JOwjOjL SUDAS Statewide Urban Design and Specifications Jowa - SUDAS What is SUDAS? • Statewide standard for common urban public works improvements in Iowa — Voluntary, use by governmental and private agencies • Owned by a formal non-profit corporation with a board of directors • Operated by the Institute for Transportation (InTrans) through contract with Iowa State University • To our knowledge, Iowa is the only state to have a program like SUDAS. J0Wj4jL SUDAS History • 1976 to 1989 Sixteen cities and two counties (Des Moines and surrounding area) joined together to develop the Des Moines Metropolitan Design and Specifications Manuals. Hired a consultant to manage the program. • 1995 The technology subcommittee of the Governor's Blue Ribbon Task Force (Cities, Counties, DOT), in order to maximize the benefits of Road Use Tax Fund expenditures, recommended: "Adopt common standards for construction specifications and construction equipment." • 1998 Manual use expanded to 34 cities forming the Central Iowa Committee to own and manage the manuals. Maintained consultant contract for updating. J0W!4jL SUDAS History • 2000 With more interest across the state, InTrans is chosen for development of the ownership, management, and financial plans for the SUDAS Program. • March 2002 Iowa DOT and the Central Iowa Committee (CIC) entered into contracts with InTrans to update and convert the CIC manuals to SUDAS Manuals. • May 2004 The Iowa SUDAS Corporation is created to provide statewide ownership of the manuals. • February 2005 The Central Iowa Committee transferred ownership of the manuals to the Iowa SUDAS Corporation. J0Wj4jL SUDAS Benefits of Statewide Standards • Uniformity of urban design and specifications across the state • Reduction of contractor confusion and mistakes due to differing specifications; encourages more bidders with tighter bids • Method for study and rapid statewide implementation of latest techniques and material use • Forum that allows state and local governments to collaborate with each other and industry • Allows better allocation of staff to projects — not updating their own specs • Mechanism to be proactive in research and studies for new and improved urban design and specifications JOW!OjL SUDAS Statewide Involvement • Users — cities, counties, Iowa DOT, consultants, contractors, material suppliers • Technical committees — 14 — e.g. sanitary sewer, water main, paving, etc. • District committees — 6 — Meet February, April, and October • Board of Directors — 38 members 1 Dlstdct3 District *a�oro l — Meet twice a year l DistdCt � District 6 � *ca mu * ict owa w Distdct4 DlaMct6 SUDAS Board Appointments • 9 from MPOs/TMAs — one from each • 6 district committee chairs • 6 APWA members — one from each district • 6 county engineers — one from each district • 2 consulting engineers (ACEC) • 6 Iowa DOT staff members • 3 from cities with populations > 100,000 ppl • Advisory: AGC, FHWA, DNR, Paving Associations J0Wj4jL SUDAS • � os ` v �5il R I. ti' w Is , ;ter 'Ninowim os`se Usage • Today there are over 1,325 Standard Specifications and 700 Design Manuals in circulation • Every Iowa city over 15,000 has the manuals • No actual count of what agencies have adopted the manuals as their standards since it is voluntary • Consultants, contractors, and material suppliers use the manuals and strongly support the program JOWjOjL SUDAS SUDAS Funding • Public agencies have a vested interest in the SUDAS program — Iowa DOT — Cities and counties, funding funneled through: • Transportation Management Agencies (TMA) • Metropolitan Planning Agencies (MPO) • Regional Planning Alliances (RPA) — Research (Iowa Highway Research Board, DNR) J0Wj4jL SUDAS SUDAS—Two Manuals SUDAS Standard Specificabons JOWIAL SUDAS Design Manual • Chapter 1 General Provisions • Chapter 2 Stormwater • Chapter 3 Sanitary Sewers • Chapter 4 Water Mains • Chapter 5 Roadway Design • Chapter 6 Geotechnical • Chapter 7 Erosion and Sediment Control • Chapter 8 Parking Lots • Chapter 9 Utilities • Chapter 10 Street Tree Criteria • Chapter 11 Street Lighting • Chapter 12 Sidewalks and Bicycle Facilities • Chapter 13 Traffic Signals • Chapter 14 Trenchless Construction JOWjOjL SUDAS SODAS ». cr�a 9e.de iwd n,*m sm,fi.j.o Pmgan JOII0 Design Manual • Compilation of information relevant to the design of urban public improvements • Nothing limits the designer's options in specifying new and innovative technologies and materials • Includes requirements for plan set organization and information that should be shown by type of project - e.g. water, paving, etc. JOW!OjL SUDAS Design Manual • Specifications are "Menu" specs, which leaves a number of decisions for the Engineer • Several sections identify actions that are needed by the design engineer to minimize confusion and errors by the contractors and/or extra costs for public agency — Items to be specified, incidental items, bid items JOWjOjL SUDAS Design Manual • Example from "Items to be specified" list: 5010, 1.08, C 50101 2.011 Al 11 b 5010, 2.01, Al 2 50101 2.011 B, 11 b JOW!OjL SUDAS Section 5010 - Pipe and Fittings Specify whether measurement of fittings will be made by count or by weight.

must focus on the needs of all users for the land use in the area J0Wj4jL SUDAS Complete Streets • Iowa agencies that have established Complete Streets policies: Algona* Harlan* Quad Cities MPO Carlisle Cascade Iowa City* Sioux City* Norwalk Cedar Falls* Marion* Spencer* Ames MPO Cedar Rapids* Mason City* Spirit Lake* Des Moines Muscatine* Waterloo* Dubuque Oskaloosa* Woodbine* Fairfield* Cedar Rapids MPO Johnson County MPO • Also Wellmark Blue Zone Sites • As of December, 2015 J0 SUDAS Roadway Design — Complete Streets • Complete streets design must involve the principles of context sensitive design • Designs must take into account many factors, some of which may be in conflict with each other — Number and types of users — cars, trucks, buses, pedestrians and bicyclists — Available right of way and adjacent land use —Available budget — Parking needs — Community desires JOW!OjL SUDAS Roadway Design — Complete Streets • Complete streets are designed to respect the context of their location — Facilities in rural areas will be different than in urban areas — Larger cities with denser developments will be more involved than smaller cities. — Most effective when neighborhoods are compact, complete and connected to work, schools and shopping — Land use practices of large tracts of single use (i.e. suburban residential) are less effective in encouraging walking and biking trips JOWIAL SUDAS Roadway Design — Complete Streets Design standards and guidelines for complete streets would involve discussions of various elements including: AASHTO geometric standards - design speed, lane widths, turning radii, design vehicle Transit facilities Safety/Liability Shared use paths MUTCD provisions Landscaping Street classifications/characteristics/vehicle volumes Traffic signals Bicycle facilities Sharrow lanes; designated lanes; separated lanes Pedestrian crossings Pedestrian facilities (PROWAG) On -street parking J0 SUDAS Roadway Design — Complete Streets • Some of the design elements are standards and others are guidelines —The Manual on Uniform Traffic Control Devices has been adopted as law and thus must be met. — Potentially different standards when federal and state roadways are involved compared to local streets — Guidelines generally have ranges to consider to meet the project needs — All are used to protect an agency from lawsuits JOW!OjL SUDAS Roadway Design — Complete Streets • Elements included in the design guidance: — Land use influences all elements of complete streets design — Functional classification relates to the number and type of vehicles (cars, trucks, buses) on the street — Speed is generally related to land use and classification • One of the complete streets principles is to slow the vehicles down and improve safety for all users, especially bicyclists and pedestrians — Design vehicle — generally a large truck; determines turning radii and lane width J0Wj4jL SUDAS Roadway Design — Complete Streets • Design Elements: (cont.) — Lane width can vary from 9 feet to 12 feet wide • Impacts capacity (3-7%) — if too narrow vehicles will stagger themselves • Too wide encourages speeding • Lane width must consider the presence of on -street parking, bike lanes, buffer areas, turn lanes, and volume of trucks and buses — Curb radii impacts turning trucks and pedestrian crossing distances — Bicycle facilities are a fundamental element of complete streets and provide opportunities for a range of users — connectivity is critical • Dedicated lanes — protected and buffered • Shared lanes • Shared use paths JYowa j SUDAS Roadway Design — Complete Streets • Design elements: (cont.) — On -street parking can calm traffic and buffer pedestrian & bike facilities — Sidewalks serve many ages and people with different physical abilities • Must meet PROWAG ADA requirements • Connectivity is critical to encourage users — Turn lanes, including Two Way Left Turn lanes — Medians provide potential pedestrian refuge areas —Transit systems, if present, the location of stops and interaction with vehicles, bike lanes and pedestrian facilities is important JOWIAL SUDAS Roadway Design — Complete Streets • Design Elements: (cont.) — Traffic SivaIs • Direct impact on delay, improving traffic flow without widening streets, and controlling operating speed along a corridor • The pedestrian crossing phase should be set to allow elderly and physically challenged time to cross — current standard is 3.0 feet/second and recommended is 2.7 feet/sec. • ADA accessible elements such as audible and vibratory indications should included in all new signals or added to existing when upgraded JOWjOjL SUDAS JowjojL SUDAS Statewide Urban Design & Specifications Typical Adoption Process (2 Manuals) — Review current design standards and specifications — Design and specification modifications/revisions — Determine other impacts — Adoption by City Council Typical Adoption Schedule — Process often takes a year or more ,r CI1FOI OWACII� Statewide Urban Design & Specifications • Adoption Process—Specifications — Review current specifications • Complete — Supplemental specifications • Ongoing • Adoption Schedule — February 2018 ,r CI 1) UI OWACII� Statewide Urban Design & Specifications • Adoption Process — Design Manual — Review current design standards • Complete for Public Works • Next step: review with other City staff — Other impacts • City Code amendments — Design manual modifications • Ongoing • Adoption Schedule — April 2018 ,r �.®�, CI 1) UI OWACII� Major Projects Review . _illi'l .
