316.2 Turf and Landscape Irrigation (Appendix F)

Appendix F
PART 1: GENERAL
C. Preconstruction Submittals.
1. Plans or Drawings.

c. Sprinkler layout may be modified to adjust for field conditions, provided it complies with Part VI, Section B. subsection 1 Sprinkler
layout and spacing. Prior to final inspection, the contractor shall submit a letter or as-built drawing that reflects the modifications to the
authority with jurisdiction.

PART II DESIGN CRITERIA
F. Pipelines.
Pipelines will be sized to limit pressure variations so that the working pressure at all points in the irrigation system will be in the range
required for uniform water application. Velocities will be kept to shall not exceed 5 feet (1524 mm) per second.

PART V: INSTALLATION

A. Pipe Installation.
5. The trench bottom must be uniform, free of debris, and of sufficient width to properly place pipe and support it over its entire length.
Native excavated material may be used to backfill the pipe trench. However, the initial backfill material to 6 above the top of the pipe
shall be free from rocks or stones larger than 1-inch in diameter. The final backfill material shall be free of rock or debris that is
greater than 3 in diameter. At the time of placement, the moisture content of the material shall be such that the required degree of
compaction can be obtained with the backfill method to be used. Blocking or mounding shall not be used to bring the pipe to final grade.

PART V: INSTALLATION

A. Pipe Installation.

a. Vehicle Traffic Areas.
Pipe Size (inches) Depth of Cover (inches)
½- 2½ 18-24
3-5 24 - 30
6 and larger 30- 36
b. Nontraffic and Noncultivated Areas.

Pipe Size (inches) Depth of Cover (inches)
½ - 1¼ 6-12
1½ - 2 12 - 18
½ - 3 18 - 24
4 and larger 24 - 36
c. Residential single lot installations only.




c. Residential single lot installations only.
Pipe Size (inches) Depth of Cover* (inches)
½ - 1
Adopted Appendix F

Pipe Size (inches) Depth of Cover* (inches)
½ - 1 4 - 6
1¼ - 1½ 8 - 12
2 - 2½ 12 - 18
3 and larger 24
* Except in areas where more than one lot is connected together, controlled, or connected through a master
system than the depths in Chart B shall apply.

FOR ALL AREAS EXCEPT VEHICLE TRAFFIC:

Pipe Diameter Minimum depth of Cover
½ through 1 ½ 6
2 through 3 12
4 through 6 18
more than 6 24

VEHICLE TRAFFIC AREAS SHALL REQUIRE A MINIMUM DEPTH OF COVER OF 18.


6. Pipe sleeves must be used to protect pipes or wires installed under pavement or roadways, or when position of irrigation pipes or wires
conflict with pipes or appurtenances of other trades. Use pipe sleeves two pipe sizes larger than the carrier pipe or twice the diameter
of the wire bundle to be placed under the paving or roadway, and extending a minimum of 3 feet beyond the paved area or as required by
the Florida Department of Transportation (FDOT). Use sleeve pipe with wall thickness at least equal to the thickness of schedule 40 or
PR 160 pipe, whichever is thicker. Proper backfill and compaction procedures should be followed.

PART VI: TESTING & INSPECTIONS

B. Rough Inspections. Rough inspections will be performed throughout the duration of the installation. These inspections will be made by
the governing agency to ensure that the installation is in compliance with the design intent, specifications, and the Irrigation Codes .
Inspections will be made on the following items at the discretion of the governing agency:

1. Sprinkler Layout and Spacing: This inspection will verify that the irrigation system design is accurately installed in the field. It will
also provide for 3 alteration or modification of the system to meet field conditions. To pass this inspection, sprinkler/emitter spacing
should be within ± 5 percent of the design spacing.

2. Pipe Installation Depth: All pipes in the system shall be installed to depths as previously described in this code.

3. Open Trench Inspection: The trench at all joints and every transition in pipe size, will be open where open trench inspection is required.

Test all mainlines upstream of the zone valves for projects other than single family residences, as follows:
a. Fill the completely installed pipeline slowly with water to expel air. Allow the pipe to sit full of water for 24 hours to dissolve remaining
trapped air.
b. Using a metering pump, elevate the water pressure to the maximum static

supply pressure expected as specified by the design
professional and hold there for a period of 2 hours. Solvent-weld pipe connections shall have no leakage.


d. Use the following formulas to determine the maximum allowable leakage
limit of gasketed pipe.
DUCTILE IRON:
L = S D P(square root of P)/133,200
PVC, GASKETED JOINT:
L NDP (S
t f P)

Test all mainlines upstream of the zone valves as follows:
d. Use the following formulas to determine the maximum allowable leakage limit of gasketed pipe.

DUCTILE IRON:

L = S D P( square root of P ) /133,200

PVC, GASKETED JOINT:

L = NDP (Square root of P)

FLORIDA BUILDING CODE 2004 - BUILDING
AMEND EXISTING SECTION

1609.3 Determination of Wind Speeds

1609.3 Basic wind speed. The basic wind speed in miles per hour, for the development of wind loads, shall be determined from Figure
1609. Basic wind speed for the special wind regions indicated, near mountainous terrain and near gorges shall be in accordance with local
jurisdiction requirements. The exact location of wind speed lines shall be established by local ordinance using recognized physical
landmarks such as major roads, canals, rivers and lake shores, wherever possible. Pinellas County properties seaward of the Intercoastal
Waterway, including Tierra Verde and Ft. Desoto or any other areas seaward, are defined at the 130 mph/3 second gust and properties
landward of the Intercoastal Waterway are defined at 123 mph/3 second gust.

Local Conditions and Need: This amendment redefines Pinellas Countys established basic wind speed designations.

Fiscal Impact Statement: There is no change to Pinellas Countys wind speeds, therefore no cost impact associated with this amendment.

Effective Date: Effective date of Florida Building Code 2004 Building.

(a) GENERAL. Metal raceway, cable trays, cable armor, cable sheath, enclosures, frames, fittings, and other metal noncurrent-carrying
parts that are to serve as grounding conductors with the use of supplementary equipment grounding conductors shall be effectively
bonded where necessary to assure electrical continuity and the capacity to conduct safely any fault current likely to be imposed on them.
Any nonconductive paint, enamel, or similar coating shall be removed at threads, contact points, and contact surfaces or be connected by
means of fittings so designed as to make such removal unnecessary. All raceways shall contain an equipment-grounding conductor sized in
accordance with Table 250.122.

Local Conditions and Need: Amendment assures a positive return path for faults.

Fiscal Impact Statement: Minimal cost impact since this requirement has been in effect in Pinellas County since 1987.
