows the adopted Fire Code for those
design parameters, which establishes turning radius
requirements to ensure that emergency vehicles have
adequate access and maneuverability.
Since the adoption of the PIDM, the City has designed and
completed three roadway projects that have incorporated cul-
de-sacs meeting or exceeding the 40-foot radius
recommended by the Fire Code. These projects illustrate the
City’s consistent application of the PIDM and Fire Code
where site conditions allow.
As the City continues roadway reconstruction projects under
the PIDM, some areas present physical limitations that affect
the ability to fully implement the standard 40-foot-radius cul-
de-sac. These constraints are typically the result of existing
right-of-way (ROW) widths, established development
patterns, and roadway alignment or length.
A key example of these constraints can be found on Spring
Oaks Circle, where the total ROW measures 30 feet, with
Page 3 of 30

[PAGE 4]
approximately 25 feet currently occupied by the existing cul-
de-sac. Because additional ROW is not available, and
acquisition would significantly impact adjacent residential
properties, the cul-de-sac is being replaced in kind at 25 feet.
This maintains access within the existing ROW limits.
The Croes project area presents a similar challenge,
particularly at the north end, where the roadway extends
approximately 1,000 feet and includes a curve. This roadway
length necessitates an adequate turnaround area to support
safe emergency and service vehicle access. In collaboration
with the Fire Department, City staff evaluated potential
options within the existing ROW and determined that a 30-
foot-radius cul-de-sac would provide the necessary
functionality for emergency ingress and egress while
remaining feasible within the available space.
Variations in cul-de-sac dimensions across recent projects
are the result of right-of-way constraints and roadway
configurations, not inconsistencies in the application of City
standards. The City continues to apply the Public
Infrastructure Design Manual and adopted Fire Code
consistently, using engineering and public safety judgment to
adapt designs appropriately to each site.

1. Fire hydrants shall meet or exceed all applicable requirements of the latest revisions of ANSI/AWWA Standard C502. Fire hydrants shall be UL 246 Listed, FM 1510 Approved and
certified to ANSI/NSF 61 & 372.
2. Fire hydrants shall have a UL – FM – AWWA Water Working Pressure (WWP) rating of 350 psig (24 barg). Fire hydrants shall be production pressure tested in the fully closed and
fully open positions to 700 psig (48 barg). Fire hydrants shall be UL and FM proof-of-design tested at 1400 psig (96 barg).
3. Fire hydrants shall be of the compression type, opening against the pressure and closing with the pressure.
4. Fire hydrants shall have a minimum 5-1/4” main valve opening and a nominal inside lower/upper barrel diameter (I.D.) of 6.9” to assure maximum flow performance. Pressure loss at
1,000 GPM shall not exceed the following values:
4” Pumper Nozzle: 2.70 psi

4.5” Pumper Nozzle: 2.50 psi

5. Fire hydrants shall be three-way in design, having one 5” integral STORZ pumper nozzle with latching cap and two 2-1/2” NTS threaded hose nozzles. Nozzles shall thread
counterclockwise into hydrant barrel utilizing O-ring seals. A suitable nozzle lock shall be in place to prevent inadvertent nozzle removal. Nozzle caps shall be secured to the hydrant
by a galvanized chain that meets ASTM A-467-64 Class MT.
6. The bonnet assembly shall provide an oil reservoir and lubrication system that automatically circulates lubricant to all stem threads and bearing surfaces each time the hydrant is
operated. The bonnet shall have a service plug to facilitate oil replacement when the hydrant is serviced. This lubrication system shall be sealed from the waterway and any
external contaminants by use of O-ring seals. An anti-friction washer shall be in place above the thrust collar to further minimize operating torque. The oil reservoir shall be factory
filled with a low viscosity, non-toxic, NSF H1 Approved Hydrant Lubricant which will remain fluid through a temperature range of -400 F. to +1500 F.
7. The operating nut shall be a one-piece design, manufactured of ASTM B62 or B584 bronze. Operating nut shape and dimensions shall be as specified by the end user. The
operating nut shall be affixed to the bonnet by means of an ASTM B62 or B584 bronze hold down nut. The hold down nut shall be threaded into the bonnet in such a manner as to
prevent accidental disengagement during the opening cycle of the hydrant. The use of set screws as a means of retention is unacceptable. A resilient weather seal shall be
incorporated into the hold down nut, for the purpose of protecting the operating mechanism from the elements.
8. The direction of the opening shall be left to open. An arrow and the letter L shall be cast on the bonnet flange to indicate the specified opening direction.
9. A stainless steel tag shall be attached to the upper barrel of the hydrant that indicates the hydrant bury depth. The tag shall be designed so that it is still readable after multiple
hydrant paintings.
10. The hydrant bonnet shall be attached to the upper barrel by not less than eight bolts and nuts and sealed by an O-ring.
11. Hydrants shall be a “traffic-model” having upper and lower barrels joined at the ground line by a separate and breakable “swivel” (traffic) flange providing 3600 rotation of upper
barrel for proper nozzle facing. Traffic flange shall employ not less than eight bolts. Traffic flange segments shall be located under the upper barrel flange to prevent the segments
from falling into the lower barrel when the hydrant is struck. Traffic flange shall be tested by an independent certified testing agency to assure proper function under low speed
impact.
12.The upper and lower barrels shall have an O-ring pressure seal between the barrels. The proper ground line shall be cast clearly on the lower barrel and shall provide not less than
18” of clearance from the centerline of the lowest nozzle to the ground.

13. The operating stem shall consist of two pieces, not less than 1-1/4” diameter (excluding threaded or machined areas) and shall be connected by a stainless steel safety coupling.
14. Operating stems shall be protected from corrosion by electrophoretic coating (e-coat) or FBE (powder coat).
15. The stem coupling shall have an integral internal stop to prevent the coupling from sliding down into the lower barrel when the hydrant is struck. The stem coupling shall be
designed to break on traffic impact and so that impacted pieces shall not fall into the hydrant main valve. Proof of design impact testing to be performed at a certified independent
test facility.
16. The lower barrel shall be an integrally cast unit composed of ASTM A126 Class B grey iron or ASTM A536 ductile iron. The use of threaded flanges or flanges mechanically
attached to barrels or pipe is deemed unacceptable. The hydrant bury depth shall be clearly marked on the hydrant lower barrel.
17. Main Valve shall be constructed of an iron core encapsulated in molded rubber having a Shore A Durometer hardness of 95 +/- 5 and shall be reversible in design to provide a spare
in place, it also shall be rated for 350PSI on either side of the main valve. Plastic (polyurethane) main valves are unacceptable. The main valve shall have a cross section not less
than 1”.
18. Hydrants shall be equipped with (2) two drain valves which drain the barrel when the hydrant is closed and seal per AWWA C502 requirements when the hydrant is opened. These
drain valves shall be an integral part of the one-piece bronze upper valve plate. They shall operate without the use of springs, toggles, tubes, levers or other intricate synchronizing
mechanisms.
19. The upper valve plate, seat ring and drain ring (shoe bushing) must be ASTM B62 or B584 lead free bronze alloys and work in conjunction to form an all bronze drain way. A
minimum of two (2) internal and two (2) external drain openings are required. Drains ported through an iron shoe are not permitted.
