SEPA ENVIRONMENTAL CHECKLIST. Purpose of checklist:

Transcription

1 SEPA ENVIRONMENTAL CHECKLIST Purpose of checklist: Governmental agencies use this checklist to help determine whether the environmental impacts of your proposal are significant. This information is also helpful to determine if available avoidance, minimization or compensatory mitigation measures will address the probable significant impacts or if an environmental impact statement will be prepared to further analyze the proposal. Instructions for applicants: This environmental checklist asks you to describe some basic information about your proposal. Please answer each question accurately and carefully, to the best of your knowledge. You may need to consult with an agency specialist or private consultant for some questions. You may use not applicable or "does not apply" only when you can explain why it does not apply and not when the answer is unknown. You may also attach or incorporate by reference additional studies reports. Complete and accurate answers to these questions often avoid delays with the SEPA process as well as later in the decisionmaking process. The checklist questions apply to all parts of your proposal, even if you plan to do them over a period of time or on different parcels of land. Attach any additional information that will help describe your proposal or its environmental effects. The agency to which you submit this checklist may ask you to explain your answers or provide additional information reasonably related to determining if there may be significant adverse impact. Instructions for Lead Agencies: Please adjust the format of this template as needed. Additional information may be necessary to evaluate the existing environment, all interrelated aspects of the proposal and an analysis of adverse impacts. The checklist is considered the first but not necessarily the only source of information needed to make an adequate threshold determination. Once a threshold determination is made, the lead agency is responsible for the completeness and accuracy of the checklist and other supporting documents. Use of checklist for nonproject proposals: For nonproject proposals (such as ordinances, regulations, plans and programs), complete the applicable parts of sections A and B plus the SUPPLEMENTAL SHEET FOR NONPROJECT ACTIONS (part D). Please completely answer all questions that apply and note that the words "project," "applicant," and "property or site" should be read as "proposal," "proponent," and "affected geographic area," respectively. The lead agency may exclude (for nonprojects) questions in Part B - Environmental Elements that do not contribute meaningfully to the analysis of the proposal.

5 B. Environmental Elements 1. Earth a. General description of the site: (circle one): Flat, rolling, hilly, steep slopes, mountainous, other The site is generally flat with minor slopes along the perimeter. b. What is the steepest slope on the site (approximate percent slope)? 2-5% c. What general types of soils are found on the site (for example, clay, sand, gravel, peat, muck)? If you know the classification of agricultural soils, specify them and note any agricultural land of long-term commercial significance and whether the proposal results in removing any of these soils. According to a NRCS Web Soil Survey, most of the site is shown as Spanaway gravelly sandy loam. Much of the northern part of the site shows Alderwood gravelly sandy loam or Everett very gravelly sandy loam. A small area of the site, directly south of the off-site stormwater detention pond is listed as Dupont muck. d. Are there surface indications or history of unstable soils in the immediate vicinity? If so, describe. The geotechnical study did not identify unstable soils. e. Describe the purpose, type, total area, and approximate quantities and total affected area of any filling, excavation, and grading proposed. Indicate source of fill. The site is relatively flat and generally slopes from the northwest corner of the site to the southwest corner. The proposed location of the building will be filled slightly to raise the proposed finished floor elevation above the existing grades. Proposed grades surrounding the building will be approximately 2-5%. During subsurface investigation of the site, low quality fill was encountered. It is possible to use this fill under fields and landscaping areas, but it will not be suitable as structural fill. This fill is estimated at 17,000 cubic yards. This fill will likely be capped with cement treated base and left in place to avoid the cost of importing or exporting additional soil. It is anticipated that there will be a net fill of 6,000 cubic yards for the entire project. This number is based solely on a comparison of the existing grade and finished grade elevations. It does not take into account existing or proposed surfacing depths, foundations, utility excavations, etc. f. Could erosion occur as a result of clearing, construction, or use? If so, generally describe. Erosion may occur during construction. A temporary erosion and sediment control plan will be prepared following the requirements of the City s Stormwater Manual. Measures may be required to prevent sediment-laden runoff from exiting the project site during construction. SEPA Environmental checklist (WAC ) Mann Middle School March 2018 Page 5 of 17

6 g. About what percent of the site will be covered with impervious surfaces after project construction (for example, asphalt or buildings)? Upon completion approximately 57 percent of the site will be covered with impervious surfaces. h. Proposed measures to reduce or control erosion, or other impacts to the earth, if any: All construction stormwater will need to be maintained on the site per Washington State Department of Ecology standards. Erosion control measures are anticipated to include a rock construction entrance, filter fabric fence, storm inlet sediment projection, and if required a temporary sediment pond. Cover measures are also anticipated and include stockpile protection as well as temporary seeding and mulching. All construction equipment will be required to enter through a gravel construction exit. Other BMP s such as catch basin inlet protection will need to be placed on all existing stormwater catch basins and on proposed catch basins as they are constructed. Daily inspections of the site and maintenance of track off onto surrounding roads will be required throughout construction. 2. Air a. What types of emissions to the air would result from the proposal during construction, operation, and maintenance when the project is completed? If any, generally describe and give approximate quantities if known. Airborne particulates (dust) along with vehicular exhaust from construction equipment are the most likely short-term sources of emissions during construction activity. b. Are there any off-site sources of emissions or odor that may affect your proposal? If so, generally describe. Aside from vehicular exhaust originating with traffic on the adjacent rights-of-way, no offsite sources of emissions and/or odors have been identified. c. Proposed measures to reduce or control emissions or other impacts to air, if any: Airborne particulates will be minimized through surface watering during the construction phase of the project. Construction emissions will be further reduced through emission equipment in an effort to fully comply with Washington State emission standards. 3. Water a. Surface Water: 1) Is there any surface water body on or in the immediate vicinity of the site (including year-round and seasonal streams, saltwater, lakes, ponds, wetlands)? If yes, describe type and provide names. If appropriate, state what stream or river it flows into. Carp Lake is located directly to the southeast and a stormwater detention pond is located directly north of the site. Carp Lake is a man-made waterbody, not classified as a wetland or lake.

Yes, the construction of the football/soccer field will occur within less than 100 feet of Carp Lake. 3) Estimate the amount of fill and dredge material that would be placed in or removed from surface water or wetlands and indicate the area of the site that would be affected. Indicate the source of fill material. Not applicable. No fill or dredging material would be placed in or removed from adjacent surface waters. 4) Will the proposal require surface water withdrawals or diversions? Give general description, purpose, and approximate quantities if known. No 5) Does the proposal lie within a 100-year floodplain? If so, note location on the site plan. No 6) Does the proposal involve any discharges of waste materials to surface waters? If so, describe the type of waste and anticipated volume of discharge. No b. Ground Water: 1) Will groundwater be withdrawn from a well for drinking water or other purposes? If so, give a general description of the well, proposed uses and approximate quantities withdrawn from the well. Will water be discharged to groundwater? Give general description, purpose, and approximate quantities if known. No, the school uses municipal water. 2) Describe waste material that will be discharged into the ground from septic tanks or other sources, if any (for example: Domestic sewage; industrial, containing the following chemicals... ; agricultural; etc.). Describe the general size of the system, the number of such systems, the number of houses to be served (if applicable), or the number of animals or humans the system(s) are expected to serve. Not applicable. c. Water runoff (including stormwater): 1) Describe the source of runoff (including storm water) and method of collection and disposal, if any (include quantities, if known). Where will this water flow? Will this water flow into other waters? If so, describe. SEPA Environmental checklist (WAC ) Mann Middle School March 2018 Page 7 of 17

8 Stormwater runoff will meet the requirements of the Department of Ecology s 2014 Stormwater Management Manual for Western Washington as adopted by the City of Lakewood. All stormwater that runs off of pollution generating surfaces (pavement with vehicle traffic) will be treated for stormwater quality. Treatment will be provided by shallow bioretention facilities. The treatment facilities will be equipped with a type 1 catch basin with a beehive grate to handle runoff flows in excess of the required treatment flows. 2) Could waste materials enter ground or surface waters? If so, generally describe. The project will utilize infiltration trenches sized to store and infiltrate 100 percent of the runoff from the tributary basin, up to and including the 100-year, 24-hour design storm event. 3) Does the proposal alter or otherwise affect drainage patterns in the vicinity of the site? If so, describe. No. d. Proposed measures to reduce or control surface, ground, and runoff water, and drainage pattern impacts, if any: Onsite infiltration will be utilized to infiltrate 100% of the stormwater from the project site. As required by the stormwater manual and the City treatment of this stormwater will be provided prior to infiltrating. 4. Plants a.

15 14. Transportation a. Identify public streets and highways serving the site or affected geographic area and describe proposed access to the existing street system. Show on site plans, if any. Access is proposed via two existing driveways. One driveway is located along Holden Road SW and would accommodate school drop-off/pick-up and special education buses and one driveway along 116 th St SW, which would accommodate bus drop-off/pick-up. Access to the driveways is via either 112 th St SW to the north or Military Road SW to the west. b. Is the site or affected geographic area currently served by public transit? If so, generally describe. If not, what is the approximate distance to the nearest transit stop? Pierce Transit Route 214 has 2 stops within a quarter mile. c. How many additional parking spaces would the completed project or non-project proposal have? How many would the project or proposal eliminate? Mann Middle School currently has 86 striped parking spaces plus an additional parking area without striping. The completed project will have approximately 189 vehicle parking spaces and 14 full and 4 small size bus parking spaces. The Transpo Group s Transportation Impact Analysis (TIA) describes that a study of parking demand was completed for both schools and determined that the combined demand was for approximately 90 spaces. With the proposed capacity increase it is anticipated that the peak parking demand will be 98 spaces. The study concludes the proposed parking supply will accommodate the peak demand. d. Will the proposal require any new or improvements to existing roads, streets, pedestrian, bicycle or state transportation facilities, not including driveways? If so, generally describe (indicate whether public or private). Frontage improvements are anticipated to be required along the north side of 116th ST SW between the 116 th ST SW/Holden Rd. SW intersection and the bus loop access. It is assumed these frontage improvements will be limited to concrete curb and gutter with adjacent sidewalk. A new pedestrian connection will be provided through the site to the east. e. Will the project or proposal use (or occur in the immediate vicinity of) water, rail, or air transportation? If so, generally describe. No. f. How many vehicular trips per day would be generated by the completed project or proposal? If known, indicate when peak volumes would occur and what percentage of the volume would be trucks (such as commercial and nonpassenger vehicles). What data or transportation models were used to make these estimates? SEPA Environmental checklist (WAC ) Mann Middle School March 2018 Page 15 of 17

16 As shown in Table 7 of the TIA, the completed project is anticipated to generate approximately 211 net new weekday AM peak hour trips and 158 net new weekday PM school peak hour trips. The TIA anticipates 776 average vehicular trips per day. The trip generation is based on the following assumptions described in the traffic study: With completion of the proposed project enrollment is anticipated to be approximately 1,000 students. It is anticipated that not all Woodbrook Middle School students would be relocated to the Mann Middle School site. Additionally, because the schools have different trip generation rates a split in the anticipated enrollment was assumed similar to the current split between Mann and Woodbrook Middle Schools. Given the uncertainty of how school boundaries may change over time and the possibility that Woodbrook School students may no longer utilize bus service, it was assumed that some Woodbrook Middle School students would follow the higher trip generation profile of Mann Middle School. The future trip generation calculation is based on approximately 60 percent of the future student population following the Mann Middle School trip generation profile and 40 percent following the Woodbrook Middle School trip generation profile. g. Will the proposal interfere with, affect or be affected by the movement of agricultural and forest products on roads or streets in the area? If so, generally describe. No. h. Proposed measures to reduce or control transportation impacts, if any: The TIA describes that on-site traffic queuing and parking demands will be met. All offsite study intersections are anticipated to operate at LOS C or better under future withproject conditions with the exception of Holden Road SW/Site Access intersection, which is anticipated to operate at LOS D. Signal warrants were reviewed at the Holden Road SW/Military SW intersection, 15. Public Services a. Would the project result in an increased need for public services (for example: fire protection, police protection, public transit, health care, schools, other)? If so, generally describe. No, the use will remain a school. b. Proposed measures to reduce or control direct impacts on public services, if any. None. 16. Utilities a. Circle utilities currently available at the site: electricity, natural gas, water, refuse service, telephone, sanitary sewer, septic system, other SEPA Environmental checklist (WAC ) Mann Middle School March 2018 Page 16 of 17
