General Stormwatar Management Mosquito Control BMPs • Ensure Mosquito Control Agencies have access to infrastructure Co inspect or make appropriate treatments when necessary. • Manage sprinkler and irrigation systems to minimize runoff entering stormwatar infrastructure. •Avoid intentionally running water into stormwatar systems by not washing sidewalks and driveways,washing care on stre¢ts or driveways, etc. • Inap¢ct facilities wa¢kly during warm weather for the presence of standing water or immature mosquitoes. -Remove emergent vegetation and debris from gutters anO channels that accumulate water. -Consider mosquito production during the design, construction, and maintenance of stormwatar infrastructure. • Oasign and maintain systems to fully discharge capturetl water In 96 hours or lass. - Include access for maintenance in system tlesign. • Design systema with permanent water sources such as wetlands, ponds,sumps, and basins to minimize moaqulto habitat and plan for routine larval mosquito inspection and control activities with the assistance of a local moaq uito control program. Stormwatar Treatment Ponds and Constructed Treatment Wetlands -Whenever possible, stock stortnwater ponds and constructed wetlands with mosquito-eating fish available from local moaqulto control progrems. - Design and maintain accessible shorelines to allow for periodic malntenanca and/or control of amerg¢nY and shor¢line vegetation, and routine monitoring and control of mosquitoes. Emergent plant density should ba routinely managed so mosquito predators can move throughout th¢vegetated areas and era not excluded from pond edges. •Whenever possible, design and maintain deep zonas in excess of four feat(1.2 m)to limit the spread of invasive emergent vegetation such as cattails.Tha adg¢s below the water surtaca should ba as steep as practicable antl uniform Yo discourage dense plant growth that may provide immature mosquitoes with refuge from pretlators and increased nutrient availability. - Usa concrete or liners in shallow areas to discourage plant growth where vegetation Ia not necessary. •Whenever possibl¢, provide a mans for easy dewatering if Headed. - Manage the spread and density of floating and submerged vegetation that encourages mosquito production (i.e., water hyacinth, water primrose, parrot's feather, duckweed, and filamentous algal mats). • If possible, compertmantaliza managed treatment wetlands so the maximum width of ponds dcas not axca¢d two Limas the effec[Iva distance(40 feat[12 m]) of land-based application technologies for mosquito control agents RBfarBnCO: aa0t MH0090TBnt P�acticBH fof MBHgYIto Control In CBIHomla(July 2at1) vector�o.nH oIHHHSH semon Call(arnle OBpp�Vnant oT Public HBBItb loll .
