Background and History:

The City of Flagstaff’s Water Services Division has been operating the Lake Mary Water Treatment Plant (LMWTP) under a Special Use Permit from the Forest Service since 1941.   As the cities second major potable water supply, the LMWTP treats up to 8 million gallons of water per day (8 MGD) from Upper Lake Mary (ULM) and has been a critical water supply for the citizens of Flagstaff for nearly 81 years.  Additionally, the plant also serves as a treatment location and distribution point for the City’s groundwater supply from the Lake Mary Wellfield.  Today the LMWTP provides over half of the water supply for nearly 80,000 residents and is a critical component of our City’s water supply infrastructure. 
 
Flagstaff is located within the high desert ponderosa pine forest of northern Arizona where water supplies are often a challenge to locate and are critical to the economic growth and development of our mountain community.  The Forest Service, National Park Service and the City entered into a Stipulation in December 2001 (Civil No. 6417), that among other things, confirmed the City’s water rights of 15,653 acre-feet/year to be stored in ULM and treated at the LMWTP. 
 
The existing LMWTP is made of several buildings that house the operations control room and laboratory, storage for chemicals and anthracite/sand filters used in the treatment process, chlorine gas for disinfection, a clear well and booster pumps to deliver water to the community.  Additionally, the treatment plant has multiple sedimentation and flocculation basins for treatment, drying beds for sediment disposal and two (2) water storage tanks.  Given the age of the plant, the City has identified numerous major capital improvements that are necessary to upgrade over the coming years.  These types of significant upgrades often require pre-approval from the Forest Service which can create long, unnecessary delays.  In the past, this situation has led to significant impacts to the City’s ability to upgrade critical treatment plant infrastructure in a timely basis putting at risk a major water supply for our community.
 
Additionally, the City would like to acquire land adjacent to the existing treatment plant for possible planned expansions.  Specifically, 27 acres to the north, northwest, west and south of the treatment plant have been included with the Agreement of Intent for a Direct Sale.  The health of the ULM watershed has been compromised with small diameter, densely spaced ponderosa pine trees and there is a significant risk of a catastrophic crown fire within the watershed that would directly impact the quality of water to be treated at the LMWTP.  A mitigation technique the water production section could apply to damaged water quality from a catastrophic wildland fire would be the addition and use of pre-sedimentation basins, requiring additional acreage.  These pre-sed basins would be used to assist surface water production should ULM experience a water quality degrading forest fire surrounding ULM.  Additionally, Flagstaff Water Services has considered the possibility of direct or indirect potable reuse with the addition of infrastructure, requiring additional acreage, at the LMWTP that could enable these possible future water supplies.  To make these type of plant expansions happen in expedited fashions, the City would like to purchase the extra land adjacent to the water treatment plant as identified in the attached survey. 

In summary, the purchase of 49 acres the Lake Mary Water Treatment Plant currently resides on and is adjacent to from the Forest Service will allow Flagstaff Water Services to continue the timely repair, maintenance and possible addition or upgrades of current and future infrastructure necessary for the potable water supply to the City of Flagstaff.  Flagstaff Water Services has been working with the Forest Service on this property purchase for over a decade.  This Agreement of Intent with the Forest Service is one of many steps towards a final land purchase agreement.
