I offer the following comments for your consideration: <br />1. Connection of the driveway serving the two new lots will need to be reviewed in relation to the <br />existing driveway for 1003 Wildhurst Trail. <br />2. Connection to the municipal sanitary sewer system is available from Wildhurst Trail. These lots <br />should be required to connect to this system, in lieu of using on-site septic systems. A manhole <br />installed for 1003 Wildhurst Trail may facilitate a short distance to connect to the system. <br />3. Wildhurst Trail was improved in 2018. Connection of the new driveway will need to be <br />coordinated with the current drainage layout. <br />4. Drainage and Utility Easements must be provided as follows: <br />a. Over all sanitary main serving multiple lots. <br />b. Over all wetlands, creeks, and buffers. <br />c. Over all pipes, swales, and ditches providing a drainage path for multiple properties. <br />d. 5' along all side lot lines, unless adjacent to Development boundary. <br />e. 10' along all front lot lines, rear lot lines, and adjacent to Development boundary. <br />If you have any questions or comments, please contact me to discuss. <br />Sincerely, <br />Bolton & Menk, Inc. <br />j�zc-�4g "4 <br />Robert E.
