ENGINEERING SERVICES

From site questions
to a workable plan.

Civil engineering for residential land development in San Diego and Riverside Counties.

PLAN A NEW PROPERTY

Know the constraints
before detailed design.

Review access, landform, drainage and wastewater needs alongside your intended use. Early engineering questions help define what to investigate and which plans belong in the project scope.

  • Available surveys, records and site constraints
  • Wastewater feasibility and testing needs
  • Grading, drainage and infrastructure requirements
Discuss a new-property plan

IMPROVE AN EXISTING PROPERTY

Make the next change
fit the whole site.

Consider how an addition, access improvement or landscape-water project relates to existing grades, drainage and wastewater systems. Establish the civil scope before committing to improvements.

  • Existing conditions and proposed changes
  • Drainage, soil and water-system relationships
  • Priorities, constraints and an appropriate sequence
Discuss property improvements

SOLVE DRAINAGE OR SEPTIC ISSUES

Define the problem.
Choose the right next step.

Start with what you have observed, when it occurs and any available plans or agency comments. Determine what testing, calculations or specialist investigation is needed before selecting a solution.

  • Observed drainage or wastewater concerns
  • Existing documents and missing information
  • Investigation needs and possible design scope
Discuss a drainage or septic concern
01

Septic & OWTS

Site and soil evaluation, percolation testing and septic system design for properties beyond the sewer network. Testing, design and permit documentation are defined for the property and its reviewing agency.

Percolation testing · System design · Permit documentation

02

Grading & drainage

Plans that bring the building pad, earthwork and surface drainage into one considered site design.

Cut-and-fill analysis · Drainage design · Erosion control

03

Stormwater & hydrology

Understand runoff and plan how water is conveyed, managed and treated across the site.

Hydrology · Detention planning · Water-quality design

04

Site feasibility

Explore site constraints and engineering needs before committing to the next stage of development.

Early site review · Development constraints · Project scoping

05

Street improvements

Engineering for the access and public-facing improvements that connect a project to its surroundings.

Road, curb and sidewalk design · Accessibility coordination · Utility coordination

06

Small subdivisions

Civil engineering coordination for residential land divisions and their supporting infrastructure.

Lot layout · Infrastructure design · Entitlement support

07

Water & landscape planning

Explore active roof-water capture, passive landscape harvesting and suitable graywater irrigation alongside soil-building and soil-management practices within the civil site plan. Potable-rainwater feasibility and keyline-informed terrain planning can be evaluated as separate, site-specific goals. The right combination depends on water sources, soils, topography, landscape needs and local requirements.

WHEN THE NEXT STEP IS NOT YET CLEAR

Start with a
scoped assessment.

An initial assessment can help turn broad questions into a practical next step. Before work begins, the written proposal identifies the assessment area, information to review and which deliverables are included.

01

A property brief

Your goals, the available records, known conditions and the questions the assessment will address.

02

Findings and open questions

A concise account of observed constraints and opportunities, distinguishing evidence from assumptions and missing information.

03

Priorities and next investigations

The decisions to make first, additional testing or specialist input needed, and dependencies between improvements.

04

A path to defined work

A review conversation and an outline of the next engineering scope or phases, providing a basis for the next proposal.

Site visits, surveys, testing, calculations, specialist studies and construction documents are included only when stated in the agreed scope. Preliminary findings do not certify safety or guarantee an approval.

Discuss an initial assessment

These are examples of work included in the practice’s current service descriptions. The written proposal establishes which deliverables apply, along with agency requirements and any specialist coordination.

BEFORE YOU BEGIN

A little clarity
goes a long way.

The right scope depends on the property, the proposed work and the reviewing agency. Start with what you know; we can discuss what is still needed.

What should I bring to the first conversation?

Your site address or assessor's parcel number, a short description of the proposed work, and any available surveys, plans, prior approvals or agency comments. You do not need a complete package to begin a discussion.

What if I am still deciding whether a site is feasible?

Start with a feasibility discussion. Access, topography, drainage and wastewater needs can shape the scope of a project before detailed civil plans are prepared.

Does a civil plan guarantee an approval?

No. Requirements and approvals depend on the project and the responsible agencies. The engineering scope and review process should be confirmed for each site.

YOUR NEXT STEP

Let's start with the site.

A location, a goal, a few questions. That's enough to begin.
