Understanding the types of terrain in Las Terrenas is essential before investing, building or developing a project in this vibrant area of Samana. Its particular coastal and mountainous relief, along with diverse soil types, directly influence earthworks, costs, foundations and architectural design. In this detailed guide we explain the main terrains, their suitability for construction and how to plan with technical knowledge.
Typical relief and topography of Las Terrenas
The topographic map of the area indicates an average elevation between 75 and 98 m above sea level, with maximums close to 400-500 m in the interior hills. The Samaná peninsula is dominated by a low mountain range that emerges perpendicular to the coast: the Sierra de Samaná, composed mostly of metamorphic and limestone rocks. This configuration generates a rugged terrain in the interior, gentle hills at the foot and coastal plains along beaches such as Cosón, Las Ballenas or Bonita.
Soil characteristics and their impact
1) Coastal and alluvial soil
It presents fine sands, well selected, with high permeability and low water retention -typical of sandy areas near the sea. It behaves well, but requires geotechnical studies for approximate foundations to the beach or dunes.
2) Hillocks and intermediate lands
Low hill formations with clayey silt or loamy soils, mixed with tropical vegetation. Their bearing capacity varies and a compaction study is necessary when carrying out earthworks.
3) Tropical forest and low mountain soil
Composed of weathered limestone with karst systems, cracks and subway cavities-especially towards the interior highlands. This influences ground stability and may require deep foundations or dissipators.
Earthworks: what to consider
When it comes to earthworks, knowing the types of land in Las Terrenas is fundamental. In hilly or wooded areas, it is common to clear vegetation, level terraces and compact soil before building. Drainage must be designed to avoid erosion and remain in ditches suitable for the rainy season -which exceeds 2000 mm per year in the highlands. In coastal areas, it is often necessary to fill or stabilize sandy soils for buildings.
Types of land by geographic location
- Coastal plains (Playa Cosón, Las Ballenas, Bonita): almost flat terrain, ideal for light construction; require study of salinity and soil behavior.
- Middle zone and interior hills: gentle slopes (5-15 %), good drainage, suitable for villas with views; moderate earthworks.
- High hills and hills towards the mountains: slopes up to 20%, karst soils, with risk of landslides; require geotechnical expertise and technical drainage.
Recommendations for building according to terrain
- Always carry out a prior geotechnical soil study.
- In sandy areas, pre-compact before cementing.
- In hills, use pile foundations or isolated footings.
- Places storm drains and slope containment systems.
- Take advantage of the topography: sea views, cross ventilation, passive design.
