CALIFORNIA SUPPLEMENTAL EXAM - LANDSCAPE
ARCHITECTURE (ENVIRONMENTAL REGULATIONS) 2025| 130
QUESTIONS WITH ACCURATE SOLUTIONS
1. Describe how environmental changes can affect oak trees and lead to
oak root fungus.
Oak trees thrive under all environmental conditions, regardless of
changes.
Sudden changes in the environment can stress oak trees, making
them more susceptible to oak root fungus, which can lead to
symptoms like dieback and premature leaf drop.
Environmental changes only affect the soil quality, not the trees
themselves.
Environmental changes have no impact on oak trees and their
health.
2. Describe the significance of Categorical Exemptions in the context of
environmental regulations in California.
Categorical Exemptions allow certain projects to proceed
without extensive environmental review, streamlining the
approval process for low-impact projects.
Categorical Exemptions are only applicable to projects funded by
state agencies.
Categorical Exemptions require all projects to undergo a detailed
environmental impact assessment.
Categorical Exemptions are used to delay project approvals for
environmental assessments.
3. If a new greywater disposal field is being designed, which of the
following considerations should be prioritized to ensure effective
filtration?
,Using only one type of filter material to simplify construction.
, Eliminating any top layer to allow for faster drainage.
Incorporating multiple layers of filter materials, including stone,
gravel, and additional top layers like straw.
Designing the field to be completely sealed to prevent any water
loss.
4. In a scenario where a city needs to increase its water pressure for
firefighting purposes, which method would be most effective?
Reducing water flow to increase pressure
Installing larger diameter pipes
Using chemical additives to increase pressure
Elevating water in tanks, towers & reservoirs
5. What does the ETWU formula stand for in environmental regulations
related to irrigation?
ETWU stands for Estimated Total Water Utility.
ETWU stands for Effective Total Water Use.
ETWU stands for Estimated Total Water Use.
ETWU stands for Environmental Total Water Usage.
6. Describe the significance of the exceptions outlined in MWELO for
certain types of landscapes and projects.
The exceptions apply only to new construction projects and not
to existing landscapes.
The exceptions indicate that all landscapes must adhere to the
same irrigation standards regardless of their type.
The exceptions in MWELO allow for flexibility in managing water
use for landscapes that have historical, ecological, or cultural
, importance, ensuring they can be maintained without the
constraints of permanent irrigation.
The exceptions are designed to eliminate the need for any form of
irrigation in California.
7. The federal agency in charge of disaster planning is:
Office of Civil Defense
Department of the Interior
Department of the Army
Federal Emergency Management Agency
8. What is the amount of pressure that is exerted on the surface of water in
a container for every foot of height that the water rises?
Density pressure
Static pressure
Head pressure
Draft pressure
9. What is the primary mission of the United States Fish & Wildlife Service
(USFWS)?
To enforce environmental protection laws.
To regulate outdoor lighting and irrigation systems.
To manage disaster response and recovery efforts.
To conserve and protect fish, wildlife, plants, and their habitats.
10. If a new urban development project qualifies for a Categorical
Exemption under CEQA, what implications does this have for the
environmental review process?
