SITE CONFIRMATION The City of Redmond initially conducted a desktop evaluation of all sites provided by Washington State Department of Ecology (Ecology). The table of sites was downloaded and sorted for Redmond and then by “ORDER” number. The result produced 20 sites within the City of Redmond city limits. Each of the sites’ coordinates were then brought into Redmond’s GIS layer and spatially located. Several sites were not suitable without doing a field visit. Site 798 is located in the Sammamish River. Site 874 is located in/on a building without a stream within 0.5 miles. Site 886 is located in a tributary that does not flow 4‐6 months out of the year. Sites 900 and 977 are located in the midline of Lake Sammamish. Next, a GIS layer was added to the map with all the sites that Redmond has historically sampled and compared locations. Sites 41, 58, 221, 419, 512, 626, 656, 736, and 784 had been monitored for continuous temperature, water quality and/or benthos at a location within 300 meters. In April 2014, all sites, except 798, 874, 886, 900 and 977 were field verified. Three sites were difficult to determine; therefore, on June 25, 2014 Brandi Lubliner and Anne Dettlebach from Ecology, toured sites 459, 512, and 886. They determined that site 512 remains a “maybe” but sites 459 and 886 were not samplable due to flow. The results of the desktop and field evaluations are presented in Table 1. In summary, the list included 7 sites that were to be sampled beginning October 1, 2014. The final 7 sites are listed in Table 2 with the initial and final GPS coordinates. ---PAGE BREAK--- 2 Table 1: Original City of Redmond Sites, Locations, and Notes about Each Location.

Peters Creek is located in the west‐central portion of the City. It enters the left bank of the Sammamish River north of 90th Street. The “west branch” tributary joins the main stem just upstream of NE 87th Street. The upstream portion of the left bank tributary has its headwaters in Grass Lawn Community Park. The entire stream length (21,325 linear feet) is located within the City, and 12,250 linear feet is designated as a Class II stream. An average of 1.9 stormwater outfalls can be found per 1,000 feet along the creek. The Peters Creek watershed is 1,045 acres (1,007 acres of which is located in the City). The watershed is highly developed with predominantly single‐family dwellings. Land cover is predominantly landscaped yards. A high‐flow bypass structure is located on the main stem of Peters Creek at Old Redmond Road. This drainage structure is designed to bypass flows greater than the 2‐year recurrence interval to a separate storm drainage conveyance system that drains directly to the Sammamish River. The intended purpose of this bypass feature is to reduce stream bank erosion caused by high flows in Peters Creek main stem, while maintaining base flows (City of Redmond 2008). This bypass structure generally functions as intended. The City has constructed a variety of other enhancements in the watershed including fish passable weirs at the mouth of Peters Creek, replaced multiple culverts, stabilized channel segments and rehabilitated riparian buffers in several locations. However, there are still many portions of Peters Creek that need rehabilitation. In general, water quality in Peters Creek is compromised due to the high level of development in the watershed. Ecology included the left bank tributary of Peters Creek from the confluence with the main stem upstream to Redmond Way on the 2008 Section 303(d) list as a Category 5 waterbody due to impairment from low dissolved oxygen concentrations, high temperature, and high fecal coliform bacteria concentrations (Ecology 2008c). The median B‐IBI score for Peters Creek based on data collected by the City as part of the Annual Benthic Monitoring study (2002 through 2010) is 20, indicating poor conditions (PSSB 2011). ---PAGE BREAK--- 7 BEAR CREEK Riparian habitat on Peters Creek is fair, and is composed of primarily deciduous species and some coniferous species. Riparian habitat is the highest quality in the ravines in the upper portion of the watershed, but is impacted by roads and development in the lower portion of the watershed (Washington Trout 2005). There is a high level of encroachment (19 percent) into the 30‐foot riparian buffer. There are 10 full barriers to fish passage and 6 other partial barriers throughout the watershed. However, surveys by Washington Trout indicated significant salmonid use. These surveys indicate there are many more fish using Peters Creek than was previously documented (Washington Trout 2005). Bear Creek is entirely a lowland stream system, originating in a large area of forests and wetlands in south Snohomish County and north King County. The Bear Creek watershed represents one of the most important salmonid bearing system in the entire Sammamish River watershed. The Bear Creek watershed covers approximately 32,100 acres (50 square miles). Bear Creek is a right bank tributary of the Sammamish River. With the headwaters located in protected land, Upper Bear Creek has a relatively high level of watershed function resulting from a low impervious surface percentage, few street crossings, and a high level of forest cover and riparian forest. Lower Bear Creek has a moderate level of watershed function, due primarily to higher impervious surface percentage and consequent stormwater impacts, from both poorer water quality and inadequate flow control. Land use in the Bear Creek drainage area within the city limits is highly urbanized with 26 percent of the land used for commercial development. Open space (primarily agriculture) makes up 15 percent of the land use. A portion of Bear Creek is listed as a Category 4A waterbody for high fecal coliform bacteria concentrations, high temperature, and low dissolved oxygen concentrations (Ecology 2008c). As described in Chapter 2: Regulatory Drivers, this category means that a characteristic use is impaired by these pollutants; however, TMDL studies (Ecology 2008a, 2008b) and a water quality implementation plan (Ecology 2011b) addressing these sources of impairment has already been developed and approved by the USEPA. The headwaters of Bear Creek have wide riparian buffers; however, in the lower reaches there is much less forested riparian buffer (LWCS/WRIA8 2005). In many reaches, woody vegetation has been totally cleared right up to the stream edge and development has occurred within the ---PAGE BREAK--- 8 WILLOWS CREEK regulatory buffer (Kerwin 2001). Pursuant to the City’s SMP, buffers of 150 feet are required on either side of Bear Creek west of Avondale Road, and an additional 50‐foot outer buffer is required east of Avondale Road. Willows Creek is located in the west‐central portion of the City, entering the left bank of the Sammamish River north of 95th Street. Willows Creek runs west to east with about a third of its watershed represented by three headwater tributaries that combine at the upper end of a large central wetland. Steep slopes occur along the edge of the plateau at the upper end of the undeveloped central portion of the watershed. Nearly all of the system is piped above the valley walls. It appears that in the past a major tributary joined the main stem of the creek on the left bank near Willows Road. This tributary is currently isolated from the rest of the system, but it may be possible to realign the channel to combine the flows in the future. While the tributary is highly degraded in its lowest reaches, the valley wall reaches generally have broad forested buffers, and fair quality instream habitat. The total stream length is 13,040 linear feet, all of which is located within the City limits and 9,835 linear feet of which is designated as a Class II stream. An average of 1.1 stormwater outfalls can be found per 1,000 feet along the creek. In the 463‐acre watershed for Willows Creek, the dominant land uses are single‐family residential and parks and undeveloped land. The watershed includes a Puget Sound Energy power line right‐of‐way, a generally grassy corridor that also includes the Puget Powerline Trail. Several of the headwater tributaries are located in large protected open space areas upstream of Willows Creek Business Park. Land cover in the watershed is dominated by forest and landscaped areas. A left bank tributary of Willows Creek is listed on the 2008 Section 303(d) list as a Category 5 waterbody for low dissolved oxygen and high fecal coliform bacteria (Ecology 2008c). Willows Creek is also listed as Category 2 waterbody for temperature. However, the mapping for this tributary is inaccurate; the tributary, known as Gun Club Tributary, does not connect with Willows Creek. The Gun Club Tributary is a Class III stream with wooded buffers. All indicators show that the hydrology supporting the Gun Club Tributary is relatively stable. The median B‐IBI score for Willows Creek based on data collected by the City as part of the Annual Benthic Monitoring study (2002 through 2010) is 22, indicating poor conditions (PSSB 2011). Riparian conditions are generally poor in the lower reach, with inadequate tree and shrub cover due to Puget Sound Energy’s policy of preventing tree establishment under their power ---PAGE BREAK--- 9 HIGH SCHOOL CREEK lines. A relatively high level (17 percent) of development is encroaching into the 30‐foot stream buffer. In the upper reach, most of the riparian zone is protected in large NGPEs, large tracts, or utility corridor open space. There are 14 partial fish passage barriers on the middle reach, and one complete barrier at the power line culvert near the headwaters, approximately 5,500 feet upstream of the mouth (Washington Trout 2005). Significant salmonid use has been observed on the main stem (Washington Trout 2005). A few pairs of Coho salmon have been regularly observed spawning in Willows Creek. High School Creek is a right bank tributary of the Sammamish River that is located in the northern portion of the City. A major portion of the upper watershed is located in the City, while the other main tributary as well as the valley portion is located in unincorporated King County. The stream length within the City is 14,650 feet, 8,505 feet of which is designated as a Class II stream. A left bank tributary, Kensington Tributary enters High School Creek near Redmond Woodinville Road. A King County channel relocation project was recently completed on the reach of this tributary, including a culvert replacement under NE 124th Street and rehabilitation of an adjacent wetland. Upstream of the relocation project, the tributary flows through wetlands in a narrow ravine. The main stem of High School Creek flows through a future development project with a short, highly degraded section of the stream. Upstream of this impacted reach, the stream enters a densely forested ravine with a thick understory. There is a 4‐acre manmade pond at the headwaters of High School Creek. The High School Creek watershed is approximately 1,686 acres, of which 635 acres are located in the City. Land use in the City portion of the watershed is predominantly single family residences, which are characterized by large lots that transition to more dense development. While land cover is mostly landscaping, there are significant areas of established forest buffering the streams along steep ravines. Twenty‐seven percent of the watershed within the City is considered EIS. The riparian buffer is in good condition in the channel relocation reach in the valley. The adjacent rehabilitated wetland provides additional buffer. Further upstream, the steep ravine provides a relatively wide riparian buffer of mostly deciduous trees and wetlands with invasive plant species. Near 167th Place NE, the valley becomes less confined and residential development begins to infringe on the riparian buffer (Washington Trout 2005). ---PAGE BREAK--- 10 There are eight fish passage barriers on High School Creek including seven partial barriers and two complete barriers. One complete barrier (a perched culvert) south of NE 116th Street has been replaced with a fish passable culvert. There are additional barriers outside of the city limits. Significant salmonid use has been observed in High School Creek based on Washington Trout surveys (Washington Trout 2005). There are anecdotal reports of Coho salmon using the lowest reach and documented cutthroat trout in the reach through the ravine (Washington Trout 2005). High School Creek has multiple channels with older uncontrolled development contributing runoff to the upper reaches. The upper watershed is mostly developed with low density residential, some of which is under development pressure in the near future. High School Creek also has intact wetlands and forested buffers. ---PAGE BREAK--- 11 Table 3. Summary of Existing Watershed, Fish Use, and Water Quality Conditions for Class II Streams.

Dates, times and results are listed in the Water Quality Index Spreadsheets shown below. Each site was monitored in situ for temperature, pH, conductivity and dissolved oxygen. Grab samples were also collected and sent to AmTest Analytical in Kirkland (fecal coliforms only) and to Manchester Environmental Laboratory (MEL). Analysis of grab sampling by MEL included total phosphorus, ortho‐phosphate, turbidity, total suspended solids, chloride, hardness, ammonia, total nitrogen and nitrate‐nitrite‐N. Peters Creek, Site 158 has a WQI score of 58. The primary reasons for the low score are high fecals in February, and May through September. High phosphorus levels also contributed to a low score. Willows Creek, Site 736 has a WQI score of 62. High temperatures and low dissolved oxygen in July and August affected the score. Additionally, high fecal coliforms in July, August and September lowered the score. Willows Creek near the headwaters, Site 885, has a WQI score of 49. February had a fecal coliform sample of 530 cfu’s and July’s sample had a fecal coliform sample of 300 cfu’s, well above the geometric mean of 50 cfu’s. Total nitrogen and total phosphorus tends to be high in this reach. High School Creek, Site 656, has a WQI score of 51. Low phosphorus, high fecal coliform hits in several months and some high TSS samples contributed to the low score. Gun Club, Site 814 scored 42 on the WQI. Fecal coliforms were high in February (390 cfu’s), May (2600 cfu’s), June (480 cfu’s), July (840 cfu’s), August (410 cfu’s) and September (110 cfu’s). TSS and nitrogen are also factors contributing to the low WQI. Bear at the mouth, Site 512, scored a 42 WQI and suffered from high fecals (610 in February and 920 in July), high nitrogen and elevated temperatures particularly in June with 18.4 C, July with 20.2 C and September with 16.5 C. This site was newly channelized just one month prior to sampling. The riparian zone is immature as is the stream bed. Bear at Swedish Medical Center, Site 626, scored the lowest of all the sites with a WQI of 38. Fecal coliforms were over 100 cfu’s for 6 of the 12 months and were between 50 and 100 for another 2 months. Nitrogen levels are high, temperatures were above 16.5 in June, July and August and total phosphorus is a concern. This reach of Bear is upstream site 512. This site is a slow moving reach through canary grass fields. 13 ---PAGE BREAK--- 14 Table 5a: Water Quality Index (WQI) calculation sheets from Ecology.

Benthos, periphyton, a, sediments and habitat information were collected. Benthos, habitat, and periphyton results were not provided to the City as of December 31, 2015 and thus, will not be found in this report. Table 6: Date and time of beginning of habitat collection. Note that habitat was done over 1 entire day and flagging, benthos, periphyton, waters and sediments may have been collected on another day.

The site is located along the valley in Redmond, flanked by industrial/commercial sites and office parks. Immediately upstream of the sample site is an indoor soccer complex and a gas station. To the north is a car repair shop and warehouse businesses (fitness facility and a commercial paint store). To the south (left bank) is building supply with an active outdoor operation (forklifts, light industrial activities). The riparian ---PAGE BREAK--- 22 BEAR CREEK MOUTH‐SITE 512 zone is narrow and the parking lot and business operations encroach into the 30’ riparian buffer zone. Habitat monitoring started on July 1, 2015. The site had been previously flagged and GPS on June 18th. On July 1, 2015, a team of two people collected benthos, periphyton and sediment and another team of 2 people collected habitat data. The benthic, periphyton and a samples were processed and preserved at the site. The data was collected per the Ecology protocol delineated in Appendix G—QAPP. Once enough sediment was collected, the sample was taken back to the Sammamish River Business Park, City of Redmond Surface Water Quality Laboratory and sieved, processed, labeled and stored. A collection error on this first effort resulted in MEL contacting Redmond and informing that the samples were unacceptable due to too much water and could not be processed. On September 2, 2015 a second, complete set of sediment samples was collected and processed according to protocol. MEL ended up analyzing both samples. MEL explained that once the sample was sieved, that bottles had to settle and the liquid needed to be piped off. For this to occur, the samples had to settle overnight. This resulted in a shift in sample collection for the remaining sites. Logistically, Redmond could no longer take the sediment samples to the MEL locker pickup on the same day they were collected. This extra day would mean water samples would expire. So the new sampling schedule was to collect water one day, sediments on one day and habitat assessment on another. This site is located just upstream of the mouth. In the summer of 2014 about ½ mile of channel was moved further to the south allow for the widening of SR520. Meanders, large woody debris, a newly planted riparian zone and cobble installation were part of the restoration activities. Bear was diverted into this new channel in August of 2014 for the first time. The sampling reach (300m) is located entirely within the site restoration. The sampling site is flanked by SR520 to the south, Redmond Town Center Mall to the north and just upstream are shopping malls, Redmond Way and Bear Creek Parkway. The riparian buffer zone immediately adjacent to the sampling site is greater than 200 ft. but it is immature. Parking lots and business activities encroach on the buffer in the reach immediately upstream. The site was flagged and GPS on July 27, 2015, sediment, periphyton and benthos were collected on July 28, 2015, and habitat assessment was conducted on July 29th. MEL work order are 150738‐ 03 and 1507038‐07. This site was chosen as the duplicate sample, therefore 2 sets of sediment data exist. ---PAGE BREAK--- 23 BEAR CREEK BEHIND SWEDISH MEDICAL CENTER‐SITE 626 HIGH SCHOOL CREEK‐SITE 656 Pesticides were not detected in either sample. Bases/Neutrals/Acids (BNAs) were above the RL for Fluoranthene, Phenanthrene, Pyrene and Retene for sample 150738‐03 and no BNAs were found above the RL for sample # 1507038‐07. Metal results are presented in Table 7 alongside the Washington State Department of Ecology SCUM II for freshwater benthic protection standards for comparison. PCB and PBDE congener laboratory results can be found in the appendices. This reach is of the Bear/Evans confluence and flows through an open field of canary grasses in the upper part of the reach and poplar trees in the section. This channel is slow moving, silted bottom with very little cobble, woody debris or shade. The reach is plagued with Brazilian Elodea and is overgrown with algae. Stream channel is monotonous and there is little diversity. Deer, heron and small birds are often seen in the area. To the north of the site exist a former farm and grass fields. To the south of the site is an office park and medical center. The buffer in the reach is greater than 150’ and has been replanted within the last 10 years. Pockets of homeless encampments have been observed in the area. Site was flagged on July 28th, sediments, benthos and periphyton were collected on August 25, 2015 and habitat survey on August 26, 2015. Three people conducted the habitat survey due to the size of this site. BNA results showed Benzo pyrene, Fluoranthene, Pyrene and Retene above the RL. Dichlobenil results are 0.035 mg/kg. All other pesticides were non‐detectable. Metal results are shown in Table 7. PCB and PBDE congener laboratory results can be found in the appendices. The High School Creek reach site stretches from NE 116th Street upstream 150 meters. The entire reach was rechannelized in 2013 including large woody debris, meanders, riparian planting and other stream complexity enhancements. Many of the large trees within the reach were maintained and thus, the channel is well‐shaded. To the west of the channel is a natural protection easement. To the east is a single family residence that is within 100 feet of the stream. Upstream of the site is a steep ravine that ascends about 100 feet to the hill above. This area is relatively undeveloped due to the steep slopes, but, once on top of the hill, single family residences dominate the landscape. Several large plats have been in some stage of development since 2005. This area of Redmond has experienced a high degree of development over the last decade. ---PAGE BREAK--- 24 Redmond has collected benthos and water quality grab samples on this stream for multiple years and thus, has quite a bit of data on the stream. Stream flows during the summer of 2015 have not been observed to be that low since monitoring began in 2001. Low stream flows created a channeling environment from which to collect grab samples and bugs. The day before grab sampling, a hole deep enough to submerge a 1000 ml sample bottle, was created to facilitate collection. Habitat assessment data and sediment samples were collected on 7/15/2015 under MEL work order # 1507038‐04. Metal and pesticide results are shown in Table 7. PCB and PBDE congener laboratory results can be found in the appendices. Habitat assessment, sediment, benthos, and periphyton were collected on 7/8/2015. A team of 2 people collected the samples while another team of 2 did the habitat assessment. The sampling reach of this Willows site is located about 600 m upstream from the mouth at the Sammamish River. Willow’s headwaters are located on the west side of Redmond around 250 feet in elevation. The stream branches predominately drain single family residential areas and some roads. Willows has very little stormwater influence. As the stream moves from west to east, it hits the valley floor and spreads out into braided channels and wetlands across the Puget Sound Energy easement dominated by grasses. The channel reforms in the business park just west of Willows Road. The sampling reach is located within a Puget Sound Energy power line easement. The properties to the south of the stream are light industrial and encroach into the buffer. A project was completed in the early 2000’s to move Willows from underneath an industrial building. The corner of that building is now within 20 feet of the stream channel. The property to the north of the sampling site is a large church with a giant parking lot. The paved area comes within 20 meters of the stream. A paved walking path is between the stream and the parking lot. The stream is very slow moving through this reach. The slope across the valley floor to the Sammamish River is shallow. Puget Power trims the trees every year and discards the branches in the stream which cause the stream to spread out and go around them. The area immediately upstream floods the streets and parking lots during periods of heavy rain probably due to combined factors of embedded stream bottom, shallow slope and other factors. Metal and pesticide results are shown in table 10 below. PCB and PBDE congener laboratory results can be found in the appendices. WILLOWS AT OVERLAKE CHURCH‐SITE 736 ---PAGE BREAK--- 25 This site is located of a steep ravine, east of Redmond Way. It is located upstream of one of the 3 main branches that contribute to the stream. The site is surrounded by undeveloped land within about 200 meters. Single family homes and roads make up the majority of the development upstream. The riparian buffer zone is relatively intact with mature trees to provide shade. The stream channel has moved around in recent years. Stream flows can be high, allowing for sediment redistribution. Fallen trees and sediment contribute to channel braiding and rerouting. There is human influence in the area as observed by the bicycle jumps that are created and destroyed on the stream bank and several treehouses that have been built over the years. Sediment, benthos, and periphyton were collected on 7/22/2015. PAL had non‐detects for all pesticides except dichlobenil at 0.023 mg/kg. BNA and metal results are shown in Table 7. PCB and PBDE congener laboratory results can be found in the appendices. Gun Club Creek is located in a valley between the Gun Club and single family residential plats. The entire stream upslope from the sampling reach is in a steep ravine and punctuated by errant bullets from the rifle range. The original sample location was in this impossibly located area. In order to gain access and avoid stray gun fire, the sampling location was moved to the first samplable location (about 300 meters). The final sampling location is in a treed buffer area. To the southeast about 100 meters is a large residential development of single family houses. The only other development upstream of the sampling location within 200m is a paved footpath and set of stairs. Immediately to the south is a business park. Gun Club disappears under Willows Road and never resurfaces. This site nearly went dry during the summer of 2015. Sampling holes needed to be carved out of the sediment in order to fill grab sample bottles. This was unusual. Base flows are usually robust for this tributary during summer months. Metal results are shown in Table 7. PCB and PBDE congener laboratory results can be found in the appendices.

All analyses requested were evaluated by established regulatory quality assurance guidelines. Sample Information The samples were received at the Manchester Laboratory on 9/4/2015 and 9/9/2015. The coolers were received within the proper temperature range of 0°C - 6OC. The samples were received in good condition. Two samples were received and assigned laboratory identification numbers 01 and 02. Holding Times The laboratory performed all analyses within their hold times. Calibration The instrument was calibrated following the appropriate method. All initial and continuing calibration verification checks were within the acceptance limits. All initial and continuing calibration verification and blank checks were within the acceptance limits. All standard residuals were within acceptance limits. All r-values were within acceptance limits. ---PAGE BREAK--- The instrument was calibrated with a NIST traceable standard and verified to be in calibration with a second source NIST traceable standard. Oven drying temperatures were monitored before and after drying. Method Blanks No analytically significant level of analyte was detected in the method blank associated with these samples. Laboratory Control Samples All laboratory control sample recoveries were within the acceptance limits. Replicates All associated duplicate relative percent differences of samples with concentrations greater than 5 times the reporting limit were within the acceptance limits. Matrix Spikes All matrix spilce (MS) recoveries were within the acceptance limits except for chromium and zinc. One of the matrix spilce recoveries for chromium and zinc were outside of the acceptance limits. The source sample was from a different work order and was not evaluated. Internal Standards All internal standard recoveries were within the acceptance limits. Other Quality Assurance Measures and Issues U - The analyte was not detected at or above the reported result. bold - The analyte was present in the sample.

All SWG members have interests and a stake in the Puget Sound watershed health and recovery. The SWG was convened by the Puget Sound Partnership (PSP) and the Washington State Department of Ecology (Ecology) in October 2008 to develop a regional stormwater monitoring strategy and to recommend monitoring requirements in National Pollutant Discharge Elimination System (NPDES) Municipal stormwater permits issued by Ecology. In 2012, the SWG became the first “topical workgroup” included in the Puget Sound Ecosystem Monitoring Program (PSEMP), an organization designed to coordinate regional monitoring efforts to assist in providing information to support Puget Sound recovery efforts. An overall strategy for stormwater monitoring and assessment for the Puget Sound region was developed by the SWG in 2010 (SWG, 2010a). This strategy, summarized in Appendix A, included recommendations for status and trends monitoring in small streams in the Puget Sound watershed and in the Puget Sound nearshore, with a focus on an integrated approach to quantify stormwater pollutant impacts in small streams and in Puget Sound, and providing information to inform adaptive management of stormwater to reduce harm to the greater Puget Sound watershed ecosystem. The SWG also recommended a specific NPDES municipal permittee-funded plan for monitoring the effects of stormwater in small streams and nearshore, under the current conditions in the Puget Sound region (SWG, 2010b). The resulting program, a subset of the overall strategy, is called the Regional Stormwater Monitoring Program (RSMP). Specifically, the RSMP includes status and trends monitoring of water quality and "watershed health" (physical habitat, water quality, sediment chemistry, and biological communities) in small streams in the Puget Sound lowlands; and of sediment quality, and mussel contaminants in the marine nearshore of Puget Sound. All the RSMP status and trends monitoring follows a probabilistic design (SWG, 2010a) that is compatible with ongoing status and trends monitoring programs such as Ecology’s statewide monitoring program entitled Status and Trends Monitoring for Watershed Health and Salmon Recovery (WHSR) (Cusimano ct al., 2006). Additional information about the experimental design, the goals, and the objectives for status and trends and other monitoring in the RSMP can be found in Appendix A of this report, in SWG (20l0a and 2010b), and at the RSMP website (http://www.ecy.wa.gov/programs/wq/stormwater/municipal/status.html). This QAPP has been generated to document the City of Redmond’s status and trends monitoring design, independent of the regional status and trends monitoring, as Redmond chose to collect data within Redmond instead of paying into the regional program. This QAPP is a standalone QAPP and documents how the City of Redmond will collect status and trends data that is comparable to the regional status and trends monitoring program. ---PAGE BREAK--- Page 7 Scope of this Quality Assurance Project Plan Ecology issued NPDES municipal stormwater permits for Phase I and Phase II communities (Ecology, 2012a, b) effective August 2013 through July 2018. All permittees located in Puget Sound were given two options to comply with the permits’ Special Condition S8.B for status and trends monitoring requirements. Option 1: Pay a prescribed amount into a pooled fund to support RSMP Status and Trends monitoring. These permittees’ role is limited to providing permit-defined amounts of funding for coordinated implementation of monitoring at sites throughout the Puget Sound region. Or Option 2: Conduct their own status and trends monitoring at specific, assigned sites inside their jurisdictional boundaries, following the same protocols as those used for the RSMP. In fall 2013, the City of Redmond officially selected the Option 2. This Quality Assurance Project Plan (QAPP) defines the permit-required small streams status and trends monitoring that will be conducted by Redmond. This QAPP serves as the Ecology-approved “RSMP QAPP” referenced in the permits. This QAPP defines the site confirmation and sampling protocols that the permittee will follow while conducting the monitoring as well as the data and reports that the city will produce to document the monitoring results. This QAPP was developed in accordance with Ecology’s QAPP guidelines (Lombard and Kirchmer, 2004). City of Redmond Roles and Responsibilities The City of Redmond will conduct monitoring in assigned small streams sites in their jurisdictions. Redmond must submit the completed version of this QAPP to Anne Dettelbach, Ecology permit manager by July 15, 2014 for approval prior to sampling. The key completion dates for Redmond’s required monitoring activities including site confirmation, field and laboratory work, data entry into Ecology’s Environmental Information Management (EIM) database, and submission of monitoring summary reports, are summarized in Table 1. ---PAGE BREAK--- Page 8 Table 1. Key completion dates for permittees' QAPPs, monitoring activities, and reports for status and trends monitoring in small streams.

The City of Redmond is required to participate in a one-day RSMP or Ecology sponsored field-based training (to be held in summer 2015) for sediment and habitat sampling prior to conducting that sampling. Sampling Site Selection and Evaluation The sampling site selection and evaluation process described in this section of the QAPP concerns selecting suitable sites for inclusion in the RSMP based largely on a field visit to candidate sites before the sampling begins. Additional site suitability details that are considered ---PAGE BREAK--- Page 10 on the day of sampling are described in the specific sections of this QAPP detailing the sampling methods. Site Lists Sampling sites within the City of Redmond will be selected from a list of candidate sites referred to as the RSMP Master Sample Site list. Redmond will evaluate and confirm the suitability of sites in numerical order from lowest to highest in the ORDER column. The required numbers of sites to be monitored are stated in permit condition(s) S.8.B.2., which is twelve (12) sites for Redmond. Redmond will select from the list the required number of candidate sites located within their jurisdictional boundaries. The initial 100 RSMP candidate sites (50 for each assessment region) are shown in Figure 1. The remaining candidate sampling sites will serve as replacement sites within Redmond. In the event that any of the candidate sites are found to be unsuitable for sampling, and/or in the event that an insufficient number of candidate sites are located in the permittee’s jurisdiction, the permittee will sample sites from the remaining master sampling site list. If, from the remaining master sampling list, there still is not enough sites suitable for sampling, the permittee will sample only the suitable sites from the list. ---PAGE BREAK--- Figure 1 Initial 100 candidate site locations for the UGA and non-UGA assessment areas In the Puget Lowlands Ecoregion for the RSMP.

City of Redmond small stream candidate UGA sites. ---PAGE BREAK--- Page 13 Site Evaluation Site evaluations, which must include a field visit to a candidate site, will determine the suitability of each site for monitoring to meet the RSMP goals. Site suitability is determined by selection criteria related to accessibility, hydrologic and geomorphic characteristics (flow, physical features, and salinity), and location relative to a candidate sites’ original coordinates. Candidate sites for evaluation are from the Master Sample Site list that was generated for Puget Lowland Ecoregion streams that drain to Puget Sound. Within that area, candidate sites are specified within each of the assessment regions: inside the Urban Growth Area (UGA) boundaries, and outside the UGA boundaries. Site evaluations will begin with the priority list of the initial 100 RSMP candidate sites, with 50 for each assessment region shown in the following “Site Lists” section. If any of those initial candidate sites are deemed unsuitable for monitoring, additional candidate sites for the relevant assessment region will be evaluated in the numerical order listed in the Master Sample Site list (from lowest to highest in the ORDER column). The site evaluation procedure will start well in advance of the sampling season, ideally in March through June 2014, and will continue through the sampling season as necessitated by potential changes in site conditions that affect suitability for sampling. Desktop evaluation of candidate sites will be performed in advance of the initial site evaluation visit, and will include comparing candidate site coordinates to existing information on such items as surficial geology, parcel/property ownership, NHD waterbody type, historical streamflow and /or water quality data, and aerial photographs. Criteria for Selecting a Suitable Sampling Site Selection criteria for determining the suitability of a candidate site for monitoring to meet the RSMP goals are described below. Accessibility Criteria These criteria concern whether access to a site is permitted by the land owners, and if the site can be safely accessed and sampled throughout the year. A site may also be deemed unsuitable, or impracticable, for sampling certain if more than one hour is required to access the site from the nearest parking location. Permission If a candidate site is not obviously accessible through public property, property owners and/or tenants whose property will need to be accessed will, if feasible, be contacted prior to site evaluation. Parcel information gained from the desktop evaluation will be researched and a good faith effort to contact owners or tenants will be made. A site will be deemed unsuitable for sampling if permission has been denied by all land owners, tenants, or resource managers along the entire hydrologic reach (see Location Criteria, below). The Washington State Department of Natural Resources (WDNR, 2010) describes how to discern public and state-owned waters. ---PAGE BREAK--- Page 14 Overall safety conditions for access and sampling will be assessed prior to sampling, based on state and federal law and organizational policy. But it is ultimately the responsibility of the field crew at each time of arrival to decide if it is safe to enter the stream to conduct the sampling. Appropriate reasons for disqualifying a site from sampling may include: • flow is too swifl or too deep; • route of entry is unstable; • hostile people or animals are present. These criteria concern the conditions of the stream and streambed with regard to the specific types of data desired for the RSMP. To be considered a suitable sampling site, the waterbody at the candidate site coordinates must be on a stream or small wadeable river, and not on a lake, pond, wetland, or estuary. Specifically, the waterbody must have: • a net flow of water that is unidirectional; • defined left and right banks readily discernible from mid-stream; • unintemipted surface-water flow for more than half the length of approximately 20 bankfull widths or a minimum of 150 meters surrounding the candidate site coordinates; • perennial flow (as best as can be determined at the time of the site visit); • flow in a natural channel that might have been highly modified, but was not constructed (such as canals, ditches, or pipelines); • natural substrate on the channel bottom; • freshwater, as defined by a water column with more than 95 percent of its depth with less than 1 part per thousand salinity at any time during the year. Multiple lines of evidence may be used to make this estimation vegetation, proximity to a known estuary, or salinity measurement). Location Criteria The following location rules apply such that the site reflects the intended probabilistic stream characteristics. During the site evaluation field visit, the field crew will attempt to access the site at the given coordinates or as nearby as possible, with recognition of the challenges of sampling in urban areas, particularly in gaining access to discretely defined locations. Ideally, a suitable sampling location will be located within 250 meters of the given candidate site coordinates. However, if access, flow, physical, and chemical criteria are not met within this distance, the field crew may continue to investigate locations upstream and of the initial reach with the objective finding a suitable site that maintains the original candidate site characteristics. More specifically, suitable sampling sites upstream and of the candidate site coordinates must fall within these constraints: • the final site is the same size class of the original candidate site; and • there are no continuous surface-water inflows in excess of approximately 25 percent of the flow already in the reach'; and ' During the site confirmation process, questions about a how specific reach is defined should be directed to RSMP Coordinator Brandi Lubliner at [PHONE REDACTED]. ---PAGE BREAK--- Page 15 • either : o there is no substantial, abrupt change in adjacent land use such as from residential to industrial, or from native vegetation to developed conditions; or o the final site is less than 500m from the original candidate site coordinates. The RSMP will determine how to interpret statistically weight) the data from all of the sites sampled by permittees who have chosen to conduct their own monitoring. Documentation of Site Evaluations Redmond must verify all sites given the suitability criteria above. Documentation of observations from both the desktop and field visits will be recorded and provided to the RSMP upon request. Permittees will provide a table listing the decisions and reasons for site selection or disqualification resulting from the site evaluations to the RSMP Coordinator by June 15, 2014. Site Evaluation Results Redmond followed the Criteria for Selection Suitable Sites defined by this QAPP. The results of evaluation has resulted in only seven probable sites, with one of the seven sites likely to have high flows all year around that will make it unsafe for sampling. As required, Table 4 below provides the full list of potential sites, identifies which sites meet the criteria in the sample yes/no column, and (if applicable) the reasoning for disqualifying a site is detailed in the notes column. Figure 3 is a map of sites that have been found suitable for Redmond’s status and trends monitoring. Mid-Study Changes The City of Redmond will make a good faith effort to sample at the selected sites per the QAPP requirements. If a site becomes unsuitable for sampling during the course of the study, the RSMP Coordinator will be notified. Reasons a site may become unsuitable include, but are not limited to: a stream goes dry; the adjacent parcel(s) change ownership, and the new owner does not grant permission; or natural causes such as mudslides or animals make the site no longer safe to access. If suitability conditions change prior to sampling a site for watershed health and sediment chemistry and the site is no longer suitable, then a new RSMP site needs to be identified from the list in order. If suitability conditions change after sampling the site for watershed health and sediment chemistry and the site is no longer suitable, sampling will simply discontinue for this round of RSMP sampling and conditions noted on the site lists. ---PAGE BREAK--- Page 16 ---PAGE BREAK--- Page 17 Table 4.

Suitable Status and Trends Sites in Redmond ---PAGE BREAK--- Page 20 Measurement Quality Objectives Measurement quality objectives for small stream monitoring described here are to obtain and analyze sufficient numbers of high quality samples to meet the goals and objectives of the RSMP status and trends program. Data quality indicators include precision, bias, sensitivity, representativeness, comparability, and completeness (Appendix The biological and habitat indicators adopted for this program come from Ecology’s Watershed Health Monitoring Program for small streams (Adams, 2010a). The adopted water chemistry indicators come from Ecology’s Ambient Water Quality monitoring program (Hallock, 2012), and the adopted sediment chemistry indicators come from multiple monitoring efforts within Ecology (Dutch et al., 2010; Johnson, 2010; and Meredith and Furl, 2008). Field measurements Measurements of water quality, sediment size estimation, and stream habitat variables are taken by field staff during a sample collection event. The City of Redmond must follow the collection methods, reporting requirements, and quality control (QC) procedures summarized in the Field Operations sections of this report. This approach will provide field measurement data that meet measurement quality objectives (MQOs) for status and trends monitoring for small streams under the RSMP, listed in Tables 19 and 20. The City of Redmond will make a good faith effort to collect monitoring data described per QAPP requirements. If a water quality sample or measurement is missed on occasion, a second effort will be made to collect the sample within the same month. If a second attempt is also unsuccessful, then the RSMP Coordinator will be notified, and a third attempt is not required. Reasons a sample or measurement may not be made include, but are not limited to: a stream goes dry; the stream site cannot be accessed due to high flow conditions, vandalism, extreme climatic conditions, or monitoring equipment has a sudden failure. Flow measurements may need to be estimated using high water mark, staff gages, or other estimation techniques during the winter months to minimize exposure to hazardous conditions for staff. Water quality samples and measurements made during very high flows may be made from anywhere within the reach. Laboratory measurements Sediment and water quality laboratory analyses will be conducted at laboratories that have Ecology-accreditation for those analyses, except those noted in Table 5. Ecology’s Laboratory Accreditation Program maintains a searchable database that may be accessed from this website: www.ecy.wa.gov/programs/eap/labs/lab-accreditation.html. (Laboratory methods and reporting limits are listed in the Quality Control section). Unless alternative methods are approved by Ecology in writing, the analytical methods listed per the QAPP shall be used by Permittees when monitoring as required by section S8B.2 of this permit. Any alternative method proposed by the Permittee must have a similar reporting limit or ---PAGE BREAK--- Page 21 must be justiried as adequate for the likely range of concentrations. Permittees are not guaranteed approval of their alternative methods or reporting limits. Taxonomic identification will be conducted by a lab that employs taxonomists certified by the Society for Freshwater Science at the genus level. The taxonomist should have experience with the freshwater macroinvertebrates of the Pacific Northwest. Work performed by the City of Redmond is expected to meet the quality control requirements of the analytical methods stated in this QAPP. These requirements are summarized in the Quality Control section of this document. Laboratory selection Multiple laboratories will be needed to ensure sample completeness. Contracting for laboratories is a responsibility of the permittee. Permittees may consider their own or other permittee’s laboratories, commercial laboratories, or Ecology’s Manchester Environmental Laboratory (MEL). Laboratories for water and sediment parameters will be selected based on their current accreditation status with Ecology (www.ecy.wa.gov/programs/eap/labs/search.html) and their ability to achieve acceptable limits of detection for the parameters measured as part of this project.

This QAPP’s appendices C through F provide detailed procedures for watershed health, water quality monitoring and quality control. Appendix G provides field forms that may be used in the field for data collection. Scientific collection permit Permittees are responsible for obtaining the necessary permits for sampling macroinvertebrates. The scientific collection permit is required by the Washington Department of Fish and Wildlife (ahgo d /1 cens n sc . Permittees are advised that it may take several months to process and acquire these permits. Safety The City of Redmond should develop a site-specific safety plan including at a minimum the following elements. Sampling Field activities should be conducted by at least two people. Activities can be parsed into tasks to be accomplished by one or more persons at a given time. A contact person will be designated at the office to which field personnel report at the end of each day at pre-designated times. Staff must carefully plan field activities and obtain permission to access private land. Staff may also notify the land owner which day they will be sampling. Field and laboratory preservatives Biological samples collected from streams must be preserved immediately following storage in containers. Inadequate preservation often results in loss of prey organisms through consumption by predators, eventual deterioration of the macroinvertebrate specimens, and/or deformation of macroinvertebrate tissue and body structures, making taxonomic identification difficult or impossible. The field preservative used for biological samples is 85% denatured ethanol. The preservative is typically prepared from a stock standard of 95% denatured ethanol. Flammability, health risks, protective equipment, and containment information are listed on warning labels supplied with the preservative container. Detailed information can be found with the Materials Safety Data Sheets (MSDS). Minimal contact with the 95% denatured ethanol solution is recommended. For the water samples, several of the nutrient parameters require field preservation using hydrochloric acid (HCL) or sulfuric acid (H2SO4) (see Table 14). These jars can be ordered with preservative in them, and they must be handled carefully to avoid spilling the preservative during sample collection. ---PAGE BREAK--- Page 24 Equipment and maintenance A list of equipment necessary to complete both watershed health and water quality monitoring field activities is presented in Appendix H of this QAPP. Servicing of scientific instrumentation will follow the instrument manufacturers’ methods and will be conducted as needed. General maintenance will consist of equipment inventories, inspections, testing, and replacement of wom, tom, or missing components. Equipment decontamination and prevention of spread of aquatic invasive species Field work will be conducted and equipment cleaned to prevent the spread of invasive species. Staff practices and equipment that contact multiple surface waters will, at a minimum, be cleaned according to Ecology’s standard operating procedure (SOP) EAP070, Minimizing the Spread of Aquatic Invasive Species (Parsons ct al., 2012). These procedures will be followed at the end of each work day or upon leaving a water body before entering another. Some areas are designated to be of“Extreme Concern”; these areas are shown in several maps at the following link: www.ecy.wa.gov/programs/eap/InvasiveS cies/OAISPublicVersion.html All sediment material not retained for analyses or archiving will be rinsed near the sampling location with stream water. Also, the sediment scoop and bowl will be rinsed on-site. Used equipment will not be used at another site on the day of sampling, unless completely cleaned. Any portion of the sampling equipment (nets, sample container holders, scoops, bowls), filters, or other materials coming into contact with the sample will be decontaminated prior to use or will be certified as pre-cleaned from the equipment source. Sampling equipment and containers will be prepared prior to the sampling event. Otherwise, cleaning will match the purpose of sampling. For example, the kick nets only need to be free of benthic macroinvertebrates, leaves, and sticks and air dried. Nets, buckets, funnels, and other general sampling equipment may be washed or rinsed with tap water and air dried. Water sampling equipment The containers used to collect nutrient samples should be washed in 10% HCl and triple rinsed in deionized water prior to collecting each sample (Ward, 2007a). Sediment sampling equipment The stainless-steel scoops and bowls used to collect sediments for organic analysis need to be properly cleaned using the following procedure. Clean implements will be stored in aluminum foil or polyethylene bags for transport to the field station. Stainless-steel sampling implements, including the spoons, bowls, and stirrers, will be cleaned sequentially: ---PAGE BREAK--- Page 25 i Washing in non-phosphate detergent (Liquinox) and hot tap water. 2. Rinsing with hot tap water. 3. Rinsing with 10% nitric acid (if sampling for metals). 4. Rinsing with deionized water three times. 5. Air drying in clean area free of contaminants. 6. Rinsing with pesticide-grade acetone (if sampling for organics). Air drying in clean area free of contaminants. After drying, equipment will be wrapped in aluminum foil and stored in polyethylene bags until used in the field. Sampling equipment will be dedicated to a single site. Reuse will require cleaning as outlined in the procedure above, which is based on EPA guidelines (EPA, 1990). Labeling samples Labeling is used to identify where and when a sample was collected and the analyze(s) in that sample to be analyzed. Laboratory-prepared bottles will be labeled to identify the cleanliness and/or preservative contents for each bottle. Bottles will be either numbered or pre-labeled to ensure proper handling. Labels will be filled out in pencil or permanent pen, placed on sample containers. Sample labels will contain the following information: • Site name and RSMP SITE_ID • Analysis to be performed • Date and time of sampling • Sample ID or coding information • Sample numbers (1 of 3, 2 of 3, and so on) • Name/initials of field tech performing the sampling This labeling information will be written in the chain-of-custody forms, which are discussed below. Chain-of-custody procedures for samples Chain-of-custody (COC) procedures are necessary to ensure thorough documentation of handling for each sample, from field collection to laboratory analysis. The purpose of this procedure is to minimize errors, maintain sample integrity, and protect the quality of data collected. A COC form will accompany each cooler of samples sent to a laboratory. Individuals who manipulate or handle these samples are required to log their activities on the form. When the laboratory receives a cooler of samples, it will assume responsibility for samples and maintenance of the COC forms. The laboratory will then conduct its procedures for sample receipt, storage, holding times, tracking, and submittal of final data to the responsible parties. Example COC forms for benthic and water or sediment chemistry samples are in Appendix L. ---PAGE BREAK--- Page 26 Holding times and Sample storage for transport Holding times between sample collection and sample analysis in a laboratory are dependent on analysis type and method of analysis. Holding times and methods used are shown in tables 11, 12, 16, 19 and 20). All collected samples will be stored in ice filled coolers during collection of multiple sites. Samples will be delivered to the lab in coolers with ample ice, dry ice or ice packs to keep samples cold and clean from contamination. ---PAGE BREAK--- Page 27 Watershed Health Monitoring This section describes watershed health monitoring which refers to physical habitat, soil chemistry measurements, and biological community characterization. These measurements and samples will be collected once at each site between July l and October 15, 2015. The biological, physical habitat, and sediment chemistry parameters for watershed health monitoring are presented in Tables 6 and 7. The RSMP analysis for and H/S (personal care products and hormones and steroids) in small streams will be conducted on a sub-set of sites, those that number from 0-120 in the “ORDER” column in the master site list available at Ecology’s RSMP website. No suitable sites within Redmond are included in sites ordered 1 — 120. As such, those parameters have been removed from Table 7 below. Table 6.

PCBs include: all 209 congeners. ---PAGE BREAK--- Page 28 Field activities and protocols for watershed health monitoring The field activities and associated data collection protocols required for watershed health monitoring are described below. For each activity, the reader is also referred to specific appendices in this QAPP. The protocols in this QAPP have been tailored to the RSMP and based on Ecology’s ambient biological monitoring program (Adams, 2010a) and Ecology SOPs for measuring physical habitat (Clinton, 2009; Kennedy, 2009; Werner, 2009a,b,c The primary field data and samples collected during watershed health data collection event (DCE) include stream discharge, sediment chemistry, benthic macroinvertebrates, periphyton, and habitat. Water quality and a may also be monitored (as described in the water Quality Monitoring section of this QAPP) during a watershed health DCE, or it may be completed during a separate site visit. One site may be sampled in several workdays by a two-person field team (Table The following activities must be completed in the listed order over the course of several days to avoid damage to biological specimens while sampling sediment or measuring habitat: 1. Site verification and layout 2. Benthos 3. Periphyton and a sample collection 4. Sediment chemistry sample collection 5. Habitat measurements Table 8. Typical daily work flow for a watershed health data collection event. Watershed health monitoring is conducted according to a reach-wide sampling scheme (Hayslip, 2007) that uses equidistant transects set along a stream reach with a length equal to 20 times the bankfull width (10 upstream and 10 at the sample site. Benthos and sediment sampling along the reach are conducted systematically without consideration for habitat type. For example, the sampler might start collecting on the left bank at transect one, move to midstream at transect two and the right bank at transect three, and move back again until 8 square feet have been sampled from randomly chosen transects.

Large woody debris is tallied across the full length of the site, but records are kept for counts between major transacts, on the ThaMeg Data Form. Global Positioning System (GPS) is required at site coordinates (index sation) and at two major transects for small streams (top and bottom of site). Except for GPS coordinates, these measurements can be done anywhere within the site, but near the index station (mid-reach, transect F) is preferred. Field quality control procedures To ensure the quality and consistency of sample collections, equipment maintenance and sample collection protocols described in the appendices of this QAPP will be followed. Sample holding times Holding times are the maximum allowable length of time between sample collection and laboratory manipulation. Holding times are different for each analyte and are in place to maximize analytical accuracy and representativeness. Each sample collected will be packaged in a container and labeled accordingly. The packaged samples will be held in an ice filled cooler. If necessary, the permittee will coordinate with the analytical laboratory to ensure samples can be transported, received, and processed during non-business hours. Sample containers will be transported or sent by the field team to the analytical laboratory, following established sample ---PAGE BREAK--- Page 31 handling and chain-of-custody procedures. At the laboratory, samples may be further divided for analysis or storage. Tables 11-12 list sample volumes, holding times, containers, and preservation requirements for sediment and biological samples collected during a watershed health DCE.

Documentation Field data measurements will be recorded in the field; example field forms are provided in Appendices C, D, and G for biological, habitat, and sediment chemistry monitoring, respectively. These forms are used in other Ecology monitoring efforts, as print documents and taken into the field for recording. At this time, Ecology has developed new electronic field forms and software to improve field documentation for their Watershed Health Monitoring Program with completeness and data entry to the EIM database. The anticipated completion date is spring 2015. Once completed, the software will be freely distributed to the permittees conducting monitoring for the RSMP for use during the 2015 field season for habitat, benthos and sediment sampling. This software and data management are further discussed in the Data Management and Reporting section of this QAPP. While development and distribution of the field software is intended, as a back-up the field forms provided in the appendices can be printed and used. Paper field forms should be printed on water-resistant paper. When completed, these field sheets will be entered into the above mentioned electronic forms at the office, and paper copies will be stored in an organized central filing location. Forms and documentation will include the station visit/maintenance sheet, meter calibration, and chain-of-custody forms. All entries on field documents will be made in pencil or permanent pen and will list the field technician name(s). Any errors or typos will be crossed out and rewritten by the technician who recorded the data. All corrections will be initialed and dated when made. If field sampling or procedural errors are discovered, action will be taken to manage and correct those errors. Corrections may occur with corrective editing, relabeling, or, if warranted, flagging, discarding, and re-sampling. If a consistent error persists, an amendment to the sampling procedures may be required. Watershed environmental health replicate samples Composited benthic macroinvertebrate, periphyton, and sediment field replicate samples will be collected one time for up to 12 samples collected. Field replicates will be collected by splitting composited samples. All field replicates will be labeled similar to other samples, so that the ---PAGE BREAK--- Page 33 sample has its own unique number. These replicate samples will be submitted blind to the laboratory, with all other field samples. Field blanks Field blanks are not required for watershed health monitoring. Table 13.

Measurements and sample collection may be done from a bridge, by wading, or using a stream-side grab method, depending on the size of the stream and access, provided stream water at the specific monitoring location is well-mixed and representative. Water quality parameters that are either measured in the field or in a laboratory are listed in Table 14. Table 14. Water quality-parameters to be monitored.

Field activities for water quality monitoring and appendices within this QAPP that describe the procedures and protocols are shown in Table 15. Protocols for the RSMP water quality monitoring are adapted from Ecology’s Watershed Health and Water Quality Index (WQI) programs are discussed in Appendix D and are based on multiple Ecology SOPs (Ward et al., 2001; Hallock and Ehinger, 2003; Ward, 2007a,b; Hallock, 2012). ---PAGE BREAK--- Page 35 Table 15. Field activities for water quality monitoring and the appendices describing the procedures. Appendix Site verification c-i[' Streamflow measurement c-3 Water-quality measurements and sample collection D ' The site layout part of this appendix is not applicable to a water-quality DCE Seasonal conditions should be considered during site verification, as the water quality portion of the monitoring program will occur over an entire year and may include sampling during inclement weather or high-flow conditions. Field staff must always survey the sample location on the day of sampling for hazards for staff and equipment. The City of Redmond will make a good faith effort to collect monitoring data described per QAPP requirements. If a water quality sample or measurement is missed on occasion, a second effort will be made to collect the sample with the same month. If a second attempt is also unsuccessful, the RSMP Coordinator will be notified, and a third attempt is not required. Reasons a sample or measurement may not be made include, but are not limited to: a stream goes dry; the stream site cannot be accessed due to high flow conditions, vandalism, extreme climactic conditions, or monitoring equipment has a sudden failure. Flow measurements may need to be estimated using high water mark, staff gages, or other estimation techniques during the winter months to minimize the exposure hazardous conditions for staff. Water quality samples and measurements made during very high flows may be made from anywhere within the site reach. Field quality control procedures for water quality monitoring To ensure the quality and consistency of sample collections, equipment maintenance and sample collection protocols described in the appendices of this QAPP will be followed. Sample holding times Holding times are the maximum allowable length of time between sample collection and laboratory manipulation. Holding times are different for each analyte and are in place to maximize analytical accuracy and representativeness. Each sample collected will be packaged in a container and labeled accordingly.

Field instrument quality control In order to maintain the highest degree of data quality, field equipment will undergo routine cleaning, calibrations, and maintenance at the recommended frequency specified by each manufacturer and described in SOPs. Appendices B and F discuss field meters. Documentation Field data measurements will be recorded in the field. The software being developed for Watershed health monitoring will also be able to record any in-situ water quality measurements. As previously mentioned in the Documentation section for watershed health monitoring, staff will need to prepare paper field forms in case the software is not ready in time for the October 2014 start date. Appendix M contains an example field form to record in-situ water quality measurements made at each site. Forms and documentation will include the station visit/maintenance sheet, meter calibration, and chain-of-custody forms.

Any errors or typos will be crossed out and rewritten by the technician who recorded the data. All corrections will be initialed and dated when made.

If a consistent error persists, an amendment to the sampling procedures may be required. Composite/grab field replicate samples A field quality control schedule is shown in Table 17. Grab and composited field replicate samples will be collected at a rate of 10% of the total samples collected for monitoring under the permit. Field replicates will be collected by splitting composited samples or by collecting additional grab samples. Parameters measured in the field sample also will be measured in the replicate sample for that particular site. All field replicates will be labeled similar to other samples, so that the sample has its own unique number. These replicate samples will be submitted blind to the laboratory, with all other field samples. Field blanks The termJefd blanks includes equipment rinsate blanks, trip blanks, transfer blanks, or specific equipment blanks. Blanks serve as field audits to measure contamination. A single transfer blank for water-based parameters will be labeled with unique numbers and will accompany the first set of samples to the laboratory. If field blank contamination is discovered, additional field blank samples may be used to determine the source of the contamination. Field blank samples collected to determine the contamination source may include: • A field equipment blank collected from the filtration apparatus used to filter orthophosphate. • A field transfer blank collected by pouring lab-provided deionized water into a clean sample bottle to determine whether field contamination is present, unrelated to the equipment. • A field trip blank collected by transporting unopened bottles containing organic and metal- free, certified clean water from the laboratory into the field, and then returned it to the laboratory (bottles are not opened in the field). Trip blanks are used to determine whether any contamination occurs while traveling from field to laboratory. Any field blank contamination will be reviewed by the field lead to determine if samples associated with the field blanks should be qualified based on the contamination. Sample results will be flagged with a if they are less than, or equal to, 5 times the field blank concentration. ---PAGE BREAK--- Page 38 Table 17.

Field QC procedures were previously described as part of the Field Operations sections of this QAPP. QC will be monitored throughout the duration of the study. The quality of raw, unprocessed, and processed data is subject to review according to established protocols in the Measurement Quality Objectives section of this QAPP. Biotic samples QC procedures for biotic samples are currently limited to field replicates precision and laboratory duplicates for accuracy for benthic macroinvertebrates and periphyton. Contract laboratories will make every effort to ensure accurate identification of specimens. More information on laboratory QC procedures is provided in Appendix F-2 and F-3. Water and sediment samples This section discusses QC procedures that will be implemented by the contracted analytical laboratory to provide high quality chemical and physical analyses that meet these QAPP requirements. Contract laboratories will make every effort to meet sample holding times and target reporting limits for all parameters. Laboratory QC procedures and results will be closely monitored throughout the duration of the permit-mandated sampling. The quality of laboratory data is subject to review via the established protocols in the Measurement Quality Objectives section. A typical schedule for laboratory QC samples is shown in Table 18 and, at a minimum, includes: • Laboratory duplicates • Matrix spikes • Matrix spike duplicates • Method/instrument blanks • References (lab standards/surrogate standards/internal standards) ---PAGE BREAK--- Page 40 Table 18.

Instrument calibration The used by the chosen laboratories will meet or exceed manufacturers’ specifications for use and maintenance. Maintenance of this equipment will be conducted in a manner specified by the manufacturer or by the QA guidelines established by the chosen laboratory. Duplicate/splits Laboratory duplicate samples will be analyzed regularly to verify that the laboratory’s analytical methods are maintaining their precision. The laboratory should perform “random” duplicate selection on submitted samples that meet volume requirements. After a sample is randomly selected, the laboratory should homogenize the sample and divide it into two identical “split” samples. To verify method precision, identical analyses of these lab splits should be performed and reported. Some parameters may require a double volume for the parameter to be analyzed as the ---PAGE BREAK--- Page 41 laboratory duplicate. Matrix spike duplicates may be used to satisfy frequencies for laboratory duplicates. Matrix spikes and matrix spike duplicates Matrix spike samples are triple-volume field samples (per parameter tested) to which method- specific target analytes are added or spiked into two of the field samples, and then analyzed under the same conditions as the field sample. A matrix spike provides a measure of the recovery efficiency and accuracy for the analytical methods being used. Matrix spikes are typically analyzed in duplicate (matrix spike/matrix spike duplicate [ms/msd]) to determine method accuracy and precision. Matrix spikes will be prepared and analyzed at a rate of 1 pair/20 (five percent) samples collected or one pair for each analytical batch, whichever is most frequent. Use of ms/msd at the frequency of 5% of the total number of samples is common practice. For the purposes of permit monitoring, these frequencies meet the expectations. Blanks and standards Laboratory blanks are useful for instrument calibrations and method verifications, as well as for determining whether any contamination is present in laboratory handling and processing of samples. Laboratory standards Laboratory standards (reference standards) are objects or substances that can be used as a measurement base for similar objects or substances. In many instances, laboratories using digital or optical equipment will purchase from an outside accredited source a solid, powdered, or liquid standard to determine high-level or low-level quantities of a specific analyte. These standards are accompanied by acceptance criteria and are used to test the accuracy of the laboratory’s methods. Laboratory standards are typically used after calibration of an instrument and prior to sample analysis. Surrogate and internal standards Surrogate standards are used to process and analyze extractable organic compounds (PAHs, phthalates, and pesticides). A surrogate standard is added before extraction, and it monitors the efficiency of the extraction methods. Internal standards are added to organic compounds and metal digests to verify instrument operation when using inductively coupled plasma mass spectrometry (ICP-MS) analysis. Method blanks Method blanks are designed to determine whether contamination sources may be associated with laboratory processing and analysis. Method blanks are prepared in the laboratory using the same reagents, solvents, glassware, and equipment as the field samples. These method blanks will accompany the field samples through analysis. Instrument blank An blank is used to “zero” analytical equipment used in the laboratory’s procedures. Instrument blanks usually consist of laboratory-pure water and any other method-appropriate reagents, and they are used to zero instrumentation. ---PAGE BREAK--- Page 42 Inter-laboratory comparison There is a recognized need to conduct an inter-laboratory comparison study if multiple laboratories are used for the RSMP and permittees conducting monitoring under this QAPP. Permittees will collect replicate samples to support this comparison as follows: Water and sediment replicate samples collected under the RSMP and this QAPP will be sent to two of the participating laboratories. Under this QAPP for permittees conducting monitoring, the contracted laboratory will be sent one of the replicates, and the other replicate samples will be sent to the other determined by the RSMP. Since the laboratories used by the Redmond and the RSMP are the same, then the inter-laboratory comparison requirement is nullified. This inter-laboratory comparison does not apply to the fecal coliform samples. Measurement quality objectives (MQOs) for laboratory samples This section refers to the MQOs, the acceptance thresholds for water data collected under the Water Quality Index monitoring, and sediment data collected under Watershed Health monitoring. MQOs specifically are used to address instrument and analytical performance. MQOs established for stormwater permit monitoring are based on guidance from multiple sources, including EPA, Ecology, and laboratory experience. Tables 19 and 20 represent how data will be verified prior to reporting results. Failure to meet the MQOs may result in data being qualified or rejected. ---PAGE BREAK--- Table 19.

All data will be managed and stored by the permittees. Post- processed data will be finalized and incorporated into annual reports and electronic reports. Reports and data will be submitted to Ecology in the format required. Field data Permittees will need record field water quality and watershed health data using field forms. If necessary, paper field forms should be printed on waterproof paper and kept in a three-ring binder during sampling. Ecology intends to provide to permittees electronic field data collection software that will assist permittees to assure completeness in the field for benthos and habitat monitoring, and with loading this data to Ecology’s Watershed Health database in EIM. Because timing (anticipated completion date of spring 2015) of the software development may not suit monitoring needs under this QAPP, recording on field forms is required. Laboratory data Chemical and bacteria laboratory data will be sent to the permittee from each laboratory following analysis. Reporting times may vary depending on holding time but should not exceed six months of the documented sampling date. Laboratory reports will be reviewed by the permittees for errors or missing data; permittees may implement corrective actions. Finalized electronic laboratory data will be loaded to Ecology’s EIM database by permittees and saved in the permittee’s data file. Data storage All field forms, photographs, electronic data, and laboratory electronic or printed data generated for this project will be stored by the permittees in an organized filing system for electronic or paper files. These files may be sought by Ecology within the permit term. Location, measurement, and sample result data will be evaluated through the data verification process, outlined earlier in this QAPP. Acceptable results will be used by scientists to prepare a summary report and entered into Ecology’s EIM database. Benthos data will be loaded into King County’s Puget Sound Stream Benthos database as well as the Watershed Health section of Ecology’s EIM database. Periphyton data, habitat data, and any field-measured data will be entered into the Watershed Health section of EIM. Page 47 ---PAGE BREAK--- Data Verification and Usability Data verification Data verification involves examining the data for errors, omissions, and compliance with qJiality control (QC) acceptance criteria. Field staff will verify field results after measuring and before leaving the site. They will keep field notes to meet the requirements for documentation of field measurements. The field lead will ensure that field data entries are complete and error-free. The field lead also will check for consistency within an expected range of values, verify measurements, ensure measurements are made within the acceptable instrumentation error limits, and record anomalous observations. The project manager will verify field data to ensure that: • Data are consistent, correct, and complete, with no errors or omissions. • Results of QC samples accompany the sample results. • Established criteria for QC results were met. • Data qualifiers are properly assigned where necessary. • Data specified in the Sampling Process Design were obtained. • Methods and protocols specified in this QAPP were followed. The project manager at the taxonomic laboratory will verify all taxonomic results, and the laboratory will verify all analytical results prior to reporting. Corrective actions for inadequate data If discrepancies in the data are found, there are two options for correction, depending on when the problem is identified. 1. If the problem in identified before the end of the index period (July I to October 15), a review of the protocols and SOPs outlined in the appendices of this document is required. After this review, a repeat site visit may be made to re-collect the sample. This may occur if the data set is incomplete or incorrectly collected. Due to the inter-related nature of chemical and biological conditions, problems identified in the chemical or biological data should be addressed by again collecting the entire suite of chemical and biological analyses parameters. Because the habitat is mostly constant within an index period, if the data in question is related to habitat, only the missing habitat information needs to be collected. Before the second sampling, the investigator must review the SOPs and the appendices of this document to understand the protocols. Equipment should be cleaned and recalibrated and checked for proper function. 2. If the problem is identified after the index period, the data should be flagged and the problem explained in a comment in the database. This will allow the Ecology investigator, as well as external users of these data, to know how these data may be used in projects. lf the data are Page 48 ---PAGE BREAK--- Page 49 incomplete, or if some data standard was not met, the data will not be used to meet the objectives of the study design. Data usability assessment Data usability assessment follows verification. This involves a detailed examination of the data package using professional judgment to determine whether the quality objectives have been met. The project manager examines the complete data package to determine compliance with procedures outlined in the QAPP and SOPs. The project manager also ensures that the MQOs have been met and determines if the quality of the data are usable for the project objectives. ---PAGE BREAK--- Page 50 Stream Monitoring Reports An annual report is required to provide a summary of the previous year’s monitoring activities and results. A detailed monitoring report is due to Ecology as an attachment to the permittee’s annual report due on March 31 of each year 2016, 2017, and if needed, 2018. Annual reports require a Gl9 signature. The stream monitoring report will include a complete discussion of the monitoring effort. The report must include: • Site selection confirmation documentation, • Summary of monitoring activities for water quality index, habitat, benthos and sediment chemistry, and • A cumulative water quality and watershed health results summary for each site. Table 21 outlines the required monitoring report elements. These monitoring reports shall be submitted electronically, as MS Word documents. Table 21. Repordng requirements.

Documentation Field data measurements will be recorded in the field; example field forms are provided in Appendices C, D, and G for biological, habitat, and sediment chemistry monitoring, respectively. These forms are used in other Ecology monitoring efforts, as print documents and taken into the field for recording. At this time, Ecology has developed new electronic field forms and software to improve field documentation for their Watershed Health Monitoring Program with completeness and data entry to the EIM database. The anticipated completion date is spring 2015. Once completed, the software will be freely distributed to the permittees conducting monitoring for the RSMP for use during the 2015 field season for habitat, benthos and sediment sampling. This software and data management are further discussed in the Data Management and Reporting section of this QAPP. While development and distribution of the field software is intended, as a back-up the field forms provided in the appendices can be printed and used. Paper field forms should be printed on water-resistant paper. When completed, these field sheets will be entered into the above mentioned electronic forms at the office, and paper copies will be stored in an organized central filing location. Forms and documentation will include the station visit/maintenance sheet, meter calibration, and chain-of-custody forms. All entries on field documents will be made in pencil or permanent pen and will list the field technician name(s). Any errors or typos will be crossed out and rewritten by the technician who recorded the data. All corrections will be initialed and dated when made. If field sampling or procedural errors are discovered, action will be taken to manage and correct those errors. Corrections may occur with corrective editing, relabeling, or, if warranted, flagging, discarding, and re-sampling. If a consistent error persists, an amendment to the sampling procedures may be required. Watershed environmental health replicate samples Composited benthic macroinvertebrate, periphyton, and sediment field replicate samples will be collected one time for up to 12 samples collected. Field replicates will be collected by splitting composited samples. All field replicates will be labeled similar to other samples, so that the ---PAGE BREAK--- Page 21 must be justified as adequate for the likely range of concentrations. Permittees are not guaranteed approval of their alternative methods or reporting limits. Taxonomic identification will be conducted by a lab that employs taxonomists certified by the Society for Freshwater Science at the genus level. The taxonomist should have experience with the freshwater macroinvertebrates of the Pacific Northwest. Work performed by the City of Redmond is expected to meet the quality control requirements of the analytical methods stated in this QAPP. These requirements are summarized in the Quality Control section of this document. Laboratory selection Multiple laboratories will be needed to ensure sample completeness. Contracting for laboratories is a responsibility of the permittee. Permittees may consider their own or other permittee’s laboratories, commercial laboratories, or Ecology’s Manchester Environmental Laboratory (MEL). Laboratories for water and sediment parameters will be selected based on their current accreditation status with Ecology (www.ecy.wa.gov/programs/eap/labs/search.html) and their ability to achieve acceptable limits of detection for the parameters measured as part of this project.
