Sewer pipe cleaning on 2nd Ave between Thomas St and Harrison St is nearing completion. Proper staffing and safety measures are in place.
South Parcel (south of Pottery Northwest) – Horizontal boring of the tunnel, excavation, lagging and tiebacks will continue over the next several months.
SDCI has granted a TNV that permits the extension of non-impact construction activity within the South Parcel seven days per week during the windows of 10 pm – 7 am (10 pm – 9 am on weekends and holidays). The South Parcel TNV has been issued for work through Monday, June 22nd.
Conditions set by SDCI for the South Parcel TNV are as follows:
- Construction of 12-foot noise barrier around perimeter of South Parcel
- Limit impact work such as auger shaking, jack hammering, hoe ram use, or vibratory compacting to the hours allowed by SMC 25.08.425.C;
- Use drilling methods vs impact driving for shoring (i.e., soldier pile walls) and pier installation;
- Prohibit concrete saws during nighttime hours;
- lieu of pure-tone, mobile equipment backup alarms, use strobe warning lights or flaggers when possible. When strobe warning lights or flaggers not feasible, construction contractor will use broadband backup alarms. Also, create site logistics that minimize need for mobile equipment to reverse;
- Prohibit compression brakes;
- Construct enclosures around stationary equipment;
- Perform particularly noisy operations during daytime hours or schedule several noisy operations concurrently rather than separately;
- Employ time constraints for noisy operations to reduce potential impacts during sensitive time periods;
- Provide training to supervisors to increase awareness of construction noise as it relates to the noise-sensitive surrounding;
- Use properly sized and maintained mufflers, and if feasible, engine intake silencers and engine enclosures;
- Turn off idle equipment after no more than five minutes;
- To reduce noise during loading of soils with cobble, employ one of the following mitigation measures if deemed necessary:
- Line tuck beds with rubberized noise-absorbing material. Load large cobble using progressive link excavator buckets or similar and ensure loading is performed by a skilled operator or alternatively;
- Carefully load truck beds first with soils or fine gravels followed by larger pieces of cobble using excavator with progressive link excavator buckets or similar;
- Installation of a 24-hour construction noise monitoring system to log construction site noise.
- An additional Noise Monitoring Terminal, NMT4, has been placed on roof of Avalon Cooperative, a 3-story building located at northwest corner of 1st Ave N and John St.
