Study: Ivy Meadows, Parker's Place need $2.75 million in road and storm upgrades before development
Summary
City Engineer Boyd Davis told the Planning Commission that preliminary impact studies for Ivy Meadows and Parker's Place show about $550,000 in road widening and roughly $2.2 million in storm-drain improvements are needed to support proposed development; developers would build improvements with potential reimbursement via impact fees.
City Engineer Boyd Davis presented the Planning Commission with results of infrastructure studies for the newly annexed Ivy Meadows and Parker's Place areas, concluding that both road and stormwater work will be required before development.
Davis said the traffic study modeled conditions through 2050 under a "no build" scenario and found that while road capacity would be adequate, three road segments were too narrow and had only about 10 years of pavement life. "The recommendation was to widen each road to 26 feet, include a three-foot shoulder, and apply a full asphalt overlay," he said. Estimated widening costs were about $226,000 for segment four, $86,000 for segment five and $210,000 for segment eight, for a total in the neighborhood of $550,000.
On drainage, Davis summarized a consultant inventory that showed some existing storm pipes operating at capacity and projected new over-capacity conditions once development occurs. Full upsizing of pipes was impractical in places; a balanced approach using detention ponds holding to a reduced release rate of 0.1 cubic feet per second per acre was recommended so most main trunk lines could remain while select segments would be upsized to 36 inches. He said estimated storm improvements were about $835,000 for the Ivy Meadows eastern system and $1.3 million for the Parker's Place western system.
Davis told commissioners that the initial construction costs would fall to developers and that impact fees collected by the city could reimburse developers over time. He also noted that the right-of-way already exists as 66 feet wide, so no additional land acquisition was expected, but that actual construction costs could be higher when built due to inflation.
The presentation closed with next steps: further coordination with the county and developers, refining cost-sharing, performing an impact-fee study, and preparing reimbursement agreements to be considered by the City Council.
Davis emphasized the study focused on main trunk infrastructure and did not resolve localized backyard drainage, which will be addressed by developers during final design.
