Landplan Engineering, P. A.

Virginia Heights Neighborhood Improvements

Liberty, MO

Landplan Engineering was retained by the City of Liberty in September 2000 to provide surveying and engineering design for the rehabilitation of existing streets, water mains and storm drainage facilities in the Virginia Heights neighborhood. The neighborhood suffered from substandard street conditions – narrow open ditch roadways with poor vertical sight distance and drainage – as well as undersized water mains. The goal of the project was to improve roadway grades for sight distance, provide curb-and-gutter street sections with an enclosed storm sewer system to alleviate flooding problems, and increase fire flow by upsizing the older mains within the subdivision.

Landplan developed five different roadway sections with section widths varying from 22 feet to 26 feet and segments superelevated to minimize the construction limits. Once the roadway grades and sections were conceptually established, Landplan led the first of three public meetings with the City. Residents interacted with Landplan and City staff to discuss concerns such as tree preservation, flooding, easement and right-of-way acquisition, and sidewalk and retaining wall locations.

Landplan provided full plans, specifications and cost estimates for the City to bid the project. Landplan attended a pre-bid meeting, provided assistance during bidding, and attended the bid opening. Landplan provided construction assistance and final record as-built drawings at the completion of construction.
