Catch the Rain By Slowing and Storing It

If rain gutters are installed on your house, water will be directed into downspouts, where it can move with great force and speed. This is especially true in a large storm. Instead of allowing downspouts to discharge directly on hard surfaces like a driveway, path, or patio, think about ways to redirect downspout water into vegetated landscape areas. 

One option is to replace downspouts with rainchains to slow down the water so it can be more easily absorbed when it reaches your landscape areas. Add a rain barrel or cistern at the bottom of downspouts or rainchains and let it overflow into the garden. 

If rain gutters are not installed, water shears off roof surfaces and can cause erosion damage. Areas under the eaves may be covered in permeable groundcovers such as pea gravel, mulch, or rocks to reduce the compacting force of water falling on bare soil. Spreading fresh leaf and wood chip mulch throughout the garden will slow down water. Healthy soil can withstand even the strongest rain.   

Ways of storing rainfall  

Rainwater can also be harvested and stored. Storage vessels include rain barrels and cisterns directly connected to downspouts  

Stored water can be released gradually into the landscaping between winter rainstorms, building up the soil sponge and ensuring that native plants get adequate water during the winter months when they need it most. If you need water in the summer and capture enough of it during the winter, you may be able to use your cistern water for irrigation  

Both rain barrels and aboveground cisterns can be relatively inexpensive to purchase and easy to install. Mosquitos are kept out using screens. With minimum maintenance and common sense, the water can be kept safe. If you plan to store rainwater, make sure the “first flush” is diverted directly into the landscaping before capturing the rainfall that follows.  

Properly placed trees also are excellent landscaping features to help capture rainfall, allowing it to be released slowly over time into the soil.

Local Agencies Respond Faster Than Federal Agencies To Request For Public Records

While some public agencies in San Diego County delay or outright fail to turn over public documents, a San Diego Union-Tribune review found they’re far more responsive than federal agencies, which have more freedom to delay or under weaker public records laws. In January U-T Watchdog sought six months’ worth of email records that contained four phrases — “off the record,” “off record,” “on background” and “deep background” — from nearly 100 public agencies. The phrases refer to reporters’ and sources’ agreements to confidentially share information.
