2 DESIGN DEVELOPMENT GUIDELINES FOR SIX-YEAR TRANSPORTATION PLAN PROJECTS Clllm County.1 PURPOSE Projects included in the funded portion of the Six-yer TIP need to progress through severl phses prior to development of finl design nd construction of the project. The purpose of this policy is to provide generl guidelines tht will: Provide refinement of the gols for the project Assure continued public involvement throughout the project development process Assure design lterntives re developed nd considered Further identify nd define mobility (including multi-modl trnsporttion options), sfety, community vlues, nd environmentl fctors Propose guidelines tht will foster optimized design tretments within context sensitive design process Provide dequte cost estimtes upon which project decisions cn be evluted.2 DESIGN DEVELOPMENT GUIDELINES 2.1 Refinement of gols nd dditionl public input for project The project mnger (stff) or consultnt will continue to refine the gols for the project gthering dditionl ssessments, input, or dt s needed. Additionl public meetings will be held if significnt chnges re nticipted by the project mnger. The project mnger (stff) or consultnt will provide sttus updtes nd/or provide dditionl informtion throughout the project using some or ll of the methods listed below: Milings to those on n originl notifiction list nd others if the level of interest wrrnts dditionl milings to lrger portion of the community. Website postings. Follow up meetings. Typiclly, design lterntives, drwings or sketches nd sttus updtes will be provided. Timelines my be discussed. Reports from design dvisory tem, if formed, my be given. Additionl opportunities for public comment will be provided. For some projects, phone clls, mil, or e-mil correspondence my be used. Policy 416 Pge 1

3 Project mngers, engineers, consultnts, nd stff shll respond to direct inquiries during ll phses of project design nd during construction s well. This my be one of the best wys for individuls to obtin informtion concerning project nd for the designer to get meningful input nd discuss specific design issues with constituents. 2.2 Design Development When possible, the project mnger, engineers, stff, nd/or consultnts will work through design development nd permitting in one fiscl yer nd then, if pprovl is given through signing of CRP (County Rod Project) Resolution, proceed with construction of the project during the next fiscl yer or two. For reltively smll nd strightforwrd projects design development, permitting, nd construction my be done in one fiscl yer. Emergency projects my proceed on fster trck, while some complex projects with numerous permits nd grnt funding my tke longer. It my be necessry on some projects to do preliminry survey work to determine existing right-of-wy lines, elevtions, or other informtion pertinent to evluting project need nd scope. This informtion my be gthered prior to initil open houses, but, if not, could be done or expnded upon during design development. Prior to surveying to obtin ground mesurements or wetlnd delinetions needed for project design, letters will be sent to the property owners requesting permission from those whose lnd the county needs to enter. This does not pply to lnds where requests for permission is not expected (i.e. DNR lnds). The project mnger, stff, nd/or consultnt will develop rnge of design lterntives long with cost estimtes. Design lterntives will include list of dvntges nd disdvntges to ech lterntive long with cost estimtes. The project mnger or consultnt will present the design lterntives nd review the project sttus t public meeting dvertised nd set up s described in Policy 415, Section 2.4, s well s inviting those who hve sked to be kept pprised. The project mnger or consultnt will record in summry fshion comments received t the meeting nd study informtion received, giving considertion to suggestions or recommended lterntives. The project mnger will keep the County Engineer pprised regulrly nd solicit pprovl of concepts prior to spending time perfecting them, especilly for uncommon concepts. The project mnger or consultnt will give their recommendtion of preferred design lterntive long with ny other pertinent informtion to the County Engineer. The County Engineer my, t ny point in time, determine tht project is of sufficient size, scope, complexity, or hs specil design chllenges, such tht design tem should be ppointed to ssist with the project. The County Engineer my ppoint design dvisory tem whose size nd mkeup my chnge s the project progresses. The design dvisory tem my include representtives from some or ll of the res listed below, but is not restricted to those on this list: Policy 416 Pge 2

4 Project mnger, stff or other Rod Division stff Consultnts if hired for the project Homeowner s Associtions, or Neighborhood groups Emergency Response ( Emergency medicl personnel, mbulnce, fire, lw enforcement) Trnsit Commercil crriers or Delivery services (UPS, Construction, Product huling) Adjcent jurisdictions Tril nd multi modl interest groups Resource groups (Fish nd Wildlife, Historic Society) The County Engineer will set the scope of work, time frme, nd estblish funding guidelines for the design tem long with ny specil requirements tht need to be considered. The tsks my be ll of design development including refinement of gols for the project or just portions thereof. The design tem my hold dditionl public input meetings, site tours, or utilize other communiction methods to resolve issues or gin informtion pertinent to their tsks nd ssignment..3 FINAL DESIGN The project mnger nd/or consultnt will present their preferred lterntive nd finl design recommendtion to the County Engineer. If the County Engineer cn support the preferred lterntive from professionl nd budgetry stndpoint, he/she will present County Rod Project (CRP) Resolution tht provides for the engineering nd right of wy phses to the Bord of County Commissioners for pprovl. This CRP Resolution my contin construction phse s well. Once the CRP is pproved, right of wy, finl engineering, finl design drwings, specifictions, nd finl cost estimte will be developed for the project..4 CONSTRUCTION A resolution for the construction phse will be presented to the Bord of County Commissioners for pprovl, if not included with (3.2) bove. Construction will be mnged ccording to the contrct documents, nd other lws nd regultions pertining to public works projects. Policy 416 Pge 3

5 The County Engineer nd project mnger will strive to keep the public informed of work progress, schedules, nd mjor chnges in the proposed work through vriety of methods: News medi Posted signs Milings Personl clls nd contcts Internet postings.5 APPLICATION This policy pplies to rod projects developed under the funded portion of the Six-yer Trnsporttion Pln. It is not intended, nor does it pply to mintennce or preservtion projects or progrms, signge or trffic studies, engineering studies, dringe or culvert replcement projects, unsfe bridge replcement projects or 2R rod improvements. 2R improvements re resurfcing nd restortion projects..6 CONTEXT-SENSITIVE DESIGN GUIDELINES Definition of Context-Sensitive Design: CSD is collbortive, interdisciplinry pproch tht involves stkeholders nd design professionls to develop trnsporttion fcility tht fits its physicl setting nd preserves scenic, esthetic, historic, nd environmentl resources, while improving sfety nd mobility. CSD is n pproch tht considers the totl context within which trnsporttion improvement project will exist. Project design will consider the following context sensitive design guidelines: 6.1 Context-Sensitive Progrm Concept Develop plnning nd design process tht will result in development of Context- Sensitive Solutions for our rod projects, prticulrly mjor rod projects. The following four mjor res of considertion in CSD cn be broken down into mny smller components for considertion, depending on the size nd scope of the project nd the specific re in which it is locted: Sfety - Sfety concerns of users nd residents need to be crefully considered in light of Wshington s Tort nd Joint nd Severl Libility issues, locl City nd County Design Stndrds, or other pproved nd ccepted stndrds or guidelines. Policy 416 Pge 4

6 Preservtion of Community Vlues - Considertions of plnning nd zoning issues, neighborhood uses, historic vlues, lndmrk vlues, nd humn interests. Mobility - Trffic flow, considertions for ll trffic uses nd multi-modl trnsporttion issues. Considertion of the Nturl Environment - Fish pssge, rodside dringe, viewpoints nd esthetics, nd vegettion plntings nd control. 6.2 Context Sensitive Gols Design excellence with project optimiztion. Optimiztion with the understnding tht nerly ll projects will involve trdeoffs with our gol to optimize design tretments to the highest extent possible given funding, relities, nd other constrints. 6.3 The Chllenge There is no cookbook pproch or checklist tht covers CSD. The chllenge is to develop process nd level of community involvement nd cceptnce for ech project. The process should strive to build sfe, esthetic, environmentlly friendly, cost effective, efficient trnsporttion system, while giving significnt considertion to historic nd community vlues. 6.4 Why Consider CSD There re more nd more people residing in Clllm County nd these people re tending to drive more nd more. There re growing numbers of bicycle riders, horse riders nd wlkers tht use the trnsporttion corridors. The public is much more knowledgeble nd involved thn ever before with concern over projects tht ffect them or others. There is growing wreness nd concern over the effects projects hve on the environment, nturl resources, nd neighborhoods. Finlly, our finncil picture will dictte tht we do good job on the front end of plnning nd design to void spending money unnecessrily on designs tht won t work or be cceptble to the public nd decision-mkers. 6.5 Wht CSD Is It is working through collbortive, inclusive, interdisciplinry design process to come up with the best solutions. It my not be 100% consensus. There my well be rguments nd unresolved disgreements over two feet in width, whether tree should come out or not, but ll issues should be considered nd the best options possible, implemented. 6.6 Wht CSD Is Not Policy 416 Pge 5

7 It is not one-size-fits-ll process. It is process nd concept tht is worked through nd will evolve over time. It is not ignoring tested nd well-developed stndrds. It is developing pproprite design tretments within pproprite nd pproved design stndrds, but in flexible, esthetic, collbortive wy..7 CHECKLIST FOR PROJECT DEVELOPMENT CONSIDERATIONS The following list is to be used s guide when developing project design. Other fctors my need considertion nd this list is not intended to be ll-inclusive, just guideline. 7.1 Sfety Sight distnces Horizontl nd verticl curves Cler zones Competing uses Winter shding, icing Drivewy ccess nd culverts Speeds nd trffic counts Hzrds present Accident reports Emergency ccess Superelevtion nd crown rte Rodside slopes Mil crriers nd school buses stopped in the rod 7.2 Preservtion of Community Vlues Historic lndscpes, structures, or rcheologicl sites Scenic views or pull outs Fences or uses in rights of wy Demogrphics Comprehensive Pln issues Neighborhood vlues or tmosphere Historic lnd uses Economic ctivity nd vlue Reducing the rod scr Urbn look vs. rurl look Visul esthetics of improvements (e.g. fences, stormwter fcilities, etc.) Alterntive modes of trnsporttion (e.g. wlking, bicycles, etc.) 7.3 Mobility Rod width Multi-modl trvel Design stndrds Policy 416 Pge 6
