Bid Item 2 Construct Bypass Structures, Divert Creek, Rescue Fish, and Drain ' Sediment Basin (LS) This items includes all work needed for construction of temporary bypass structures, diversion of Maplewood Creek from the work areas, draining the sediment basin, and coordination with adjacent private property owner regarding water supply into a private fish pond. See the description and photos of 1999 cleaning for an example of the work and techniques needed. During all work approximately 3/4 of the flow shall be kept moving downstream so the creek is not dewatered and fish life is not lost. Upstream Bypass Structure and Creek Diversion The upstream bypass structure will be constructed upstream of the sediment basin, next to the 18-inch bypass inlet. The bypass structure will divert the entire flow from the creek into the 18-inch bypass pipe to prevent water from flowing to the sediment basin. The bypass structure will be at least as high as the top of the bypass pipe, plus 3 inches. One type of material that may be used for the bypass structure is sandbags (or media bags) and plastic sheeting, keyed into the creek bed to limit potential underflow. Dirt fill shall not be used to construct the bypass structure. Water shall be kept flowing to the fish channel on the golf ' course at all times. It will be necessary to dig a sump downstream of the bypass structure and install a sump ' pump to collect any water running under the bypass structure and redirect it back into the bypass pipe. Pumping will be required 24-hours a day to keep water from flowing to the sediment basin The work shall be planned and executed so the temporary bypass structure will be completed early in the morning (approx. 8 to 10 am), and the remainder of the day will be used for draining the sediment basin and fish rescue. IDrain Sediment Basin ' After the upstream bypass structure is constructed and the creek is diverted, the sediment basin may be drained using the 8-inch valves in the concrete structures. Before draining starts the Contractor will place plastic sheeting anchored by sandbags on the bottom of the basin, 5 to 6 feet out from the valves, to help reduce the amount of bottom sediment that may be stirred up and discharged through the valves. After the water is drained as low as the valves will allow, the Contractor will use a portable 1 pump to completely dewater the sediment basin. The 8-inch underdrain may also be opened to allow the sediment to dewater. If the water from the underdrain is too silty to discharge to the creek other means may be used to dewater the sediment. The contractor shall not discharge sediment laden water to the creek.

Fish Rescue All fish and other aquatic life shall be rescued from the creek, sediment basin, and fish ladder and transferred to the downstream creek per the HPA and Fisheries regulations. ' At a minimum the Contractor shall have the following at the site for fish rescue from the sediment basin: • three laborers dedicated for fish rescue, • four nets (approx. 6"x 8") with handles, • four buckets for capturing fish, • a portable gas pump with an intake strainer meeting Fisheries requirements ( see HPA#13 1/8" intake screen sized for a surface velocity of 0.4 fps ). The contractor shall have the equipment on site for City inspection the day before installing the bypass and draining the basin. If the equipment is not satisfactory, and workers are not onsite the day of the bypass, installing the bypass and draining the basin shall not proceed. Fish rescue shall start with the workers walking the creek bed and rescuing all aquatic life immediately after the bypass structure is completed and flow is directed into the 18-inch pipe. Fish rescue shall continue while the sediment basin is being drained. Workers shall repeatedly walk the creek bed and sediment basin and continue to capture any fish present until the basin is drained. It may be necessary to use hip waders to reach fish in the middle of the basin. It will be difficult to wade through the silt sediment at the south end of the basin. Each bucket shall be emptied within 1 hour after the first fish is placed in it. ' Captured fish shall be released to the creek downstream of the flow splitter structure. Coordination with Private Property Owner , The private property owner (Mr. Casey McCarthy) adjacent to Maplewood Creek operates a fishpond on his property. The Contractor will be responsible for coordinating with Mr. McCarthy to keep sediment laden water from entering his fish pond while the basin is being cleaned. The City will assist the Contractor with coordination by notifying Mr. McCarty of the work no less than 1-week prior to the anticipated start date. During the maintenance period, the Contractor will be responsible for closing the valve 1 (located on the east side of the overflow spillway) that supplies water to the fish pond. The valve must be closed before dewatering begins to avoid discharge of any silt laden water ' into the fish pond. After the inlet valve is close, Mr. McCarty will be responsible for supplying water to his fish pond from the creek next to his property. He usually placed a small pump in the creek adjacent to his property. The Contractor will be responsible for not disturbing Mr. McCartys pump and notifying McCarty at least 24 hours before gravel is placed in the creek above or adjacent to his property. Flow Splifter Structure and Creek Diversion Work on the flow splitter and sediment removal between bridges shall not occur on the days identified in Bid Item #1.

The bypass structure may be constructed of sandbags and plastic sheeting, or using a different method chosen by the contractor. Regardless of the procedure chosen by the contractor, the diversion must allow the removal of accumulated sediment from the flow splitter basin without impacting the turbidity in the low flow channel. Water shall be kept 1 flowing to the fish channel on the golf course at all times. When the bypass is constructed the Contractor shall be responsible for immediately rescuing any fish stranded in the bypass section before removing accumulated gravel and sediment. Sediment Removal Between Bridcles (Note 11J5) The Contractor shall install a temporary bypass structure to contain or isolate the area for sediment removal, and prevent sediment from washing downstream during cleaning. Sandbags, plastic sheeting, and filter fabric can be used to build a bypass or isolation structure, similar to the one used for the Flow Splitter structure. Water shall be kept flowing to the fish channel on the golf course at all times. Payment for this item will be made at the lump sum amount bid, and considered complete compensation for all design, labor equipment and materials required to complete this item of work in accordance with the Contract Documents. Payment will be prorated as the work is accomplished. Bid Item 3 Remove, Haul, and Dispose of Sediment (LS) This item includes removing the accumulated sediment from all locations (the sediment basin, the channel at the north end of the basin, the area between the bridges, and flow splitter), loading the material into vehicles, and hauling to a private site for disposal. All costs for excavation, loading, hauling, and disposal shall be included in the bid price. • Sediment in the sediment basin and upper channel shall be excavated using a smooth bucket to avoid disturbing and damaging the imported backfill layer and PVC liner. • Only singe dump trucks may be used across the bridge to the sediment basin, no truck and trailer combinations. Sediment Basin The accumulated sediment above the imported backfill layer shall be removed and disposed of offsite. The sediment basin, and channel at the north end of the basin, have a 12-inch layer of imported backfill placed above a 30 mil PVC liner. The imported backfill layer is different from the sediment and it is possible to differentiate between the two materials by sight and feel. The contractor shall use the sediment basin construction plans and as-built plans to locate the top of the 12-inch imported backfill layer. The Contractor shall hand dig test holes to confirm the location and elevation of the backfill layer, and PVC liner at the start of construction, and during excavation, when needed. Test holes are more likely needed at the edges of the basin where the PVC liner is close to the H:\File Sys\SWP-Surface Water Projects\SWP-27-Surface Water Projects(CIP)\27-2057 Maplewood Sed Basin\2008 Pond Cleaning\1110 FINAL SPEC-2006 Spec\20d-Bid Section I-09-14.doc Page 5of 11 surface, than at the center of the basin. The locations and elevations of test holes shall be t reviewed with the City prior to starting excavation, and wherever they are performed during the excavation. Upper Channel The accumulated sediment in the upper channel north of the sediment basin will be removed ' to restore the area so it is similar to the as-built plans and the post construction photos. The center section of the channel is approximately 8 to 12 feet wide, and has rock berms at several locations along across the bottom and along the side. In the middle of the channel sediment shall be removed to the top of the rock berms. Along the sides sediment must be carefully removed from between the rock berms without disturbing them. Some rocks may need to be adjusted or added to the berms. City personnel will be available to help identify the extent of sediment removal, adjustments to sediment removal, and any adjustment needed to the rock berms. The PVC liner is close to the top of backfill in this area so hand dug test holes will be needed to identify the liner ' location. PVC Liner The contractor is responsible for protecting the PVC liner under the sediment basin and north channel during excavation, and is responsible for repairing any punctures or tears that may be caused by operational mistakes. Operational mistakes include not hand digging to identify the liner location, digging too deep, digging beyond the liner limits shown on the construction and as-built plans, and not properly protecting the liner from potential damage from vehicle traffic. Any major punctures or tears shall be repaired by seaming a new PVC patch over the affected area in accordance with manufacturers recommendation and industry practice. Seaming shall be done by a company with experience in PVC liner construction and seaming. Minor tears may be repaired by other means (tape or gluing), if approved by the City. Flow Splitter and Area Between Bridges Work on the flow splitter and sediment removal between bridges shall not occur on the Golf Course Event Days identified in Bid Item #1. The accumulated sediment in the flow splitter basin shall be removed to match the original elevation of the bottom of the high flow weir. The bottom of the weir is located approximately 2.5 feet below the weir crest. The excavation shall slope gently upstream to blend into the channel at the north end of the flow splitter. Accumulated sediment on the south side of the splitter structure shall be removed down to the rip-rap layer. The locations and elevations shall be reviewed with the City prior to starting excavation. The excavated sediment shall be removed and disposed of offsite. Accumulated sediment and vegetation in the area between the bridges shall be removed to the bottom of the channel and the rockery on the east bank. The excavation extent shall be reviewed with the City prior to starting excavation, and may be adjusted as the work proceeds. The excavated sediment and debris shall be removed and disposed of offsite.

Then in December 2007 we had storms with a peak rainfall of 4.2 inches in 24-hours, which exceeded the 100-year, 24-hour storm (3.9 inches). The storms caused a large amount of erosion and sediment, and completely filled the Maplewood Sediment Basin and Flow Splitter. Attached are pictures of the basin and flow splitter before and after the storm. We will need to do the entire cleaning project again in 2008. I The Army Corps of Engineers June 29, 2007 letter authorizing the work stated that the NWP authorization was valid for 2 years after the date of the letter. Our cleaning project in 2008 will be exactly the same as in 2007. We will use the same techniques to temporarily divert the water around the sediment basin and flow splitter, and will clean the same areas as before. The work will be scheduled for August 2008, within the time period allowed by the NWPs and Washington Dept. of Fish and Wildlife HPA.

The following notes and attached figures and photos are for future reference when the basin needs cleaning again. Time Needed 9/20 Monday Mobilized to site - 4 to 6 hrs 9/21 Tuesday Setup, organize, try to build first bypass dam (not successful) - 8 hr 9/22 Wednesday Build bypass dam - 2 to 4 hr (with material from previous day). Drain basin and Rescue fish - 4 to 5 hrs. 1 9/23 Thursday Start removing sediment, stockpile to dewater- 8 hrs 9/24 Friday Removing sediment, haul to dispose on golf course - 8 hrs 9/25 Saturday Removing sediment, haul to dispose on golf course - 8 hrs 9/27 Monday Finish removing sediment, place rocks in upper creek, start refilling basin over night - 8 hrs 9/28 Tuesday Place rocks in upper creek, remove bypass dam, drain and close bypass pipe, general raking. - 8 hrs 9/29 Wednesday General clean up and demobilize - 8 hrs (est.) i Cleaning takes about 2 weeks. Allow more time for the silty sediment to dry out. r Cost Because we the proposed lump sum prices from the fish channel contractor (we already had a contract with) seemed too high we decided to use T & M for the work. It cost about $3,200 per day (full working day, excavator, loader, dump truck, including 8.6% tax). Disposal cost was minimal because the golf course took all the material for landscaping and future course revisions. The cost for hauling off site was estimated at $10 per cy for the truck and driver, plus $4 per cy for dry soil or $8 per cy for wet soil. The material could have gone to a soil site near Cedar Hills landfill, about a 2 % hour round trip. 1 Observations and Lessons Learned McCarty Trout Pond Be sure the adjacent property owner with the fish pond (Casey McCarty) is notified at least one week before the work starts. He will have to get a pump and place it in the creek adjacent his property to keep his fish pond full of fresh water. Be sure his inlet valve (in the sediment basin) is closed before starting to dewater the basin. Open the old bypass valve on the golf course (at the southeast corner of the pump shack, the key for the valve is in the pump shack). When that valve is closed it allows McCarty to back up water in the pipe into his pond. When the valve is open it allows water from the pipe (and sediment basin) to drain into the old creek bed. Bypass Dam ' Build the bypass right at the concrete inlet. First place sand bags across bottom of creek to conform to bottom and help form a seal. Then place media bags (fabric bags filled with gravel/sand, about 3 ft square) on top of the sand bags. Place plastic membrane (one large sheet) on top of media bags and extending upstream about 15 feet out from bags. The membrane is placed about 15 feet upstream of the dam to help seal the bottom and reduce water bypass under the dam. The plastic membrane should be directed into the bypass structure. Use sand bags on top of the membrane and on the sides to seal it. Need sand bags along the upstream edge to help seal it. Dig a sump downstream of the bypass dam (about 5 to 8 feet) and place a submersible pump in it. Pump any seepage that gets past the dam back upstream. Be ready to rescue fish in the creek immediately after the bypass dam is placed. HAFile Sys\SWP - Surface Water Projects\SWP-27 - Surface Water Projects (CIP)\27-2057 Maplewood Sed Basin\02-1999 Pond Cleaning\Memo-Cleaning Notes.DOC\DWC\tb fDewatering Basin Start early in the day ! Use the 8-inch valve in the overflow weir and fish weir to initially draw the basin down. Slowly let the flow out to minimize the sediment stirred up. When the old valve at the golf course shack is opened the McCarty inlet can also be used to draw down the water level. After the water level is below the valve invert use a portable pump to remove water from the bottom of the basin. Flow from the 8-inch underdrain pipe is slow and didn't seem sufficient to dewater the sediment. ' Fish Rescue Allow the entire day to draw the pond down and rescue fish. The fish need to be rescued as soon as possible. When the water level is low it may get too hot or oxygen depleted to allow them to survive for more than a few hours. Draw the water level down so there is only a small pond area, then net the fish in the pond (on 9/22/99 we captured about 40 to 60 fish from the pond). The WDFW electro shocker didn't seem to work too well. We turned it up to higher level than shown on the instructions. Some fish were shocked and beached themselves, making capture easy. Wading with the shocker stirred up the silt and made it hard too see any shocked fish. When the water level was low (4 to 8 inches) it was possible to lay on the overflow weir and reach down to net fish. This worked a little better than electro shocking. When the McCarty inlet is used to drain the pond one person should be at it to net fish. A large number of smaller fish (1 to 2 inch) were captured there. Some of the rescued fish were placed in the top cell of the fish ladder, some were placed in the bottom cell or pool at the outlet. Recommendation - Make a large net (say 1.5' high by 3' to 4 ' wide) so it's easier to scoop and capture fish. The net will have to be made before the project begins. You could also try to use an area net cast on the bottom, herd the fish to that side, then draw it up and capture them. Silty Soil at South End of Basin Clean the basin before more than 1 foot of silt accumulates at the south end. jThe silty soil at the south end needs time to dewater. Allow 3 to 4 days in the hot sun after the basin is emptied. It may also help to stack the silty material in the basin and let it continue to dewater before finally hauling away for disposal. l H:\File Sys\SWP - Surface Water Projects\SWP-27 - Surface Water Projects (CIP)\27-2057 Maplewood Sed Basin\02-1999 Pond Cleaning\Memo-Cleaning Notes.DOC\DWC\tb Sediment Removal First the trackhoe worked at the north end of the basin on the stable granular sediment. It scraped the upper channel, then moved onto the delta at the north end of the basin. It was able to sit on the delta, scrape the granular soil toward it, and form a large stockpile that would dewater. A front end loader was used to move granular soil stockpiled at the north end to a stockpile in the upper parking lot. The 1 foot granular layer above the liner felt hard when encountered, and was stable for the trackhoe to drive on. It was easy for the operator to detect when he had excavated through the sediment and reached the granular layer. The operator stockpiled some silty material on the granular soil and let it dewater over night. It lost some water and seemed drier and easier to work the next day. Recommend - Allow the silty soil 2 days to dry in place, then pile it in stockpiles in the basin so it can dewater further. Refilling the Basin It took about 12 to 16 hours to completely refill the basin at about 1/2 the flow. The 8-inch valve in the fish weir was opened about %4 of the way and the water level in the fish weir and basin was allowed to stabilize overnight. That placed the water level in the pond at about 4 inches below the fish weir. Next the bypass dam was removed and all the creek flow went into the sediment basin. The 8-inch valve in the overflow spillway was opened to keep about '/2 the total flow to the fish channel on the golf course (it should NOT be dried up). The water level in the pond was allowed to rise to just below the fish weir. The water level in the upper cell in the fish ladder needed to be draw down to drain the 18- inch bypass pipe, and avoid trapping any fish that may have swum into it. The 18-inch valve on the southwest side of the fish ladder was opened to draw down the water in the upper cell, the bypass pipe valve was closed, then the 18-inch fish ladder valve was closed. The 8-inch valve in the fish weir was opened to refill the upper cell from the sediment basin. tThe upper cell took about 1 hour to fill. The water level in the pond took about another hour to reach the top of the fish weir and begin flowing into the fish ladder. After flow had reestablished itself in the entire fish ladder the 8-inch valve in the overflow weir was closed and the sediment basin resumed normal operation. Note - The 8- and 18-inch valves had a small flow of water going through them after they were closed. After 2 or 3 days most of the flow stopped. Note - The 8-inch canal gate in the overflow weir was hard to close. The sliding gate valve seemed to be off center and scraping along one side. With too much force the valve stem bends and may eventually break. Use a hammer to tap the high side of the gate down and the valve should slide easily.
