| IRS990/Desc | 0 | See Schedule OPark Management: The Memorial Park Development Agreement passed by Houston City Council shifted management and operations of 1,100 acres from City of Houston Parks and Recreation Department to MPC beginning February 1, 2016. To meet the demands of this new management agreement, the Conservancy incurred large start-up costs to purchase equipment, materials, and supplies and to nearly double staff and contractors. Park management software was purchased to improve staff efficiency, customer service and to track productivity; a new cloud based document retention system and an electronic timekeeping system were part of additional technological improvements. Special projects included resurfacing trails, updating signage, maps, and entrances throughout the Park, repairing damage after two unusual flood events, increasing mowing from every 21 days to every 7-14 days, daily clearing and de-littering of ADA ramps and high-use parking lots, and daily restroom and sanitation services. The Conservancy also has arobust internship and research program for studying the diverse aspects of managing, improving and maintaining a forested urban park. In addition to this work, more than 3,000 volunteer hours were contributed toward the rehabilitation and beautification of the Park, all while working alongside professional staff and vocational horticulturists such as Master Naturalists and Master Gardeners. |
