Todd Black will send you a plant selection list for the detention facility. Street Tree Selection: 'Summer Sprite' Linden, Tilia cordata 'Halka' (only commercially available linden that can be used beneath overhead power lines for this location). This linden tree variety will match up with future Hawk's Landing plans. Number of Street Trees - I physically measured approximately 430 feet from the end of the bridge (to south) to the entryway of Barbee Mill development - the approximate point at which the power lines cross the road. At a 40-foot on - center spacing, that would be approximately 11 trees. The exact location of each tree to be marked by myself once the project has been fully constructed with planting to follow, by others. Groundcover - shall be turf in sod form. Sod shall be non -netted only (City will reject netted sod) and comparable to our standard from Emerald Turfgrass Farms. Irrigation in Planting Strip - shall be controlled by the Sentinel Computerized Controller. Signal has to be verified from site to City Hall prior to installation/purchase. Additional transmitting equipment may be necessary to establish communication to base station located within City Hall. Irrigation should be designed for turfgrass, no separate heads or system required for street trees. Irrigation inside of sidewalk area - should be a temporary system that remains for three years then removed. It should tie-in to and operated by the permanent Sentinel system in the planting strip. Detention Facility should mimic a natural form when completed. As an example, the Parks & Recreation Facility in Sea- Tac has this type of design (see photo attached - also, note art). Another example to refer to is the detention facility near the Federal Reserve Bank on SW 27th Street. Suggested Landscape Architects for designing all of the above (however, we have no particular preference): Steve Worthy and Associates, Calvin Jordan and Kate Day. Please have the LA selected contact me directly on the landscape design and construction specifics.

DESIGN - BUILDERS 9 May 3,2010 - REV 0 Appendix 3 Bioretention Plant List The following table includes both native and non-native plant species commonly available in the Puget Sound region and suitable for bioretention cells and swales. Individual site characteristics and goals may exclude some species or require modifications or additions to plant suggestions provided here. Bioretention cells and swales generally feature three planting zones characterized by soil moisture and periodic inundation. Zone 1: Area of periodic or frequent standing or flowing water. Zone 1 plants will also tolerate the seasonally dry periods of summer in the Pacific Northwest without extra watering and may also be applicable in zone 2 or 3. Zone 2: Periodically moist or saturated during larger storms. Plants listed under Zone 2 will also be applicable in Zone 3. Zone 3: Dry soils, infrequently subject to inundation or saturation. This area can be used to transition or blend with the existing landscape. Special Considerations Drought tolerance —Several plants included on the list do not tolerate dry conditions. For these plants, irrigation will be necessary during dry periods. In general, all plantings require watering during dry periods for the first two or three years after planting until established. Placement of large trees —Consider height, spread, and extent of roots at maturity. Use caution in plant selection for areas with under -drain pipes or other structures. Lower limbs of plants placed close to a road or driveway may cause problems with visibility or safety. See Appendix 1: Street Trees for more information on tree selection and placement suggestions. Phytoremediation—Appendix 5 includes a list of plants that have been studied for their ability to filter, absorb, and/or degrade specific contaminants. While most of these plants are not included in the following lists, varieties of some of the species known for phytoremediation are listed. 185 11111- ZONE I * denotes native species TREES SPECIES/ MATURE SIZE/ COMMON NAME EXPOSURE SPREAD TIME OF BLOOM COMMENTS Alnus rubra* Sun/partial shade 30-120 feet/ Prefers moist, rich soils, highly adaptable, Red alder 25 ft. spread drought tolerant;

A lined depression filled with an organic soil mix and wetland vegetation can be an attractive method for promoting evaporation and transpiration of collected runof A functioning bog garden generally displays no standing water, but soils are saturated much of the time, necessitating facultative wetland plant selections. To select plant species appropriate for a bog garden refer to those listed in this appendix, Zone 1, as well as those found in the following table. The list below includes additional native and non-native plant species (not listed in the bioretention plant list) that have been successfully applied in Pacific Northwest bog gardens. It may be necessary to provide additional water to the bog system during seasonal dry periods due to a lack of stormwater runoff. As with any system, plant species in a bog garden setting have various preferences for moisture and sun. Check listed comments below and research plant needs to optimize growth in the conditions specific to individual bog garden systems.

H:\CED\Data\Forms-Templates\Self-Help Handouts\Planning\treeslist_march2010.doc P. 11 6.3.2 WET BIOFILTRATION SWALES 6.3.2 WET BIOFILTRATION SWALES A wet biofiltration Swale is a variation of a basic biofiltration swale for use where the longitudinal slope is slight, water tables are high, or continuous low base flow is likely to result in saturated soil conditions. Where saturation exceeds about 2 weeks, typical grasses will die. Thus, vegetation specifically adapted to saturated soil conditions is needed. Different vegetation in turn requires modification of several of the design parameters for the basic biofiltration swale detailed in Section 6.3.1 (p. 6-39). Applications Wet biofiltration swales are applied where a basic biofiltration Swale is desired but not allowed or advisable because one or more of the following conditions exist: • The swale is on till soils and is downstream of a detention facility providing Level 2 or 3 flow control. • Saturated soil conditions are likely because of seeps or base flows on the project site. • Longitudinal slopes are slight (generally less than 2 percent). z Consult the water quality menus in Section 6.1 (p. 6-3) for information on how this facility may be used to meet Core Requirement #8. 6.3.2.1 METHODS OF ANALYSIS Wet biofiltration swales use the same methods of analysis as basic biofiltration swales (see Section 6.3.1.1, p.6-40) except the following step is added: Step 7: Adjust for extended wet season flow. If the swale will be.downstream of a derPnt,car�,'a providing Level 2 or 3 flow control, multiply the treatment area (bottom width times length) of the swale by 2, and readjust the swale length, if desired. Maintain a 5:1 length to width ratio (see criteria under "Swale Geometry" below). Intent: An increase in the treatment area of swales following Level 2 or 3 detention facilities is required because of the differences in vegetation established in a constant flow environment. Although flows following Level 2 or 3 detention facilities are small, and swales are likewise much smaller than those sized for upstream flows, they are much more protracted. These protracted flows result in more stream -like conditions than are typical for other wet biofilter situations. Since vegetation growing in streams is often less dense, this increase in treatment area is needed to ensure that equivalent pollutant removal is achieved in extended flow situations. 6.3.2.2 DESIGN CRITERIA Swale Geometry Same as specified for basic biofiltration s,,sales (see Section 6.3.1.2, p. 6-43) except for the following modifications:„P+0 1. Criterion 1: The maximum bottom width may be increase to 25 feet, but a length -to -width ratio of 5:1 must be provided. No longitudinal dividing berm is needed. Note: The minimum Swale length is still 100 feet. 2. Criterion 2: If longitudinal slopes are greater than 2 percent, the wet swale must be stepped so that the slope within the stepped sections averages 2 percent. Steps may be made of retaining walls, log check dams, or short riprap sections. No underdrain or low -flow drain is required. 3. Criterion 3: Curved swales are allowed and the application of criteria for maintenance access road curves are not required. 2009 Surface Water Design Manual 1/9/2009 6-55 SECTION 6.3 BIOFILTRATION FACILITY DESIGNS High -Flow Bypass A high -flow bypass is required for flows greater than the water quality design flow to protect wetland vegetation from damage.16 The bypass may be an open channel parallel to the wet biofiltration swale. Water Depth and Base Flow Same as for basic biofiltration swales (see page 6-44), except the design water depth shall be 4 inches or less for all wetland vegetation selections, and no underdrains or low -flow drains are required. Flow Velocity, Energy Dissipation, and Flow Spreading Same a$ for basic biofiltration swales (see page 644), except no flow spreader is needed. Access Same as for basic biofiltration swales (see page 6-46) except access is only required to the inflow and the outflow of the swale; access along the length of the swale is not required. Also, wheel strips may not be used for access in the swale. Intent: An access road is not required along the length of a wet swale because of infrequent access needs. Frequent mowing or harvesting is not desirable. In addition, wetland plants are fairly resilient to sediment -induced changes in water depth, so the need for access should be infrequent. Soil Amendment Same as for basic biofiltration swales (see page 6-46). Planting Requirements Same as for basic biofiltration swales (see page 6-47) except for the following modifications: 1. A list of acceptable plants with recommended spacing is given in Table 6.3.2.A (p. 6-57). In general, it is best to plant several species to increase the likelihood that at least some of the selected species will find growing conditions favorable. 2. A wetland seed mix may be applied by hydroseeding, but if coverage is poor, planting of rootstock or nursery stock is required. Poor coverage is considered to be more than 30 percent bare area through the upper 2/3 of the swale after four weeks. Recommended Design Features Same as for basic biofiltration swales (see page 6-49). Construction Considerations Same as for basic biofiltration swales (see page 6-50). Maintenance Considerations Same as for basic biofiltration swales (see page 6-50), except mowing of wetland vegetation is not required. However, harvesting of very dense vegetation may be desirable in the fall after plant die -back to prevent the sloughing of excess organic material into receiving waters. Many native Juncus species remain green throughout the winter; therefore, fall harvesting of Juncus species is not recommended. 16 Unlike grass, wetland vegetation will not quickly regain an upright attitude after being laid down by high flows. New growth, usually from the base of the plant, often taking several weeks, is required to regain its upright form. 1/9/2009 2009 Surface Water Design Manual 6-56 0 FINISH SURFACE SPRINKLER FLUSH OROF PUNT WITH FINISH GRADE o RB PVG TEE OR ELBOW ' ✓,/"� � 4 ' ? � � PVC, LATERAL LINE a W DEGREE PVG ELBOW SECTION 32, TWP 24 N, R 5 E, W.M.

Based on that meeting, I've tried to answer your questions. I have cc'd Steve Lee from the City to try to clarify or correct anything I note here. 1. What are the areas they want to install plant material vs hydro -seeding? o The planter strip between the road and the sidewalk will be sod with trees. There are overhead powerlines here so the trees can't get too tall. We had discussed using Lynden types of trees. The first tree to lay out should be approximately 20' south of "CB-3" Gto allow access to the manhole) and then the trees were going to be centered off of the placement of that one tree. Trees will then be 40' on ranter and centered within the planter strip. Trees need to be 6' away from the fire hydrant near the driveway entrance to the bioswale. o The bioswale will have plants surrounding it on all four sides. The west side (near the sidewalk) should contain plants that get about 2' high along the top of the bioswale. As the bioswale slopes in, the thought was to have plants that would reach 3'-4' high. Around the other three sides on the top of the bioswale, I believe the city wanted privacy types of shrubs but Steve, correct me if I'm wrong on that. Below is a chart �i of acceptable plants within the bioswale (i.e. on the slopes and bottom floor). The previous landscape architect was not going to plant the floor of the bioswale and noted that the side slope plants would creep toward the bottom over time. Th Ik. o 3' of topsoil is n nder the sod in the gLanter stri They require sandy loam topsoil available from Pacific Topsoils or Cedar . The city s standard specs should state what to use. Let me know if you don't have this. What areas has the City envisioned irrigation, if any? o Irrigation was envisioned for the bioswale plants. They were planning on using temporary irrigation (for 1-2 years). They mentioned burying the system along with the shut off to avoid vandalism during the temporary period. o I didn't look over the specs and details that were given to us by the city but in the meeting, they mentioned using 1800 series Sentinel controller with spray heads. o The controller was to go by the pole on the south end of the job for a power drop. o A double check 1" meter was to be used. o It was intended to have jute matting along the side slopes of the bioswale to help with erosion issues. If irrigation is anticipated, any restrictions for the point of connection for water and power? o This is definitely not my field of expertise so Steve, please let Cal know if I'm missing something. From the meeting we had, there was a question on whether the controller (2-3 amps) needed to be metered. The city was supposed to get back to us on that one. o Steve will have to expand on this issue as well but there was a conversation about where a signal could be received. A lift station across the street can receive a signal. City hall can as well. 4. Is the 'pond' a wet pond or rain garden? o Theoretically, the "pond" is a "wet bioswale". Due to the flat slopes we had to work with, it will have a minimum of 1' of standing water in it at all times. S. From the plans provided, I have questions how run-off enters or is drained from the 'pond'. Please clarify. o Runoff will flow from the street and off -site areas into CB 2 (Station 19+37) where flow is split. The 'water quality" flow will be directed south/southeast through a 12" pipe into the bioswale. The remaining flow continues south/southwest through a 24" pipe toward May Creek. The "water quality" flow will go through the bioswale and will leave the bioswale through a 12" pipe at the south end of the bioswale where it then joins with the 24" pipe at CB 1 (Station 17+22). Once the flows join, they continue south and discharge into to May Creek. There needs to be a clear zone (i.e. no plants) around the 12" diameter inlet and outlet pipes in the bioswale. In other notes, the City wanted a one-year maintenance included in the specs that included plant establishment, irrigation, and health of survivability. In terms of a schedule, it would be nice to have this within 3-4 weeks. The city will need time to review the plans. It is likely that this job is going to a shorelines hearing in January. They hope to bid the project shortly thereafter however we just delivered the city 90% plans so that we can have this designed and ready to go prior to the hearing in January. Please let me know if you have additional questions or concerns. If you feel we should meet with the city to discuss further issues, please let me know. Thank you.

I did get the a -mails regarding plant material and the boiler plate for the specs and .pdf files showing the location and general scope of the project. Wanting to not be lagging behind, I want to be up to speed with the project. While we have a draft of your proposed A/E agreement sent earlier this year, you mentioned that another agreement would be sent. Has a schedule for the project been set?
