The Edmond City Council approved a $31,400 budget amendment to advance the Charles E. Lamb Nature Preserve expansion at Hafer Park.

Brad Rainey, parks and recreation director, said construction documents are about 65% complete and the city needs funds to clear access for geotechnical work on a bridge crossing Spring Creek. Rainey said the project is expected to receive a Land and Water Conservation Fund federal grant of approximately $800,000 that would match city funds already set aside.

Rainey explained part of the requested funds will be used to clear a path to enable trucks to reach the geotechnical work area and to satisfy cultural resource-survey requirements tied to the federal grant application. The council approved the transfer from special parks-tax reserves to the project budget, 5-0.

Rainey said if the grant agreement is finalized the city will proceed to complete construction documents and advance to construction once the match and required surveys are completed.
