What to Expect During Construction
The contractor will develop detailed traffic control plans before construction begins. You can expect the following activities and impacts during construction:
- Noise, Vibration, and Dust: Construction creates noise, vibration, and dust and disrupts normal neighborhood activity.
- Equipment Storage: Equipment and materials may be stored on streets overnight.
- No Parking: Little or no on‐street parking will be allowed in and near work zones, especially during work hours. On days when crews will be working in front of your house or nearby, please plan ahead. If you park your vehicle on the street, plan to move it off the street by 7 a.m. and return it at 6 p.m.
- Traffic Delays: Expect traffic delays in and near the work area.
- Services Maintained: Sewer, water, and other utilities are expected to remain in service during construction.
- Garbage Pickup: Access to garbage and recycling bins for haulers will always be maintained.

Safety Around Construction
Safety is our top priority for the public and our crews. Please use caution and stay outside of the work zone. If you need to get the attention of a crew member, please do so from the sidewalk or contact Joe Tursi, the community outreach representative for the project. We understand that construction can have many impacts on people living and working in the area, and we appreciate your patience and understanding while we perform this necessary sewer work.
Open Trench Excavation will be necessary to install the new sewer extensions and sewer service laterals to adjacent properties. It consists of excavating down to the required depth for the sewer system, installing the new pipe, then backfilling the trench, and completing final pavement restoration of the trench after the work passes inspections.
How to prepare for construction
If you have a concern about any items or features inside your house or other structures that you think might be vulnerable to construction vibration, we recommend that you secure them before construction begins at your property. Secure hanging items like photos, china dishes, or ceramics, or remove them temporarily before construction begins. Items on shelves may rattle and move, so take precautions you think are necessary. We also recommend that you take photos and/or videos to document pre-existing conditions inside your house, including existing cracks on ceilings, walls, and floors. Be sure photos and videos are date-and-time-stamped for verification.
On-Street Parking—Please Plan Ahead
The city’s contractor for this project has posted NO PARKING signs in and around areas where crews are working and staging equipment and materials. On days when crews will be working in front of your house, nearby, or where you park your vehicles on the street, please plan ahead. Plan to move your vehicles off the street by 7 a.m. and return them at 6 p.m. Monday through Friday. Keeping your vehicles parked on the street puts them at risk of being towed, delays the work, and extends the inconvenience. Thank you for your cooperation.
If you know that you will be away from home for an extended period, such as a week or two, please plan ahead and arrange to store your vehicles off the street if possible. You may also check in about the tentative schedule for construction on your street to avoid conflicts. We want to make sure that you keep your vehicles safe and that our crews can do their work. Thank you.
We Want to Hear from You
Please let us know if you have a concern or question about the project. Be sure to include your name, property address, and project name (NWSE) in your voicemail and email so we can provide you more details about what to expect in front of your property. Also, please write “NWSE” in the subject line of your email.
Environmental Services will be working with our contractor to do all we can to minimize construction impacts on the neighborhood. Construction is noisy, dusty, and causes vibration. It will be disruptive.
