It is the intent of the dune construction standards to regulate activities associated with the construction of dwellings or commercial buildings, where permitted, in dune areas in order to minimize damage to the dune forms and to adjacent property. The following sections shall apply to developments in dune areas.
(Ord. 24-05, 6/5/2024)
Before a building permit is issued for the construction of a dwelling or commercial building which involves the removal of vegetation in areas of sand soils, a satisfactory wind erosion prevention plan shall be submitted to the city manager. The plan shall provide for temporary and permanent sand stabilization. The plan shall return the area to its original level of stability or further increase the area's stability. This plan can be a report indicating what types of vegetation will be planted, approximately when planting will occur, how vegetation will be preserved, and other relevant techniques being used to prevent wind erosion.
(Ord. 24-05, 6/5/2024)
Removal of vegetation in areas of sandy soils shall be kept to the minimum required for building placement or other valid purposes. Removal of vegetation shall not occur more than 30 days prior to grading or construction. Permanent revegetation shall be started on the site as soon as practical.
(Ord. 24-05, 6/5/2024)
Sand removal shall be limited to that necessary for construction of permitted structures on the site or for eliminating hazards identified in the wind erosion prevention plan. Adequate consideration shall be given to removing sand from the least sensitive locations. Disturbed areas shall be properly revegetated unless building is done thereon.
(Ord. 24-05, 6/5/2024)
Site specific investigations by a registered geologist shall be required prior to the issuance of a building permit in open sand areas, property with slopes of 20 percent or more or other sites which the manager determines may have significant potential for wind erosion or other hazards. The report shall include the history of erosion or other hazards in the vicinity of the site, a map of areas in the vicinity of the site with recent evidence of erosion, a presentation of potential adverse effects of the development, recommendations on where structures should be located, suggestions on the type of protection required for the proposed use and nearby property, and other material required by the manager.
(Ord. 24-05, 6/5/2024)
The city manager may require that the developer post a performance bond to insure that safeguards recommended by either the wind erosion plan or the site investigation are provided or implemented.
