Summary
Wilmington requires a license from the city before anyone builds, extends, or repairs a wharf, pier, or dock structure along the Christina or Delaware River waterfront.
Whenever any person or persons shall desire to construct, extend, alter, improve or repair any wharf or other building in the nature of a wharf, pier or other harbor structure, situate within the city, such person or persons shall make application to the board of harbor commissioners, in writing, stating the nature and extent of such proposed structure...If such proposed structure...will encroach upon the waterway, the board shall give notice of a public hearing thereon...the board shall give its assent thereto, and issue a license or permit therefor.

Full Breakdown
Under City Code § 5-27, anyone wanting to construct, extend, alter, improve, or repair a wharf, pier, or other harbor structure must file a written application with plans, specifications, and proof of title with the city's harbor authority (now the Department of Commerce, per Charter § A-101). If the structure would encroach on the waterway, the board must hold a public hearing, advertised twice weekly for two weeks, before it can approve and issue the license. Minor repairs of $100 or less that don't affect structural stability are exempt.
Violations & Fines
Building a wharf, pier, dock, or bulkhead without the license is deemed a public nuisance under § 5-29. Conviction carries a fine of $100 to $1,000, up to six months imprisonment, or both, and the sheriff can be ordered to abate (remove) the unlicensed structure.
