My name is Michael and I started AVESI to inspire people to use their landscapes to create a better world. A world where less is wasted, biodiversity is revered, and natural resources are cherished.

AVESI’s custom landscape solutions are designed to manage drainage efficiently and sustainably by using a combination of traditional landscaping methods and modern Low Impact Development features. We have three guiding principles for all projects:

  1. Create functional, and sustainable landscapes
  2. Manage rain where it falls
  3. Help keep properties safe from water damage

I am proud to help people discover how to get the most out of their properties by applying an ecological approach to their landscapes.

Water is the most valuable resource that we have, and it’s our responsibility to manage it wisely. Please enjoy the website and feel free to get in touch with me!


testimonial_ballentine_photoAVESI specializes in custom drainage solutions. From diagnosis to planning and execution each landscape is customized to meet the drainage needs of each property while reflecting the aesthetic values of each customer. Landscape plans are designed to manage water as efficiently as possible using a combination of traditional landscaping methods with modern Low Impact Development (LID) features.

For larger, more complex jobs AVESI offers general contracting duties by coordinating tasks between highly capable and credible subcontractors. This includes scheduling and overseeing construction to ensure that plans are executed properly.

Subcontractors can be gathered from a wide range of services to deliver a complete package including:

  • roofing/eavestroughs
  • hardscape (driveways, patios, retaining walls)
  • basement waterproofing
  • property grading
  • tree services
  • plumbing


A rain garden is a shallow bowl shapes planted area designed to capture and absorb rain water. Typically planted with native shrubs, wildflowers, grasses, and ground covers rain gardens turn rain into a resource by absorbing water into the soil and helping to establish a healthy network of plant roots.

Rain gardens are ideal for solving drainage issues such ponding and erosion; while also creating habitat for native flora and fauna. A true marriage of form and function, rain gardens are completely customizable and can be designed to meet any desired aesthetic.

rain-barrel-installationRain barrels are one of the most popular tools for managing rain water at the property level. AVESI does all things rain barrel; from determining ideal location and size, to installation, and maitenance. Proper installation of downspout attachments and overflow hoses will ensure each rain barrel is working properly.

We create permeable driveways using a variety of engineered ego-grids specifically designed for vehicle and pedestrian traffic.

These geo-grids provide a high quality ground reinforcement system, are made from recycled plastic, are incredibly versatile, and are guaranteed with a 20-year manufacturer warranty.

The incredible versatility of these materials provide a solutions for every situation.



Downspouts are responsible for directing water away from your house so their arrangement can often be the most important part of any stormwater management plan. Many damp basements and soggy landscapes are caused by improper downspout arrangements.

The goal should be to find spaces on your property far enough away from the foundation where the water can be aesthetically incorporated into the landscape.

Rain arbors and pergolas are great for bringing downspouts over top of walkways or patios without causing a tripping hazard.

Catch basins and tile drains are great for catching water at grade where it can be directed away from the foundation into a rain garden or other feature.


No two properties are exactly alike, so no two gardens should be exactly alike. By carefully considering aspects like: desired aesthetic, available space, soil conditions, watering needs, location to adjacent buildings, and topography of the land each garden is custom designed and built.

Rain gardens double as pollinator and butterfly gardens. Planting native wildflowers, grasses, shrubs, and trees can enhance biodiversity on any property.


Harvesting rainwater can drastically reduce or eliminate the need to use municipally treated tap water.

Rainwater storage devices are available in a variety of sizes and styles and can be installed either above or below ground, depending on property conditions and customer preferences. They work great as a part of a larger stormwater management system.

Landscape erosion can take many forms. The common thread when experiencing landscape erosion is water concentrating in one place.

It is a worth while exercise to inspect your landscape for signs of erosion: bare or exposed soil, soil/debris deposits, slumping hardscape. Erosion is something that should be addressed as soon as it is detected.

Erosion can be addressed using simple measures like grading, planting, berms, and improving soil quality. There are a number of landscape products that address erosion and can be customized to fit the needs of each landscape.

The amount of living creatures (plants, animals, insects, etc.) that exist in a certain space. Healthier, more stable landscapes tend to have higher amounts of biodiversity. Changing or adding different types of plants can increase overall biodiversity of a space by attracting a variety of creatures such as birds, animals and insects. Native plants will attract native creatures.

Referring to the tightness or looseness of soil. Both infiltration and percolation are limited in soils which are overly compacted. Soils is gardens, especially rain gardens, should be loosened and non compacted to allow for proper drainage.

A downspout is ‘connected’ when it is fed directly into the city storm sewer system. Connected downspouts have been linked to flooding and sewer back up in urban areas, along with habitat destruction in local waterways. Redirecting downspouts onto a lawn, rain garden, or rain barrel is known as downspout disconnection. The water has to go somewhere so be sure to consider where the water would go before disconnecting a downspout.

Infiltration is the process of water absorbing into the soil. Many people attempt to solve drainage issues by direct water from one place to another when often the best approach is to let nature do the work by absorbing it into the soil.

Low impact development (LID) is a green infrastructure approach to stormwater management that uses simple, distributed, and cost effective landscaped features and techniques that helps reduce basement flood risks, clean and store stormwater, and helps residents conserve water. Conventional ‘Grey’ stormwater management approaches prioritize runoff, where newer Low Impact Development approaches prioritize infiltration.

Percolation is the downward movement of water through soil. Soil will act as a filter removing pollutants and regulating temperature of the water as it moves downward.

Permeable refers to a surface that will allow water to drain through it (infiltration). A surface that will not allow water to drain through it is known as impermeable. A natural permeable surface is a rain garden; but things like driveways, walkways, and patios can also be constructed as permeable surfaces.

A rain garden is a shallow landscape depression with well-draining biologically active soil designed to capture and infiltrate stormwater. Commonly planted with deep-rooted native perennials, shrubs, and grasses, rain gardens are best positioned near a runoff source like a downspout, driveway, or sump pump.

Rainscaping is the process of using one or a combination of features to manage stormwater as close as possible to where it falls, rather than moving it somewhere else. Features such as raingardens and bioswales use trees, shrubs, perennials, mulch, and healthy soil to intercept rain as it falls, and encourage water to infiltrate into the soil.

Also known as ‘runoff’, or ‘stormwater runoff’. It’s water that collects over impermeable urban surfaces like roads, roofs, driveways, and parking lots; picks up pollutants like oil, grease, bacteria, and hydrocarbons before draining into local waterways without treatment. Any amount of rain can generate stormwater; even melting snow is considered stormwater.
