A Wetland Permit to continue the implementation of the West Nile Virus (WNV) Program was

performing mosquito control measures that focus on controlling the larvae of the two mosquito
species that are the primary vectors for WNV, Culex tarsalis and Culex pipiens. City-owned
land which contains the habitat to support the target species will be monitored and the larvicide
Bacillus thuringiensis israelensis (Bti) will be applied where the vector species have been found.
Data will also be collected on the locations of WNV occurrences on city of Boulder owned lands
for mosquitoes, birds, and mammals. The Department of Environmental Affairs will also
continue their public education and awareness program to inform the public of the need for the
control efforts and describe what the control efforts entail.

determiriation within 15 days of the date of issuance, as set forth under Subsection 9-3-9(~, by
filing a written request for appeal by April 17, 2007. The Floodplain Development Permit will
