other recommendations identified within the CSAP. As discussed in the CSAP, the other
recommendations build on the implementation of the 5th and 6th Streets Conversion Project.
II. SCOPE OF SERVICES

application graphics and map(s) (as needed), update required forms, coordinate with the City on
an updated letter of support template to send to elected officials, other sponsors and community
supporters of the Project, coordinate with the City on a local match funding commitment
letter, and provide general assistance with the submission process.
ATS will coordinate the grant application's development with the City team to verify required materials
are obtained and that aspects of project delivery are efficiently and effectively communicated. Weekly
coordination meetings will be supplemented by ad hoc communication between ATS and the
