Study basics

Implementing Subdivision Staging Policy Work Program

Coordinated with • PHED/Council consideration of SSP Amendment #14-02 for White Oak• Development of new trip generation rates

Element LATR TPAR

Scope Full consideration of options (similar to 2012)

Limited changes to transit performance calculations

Working group

~30-member TISTWG (monthly meetings)

Technical staff

Timeframe Initial recommendations fall 2015 followed by Planning Board and Council review through fall 2016


5

Study basics

• Building from best and emerging practices nationwide

• Balance of ideas and perspectives from agency, business, and civic representatives (ten meetings to date)


6

Key Objectives“LATR should be designed to implement the County’s plans”


7

Key ObjectivesImplementing and complementing other planning and zoning policies facilities evolution of all policies over time.


8

Key Objectives

• Three primary objectives• Improve multimodal

analysis, • Increase

predictability, • Streamline

implementation

• Three primary elements• Scoping• Analysis• Mitigation

• Multiple land use contexts


9

LATR Type Hierarchy

Pro-rata

share

• Where do we know what we want to build (both public and private)?

• Apply special districts

Negotiated Exaction

• Where do we want to emphasize ped, bike, transit?

• Apply equivalent mitigation approaches

Impact Mitigation

• Where do we want to achieve L/QOS standards (for any or all modes)?

• Apply modal tests


10

Pro-Rata Concept

private sector funding for total system

supplyPRO RATA SHARE = ----------------------------------------------------- unit of development demand

Simple, powerful, flexible concept.

Requires fairly extensive context-sensitive development:• What functional objectives should the system achieve

(i.e., how to define supply and demand)?• Geographic area?• Type/timeframe of improvements?• Interim monitoring / measurement?

Once established, private-sector participation is streamlined.


11

Balancing Objectives

Increased predictability in areas of greatest planned growth

Increased analysis in areas where growth less desirable

Philosophical Approach #1:Streamline growth in urban areas


12


Increased analysis in areas of greatest activity where multimodal travel demands and facility needs are greatest.

Philosophical Approach #2:Identify needed multimodal solutions in urban areas


13


Proposed approach: Increased analysis in areas of greatest activity where multimodal travel demands and facility needs are greatest, coupled with increased predictability in mitigation

Philosophical Approach #3:Balance between streamlining and analysis


14


Proposed approach: Develop additional pro-rata share districts (or equivalent approaches such as VMT or PMT fees) in conjunction with local community involvement and detailed study.

Evolution Over TimeShift towards Pro-Rata Share in smart growth areas


15

LATR Evolution

Currently, the County has:

• a pro-rata share approach in White Flint

• Alternative Review Procedures and guidance for preferential bike/ped/transit approaches in the other MSPAs / CBDs, and

• $12K/vehicle trip for non-auto solutions countywide

LATR Evolution

Pro-rata share approaches can be considered for any geographic area, but are most successful when combined with the planning and policy aspects of master planning.

New Special Taxing Districts are not necessarily needed, pro-rata share approaches can take many forms.

LATR Evolution

Bethesda may be a good candidate for the next pro-rata share district as its plan moves forward.

Many new negotiated exaction approaches are being developed.

These new approaches are also being considered now for the County’s remaining urban areas.

LATR Evolution

Other fixed guideway station areas can be added to the Urban Area construct. The CCT and Purple Line stations are ready for such consideration.

Over time, some or all of the other BRT network stations could be identified as Urban Areas and additional pro-rata share locations may emerge from local stakeholder interests.

Pro-rata share elements

Successful pro-rata share district elements:• Compact geographic area• Common stakeholder interests• Inventory of unbuilt transportation system and

private development• Reflects needs and interests of constituents• Coordinated with state, regional, and local

implementers and operators• Includes regular monitoring and revision

processes and schedules

Examples: Delaware TID, Florida MMTDs, special districts in Baltimore, MD and Portland, OR.

Very-Low VMT Concept

Type of Development

VMT effect Qualified as

Effect on existing tests

Type 1: Zero VMT Development

Reduces areawide VMT (only residential applications in Bethesda/Silver Spring with very limited on site parking)

Defined by lookup table in Planning Board Guidelines

No action under LATR, TPAR, or transportation impact taxes

Type 2: Very Low VMT Development

Limited VMT (only residential applications in Bethesda/Silver Spring with relatively limited on site parking

Defined by lookup table in Planning Board Guidelines

No action under LATR

Type 3: Mitigated VMT Development

Reduction of site VMT by 50% as negotiated in “hard” Traffic Mitigation Agreement

Negotiated Traffic Mitigation Agreement

No action under LATR/TPAR; additional transportation impact tax


21

Very-Low VMT ConceptType 1: Zero-VMT Development: Limit parking to <

0.16 spaces per dwelling unit (no additional parking for up to 15KGSF ground floor retail).

Type 2: Very Low VMT Development: Limit parking on sliding scale per table below (no additional parking for up to 15KGSF ground floor retail):


22

Suite of LATR revisions Scoping

• Primary measure person-trips, not vehicle-trips• Specific person-trip thresholds for auto, ped, bike,

and transit analyses and mitigation• Low-VMT Alternative Review Procedure• Identify “protected intersections” where no

further auto capacity to be added

Analysis• Bike/ped gap closure• Bike/ped accessibility incentives• Multimodal operations

Mitigation• Priorities: TDM, bike/ped, transit, auto

Next stepsLATR• Develop draft changes to LATR Guidelines (summer 2015)• Review / refine with TISTWG (fall 2015)• Develop final recommendations/report (winter 2015)• Present to Planning Board (early 2016)*

TPAR• Assess changes (summer 2015)• Review/refine with partner agency staff (fall 2015)• Develop final recommendations/report (winter 2015)• Present to Planning Board (early 2016)*

Trip Generation • Develop/refine approach (summer 2015)• Review/refine with partner agency staff (fall 2015)• Develop final recommendations/report (winter 2015)• Present to Planning Board (early 2016)*
