Jefferson County Comprehensive Plan: Port Hadlock/Irondale UGA

URBAN GROWTH AREA ELEMENT

From Jefferson County Comprehensive Plan, Chapter 2, about the Urban Growth Element. These excerpts have important points to consider related to the Hadlock UGA highlighted in bold text.

“There is no sanitary sewer system presently in the UGA. All wastewater treatment is provided either by individual on-site septic systems or small community-based on-site systems. The Jefferson County Environmental Health Department records indicate no significant failure rates for existing on-site systems in the UGA.”

Page 10:

In the case of Irondale & Port Hadlock, the lack of a community sewer system is a significant impediment to economic activity since it limits overall employment density and certain economic activities that may be water-use intensive or require special waste processing needs.

The Irondale & Port Hadlock (UGA) water system serves the entire UGA and is part of a network of interconnected public water supply systems that serve the Quimper Peninsula operated by the PUD. The UGA system currently has 1,850 connections and projects a total of 3,171 connections by 2025. The water system was purchased by the PUD from the City of Port Townsend in 2002. The system contains two major wells: the Sparling Well and the Kivley Well. The Sparling well and treatment plant currently serve as the primary water supply source for the UGA, the Sparling well was originally drilled to augment the surface water supply to the Irondale and Port Hadlock area from the City of Port Townsend water supply line. The Kivley well was brought on line in 1972 to provide an additional supply.”

“The existing water supply source meets the current demands on the UGA water system, however the wells need to be brought up to their full water right. PUD studies indicate that if the state DOH water system design standard of 466 gpd/ERU is used, the UGA water system may only have enough water until the year 2015. The PUD indicates, however, that based on an average daily demand of 350 gpd/ERU (actual PUD consumption records), the PUD water system supply has adequate water rights sources for the 20 year planning period. The PUD water system plans indicate that a water conservation plan, lower actual UGA water usage (based on local consumption records) and planned system improvements will result in enough water supply to meet the 20 year planning horizon. However, in the best interest of a regional approach to water resource management, the PUD is also in discussion with the City of Port Townsend about purchasing and treating additional wholesale water for the PUD water system. This may provide for a more equitable and better long-term solution to meeting projected demands on the resource.

“There are two outfalls to Port Townsend Bay in the UGA. They convey runoff collected by the Port Hadlock Core storm sewer system and road drainage from Moore Street in Irondale.”

“Due to the relatively low level of development in the UGA, there is not a high volume of stormwater currently being discharged into Port Townsend Bay. Thus, the overall impact on water quality in the Bay associated with storm sewer outfalls appears to be limited. High fecal coliform counts have been reported in Port Townsend Bay during the summer. However, the UGA Stormwater Management Plan indicates that based on the levels, timing, and location, they do not appear to be associated with runoff from the Port Hadlock storm sewer system or Moore Street.”

“Nonetheless, the pollutant concentrations are sufficiently high that runoff treatment should be provided, according to the recommendations made in the UGA Stormwater Management Plan. In order to accomplish this goal, the County should coordinate with the Washington Departments of Transportation and Fish and Wildlife and with private landowners to plan, design, fund, and construct treatment facilities at both locations. Hydrologic modeling was used in the UGA Stormwater Management Plan to develop planning level cost estimates for replacing the outfalls and adding a treatment swale for both the Port Hadlock Core storm sewer system and the Moore Street drainage system.”

“The UGA Stormwater Management Plan proposes two capital projects: a stormwater treatment facility and replacement of an existing outfall. The treatment facility will cost approximately $10,000; the cost to replace the outfall would be approximately $144,000. (2004 Year Dollars)”

“The UGA Stormwater Management Plan proposes that parcels in the UGA Commercial, Industrial, and Multi-Family Residential designations would pay a stormwater management fee to fund inspection of stormwater management facilities in those areas. The inspection program would cost approximately $10,000 per year.”

“The UGA Stormwater Management Plan proposes a UGA Stormwater Management Program that would conduct public education, water quality monitoring, and stream gauging. The annual SWM Program cost would be approximately $15,000.”

“The Washington State Growth Management Act (GMA) was passed in 1990 to encourage planned, coordinated, growth for a more efficient use of the State’s resources by reducing sprawl. One of the ways in which the GMA seeks to accomplish these goals is to require communities to adopt comprehensive growth plans that specify how new population growth will be accommodated. By law, these plans must address the following areas: transportation, capital facilities, utilities, land use, housing, and rural land.”

“This assumes that the availability of a sanitary sewer system will affect the rates of development. After the UGA designation is completed and prior to the development of a sewer system, urban commercial and industrial development will be permitted, but only by those developments that can be served by an on -site septic system. It is assumed that the sanitary sewer system will be available by 2011 to designated areas. Using these development rates, 12.6 acres of commercial and industrial land are estimated to be developed during the 2005 -2010 planning period and 54.3 acres developed from 2011 to 2024. This growth scenario includes a 15% market reduction factor to account for land that will be unavailable for development during this period.”

“Growth and development in the Irondale-Port Hadlock UGA will have some impacts to the transportation system. A significant portion of that impact will occur on SR19 and SR116. The Washington State Department of Transportation (WSDOT) has jurisdiction over these roads. Continued and increased intergovernmental coordination between WSDOT and Jefferson County will become more important to coordinate transportation improvements within and adjacent to the Irondale -Port Hadlock UGA. The coordination will be necessary to accommodate future population growth and development while mitigating the resulting impacts and increased congestion from both within and outside the UGA.”

From United States Environmental Protection Agency:

Aquifer depletion. Stressors that can deplete aquifers include changes in precipitation and snowmelt patterns; withdrawal of ground water for drinking, irrigation, and other human uses; and impervious paved surfaces that prevent precipitation from recharging ground water. Some deep aquifers may take thousands of years to replenish. Some consequences of aquifer depletion include:

  • Lower lake levels or—in extreme cases—intermittent or totally dry perennial streams. These effects can harm aquatic and riparian plants and animals that depend on regular surface flows.
  • Land subsidence and sinkhole formation in areas of heavy withdrawal. These changes can damage buildings, roads, and other structures and can permanently reduce aquifer recharge capacity by compacting the aquifer medium (soil or rock).
  • Salt water intrusion. Changes in ground water flow can lead to saline ground water migrating into aquifers previously occupied by fresh ground water.
