VMT Reduction and The Central Hercules Plan

-The Hercules New Town Center will result in VMT reductions of 50

to 70 million miles annually from the business as usual scenario for 2035 (2035 is the project build-out date). Business as usual scenario means not having a town center in Hercules.

-The long-term effect of the New Town Center will be to reduce VMT

by 50% from an average of 50 miles per household per day to

25 miles per household per day within the New Town Center's catchment area (catchment area is a 7-minute drive to the New Town Center).

-Over thirty years, reducing average daily household VMT by 25 miles will save consumers nearly half a billion dollars in gasoline. This is approximately $850 a year per household not spent on gas (assuming a real price of $4/gallon)

CalTrans Grant: Community Based

Transportation Planning Grant

“The City would like to build on the innovation of the updated General Plan

and on the success of the Downtown Specific Plan by updating the Zoning

Code..

These documents focus on accommodating and guiding development to

ensure compact, high quality projects that allow for higher densities, and

have created a solid foundation for smart growth policies and practices within

the City. The code will be a hybrid in that it will incorporate the principals and

philosophies of the Smart Code and Form-Based Code models.”

Alternative Energy Applications Along The Transect



• T3 Surface Drainage with High

Infiltration Potential – In this

lower density area where little to

no underground stormwater

infrastructure exists, Best

Management Practices (BMPs)

can be used to provide

opportunities to reduce

stormwater runoff, promote

infiltration and provide for

stormwater runoff treatment.

Appropriate practices may

include infiltration gardens,

bioretention areas, vegetated

swales, infiltration trenches and/

or level spreaders.

Refining the Application of Mixed Use


2-55-010 Purpose.

The purposes of the NM district are:

A. To designate areas for the location of a mix-

ture of neighborhood-serving businesses and resi-

dential uses;

B. To provide options for housing with ready

access to neighborhood shops;

C. To offer flexibility in subdivision design and

development;

D. To encourage a variety of housing types; and

E. To ensure that densities shall not exceed

those conforming to the general plan. In order to

achieve these goals and to enable the city to zone in

conformance with general plan densities, the NM

district is divided into the NM-1, NM-2, and NM-

3 zones. (Ord. 1736 § 2, 2004)

“Vertical mixed use is permitted and encouraged on site.”

Livermore, CA: Neighborhood MU Zone

• Min 25% of sites floor area

shall be commercial. Can be

100%.

• Commercial uses in conjunction

with residential development

shall comprise a minimum floor

area of 20 percent of the total

floor area up to a maximum of

30 percent.

• 1 space/ 500 sf

• Base densities: 1-3 du/acre to

24-38 du/acre

• No min. front setback. Max 20’

• Open space: 200 sf common,

100 sf private

Challenge: Refining the Definition of Mixed-Use


Refining the Definition of Mixed Use

General Plan Definition: Downtown Mixed Use:

This category includes residential, retail, office, public, and quasi-public uses…

How would this make you feel as a home owner in the neighborhood?

Its purpose is to encourage a mix of compatible uses adjacent to the Downtown, upgrading of existing buildings, preservation and adaptive reuse of historic buildings

Mixed use as the answer to everyone’s problems

“Mixed Use” includes the mixing of permitted activities within the same building or within separate buildings on the same site or on a contiguous site.

Common Mistakes to Avoid


9 Common Mistakes to Avoid

1. Thinking guidelines will achieve results without code reform

2. Doing a hybrid Form-Based Codes vs hybrid codes

3. Not lowering parking requirements for walkable urban areas

4. Not addressing street design and connectivity standards

5. Not refining land use tables

6. Using use as the Organizing Principle not physical form

7. Keeping Level of service (LOS) thresholds for urban areas

8. Trying to regulate walkable urban areas the same as

drivable suburban areas

9. Being too vague with mixed use application

“The key to substantial greenhouse gas (GHG)

reductions is to get all policies, funding, incentives,

practices, rules, codes, and regulations pointing in

the same direction to create the right conditions for

smart growth.”

“Growing Cooler” -Reid Ewing

Getting to Compact Development & Lower VMT


The Missing Middle

“Purpose..is to provide areas for the location of low density, multiple-family

residential dwellings..It is the intent that the district be used in the higher

density areas designated in the general plan..”

Form-Based Codes

"As global society swings into

action to reduce carbon

emissions, the data ever more

clearly points to the need to

reduce dependence on vehicular

mobility, and to remake the built

environment as transit- and

pedestrian-friendly places of

dense economic and social

interaction. Only the Form-Based

Code can ensure such an

urbanism.”

Form-Based Codes

A Guide for Planners, Urban Designers, Municipalities, and Developers

Daniel G. Parolek, AIA • Karen Parolek • Paul C. Crawford, FAICPForewords by Elizabeth Plater-Zyberk and Stefanos Polyzoides

Elizabeth Plater-Zyberk


“Sustainable Urbanism” Tools for Implementation

“By relating buildings back

to the street and open

spaces, rather than on

parking lots or private yards,

public spaces are redefined

from the conventional

automobile-oriented scale to

the human or pedestrian-

oriented scale. This focus

allows form-based codes to

guide the creation of active,

sustainable neighborhoods.”
