A ',combination of regulations, arid construction of
protective 'works24 is often desirable for areas used as'

building sites. Regulations can control construction of

groins, jetties, and other works placed in waters to assure

they will not increase eros ion. damage to other lands.

Regulations can also control dredging, mining alteration of

dunes or beaches, or other activities which may destroy

natural protective barriers. zoning, subdivision regulations,

building codes and other special regulations can restrict

uses' in areas of wave' and erosion damage potential and require

minimum protection elevations at other sites, Use of these

regulations is discussed at greater length in Chapter III,

In cornbination with the regulations, protective .,orks such,

as groins, sea,valls, bulkheads and levees can be, used to

reduce wave action and control erosion, Active management

progra..Tfis, slich as artificial replenishment of beaches with

offshore sands, to preserve natural protective beaches will,
in many instances" be essential.

A community land use plan incorporating coastal ,zone

management can suggest the most appropriate combination of

regulation and protective works. Often a range of techniques

Selection of a particular combination will depend upon the

total land use needs of the community and overall planning
goals.
