Question #1: Can you provide a bit more detail about the topographical map desired for the project? Such as the extent of the land included in it, an approximate numerical of labels and callouts (the lake itself, park entrances, a legend, etc.).

Clarification: The map should mirror the park’s boundaries but can include some additional area if needed to make the structure a convenient shape. Park boundaries should be delineated on the Topo map. The map should focus on the geography of the area, emphasizing the teachable features (desert mountains, the role of weather and natural forces on the land, our relationship with neighboring land agencies like USFS, etc.). The emphasis should be interpretive information. Major trails and landmarks can be marked, such as the Nature Center, campgrounds, and PCT trail. Amenities are optional, such as the boat launch and parking lots. I have attached the park brochure, which includes the park map.

H igh in the heart of the San Bernardino National Forest, Silverwood Lake State Recreation Area captures the eye and the imagination with vistas of snow-capped mountain peaks reflected on the lake.

The lake was formed by the 249-foot Cedar Springs Dam, which holds back the waters of the west fork of the Mojave River as it passes through the San Bernardino Mountains.

Warm, dry breezes prevail during summer — with high temperatures averaging between 90 and 100 degrees from June to September. From December through March, rainy winter temperatures vary from the low 30s to the low 60s.

NATIVE PEOPLE

For more than 2,500 years, the Serrano (Spanish for “mountain people”) Indians occupied the San Bernardino Mountains and extended into the desert far to the northeast, north, and northwest as far as the Southern Sierra Mountains, Barstow region, and Twentynine Palms.

Alongside rivers and streams, the Serrano lived in settlements of 10 to 20 dwellings.

Their circular-shaped homes were usually made of willow frames covered in brush or tule reeds and tied with various fibers or rawhide. Several Serrano settlements, including Yucaipa and Cucamonga, have modern towns that bear their names.

The Serrano used ritual, including songs and storytelling, to pass along knowledge necessary to maintain the Earth’s natural order. Skilled artisans, the Serrano were known for their beautiful woven baskets.

The Serrano traded with the Mojave tribe to the east and Tongva (Gabrieliño) to the west for goods they could not produce themselves.

The stable lives and traditions of the Serrano changed drastically around 1790, when they were drawn into the San Gabriel Mission. Hard labor and European diseases took their toll. By the early 20th century, the area’s estimated 1,500 Serrano people had dwindled to 119. Today some Serrano descendants live on or near the San Manuel and Morongo Indian Reservations.

THE STATE WATER PROjECT Silverwood Lake was named for W. E. “Ted” Silverwood, a Riverside County resident.

Silverwood’s support for the State Water Project— and his unceasing work for water and soil conservation— helped to bring water to Southern California.

Supplying water and power for California’s agriculture, cities, and industry, the

Water Project also provides flood control, recreation, and protection and enhancement of fish and wildlife. The lake waters begin in California’s upper Feather River Basin as rain or snowmelt. From the water storage facility at Lake Oroville, the water is released in regulated amounts, flowing down the Feather and Sacramento Rivers to the Sacramento- San Joaquin Delta and into the 444-mile California Aqueduct.

The water moves south to the foot of the Tehachapi Mountains. It enters Southern California on the south side of the Tehachapis, then splits into the west branch serving the Los Angeles Basin and Ventura County’s coastal areas, and the east branch, which serves the Antelope Valley and San Bernardino, Riverside, Orange, and San Diego Counties. In the Antelope Valley, the water level is pumped to a height of 3,480 feet above sea level, then downhill, under the Mojave River and Highway 173, and finally, it reaches Silverwood Lake.

From the intake towers at the south end of Silverwood Lake, the water continues south, where it plunges 1,600 feet to spin the turbines that generate electricity. Some of the water goes to contracting agencies, while the rest flows on to Lake Perris, the southern terminus of the aqueduct.

WILdLIFE ANd HABITATS California mule deer are often seen in early morning and sometimes in the evenings.

Night predators such as gray foxes, coyotes, and (rarely) mountain lions use the darkness to hunt such small mammals as rabbits, jackrabbits, squirrels, ringtails, chipmunks, and wood rats.

Black bears, bobcats, and golden beavers may be seen along the Mojave River. In winter, bald eagles glide silently above the lake, fishing for their next meal. Water-oriented birds — great blue herons, snowy egrets, avocets, western grebes, loons, Canada geese, mergansers, and several varieties of ducks — are plentiful. Around Sawpit Canyon, birds of prey include red-tailed hawks, Cooper’s hawks, ospreys, and roadrunners. This area is also home to Clark’s nutcrackers, Steller’s and scrub jays, rock wrens, and mountain bluebirds.

Great blue heron

Silverwood Lake habitats include ponderosa pine, incense cedar, white fir, and black oak. Along the shore, chamise, live oak, manzanita, ceanothus, and mountain mahogany grow.

Alders, willows, and sycamores are found along streams.

Silverwood Lake offers 976 acres of water recreation.

Question #2: Is the payment and performance bond to be in the amount of the bid, or the full budget amount as stated in the RFP?

Clarification: Payment and Performance bond will be in the amount of the bid only.

Question #3: The RFP states "Contractor will review draft content provided by State Parks staff..." Will this be in the form of actual exhibit text, even if it is considered preliminary, or will it be in a bullet point or outline form that the contractor will need to adapt to final test form? Will the State Parks provide this draft in both required languages?

Clarification: It will be provided by park staff in outline or bullet point form. Draft exhibit text will be developed from that, which will be finalized through collaboration between park staff and contractor. Preliminary text will be provided to contractor in English. Once exhibit text is finalized, State Parks can provide translations.

Question #4: I believe that the current video presentation within the visitor center building includes a descriptive audio track in the form of subtitles. And there is braille on the push button panel. Also, if I'm not mistaken, there are headphone devices available to guests that might need such an audio track for the exhibits. Will such ADA compliant requirements be needed here? Who would provide the audio track? Would it also be in both English and Spanish?

Clarification: Yes, those elements are in the video inside the Nature Center. If there is video or audio in the exterior exhibits, it will also need to be ADA compliant. The challenge with outdoor exhibits is protection from weather, vandalism, and other damage, so any video or audio elements, and their ADA elements will need to be developed with that in mind. Any audio track would need to be provided by the contractor, in consultation with State Park staff. Spanish track would be appreciated as it would allow both interior and exterior exhibits to be consistently bilingual. But this could be in the form of closed captioning.

Question #5: Who will verify overall ADA compliance. Does the State Parks have an ADA compliance person that will review the designs as they are developed?

Clarification: State Parks Accessibility Division ( https://www.parks.ca.gov/?page_id=21944 ) is the final check-off for the ADA compliance. There are some accessibility guidelines in the appendix for the Interpretive Project Plan that was distributed at the contractor walkthrough, but the more complete set is in the California State Parks Accessibility Guidelines (2015 edition) which can be found as a PDF at https://www.parks.ca.gov/pages/21944/files/2015_CSP_Accessibility_Guidelines(v3)(UNSECURED).pdf (It is also a link on the main Accessibility page above. Any questions would be referred by park staff to the Accessibility division for clarification and guidance.
