Palmetto Street, Florence, SC These plans are for illustration purposes only, so the contractor can visualize the utility relocations. For detailed construction utility relocation plans, the contactor will need to coordinate with the utility owners to obtain copies. It is the responsibility of the Contractor to call SC811 and the non SC811 member utilities three (3) days prior to work so that the existing utilities can be properly marked. All utility relocation work for those who are inside the project limits will be verified and coordinated by the contractor during construction. UTILITY AS-BUILTS: The roadway contractor shall be responsible for the collection and incorporation of the utility asbuilts in their final submittal. All existing, proposed, and abandon lines must be shown. UTILITY RELOCATIONS: Santee Cooper Power (SC) (OH1/E1) (Power Distribution) Santee Cooper Power has an overhead 3-phase power line along the north side of West Broadway Street from project beginning around STA LT and continues east to the end of the project around STA LT. At STA XL and XL SC has overhead crossings towards Collins Street. The two overhead crossings connect at the pole at STA RT on Collins Street and continues south on the west side to STA RT. At STA XL on Collins Street, there is a single phase overhead crossing. At STA XL on West Broadway Street there is an overhead single phase crossing. Communication companies are attached on all legs of the SC s overhead distribution network.

3 It is intended before construction is to begin, SC will remove their overhead facilities from the pole at STA LT on West Broadway Street to pole at STA LT. SC will remove the overhead crossing at STA XL and XL. SC will remove the pole at STA RT on Collins Street. SC will install a new pole at STA LT and make a new span to the pole at STA RT on Collins Street. SC will install a new span between the poles at STA LT and STA LT. Once SC receives an approved encroachment permit, work authorization letter, and the right-of-way is staked, SC will schedule their next available crew to perform their relocations. It will take SC 2 weeks to complete the relocations. Contractor to confirm time frames and relocation status. City of Myrtle Beach Water (COMB-W) (W1) City of Myrtle Beach Water has a 10-in PVC water main that runs along the south side of West Broad Street from project beginning and continues east to STA RT where it crosses to the north side. It then continues east to the project end. This line is bored under the swash. At STA LT on Collins Street, a 6-in PVC water main branches off the 10-in water main and continues south along Collins Street on the east side to the end of the project. At STA RT on Collins Street, there is an existing fire hydrant. The 10-in water main will remain in place as is. At STA LT, the 6-in water main will need to be dropped in place to accommodate the proposed drainage. Otherwise, the 6- in water main will remain in place as is. For the 6-in water main drop, adjustment of valves, meters and services, and any unforeseen construction conflicts, the City of Myrtle Beach will need 2 weeks notice before the relocation is needed and 5 days to complete the relocation.

COMB-S has a 24-in force main that perpendicularly crosses West Broadway Street at STA XL and then continues east along West Broadway Street to the project end. This 24-in force main also continues along the west side of Collins Street from STA RT to project end. COMB-S also has a gravity system along the south side of West Broadway Street from STA RT to STA RT with a crossing at STA XL. The 24-in force main will remain in place. Special drainage structures have been designed to accommodate the 24-in force main. See the drainage plans and details. The 20-in force main will be relocated between STA LT and STA LT.

The existing force main crossing over the swash will be removed as well the piers and attached duct bank. The City of Myrtle Beach intends on completing the jack and bore of the 20-in force main under Withers Swash prior to construction beginning.

The City s contractor will perform the east crossing first. The City of Myrtle Beach will need 2 weeks to complete the crossings, tie-ins, and pier removal.
