Sumner Hill today
Sumner Hill is built out: the subdivision map was recorded in 1985, all 49 lots were sold by late 1989, and no new lots have been documented since. You reach it through a passcode gate on Killarney Drive off Road 204. A second, private gate on Killkelly Road leads down to the river and is for HOA members only.
The neighborhood around it is changing. Tesoro Viejo has more than 1,000 of up to 5,190 planned homes, with future villages such as The Vistas and River's Bend still to come. Yosemite Travel Center, with a market, a 76 station, a car wash and a Jamba Juice, opened at SR 41 and Avenue 15 in July 2026, and RiverStone, to the south, has a Raley's O-N-E Market lined up.
SR 41 is being widened to 4 lanes from Avenue 10 to Avenue 15 between May 2026 and May 2028, so expect construction traffic on the drive to Fresno. The nearest fire station is Madera County Fire Station No. 7 in the Tesoro Viejo Town Center.

What the homes are like
- Lots
-
49 lots, generally about 1.5 to 6 acres; listed examples include 2.27 and 2.46 acres.
- Age and style
-
Custom estate homes built from the late 1980s on, with listed examples from 1989 and 2016. There is no production builder; sales are resales and the occasional custom build.
- Gate and HOA
-
The gate and perimeter fence were a condition of the county's approval. The roads are private: the county gave up its interest in them in the 1990s, and a 2012 appeals ruling found that lot owners own most of Killarney Drive and parts of Killkelly Road. The homeowners association maintains the gate and fence; dues vary, so check each listing. No Mello-Roos is documented.
- Water
-
Our sources disagree on how homes get water, so confirm the water source and any shared-well agreement for each property.

A ranch bluff, a gate and a river case
Sumner Hill sits on the eastern part of the old Peck Ranch, which Sumner-Peck Ranch, Inc. held as more than 1,500 acres between SR 41 and the river. Madera County approved the subdivision in 1983 on the condition that it install a security gate and perimeter fence. It opened in October 1985, and the county later gave up its interest in the roads, which are private.
When a McCaffrey-led company bought the rest of Peck Ranch in 2004 for what became Tesoro Viejo, a long dispute over the Killkelly Road river access followed. A 2008 trial court decision confirmed Sumner Hill as a private gated subdivision with exclusive river access, and in 2012 the 5th District Court of Appeal largely upheld the homeowners' rights.
- 1983Madera County approves the subdivision with a required gate and perimeter fence.
- 1985The amended final map is recorded, and the community opens in October.
- 1989All lots are sold by late in the year.
- 2004The rest of Peck Ranch is sold for what becomes Tesoro Viejo.
- 2006The HOA and lot owners sue the developer over river access.
- 2008A trial court decision on July 21 confirms the private gated status and exclusive river access.
- 2009A jury awards the homeowners $3.2 million in punitive damages.
- 2012The Court of Appeal largely upholds the homeowners' rights in May.
Stories from the bluff
-
A case in the law books
The river-access fight is cited in legal writing. In it, the appeals court noted that California has protected public access to navigable waters since 1879.
-
The view
From the bluff you can see Friant Dam, Lost Lake, the San Joaquin River and the Sierra foothills. Deer, geese, raccoons, skunks and coyotes are reported in the area.

Not Sumner Peck Ranch
The Sumner Peck Ranch across the river in Friant is a separate 76-acre farm and winery. The San Joaquin River Parkway Trust bought it in December 2020 and renamed it Running River Ranch in 2026.
