Site Design
Erosion Control Plans
As either a supplemental plan to a grading and improvement plan set or a stand alone plan for a development project, the engineers of KMLT have produced hundreds of approved erosion control plans for projects within The County of San Diego. These plans feature details, specifications, and callouts for all of the necessary construction Best Management Practices (BMPs) that should be implemented at a project site to help eliminate potential construction pollutants to downstream stormwater receiving facilities and bodies. These erosion control plans help ensure that a given development site is in compliance with storm water quality standards and if measures are implemented according to plan, will eliminate the possibility of potential fines issued by a state or local authority (Regional Water Quality Control Board) for being in violation of the Clean Water Act (CWA) established in 1972 and administered by the Environmental Protection Agency (EPA).
BMP/LID Site Plans
Infrequently, but sometimes required by an agency or municipality, a separate Low Impact Development (LID) plan may be requested as part of a civil plan set. Several of these plans have been generated by our staff and approved by various different reviewing entities. These plans feature post development structural stormwater pollution prevention facilities, from small scale to larger scale, such as treatment and mitigation basins to smaller scale infiltration units utilized to capture surface runoff and treat it via infiltrating into native underlying soil. The design of these facilities and the corresponding LID plans to exhibit them have been produced by our staff on development projects for over a decade.
Retaining Wall Plans
Developments within the County of San Diego often require a separate building permit plan set, specifically for retaining wall design. AT KMLT, we can develop your building permit retaining wall plans exhibiting plan view and profile views of walls to be constructed with top of wall and top of footing elevations. Our engineering staff specifies regional standard and city standard walls to the greatest extent possible. Should a site design call for a wall typically above 5'4" to 6 feet in height from footing to top of wall, or a steeper backfill slope greater than 1:5:1, or any other design parameter that requires a non-standard wall, a structurally designed wall will be needed for a given project. For non-standard structurally designed walls , we can subcontract out the structural design to a structural engineer, and then incorporate the structurally designed wall/walls back into our retaining wall building permit plan sets to cover the design of all site walls, standard and non-standard.
