Summary of Changes toGuidance for Comprehensive Transportation ReviewJune 2019 Version 1.0 vs January 2022 Version 2.0Aaron T. Zimmerman, PTPDDOT Site Development Program Manager

Process Flowcharts and CTR Requirements by Case Type Overview of DR ProcessPUDs, LTRs, Design ReviewsCampus PlansBZA CasesMap AmendmentsSite Design Review Priorities

Preferred Parking MaximumsNew 2022 Table2019 Table RevisedChange from 2019: Revised methodology of Multi-family Residential and Hotels to match MoveDC mode share goal-based methodology ofOffice and Retail (85%, 80%, 75%, 65% non-auto by distance to transit). This results in a 0.05-0.10 spaces/unit reduction for Multi-FamilyResidential in all transit distances and a 0.05 spaces/1,000 GSF reduction for Hotel within ¼ mile of Metrorail category.New: clarified that sites within 1/8 mile of Metrorail Station entrance should start with zero parking and build a case for why any parking isnecessary. If parking is provided, amount should be close to ZR16 minimum (50% of 701.5).

Low Impact Development Exemption from CTR/TIA2019 Waiver Must be located within ½ Mile of Metrorail or ¼mile of Streetcar, Circulator, Priority BusMust meet parking maximum for ¼ mile categoryregardless of distance from transit100 or fewer total on-site parking spacesImplement Enhanced TDM PlanEnsure ped network is up to DDOT standardsalong walking routes to transitA minimum of two (2) EV charging stationsCurb cuts/loading meet DDOT standards or havebeen approved by PSC.Site meets all ZR16 bike parking andlocker/shower requirements.2022 Waiver Must be located within ½ Mile of Metrorail or ¼mile of Streetcar, Circulator, Priority BusMust meet parking maximum for transit distancecategory where the project is located100 or fewer total on-site parking spacesImplement Baseline TDM PlanEnsure ped network is up to DDOT standards ANDinstall at least 1 Vision Zero or non-autoimprovement along routes to other amenities.A minimum of two (2) EV charging stations only ifsite has 20 or more parking spacesCurb cuts/loading meet DDOT standards or havebeen approved by PSC.Site meets all ZR16 short-term bike parking andlocker/shower requirements but must exceed longterm bicycle parking requirementsTDM Plan tier changed b/c standardized Baseline Plan was strengthened, parking ratios reduced,and many of the Enhanced strategies were not applicable to low parking ratio projects.

Mitigation MatrixNew chart: Intended as a starting point for mitigation discussions for projects 500,000 GSF and smaller. There may besituations where it makes sense to deviate from this chart.Change from 2019: Parking supply category breaks increased from 10% and 20% to 15% and 25%, respectively. This is tobalance the reduced Residential and Hotel parking rates.

Transportation Demand Management (TDM) Clarified threshold that TDM Plans are required for all projects of 20 or more residential units/hotel rooms or10,000 GSF office, retail, commercial. The point where DDOT requires the TDM Plan depends on what process theproject goes through. Any projects that meet the size criteria will be required as part of the curb cut approval toimplement a TDM Plan (if there is a curb cut and a plan wasn’t required at ZC or BZA).TDM plans no longer required for relief of less than 5 vehicle parking spaces, per ZC 21-10 text amendmentAdditional strategies added to each plan, including:– New bullets regarding continued TDM enforcement after building occupancy– If a loading management plan was required, include a bullet in TDM Plan so on-site Transportation Coordinator is aware ofthat requirement too. Thresholds for TDM plan tiers changed from 10% and 20% over-parked to 15% and 25% over-parked due toreduction in some max parking ratios.To improve equity with access to fresh food, charging for parking at grocery stores is no longer required. All othertypes of retail must still charge for parking at market rates.Added sections on latest legislation (EV Charging Stations, Parking Cash-Out, Commuter Benefits Law)A minimum of 5% of long-term bicycle spaces to be designed for larger cargo/tandem bikes and 10% of spaces bedesigned with electrical outlets for e-bikes/scootersDDOT TDM Team and goDCgo have started going through all previously TDM plans approved by the ZC, BZA, andPS and will now begin coordinating with property owners to assist in implementing TDM program

Public Space Included graphic (Figure 8 Site Review Priorities) highlighting DDOT’s focus on site design/public realm designover moving vehicle traffic. Added list of controversial public space features requiring PSC approval Fresh guidance provided on common public space/streetscape challenges and greater clarity on specificdistances, standards, and sections of regulations. Art and tactical urbanism in public space, activation under bridges, and experimentation with other types ofactivation are encouraged and additional guidance provided. Added information on Building Restriction Lines (BRL) Added guidance on which design vehicles should be used for loading facilities to/from public streets Added a list of pedestrian safety best practices (see following slide)– Including closure of slip lanes, construct curb extensions, raised crosswalks, reduce curb radii, straighten out skewedintersections, add missing crosswalks & ADA ramps at T intersections.

Miscellaneous Added statement regarding equity in mobility options and the decision-making process.No longer require a paper copy of CTR submitted, all files should be electronic.CTRs, TIAs, and Transportation Statements must be performed by PE, PTOE, PTP, AICP, EIT, CTP, other ITE.Added guidance on design of private streets and ROW closure/opening actions. Minimum alley width 16 feet.Updated several sections to reflect 3 recent text amendments to the ZR16 transportation sections (ZC 21-04, 21-10,21-22) – changes such as reducing private drive aisle width from 20 to 18 feet to match DEM and removed parkingminimums for affordable housing units 80% MFI and lowerClearer guidance on situations when an on-street loading zone is appropriate and how to implement it.DDOT does not support long-term bike parking relief for new construction. DDOT encourages providing extra longterm bike parking b/c many residential buildings have waiting lists and established thresholds for the number of longterm spaces to have electrical outlets (10%) and be designed for larger cargo/tandem bikes (5%). DDOT to have amore “hands on” approach to bike room design.Added guidance on increasing or decreasing mode share/trip generation based on supply of veh parking.‘Big data’ sources such as cell data allowed in lieu of fresh TMCs if there is a major transportation disruption.TripsDC can be used as another source to help determine mode share for a project.Created new section on Pick-Up/Drop-Off Plans. Revamped RPP section and added VPP section.Added guidance on intersection monitoring in the Performance Monitoring section.Distances are measured “as the crow flies” unless there is a significant barrier like RR tracks, freeway, water.

Appendices Appendix A – Shortened CTR Scoping Form from 13 pages to 10 pages by removing paragraphs ofpolicies, now references the appropriate section of CTR Guidelines for further guidance. Appendix B – updated all weblinks, added prior DDOT research studies & new relevant District laws, andadded attachments: 1) public space projections chart, 2) Federal Parking Ratios, 3) District Freeways Mapfor IJR/IMRs, 4) Map of ZR16 curb cut prohibitions, 5) Maps of Future Street connections from MoveDC2014 that were left out of MoveDC 2021. Appendix C – provided clearer guidance on when in the development process a TDM Plan is required,other changes to the TDM Plans noted on the TDM slide of this presentation. Appendix E – strategies added to the sample LMP for projects with on-street loading zones. Appendix F – added scooter corral diagram. Appendix F1 – corrected some incorrect measurements on long-term bike parking section of Bike ParkingDesign (storage locker dimensions and cargo/tandem space widths) Appendix H – 1) added the signal timing/Synchro network request form, 2) cap added to the amount ofright-turning volumes (10%) that can be assumed to make a right-turn-on-red (RTOR) movement in Synchro
