Townscape is currently contracted by the Honolulu Board of Water Supply (BWS) to develop the Primary Urban Center Watershed Management Plan (PUC WMP), a long-range plan that inventories and assesses the water resources and future water demands of the Primary Urban Center District of Oʻahu.
The PUC District includes all of urban Honolulu, stretching from Kahala/Kaimukī in the east and Pearl City in the west, and covers an area of about 105 square miles (or about 1/6 of the island of Oʻahu). The population of the PUC in 2010 was 420,000 people.
The PUC WMP is one of the eight district watershed management plans that the BWS is developing, which together will constitute the Oʻahu Water Management Plan. The plan includes projections for water use and water supplies for the year 2040, as well as very long-range estimates of water demand and water supplies for the year 2100.
It also includes an analysis of critical watershed issues and concerns, as voiced by public agencies, non-profit organizations, and residents, and describes watershed management projects and strategies that can be implemented to address these issues. In 2019 the PUC WMP will be presented to the BWS Board of Directors, to the Honolulu City Council, and to the State Commission on Water Resource Management for adoption and approval.
