the Facility in good working order as appropriate. In the event the City, pursuant to
this Agreement, performs work of any nature, or expends any funds in performance
of said work for labor, use of equipment, supplies, materials, and the like, the
Association, its successors and assigns, shall reimburse the City upon demand, within
thirty (30) days of receipt thereof for all reasonable costs incurred by the City
hereunder. In the event that Association or its successors or assigns fail to pay the

CITY OF FORT WORTH STORMWATER FACILITY
OPERATION AND MAINTENANCE PLAN
The only responsibility the City of Fort Worth has in the operation and maintenance of this
Facility is inspection.
General Maintenance Procedures
The structural and functional integrity of the Facility shall be maintained at all times by
removing and preventing drainage interference, obstructions, blockages, or other adverse
effects into, through, or out of the system.
Periodic silt removal shall occur when standing water conditions occur or the pond's storage
volume is reduced by more than 10%. Silt shall be removed, and the pondibasin returned
to original lines and grades shown on the approved engineering plans. In addition,
corrective measures are required any time a basin does not drain completely within 72 hours
of cessation of inflow. NO STANDING WATER IS ALLOWED in basins designed for
dry detention purposes.
Accumulated litter, sediment, and debris shall be removed every 6 months or as necessary
to maintain proper operation of the basin. Disposal shall be in accordance with federal, state
and local regulations.
Detention facilities shall be mowed monthly between the months of April and October or
anytime vegetation exceeds 12-inches in height.
To prevent debris from entering and clogging the downstream storm sewer system a wire
mesh screen or similar screening device shall be installed over the outlet until final
acceptance.
4. PREVENTIVE MAINTENANCE/INSPECTION
Visual inspections of all components will be conducted every 6 months.
A log shall be kept of maintenance actions, and inspections. The log should
document the condition of the detention system's primary components, mowing, and
silt, litter and debris removal dates. Document aeration of the basin bottoms and
replanting to prevent the sealing of the basin bottom.
Written maintenance and repair records shall be maintained by the party or
parties signing the attached Agreement and shall be provided to the City upon
request.

OPERATION & MAINTENANCE - GABION
1. INTRODUCTION
PHI GROUP
A KELLER COMPANY
The Gabion retaining wall system comprises steel welded mesh cages coated with specific anti corrosion treatment,
laced together and filled with granular material to the specified grading to form a gravity structure built such that
the weight of the wall resists the pressures exerted on it from the ground behind. The depth of the structure will
increase with the height of the wall.
Materials used:-
Gabion Cages: Steel Welded Mesh Cages with Alu-Zinc/PVC Coating
Fill to the structure: Type 6G gabion infill stone
Foundation: Compacted Type 1 granular sub -base
2. PHI GROUP DESIGN DRAWINGS
Issued to suit project
3. CONSTRUCTION METHODS
The Gabion retaining wall has been general installed as the details on this page. For more specific project details
please refer to the project Specific Works Package Plan.
4. MAINTENANCE PROCEDURES
Any long term maintenance is basically periodic visual inspections to detect damage or abnormalities. Any damage
detected should be reported and advice on repair should be sought from Phi Group. These would typically be
annually, but will vary depending on the location of the wall and what it is supporting.
Abnormalities may include: localised bulging of the face; broken components; damage by impact or vandalism;
vegetation on the face; excessive water through the face.
No requirement for any cleaning is anticipated.
If any fencing has been installed at the top of the wall to prevent falls, this will need to be inspected to ensure it
remains adequate. Typically any fencing will not last as long as the structure and will need to be replaced during the
lifespan of the retaining wall.
If a rear of wall drain has been installed at the construction stage, the relevant catch pit, manhole or soak away
within the development should be checked annually to ensure this can still flow.
5. POINTS TO BE AWARE OF
5.1 Local minor impact damage
Individual split, broken or damaged cage components will not affect the structural capacity of the wall and can be
repaired locally if required. If several components are broken in the same area such that it will affect other parts of
the wall or loss of the infill stone, advice should be sought from Phi Group or a structural Engineer.
5.2 Major collision damage
As with any structure, affected areas may require re -building with localised support of the fill behind. Advice should
be sought from Phi Group or a structural Engineer.
5.3 Settlement
The "method compaction" guidance within Specification for Highways Works; Series 500 is based upon achieving
90% compaction. It follows that some post -construction consolidation should be expected. The Gabion system is also
a flexible structure that can accommodate differential settlement caused by seasonal moisture changes, so some
minor movements will occur over its lifespan.
5.4 Excavation near the wall
Excavation behind the retaining wall may affect the structure but it will be based on how close and to what depth
the excavation is carried out. Also the plant used to carry out the excavation can damage and exert large loadings on
the wall. If any excavations are required behind the wall advice should be sought from Phi Group first. Excavation in
front of the wall may undermine the structure. Any excavation deeper than 500mm may have the potential to
undermine the retaining wall foundations leading to settlement and possible collapse. Any excavation in front of the
wall should be checked by a structural Engineer or further advice sought from Phi Group
5.5 Vegetation
The Gabion system is a caged structure filled with inert crushed stone, so it is not expected to be susceptible to
vegetation establishment from within the wall. Vegetation growing on or up the face of the wall will not affect the
structure. However, any vegetation growing out of the wall/cages should be removed.
5.6 Water
The Gabion retaining wall has crushed stone within and behind the wall, thus the wall should have very little
evidence of water within it. If water is coming through the face this would mean excessive water is coming from
behind the structure and should be investigated to find the water source and remove it. For more specific project
details please refer to the project specific drawings.
6. DEMOLITION AND DISMANTLING
No demolition should be undertaken without reference to Phi Group or a Structural Engineer.
7. RESIDUAL RISKS
As any other type of retaining wall, falling from height is a residual risk of a Gabion retaining wall. When Phi Group
installs a retaining wall it will normally have a fence already built in to the top of the wall. Occasionally post formers
will be left in the top of the wall for the Main Contractor to install a fence after our works are complete. This will
ensure that falling from height from the top of the wall has been addressed, but the fencing will need to be
maintained for the lifespan of the wall. Gabion walls can be climbed by people and thus falling from height off the
wall may also be an issue. The Contractor will need to take any necessary steps to bring this to the end -users
attention.
