2.04 Fire Hydrants and Associated Water Mains
A. MANDATORY CODES AND STANDARDS (latest editions)
1. State of Maryland Fire Prevention Code NFPA 1 National
Fire Prevention Code
2. State of Maryland Model Performance Code (BOCA National
Building Code --. Section 917)
3. WSSC - Washington Suburban Sanitary Commission (Note:
Projects not in the jurisdiction of the Washington
Suburban Sanitary Commission (WSSC), substitute local
water authority, State of Maryland Plumbing Code,
International (BOCA) Plumbing Code and NFPA 24 as
applicable)
B. GENERAL DESCRIPTION
a. The campus receives water supply from WSSC and by legal
agreement, complies with WSSC rules and regulations,
including, but not limited to design standards and
specifications.
b. The campus facilities are serviced by two methods:
metered and unmetered.
Metered: The contiguous campus is connected to WSSC by a
number of underground fire flow bypass meters. The double
meters record ordinary domestic flow and when large
volumes are demanded, open a second, larger size meter.
Unmetered: Individual buildings and locations generally
not on the contiguous campus have unmetered systems where
all fire protection systems are supervised for flow with
an executed fire supervision agreement with WSSC. The
alternative is a meter set in the building or an outside
shed constructed for the purpose.
c. The campus system between the WSSC meters and the various
buildings and site facilities is the "campus on-site"
system, and consists of mains up to 12 inches in diameter
of various ages and conditions. Individual buildings and
locations not on the campus are "on-site" systems for
those buildings or complexes and usually consist of a
single main.
d. The campus on-site system is the underground distribution
from WSSC meters for all campus building and facilities
including, but not limited to, domestic, irrigation,
mechanical, fire protection systems, and fire hydrants.
Individual building or complex on-site systems provide
services required for the individual building or
facilities.
e. The campus on-site system with multiple supply point
meters, loops, and grids minimally performs at 2,000
gallons per minute (qpm) at 20 pounds per square inch
(psi) fire flow over almost all the system. Individual
building or complex facilities were provided fire flow in
accordance with the calculated facility requirements.
C. WATER SERVICE
a. Sufficient fire flow shall be provided for the individual
project as determined by a recognized standard method.
Fire flow is additive to-all other-demand flows. The
campus on-site system extension by loop, grid, or
individual fire hydrant shall result in not less than
2,000 qpm at 20 psi residual. Individual buildings or
complexes shall meet minimum WSSC criteria (1,000 qpm at
the last fire hydrant and 500 qpm additional at the
adjacent fire hydrant at not less than 20 psi residual).
b. The minimum size of additions or replacement mains to the
campus on-site system (loop or-grid is 8-inch. Mains to
single fire hydrants are minimum 6-inch but must maintain
minimum fire flow. The minimum size of on-site mains to
individual buildings shall be as calculated and meet WSSC
criteria (minimum 8-inch where the fire flow requirement
is over 1,000 gpm).
D. VALVES
a. In the campus on-site system, gate valves shall be
provided to sectionalize the system so that any outage
will minimally affect fire protection.
1. Valves shall be provided for each hydrant lead-in
connection so that no more than one fire hydrant
may be out of service at any time.
2. Valves shall be installed so that fire hydrants and
fire suppression systems for an individual building
will not be out of service at the same time.
3. Valves shall be installed on each side of a tee or
cross to maintain the loop or grid flow.
b. Valves shall be located in streets, sidewalks or other
paved surfaces. Where a paved surface is not possible,
valve boxes shall be set in a 12 inch by 12 inch by 4
inch deep reinforced concrete square.
c. Valve box covers shall be marked "WSSC WATER" where owned
and maintained by WSSC and "WATER" on the campus on-site
system and where owned or maintained by the university.
E. FIRE HYDRANTS
a. The number and spacing of fire hydrants provided shall be
sufficient for the calculated fire flow and distribution
requirements.
1. The campus on-site system requirement is
approximately 300 feet between fire hydrants.
Individual building or complex fire hydrant spacing
is project dependent (WSSC criteria for dense,
built-up areas is 250 to 300 feet).
2. Provide additional fire hydrants if the building is
more than 300 feet from an existing campus on-site
fire hydrant or public (WSSC) fire hydrant.
3. Fire hydrants should be available so that the
first-hydrant is no more than 100 feet from the
building and the-second fire hydrant no more than
400 feet from the building.
4. A fire hydrant shall be within 100 feet of a fire
protection system fire department connection
(siamese).
b. Fire hydrants shall be located only on streets and fire
lanes as follows:
1. Locate at street and fire lane intersections but
not within 15 feet of the intersection.
2. Locate fire hydrants on public sides of street or
fire lane access controls (gates, bollards).
3. Locate fire hydrants 2 feet from curbs and streets
(per WSSC detail). Exceptions shall not be granted
except in case of unusual site conditions.
4. The pumper connection shall directly face the
street or fire lane. Elevations of the center line
of the pumper connection shall be between 12 and 24
inches above finished grade.
5. Locate fire hydrants so there are no obstructions

yellow (paint # or equal) with black
(paint # or equal) tops and caps (2,000
gpm and over at 20 psi). (Note: for fire hydrants
under 2,000 gpm, the cap and top colors are as
listed in NFPA 291).
3. UMCP individual building or facility fire hydrants
(unmetered) are red (paint # or equal).
e. Unmetered fire hydrants under the WSSC fire supervision
agreement are electrically supervised as follows:
1. Waterflow alarm (pressure) switch (listed or
approved) in NEMA 4 enclosure strapped securely to
the hydrant barrel above grade. The switch is
provided with a 1/2 inch tap into the hydrant
barrel.
2. Metallic conduit, minimum 3/4 inch rigid with conductors.
3. Underground to building. Connect to building monitoring

contractor shall be required to remove and stockpile the
top 18" of soil in areas that are to be regraded or
otherwise disturbed. This includes staging areas and
areas where equipment or materials is stockpiled.
B. If the top 18" is found not to be suitable, it must be
amended to meet minimum specifications listed in item #2
prior to placement on site. In addition, soil prepared
for backfilling shall be protected from compaction and
contamination.
1. Landscape installation shall be accomplished by
companies that are skilled in landscape
installation and planting must be accomplished
during the appropriate season. The successful
bidder shall have on staff a "Certified
Professional Horticulturalist" or Registered
Landscape Architect and show proof of having
satisfactory completion of similar size landscaping
projects in both dollar value and size of plant
material to be installed.
2. Stripped soil used for the planting media shall be
tested by the contractor and amended if necessary
to meet specifications prior to placement on the
site. Soil shall be a sandy loam or silt loam in
texture with a minimum of 3% organic matter, stones
and debris no larger than 2", pH of 5.0 - 7.0, and
soluble salts not greater than 500ppm. Suitable
soil shall then be mixed with compost not to exceed
1/3 by volume and blended so the mixture is
uniform.
3. Placement of the backfill planting media shall be
done so there is no equipment driven over the top
soil. This will require that utilities be
installed at specified depth and landscape plants
be placed onto the sub-grade before installation of
soil backfill. After utilities and plants have
been installed, place soil and compact as specified
starting from one end of the site and working away
from finished areas.

(MDE), Water Management Administration, 2500 Broening
Highway, Baltimore, Maryland in conformance with the
requirements of the following two publications:
Stormwater Management Guidelines for
State and Federal Projects; and
Erosion and Sediment Control Guidelines
for State and Federal Projects.
Both publications are issued by the Maryland Department
of the Environment (MDE), Water Management
Administration.
B. Quantitative and qualitative stormwater management, as
required by the Maryland Department of the Environment,
shall be included in the site drainage design.
Stormwater Management must be addressed on a project if
more than 5,000 square feet of surface area is disturbed.
The University of Maryland College Park campus is
comprised of over 1,200 acres. Accordingly, the
particular approach to meeting stormwater management
requirements at UMCP often is somewhat different from
that which would be appropriate for a smaller self-
contained site. It is therefore necessary that the
approach to meeting SWM requirements be coordinated with
the University before submittal to MDE.
Furthermore, early coordination with the reviewing agency
(MDE) is essential to preclude delays. In general, a
site/grading plan adequately developed to provide a
complete sediment control plan and stormwater management
plan including required supporting calculations must be
submitted at or immediately following the Design
Development submittal stage.
C. Erosion and sediment control practices shall be in
conformance with:
1994 Maryland Standards and Specifications
for Soil Erosion and Sediment Control
published jointly by Water Resources Administration, Soil
Conservation Service and State Soil Conservation
Committee. Sediment and erosion control approval must be
obtained from MDE if more than 5,000 square feet of
surface area or more than 100 cubic yards is disturbed.
2.17 Tree Protection
A. Tree protection requirements are to be included in the
construction contract. Prior to beginning any
construction activity, the following steps are required
to protect trees from damage:
1. Identify trees which will remain on the site. This
includes not only those trees within the limit of
work but also those which may have critical root
zones within the area. This includes:
Chemical and fuel storage
Chemical waste of any kind
Concrete washout areas
Construction office placement and
subcontractors offices
Construction parking
Construction vehicle corridors
Crane placement and crane corridors for moving
material (if applicable)
Limb clearance of buildings and other features
approved by University
Material storage
Other sub-contractors working areas must be
approved by University
Painting procedures and clean-up
Soil stockpiling
Steel make-up areas
Trash stockpiling and hauling sites
The roots of a healthy tree growing in uncompacted
soil has a root system as much as five times the
spread of the canopy. This is the area which must
be initially considered.
2. Provide written report by a certified arborist
identifying root evaluations of the trees which are
in potential conflict with construction to
determine the critical root zones.
3. Provide written report by a certified arborist
indicating the best methods of construction which
will minimize the impact on the critical root zone.
Obtain specifications from the arborist for tree
protection as required for the specific project in
question with penalties to the contractor if the
protected areas are violated.
4. Specifications will include the requirement that
inspectors and contractors be trained as to the
reasons why intrusion into the critical root zone
will be detrimental to the trees' survival.
Training should occur prior to the start of
construction.
B. Do not store materials, soil, equipment, etc. within the
Critical Root Zone (CRZ) of trees which are to remain.
C. Provide, install and maintain a four (4) foot high
temporary fence around the CRZ.
D. No construction activity, storage, parking, access or
egress to the site shall occur within the critical root
zone of established trees to remain on the site. The
critical root zone is defined as a ratio of 3 feet in
diameter from the center of the trunk, for each inch of
trunk DBH (Diameter at Breast Height).
E. Tree protection fences within the critical root zone must
be completed prior to any construction. The fences must
be maintained through the entire construction period.
F. Trees which cannot be fully protected shall have a
certified aborist provide recommendations, before final
design decisions are made.
2.18 Trash Dumpster Pads
A. Trash dumpsters/dumpster pads shall be located adjacent
to, or as part of, loading dock area or receiving areas.
In the event the facility does not have a loading
dock/receiving area, the dumpster pads are to be located
in a manner that does not distract from the aesthetic
attributes of the facility and its surrounding site, but
is located relatively adjacent to the facility and in
accord with the following drequirements for placement and
configuration.
B. Trash dumpster pads shall have a concrete base and apron
designed to support an impact load of 25 tons. The pad
shall have concrete filled steel bollards for protection
and centering at rear and sides as necessary. UMCP uses
standard front-end loader dumpsters which are 8'-2" (98")
in width. The inside distance between side bollards if
they are specified, shall be a minimum of 9'-0" (108"),
but preferably 10'-0" (120"). In order to specify the
minimum width, the specifications should include a
straight path for the trash truck of at least 45'-0" feet
for trash truck access. If the trash truck must pick up
the dumpster box at any angle, rather than a direct
straight approach, then the inside distance between
bollards must be 10'-0" (120"). Also reference Section
2.13., Site Standards, Concrete Dumpster Pad, Drawing No.
14 and 15.
C. The dumpster(s) shall be accessible to building
housekeepers from the loading dock level to eliminate the
need to lift heavy trash bags above head height.
D. Trash Dumpster Siting shall address the following:
1. Do not place in proximity with:
a. Outside air intakes for mechanical ventilation
systems.
b. Other locations which may create a public
nuisance such as
- operable windows
- designated smoking areas
- food service handling areas
- lunchbreak/picnic areas
- storm drain inlets
2. Comply with Applicable Standards:
a. ASHRAE 62-1989/5.5 (Ventilation systems)
b. ICC/IMC 401.7.1 (Intake openings)
c. COMAR 26.11.06.08 (Nuisances)
d. OSHA 29CFR1910.141 (g) (2) & 29CFR1910.141 (H)
(Sanitation)
2.19 Utilities
A. New and existing demands on utilities in the building
area are to be examined. A recommendation as to
alignments and new connections are to be submitted at an
early design stage of the project. Any impact on the
capacity of the existing utilities to the on-site and
campus-wide utility network shall be brought to the
attention of the University.
B. A complete system design of all new utility extensions
from the points of the connection with existing systems
to the building site is required. This includes
establishing the precise location and size of all
underground utilities and/or services in the construction
area performing a thorough investigation of all existing
utilities, (location and capacities) in order to properly
design and locate the new utility services.
C. With the development of building details, the adequacy of
all existing utilities based on the anticipated increase
in load to serve the new construction must be determined.
If deficiencies are present, an upgrade of the
insufficient utility systems must be included in the
project's scope.
D. New and existing demand shall be coordinated with the
Department of Operations and Maintenance through DAEC to
insure that all issues are considered (adequate
capacities at tie-in points and this area of campus,
etc.). Calculations showing usage for each utility shall
be furnished.
E. The design of water and sanitary utilities are to meet
the requirements and approval of the Washington Suburban
Sanitary Commission for areas within WSSC jurisdiction.
F. The storm drainage system and components shall be
designed in accordance with Maryland State Highway
standards. Closed systems shall typically be designed
and constructed to adequately convey the ten (10) year
storm.
G. Underground Utilities
1. Primary telephone and electrical underground
utility lines shall be encased in concrete.
2. Use utility vaults for multiple use utility
trenches.
3. Place steam lines under paved surfaces where
possible.
4. Use removable concrete pavers over utility lines
where posssible.
2.20 Wetlands and Floodplain
The identification of regulated wetlands and areas within the
100 year floodplain areas within the site limits is required
in accordance with Maryland Department of the Environment
(MDE) or U.S. Army Corps of Engineers (COE) regulations and
guidelines. The identification of such areas shall be the
first priority of the site design and the existence of these
areas shall be brought to the immediate attention of the
University.
Any disturbance within a nontidal wetland or its buffer is
subject to regulation as is construction within the 100-year
floodplain. Approval from the appropriate reviewing agency(s)
is necessary for any such disturbance or construction.
