Page 1 of 1 EXHIBIT A SCOPE OF WORK February 23, 2004 Mr. Scott Nutter City of Auburn Public Works Department, Engineering Division 25 West Main Auburn, WA 98001 Re: Scope of Work and Budget for Wetland Mitigation Monitoring South 27ih Street Reconstruction (Contract AG-C-220; Task: SA-PR562-001 ) Shapiro Project Number 1035016.1T Dear Scott: In response to the City of Auburn's (City) request, Shapiro and Associates, Inc. (SHAPIRO) is pleased to provide the following proposed scope of work and budget for wetland monitoring. The approach reflected in the scope is based on requirements defined in the Final Wetland Mitigation Plan for the South 277th Street Reconstruction, Phase I project prepared by Herrera Environmental Consultants (April 2001). The plan addresses four mitigation areas. These include the Floodplain Mitigation Site, two areas at the Goedecke North Site, and the Mill Creek Site. The plan states that vegetation monitoring will be conducted in years 1, 2, 3, and 5 at the Floodplain Mitigation Site and in years 1, ;~, 3, 5, 7, and 10 at the Goedecke North Sites and the Mill Creek Site. As you reqLlested, SHAPIRO's role will involve Year 1 monitoring at all four sites. It is understood that monitoring during subsequent years would be subject to future work authorizations under the City's consultant selection process. In developing this scope of work and budget, the following assumptions were made: (1) monitoring will occur during the 2004 growing season; (2) all required. permit approvals for the work have been received from regulatory agencies; (3) site access approvals will be provided to SHAPIRO in advance of the work, and (4) monitoring will be based on requirements in the Final Mitigation Report for the South 277th Street Reconstruction, Phase I project (Herrera, April 2(01), and project as-built plans. Requirements for Standards of Success, Monitoring of the Mitigation Site (Methods), Plant Coverage, Water Regime, and Reporting from the Final Mitigation Report (Herrera, April 2001) are included below. - -.-.----'" _.._-_....._~- ---..-- Mr. Scott Nutter February 23, 2004 Page 2 SCOPE OF WORK The approach for implementing the scope of work is described und'9r the following tasks. For each task, the nature of work, anticipated level of effort, assumptions, and deliverables are described. Unforeseen site conditions, additional or changing regulatory considerations, or other factors that result in the need for a greater magnitude of effort related to these or other new tasks will require the development and approval of a contract amendment prior to conducting such work. TASK 1 - PROJECT MOBILIZATION Based on the initial Task (#SA-PR562-001) request from the City under this on- call services contract (#AG-C-220), two SHAPIRO staff will participate in a half-day reconnaissance inspection to the four mitigation sites with the City's project manager and will review as-built drawings for the planting plans at the respective sites. Assumptions: . The City will provide SHAPIRO with advanced authorization to access the project site, and any adjacent private properties as required. . Monitoring work will be based on documents provided by the City to SHAPIRO on January 27, 2004. Deliverable: . None. TASK 2 - VEGETATION MONITORING Task 2.1 - Planting InsDection When notified by the City to do so, SHAPIRO staff will conduct a one-day site visit to inspect replacement plantings at the mitigation sites. The plant inspections will be conducted to ensure nursery stocks are of suitable quality and that supplemental planting efforts are successfully implernented. It is anticipated the inspection will be conducted in March 2004; however, the exact date will be determined by the City. Assumption: . Two site visits of up to 16 hours will be conducted to inspect replacement of dead plants. ---_._-------_._~,----- -- - - - ---- ----.-. -'~-,-' ._---,-- Mr. Scott Nutter February 23, 2004 Page 3 Deliverables: .

Shrub and tree plantings should cover a minimum of 20 to 30 percent of the ground 1 year after planting, 30 to 40 percent after 2 years, 40 to 50 percent after 3 years, and 50 to 75 percent after 5 years. Areas hydroseeded with grass and emergent species should consist of at least three species that have a combined percent cover of 1 S to 30 percent after 1 year, 30 to 45 percent after 2 years, 45 to 60 percent after 3 years, and 80 percent at the end of the fifth year. Invasive species such as reed canarygrass, soft rush, and Himalayan blackberry should not recolonize more than 15 percent of th'9 restored wetland during each monitoring event over the 5 year period. In the portion of the Goedecke North mitigation site where invasive species will be removed and cleared areas will be replanted (Zone A), the following performance standards will be used to determine whether the mitigation goal and objectives are met: Soil saturation in Zone A of the enhancement wetland with elevations below 62 feet should be within 12 inches of the ground surface for more than 20 percent (50 consecutive days) of the growing season (between March 1 and October 31). Emergent plantings should consist of at least three species that have a combined percent cover of 15 to 30 percent after 1 year, 30 to 45 percent after 2 years, 45 to 60 percent after 3 years, and 80 percent at the end of 5 years, 90 percent after 7 years, and 100 percent after 10 years.

Invasive species such as reed canarygrass, soft rush, and Himalayan blackberry should not recolonize more than 15 percent of th,~ enhanced wetland during each monitoring event over the 10 year period. The primary mitigation goal at the Mill Creek site near the detour route is to create 0.29 acres of riparian wetlands lining the banks of Mill Creek. The following performance standards will be used to determine whether the mitigation goal and objectives at this site are met: Soil saturation in the created wetland with elevations below 42 feet should be within 12 inches of the ground surface for more than 20 pE~rcent (50 consecutive days) of the growing season (between March 1 and October 31).

The goal of monitoring for the floodplain mitigation west site is to determine if the restored wetland is functioning successfully Civer as-year period. The basic goal of monitoring the two wetland mitigation sites is to ensure the successful functioning of the wetlands over a 1 O-year period. Post-construction monitoring of the floodplain mitigation west site will be conducted in years 1, 2, 3, and 5 during the peak growing season (May to August), commencing the first season after construction work is completed. Post-construction monitoring of the two wetland mitigation Sitl~S will be conducted in years 1, 2, 3, 5, 7, and 10 during the peak growing season (May to August), commencing the first season after construction work is completed. Data will be collected to quantify plant survival and condition, plant coverage, and water regimes at these mitigation sites. Plant coverage Evaluation of the percentage of plant coverage in the floodplain mitigation west site and the Goedecke North and Mill Creek mitigation sites is based on the performance standards stated for specific years of monitoring. These performance standards will be applied during the designated monitoring periods for each class of vegetation. Representative sampling at the mitigation sites along transects will be used to estimato the overall coverage of plants. Vegetation coverage will be evaluated during the summer when foliage is in full development. Permanent sampling locations for quantitative sampling of plant coverage will be located along a topographic gradient to note the effects of hydrology on plant growth. Along each transect, the coverage percentage of tree, shrub, and emergent species will be evaluated within a 5-meter-wide swath. Instead of evaluating emergent cover over the entire 5 meter swath, however, subsampling of emergent species within one-square-meter plots will be conducted subject to approval by regulatory agencies. This is a less intensive but equally effective method of monitoring herbaceous species such as emergents, and provides a quantitative rather than qualitative measurement of coverage and performance. The percentage of invasive species (reed canarygrass, soft rush, and Himalayan blackberry) coverage will also be estimated. Dated photographs will be taken of the vegetation along these transects from permanent photo-locations at the time plant coverage is recorded. Transect locations will be shown on the as-built drawings. It is anticipated that two transects will be established in the floodplain mitigation west site. It is anticipated that a total six transects will be established in the ~ -- -------^---_._-----_.._...._.._---------~_.._--_.__.~. - .-.--_._- --- .-.-..- Mr. Scott Nutter February 23, 2004 Page 9 Goedecke North mitigation site (four transects in Zone A and two in Zone B). It is anticipated that two transects will be established in the Mill Creek mitigation site. The performance standards for percent coverage of shrubs and trees within the two wetland mitigation sites, may be adjusted during the first three years of monitoring to account for the phased planting of the tow conifer species. Water Regime Monitoring of hydrology at the floodplain mitigation west site cmd the two wetland mitigation sites is designed to assess whether the pe1rformance standards are met. Two methods will be used to record water depths and soil saturation at each site. This includes a combination staff/crest gauge to record water depths and ground water wells to record depths of soil saturation. Monitoring of water levels in Mill Creek will require installation of a combination staff and crest gauge at both the Goedecke North and Mill Creek mitigation sites. These gauges will be installed in the Mill Creek channel to record the current water level elevation during monitoring events and the highest flood elevation of the previous year. A surveyed benchmark will be used to determine elevations on these gauges. Water level elevations in Mill Creek within the Goedecke North and Mill Creek mitigation sites will be recorded and correlated with rainfall n~cords and available stream gauge data. The sampling method for duration of saturation in the top 12 inches of the soil is slightly modified in this scope of work relative to the continuous monitoring system described in the Final Mitigation Report (Herrera, April 2001). Because of the slow change in ground water hydrologic conditions, repeated measure will be used to provide a quantitative record of the duration of soil saturation. A groundwater well will be used to record soil saturation depth (I.e. depth to standing water) and maximum level of standing water (I.e. as shown by cork dust) in a well at the floodplain mitigation west site and the two wetland mitigation sites. These data will be collected once every two weeks for at least 50 days beginning on March 1, 2004. These data will be used to provide a record of the consecutive days that the soil was saturated within 12 inches of tho ground surface. One well will be used at each site in a representative areas to determine if the performance standard is met. Ground water wells will also be installed at the floodplain mitigation west site and the tow wetland mitigation sites to provide data on the current depth of soil saturation within representative areas of each site. These ground water wills consist of a perforated pipe surrounded by sand that extends at least 16 inches below the ground surface. These ground water wills will be used to monitor soil saturation within 12 inches of the ground - ----~-_._-~----_._--_.._.__.~_._--~----,_._.-._._._._..-.'.. ------- Mr. Scott Nutter Februa';j 23, 2004 Page 1 surface during the growing season to determine whether the performance standards are met. A surveyed benchmark will be used to determine the elevations of these ground water wells. This data will augment the ground water well data collected every two weeks through the 50 day period. Within the floodplain mitigation west site, a total of two grouna' water wells will be installed to record water table elevations. Within the Goedecke North mitigation site, a total of six ground water wells will be installed in Zones A and B to record water table elevations. Within Zone A of the Goedecke North mitigation site where invasive species will be removed, four ground water wells will be installed where the ground surface elevation is 62 feet. Two ground water wells each will be installed in representative areas on both sides of the Mill Creek channel in order to determine whether the soil is saturated within 12 inches of thl3 ground surface. Within ZDne B Df the Goedecke NDrth mitigation site where supplemental planting will Dccur, two ground water wells will .be installed in representative areas along a topDgraphic gradient. MonitDring Df soil saturation in the Zone B area will provide qualitative information about plant survival and conditiDn, rather than determining whether performance standards are met.
