Home My WebLink AboutAs Built Monitoring Plan - PLN General - 1/25/2001 �r I C January 25, 2001 Mr. Allan Borden Mason County Planning Department P.O. Box 186 Shelton, WA 98584 RE: AS-BUILT AND MONITORING PLANS FOR THE GRAPEVIEW RV PARK PROJECT Dear Mr. Borden: The following are the As-Built and Monitoring Plans as outlined under Sections 2.7 and 4.0 of the Wetland Mitigation Report (BA#3016) dated 13 July 2000 for the referenced property. The Monitoring Plan follows the outline as defined in Section 2.7 in the above report beginning with Section 2.7.1 . The goals and objectives of the Mitigation Plan (BA#3016) have been reviewed and verified that all work has been completed in accordance with the B & A Report. 2.7.1 Vegetation The vegetation of the mitigation area was monitored with the placement of five monitoring plots as shown on accompanying Figure 6. Sample plots measuring 20 x 20 feet were established and flagged in the field on 20 January 2001 . Monitoring forms for each of the sample plots provide strata, number of plants, condition, percent cover, and percent survival. Desirable volunteers and invasive exotics are also included (Attachment 1 ). The landscaper's planting list is enclosed as a separate page at the end of this report. 3303 43rd St. NW, P.O.Box 1337, Gig Harbor WA 98335 USA 253.858.7055 Fax 253.858,2534 ba@harbornet.com 2.7.2 Water Regime The water regime of the wetland mitigation area meets wetland hydrology conditions throughout the mitigation area. The monitoring plots verify the presence of wetland hydrology in each of the wetland sample plots. Per B & A letter of 18 September 2000, the Mitigation Plan was substantially altered from the original concept by the presence of a water table in the mitigation area that was not anticipated. As a result of intercepting groundwater, we are generally creating a freshwater marsh in much of the wetland rather than a Palustrine Forested wetland. The eastern portion of the wetland is mostly open water that will naturally fill in with emergent plants and surrounding Wetlands E and F. The western portion of the wetland has been replanted to a Scrub/Shrub and Forested plant community. The soil test holes found wetland hydrology within 6 inches of the surface throughout the created wetland area, while the open water area in the eastern portion of the wetland was ponded. 2.7.3 Soils Soil monitoring found the soils in the mitigation area forming hydric soil characteristics. In the lower profile at approximately 12 inches, the soils were beginning to form lower chromas indicating anaerobic conditions and the reduction of iron. These soil formation processes are typical of hydric soils. 2.7.4 Fauna The Monitoring Form addresses wildlife. At this early time, no wildlife was observed in the wetland; however, a pileated woodpecker was observed roosting in a nearby tree. 2.7.5 Development of Habitat Structure It is too early to provide for habitat structure, as this is an As-Built Report and the plants are newly installed; however, the items per the Final Mitigation Report are addressed as follows: • Tree structure in and around the wetlands will develop from existing and planted trees. 3016L6/ajb/smh/1/25/01 2 • Several snags, stumps, downed trees, and woody debris have been placed in the wetland area per accompanying photographs. • Canopy cover will likely form from the plantings. • Structural levels will likely include Forested, Scrub/Shrub, Emergent, and Open Water over time. • The mitigation area is connected to Wetlands E and F on three sides, which is all left as open land. The area on the north and south of the wetland has been logged and is currently regrowing into a Forested community, while it is presently a Scrub/Shrub Emergent plant community. To the west is a Forested plant community. • The adjacent land use from the wetland to the west is undisturbed forested, while to the north and south will be undeveloped wetland areas. To the east will be buffer with eventual development of single family residences. • The presence of priority habitats is not applicable, as there are none on or near the site. 2.7.6 Water Quality Water quality is not monitored. 2.7.7 Buffers Buffer Photo Station Looking NE (Plot 5) documents the buffer vegetation and shows the buffer area. 2.8 Site Protection Upon development of the area around the wetland, protective buffers were established as shown in Attachment 2. 3.9 Maintenance and Contingency plan Whereas this is an As-Built Plan, there is no call for maintenance or contingency measures at this time. 3016L6/ajb/smh/1/25/01 3 This concludes the As-Built Mitigation Report for the recently constructed mitigation area in accordance with B & A report (BA#3016) of 13 July 2000. The next Monitoring Report will be submitted in July 2001 . If you have any questions or need additional information, please feel free to contact me at 253-858-7055. Sincerely, A. J.
