FOR RESIDENTIAL AND
NON-RESIDENTIAL
DEVELOPMENT IN WESTLAKE
MAY 13, 2019 PLANNING COMMISSION BRIEFING
PART 1: WHY WESTLAKE NEEDS THIS
TO ACHIEVE WHAT THE PRESENT DELIVERY SYSTEM DOES NOT ACHIEVE
•Most, not architects, untrained
•Plan set required for a permit is overly simplistic (Roof Plan, Floor Plan, General Elevations, Site plan, Electrical Plan.)
•Key decisions of style and quality made by the trade, not by an architect.
•Designer works for the builder.
PART 1: WHY WESTLAKE NEEDS THIS
TO PROTECT THE UNUSUAL PRICE POINT DISTINCTION OF THE SUB-MARKET
•Greater investment merited because of enduring value
•Residential sub-markets are defined by contextual distinctions = Natural Fabric, High Quality, Schools, Community Amenities, Population.
•What prevents the Westlake market from becoming assimilated by the neighboring sub-markets…Building Quality
PART 1: WHY WESTLAKE NEEDS THIS
TO MAKE THE MOST OF THIS
UNUSUAL OPPORTUNITY AND
THEREBY BENEFIT FUTURE
GENERATIONS
•70% unbuilt…no remediation
necessary…can create the vision
•Unusual residential land supply
in a context of land shortage for
higher end markets
•Economic development for the
emerging industrial cluster.
PART 1: WHY WESTLAKE NEEDS THIS
JOHN RUSKIN: When we build, let us think we
build forever. Let it not be for present delight nor
for present use alone. Let it be such work as our
descendants will thank us for; and let us think, as
we lay stone on stone, that a time is to come when
those stones will be held sacred because our
hands have touched them, and that men will say,
as they look upon the labor and see the wrought
substance of them, “SEE THIS OUR FATHERS
DID FOR US.”
The Building Quality manual is an essential
part of the Tool Kit through which the
Comprehensive Plan can be implemented in
a 100% zoned setting
PART 1: WHY WESTLAKE NEEDS THIS
Passed by Council in 2016
Adopted by Council in 2017
To Protect Submarket Distinction and Town Identity
Maintain distinction from the built fabric of other sub-markets
PART 1: WHY WESTLAKE NEEDS THIS
PART 2: THE MANUAL
DIVIDED INTO 6 SECTIONS
•Section1: Site Planning
•Section 2: Architectural Design
•Section 3: Site Treatment During Construction
•Section 4: Single Family-Residential Construction Quality Standards
•Section 5: Non-Single Family Construction Quality Standards
•Section 6: Protecting, Restoring, and/or Remembering the Indigenous Natural Fabric in Landscape Design
PART 2: THE MANUAL
Section 1: Site Planning Standards
•Mitigate tendency of site specific
development to be isolated and create a
fragmented Town Fabric.
•Consistent relationship between
development and the Public Domain
•Preservation of natural features and
systems
•Greater vehicular connectivity
•Vision of the Comprehensive Plan
PART 2: THE MANUAL
Example of Site Planning Standards
1.1: Relationship to, and Connection with
the Town Fabric
If located in an established context manifest
features of the context in the participating
development. Such as Street themes,
Continuity of water bodies, Continuity of
Road Section, etc.
1.3 Natural Fabric Preservation
Preserve or mitigate the loss of wooded
areas and significant trees
PART 2: THE MANUAL
Example of Site Planning Standards
1.9: Storm Water management Facilities
•Minimize structured means of water
management
•Maintain natural land shapes and forms in
the creation of detention/retention
facilities and created drainageways
•Restore and extend the natural fabric
•Respect natural sub-systems that flourish
within natural systems
PART 2: THE MANUAL
Section 2:Architectural Design
•Composition, Continuity, Articulation,
Style Integrity, Relief, Enclosure,
Addressing Ubiquitous Building Types
The Old Way of Seeing by Nathan Hale
When Town applied to design of the Fire
station
PART 2: THE MANUAL
Example of Architectural Design Standard
2.5: Articulation of Closure Details
Closure details (at openings, corners,
roof/wall junctures, and horizontal
offsets) are areas where design solutions
contribute to the detailed appearance of
an elevation. Therefore, the design of
buildings in Westlake must consider
closure details as an opportunity for
crafted articulation
A good example = Schwab
treatment of soffits
PART 2: THE MANUAL
Example of Architectural Design Standard
2.8: Retaining Grade
Retaining grade within the Architectural
Envelope as much as reasonable
2.10: Architectural Enclosure
All projected stairs, elevator shafts,
cantilevered building projections and bays
must be contained within an Architectural
Skin or expressed within the roof massing or
fully contained within a mass defined by a
larger form
PART 2: THE MANUAL
What happens when you do not enforce such principals
PART 2: THE MANUAL
Section 3:Treatments during
Construction and accommodation of
Site Facilities/ Service
•Site construction related practices
•Natural fabric and systems protection/
preservation
•Grading
•Screening
•Utility Services
•Loading
PART 2: THE MANUAL
Example of Treatment during
Construction
3.4: Tree Protection
•Tree fencing
•Tree marking
•Ground Compaction
•Maintenance of normal hydration
PART 2: THE MANUAL
Example of Treatment during Construction
3.5: Non-Residential Construction Quality Standards
•Grading Plan: Submit a grading plan for Town approval that identifies the existing topography and proposed topography after grading as well as any proposed grade retaining structures.
•Avoid Steep Grades: Any proposed grading which engages a natural slope of 15% or greater shall acquire Town approval.
•Grade within the Building Area: Grading within the Building Area identified on the approved grading plan.
•Conform to Tree Protection Standards
PART 2: THE MANUAL
Section 4:Single-Family Residential Construction Quality
•Building/Street relationships
•Foundation
•Walls
•Offsets
•Relief
•Materials/ Material Transition
•Trim, Openings, Roof, Style Details, Fire Places. Gates/Walls/Fences, Entries, Garage Doors, Wrought Iron
PART 2: THE MANUAL
Example of Single-Family Residential Construction Quality
4.9 Material Transition
Material changes in any elevation of a residential structure may only occur under the following conditions:
•Material change at an inside corner
•Material change that addresses an outside corner must wrap the corner and change at a location at least 12 inches from that corner as termination of an architectural detail/ element (such as a corner pilaster)
•Material change wherein the different material is contained within a distinct architectural form that projects from the primary architectural mass.
•Material change reflecting an off-set between a lower floor and an upper floor where the offset is at least 6 in.
Material changes within the same architectural plane are prohibited.
PART 2: THE MANUAL
Example of Single-Family Residential Construction Quality
4.5 Material and Material Use
Natural Stone used in Westlake must be laid in the veneer wall in a manner that replicates the coursing characteristics of load bearing stone work. “Coursing” means that the stones are:
•Generally laid in the wall as they would lay on the ground
•Consistently tight mortar joints…
•When the juncture of stones requires a large area of mortar, to maintain a level coursing pattern, smaller stones (called chinking stones) shall be used.
•Coursed stone patterns are generally acceptable...
•Cultured stone or other faux stone products are prohibited
•All stonework shall be laid in such a manner as to avoid stacked joints. ..have toothed corners
PART 2: THE MANUAL
•Section 5: Non-Residential Construction
Quality Standards
•Addressing ubiquitous building types
•Walls
•Openings
•Roof
•Parking
PART 2: THE MANUAL
Example of Non-Residential Construction Quality Standards
5.2 Walls:
•Wall Systems: Whether a modified frame or a load bearing masonry wall the offset between the exterior wall plane and the surface of any window or door shall be a minimum of 8 inches. Where masonry spandrel systems are employed for taller buildings, such systems must provide the same relief.
•Wall Finishes
•Control/Expansion Joints
•Masonry Materials
•Non-Masonry Materials
•Glass Structures and Horizontal relationships within the wall
PART 2: THE MANUAL
Section 6: Landscaping
