PROJECT DESCRIPTION A proposed 11-lot residential subdivision of a vacant and undeveloped 4.73-acre site; King County parcel number 302104-9041. MAJOR ISSUES Outlined below is a summary of the major issues of your project based on the plans and information submitted for preapplication review. These issues can change due to modifications and revisions in the plans. The major issues section is only provided as a means to highlight critical requirements or issues. Please be sure to read the comments made by all departments in the following sections of this letter. • Planning Division None Mr. Geoff Sherwin Page 2 of 13 August 7, 2020 20-102591-00-PC Doc ID:80614 • Public Works Development Services Division 1. A Surface and Stormwater Utility System Development Charge is required. System development charges (SDCs) are one-time fees that will be paid at the time of development and are intended to recover a share of the cost of system capacity needed to serve growth. 2. Flow Control BMP requirements (Core Requirement #9) shall be implemented per Section 1.2.9.3.2 of the King County Surface Water Design Manual (KCSWDM) for plat infrastructure improvements because the proposed project is a subdivision project that is within the Urban Growth Area and is on a site/parcel less than five acres in size. 3. The city may consider the feasibility of bioretention, but this is not a preferable BMP option for plat infrastructure improvements within the right-of-way due to accessibility and maintenance concerns. Nonetheless, a soils report is required by a licensed geotechnical engineer to prove the suitability of this BMP and its reasonable use in relation to applicable city and county standards and requirements. There are additional requirements for large bioretention facilities that receive runoff from impervious surfaces totaling 10,000 square feet or more; or new pervious surfaces totaling ¾ acre or more; or a combination of impervious and pervious surfaces that results in a 0.15 cfs increase. • Public Works Traffic Division 1. Transportation Concurrency Management (FWRC 19.90) – A transportation concurrency permit with the application fee of $5,086 (11 - 50 trips) is required for the proposed project. 2. Traffic Impact Fees (FWRC 19.91) – Traffic impact fees are required for single-family residential dwelling units and will be assessed at the building permit stage. The estimated total traffic impact fee is $46,800. 3. Frontage Improvements (FWRC 19.135.040) – Construct street frontage improvements and dedicate right-of-way along the property frontage on SW 6th Avenue and SW 366th Street. 4. Access Management (FWRC 19.135.260) – The development shall meet access management standards. The project is neither a short subdivision nor a cluster plat; and therefore, the project does not qualify for use of shared access roads as proposed (FWRC 19.135.250). 5. Block Perimeter (FWRC 18.55.010 & FWRC 19.135.251) – The development shall meet block perimeter requirements of 1,320 feet for non-motorized access, and 2,640 feet for streets. This requirement may be modified by the Public Works Director if connections cannot be made for reasons outlined in the FWRC. DEPARTMENT COMMENTS Outlined below are the comments made by the representatives of each department present at the preapplication conference. Each section should be read thoroughly. If you have questions, please contact the representative listed for that section. COMMUNITY DEVELOPMENT – PLANNING DIVISION Jim Harris, jim.harris@cityoffederalway.com Mr. Geoff Sherwin Page 3 of 13 August 7, 2020 20-102591-00-PC Doc ID:80614 1. Zoning Designation and Density – The site is zoned RS-15.0 (Single-Family Medium-Density Residential, one unit/15,000 square feet.). Lots in the RS 15.0 zone must be a minimum lot size of 15,000 square feet. Per FWRC 19.05.120, lot area means the minimum lot area per dwelling unit based on the underlying zone. For single-family lots, the area of a vehicular access easement, private tract, flagpole, or access panhandle shall not be credited in calculation of the minimum lot area. 2. Review Process – A subdivision of ten or more lots and/or tracts requires review and public hearing on the preliminary plat application by the city’s Hearing Examiner. In summary, following application submittal, the city will review the application for completeness and technical comments. The first procedural decision point is the State Environmental Policy Act (SEPA) review and determination. Following conclusion of the SEPA review, city staff will present the staff report and recommendation on the preliminary plat to the Hearing Examiner, who then makes the final decision on the preliminary plat application. The Hearing Examiner’s written decision on the preliminary plat is based on the applicant satisfying criteria pursuant to FWRC 18.35.170(3). The decision of the Hearing Examiner may be appealed pursuant to FWRC 18.35.210. After the final decision on the preliminary plat, engineering plans must be submitted and reviewed by the city’s Public Works Department. Following review and approval of engineering plans, construction of plat infrastructure may begin. Substantial completion of plat improvements is required prior to final plat review and decision by the City Council as described below. 3. State Environmental Policy Act (SEPA) – The proposed subdivision is not categorically exempt from environmental review pursuant to Washington Administrative Code (WAC) 197-11-800, and is subject to a threshold determination. A completed environmental checklist must be submitted with the Master Land Use application. A thoroughly completed checklist that gives comprehensive answers to each item will expedite the review process. The public, government agencies, and tribes will be invited to comment on the checklist during a 14-day comment period. An environmental threshold determination made by the director must be rendered prior to public hearing on the preliminary plat application. 4. Application / Review Fees – Contact staff at the Permit Center at City Hall (253-835-2607 or permetcenter@cityoffederalway.com) to inquire about application fees in place at the time of application submittal. Also, any third-party reviews by city consultants for review and assistance with geologically hazardous and wetland/stream consultants must be pre-funded and paid by the applicant. 5. Environmentally Critical Areas – The project is in proximity to erosion hazard areas and wetland and fish and wildlife critical area indicators. The application must include a report confirming the presence or absence of regulated critical areas on site. If regulated critical areas are present on site, appropriate critical area studies standards of FWRC 19.145.080, and necessary permitting applications related to each critical area feature, are applicable to the preliminary plat. Any third-party reviews by city consultants for review and assistance with geologically hazardous and wetland/stream consultants must be pre-funded and paid by the applicant. 6. Public Notice – The preliminary plat and SEPA review require a notice of application. Pursuant to recent policy change, city staff will prepare the 300-foot mailing. The applicant will be required to pay for and post city supplied large notice boards at the appropriate times. 7. Design Criteria and Improvements – Subdivisions are subject to the subdivision design and improvements criteria set forth in FWRC Chapters 18.55 and 18.60, respectively. It is the responsibility of the applicant to identify how the proposed subdivision meets applicable design and improvements criteria and is therefore, entitled to the land division. Mr. Geoff Sherwin Page 4 of 13 August 7, 2020 20-102591-00-PC Doc ID:80614 8. Miscellaneous Residential Regulations – a) Maximum height of structures is 30 feet above average building elevation. b) Setbacks for structures are minimum 20-foot front yard and 5-foot side and rear. c) Maximum lot coverage is 50 percent. d) Required parking spaces are a minimum of two per dwelling unit. e) Driveway and/or parking pad may not be closer than five feet to any side property line. 9. Open Space – All residential subdivisions are required to provide open space in the amount of 15 percent of the gross land area of the subdivision site per FWRC 18.55.060(2). A minimum of 10 percent of the open space is required to be usable open space, i.e. appropriate for active recreation areas. Additionally, any onsite open space must be set aside in a tract and owned in common undivided interest by all property owners within the subdivision. All or some of the open space requirement may be satisfied by a fee-in-lieu payment at the discretion of the city’s Parks Director, after consideration of the city’s overall park plan, quality, location, and service area of the open space that would otherwise be provided with the project. The fee in lieu of open space is calculated on 15 percent of the most recent assessed land value of the property. If the fee-in-lieu option is chosen, a written request to Parks Director John Hutton is required. A copy of this request is a required component of the preliminary plat application. Usable open space design size and location options, along with provisions for access, improvements, ownership, and maintenance, will be reviewed in conjunction the with review of the preliminary plat. Critical areas and buffers, conservation tracts, slopes, storm pond tracts, etc. do not qualify as usable open space. Typically, a narrow (three to five-foot-wide) landscape buffer strip is required between streets and above ground stormwater facilities, and may be counted toward the buffer open space. Please consult FWRC 18.55.060 for specific open space requirements that apply to the proposal. 10. Forest Practices – A Forest Practices Class IV-General Application is required if more than 5,000 board feet of merchantable timber will be harvested from the property in conjunction with the development activity. The city will review the proposed Class IV-General Forest Practices in conjunction with SEPA review, and review of associated development permits or approvals. 11. Tree Retention/Replacement – The city’s tree standards require each development/redevelopment to maintain a tree unit density. The minimum tree density requirements for RS zones are 25 tree units per acre. The required density for the subject property will be determined by multiplying the gross site acreage, minus streets and critical areas, by 25. A tree retention plan detailing how the subject property will meet tree unit density requirements shall be submitted with the preliminary plat application. Items required to be included in the plan are itemized in FWRC 19.120.040(2)(a) through (e). The table below identifies tree unit values for retained and replacement trees. Mr. Geoff Sherwin Page 5 of 13 August 7, 2020 20-102591-00-PC Doc ID:80614 FWRC 19.120.130(2) – Tree Unit Credits Retained Trees Tree Unit Credit Existing Tree 1" to 6" d.b.h. 1.0 Existing Tree > 6" to 12" d.b.h. 1.5 Existing Tree > 12" to 18" d.b.h. 2.0 Existing Tree > 18" to 24" d.b.h. 2.5 Existing Tree > 24" d.b.h. 3.0 Replacement Trees Replacement Tree - Small (Mature canopy area < 450 SF) .50 Replacement Tree - Medium (Mature canopy area 450 to 1,250 SF) 1.0 Replacement Tree - Large (Mature canopy area > 1,250 SF) 1.5 12. Clearing & Grading – With the preliminary plat application, a clearing and grading plan addressing items listed in FWRC 19.120.040(1)(a) through (j) is required. Prior to beginning clearing and grading activities, all critical areas and buffers, and trees/vegetation that are to be preserved within and adjacent to the construction area shall be clearly marked and protected per guidelines prescribed within FWRC 19.120.160. Removal of all trees and vegetation is contrary to the objectives of the FWRC clearing and grading regulations under FWRC Chapter 19.120 Article II and Article III. Pursuant to FWRC 19.120.080 and 19.120.130(1), permitted clearing and grading areas should minimize removal of existing trees and minimize the disturbance or compaction of native soils, except as needed for building purposes. For any clearing beyond that necessary for required infrastructure, provide a written request and justification as part of the preliminary plat application. The FWRC policies encourage retention of existing trees and vegetation in good health, to the maximum extent possible in all developments. Any retaining walls and rockeries can be a maximum of six feet in height and must comply with standards in FWRC 19.120.120. Preliminary designs for retaining walls shall be submitted with the preliminary plat application, and include cross sections and visual depictions of retaining walls. 13. Tacoma Smelter Plume – The subject property is located in the Tacoma Smelter Plume detect area; containing 20.1 ppm to 40.0 ppm arsenic and lead concentration. Please contact Technical Assistance Coordinator Eva Barber, Department of Ecology, at eva.barber@ecy.wa.gov, or 360-407-7094, regarding the Voluntary Soil Clean-Up Program. Additional information on the smelter plume testing and cleanup requirements can be found at: http://www.ecy.wa.gov/programs/tcp/sites_brochure/tacoma_smelter/2011/ts-hp.htm. The city will require soil testing and soil cleanup (if applicable) as a component of the preliminary plat and SEPA applications, review, and site development. The applicant shall provide preliminary soil testing data in compliance with Washington State Department of Ecology guidelines with the preliminary plat application. 14. School Access Analysis – A school access analysis is required to be submitted to the city with the plat application, to assure that safe walking routes to schools or bus stops are provided as required by RCW 58.17. If there are not safe and adequate walking routes available, walking route improvements may be required as part of the plat review process. Contact Tanya Nascimento, Federal Way Public Schools, at 253-945-2071 for information about the school access analysis requirements. Mr. Geoff Sherwin Page 6 of 13 August 7, 2020 20-102591-00-PC Doc ID:80614 15. School Impact Fee – School impact fees are paid at the time of the building permit for each individual house, as discussed in FWRC 19.95. 16. Exploratory Site Reconnaissance Work – Please provide city staff written notice before any site reconnaissance work occurs. If any geotechnical exploration, boring work, or any work in critical areas is to occur, this activity must be approved by city staff prior to this work as identified in FWRC 19.145.120(2). 17. Approval Duration – Per FWRC 18.35.220, preliminary plat approval shall expire five years from the date of hearing examiner approval, unless the applicant requests an extension as provided in FWRC 18.05.090. 18. Final Plat – The final plat fee, in effect at the time of the final plat application, and items identified in FWRC 18.40.020, are required to process the final plat. Substantial completion of the plat infrastructure must occur prior to submittal and processing of the final plat application. The city allows bonding of only minor improvements. The City Council will act on the plat and upon approval, the final plat drawing will be recorded with the King County Recorder’s Office. 19. Recording – Following substantial completion of subdivision improvements and City Council review of the final plat, the plat will be recorded the with the King County Recorder’s Office. The applicant is responsible for the plat recording fees. Prior to recording the plat, all surveying and monumentation must be complete. In addition, all other required improvements must be substantially completed as determined by the departments of Community Development and Public Works. PUBLIC WORKS – DEVELOPMENT SERVICES DIVISION Kerry Murdock, 253-835-2746, kerry.murdock@cityoffederalway.com Land Use Issues – Stormwater 1. Surface water runoff control and water quality treatment will be required per the 2016 King County Surface Water Design Manual (KCSWDM). This project meets the requirements for a Full Drainage Review. At the time of land use site plan preliminary plat submittal, a preliminary Technical Information Report (TIR), addressing the relevance of the project to the nine core and five special requirements of the KCSWDM will be required. A Level 1 downstream analysis shall also be provided in the preliminary TIR. The city has 1″ = 100′, five-foot contour planimetric maps in GIS format that may be used for basin analysis. 2. The project lies within a Conservation Flow Control Area; thus, the applicant must design the flow control facility to meet this performance criteria. In addition to flow control facilities, Best Management Practices (BMP’s) are required as outlined in the KCSWDM. The project also lies within an Enhanced Basic Water Quality Area. Water quality treatment shall be designed to meet the treatment criteria of the Enhanced Basic Water Quality Menu. 3. If infiltration is proposed, soil logs prepared by a licensed geotechnical engineer or septic designer must be provided to verify infiltration suitability. 4. Detention and water quality treatment facilities for subdivisions are required to be above ground (i.e. an open pond), within a separate storm drainage tract, and dedicated to the city for future maintenance. Detention and water quality facilities may be within the same tract. Underground facilities are allowed only with approval from the City of Federal Way Stormwater Management Division. Mr. Geoff Sherwin Page 7 of 13 August 7, 2020 20-102591-00-PC Doc ID:80614 5. Show the proposed location and dimensions of the detention and water quality facilities on the preliminary plans. 6. System Development Charge (SDC). Based on the preliminary proposal and the total increase in square footage of impervious surface area (17,319' 9" +/-); and subdivision/plat improvements (current SDC x # of ESU’s / 1 ESU = 3200 square feet) $981.00/ESU x (17,319' 9"/3200 sq. ft / ESU = 5.4~) = $5,309.63 approximate SDC charge, based on the estimated new impervious surface of 17,319' 9". This is subject to change depending on the final impervious total and access management/project scope changes/requirements. 7. If more than one acre will be disturbed during construction, a National Pollutant Discharge Elimination System (NPDES) construction stormwater permit may be required. Information regarding this permit can be obtained from the Washington State Department of Ecology at 360-407-6048, or http://www.ecy.wa.gov/programs/wq/stormwater/construction/index.html. 8. If work is to be done below the ordinary high-water mark, a Hydraulic Project Approval (HPA) permit may be required. Information regarding this permit can be obtained from the Washington Department of Fish and Wildlife. Right-of-Way Improvements 1. See the Traffic Division comments from Senior Traffic Engineer Jason Kennedy for traffic related items. 2. If dedication of additional right-of-way is required to install street frontage improvements, the dedication shall be conveyed to the city through a statutory warranty deed. The dedicated area must have clear title prior to recording. 3. All stormwater treatment and detention requirements outlined above may apply to any improvements within the public right-of-way. 4. FWRC 11.05.110 requires that overhead utility lines be relocated underground if over 500 feet, or three spans are affected by a project. 5. FWRC 19.135.280 requires that driveways serving residential uses may not be located closer than 25 feet to any street intersection. Lots and intersections within new subdivisions or short plats must be designed to meet this standard. Building/Engineering Permit Issues 1. Engineered plans are required for clearing, grading, road construction, and utility work. Plans must be reviewed and approved by the city. Engineering review fees are $3,096.00 for the first 18 hours of review, and $172.00 per hour for additional review time. A final TIR shall be prepared for the project and submitted with the engineering plans. Both the TIR and the plans will require the signature/seal of a professional engineer registered/licensed in the State of Washington. 2. In addition to engineering approval, projects that will be filling or grading in the area of the future building pads are required to obtain a separate grading permit from the Building Division. Mr. Geoff Sherwin Page 8 of 13 August 7, 2020 20-102591-00-PC Doc ID:80614 3. To assist the applicant’s engineer in preparing the plans and TIR, the Federal Way Public Works Development Standards Manual (including standard detail drawings, standard notes, and engineering checklists) is available on the city’s website at http://www.cityoffederalway.com/index.aspx?nid=171. 4. Bonding is required for all street improvements and temporary erosion and sediment control measures associated with the project. The bond amount shall be 120 percent of the estimated costs of the improvements. An administrative fee deposit will need to accompany the bond to cover any possible legal fees in the event the bond must be called. Upon completion of the installation of the improvements, and final approval of the Public Works Inspector, the bond will be reduced to 30 percent of the original amount and held for a two-year maintenance period. 5. The developer will be responsible for the maintenance of all storm drainage facilities (including the detention and water quality facilities) and street systems during the two-year maintenance period. During that time, the Public Works Inspector will make periodic visits to the site to ensure the developer’s compliance with the maintenance requirements. Upon satisfactory completion of the two-year maintenance period, the remainder of the bond will be released. Maintenance for public roads and subdivision drainage facilities then become the responsibility of the city. Maintenance for private roads and drainage facilities, including short plats, remain the responsibility of the individual property owners. 6. When topographic survey information is shown on the plans, the vertical datum block shall include the phrase “DATUM: N.G.V.D.-29” or “DATUM: K.C.A.S.,” on all sheets where vertical elevations are called out. 7. Drawings submitted for plan review shall be printed on 24″ x 36″ or 22″ x 34″ paper. Site plans shall be drawn at a scale of 1″ = 20′, or larger. Architectural scales are not permitted on engineering plans. 8. Provide cut and fill quantities on the clearing and grading plan. 9. Temporary Erosion and Sediment Control (TESC) measures, per Appendix D of the 2016 KCSWDM, must be shown on the engineering plans. 10. The site plan shall show the location of any existing and proposed utilities in the areas affected by construction. PUBLIC WORKS – TRAFFIC DIVISION Jason Kennedy, 253-835-2744, jason.kennedy@cityoffederalway.com Transportation Concurrency Analysis (FWRC 19.90) 1. Based on the submitted materials for 11 lots, using the Institute of Transportation Engineers (ITE) Trip Generation - 10th Edition, land use code 210 (Single-Family Detached Housing), the proposed project is estimated to generate approximately 13 new weekday PM peak hour trips and 136 daily weekday trips. Alternatively, the applicant may submit a site-specific trip generation study for the proposed development. 2. A concurrency permit is required for this development project. The PW Traffic Division will perform a concurrency analysis to determine if adequate roadway capacity exists during the weekday PM peak period to accommodate the proposed development. Please note that a supplemental transportation Mr. Geoff Sherwin Page 9 of 13 August 7, 2020 20-102591-00-PC Doc ID:80614 analysis and concurrency mitigation may be required if the proposed project creates an impact not anticipated in the six-year Transportation Improvement Plan (TIP). 3. The estimated fee for the concurrency permit application is $5,086 (11 - 50 trips). This fee is an estimate and based on the materials submitted for the preapplication meeting. The concurrency application fee must be paid in full at the time the concurrency permit application is submitted with the land use application. The fee may change based on any changes in the estimated weekday PM peak hour trips as identified in the concurrency application. The applicant has the option of having an independent traffic engineer prepare the concurrency analysis consistent with city procedures; however, the fee remains the same. Transportation Impact Fees (TIF) (FWRC 19.91) 1. Based on the submitted materials for 11 single-family residential lots, the estimate total traffic impact fee is $46,800. The actual fee will be assessed and collected from the applicant when the building permit is issued, using the fee schedule then in effect (FWRC 19.100.070[3][c]). At any time prior to building permit issuance, the applicant may request to defer to final building inspection the payment of a transportation impact fee for a single-family residential dwelling unit (FWRC 19.100.075). If this option is selected, a covenant prepared by the city to enforce payment of the deferred fees will be recorded at the applicant’s expense. Refer to defer payment of impact fee code for process. Street Frontage Improvements (FWRC 19.135) 1. The applicant/owner will be expected to construct street improvements consistent with the planned roadway cross-sections as shown in Map III-4 in Chapter III of the Federal Way Comprehensive Plan (FWCP) and Capital Improvement Program (CIP) shown as Table III-10 (FWRC 19.135.040). Based on the materials submitted, staff conducted a limited analysis to determine the required street improvements. The applicant will be expected to construct improvements on the following streets to the city’s planned roadway cross-sections:  Sixth Avenue SW is classified as a Minor Collector and planned as a Type “T” street, consisting of a 28-foot street, 8-foot ditch, 5-foot sidewalk, 3-foot utility strip, and street lights in 60-foot right-of-way. Assuming a symmetrical cross section, half street improvements are required as measured from the street centerline. If necessary, additional right-of-way may be needed to accommodate a 3-foot utility strip that is now shown in the conceptual drawing as 1.86 feet. Additionally, the existing speed bump on Sixth Avenue SW shall be restored to current condition should any construction have impact on its condition.  SW 366th Street is a planned as a Type “T” street, consisting of a 28-foot street, 8-foot ditch, 5-foot sidewalks, 3-foot utility strip, and street lights in a 60-foot right-of-way. Assuming a symmetrical cross section, half street improvements and a 30-foot right-of-way dedication are required as measured from the street centerline. At a minimum, the improvement shall include a 20-foot minimum paved surface. Alternatively, the applicant may make the required improvement to match the cross-section to the east, which is a Type “S” street consisting of a 36-foot street with curb and gutter, 4-foot planter strip with street trees, 5-foot sidewalks, and street lights in a 60-foot right-of-way. The sidewalk proposed SW 366th Street must be within the right-of-way (FWRC 19.135.200). A modification to this requirement must be requested in writing and is subject to approval of the Public Works Director. 2. Street lighting in the right-of-way is required for frontage improvements (FWRC 19.135.190). Mr. Geoff Sherwin Page 10 of 13 August 7, 2020 20-102591-00-PC Doc ID:80614 3. The applicant may make a written request to the Public Works Director to modify, defer, or waive the required street improvements (FWRC 19.135.070). Information about right-of-way modification requests is available through the Public Works Development Services Division. These modification requests have a nominal review fee currently at $344, plus the recording fee. 4. Tapers and transitions beyond the project frontage may be required as deemed necessary for safety purposes. The taper rate shall be WS2/60, or as directed by the Public Works Director. Access Management (FWRC 19.135) 1. Access management standards are based on roadway safety and capacity requirements. FWRC 19.135.280 provides access standards for streets based on planned roadway cross-sections. Please note that access classifications are per Drawing 3-1A in the Public Works Development Standards. 2. The project does not qualify for use of a shared access road as proposed. The project is neither a short subdivision nor a cluster plat and will require modifications to the proposed shared access roads, or revisions to the lot configurations (FWRC 19.135.250). Design Criteria (FWRC 18.55) 1. All lots shall be accessed by a public street right-of-way (FWRC 18.55.020). 2. Block perimeters shall be no longer than 1,320 feet for non-motorized trips, and 2,640 feet for streets (FWRC 18.55.010 and FWCP Policy TP4.2). Therefore, an additional north/south and east/west connection will be required. Miscellaneous Safety Related Comments 1. The applicant must submit a Vehicle Turning Diagram to the Public Works Traffic Division. This diagram will show how the appropriate design vehicle (such as: bus, garbage truck, and WB-62) can enter, maneuver, and leave the site without encroaching onto opposing traffic lanes or mounting a curb. 2. Driveways serving a single-family dwelling unit abutting two streets should be at least 25 feet from the beginning of the street radius. LAKEHAVEN WATER AND SEWER DISTRICT Brian Asbury, 253-946-5407, basbury@lakehaven.org Water • Lakehaven issued a Water Certificate of Availability for the proposed project/property on May 14, 2020. The certificate is valid for one-year from the date of issuance. • Hydraulic model results indicate that Lakehaven’s standard maximum allowable system liquid velocity of 10 ft/s, at no less than 20 psi, is exceeded at a fire flow rate above 3,400 GPM (for two hours or more). This flow figure depicts the calculated performance of the existing water distribution system under high demand conditions. Fire flow rates greater than available in the existing distribution system may be Mr. Geoff Sherwin Page 11 of 13 August 7, 2020 20-102591-00-PC Doc ID:80614 accommodated through water distribution system improvements. Onsite hydraulic system calculations may need to be determined during design of the onsite water distribution system improvements. Please contact Lakehaven for further detail. • A water service connection application submitted separately to Lakehaven is required for each new service connection to the water distribution system, in accordance with standards defined in Lakehaven’s current “Fees and Charges Resolution.” • Depending on the ultimate layout of the subdivision, reservation of a private water easement will presumably be required across one of, or some of, the new lots, for the benefit of other new lot supply lines (meter-to- building).
