Statement of Work:

Vandenberg SFB Population Study

This Statement of Work (SOW) outlines the requirements for updating 10-year-old population data to determine the current daytime and nighttime population within a defined radius of the south base of Vandenberg Space Force Base (VSFB). This updated data is crucial for flight safety analysis.

The primary objective of this study is to accurately estimate the current daytime (5am-5pm), evening (5pm-11pm), and daytime (11pm-5am) population, accounting for seasonal variations, within the established study area. The Area of Responsibility (AOR) overlays small portions of tracts 9802 and 31.02, and includes areas encompassing Hillside Ranch, Dangermond Preserve, and elements of Miguelito Canyon (see AOR Maps). This includes differentiating between residential, commercial, and other land uses. The updated data will be used for launch flight safety analysis.

The Contractor shall provide all labor, equipment, supplies, materials, transportation, and supervision.

Standard Hours of Operations are 08:00-16:30 PST, Mon-Fri; however, completion of the study may require performing Non-Standard Hours of Operations 16:31 to 07:59 PST, Mon-Fri, some weekends, and some holidays.

The Contractor shall perform the following tasks:

Review Existing Study: Thoroughly review the existing 10-year-old population data and understand the previous methodology, data sources, and findings.

Define Study Area with SLD 30 Safety: Confirm the geographical boundaries of the study area, ensuring consistency with the previous population data unless otherwise directed by the Client.

Data Collection and Analysis: Utilize a combination of methodologies to update the population data, accounting for diurnal and seasonal variations:

Analyze recent census data and other publicly available demographic information.

Leverage satellite imagery and remote sensing techniques to identify changes in land use and development patterns. With a preference for recording data for each building/site separately.

Incorporate publicly available data on local businesses, employment, and residential occupancy.

Seasonal Variation Analysis: Analyze data to estimate population fluctuations throughout the year, considering tourism, seasonal employment, and other relevant factors.

Day/Night Variation Analysis: Employ appropriate methods to differentiate between daytime and nighttime populations, considering commuting patterns, business operations, and residential occupancy.

Flight Safety Integration: Ensure the updated population data is formatted and presented in a manner suitable for integration into flight safety analysis models.

Reporting: Prepare a comprehensive report documenting the methodology, data sources, analysis, and findings. The report should include:

Clear maps of the study area depicting population distribution and density.

Tables and charts presenting the updated population data, including seasonal and day/night variations.

Comparison with the previous data, highlighting key changes and trends.

Discussion of limitations and potential sources of error.
