Problems with Part 2

DRAFT

Boat Dock, Pier and Boat House Construction Standards

Problem: “Boat Dock” does not appear in the easements.

Solution: Replace with “Dock” throughout the document.

DEFINITIONS:

A. Water Use and Access Easement: the lands enclosed on one side by the lakefront property line, on a second side by the waters of Lake Worth, and on the third and fourth side by two lines, each beginning at opposite ends of the lakefront property line and each being a projection of the side lot lines of each lot as shown on the plat of record.

B. Lake Worth Management Office (LWMO): that group in the Water Department responsible for permit review and approval for improvements at Lake Worth and adjacent properties. This group is under the supervision of the Lake Worth Coordinator.

C. Boat Dock Standards Board of Adjustment (BDSBOA): a nine (9) member board appointed by the City Council to review interpretations, special exceptions and variances of the provisions of this ordinance.

Problems:

1) See above.

2) Acronym is long

Solution: Dock Standards Board of Adjustment (DSBA)

GENERAL PROVISIONS:

A. Boat docks approved under these regulations shall be for personal or family use and shall not be used for commercial activity.

B. Boat docks, piers, and boat houses shall be considered accessory structures. A primary structure must be present on the lot to which the boat dock/walkway is attached.

C. The maximum floor to area coverage allowed for boat docks, piers, boat houses and walkways shall be 25% of the area of the Water Use and Access Easement. Provided that every site regardless of the area of the Water Use and Access Easement shall be allowed a minimum coverage area of 1000 square feet and a maximum coverage area of 2500 square feet.

D. The minimum setback from a projected side yard line shall be based on the width of the property at the lakefront property line.

Lot Width Setback

Less than 50 ft. 5 ft.

50-69 ft. 10 ft.

70-99 ft. 15 ft.

100 ft. or more 20 ft.

E. Improvements may extend to a point 100 feet from the lakefront property line into the waters of Lake Worth regardless of the depth of the water at that point, or to the point at which the elevation of the land lying under Lake Worth is not greater than 584 feet above mean sea level, but in no instance to extend further than 150 feet from the lakefront property line into the waters of Lake Worth.

F. No structure shall occupy more than one third of the channel width and in no case shall extend more than 20 ft. from the centerline of the channel.

G. There will be no living quarters allowed on any boat dock, pier, boat house or walkway that extends over the lakefront property line.

Problem:

1) Ambiguous

More Appropriate: “All structures that extend over the lakefront property line shall be classified as Group U Occupancy.”

H. Enclosed structures are not allowed. In order to protect a raised boat within a dock from the elements, solid sides on the boat house will only be permitted for a maximum of two (2) feet downward to the point where the ceiling joist meets the top plate. No additional materials (i.e. lattice, fencing, bars, screen fabric, doors, glass, etc.) may be installed below the two (2) foot sidewalls.

Problems:

1) No clear and compelling reason was given as to why enclosed structures would be prohibited.

2) There was no consensus of the Dock Steering Committee to disallow enclosed structures.

3) The right to build a “boat house” was granted under the easement. The wording above attempts to revoke that right. Even though the city may now regret its former decision, property rights cannot be revoked without eminent domain proceedings and just compensation.

Solution: Remove the wording.

I. A contained storage area not exceeding 27 sq. ft. is allowed on the first floor (lower deck) of the structure for storing tackle, life jackets, etc. Products considered hazardous or which have warning labels prohibiting its use near public water supplies shall not be stored in these areas.

Problems:

1) See “H” above.

2) 27 feet is laughably small anyway.

Solution: Strike part of wording.

J. No toilet facilities of any type will be allowed on any structure built past the lakefront property line. A potable water supply can be plumbed to the first floor (lower deck) provided that required backflow prevention devices are installed and inspected in accordance with the Plumbing Code of the City of Fort Worth.

K. Fuel pumping facilities exceeding fifty-five gallons are not allowed on structures built that extend past the lakefront property line.

L. Structures shall be limited to a single story (lower deck) and a sundeck (upper deck). The floor of the lower deck shall be no less than the 596 foot elevation. The roof of a structure shall have a minimum of 6 in 12 pitch. The upper deck may not have a permanent roof or covering.

Problem:

1) The wording describes a 45’ pitch.

Correction should read: “1/2 in 12 pitch”

M. Any structure that extends more than 100 feet from the lakefront property line shall be equipped with a white photocell light of no less than 60 watts that operates continually from dawn to dusk. The LWMO may require that lighting be placed on structures less than 100 feet from the shoreline when in their opinion it is warranted to enhance boating safety. It is the dock owner’s responsibility to ensure that all required lighting is properly maintained and operational at all times.

Problem:

1) Wattage is a power usage description – not a brightness spec.

2) Modern lighting continues to provide more brightness with less electrical usage. A “traditional” 60 watt incandescent light produces ~800 lumens.

3) Boats and other vehicles successfully use much dimmer lights at night.

4) Many people don’t have electricity on the end of their docks to power bright lights.

5) Modern solar powered LED yard lighting provides a good and inexpensive solution.

Solution: “200 lumens”

Problems with Part 1

Discussion of problems have been put in yellow text.
Problems include several easement violations and severe violation of property owner privacy rights.
********************************************************

*Chapter 36; added to read as follows:


DRAFT

Chapter 36
Docks, Piers and Boathouses


DEFINITIONS:

A. “Boat Dock, Pier, or Boat House”: a structure extending from the shore into the water to permit the landing and mooring of vessels. The term “boat dock, boat house” or “dock” includes the anchoring system and any walkways or bridges that will attach to the dock itself.
Problems:
1) Definition conflicts with rights granted in easement. This document erroneously implies structures can only be used in the support of boating activities. Easement clearly states that structure can be used for water recreational activities including the storage of boats.
2) Easement uses the words “dock” but never “boat dock.”
More Appropriate: “Piers, docks, and boat houses: structures used for ingress and egress to and from Lake Worth and for water recreational purposes including the storage of boats. These terms include the anchoring system and any walkways or bridges that will attach to the dock itself.”

B. “Walkway” or “Bridge”: a passage that provides access from the land to a boat dock, marina, or other floating facility.
C. “Dead Load”: the permanent inert weight of the dock structure, including fixed or permanent attachments, such as bumpers, railings, winch stands, roof structures, etc.
D. “Decking”: the surface material that forms the floor of the boat dock or catwalk.
F. “Flotation Live Load”: the total load that a dock can carry without capsizing or sinking. The flotation live load is equal to the dead load plus the live load.
G. “Habitable Structure”: any structure on a boat dock or catwalk, whether permanent or temporary.
Problems:
1) Far too ambiguous.
2) Not needed anyway.
Solution: Remove this definition.

H. “Hunt Absorption Test”: a test documenting the rate at which flotation material absorbs liquid, as well as the quantity of liquid absorbed.
I. “Live Load”: any moving or variable superimposed load on the boat dock.
J. “Registered Professional Engineer (RPE)”: a professional engineer currently registered with the State of Texas as a professional engineer with a specialization in civil or structural engineering and experienced in boat dock and pier construction.
K. “Sanitation Device”: any enclosure or equipment used as a toilet or bathing facility,
L. “Lakefront Property Line”: the property line that borders the waters of Lake Worth.
M. “Structural Live Load”: the weight of the dock itself and its ability to support itself.
N. “Working Load Safety Factor”: the ability of a boat dock anchoring system to hold or withstand loads. A safety factor of 3.0 means the anchoring system is rated to hold or withstand a load equal to three times the entire weight of the structure; e.g., if the structure weighs 1,000 pounds, the cable attached to the anchor will be able to hold 3,000 pounds.

Terms Needing Definition:
Lake Worth Management Office (LWMO)
RPE – need to add acronym to definition

3601 Permit Required

3601.1 . No person shall erect, construct, enlarge, alter, or move any dock, pier, boathouse or combination to any body of water within the corporate limits of Fort Worth, that is under the jurisdiction and control of the City of Fort Worth, without complying with the provisions of this chapter. Persons seeking to construct a boat dock must submit to LWMO two complete sets of project plans for the dock, including the anchoring system, and any walkways or bridges that will attach to the boat dock;
(A) When a dock will use existing facilities as part of the new proposed dock, the project plans must include a complete description of the existing facilities, and those facilities must comply with the specifications set forth in these regulations.
(B) The plans must be signed and sealed by a registered professional engineer (RPE), and contain a statement that the proposed dock complies with the specifications set forth in these regulations.
(C) Each plan set also must include a copy of the manufacturer’s certified plans for any components that will be a part of a dock, such as floats, decking, railing, or awning systems.
(D) Both engineered plans and manufacturer’s certified plans must be based upon the actual conditions at the site of the proposed dock.
(E) Upon approval of the plans by the Lake Worth Management Office the plans will be taken to the Fort Worth Development Department and a building permit (missing words).
3601.2 During construction of a dock, a complete set of all permits and approvals required for construction of the dock must be posted in a readily visible location at or adjacent to the construction site, and one complete set of the approved plans must be kept available at the construction site.
3601.3 Construction of a dock must be completed within six months of the date that the permit is approved by the permitting entity.
Problems:
1) The permitting entity already provides for a time limit and extension policy.
Solution: Remove.

3601.4 After a dock is completed, an RPE must submit to the Lake Worth Management Office a signed and sealed certification that it was built in accordance with the requirements set forth in these regulations and the plans submitted to and approved by the LWMO.


3602 Use.

3602.1 Boathouses shall normally be classified as a Group U Occupancy. Other occupancies may be allowed when the use is permitted by the Zoning Ordinance, together with the approval of any other appropriate department of the City of Fort Worth, and the construction complies with this code for said use.

3603. Design and Design Loads.

3603.1 Flotation devices for docks walkways, and bridges shall be designed to support the dead load plus 30-pounds per square foot (PSF) live load applied to deck area.

(B) Bracing shall be accomplished by one or more of the following methods:

1. Cross or “X” bracing. Cross or “X” bracing may be used on each set of pier and box cribs.

2. Beams may be used as bracing, provided the connections give sufficient support to resist horizontal forces equivalent to that of cross or “X” bracing.

3. Knee bracing. Knee bracing shall be used on each pier attached to and paralleling the platform deck. Pipe knee bracing shall be a nominal 2-1/2 inch I.D.
Problems:
1) Proscribing bracing is unnecessary. The engineering requirements have already resolved the horizontal wind loads.
2) There are other bracing solutions than those listed here that would be just as viable.
3) Technology advances may provide additional solutions in the future.
Solution: Remove

3604.7 Attachment of deck. Attachment of the platform deck to beams and piles shall be accompanied by one or more of the following methods:

(A). By attaching the beams to the piles and box cribs by lag bolts.

(B). By caps: Wood caps shall be a minimum nominal 4-inch material and anchored by bolts and welded.
Problems:

2. All docks and piers shall be anchored to the shore line.

3. All anchors shall be of masonry, concrete, or steel and shall be securely fastened to the dock or pier by wire rope, cable, chain, or other approved methods.

3606. Required Water Proofing.

3606.1 All wood below one (1) foot above spillway elevation on lakes or below one (1) foot above the 50-year flood elevations on other bodies of water shall be treated lumber. Creosote is not allowed.
Problem:
1) Requires additional calculation by homeowner.
More Appropriate: “All wood below 601 elevation shall be treated lumber.”

3606.2 All metal, including bolts, lag bolts, and fasteners, shall be galvanized or painted with paints of similar materials approved for immersion in water.

3607 Flotation Material

3607.1 Flotation material shall be extruded polystyrene, expanded polystyrene, or a copolymer of polyethylene and polystyrene and shall have a minimum density of 0.9 pounds per cubic foot, and be of consistent quality throughout the float. Beads shall be firmly fused together, and there shall be no voids inside the encasement. Flotation material shall have a water rate absorption of less than 3.0 pounds per cubic foot over 7 days when tested by the Hunt Absorption Test. Other flotation material may be considered if it meets all of the requirements set forth in this section.

3607.3 Drums made of plastic, whether new or recycled, or metal shall not be used for encasements or floats.
3607.4 All floats shall be warranted for a minimum of eight years against sinking, becoming waterlogged, cracking, peeling, fragmenting, or losing beads, and shall not be prone to damage by animals.
3607. 5 Floats that are punctured, exposing the foam to erosion or deterioration, shall be replaced immediately.


3608. Boat House Construction.

3608.1 Construction of boathouses or other structures shall meet or exceed the requirements for framing and coverage as specified in other parts of this code. When, in the opinion of the Building Official, the load of the intended use exceeds the capability of the minimum construction design specified in Section 3604, plans and specification may be required to be designed by an engineer registered in the State of Texas.

3609. Inspections, Removal for Violations.

3609.1 Docks may be subject to inspection by the LWMO or its authorized agents, without notice, at reasonable times.
Problems: (Severely violates rights to privacy.)
1) Violates “exclusive use” granted by easement - “The waters of Lake Worth, except that such use shall be nonexclusive except for such piers and docks constructed thereon.”
2) Violates the Constitution of the United States which protects citizens against unlawful search and seizure.
3) The LWMO (or any citizen for that matter) may use the lake as they wish. Inspections from the lake does not need additional authority.
Solution: Remove

3609.2 Dock owners and boat docks must comply with these regulations and any requirements contained in a permit at all times.
3609.3 Failure to complete inspections, follow inspection guidelines set forth above, or to correct any violations of these rules within thirty days of receipt of written notice, may result in the division or permitting entity requiring removal of the dock at the dock owner’s expense.
Problems:
1) Gives undue authority to LWMO agent.
2) Resolution authority for violations already exists in the permitting and code inspection departments.
Solution: Remove
3609.4 The division or permitting entity may remove docks that become hazards to navigation at the dock owner’s expense.
3609.5 When a boat dock is removed for any reason whatsoever, including at the initiative of the dock owner or at the direction of the LWMO, the dock owner shall be responsible for the complete removal of the entire dock including the boat dock, walkway, anchoring system, cables, floats, and any other related components or materials installed in conjunction with the construction, maintenance, or use of the dock.
Problems:
1) Implies LWMO has sole authority to authorize removal of docks and seizure of property without due process.
Solution: Remove portion of sentence.

Docks, Piers and Boathouses

DEFINITIONS:

A. “Boat Dock, Pier, or Boat House”: a structure extending from the shore into the water to permit the landing and mooring of vessels. The term “boat dock, boat house” or “dock” includes the anchoring system and any walkways or bridges that will attach to the dock itself.

B. “Walkway” or “Bridge”: a passage that provides access from the land to a boat dock, marina, or other floating facility.

C. “Dead Load”: the permanent inert weight of the dock structure, including fixed or permanent attachments, such as bumpers, railings, winch stands, roof structures, etc.

D. “Decking”: the surface material that forms the floor of the boat dock or catwalk.

F. “Flotation Live Load”: the total load that a dock can carry without capsizing or sinking. The flotation live load is equal to the dead load plus the live load.

G. “Habitable Structure”: any structure on a boat dock or catwalk, whether permanent or temporary.

H. “Hunt Absorption Test”: a test documenting the rate at which flotation material absorbs liquid, as well as the quantity of liquid absorbed.

I. “Live Load”: any moving or variable superimposed load on the boat dock.

J. “Registered Professional Engineer”: a professional engineer currently registered with the State of Texas as a professional engineer with a specialization in civil or structural engineering and experienced in boat dock and pier construction.

K. “Sanitation Device”: any enclosure or equipment used as a toilet or bathing facility,

L. “Lakefront Property Line”: the property line that borders the waters of Lake Worth.

M. “Structural Live Load”: the weight of the dock itself and its ability to support itself.

N. “Working Load Safety Factor”: the ability of a boat dock anchoring system to hold or withstand loads. A safety factor of 3.0 means the anchoring system is rated to hold or withstand a load equal to three times the entire weight of the structure; e.g., if the structure weighs 1,000 pounds, the cable attached to the anchor will be able to hold 3,000 pounds.
