FM.DNS 1 June 6, 1989 R9 Cameron j 'O"- ,City Engineer Tukwila Public Works Department RE: EPIC -14 -89 (Nelson Place Drainage Project) Dear Ron, It is my understanding that the proposed drainage project design will be modified as follows: 1. A piped area -wide system will collect storm water runoff and carry it to the P -1 Storm Water Facility. All open ditch segments will be built as enclosed pipe lines; 2. This runoff will be "cleansed" by either (a) bio- filtration swales at each site or (b) at a community biofiltration facility; and 3. Storm runoff detenti p will continue to be provided at individual sites6tv.arki' 0-- c-ok%•14-vr,,i7 S� Please contact me immediately at 433 -1858 if I am mistaken in the above project description. I will continue SEPA processing of this project and anticipate a determination by June 9, 1989.

Give brief, complete description of your proposal, including the pro- posed use and the size of the project and site. There are several questions later in this checklist that ask you to describe certain aspects of the proposal. You do not need to repeat those answers on this page. Section E requires a complete description of the objectives and alternatives of your proposal and should not be summarized here. The proposed project (Figure 2) is a drainage system which allows the City of Tukwila to adequately control and manage stormwater runoff in the Nelson Place /Longacres Drive drainage basin. The project consists of a gravity pipeline element which drains to a common discharge point at the northeast corner of the basin. From this point a new pipeline along S.W. 16th Street will outfall to Springbrook Creek at the location of the proposed P -1 channel. A common detention and biofiltration facility may also be developed. On -site detention and filtration may also be required, depending upon adequacy of the common facility. In addition, storm water will continue to exit the site via the Longacres drainage system at a rate not to exceed the current flowrate. Channels (as currently envisioned) will run parallel to the west side of both the Union Pacific (UP) and Burlington Northern (BN) railroad tracks and into Subbasin 2, as shown on Figure 2. A third channel was originally designed to run parallel to South 158th Street from Nelson Place east and intersect storm drains at Nelson Place and Tukwila Downs Boulevard as well as the UP channel. (This channel may need to be reconfigured on adjacent properties, maintaining the benefits of open swale conveyance, and providing sufficient pressure head to facilitate drainage to the P -1 Channel). This system is equivalent to that developed in the Prelimi- nary Design Report prepared by the City. 12. Location of the proposal. Give sufficient information for a person to understand the precise location of the proposed project, including a street address, if any, and section, township, and range, if known. If a proposal would occur over a range of area, provide the range or boundaries of the site(s). Provide a legal description, site plan, vicinity map, and topographic map, if reasonably available. While you should submit any plans required by the agency, you are not required to ' duplicate maps or detailed plans submitted with any permit applications related to this checklist. The project location is the Nelson Place /Longacres Drive drainage basin within the City of Tukwila. See attached vicinity map (Figure 1). 13.

SUPPLEMENTAL SHEET FOR ALL PROJECT AND NON PROJECT PROPOSALS The objectives and the alternative means of reaching the objectives for a proposal will be helpful in reviewing the aforegoing items of the Environmental Checklist. This information provides a general overall perspective of the proposed action in the context of the environmental infor- mation provided and the submitted plans, documents, suppor- tive information, studies, etc. 1. What are the objective(s) of the proposal? The object - tives of this project are to develop an effective drain- age system for the Nelson Place /Longacres Drive Basin which satisfies the necessary criteria and constraints as outlined in King County Department of Public Works' Storm Drainage Control Requirements and Guidelines, May 1979. 2. What are the alternative means of accomplishing these objectives? The City of Tukwila's Nelson Place /Long- acres Way Storm Drainage System Preliminary Design Report (June 1988) examined several drainage configura- tion alternatives. These alternatives cover options (1) where the entire system consists of gravity flow buried pipeline and (2) where the system consists of a combination of pipelines and channels. 3. Please compare the alternative means and indicate the preferred course of action: A comparative analysis of alternatives resulted in choosing a pipeline system plan for the following reasons: 1. The single- network system limits the number of rail- road crossings to one. 2. A ditch component required a minimum 30 -foot width and was therefore not practical in some cases. • • Evaluation for Agency Use Only 4. Does the proposal conflict with policies of the Tukwila Comprehensive Land Use Policy Plan? If so, what poli- cies of the Plan? This prculosal is consistent with and a facilitation of the Tukwila Comprehensive Land Use Policy Plan. Proposed measures to avoid or reduce the conflict(s) are: Nct applicable. -23- t :,.

Give brief, complete description of your proposal, including the pro- posed use and the size of the project and site. There are several questions later in this checklist that ask you to describe certain aspects of the proposal. You do not need to repeat those answers on this page. Section E requires a complete description of the objectives and alternatives of your proposal and should not be summarized here. The proposed project (Figure 2) is a drainage system which allows the City of Tukwila to adequately control and manage stormwater runoff in the Nelson Place /Longacres Drive drainage basin. The project consists of a gravity pipeline element which drains to a common discharge point at the northeast corner of the basin. From this point a new pipeline along S.W. 16th Street will outfall to Springbrook Creek at the location of the proposed P -1 channel. A common detention and biofiltration facility may also be developed. On -site detention and filtration may also be required, depending upon adequacy of the common facility. In addition, storm water will continue to exit the site via the Longacres drainage system at a rate not to exceed the current flowrate. Channels (as currently envisioned) will run parallel to the west side of both the Union Pacific (UP) and Burlington Northern (BN) railroad tracks and into Subbasin 2, as shown on Figure 2. A third channel was originally designed to run parallel to South 158th Street from Nelson Place east and intersect storm drains at Nelson Place and Tukwila Downs Boulevard as well as the UP channel. (This channel may need to be reconfigured on adjacent properties, maintaining the benefits of open swale conveyance, and providing sufficient pressure head to facilitate drainage to the P -1 Channel). This system is equivalent to that developed in the Prelimi- nary Design Report prepared by the City. 12. Location of the proposal. Give sufficient information for a person to understand the precise location of the proposed project, including a street address, if any, and section, township, and range, if known. If a proposal would occur over a range of area, provide the range or boundaries of the site(s). Provide a legal description, site plan, vicinity map, and topographic map, if reasonably available. While you should submit any plans required by the agency, you are not required to duplicate maps or detailed plans submitted with any permit applications related to this checklist. The project location is the Nelson Place /Longacres Drive drainage basin within the City of Tukwila. See attached vicinity map (Figure 1). 13.

SUPPLEMENTAL SHEET FOR ALL PROJECT AND NON PROJECT PROPOSALS The objectives and the alternative means of reaching the objectives for a proposal will be helpful in reviewing the aforegoing items of the Environmental Checklist. This information provides a general overall perspective of the proposed action in the context of the environmental infor- mation provided and the submitted plans, documents, suppor- tive information, studies, etc. 1. What are the objective(s) of the proposal? The object - tives of this project are to develop an effective drain- age system for the Nelson Place /Longacres Drive Basin which satisfies the necessary criteria and constraints as outlined in King County Department of Public Works' Storm Drainage Control Requirements and Guidelines, May 1979. 2. What are the alternative means of accomplishing these objectives? The City of Tukwila's Nelson Place /Long- acres Way Storm Drainage System Preliminary Design Report (June 1988) examined several drainage configura- tion alternatives. These alternatives cover options (1) where the entire system consists of gravity flow buried pipeline and (2) where the system consists of a combination of pipelines and channels, 3. Please compare the alternative means and indicate the preferred course of action: A comparative analysis of alternatives resulted in choosing a pipeline system plan for the following reasons: 1. The single- network system limits the number of rail- road crossings to one. 2. A ditch nomponent required a minimum 30 -foot width and was therefore not practical in some cases. • • Evaluation for Agency Use Only 4. Does the proposal conflict with policies of the Tukwila Comprehensive Land Use Policy Plan? If so, what poli- cies of the Plan? This proposal is consistent with and a facilitation of the Tukwila Comprehensive Land Use Policy Plan. Proposed measures to avoid or reduce the conflict(s) are: Nct applicable. -23- t 7.i !.. 1 a 7 '" ,:. 1 , ;, L., .b ... v. . • ••• V' Z •• •• * . : ." *.: g:'..--..r.grai. ..., i 1 ,.. • !
