Engineering

CAPITAL IMPROVEMENTS
Capital Improvements include any design and construction of public facilties such as water mains, sewer mains, public roads and realignments of existing public roads, right-of-way acquisition, water and sewer main extensions, encroachment permits, and preparation of traffic control plans.

CONSTRUCTION MANAGEMENT
A consulting service of engineers that provide management for construction of final engineering plans. Construction management includes and is not limited to processing construction changes with the appropriate agencies, correspondence with agencies for approval of field changes, design changes based on field conditions, interdisciplinary coordination with other consultants during construction, as well as construction inspection as indicated on approved plans.

DRAINAGE PLANS
Related to Stormwater Management, minimizing downstream effects of erosion is addressed by not allowing increase in runoff. If runoff were allowed to increase, it has been demonstrated that the increase in runoff would create erosion in natural channels. Therefore, Standard Urban Stormwater Mitigation Plan (SUSMP) has been incorporated by local jurisdictions to prevent increase in post development runoff.

ENGINEERING STUDIES
An engineering study is a feasibility study for desired engineering scopes of work. The study would include research of existing topography, record documents, site visit, and any relevant jurisdictional information necessary to determine if a project is feasible.

FORENSIC ENGINEERING
Engineering services provided to explore existing engineered facilities, such as water lines, sewer lines, pad grading, construction of buildings, etc.. Typically, forensic engineering is used for expert witness testimony or for certification that construction was per approved engineering plans.

GRADING PLANS
An engineering plan of existing topography and proposed topography, including the calculation of earthwork movement.

HYDROLOGY/HYDRAULICS
Hydrology and hydraulics is the study performed to analyze surface runoff from storm events to a desired design point, including the conveyance of water through storm drain facilities. This type of study is necessary in order to satisfy various agency requirements as required by SUSMP.

IMPROVEMENT PLANS
An engineering plan for proposed road improvements including roadway design, public utilities, curb, gutter, and grading within the Right-Of-Way or private road easement.

PAVEMENT REHABILITATION
An engineering plan for the improvement of existing pavement. Work may include removal of the existing pavement and base to provide a new section or simply scarifying the surface of the existing asphalt and resurfacing. Pavement rehabilitation plans are prepared with the recommendation of a geotechnical engineer.

PRIVATE ROAD PLANS
An engineering plan for proposed road improvements including roadway design, public utilities, curb, gutter, and grading within the private road easement.

SEWER/WATER LINE PLANS
An engineering plan for proposed sewer and water main improvements.

STORMWATER MANAGEMENT
Within past few years, the State Water Resources Control Board (SWRCB) has mandated local jurisdictions to enforce land development projects to ensure that water runoff into existing storm drain systems are "clean" water. Stormwater Management is the means that jurisdictions have in order to enforce the Water Board's requirement. Stormwater Mangement plans vary per jurisdiction but essentially address the same issue of site design Best Management Practices (BMPs), source control BMPs and treatment control BMPs.

SUBSURFACE UTILITY ENGINEERING
SDE utilizes a systematic approach that considers the source of the existing underground facility information and its relationship to the overall project. The process is Subsurface Utility Engineering (SUE) as adopted by the ASCE.
