Installation of natural gas lines and wells, electrical lines, telephone lines, petroleum pipelines and the like can alter both topography and habitat. Activities which disrupt drainage patterns, obstruct water flow or water control structures, prevent access, or leave mounded debris can cause mosquito production.
Policies For Management of Utility Construction in Marsh Areas
1. SCMAD should be notified of proposed utility construction activities in marsh areas through lead agencies or responsible parties. Such activities should be reviewed by SCMAD at both the project development phase and after the work has been completed to ensure the project is carried out in conformance with SCMAD policies.
2. Installation of utilities should not obstruct water flow or alter drainage patterns without prior notification of SCMAD.
3. Following installation of utilities the topography should be returned to original conditions. Circulation ditches or natural drainageways should drain effectively and levees and/or access roads should be put back in good repair.
4. If mosquitoes are produced as a result of negligent utility construction practices, all costs necessary to abate mosquitoes by SCMAD will be borne by the responsible agencies or property owners, pursuant to the procedures set forth in the California Health and Safety Code, Sections 2274 et. seq.
The preceding mosquito prevention criteria are intended only to ofer guidance when considering the development of design options during the planning process for projects. Be advised that these practices have been found to be effective, however, once the project has been completed it is essential that conscientious maintenance and management practices be followed to help ensure the successful prevention of mosquito production.
Be further advised that under the California Health and Safety Code (Sections 2274 et. seq.) the responsibility for the cost of mosquito control may fall on the property owner.
