Golden Gem Estates site plan clears initial review; lift-station and roadway tie-ins remain
Summary
The 65-lot Golden Gem Estates subdivision was reviewed; planners expect minor comments and coordination with Kimley-Horn for a left-turn lane on Golden Gem Road, and developers and public works continue discussions about upsizing 6-inch to 12-inch water mains and lift-station pressures.
The Development Review Committee heard a construction-site presentation on April 30 for Golden Gem Estates, a 65-lot subdivision at the northwest corner of Golden Gem Road and Trestle Trail.
Jeff Summit of Summit Engineering represented the applicant and said planning comments were minor. "It's pretty minor comments from planning," Summit told the committee. Staff confirmed they had not yet received public-services comments and that finalized plans could be prepared for signatures after outstanding comments were addressed offline.
Discussion focused on roadway connections and wastewater-lift-station design. The project ties into existing neighborhood streets to the north and west and will be interconnected with nearby developments; Kimley-Horn is incorporating an entrance left-turn lane into its Golden Gem Road widening design, staff said. The DRC also discussed whether lift-station connection pressures should be sized to recent field readings or to the original master-plan numbers. A developer representative said field readings near the site currently measure about 45 PSI, but designing pumps to that higher pressure could force large pump installs that would later run inefficiently once upstream upsizing is completed. Public works staff said upsizing the remaining 3,000 feet of main from 6 to 12 inches would resolve the issue and that they were pursuing agreements with adjacent developments to accelerate the upsizing.
City staff asked the applicant to confirm lift-station pressures and coordinate with public works; staff said they hoped to resolve the upsizing arrangements by the end of the year. No formal DRC objections were recorded; plan signatures will follow resolution of outstanding public-services and utility issues.
