San Diego River floods during heavy rain.

It rained very heavily in San Diego today. I heard that some coastal areas received up to four inches of rain. That’s a staggering amount of water in less than 24 hours for our naturally arid climate.

Not surprisingly, many parts of the city flooded. A couple of highways partially closed. All three trolley lines had service disruptions.

Severe flooding often occurs in Mission Valley as the San Diego River rapidly swells. As you can see in my photos, that happened again.

Late this afternoon I observed two cars half underwater where Mission Center Road crosses the San Diego River. I hope those drivers are okay.

Holding my umbrella, I then walked along the leaf-strewn pathway beside the swollen river.

The above sign west of Mission Center Road explains the San Diego River’s peculiarities, and why periodic flooding is actually helpful:

A River in Flood

Under historical conditions, the seasonal variation in San Diego’s rainfall creates strong fluctuation in the amount of water flowing within the San Diego River. The low rainfall and the geologic composition allowed for the river to run below ground during much of the year; this lead to the River’s nickname, the Upside Down River.

Habitats and vegetation adapted to flooding in the winter and subsurface flow in the summer. Flooding helped restore the natural river bottom, flushed out debris, created new sand bars and kept the river healthy.

Large flooding events were common and are natural along the river course. Over time, with the construction of regional reservoirs, El Capitan in 1934 and San Vicente in 1943, these large flooding event have been reduced and flows constrained.

Every year we’re reminded: Avoid driving in flooded areas!

Historic U.S. Route 101 signs debut in South Bay!

Thirteen new Historic California US 101 Route Signs have debuted in San Ysidro and Chula Vista, marking where the legendary highway once ran through the South Bay. The signs recall a time when motorists relied on old Highway 101 to travel from San Diego down to Mexico.

The signs, recently installed by the City of San Diego and Chula Vista, are part of a project undertaken by the South Bay Historical Society, led by Jack Gechter. Seven additional signs have been created for National City. Hopefully those will debut soon, too!

Here is Jack’s Facebook page with a post that describes exactly where these new Historic California US 101 Route Signs have been placed.

I walked along Beyer Boulevard in San Ysidro this morning to capture a few photographs. Had I continued north into Chula Vista, where Beyer turns into Broadway, I would have seen more of these awesome new signs!

Here’s a blog post from last summer where I share more details about the project. You’ll find links to maps depicting where U.S. Route 101 once ran south of downtown San Diego.

History at Mission Valley river park.

History is being made in Mission Valley. Two massive projects are being developed along the San Diego River: SDSU Mission Valley and Riverwalk San Diego.

The river park at SDSU Mission Valley is mostly complete, and large areas are now accessible to the public during its soft opening.

I walked around the river park the other day and found a number of fascinating information signs. One shows birds that might be found along the San Diego River. Another concerns stormwater management and the creation of bioretention basins. The largest such basin is located near the Stadium trolley station.

The signs that interested me most concern the history of Mission Valley and the San Diego River.

I took photos of several signs, which you can enlarge for easier reading…

The Native American Kumeyaay historically used plants along the river for food, tools and construction materials. They sustainably managed the land. Before World War II and the subsequent boom in urban development, Mission Valley was largely farmland. At one point there were 20 dairy farms in Mission Valley. Several Japanese American families operated vegetable farms.

Early 1900s postcards of Mission Valley show large areas of green farmland on either side of the San Diego River.

New plants for the new river park at SDSU Mission Valley.

The San Diego River begins in the Cuyamaca Mountains and flows west to the Pacific Ocean. It is the source of important biodiversity. In 1971, plans to replace the sometimes flooding river with a concrete channel were thwarted by intense public opposition. The vision of a more natural San Diego River, with innovative safeguards against flooding, would eventually prevail.

The Kumeyaay were the first people to live in this region. This sign explains they understood the importance of caring for the land, water, flora and fauna that are all a part of this intricate ecological system that relates and sustains all life in balance and harmony. A map of Kumeyaay territory includes San Diego County and the northern portion of Baja California.

Adam T. Gastelum street sign in Barrio Logan.

Have you wondered about an Honorary Adam T. Gastelum street sign in Barrio Logan? I recently noticed it on Evans Street, at the intersection of Logan Avenue.

Curious to learn more about Adam T. Gastelum, I did a little searching.

An obituary summarizes several accomplishments of the proud Hispanic American Army veteran. He is credited with helping to found nearby San Diego VFW Post 7420. It also explains: Adam joined the Army to serve in World War II. His campaign battles included Normandy, Northern Ardennes, Rhineland and Central Europe.

I also discovered that on October 22, 2018, a San Diego City Council Resolution designated the 900 block of Evans Street between the intersection of Logan Avenue and National Avenue to be known as Adam Trejo Gastellum Street.

Many in San Diego appreciate his service.

Wetland restored at Cottonwood Creek in Encinitas.

Cottonwood Creek Park in Encinitas is a place to play, picnic, relax and enjoy nature. A beautiful walkway crosses over Cottonwood Creek and leads to leafy overlooks.

At one overlook, a sign lures inquisitive eyes. It describes how the nearby wetland was re-created, where for many years the water had been piped underground directly to the portion of the creek that lies west of the Pacific Coast Highway. The park and its restored wetland lie immediately east of Vulcan Avenue (a short distance east of Coast Highway 101).

The benefit of water filtration by plants (such as bulrushes and sedges) and plant litter (decomposing vegetation) is explained. Water that eventually flows into the ocean at Moonlight Beach is naturally cleaned of contaminants like heavy metals, nitrates and phosphorus.

The reclaimed riparian habitat also supports many native species. Trees, frogs and butterflies that benefit are depicted on a second sign.

To read more, enlarge the two sign images.

New sign in San Diego welcomes to Cortez.

Walking down from the top of Cortez Hill a couple days ago, I noticed a brand new landmark sign that welcomes people to the neighborhood!

The metal, ribbon-like sculpture greets those driving into downtown San Diego via California State Route 163 and Ash Street. It’s located at the corner of Eighth Avenue and Ash Street, near the southeast corner of the historic El Cortez building.

(Did you know the El Cortez had the world’s first outdoor glass elevator? See photos and a video by clicking here!)

Signs of Halloween’s approach in San Diego!

Spider webs, skeletons, monsters, pumpkins and jack-o’-lanterns!

Signs have popped up around San Diego indicating Halloween is around the corner!

I took these photos during a very long walk today. I wandered through downtown, Little Italy, Old Town and Bay Park…

A community pumpkin patch in Waterfront Park is readied by Parks and Recreation.

Sign promotes special event in Little Italy: Trick or Treat on India Street!

These horrific creatures appear a bit sleepy. I spotted them inside a window of the San Diego Visitor Information Center near Broadway Pier.

Yes! Halloween lights are right here. Get your black lights, fog machines and mirror balls!

Will the firefighters at Bayside Fire Station No. 2 use their ladder to save this dangling skeleton?

Exhibit for San Diego City Clerk’s Archives Month!

A great exhibit is now open to the public inside the lobby of downtown San Diego’s City Administration Building. The San Diego City Clerk is celebrating its 5th Annual Archives Month with displays concerning our city’s historic 1935-36 California Pacific International Exposition in Balboa Park!

Step into the City Administration Building in the next few days and you’ll discover old photographs and documents concerning the exposition, and even the big coin you see above!

This original coin, inscribed Welcome To America’s Exposition, was actually the welcome sign for San Diego’s second world’s fair, which followed the 1915-16 Panama-California Exposition, also held in Balboa Park.

The above 1935-36 California Pacific International Exposition Sign was donated to the City Clerk Archives for safekeeping.

Here’s a photo of someone posing with the original sign!

There are many fascinating images on display, including photos of American presidents, dignitaries and celebrities who visited the expo almost a century ago. You also have an opportunity to take a selfie with a replica of the coin that is light enough to hold above your head!

Can’t make it downtown? View archived photographs, ephemera and city documents that concern the 1935-36 California Pacific International Exposition by clicking here!

This fascinating historical exhibit will be on display in the City Administration Building lobby from October 2nd through October 16th, so check it out if you can!

A short walk at Moonlight Beach Overlook.

There’s more than a beautiful view of the Pacific Ocean at the Moonlight Beach Overlook in Encinitas. There are a few bits of art, too!

Two trashcans are decorated with colorful tiles painted by youth.

The parklike Moonlight Beach Overlook isn’t large, but it’s a great place to relax, gaze down at the beach below, or perhaps enjoy a picnic on the grass.

The following overlook sign can be spotted just south of the main Moonlight Beach parking lot.

San Diego River restoration near Fashion Valley.

Nearly 5 acres of San Diego River habitat in Mission Valley will be undergoing restoration through 2024. I saw this sign while walking down the San Diego River Trail this afternoon.

Invasive plants will be removed in a stretch north of the river, south of Fashion Valley. According to the sign, non-native species that will removed include the Brazilian pepper tree, Canary Island date palm, Mexican fan palm, eucalyptus and pampas grass.

This is a project of the San Diego River Park Foundation, Urban Corps of San Diego County, and the Fashion Valley mall.

Learn more about this and other river projects, and possibly help out as a volunteer, by clicking here!
