Hansen, P.E., Public Works Director:?~ Public Hearing and First Reading of Ordinance No. 634 Implementation of Low Im act Develo ment Guidelines and Princi les ISSUE: Shall the City Council open the public hearing, receive testimony, close the public hearing, and pass first reading of Ordinance No. 634? RECOMMENDATION: To open the public hearing, receive testimony, close the public hearing and pass first reading of Ordinance No POLICY DECISION: Woodinville Municipal Code (WMC) establishes that zoning code amendments, development regulations/amendments, area-wide zoning map amendments, Comprehensive Plan adoption/amendments, and annexations be reviewed by the Planning Commission at a public hearing and then forwarded to the City Council with a recommendation. BACKGROUND/ANALYSIS: The City operates it's stormwater drainage system under the requirements of National Pollution Discharge Elimination System (NPDES) Phase II Permit issued by the Washington State Department of Ecology for the years One of the permit requirements in Section S5.C.4.f, requires the following of permittees, including the City of Woodinville, that "No later than December 31, 2016, permittees shall review, revise and make effective their local development, related codes, rules, standards or other enforceable documents to incorporate and require LID principals and LID Best Management Practices (BMPs)." LID principals are the means and methods to handle stormwater runoff from developed properties in a way that would mimic mother nature if the site was not developed and left in its original undeveloped state. In late 2015, City staff and our On-Call Civil Engineering Consultant, Otak, Inc., started working on this requirement, identifying potentially necessary Woodinville Municipal Code (WMC) and Transportation Infrastructure Standard revisions. Collectively we have identified over 40 potential revisions that should be considered. Sections 14.06, 14.09, 12.09, 13.04, 20.06, 21.11, 21.22, 21.23, 21.26, 21.40, 21.43, 21.44, 21.51, and of the Woodinville Municipal Code (WMC) were either established, eliminated or modified to include LID Standards. In addition, the City's Transportation Infrastructure Standards and Specifications (TISS) were modified with revisions to the text and Standard Plans. Attached is a summary list of the proposed revisions necessary to implement LID techniques and methods into the City's codes and standards. These numerous code and standard changes, when reviewed as a whole, are the staff's recommended revisions to incorporate LID principles and practices into City development standards. Many of the changes are small, but combined together, will result in a significant change in how stormwater runoff is handled within the City of Woodinville in the future. The Planning Commission held a public hearing on the proposed ordinance on September 21, The Commission recommended adopting the proposed ordinance as presented. The staff has not made changes to the proposed ordinance since. The draft ordinance attached is the same as presented to the Commission. 1

For single-family residential subdivisions and short subdivisions on sites with critical areas or buffers, on-site density credits may be transferred from the critical area to a developable site area. In some cases, the maximum density credits may not be attainable due to other site constraints including, but not limited to, acreage constraints of the developable site area. (a) For sites where up to 50 percent of the site is constrained by critical areas, up to 100 percent of the density that could be achieved on the constrained area portion of the site can be transferred to the developable portion of the property. (b) For sites that are over 50 percent constrained by critical areas, up to 50 percent of the density that could be achieved on the constrained area portion of the site can be transferred to the developable portion of the property. ( 4) Density Transfer. On-site density transfer is subject to the following: (a) The density credit can only be transferred within the development proposal site. The on-site density transfer provided for in this section shall not be applied to allow density from a constrained site to be transferred to an unconstrained parcel, lot, or site when combined with a constrained site by 28 Page 26 of 28

Hansen, P.E., Public Works Direct~ Public Hearing - Ordinance No. 634 Implementation of Low Impact Development Guidelines and Principles ISSUE: Shall the Planning Commission hold a public hearing to receive public testimony regarding the proposed implementation of Low Impact Development (LID) Guidelines and Principles into City Code requirements? STAFF RECOMMENDATION: Hold the public hearing and recommend the City Council adopt Ordinance No. 634, Implementation of Low Impact Development Guidelines and Principles. BACKGROUND/ANALYSIS: The City operates it's stormwater drainage system under the requirements of National Pollution Discharge Elimination System (NPDES) Phase II Permit issued by the Washington State Department of Ecology for the years One of the permit requirements in Section S5.C.4.f, requires the following of permittees, including the City of Woodinville, that "No later than December 31, 2016, permittees shall review, revise and make effective their local development, related codes, rules, standards or other enforceable documents to incorporate and require LID principals and LID Best Management Practices (BMPs)." LID principals are the means and methods to handle stormwater runoff from developed properties in a way that would mimic mother nature if the site was not developed and left in its original undeveloped state. In late 2015, City staff and our On-Call Civil Engineering Consultant, Otak, Inc., started working on this requirement, identifying potentially necessary Woodinville Municipal Code (WMC) and Transportation Infrastructure Standard revisions. Collectively we have identified over 40 potential revisions that should be considered. Sections 14.06, 14.09, 12.09, 13.04, 20.06, 21.11, 21.22, 21.23, 21.26, 21.40, 21.43, 21.44, 21.51, and of the Woodinville Municipal Code (WMC) were either established, eliminated or modified to include LID Standards. In addition, the City's Transportation Infrastructure Standards and Specifications (TISS) were modified with revisions to the text and Standard Plans. Listed below is a summation of all these revisions recommended to implement LID Codes and Standards: 1) TISS Adding necessary definitions. 2) TISS Submit drainage system design per adopted Stormwater Manual. 3) TISS Part Revising allowed utility installation location and undergrounding requirements. 4) TISS Encouraging the use of hammerheads instead of cul-de-sacs for emergency vehicle turnarounds. 5) TISS Adding that permeable pavements are allowed on private property. 6) TISS Restrict placement of utilities under bio-retention swales except as necessary. 7) TISS Limit driveway width and number to single family residential lots. 60

64 Page 61 of 134 Exhibit 1 Page 2 of 3 l 8) TISS New standards for commercial driveways.. 9) TISS 1-5..:... Establish goal for using LID in site design. 10) TISS Allow permeable pavement for private parking lots and establish locations where standard hot mix asphalt can be used. 11) TISS Change references to applicable standard plan numbers. 12) TISS Eliminate outdated City details for ADA ramps and change reference to WSDOT ADA ramps which are. regularly changed to meet Federal law. 13) TISS list of modified current standard plans, added standard plans, and deleted standard plans. 14) Revised Code Section WMC establishing best management practices. 15) Revising WMC City Manager adoption of administrative rules. 16) Adopting sections of King County Code 9.04 as referenced with modifications necessary so it refers to Woodinville and Woodinville Municipal Code - establishing flow control, erosion control, and maintenance of stormwater facilities. 17) Deleting WMC Section and which are outdated Water Quality and Surface Water Runoff policy codes which will be replaced with new code sections as outlined in Item 16 above. 18) WMC Adding the definition of bio-retention. 19) WMC Modifying the definition of hard surface to include permeable pavement. 20) WMC Modifying the definition of impervious surface by eliminating exceptions. 21) WMC Added definitions for landscape coverage, low impact development, and LID best management practices. 22) WMC Added definition for permeable pavement, deleting definition for pervious surfacing materials. 23) WMC Changing lot coverage requirements for residential zoning from maximum impervious surface to providing a minimum of landscaping coverage for individual lots. 24) WMC A- Sarne as Item 23 above for commercial/industrial zones. 25) WMC (2)e, (z)f, (6)h - Changing lot coverage from maximum impervious allowed to minimum landscape coverage as in Item 23 above. 26) WMC Change image from typical landscaping to landscaped areas that can serve as landscaping and bio-retention facilities. 27) WMC Incorporating LID, bio-retention features/swales, into landscape areas. 28) WMC (2) -Allowing landscaped bio-retention areas to serve as screening of blank building walls. 29) WMC ;._ Allow bio-retention landscape areas to be considered "landscaping" along street frontages. 30) WMC Incorporating LID features and plant materials into general landscaping requirements for projects. 31) WMC (4)-Delete definition of Type 4 landscaping for parking lots. 61

65 Page 62 of 134 Exhibit 1 Page.3 of 3 32) WMC Establish new r~quirements for landscaping within and on the perimeter of parking lots and include/allow LID and bio-retention features to serve as this landscaping. 33) WMC 21A3.090(3) -Requires utilities to amend soils to promote tree health and provide appropriate tree spacing when new trees are planted. 34) WMC Establishes requirements for installation of landscaping. 35). WMC Requires adjacent property owners to maintain landscaping in City. rights-of-way in front of their property to the curb or edge of p~vement. 36) WMC (4) - Establishes a maximum number of parking stalls allowed for a development, limiting the amount of impervious/developed surface created. 37) WMC Refers parking lot surfacing requirements to the standards established in the City's TISS. 38) WMC :... Changes maximum impervious surface allowed to minimum landscape coverage for the development within critical areas. 39) WMC Establishes responsibility for maintenance of storm drainage facilities. These numerous code and standard changes, when reviewed as a whole, are the staff's recommended revisions to incorporate LID principles and practices into City development standards. Many of the changes are small, but combined together, will result in a significant change in how stormwater runoff is handled within the City of Woodinville in the future. ALTERNATIVES: 1.

WMC section is hereby amended to read as follows, with new text shown by underline and deletions of text shown by strikethrough; all other provisions of this section shall remain unchanged and in full force: Subdivisions and density calculations within critical areas. ( 1) Intent. The intent of this section is to provide for the preservation of critical areas and their buffers, flexibility in design, and consistent treatment of different types of development proposals. (2) Subdivisions in Critical Areas. The subdivision and short subdivision of land including landslide and erosion hazard areas, frequently flooded areas, wetlands, streams, and fish or wildlife habitat conservation areas shall be subject to the following: (a) Land that is located wholly within a critical area or its buffer may not be divided. (b) Land that is located partially within a critical area or its buffer may be divided; provided, that the developable portion of each new lot and its access is located outside of the critical area or its buffer. Each resulting lot shall meet the minimum lot size and have sufficient buildable area outside of, and will not affect, the critical area or its buffer; and (c) Access roads and utilities serving the proposed subdivision or short subdivision may only be permitted within the critical area and its buffers if the City determines that no other feasible alternative exists and when consistent with this chapter. (3) On-Site Density Credits. For single-family residential subdivisions and short subdivisions on sites with critical areas or buffers, on-site density credits may be transferred from the critical area to a developable site area. In some cases, the maximum density credits may not be attainable due to other site constraints including, but not limited to, acreage constraints of the developable site area. (a) For sites where up to 50 percent of the site is constrained by critical areas, up to 100 percent of the density that could be achieved on the constrained area portion of the site can be transferred to the developable portion of the property. (b) For sites that are over 50 percent constrained by critical areas, up to 50 percent of the density that could be achieved on the constrained area portion of the site can be transferred to the developable portion of the property. ( 4) Density Transfer. On-site density transfer is subject to the following: (a) The density credit can only be transferred within the development proposal site. The on-site density transfer provided for in this section shall not be applied to allow density from a constrained site to 26 87

115 Page 112 of 134 Exhibit 2 Page 27 of 28 be transferred to an unconstrained parcel, lot, or site when combined with a constrained site by subdivision, binding site plan, boundary line adjustment, or other means of land assemblage or arrangement for development. (b) No additional density is allowed over the base density of the underlying zone. ( c) The minimum lot size and other dimensional requirements of the underlying zoning classification may be reduced to accommodate the transfers in densities per the following table: Table (4)(c)- Reduced Dimensional Standards Maximum lmtte:f i0us Minimum Lot Size Maximum Su:Ffaee Zone Building Coverage Minimum Landscaning Lot Width at Street Coverage R-1 31,000 sf 15% ~75% 100 ft/ 75 ft on cul-de-sac R-4 7,200 sf 35% ~50% 60 ft R-6 5,000 sf 50%.'.7(}25% 50 ft R-8 4,600 sf 55%.'.7-20% 30 ft (d) All other applicable dimensional requirements pursuant to WMC shall be met. ( e) The area to which the density is transferred shall not be constrained by another critical area regulation. (f) No portion of the critical area shall be included as part of the minimum lot size. (g) The lot sizes shall not be averaged pursuant to WiviC 2i (h) No panhandle lots are permitted. (5) Except as allowed bywmc , in no event shall a lot be less in size than specified by subsection (4) of this section. Section 45. WMC section is hereby amended to read as follows, with new text shown by underline and deletions of text shown by strikethrough; all other provisions of this section shall remain unchanged and in full force: Storm drainage. ( 1) All lots shall be provided with adequate storm drainage connected to the storm drainage system of the City or other system approved by the City..

140 Exhibit 4 Page 1 of 18 PUBLIC HEARING DRAFT ORDINANCE NO. 634 LOW IMPACT DEVELOPMENT (LID) CODE AMENDMENTS PRESENTATION TO THE CITY COUNCIL OCTOBER 18, 2016

141 Exhibit 4 Page 2 of 18 BACKGROUND City operates it s stormwater drainage system under a National Pollutant Discharge Elimination System (NPDES) Permit issued by the Washington State Department of Ecology. Current permit effective 08/01/13 to 07/31/18. Section S5.C.4.f of the current Permit No later than December 31, 2016, Permittees shall review, revise and make effective their local development-related codes, rules, standards, or other enforceable documents to incorporate and require LID principles and LID BMPs. The intent of the revisions shall be to make LID the preferred and commonly-used approach to site development. The revisions shall be designed to minimize impervious surfaces, native vegetation loss, and stormwater runoff in all types of development situations. Permittees shall conduct a similar review and revision process, and consider the range of issues, outlined in the following document: Integrating LID into Local Codes: A Guidebook for Local Governments (Puget Sound Partnership, 2012).

142 Exhibit 4 Page 3 of 18 WHAT IS LOW IMPACT DEVELOPMENT (LID)? From the Department of Ecology NPDES Permit for Phase 1 Permittees LID Definition: Low-impact development (LID) is a stormwater and land use management strategy that strives to mimic pre-disturbance hydrologic processes of infiltration, filtration, storage, evaporation, and transpiration by emphasizing conservation, use of on-site natural features, site planning, and distributed stormwater management practices that are integrated into a project design. Tom Hansen s Translation for us normal folk: So stormwater/rainfall drains like it did before Western Civilization got here in 1850 and screwed it up!

143 THE GOAL OF LID EMULATES HISTORIC (PRE-1850) RUNOFF PATTERNS Exhibit 4 Page 4 of 18

144 Exhibit 4 Page 5 of different sections of the Transportation Infrastructure Specifications and Standards (TISS), adopted by WMC 12.09, and 14 sections of the Woodinville Municipal Code, are either modified, changed, or replaced to include LID methods, means, and requirements into City Development Standards. Staff will not be presenting exhaustive list with this briefing, information is in the packet and Draft Ordinance, but will present high level overview of the recommended changes to the City s Development Standards.

145 Exhibit 4 Page 6 of 18 Code revisions include adoption of the 2016 King County Surface Water Design Manual. This version includes a new Core Requirement titled Flow Control BMP s (Best Management Practices) This new Core Requirement necessitates: Preservation and use of native vegetated areas to fully disperse runoff Use of pervious surfaces to disperse runoff Roof downspout infiltration Permeable pavements, bio-retention, infiltration systems, Reduction in development footprint Responsibility of applicant/designer to choose means and methods to meet this requirement for their proposed development. Changes in City Code are needed to both require, encourage, and facilitate this revised means of dealing with stormwater runoff.

151 Exhibit 4 Page 12 of 18 ALL OTHER STREET SECTIONS Allow / encourage bio-retention swales / areas where planter strips used to be

152 Exhibit 4 Page 13 of 18 STREET END OPTIONS Hammerhead Preferred / Encouraged Cul-de-sac, Discouraged Allowed if approved by Director

153 Exhibit 4 Page 14 of 18 PERMEABLE PAVEMENT ALLOWED IN Private parking lots/areas Sidewalks/walkways on private property Not allowed on public roadways, sidewalks, areas that City crews are responsible to maintain.

154 Exhibit 4 Page 15 of 18 OTHER SIGNIGICANT REVISIONS Changed lot coverage from Maximum Impervious Surface Allowed to Minimum Landscaping Required. Included bio-retention facilities/swales as landscaped areas. Changed landscaping requirements in and around parking lots. Changed location of utility installations to prevent further disturbance of bioretention facilities in the future. Require adjoining property owners to maintain vegetation/landscape in public right-of-way in front of their property to the curb or to the edge of pavement.
