Strategic Assessment

Overall Strategic Grade
C+
Exposed

Meaningful friction. Expect exposure to either population pressure, blast zones, or natural disaster risk. Consider buying a retreat property.

What does this tell us?

Our Strategic Assessment grades tactical survivability of an area. Major population centers, military targets, fallout zones, natural disasters, and border exposure all drive risk — lower exposure means a more defensible position in a crisis.

This is heavily inspired by Joel Skousen's Strategic Relocation book. Highly recommended you checkout the book ($)

Regional Safe Places

Below is our recommended "safe zones" in Iowa  and the surrounding area based on our strategic heuristics. For most people, it's unrealistic to live in a “safe zone” full-time due to work, family or other personal reasons. They tend to be more rural. However, many of these areas are perfect for second homes and retreat properties that double as a vacation home or even a short-term rental.

Strategic Assessment Analysis

Grimes, Iowa, sits in a strategic sweet spot that few relocators fully appreciate: close enough to Des Moines to access its infrastructure, yet far enough to avoid being caught in the blast radius of a major urban collapse. This Dallas County town of roughly 18,000 residents has grown fast over the past decade, but its layout—spread out, with ample farmland and low-density housing—gives it a resilience profile that many suburban boomtowns lack. For someone thinking in terms of civic unrest, supply chain disruptions, or even larger-scale disasters, Grimes offers a defensible base with real advantages, provided you understand its specific risks and plan accordingly.

Geographic position and natural advantages for long-term stability

Grimes sits on the western edge of the Des Moines metro, roughly 15 miles from downtown, which puts it beyond the immediate fallout zone of any urban-targeted event while still within a reasonable drive for supply runs or medical access. The town is positioned along the Raccoon River Valley, with the North Raccoon River flowing just south of the city limits. This gives residents access to a reliable surface water source—critical if municipal systems go down. The surrounding terrain is flat to gently rolling, typical of central Iowa, which means good agricultural soil and easy drainage, but also limited natural cover. The area’s elevation is modest, around 950 feet, so flooding is a concern near the river, but most of Grimes’ residential development sits on higher ground. The climate is continental, with cold winters and hot summers, but the growing season is long enough for serious gardening or small-scale farming. For a prepper, the key takeaway is that Grimes sits in a region with abundant water, fertile soil, and a moderate population density—none of which are true for most of the coastal or mountain West.

Risks, exposures, and proximity to fallout-relevant landmarks

The biggest strategic liability for Grimes is its proximity to Des Moines, the state capital and largest city in Iowa. In a scenario involving civil unrest, mass casualty events, or a coordinated attack, Des Moines would be a primary target. The city hosts the Iowa State Capitol, federal buildings, major hospitals, and the Des Moines International Airport—all potential points of failure or attack. Grimes is close enough that a large-scale event in Des Moines could produce refugee flows, supply chain disruptions, or secondary effects like power grid strain. More specifically, the town is about 20 miles from the Des Moines Water Works, a critical infrastructure node that could be targeted in a waterborne attack or contamination event. There are no nuclear power plants within 100 miles, but the nearest major rail lines and interstate highways (I-35 and I-80) run through the metro area, making them choke points for movement. Grimes itself has no major industrial or military targets, which is a plus, but its growth has brought new subdivisions that are tightly packed—anyone looking for true rural isolation should look further west, toward Adel or Panora. For the relocator, the risk is not that Grimes will be directly hit, but that it will be overwhelmed by the collapse of the metro area it depends on.

Practical resilience for a relocator: food, water, energy, and defensibility

On the practical side, Grimes offers a mixed bag. Water is the strongest asset: the North Raccoon River is a perennial stream, and the local water table is high enough that private wells are feasible in many areas outside the city limits. The city’s municipal water comes from the Des Moines Water Works, which draws from the Raccoon and Des Moines Rivers, so if you’re on city water, you’re tied to that system. A backup well or rainwater catchment is a smart investment. Food resilience is solid: Dallas County is one of the most productive agricultural regions in the state, with corn, soybeans, and livestock operations all within a 10-mile radius. Local farmers’ markets operate seasonally, and there are several small-scale producers selling eggs, meat, and produce directly. For long-term storage, the area has ample space for root cellars or cold storage in basements, which are common in newer homes. Energy is a weaker point. The grid is served by MidAmerican Energy, which has a decent reliability record, but the area is not off-grid friendly. Solar potential is moderate—central Iowa gets about 200 sunny days per year, less than the Southwest—but with battery storage, a household can cover basic loads. Natural gas is widely available, which is useful for heating and cooking during grid outages. Defensibility is the biggest question. Grimes is flat, open, and crisscrossed by roads. There are no natural chokepoints, no hills to hold, and no dense forests for cover. The town’s layout—typical suburban sprawl with cul-de-sacs and strip malls—makes it hard to secure a perimeter. For a single individual or a family, the best approach is to choose a home on the edge of town, near farmland, with a clear line of sight and a single access road. Properties along the river or near the Raccoon River Valley Trail offer some natural barriers, but don’t expect to hold off a determined group. The real defensive value of Grimes is its low profile: it’s not a place anyone would target, and in a crisis, most people will flee toward rural areas, not toward a suburb of 18,000.

The overall strategic picture for Grimes is one of calculated trade-offs. It’s not a bug-out location in the mountains, nor is it a fortified compound. What it offers is a base of operations in a region that is agriculturally self-sufficient, hydrologically secure, and politically stable—Iowa has a strong tradition of local governance and community mutual aid, which matters when systems fail. The proximity to Des Moines is a double-edged sword: it provides access to hospitals, supply chains, and transportation, but it also means that any major event in the capital will ripple through Grimes within hours. For the conservative relocator who wants to be prepared without living in a bunker, Grimes works if you treat it as a forward operating base—not a final redoubt. Stockpile food and water, invest in a well and solar backup, build relationships with local farmers, and have a secondary plan to move further west if the metro area collapses. The town’s growth has brought amenities, but also density; the key is to buy on the fringe, not in the core. In a world where the next crisis could be economic, political, or environmental, Grimes gives you a fighting chance without requiring you to disappear into the wilderness. That’s a rare combination, and it’s worth a serious look.
