Only a Professional Land Surveyor should be relied upon for final determination of any specific boundary. There are two known areas which are disputed. One is the boundary along Ramsey Road between Fairfield and unincorporated Solano County. The second area is south of Illinois Street in Fairfield.</span></p> <table border="1"> <tbody><tr> <th>Field</th> <th>Description</th> </tr> <tr> <td>Name</td> <td>City Name</td> </tr> <tr> <td>Agency</td> <td>Proper City Name</td> </tr> </tbody></table> <p><span>Date last updated: 05/22/2024 - Resolved geometry at City of Vallejo and City of Benicia northwestern edge</span></p> <p><span>Uploaded to Solano County GIS Portal 05/22/2024 by GIS Services Team, Solano County Department of Information Technology</span></p> <p><span></span></p> </div> </div></div>
