Home My WebLink AboutGolf Course ManagementPORT TOWNSEND GOLF COURSE MANAGEMENT SUMMARY History: Hastings Pond was part of Loren B. Hasting's original claim. The pond was enlarged in 1855 when Wm. Bishop and Wm. Eldridge, were hired to dig an adjacent well. At thirty feet the ground tumed moist and the bottom fell out, revealing a spring that overflowed into and became part of Hastings Pond. Drainage Basin: Basin 8, a closed basin, area up gradient of the wetland is approximately 280 acres. FEMA Zone- A Mapped Critical Areas: WDFW Priority Habitat/Species (Palustrine Aquatic, regular concentrations of waterfowl) Wetland Frequently Flooded Aquifer Recharge and Seismic GOLF COURSE LEASE 1996 included Exhibit C for buffer maintenance and enhancement/restoration. 2005 Lease is same MAINTENANCE Ponds and lakes serve many purposes on a golf course. In addition to dictating the fairway arrangement, the Port Toumsend Golf Course pond: Serves a drainage containment area Adds aesthetic value, and Provides priority habitats and species known to be identified and mapped by the Departrnent of Wildlife (PTMC I 9.05.080C2). The diflerent uses of a water body dictate the maintenance parameters to be considered. On going maintenance issues include: Invasive species control Stormwater ControVFlooding Vegetation management - maintain line of sight from the two T-off locations (on the west side of pond) to the green (on the east side) (Exhibit A, Aerial photo) Invasive Species Control (poison hemlock, scotch broom, Himalayan Blackberry) Poison hemlock: Along San Juan, especially at the south end in the blackbenies and on the berm Huge stand at the comer of the veterinary clinic -it may be the private landowner, but she says her fence line is the property line?

Either type of control, manual or chemical, is best done when it's young and in the low rosette stage, such as in March and April, before the flower stalks are up. At a minimum, cut every plant out and down and dispose of them before they go to seed. (J. Silver) Herbicides containing glyphosate are readily available and can be very effective, especially for larger infestations.

Stormwater Control/Flooding History: May I 1,2012? city proposed pumping excess water to lower pond level. Rick Mraz (DOE) wetlands specialist, ooas long as you do not drop the level below ordinary high, it is considered managing flood waters." Office of Regulator Assistance, Fran, says it depends on how much volume is being pumped. Possibly SEPA? Consider impacts to receiving area. Ken estimated at least 2-3 auefeet). September 20,2012, City crews "installed a rail fence where the stormwater pipe enters the golf course to prevent someone from stepping into this area because it is dug out a little deeper to allow the pipe to drain better and to identi$ where it is. I have attached a couple pictures of the area where we did the maintenance on the stormwater pipe that goes into the golf course for your information. We also put up a rail fence to prevent someone from driving in offof F Sfeet." Vegetation Management: History: Vegetation around the pond has been cut periodically since about 1995. In 20l0,the method was as follows: The vegetation, primarily cattails, would be cut using an arm offa riding lawn mower. Although the total area shown in the aerial photo is28,246 sf- in realrty, the mower arm will not reach beyond 20-feet in and thus only the outer edge of the vegetation would be cut (to a height of about 3-4 feet). WDFW (Gloria Rogers, Area Habitat Biologist) requested information on type of wetland habitat, square footage and type of vegetation to be cut, method, size of trees, how short will it be cut and how often. In addition "a horizontal measurement so we can determine the undisturbed distance to the water". City replied that the mower arm will not reach beyond 2}-feetin and thus only the outer edge ofthe vegetation would be cut (to a height of about 3-4 feet). WDFW replied "so how much distance will be left between the cut edge and the water? How about the minimum and maximtm. " Staff provided a site plan that shows the wetland edge - a 20-foot "mow area" and then the min. and max. Remaining buffer.

For those basins within Port Townsend having no natural outlet, the director may choose to increase design standards as needed to protect citizens and the environment from damages that may result due to the increased likelihood of flooding. F. Mitigation or Compensation. 1.

The basic project purpose cannot reasonably be accomplished on another site or sites in the general region while still successfully avoiding or resulting in less adverse impact on a wetland; and ii. All on-site alternative designs that would avoid or result in less adverse impact on a wetland or its buffer, such as a reduction in the size, scope, configuration or density of the project, are not feasible. 16.08 Flood Damage Prevention 1 6.08.1 20 Development permit required. A development permit shall be obtained before construction or development begins within any area of special flood hazard established in PTMC 16.08.070. The permit shall be for all structures including manufactured homes, as set forth in PTMC 16.08.050, and for all development including fill and other activities, also as set forth in PTMC 16.08.050. (Ord. 2161 S 4.1-1, 1999). D. Description of the extent to which a watercourse will be altered or relocated as a result of proposed development. D. Alteration of Watercourses. 1. Notify adjacent communities and the Washington State Department of Ecology prior to any alteration or relocation of a watercourse, and submit evidence of such notification to the Federal lnsurance Administration. 2. Require that maintenance is provided within the altered or relocated portion of said watercourse so that the flood-carrying capacity is not diminished. NT'IP/ESA Biological Opinion Reporting Tool In order to demonstrate how we will meet the minimum criteria for the NFIP and the Endangered Species Act, the City opted for Door 3: show compliance with ESA on a permit by permit basis. Thus, we submit the reporting tool annually. Required fields include habitat assessment/habitat mitigation/ Floodplain filled to the nearest 1/lOth of an acre We will, but have yet to amend Chapter 16.08 to require a Habitat assessment for development in the Special Flood HazardArea (A&V Zones) with an exemption for Golf Course Pond, Chinese Gardens & Kah Tai, as they are non salmon bearing. Are there any ESA listed species currently present? Were any of the ESA listed species historically present in within the ESA Potential Impact Area? (Daniel Dafoe 7l20ll4) "To my knowledge, there are no ESA-Iisted species currently present. I do not know whether any ESA-Iisted species were historically present." However, the Bioop was targeting salmon and orca -thus should be exempt. C :\Users\j udys\AppData\Local\l\4icrosoft \Windows\Temporary Intemet Files\Content.
