Bamboo


Leon and I were interested in planting trees, bushes and flowers to beautify the property and reduce erosion. We were able to get over 200 plants for free from the Department of Natural and Environmental Resources DRNA, mostly consisting of different varieties of palms and we bought hundreds of small mani plants for ground cover. Over time we continued to add different types of bushes, shrubs and flowers with some successes and some failures. Some of our favorite plantings are the various species of bamboo we planted on the east side of the property. We heard there is a man in town that goes by the name Bamboo Joe. He has 12 cuerdas (approx 12 acres) in Barrio Cruces covered in bamboo and various hard woods that he planted himself. Bamboo Joe was offering a tour of his property for anyone interested in seeing what he was doing. It turns out he built his house out of bamboo as well as furniture, lamps, toys, and tree houses too! Joe has created his own bamboo jungle unlike anything I’ve ever seen.

We were so impressed with the beauty of the bamboo garden that decided to hire Joe to plant bamboo on our property, Dos Ceibas. We already had one large patch of bamboo on the property that's been there for many years and it’s a special spot on the property for us. In fact we named one of the lots “Bamboo” because of it. The tranquility and shade it provides is a unique aspect of the bamboo patch. We love the noise it makes when the wind rusltles the leaves and makes the stalks rub against one another. The fallen leaves also provides a unique ground cover. We planted various types of bamboo as a screen on the north side of the property which has the closest proximity to a neighbor. We're looking to create a natural barrier on the border of the cano.

Here are a few species of bamboo we planted:

Bambusa Textilis, also called weavers bamboo. It's wind tolerant, compact, ideal for hedges and can grow up to 40 feet in height.

Bambusa Vulgaris, also called common bamboo has feathery yellow and green leaves. Its known to be great for erosion control and can grow up to 40 feet in height.

Dendrocalamus Asper, also known as giant bamboo can grow up to 4o feet in height. It has spines and sharp edges and grows really fast with large bright green leaves.

Bambusa Tuldoides is also known as buddhas belly because of the swollen sections called internodes. Buddhas Belly can grow up to 70 feet tall with zig zagging lowers culms! It's one of the largest bamboo species around. Obviously these are great for foliage and a privacy screen The height can also be stunted when put into pots and used for ornamental decorations.

Streetlights - Neighborhood Planning

One of the most critical decisions in planning the Dos Ceibas neighborhood was the placement of the road. The undeveloped land was a 4 acre parcel with a ridge running down the center of the property -the only access to the site was along the southern border from road 413. With the exception of a few foot trails, most of the site was covered in thick vegetation and was difficult to navigate. Figuring out the ideal location of the access road was one of our first tasks in the design of the master plan.

After walking every inch of the site with machetes, we evaluated the possible options. The road would provide access to each of the lots, but would also be the service spine for utilities (water, electricity, cable and phone service) AND have to be lit by streetlights to comply with municipal codes. We constructed a 3d model of the site topography to test the extents of the light pollution from the anticipated streetlights. Below are the images from preliminary designs A and J.


Design A locates the road on the top of the ridge - roughly dividing the property in two. While this seemed like a straightforward solution to vehicular access, the downside was that half of the properties would lose their ocean view and all of the lots would experience nightime light interference.





Design J locates the road to the west, below the ridge - allowing all of the houses to occupy the ridge and taking advantage of the elevation for ocean views. This also located the streetlights in such a way that the natural topography of the site helped to contain the light pollution. We determined that Design J would be the basis of our master plan.

Caribbean Coralina

This is one of the best local materials we came across in our Puerto Rico building adventure! Coralina or Coral Stone is quarried from multiple locations in the Caribbean - our lot was sourced from our stone supplier in Puerto Rico, but originated from the Dominican Republic. Coralina is a sedimentary rock composed of compressed shells and corals rendering it with some interesting properties.


Coralina is a pale pinkish/orange stone that bleaches out to almost white with intense sun exposure. Due to its composition, many tiny air bubbles are trapped within its layers making this stone an excellent insulator. BigPrototype used the stone on all of the exterior surfaces of the Little Malibu House. On the upper deck the coralina insulates the bedrooms below - using a passive cooling strategy to reduce or eliminate the need for AC.

In addition to having exceptional insulating properties, the surface is wonderful for barefoot traction. The porous finish is not slippery and is the perfect material to use around the saltwater pool. It should, however, be grouted and sealed to maintain a pristine surface - the tiny holes will otherwise trap water and cause mildew.

To find out more or to buy coralina tile, contact Yaniel Merced from Northwest Rustic Tile at 787-882-0520 or go visit them at: Carr 2 KM 118.1, Interior Carr #110, Bo. Ceiba Baja in Aguadilla

Keeping Dirt in its Place


Puerto Rico's coast is fringed with coral reefs and Rincon is home to one of the healthiest elkhorn coral communities in the Caribbean. Sediments that enter the water system and which end up in the ocean can kill corals by blocking the sunlight these reefs need to survive. There are many simple methods that can be implemented by real estate developers and home builders to reduce the amount of sediments that leave a construction site.

The easiest thing one can do in Puerto Rico is to do all earth moving during the dry season.

Home builders and contractors should install Sediment Control Devices like hay bales and silt fencing.

Another sustainable strategy to reduce sediments is to work with nature and plant in the disturbed area.

As soon as we had completed the grading for our road at Dos Ceibas in Rincon, PR, we planted over 2000 plants, shrubs and trees on the roadsides to help stabilize the soil and reduce erosion. These plantings are more than decorative, they are functional.

In this case, adding green is going green.
