511 S. OAK KNOLL AVENUE
The project is a four-story multi-family building with a fully subterranean garage. It will be built on a vacant lot. The site is situated in a multi-family high density residential zone. It is subject to the City of Garden standards. The RM-48 District allows 31.15 units which is rounded to 32 units as tne base density for Density Bonus. The project utilizes a 42.5% density bonus under the very-low income table for an allowed density of 46 units. Inclusionary
Housing requires 20% of the 31.15 units (6 units as
affordable). the affordable units include 5 very-low income units and 1 moderate income unit. The project includes a waiver of the Tree Protection Ordinance and a concession for height under the State Density Bonus program.
The building is laid out around a central courtyard common open space. Entry porches covered decks and balconies
provide private open spaces. An electric power sub-station is adjacent to the site. We are enclosing the hallways parallel to the sideyards to block the loud noise coming from the sub-station.
A contemporary style has been chosen for the proposed
building. The design and massing of the building
acknowledges adjacent historic resource, 541 S. Oak Knoll Ave.

February 14, 2025
RESPONSE (1) - LCRA
MODULATION AND ARTICULATION OF THE MASSING HAS BEEN REVISED TO BETTER ACKNOWLEDGE AND RESPOND TO THE TWO ADJACENT HISTORIC RESOURCES.
SLOPED ROOFS WITH TILE ROOFING AND TRADITIONAL ARCHITECTURAL
ELEMENTS SUCH AS VERTICAL SIDING HAVE BEEN ADDED TO THE ARCHITECTURAL
DESIGN (WITHOUT COMBINING SPECIFIC FEATURES) TO BE MORE COMPATIBLE TO THE OVERALL CONTEXT & WITH THE HISTORIC RESOURCES AT 541 S. OAK KNOLL AND 500 S. EL MOLIINO AVE.
RESPONSE (2) - LCRA
FACADE DESIGN HAS BEEN UPDATED TO PROVIDE BETTER CONNECTION WITHOUT OVERWHELMING THE EXISTING CONTEXT. THE COMBINATION OF PARAPET ROOFS AND SLOPED ROOFS ALLOW BETTER CONNECTION TO THE ADJACENT BUILDINGS.
THE ROOF EAVES AND CANOPIES PROVIDE SHADOW AND DEPTH ON THE BUILDING FACADE. DEEPLY RECESSED COVERED OUTDOOR SPACES (BALCONIES &
PORCHES) PROVIDE FURTHER CONNECTIVITY TO THE OUTDOOR ARES AND TO THE STREET.
RESPONSE (6) - LAGDW
THREE COMMUNAL OPEN SPACES AT THE MAIN GARDEN - PROVIDE (SEATING AT
PLANTERS, OUTDOOR KITCHEN / BBQ AND DINING / LOUNGE SEATING) RESPONSE (7) - LCRA
CRAFTSMANSHIP ELEMENTS - THE PROJECT INCLUDES DECORATIVE IRON WORK FOR BALCONY & STAIR RAILINGS. THE PROPOSED DESIGN IS A MODERN INTERPRETATION OF CRAFTSMAN DESIGN (SIMPLE GEOMETRY & MODULAR DESIGN).
THE FRONT AND SIDE GATES AND FENCE ALSO PROVIDE A UNIQUE GEOMETRIC PATTERN INSPIRED BY CRAFTSMAN ARCHITECTURE.
BUILDING ELEMENTS - THIS PROJECT INCLUDES NUMEROUS ROOFED BALCONIES SUPPORTED BY POSTS ON THE GROUND FLOOR. THERE ARE OUTDOOR LIVING AREAS (LOGGIAS) WITH ORIENTATION TOWARDS THE STREET AND MAIN GARDEN. IN
ADDITION WE HAVE AN EXTERIOR STAIRCASE ADJACENT TO THE MAIN GARDEN / ANCILLARY GARDEN.
RESPONSE (8) - LCRA
NEW STAIRCASE HAS BEEN ADDED AT THE FRONT OF THE BUILDING (NEAR MAIN
GARDEN / ANCILLARY GARDEN) TO ENCOURAGE PRIMARY ACCESS TO THE UPPER FLOORS BY THE PEDESTRIANS. VISUAL CONNECTIVITY IS PROVIDED BY LARGE OPENINGS INTO THE STAIRWELL.
RESPONSE (3) - LCRA
VISUAL CONNECTION BETWEEN THE PUBLIC RIGHT-OF-WAY AND THE MAIN GARDEN
HAS BEEN ENHANCED WITH THE REMOVAL OF THE OVERHEARD CIRCULATION (BRIDGE WALKWAY). ENTRY FEATURE HAS ALSO BEEN MODIFIED TO ALLOW MORE DIRECT VIEWS INTO THE COURTYARD AND GARDEN AREAS. FENCING AND GATES COMPLY WITH THE CODE REQUIREMENT FOR VISIBILITY.
RESPONSE (4) - LCRA
THE ENCLOSED CIRCULATION CORRIDORS AT THE OUTER EDES OF THE BUILDING HAVE BEEN MAINTAINED FOR (2) SPECIFIC REASONS.
1) PROVIDE PRIVACY TO ADJACENT NEIGHBORS FROM CORRIDORS. 2) DUE TO NOISE FROM EXISTING POWER PLANT SUB-STATION
LIGHT AND AIR IS PROVIDED FROM WINDOWS AND DOORS WITH BALCONIES AT THE ENCLOSED CIRCULATION CORRIDORS. THE FACADE TREATMENTS AT THE SIDES AND REAR OF THE BUILDING RELATE TO THE INTERIOR PROGRAM OF THE BUILDING.
RESPONSE (5) - LCRA
GROUND FLOOR UNITS HAVE BEEN REVISED TO PROVIDE DIRECT FRONT DOOR ACCESS FROM SOUTH OAK KNOLL AVENUE. SECONDARY ACCESS IS PROVIDED FROM THE CORRIDOR. FRONT PORCH ENTRIES HAVE BEEN FURTHER ENHANCED BY REPLACING SLIDING DOORS WITH WINDOWS.
