Page 5 of 7 <br />Exhibit B <br /> <br /> <br /> <br /> <br />Question 14: Section 3.03.3 Street Cuts and Restoration – Asphalt Cement Concrete <br />Pavement, is there a way to provide compaction testing on every project instead of requesting <br />an exception to the CLSM backfill requirement? <br /> <br />Finding: There is an exception process for allowing granular backfill in place of CLSM. If a <br />permittee (utility) would like to receive blanket approval for granular backfill in conjunction with <br />compaction testing as a standard operating procedure, a blanket exception could be <br />considered. Requests for a blanket exception should be submitted to the Public Works <br />Maintenance Surface Technical Supervisor for consideration. The exception may be approved, <br />approved with conditions or denied based on the merits of the request. <br /> <br /> <br />Question 15: Section 3.03.3 Street Cuts and Restoration – Asphalt Cement Concrete <br />Pavement, the part referencing trench compaction is confusing. Is CLSM required or is granular <br />backfill allowed with testing, and could testing be provided on every project instead of <br />requesting an exception on every project? <br /> <br />Finding: There is an exception process for allowing granular backfill in place of CLSM. If a <br />permittee (utility) would like to receive blanket approval for granular backfill in conjunction with <br />compaction testing as a standard operating procedure, a blanket exception could be <br />considered. Requests for a blanket exception should be submitted to the Public Works <br />Maintenance Surface Technical Supervisor for consideration. The exception may be approved, <br />approved with conditions or denied based on the merits of the request. <br /> <br /> <br />Question 16: Section 3.03.3 Street Cuts and Restoration – Asphalt Cement Concrete <br />Pavement, regarding temporary trench surfacing requirements at the end of day. Is there a way <br />rock backfill could be left 1” low on some local and low traffic roads instead of temporary <br />coldmix, which could save time and money? <br /> <br />Finding: This section, along with EC7.307, requires a temporary hard surface be installed and <br />maintained on any vehicle, bicycle, or pedestrian travel lane the same day of trench backfill. <br /> <br />There may be some locations, like a parking bay that could be protected where a temporary <br />hard surface may not be required for a short period of time when construction is actively <br />underway. The Utility Inspector has the authority to determine when and where a temporary <br />hard surface is not necessary outside of the travel lane. <br /> <br /> <br />Question 17: 3.03.4 Street Cuts and Restoration – Temporary Trench Patching and Permanent <br />Trench Restoration, does this section imply that a trench in a parking area can be left open or <br />graveled? <br /> <br />Finding: There are some areas within the public way where temporary trench patching may not <br />be necessary or required, and a parking bay that could be protected during active construction <br />may be an example. The Utility Inspector has the authority to determine when and where a <br />temporary hard surface is not necessary outside of the travel lane.
