Delaware County Commissioners approved a list of construction projects for the engineer’s office and sewer district this week.

Commissioners approved bids Monday for construction materials used by the county engineer’s office.

“We use a number of different maintenance materials throughout the year including stone aggregate,”said Rob Riley, chief deputy engineer. “We bid out those three services to contractors to assist us through out the year.”

Riley said the engineer’s office did receive bids from multiple vendors for each contract.

“What we’re asking you to do is award non-exclusive bids to each contractor so we can first go to the lowest bidder,” Riley said. “Then if they are out of the material the we can go to the next lowest vendor.”

Commissioners approved all bids.

Riley asked the commissioners to declare the necessity of a traffic signal at the intersection of of Worthington Road and Highland Lakes Avenue. He said he thought the engineer’s office had done a previous traffic study for the road.

“We were aware of the IKEA Way construction,”Riley said. “We knew the traffic projections from that indicated Worthington Road would see more traffic.”

Commissioners approved it and authorized the county engineer’s office to advertise for bids on the project.

The engineer’s office also asked for the commissioners’ approval of a custom map agreement with GIS Cartography and Publishing Service for 18,650 of the county at a cost of $14,174.

Riley told commissioners it is the map that is given out from the engineer’s office to the townships and the county map department.

Commissioners approved the agreement.

Riley also sought the approval for three standard drainage petitions for the developments of Verizon Wireless located at 9110 Bunker Lane in Liberty Township, the Villas at Loch Lomand and Green Lawn Specialists located off of 774 Peachblow Road in Berlin Township.

Commissioners approved the petitions.

On Thursday Mike Frommer, executive director Regional Sewer District, sought approval from commissioners for projects.

• Approval of a change order for Metro Development II LLC and Trucco Construction Company Inc. for the Clark-Shaw sewer line.

• Approval of amendment number two for sewer improvement plan and subdivider’s agreement for Liberty Trace.

Afterwards Commissioner Gary Merrell brought up some complaints the board had received. He asked Frommer if things had “been resolved and everyone on the same page.”

Recently a development at Price Farms, the condominium section, “started blasting for construction,” Frommer said. “It got the neighbors a little concerned when you have the blasting occur.”

Frommer said the developer at the sight is developing a Facebook site to help.

“They’re doing a siren that goes off before the blasting occurs,” he said. “It’s been some reactive work, but we’ve gotten to the place we need to be on those developments.”

Frommer told commissioners the projects are estimated to be completed in the first quarter of 2018.

“A lot of it just depends on the production and the rock,” Frommer said. “It can really throw stuff.”
