    Mitigated Determination of Non-significance (MDNS)

    File No. PLN18-0013

    Project Name:  Ten Trails Master Planned Development (MPD) – Phase 2 Plat A Preliminary Plat

    Project Description:  The applicant is proposing to subdivide 66.5 acres within the Ten Trails MPD into 211 single-family residential lots. Approximately 28.6 acres are designated as tracts for open space, park, sensitive area, and utility uses. There are ten identified wetlands within the boundary of this preliminary plat application. A wetland buffer averaging plan has been submitted in association with the preliminary plat application (application number PLN18-0015), which proposes a net increase in buffer area and no direct impacts to wetlands.

    Project Proponent:  Oakpointe / CCD Black Diamond Partners LLC

    Location:  Approximately ½ mile southwest of the intersection of Lake Sawyer Road SE and Roberts Drive, and immediately south of The Villages Phase 1A Plat. Located on King County parcel numbers 152106-9106, 152106-9109, and 22106-9053.

    Title of Document Being Adopted:  The Villages Master Planned Development Final Environmental

    Impact Statement (FEIS).

    Agency that prepared the document:  City of Black Diamond

    Date adopted document was prepared:  December 11, 2009

    Description of document being adopted:  FEIS for a 1, 196-acre master planned mixed use development 

    Including 4800 dwelling units; 775,000 sq. ft. of retail, office, light industrial, educational, recreational, 

    and open space uses. 

    If document being adopted has been challenged (WAC 197-11-630), please describe:  Extensive

    Mitigated Determination of Nonsignificance:

    After review of the FEIS adopted above, the completed environmental checklist, the Ten Trails Master Planned Development (MPD) – Phase 2 Plat A Preliminary Plat and supporting materials (application number PLN18-00008), and the Wetland Buffer Averaging Plan (application number PLN18-0015), the lead agency has determined this proposal will not have a probable significant adverse impact on the environment if the mitigation measures set forth below are implemented.  Therefore, neither a new environmental impact statement (EIS) or supplemental environmental impact statement (SEIS) is required under RCW 43.21C.030(2)(c) or WAC 197-11-600.

    In accordance with WAC 197-11-158, mitigation measures include those required by applicable provision of the Black Diamond Municipal Code, the Comprehensive Plan, City of Black Diamond Engineering Design & Construction standards, conditions of the Villages Master Planned Development (MPD) permit approval in Ordinance No. 10-946, the Villages MPD Development Agreement (DA) approved in Ordinance NO. 11-970, and as imposed by this MDNS.

    6. Reduce short term construction noise by employing best management practices such as minimizing construction noise with properly sized and maintained mufflers, engine intake silencers, engine enclosures and turning off equipment when not in use. 

    7. Locate stationary construction equipment away from sensitive receiving properties or use noise barriers to direct noise away from sensitive receiving properties. 

    8. Require operators to lift, rather than drag materials. 

    9. Wherever feasible, use electric models for impact tools such as jackhammers, rock drills and pavement breakers and specify electric pumps whenever pumps are required.
