Why Arizona Retaining Walls Require Specialized Engineering

Arizona’s geography and climate create unique engineering challenges:

1. Expansive Clay Soils

Common in Phoenix and Tucson, expansive clay swells when wet and shrinks when dry—causing intense pressure on walls. Proper design, drainage, and reinforcement prevent cracking or collapse.

2. Caliche Layers

Arizona’s hard caliche deposits complicate excavation and foundation anchoring. Experienced engineers know how to design footing and drainage systems that handle these conditions.

3. Extreme Temperature Swings

Arizona’s pavement can reach 160°F in summer and drop below freezing in winter. Licensed engineers use the right materials, joints, and reinforcements to prevent thermal cracking.

4. Monsoon Drainage

Sudden monsoon storms can dump inches of rain in hours. Without professional drainage design—weep holes, gravel backfill, and perforated drains—walls can fail quickly.

5. Seismic Stability

Arizona’s mild but present seismic activity requires that taller walls include earthquake-resistant design principles.

---

Types of Retaining Walls Common in Arizona

Cantilever Retaining Walls

Best for 4–20+ foot walls. Require complex calculations for reinforcement and footings—always handled by licensed engineers.

Gravity Retaining Walls

Ideal for decorative or shorter walls (under 4 feet). Even small walls benefit from professional drainage and soil design in Arizona’s expansive soils.

Segmental Retaining Walls (SRW)

Popular in residential and commercial Arizona landscapes. Most cities require an engineer’s stamp for walls over 4 feet.

Anchored / Tieback Walls

Used for steep sites or large commercial projects. These always require comprehensive retaining wall engineering services for safety and stability.

---

The Arizona Retaining Wall Engineering Process

Step 1: Site Assessment & Consultation

Your engineer visits the property to evaluate soils, slopes, and drainage, then recommends the best type of retaining wall for your Arizona location.

Step 2: Geotechnical Investigation

Soil borings and lab testing determine bearing capacity, lateral earth pressure, and drainage recommendations. Cost: $800–$2,500 for residential projects.

Step 3: Structural Design

The engineer performs load calculations and designs for overturning, sliding, and bearing stability. Drainage, weep holes, and backfill are included.

Step 4: Construction Documents & Stamped Plans

Your engineer provides sealed drawings and calculations that meet Arizona building codes—required for permits.

Step 5: Permit Application

Plans are submitted to your local city or county building department (Phoenix, Chandler, Mesa, Tucson, etc.) for approval.

Step 6: Construction Oversight

Engineers may perform site visits or field adjustments to ensure construction follows approved plans.

Step 7: Final Inspections

Your retaining wall is inspected and approved by Arizona authorities before it’s finalized.

Schembri Engineers offers expert inspections across metro Phoenix, delivering peace of mind with Certified Home & Property Inspection Services.

---

What Are Load-Bearing Walls & Foundations?

A load-bearing wall supports weight from above (floors, roof, beams) and transfers those loads into the foundation. Unlike partition walls, removing or altering them without proper design can compromise structural integrity. The foundation anchors your home and resists forces like soil settlement or uplift; problems here often manifest as cracks, tilts, or uneven settlement. In Phoenix, expansive soils and desert conditions can exacerbate foundation stress.

---

Signs You Should Call an Engineer

You don’t need to wait for disaster. Here are warning signs that merit professional inspection:

Symptom	What It May Indicate
Wide (> ⅛ in) or diagonal cracks in walls, especially near corners or windows	Structural shifting or foundation movement
Sagging or bouncing floors	Deflection in beams, joists, or inadequate support
Cracks in the foundation slab or footing	Foundation failure or soil pressure
Doors or windows that stick	Frame movement due to shifting walls
Bulging walls or separation between wall and ceiling	Lateral load issues or soil pressure
Settlement near footings or exterior walls	Soil subsidence or drainage-related erosion

When these symptoms appear, it’s best to schedule a structural inspection promptly.

---

The Role of the Engineer vs. a Contractor

• A contractor can do repairs—fix cracks, underpin foundations, install beams—but is not always qualified to assess or design structural systems.
• A licensed structural or civil engineer can diagnose root causes, perform load calculations, design structural solutions, and stamp plans for permit review. In Phoenix, adhering to municipal codes is critical. Before removing or altering load-bearing walls, an engineer’s design is often required to satisfy permitting procedures. Vir Structural Engineers

Hiring the right qualified engineer up front ensures your repairs are safe, sustainable, and code-compliant.

---

When You Should Definitely Call an Engineer (Phoenix Edition)

1. During remodeling, additions, or wall removal – Anytime you plan to remove or punch through walls, especially load-bearing ones.
2. Before buying a home – Structural inspections can reveal hidden foundation or wall issues.
3. When cracks or movement appear – Elevated, spreading, or recurrent cracks should be evaluated.
4. After natural events – If a storm, flood, or seismic event occurs, inspect structural components.
5. Pre-permit work – Many Phoenix municipalities will reject permit applications without stamped structural plans.

---

What to Expect from a Structural Inspection

A professional inspection will typically include:

• Visual and in-person examination of walls, beams, and foundation
• Review of original construction documents (if available)
• Measurements, mapping of cracks, and load path checks
• Structural calculations (axial, bending, shear)
• Recommendations and design options (repairs, reinforcements, load redistribution)
• Stamped drawings for repair or retrofit
• A clear report you can use with contractors or for permitting

When it comes to remodeling or renovating your Arizona home, one of the most critical questions is: “Is this wall load-bearing?” A misstep in removing or altering a load-bearing wall without proper evaluation can lead to costly—and dangerous—structural failures. That’s why homeowners in Arizona should understand the essentials of load-bearing wall evaluations, the risks involved, and the role of expert engineers in ensuring your home remains safe, sound, and code-compliant.

---

What Is a Load-Bearing Wall?

A load-bearing wall carries weight from the structure above (roof, floors, upper walls) and transfers that load down to the foundation. Unlike non-bearing or partition walls, load-bearing walls are integral to your home’s structural integrity. Removing or modifying them without accounting for their load path can lead to sagging floors, cracked ceilings, or even collapse.

---

Why Load-Bearing Wall Evaluations Are Especially Important in Arizona

Arizona’s unique climate and building styles make load-bearing evaluations especially crucial:

• Heat and expansion: The desert heat causes expansion and contraction in building materials, stressing structural components over time.
• Seismic considerations: While not as seismically active as some states, Arizona’s occasional tremors (and building code requirements) demand careful structural design.
• Older homes or unrecorded modifications: Many Arizona homes were altered over the years—without permits or professional guidance. Walls that once were non-bearing may now carry unexpected loads due to prior modifications.
• Material types: Masonry, adobe, block, or concrete walls behave differently from wood-framed walls. Knowing how to evaluate each type under Arizona conditions is essential.

Because of these factors, Arizona homeowners cannot rely solely on experience or guesswork—they need qualified structural evaluations.

---

Key Steps in a Load-Bearing Wall Evaluation

1. Review architectural and structural plans (if available).
   Original blueprints may indicate which walls are load-bearing. But in many homes, plans are lost or modified, so they’re just a starting point.
2. Inspect framing and structural members.
   Engineers or inspectors will look at joist directions, beam placements, column alignments, and connections to determine load paths.
3. Probe or remove finishes (where needed).
   In some cases, drywall, plaster, or finishes may be partially removed to reveal framing behind walls.
4. Check foundation and roof/upper loads.
   The wall must be tied into appropriate foundations, and the load from above must be quantified (roof, second floor, mechanical loads, etc.).
5. Perform calculations and verify load capacity.
   Engineers calculate axial, shear, and bending forces to confirm whether the wall or proposed modifications are safe.
6. Design reinforcements or alternative load paths (if needed).
   If removal or alteration is planned, beams, headers, steel posts, or other structural members may be designed to carry the load safely.
7. Permit and code review.
   Any changes must comply with Arizona building codes, local jurisdiction requirements, and structural safety standards.

---

Common Misconceptions & Risks

• “Because it’s just drywall, it’s non-bearing.”
  Not true. A wall may look ordinary, but behind it could be critical framing.
• “I can just add a header.”
  Headers must be sized correctly and properly supported. An undersized header or unsupported ends can fail.
• “Load shifts will always go to footing automatically.”
  Without proper design, loads can shift erratically, overstressing neighboring walls or structure.
• DIY is fine for small changes.
  Even minor adjustments to load paths can have cascading consequences. A professional evaluation is worth the cost.

---

When Should You Get a Structural Evaluation?

• When removing, relocating, or recessing a wall in a renovation
• When converting a single-story to a multi-story or adding mezzanines
• When purchasing a home and signs of structural distress (cracks, sagging, uneven floors) are present
• Whenever the existing layout seems inconsistent with expected framing (e.g. beams in awkward places)

Early evaluation prevents costly surprises mid-project and ensures safety.

In Arizona, the right professional will possess the proper licensing, insurance, local experience, and a track record of reliable work—qualities you want to verify before signing any agreement. In this guide, we’ll walk you through the key criteria you should evaluate when selecting a structural engineer in Arizona, and explain why Schembri Engineers is a strong choice for your project’s structural needs.

---

Why Picking the Right Structural Engineer Matters

• The structural engineer determines how the building resists loads (wind, seismic, gravity) and ensures safety and long-term integrity.
• Mistakes or inadequate design bring risks: structural failure, costly modifications, code compliance issues, and liability.
• A properly licensed and experienced engineer saves you money in the long run by avoiding over-design or rework.

---

1. Confirm Licensing & Credentials

In Arizona, structural engineers must hold a valid Professional Engineer (PE) license in the state. When vetting:

• Ask to see their Arizona PE license number, and verify it via the Arizona Board of Technical Registration (BTR).
• Look for additional certifications or continuing education relevant to structural or seismic design.
• Confirm that structural work is within the scope of their license (some engineers are licensed only in specific disciplines or regions).

A licensed PE offers you legal accountability and ensures they are subject to professional oversight and discipline.

---

2. Ensure Adequate Insurance & Liability Coverage

Even the best engineers can err, so it’s essential to ensure:

• They carry professional liability (errors & omissions) insurance.
• They have general liability insurance and workers’ compensation (if applicable).
• Their contract clearly delineates responsibility, limits of liability, and what happens if designs must be revised.

This protects both you and the engineer in case unexpected issues arise.

---

3. Look for Local and Regional Experience in Structural Engineering

Arizona’s climate, soils, wind loads, seismic zones, and building codes differ from other states. You want someone who:

• Has designed structures in Arizona (or in regions with similar conditions).
• Understands local jurisdictions’ permitting, inspecting, and building-code enforcement (e.g. Phoenix, Tucson, Flagstaff, Verde Valley).
• Is familiar with Arizona-specific challenges (heat, monsoon wind, expansion/contraction of materials, soil expansion/shrinkage).

An engineer with local experience will foresee regional pitfalls and streamline the approval process.

---

4. Check Their Portfolio & References

A good structural engineer should be able to share past projects. Ask to see:

• Examples of buildings, houses, additions, or renovations they designed.
• References—contact prior clients and contractors to hear firsthand about their experience in communication, reliability, schedule, and adaptability.
• Evidence of successful permitting (i.e. their designs passed plan reviews without requiring large corrections).

Seeing real work gives you confidence in their capability and design style.

---

5. Evaluate Communication, Responsiveness & Collaboration

Technical skill matters, but so does working well with you, architects, contractors, and city agencies. Look for:

• Clear explanations of approach, assumptions, costs, and tradeoffs.
• Willingness to meet (in person or virtually), to walk you through the process, and to make revisions.
• Responsiveness—how quickly they reply to your questions or resolve design clarifications.

You’ll likely interact with them many times over the project, so trust and clarity are essential.

---

6. Assess Scope of Services & Deliverables

Different engineers offer varying levels of service. When comparing proposals, ensure you understand:

Service	What to Confirm
Structural design drawings	Are foundation, framing, connections, lateral loads, etc., fully engineered?
Calculations & load analysis	Are full stamped calculations included?
Coordination	Will they coordinate with architectural or MEP (mechanical, electrical, plumbing) drawings?
Permitting support	Will they provide submittal documents, respond to plan review comments, attend meetings?
Construction observation / site visits	Do they offer periodic inspections to verify that construction matches the plans?

Make sure the proposal is comprehensive and not “piecemeal.” Hidden costs or missing elements cause delays and unexpected fees.

---

7. Compare Fees—but Don’t Choose Solely Based on Low Price

Cost is important, but:

• Too low a quote may indicate the engineer is understaffed, cutting corners, or omitting critical services.
• Be wary of engineers who don’t give clear line-item proposals.
• Ask for a breakdown of fees (e.g. design, calculations, revisions, site visits).
• Think in terms of value: a trustworthy, thorough engineer may cost more up front but save money in rework, delays, or liability later.

---

8. Review the Contract Thoroughly

The contract should clearly specify:

• Scope of work and deliverables
• Fee schedule and payment terms
• Timeline and milestones
• Revisions and change orders
• Liability limits, indemnification, and insurance
• Ownership of documents
• How disputes will be handled

Never rely on vague verbal agreements.

Natural Area Open Space (NAOS) is a protected part of a property in Arizona that is permanently designated to remain in its native desert state. While a homeowner owns the land, it is subject to an easement that restricts any building, landscaping, or clearing, making it a critical consideration for anyone buying, selling, or renovating a home in the region.

Understanding the Importance of NAOS

If you’re a homeowner or prospective buyer in Arizona, particularly in a city like Scottsdale, understanding NAOS (Natural Area Open Space) is essential. It’s a key component of the state’s efforts to preserve the Sonoran Desert. Simply put, NAOS is a deed-restricted area on a property that must be left in its natural condition, completely undisturbed by human activity.

The easement means that within the designated NAOS, you cannot:

• Build new structures like pools, sheds, or additions.
• Grade, fill, or excavate the land.
• Clear, prune, or rake existing native vegetation.

The purpose of NAOS is to protect native vegetation, wildlife habitats, and natural drainage patterns. This not only preserves the beauty of the desert but also helps with flood control and maintains the area’s unique ecosystem.

Know Where Natural Area Open Space is Located on Your Property

Before you plan any home improvement project, it’s crucial to know if and where a NAOS easement exists on your property. This information is typically recorded with the county and can be found on a title report or the subdivision plat. Knowing the exact location is the first step in avoiding costly violations.

We often encounter situations where homeowners are surprised by NAOS restrictions. For example, we worked with a client who wanted to add a beautiful new patio and retaining wall to their backyard. Upon reviewing their property documents, we discovered a significant portion of their yard was in Natural Area Open Space . By understanding the easement early on, we were able to redesign the project to fit within the buildable area of the property, avoiding potential fines and the expensive process of seeking a variance.

This is where expert structural guidance is invaluable. A NAOS violation can be a major hurdle, but with the right planning, it doesn’t have to stop your project. Schembri Engineers specializes in navigating these complexities. We work with homeowners and builders to ensure that structural designs are not only safe and robust but also fully compliant with local regulations, including NAOS easements.

How We Help You Navigate

Navigating the rules and regulations around NAOS can be confusing, but you don’t have to do it alone. As Arizona’s premier engineering firm, Schembri Engineers has been providing structural design services since 1985. We have the expertise to help you with every stage of your project.

Introduction

A survey is a broad measurement and mapping of land, while a boundary survey focuses specifically on locating the exact property lines and corners of a parcel. In short, surveys show what’s on the land, and boundary surveys confirm where the legal boundaries lie.

---

What Is a Survey?

A survey is a broad term that refers to the process of measuring and mapping property, land, improvements, and topographical features. It may include:

• Measuring distances, angles, elevation changes
• Mapping physical features (such as structures, roads, trees, utilities)
• Identifying easements, rights-of-way, flood zones, or environmental constraints
• Producing maps or plats to show what’s on a property and its surroundings

Surveys can be required or helpful in many contexts: property purchase, site planning, construction, zoning compliance, land development, and even for obtaining permits.

---

What Is a Boundary Survey?

A boundary survey is a more specific type of survey. The focus is on determining the precise location of the property lines (boundaries) of a parcel of land. Key elements include:

• Locating (or re-establishing) boundary lines based on recorded deeds, plats, monumentation, and Title documents
• Identifying corners, property line markers, fences, walls that define ownership
• Verifying legal descriptions
• Determining whether structures or improvements encroach onto adjacent parcels

Boundary surveys are often needed for resolving property line disputes, subdividing land, obtaining mortgages, or ensuring that structures comply with setback requirements.

---

Key Differences Between a Survey and a Boundary Survey

Feature	General Survey	Boundary Survey
Scope	Broad: topographic features, improvements, elevations, utilities, etc.	Narrow: focused mainly on property lines, monuments, legal boundaries.
Purpose	Site planning, building design, environmental assessment, grading, drainage, etc.	Property ownership/legal issues, fences/setbacks, title insurance, subdivisions.
Legal weight	Can inform many things; may not be sufficient alone for resolving boundary disputes.	Usually used in legal, real estate, or title contexts; heavily based on deed/record evidence.
Deliverables	Topo maps, site plans, overall property layout, sometimes 3D data.	Plat or map showing boundary lines, monuments/corners, legal description confirmation.
Typical Cost & Time	More elements = more work. Often more expensive due to more data gathering (elevations, utilities, terrain).	Sometimes less expensive if only lines; but if monuments are missing or deed records are complex, cost and time can increase.

---

When You Need One, or Both

Often, a property project requires both kinds of surveys (or parts of them). For example:

• Buying property: you’ll often want a boundary survey to ensure what you’re purchasing matches legal record, alongside a general survey to assess topography and features.
• Building an addition: you need to know boundary lines (to obey setback laws), but also elevations, existing structures, utility lines etc.
• Subdivision or lot line adjustment: boundary surveys are essential to legally adjust lines; general surveys help with terrain, utilities, and infrastructure planning.
• Dispute resolution: boundary surveys are typically the main tool; general surveys can provide context.

---

When you look at building homes, infrastructure, or commercial projects, you may hear people use the terms civil engineer and structural engineer interchangeably. While these roles overlap, each has distinct responsibilities, training, and specialties. Understanding the difference can help you know exactly who you need on your team—and how Schembri Engineers can deliver both.

---

What is a Civil Engineer?

A civil engineer is typically responsible for the planning, design, construction, and maintenance of infrastructure projects. This includes:

• Site development: grading, drainage, utilities, roads, sidewalks
• Infrastructure systems: stormwater management, sewage, flood control, water supply
• Land use planning & transportation engineering
• Public works projects: highways, bridges, airports, dams
• Regulatory compliance: making sure designs meet local, state, and federal codes and permitting requirements

Civil engineers often look at the big picture—how a project fits within its environment, how to prepare a site, how to ensure access, manage water and infrastructure.

---

What is a Structural Engineer?

A structural engineer focuses more narrowly on the skeleton of buildings or other structures: the parts that carry loads and make sure the structure stands up safely. Core responsibilities include:

• Designing structural elements: beams, columns, foundations, trusses, load-bearing walls
• Load analysis: wind loads, snow loads, seismic loads, dead/live loads
• Material selection: steel, concrete, wood, or composite materials
• Ensuring structural integrity over time: durability, safety, serviceability
• Inspection & evaluation: checking existing structures, analyzing damage, designing repairs

Structural engineering is deeply technical—analysis, modeling, safety factors—all focused on making sure that a structure won’t collapse, deform excessively, or fail in extreme conditions.

---

How the Roles Overlap (and Why Both Matter)

There is overlap. A civil engineer designing a site must work with drainage and foundation considerations, which involves structural knowledge. Conversely, a structural engineer must understand the site conditions (soil, slope, loads) which often involves civil engineering. Good projects require coordination between both disciplines.

A few examples:

What is needed	Civil Engineer’s Contribution	Structural Engineer’s Contribution
Building a new commercial building on undeveloped land	Designing the site layout, grading, utility connections, stormwater flow, access roads	Designing the building’s foundations, framing, ensuring safe load-bearing design
Renovating an older building	Determining site constraints, utilities, permits	Inspecting load capacity, designing structural reinforcement

---

---

When Do You Need Each (or Both)?

Here are some scenarios:

Scenario	You Need Civil Engineering	You Need Structural Engineering	Both
Building a new house on a graded lot	✔️ site grading, utilities	✔️ foundation & framing	✔️
Replacing a retaining wall after soil erosion	✔️ site grading and drainage	✔️ structural wall design	✔️
Adding a second story to an existing building	✔️ permits, site impact	✔️ load capacity, framing reinforcement	✔️
Building a road or infrastructure (non-building)	✔️ primarily civil	—	✔️ if bridges or structures are involved

• Clearly define what you want: budget, timeline, functionality (e.g., parking, load-bearing requirements, seismic or wind concerns).
• Ensure you hire licensed professionals: structural engineers should be licensed P.E.s; inspections by certified inspectors. Schembri Engineers provides licensed Professional Engineers for designs and board-certified inspectors for evaluations.
• Talk about soil and site conditions early: poor soil types, steep slopes, expansive soils (common in parts of Arizona) & drainage issues can significantly affect both civil and structural design.
• Plan for inspections & evaluation, not just design: catching issues early (foundation problems, structural issues) saves cost and delays.

Civil engineers and structural engineers are both essential

Civil engineers focus on how a project fits into, impacts, and works with land, infrastructure, and environment; structural engineers ensure the safe, stable skeleton of what is built. When they work together, projects are safer, more efficient, more durable, and cost-effective.

At Schembri Engineers, you don’t have to choose one or the other—you get both. Whether you’re starting from the ground up or reinforcing existing structures, our team has the civil, structural, inspection, and evaluation expertise to guide your project from plan through construction and beyond.

If you’re planning a project in Arizona or Nevada and want engineers who truly understand both civil and structural demands, contact Schembri Engineers today. Let’s make sure whatever you build is safe, sustainable, and built to last.

Why Knowing These Mistakes Can Save You Money

Construction and design projects are expensive, but errors in civil engineering services—especially for residential or commercial properties—can dramatically increase costs through delays, permit issues, or even structural damage. Here’s what to watch for:

---

1. Overlooking Drainage and Flooding Risks

In Scottsdale’s unique desert terrain, insufficient drainage planning can lead to erosion, property damage, and expensive retrofit work. A proper site analysis and grading design—handled by Schembri Engineers—ensures water flows safely away from homes and foundations.

---

2. Improper Site Grading

Uneven slope calculations or failure to account for runoff paths often require costly regrading or stormwater corrections later. Our civil design and analysis team designs proper grading plans that protect your investment from top to bottom schembriengineers.com.

---

3. Skipping Local Code & Zoning Review

Arizona has specific requirements for flood zones, setbacks, and building loads. At Schembri Engineers—serving Scottsdale, Phoenix, Mesa, and beyond—we stay current on local building codes to ensure a smooth permitting process schembriengineers.com.

---

4. Underestimating Soil and Foundation Conditions

Failing to assess soil type—especially in sandy or rocky areas—can lead to foundation settling or expensive change orders. We conduct site-specific evaluations to match your foundation design with Scottsdale’s subsurface conditions.

---

5. Neglecting Structural Mobility and Expansion

High desert conditions mean significant temperature fluctuations. Without proper allowances, materials can warp or crack. We design expansion joints and movement considerations into our civil and structural plans to protect long-term integrity.

---

6. Mistaking Structural Design for Civil Design Needs

Civil design covers infrastructure like drainage, grading, and site layout—while structural focuses on load-bearing components. Fortunately, Schembri Engineers offers both, so your project stays coordinated and integrated from site to structure schembriengineers.com.
