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:
Docks, Piers and Boathouses
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;

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.
