A structure and Year 1 landscape inspections took place in April 2023. The inspection consisted of assessing all installed in-stream structures, bank erosion, health of the existing installed landscape plan, and non-native invasive vegetation. Year 1 post-construction monitoring activities will continue through the remainder of 2023, implement a non-native invasive eradication plan, and reseed bare spots throughout the project area. The next landscape inspection will take place later this year in Fall 2023.

A structure and landscape inspection took place on September 1, 2022. The inspection consisted of assessing installed in-stream structures, health of the newly installed landscape plan, and non-native invasive vegetation. Any unhealthy plants and trees are planned to be replaced as well as the removal of non-native invasive vegetation later this month. The three staging areas will be reseeded accordingly to promote increased vegetation growth. A follow-up inspection will take place in Spring 2023.

The walking trail at Diamond Farms Park continues to be open and accessible to the community. The fencing remains around the three staging areas until proper vegetative stabilization occurs. For your safety, please maintain a safe distance away from the staging areas when using the walking trail and navigating uneven terrain.

The walking trail at Diamond Farms Park is now open and accessible to the community. The fencing remains around the three staging areas until proper vegetative stabilization occurs. For your safety, maintain a safe distance away from the staging areas when using the walking trail and navigating uneven terrain.

The contractor completed all construction and landscape planting installation on May 18, 2022.

The contractor will continue to water and seed project area as needed throughout the upcoming warmer months. An inspection will occur during Fall 2022 growing season to assess both in-stream structures and vegetation health. The contractor will complete equipment and material demobilization in the coming weeks to include removal of traffic control signage in the area along Quince Orchard Blvd, Solitaire Ct., and the north end of Diamond Drive.

There is no change to the existing walking trail closures. The orange construction fence will remain until proper vegetative stabilization occurs within the project area. For your safety, please continue to use the permanent crosswalks to detour around sidewalk closures and maintain a safe distance away from the orange high-visibility fence.

The images below depict the plunge pool in Phase A and vegetation establishment of Phase B, both at completion.

The contractor completed all in-stream construction on March 11.

In the coming weeks, the contractor will complete any remaining upland grading and slope stabilization measures, decommission the haul road, reestablish the stream-side trail, dispose of unusable material, and begin planting the revised landscape plan.

Attached photos depict the installation of the last in-stream structure in Phase A and aerial photos of Phase B at completion.

Visible in some of the photos are the woody debris installed along the stream.  The role of wood plays an important part of fluvial aquatic and riparian ecosystems impacting stream/groundwater exchange, habitat utilization and stream biochemistry. Now that the construction work is completed, these debris features will aid in fully restoring the impacted area more quickly. More information regarding woody debris placement and its benefits can be found under the Documents section to the right called Benefits of Large Woody Debris in Streams.

There has been no change or update to the existing walking trail closures. Sidewalk closure and warning signs have been posted at Brown Station Elementary School, at the intersection of Solitaire Court & Quince Orchard Boulevard, and at Diamond Drive. For your safety, please continue to use the permanent crosswalks to detour around sidewalk closures and maintain a safe distance away from the orange high-visibility fence.

In the coming weeks, the contractor will begin in-stream construction upstream of Solitaire Court Culvert (Phase A).

In-stream construction is planned to be completed downstream of the Solitaire Court culvert (Phase B) in mid-February. In late December, the contractor ran into bedrock while excavating for in-stream structures and grading the floodplain.  Minor modifications to both a portion of in-stream log-step structures and the landscape plan were made. The plant species and count will remain unchanged, however, the plants’ locations will be change for increased survivability. The forest conservation requirements will continue to be met.

The contractor has been able to save two specimen trees that were proposed for removal. Some upland trees within the project area could also be saved. In addition, the contractor has been requested to place decaying trees and logs that can’t be reused in the project into park areas. A citizen made this request knowing the logs will provide increase ecological uplift.

Woody debris placement is an important part of stream ecosystems because it has a role in nutrient cycling, is a source of energy for aquatic ecosystems, provides habitat for terrestrial and aquatic organisms, and contributes to structure and roughness, thereby influencing water flows and sedimentation.

In-stream construction continues downstream of the Solitaire Court culvert (Phase B) and will continue in stages downstream. The bamboo grove area has been excavated and disposed of off-site. The area will be continuously monitored throughout the permit term for invasive vegetation and treated as necessary. In the coming weeks, tree felling will continue in segments, areas near the stream will be graded to create a new floodplain, and installation of in-stream structures will continue downstream. Material delivery complications and several storm events have caused the project schedule to slip, however, work on Saturdays in December will help to mitigate those delays.

The photos included with the status update depict log-step structures, part of a total system and stabilization of an open pipe that originates from an inlet on Solitaire Court. The stabilization and structures will help accomplish a number of project goals including dissipating flow velocity, minimizing sediment transport, and creating a more stabilized stream to help decrease erosion and provide ecological uplift and stream functionality.

In-stream construction at Diamond Farms Park for the Solitaire Court Stream Restoration project started on Tuesday, October 19. In-stream construction began at the Solitaire Court culvert (Phase B) and will continue in stages downstream. In the coming weeks, tree felling will continue in segments, the bamboo grove will be eradicated, areas near the stream will be graded to create a new floodplain, and installation of in-stream structures will begin.

Walking trail closure signs have been posted accordingly. See the trail closure map link posted under the Documents section of this page for more information. Sidewalk closure signs have been posted at permanent crosswalks both in front of Brown Station Elementary School and the intersection of Quince Orchard Blvd. & Diamond Drive. For your safety, please use the permanent crosswalks to detour around sidewalk closures and maintain a safe distance away from the orange high visibility fence.

Land disturbance at Diamond Farms Park for the Solitaire Court Stream Restoration project is expected to begin on or about Monday, September 27. Tree felling, which precedes the start of construction, is scheduled to begin on Friday, September 24. Start dates are weather dependent.

The construction contractor, KBS Earthworks, Inc., plans to begin land disturbance activity at Solitaire Court culvert (Phase B) and work downstream in segments to the confluence of Long Draught Branch. The upstream portion (Phase A), between the courts and tot lot downstream to Solitaire Court, is scheduled to begin after Phase B is complete. Walking trail closure signs will be posted appropriately prior to land disturbance. See trail closure map link posted under the Documents section on the right of this page. Sidewalk closure signs have been posted at permanent crosswalks both in front of Brown Station Elementary School and the intersection of Quince Orchard Blvd. & Diamond Drive.
