SCOPE OF WORK

PROJECT TITLE: Ste. Genevieve National Historical Park: Wilhauk and Kern Property Hazard Tree Removal

LOCATIONS: 1) Wilhauk House (Park Headquarters): 339 St. Marys Rd, Sainte Genevieve MO, 63670

2) Kern House: 19071 US-61, Sainte Genevieve, MO 63670

OVERVIEW: Hazard tree removal is needed at two separate locations within park boundaries, 1) Wilhauk House (park’s headquarters building), and 2) Kern House. A total of twenty-three (23) trees will need to be removed from these two locations – sixteen (16) trees at park headquarters, seven (7) trees at the Kern House. Each tree must be removed as close to the ground as possible. Stump grinding is not required. See Tree Maintenance Worktable for more detailed information.

The twenty-three (23) trees located at both the Wilhauk and Kern property are either dead or overhanging above a structure. Due to the location hazards, the contractor should anticipate the usage of specialty equipment, tree climbing, or additional labor to navigate and remove each identified tree. The contractor is responsible for removal of all tree materials while taking precautions to ensure that park grounds are preserved and unimpaired from equipment usage.
