B+W specializes in Hillside grading for single family residential throughout Los Angeles.


A Civil Engineering plan (designated as ā€œCā€ Sheets) shall be required for all new development constructing improvements within the public right-of-way. ā€œCā€ Sheets shall be submitted separately from the Building Permit plan set for review by the Department of Public Works, concurrently with Building Department review.

Erosion Control Plans

Wet Weather Erosion Control Plans show the minimization of the areas of disturbed soils and the duration of exposure during construction. This assures grading work on private or public projects does not result in soils or other material being washed from the construction site onto other properties or into water courses.

Excavation Plans

Excavation Plans show limits of the excavation (cut slopes, shoring, or a combination of both), adjacent streets and/or alleys with dimensions, and cross sections at various locations to show excavation details.

Grading Plans

Grading Plans shall include; property lines including public right-of-way to centerline of the street, all fully dimensioned, proposed building footprint and all structures, topographic survey of the private lot and the public right-of-way, sidewalks, curbs and gutters, handicap ramps, edge of pavement, parkways and driveways, storm drain devices including curb outlets, catch basins, on-site and off-site drainage with area drains, roof drains and flow direction.

LID - Low Impact Development

LID is a stormwater management strategy that seeks to mitigate the impacts of increases in runoff and stormwater pollution as close to the source as possible. The use of natural systems such as infiltration, evapotranspiration, and use of stormwater are promoted by a set of design approaches and Best Management Practices (BMPs).

Retaining Wall Plans

Structural Engineering is a specialty within the Civil Engineering field that analyzes and designs a structure such as a building, foundation plans or retaining wall plans. Safety is important as these structures are often subjected to extreme forces such as temperature, weather, dynamic loads, and earthquakes.

Sump Pump Design and Calculations

Design Sump Pump systems and calculations to convey stormwater from the existing property to the street. A sump is defined as a low area which prevents the free passage of water, and results in flooding of streets or private property. Generally, gravity flow drainage facilities may be installed for sumps; however, there are some drainage situations which would require the use of a sump pump.

SUSMP - Standard Urban Stormwater Mitigation Plans

SUSMP, or Standard Urban Stormwater Mitigation Plan, was developed to address stormwater pollution from new developments and redevelopment projects.
