Green Building and Landscaping | Landscaping
The main access walkway is designed to draw people to the Village Square; however it needs to serve recycling and garbage trucks, fire engines, moving vans and other heavy vehicles. To avoid the negative visual effect of a wide expanse of pavement, a unique structural/planting system is used. It costs a little more than asphalt, but avoids having to manage run-off water and filters the rain. Other walkways use rubberized asphalt or porous asphalt to accelerate run off and reduce slipping.
While Bayview Village has much less pavement than a typical subdivision, it has more roof area, so the impermeable area may be about the same. The run off from roofs, however, would be cleaner than from a typical pavement, and can be retained in storm water ponds for irrigation and landscaping. Storm ponds capture and store storm water run off and function like natural ponds for maximum natural water supply. The site retains its normal storm water using a pond at the north park and at the wetland park.. The pond at North Park could be designed to retain a large amount from rain that would trickle down to a smaller more permanent pond, with a small water flow along the central path through the Village Square and on to the Wetland Park. It could have a large rain storage cistern, play pond, and/or meadow. Then, a Strom Water Pollution Prevention Plan would be needed. Perhaps this is a project that the Homeowners Association will take on in the future; that project could have a grey water system for landscaping, probably tied into the roof drains and storm water system.
Inside water use is reduced at Bayview Village. Appliances like water-saving dish washers and clothes washers, water conserving, low flow showerheads, and water conserving faucets effect water conservation. Dual flush toilets which have a toggle button on the top of the tank, one side for a 1.6 gallon flush and the other for a .9 gallon flush, also help conserve water.
Outside water use is reduced by avoiding over-watering, using native, drought-resistant plants, and avoiding use of water for cleaning sidewalks and cars. Water pollution is greatly reduced by not having cars in Bayview Village, and by capturing storm water before it can flow into city storm drains. Off-site water is used only for initially establishing plants; moisture sensors trigger water from storm retention ponds for most watering. Water not used on the surface replenishes natural aquifers.
Drought-resistant plants, such as bushy verbena, manzanita, buckwheat, blue fescue, rushes, and sage thrive at Bayview Village. No oil-derived pesticides or fertilizers are used except possibly for some small, showy plants at the office and Village Square. It is important to conserve the limited soil on the site for use in landscaped areas. The natural landscaping will attract bees, moths, butterflies, and birds, making walking through Bayview Village a veritable Nature Study.
