Searching for San Pascual…

Over the past few weeks, I’ve been dialoguing via email with a fellow creekfreak about the location of Arroyo San Pascual, which was/is in the Pasadena/San Marino/Alhambra area.  I thought I’d post the maps that explain this location so that everyone can enjoy the info.  For those wishing to cut to the chase – Arroyo San Pascual is the westernmost of the creeks, joining with Mill Creek to create Mission Creek  (aka, I believe, Alhambra Wash) further downstream.  To the east are smaller creeks, including one that once fed the pond (Kewen Lake) that has since been filled for, um, lawn, at Lacy Park in San Marino.  Jane Tsong covered the topic of the arroyos and fascinating geology of this area in depth (here 1, 2) – so I’m going to stick to the maps.

To the left, a federal survey from 1870 which actually gave us some creek names.  (when I have a moment I’ll scan and post the entire survey so you can see the rest)  To the right, a screen shot of the creek layer I created several years back in GIS, which when imported as kmz files in GoogleEarth has a standing flaw of being offset slightly.  The discerning eye can see echoes of the historical streams in the treelines, shadows of terrain, (in)convenient siting of ball fields… correlation of course not being causation.  The arrows are meant to call that out for you, imagine those blue lines shifted slightly to the left.  Happy creekfreaking, if you get inspired to tour to the topography, let us know what you find out!

Creek Freaks tour historic San Marino canyon creeks

The four L.A. Creek Freak blog writers: Jessica Hall, Joe Linton, Joshua Link, and Jane Tsong.

Earlier this week was a rare coming together of all four L.A. Creek Freak authors: Jessica Hall, Joshua Link, Jane Tsong, and Joe Linton. We all know each other, and run into each other at various functions, and keep in contact… but I think it may be the first time that all four of us spent good creek-freek time together. We’ve all contributed to this post – Joe did the compilation, so I’ve tried to weave and acknowledge… and any errors are mine.

The occasion was a private tour of some of the historic creeks and canyons in the city of San Marino, and the adjacent southern border of the city of Pasadena. Our expert guide was Alan Jutzi, Avery Chief Curator of Rare Books at the Huntington Library, Art Collections and Botanical Gardens. Alan is the curator for the Huntington’s upcoming show Water Began It All, which Jane is designing. She wrote about here earlier. Water Began It All is open weekends November 19th, 2011, through February 18th, 2012 at the Flora-Legium in the Botanical Center. As Jane described, the show features the work of Michael Hart, who’s an artist but better known for running the Sunny Slope Water Company, located in Pasadena and the San Gabriel Valley. Hart is responsible for using existing landscape and historical documents to map out these canyons, creeks, zanjas and more. Michael Hart’s prints, including exquisitely detailed maps (much better than the roughly mapped google map below) will be available for purchase in the Huntington bookstore.

Hart’s work was reviewed in last week’s L.A. Times Lost L.A. column by Sam Watters. The article is a good creek-freak read, and includes Hart’s piece, Old Mill in San Marino, a location that  featured prominently in the tour this post describes below.

Act now to save Arcadia's threatened oaks! Photo by ecotonestudios

RECENT NEWS:

> If you haven’t read Josh’s article yesterday about the urgency of action to prevent the county’s astonishingly wrong-headed plans for burying Arcadia’s oak woodlands – read it and take action! Demolition is scheduled to begin next week. Here’s a set of links of  yesterday’s blogger solidarity day post to save this irreplaceable site: Altadena Hiker, ArcadiaPatchBallona BlogBipedality, Breathing TreatmentChance of Rain, Echoes, Greensward CivitasL.A.

> Oiled Wildlife Care Network reports an oil spill in the Dominguez Channel on December 22nd 2010. Their team “recovered three oiled birds:  one Pied-billed grebe, which died, and two American Coots.”  As of January 4th, OWCN reports that  “no responsible party has been identified, and the source of the spill remains unknown.” Full story at link.

> ArroyoLover reports on the drawbacks (pun intended) of new archery range fencing proposed for Pasadena’s Lower Arroyo Seco Nature Park.

> L.A.’s Daily News reports a Shadow Hills incident where a “car raced downhill, bouncing over speed bumps before brushing by horse and rider, spooking them to the curb. [The horse was] injured [and ultimately perished] when she became trapped in a storm drain debris screen[...]. The driver did not stop.” Interestingly the article calls for changes to the storm drain trash grates, but seems to let the criminal speeding driver off the hook. Full story at link.

> If you think L.A.’s La Niña rains were bad, read Circle of Blue‘s reports on disastrous El Niño rains in Colombia and Venezuela.

> The Los Angeles Times has an impressive photo of water churning through the San Gabriel Dam during recent tests. Also at L.A. Times: environmentalists file suit to block Newhall Ranch development imperiling the Santa Clara River. And, further afield, plans for the future health of the Klamath River.

> The Project For Public Spaces has an extensive conference proceedings document that serves as a sort of handbook for waterfront design/place-making. Their top recommendations (as distilled by me) are: multiple destinations, connected by trails for walking and bicycling.

Deciding Hahamongna’s fate. Again.

"The original bridge over the site of the Devil's Gate Dam. As of 1987, there is no longer a reservoir. The site may be seen from Highway 210, north of the Arroyo Seco and south of Jet Propulsion Laboratory." 1920. Source: LAPL, Photo: 00017346

We’ve touched on this before, but today is a day of blogger solidarity to protect Hahamongna in its current state. The Pasadena City Council will meet on Monday, July 12, to vote on whether or not to place soccer fields within this natural park that contains a now rare thing in the greater LA area: oak woodlands and riparian and wetland habitat.

Details for the meeting:

Monday, July 12, 6:30-8:30pm; at 100 North Garfield Avenue, Pasadena, CA

Soccer at Hahamongna?

April 21, 2010 § 3 Comments

Aerial view of Hahamongna. Photo from (and linked to) Arroyo Seco Foundation website.

Once again, active recreation and our dwindling natural resources are being pitted against each other.  This time, it’s at Hahamongna, a basin on the Arroyo Seco next to JPL.  Devil’s Gate Dam holds back the Arroyo’s flows, infiltrating some of them into the Raymond Basin, the aquifer that supplies a lot of Pasadena’s water.  Above ground, wetlands and oak woodlands abound, a rare finger of habitat extending down from the San Gabriel Mountains.

Should soccer be carved out of this? « Read the rest of this entry »

News and Events – 17 February 2010

UPCOMING EVENTS:

>The L.A. County Bicycle Master Plan Bicycle Advisory Committee meets tonight Thursday February 17th at 7pm at the Board Overflow Room at Metro. The county bike plan, which Creek Freak outlined here, includes bike paths along county-maintained rivers, washes and creeks. There’s also a series of ten county bike plan community meetings running February 22nd through March 25th, held in various locations all over the county. For more info on all these, go to the meeting page on the county’s bike plan website.  

County photo of the vacant under-freeway right-of-way along the Arroyo Seco. View is looking northeast toward Avenue 26, with the Arroyo Seco channel just out of the picture to the left. Avenue 26 is across the middle of the image with the Avenue 26 Bridge in middle left. Freeway ramp connecting southbound 110 to northbound 5 is on the right.

>Los Angeles County is proposing a new scope for the funded Arroyo Seco Bike Path project. The new plan is to build the next phase along the southeast bank of the arroyo from Avenue 26 to San Fernando Road. This scales back a proposed ~1.5-mile bike path (from Avenue 43 to Avenue 26) to an ~0.3-mile bike and walk path, but the less ambitious new scope appears more likely to actually get built. The newly proposed stretch would be located in a right-of-way that is currently mostly empty space (below the interchange of the 5 and the 110 freeways) but also includes a portion of a city of L.A. Bureau of Sanitation yard. The county hosts a project meeting tomorrow Thursday February 18th at 6pm at the Los Angeles River Center. Check out the county’s 9-page background report, with photos and a map and L.A. Creek Freak’s earlier article on the conflicts over the earlier proposed bike path(Thanks Arroyo Seco Foundation for posting the county’s documents on-line.)

>Same night as the Arroyo Seco meeting, the city of Glendale hosts a public input meeting for its Glendale Narrows River Walk project. It’s Thursday February 18th at 7pm at the Pacific Community Center.

>C.I.C.L.E.’s creek freak bike ride is this Saturday February 20th, departing 12:30pm from the River Center. Rain cancels, and some is predicted for early Saturday – check the site that morning around 9am to confirm that the ride is on.

>State Assembly Speaker Karen Bass hosts a Ballona Creek clean-up event on Sunday February 21st at 10am at Overland Avenue.

> The city of Pasadena Bicycle Master Plan is also underway. The current draft  proposes bike paths along the Arroyo Seco (near Jet Propulsion Laboratory) and along Eaton Wash (from Eaton Canyon Nature Center to the 210 Freeway.) Pasadena will hold a public input meeting on their draft plan on Tuesday February 23rd at 6:30pm at City Council Chambers.

Grading and Draining: the transformation of the Shorb Ranch

The property we know as the Huntington Library, Art Collections, and Botanical Gardens, was once part of the famed ranch of J. De Barth Shorb, named San Marino. We are fortunate that relatively detailed documentation of the property has been preserved, giving us an intimate view of shifts in land use during the intervening century. « Read the rest of this entry »
