LEGIBILITY ASSESSMENT REPORT
Frederick County Ordinance No. 26-01-001
Comprehensive Zoning for the Critical Digital Infrastructure Overlay Zone
(An Element of the Livable Frederick Comprehensive Plan, Effective January 20, 2026)
Analysis of Accessibility and Readability for Adults Aged 45 Years and Older
Prepared: June 02, 2026
EXECUTIVE SUMMARY
This report evaluates the legibility from a visual analysis of the attached Frederick County zoning ordinance document for the general adult population aged 45 years and older, with particular attention to senior citizens (65+). The document is a single-page, image-based PDF presenting the adopting ordinance text alongside two map illustrations of the Critical Digital Infrastructure Overlay Zone.
Key Findings: The document presents moderate to significant legibility challenges for readers aged 45 and older. Primary impairments stem from: (1) small body text size (estimated 9–11 pt serif font, below recommended 14–18 pt for accessible print); (2) photographic capture reducing sharpness and contrast; (3) dense paragraph layout with limited white space; and (4) map details and legends that are difficult to decipher without magnification, especially for individuals with age-related declines in visual acuity, contrast sensitivity, and near-focus ability (presbyopia). A substantial portion of the 45–64 age group and the majority of adults 65+ are likely to experience eye strain, require reading aids, or need assistance to fully read and interpret the legal text and maps.
1. DOCUMENT DESCRIPTION
The document consists of one page containing:
· Left side (stacked text boxes): Legal ordinance text including title, multiple WHEREAS clauses, enacting language, and signatures. Vertical rotated text appears in the far-left margin.
· Right side (stacked maps): Upper map showing the overlay zone boundary (black shading) with legend; lower map providing additional geographic context (possibly parcel or infrastructure layers) with its own legend.
· Format: Image-based (scanned/photographed) PDF with no selectable or searchable text layer. The provided view is a photograph of the physical page, introducing minor shadows, uneven lighting, and reduced effective resolution.
2. METHODOLOGY
Assessment was performed via direct visual inspection of the rendered page at high resolution, combined with established accessibility guidelines and clinical knowledge of age-related visual changes. No text extraction was possible due to the image-only nature of the PDF. Font sizes were estimated by comparison to standard print references and visual density. Recommendations draw from sources including American Council of the Blind Large Print Guidelines, Section 508/WCAG principles adapted for print, cartographic legibility standards (Esri), and peer-reviewed findings on older-adult font preferences and visual function decline.
3. DETAILED LEGIBILITY FINDINGS
3.1 Text Characteristics and Font Size
The body text in the WHEREAS and enacting sections appears to be set in a serif typeface (likely Times or similar) at an estimated 9–11 point size. Headings and the main title are larger (approximately 12–14 pt) and bolder. The vertical margin text is significantly smaller and narrower.
· Below accessibility thresholds: Multiple guidelines recommend a minimum of 14 pt (ideally 16–18 pt) for body text in documents intended for older adults or large-print versions. Standard 10–11 pt legal text is already marginal for many readers over 45.
· Serif vs. sans-serif: While serif fonts can aid reading in long print passages for some, at small sizes and reduced contrast they can appear less crisp to aging eyes compared to clean sans-serif faces (Arial, Calibri, Verdana).
· Density: Long, unbroken paragraphs increase line-tracking difficulty, especially when combined with presbyopia (requiring constant refocusing).
3.2 Contrast, Sharpness, and Capture Quality
The photographic capture of the physical page results in reduced effective contrast and sharpness compared to a native digital or high-quality flatbed scan. Some areas appear slightly soft or grayish. Age-related reduction in contrast sensitivity (common after age 50–60 and exacerbated by cataracts or ocular surface changes) makes it harder to distinguish fine text strokes or subtle map boundaries. High-contrast black-on-white is used, which is appropriate, but the capture quality undermines this advantage.
3.3 Map Legibility and Decipherability
Upper Map: Relatively clear. The solid black overlay shading provides good figure-ground separation. Legend text is small but mostly legible with magnification. Major roads and boundaries are distinguishable.
Lower Map: More challenging. It contains finer lines, multiple overlapping elements, and smaller legend/type. Distinguishing specific parcels, infrastructure details, or exact zone boundaries is difficult without close inspection or magnification. Color/shading differentiation may be harder for readers with reduced color discrimination or contrast sensitivity.
General Map Issues for Older Adults: Cartographic research indicates legend text should ideally be 12–14 pt; symbols no smaller than ~2/3 of text size. Fine details and small labels on the lower map fall below comfortable thresholds for many seniors and will cause frustration or errors in interpretation.
3.4 Layout, White Space, and Visual Flow
The layout places dense text boxes on the left and maps on the right in a stacked configuration with minimal margins between elements. This creates a cramped appearance with limited breathing room. Consequences for 45+ readers include:
· Increased visual fatigue and cognitive load when switching between text and maps.
· Difficulty maintaining place while reading long legal clauses (no generous leading or paragraph spacing).
· The vertical sidebar text is awkward to read and easily overlooked or strained.
· Overall page feels busy; older adults often benefit from more generous white space, larger margins, and clearer visual hierarchy to reduce overwhelm.
· Single-page dense format offers no natural breaks for rest or section navigation.
4. IMPACT ON ADULTS AGED 45 YEARS AND OLDER
4.1 Age-Related Visual Changes Relevant to Document Reading
Presbyopia (loss of near accommodation) typically begins in the early-to-mid 40s and progresses until the mid-60s. By age 45–50, many individuals require reading glasses or bifocals for comfortable near work. Small print (under ~12–14 pt) forces greater effort, arm’s-length holding, or reliance on magnification. Reduced contrast sensitivity and decreased visual acuity for fine detail become more pronounced after 55–60, making thin lines, small legend text, and any softness from photographic capture problematic. Additional factors include slower dark adaptation, increased glare sensitivity, and potential presence of cataracts or dry eye.
4.2 Estimated Impact by Age Cohort
| Age Group | Estimated % Experiencing Difficulty | Primary Impairments & Likely Experience |
| 45–54 years | 25–40% | Many beginning to notice presbyopia. Small dense text causes eye strain, slower reading, need for readers or brighter light. Maps mostly decipherable with effort but lower map details tiring. |
| 55–64 years | 45–65% | Presbyopia well-established for most. Reduced contrast sensitivity common. Significant portion will find full text reading fatiguing without aids; map interpretation (esp. lower map) requires magnification or assistance for precise work. |
| 65+ years (Seniors) | 70–85%+ | High likelihood of presbyopia + other changes (cataracts, reduced acuity/contrast). Majority will struggle with or be unable to comfortably read the full legal text and decipher fine map details without large-print version, strong magnification, or help from others. Higher risk of misinterpretation or skipping content. |
4.3 Comparison to Accessibility Guidelines
| Feature | Document (Est.) | Recommended for 45+/Seniors | Assessment |
| Body text size | ~9–11 pt | 14–18 pt (min 12–14 pt) | Below standard — significant impairment risk |
| Map legend text | ~6–9 pt (est.) | 12–14 pt preferred | Below standard — lower map especially problematic |
| Contrast | Black on white, but softened by photo | High (4.5:1+ ratio); sharp | Marginal — capture quality reduces benefit |
| Font style | Serif (small size) | Sans-serif preferred for clarity at small sizes | Acceptable but not optimal |
| White space / margins | Limited; cramped layout | Generous spacing, clear hierarchy | Below standard — increases fatigue |
| Text layer / reflow | None (image-only) | Searchable, reflowable, zoom-friendly PDF or Word | Major gap — prevents easy enlargement & accessibility tools |
5. PDF ACCESSIBILITY STANDARDS AND COMPLIANCE IMPLICATIONS
PDF accessibility ensures that documents can be perceived, navigated, and understood by people with disabilities, including those using screen readers, screen magnifiers, refreshable braille displays, or voice control. The primary international technical standard is PDF/UA (ISO 14289-1), which defines requirements for universally accessible PDF files. This standard aligns closely with WCAG (Web Content Accessibility Guidelines) 2.1/2.2 success criteria when PDFs are published online and is referenced by Section 508 of the U.S. Rehabilitation Act for federal agencies and many public-sector documents.
Core Requirements for Accessible PDFs include:
· Real selectable text layer — Text must exist as Unicode characters that can be searched, copied, and read by assistive technology. The current zoning ordinance is image-only (a photograph of a printed page) with no extractable text layer — a fundamental failure of PDF/UA.
· Logical tagged structure — Headings, paragraphs, lists, tables, and figures must be marked up in a hierarchical reading order. The current document has no tags or structure.
· Alternative text and extended descriptions — Non-text content (maps, charts, images) must have meaningful descriptions. No alt text or extended descriptions exist for the overlay zone maps.
· Sufficient color contrast — Text and important graphics must meet WCAG minimum ratios (4.5:1 for normal text). While the document uses black-on-white, the photographic capture reduces effective sharpness and contrast, exacerbating difficulties for users with age-related contrast sensitivity loss.
· Appropriate font sizes and reflow support — Content should remain usable when magnified without loss of meaning. The small dense text (~9–11 pt) and fixed photographic layout make clean reflow or comfortable magnification difficult.
· Declared language, navigation aids, and logical order — Language must be specified; bookmarks and proper tab order should be present where relevant.
Performance of the Current Document: The Frederick County zoning ordinance PDF fails multiple core requirements of PDF/UA and WCAG. It functions as a static photograph rather than a structured, machine-readable document. This creates significant barriers not only for blind and low-vision users but also for the broader population aged 45 and older. As presbyopia and reduced contrast sensitivity progress, many individuals increasingly rely on magnification, high-contrast modes, text-to-speech, or reflowable text — none of which this document supports effectively.
6. CONCLUSIONS
The Frederick County zoning ordinance document, while containing important legal and geographic information, is not optimally designed for comfortable or accurate reading by adults aged 45 and older, particularly seniors. The combination of sub-optimal font size, image-only format, photographic capture artifacts, dense layout, and map complexity creates unnecessary barriers. Many in the target population will experience preventable eye strain, slower comprehension, or incomplete understanding. This is especially relevant for a public planning/zoning document that may affect property owners, residents, and stakeholders across age groups. The additional failure to meet PDF/UA and WCAG accessibility standards further limits equitable access.
7. RECOMMENDATIONS
· 1. Produce an accessible version: Create a native digital PDF (or Word export) with selectable, searchable, reflowable text. Use 14–16 pt sans-serif body text (e.g., Arial or Calibri), 1.15–1.5 line spacing, and high-contrast styling.
· 2. Large-print / senior-friendly print edition: Offer a version at 16–18 pt with generous margins, increased white space between paragraphs and sections, and simplified or enlarged map legends (minimum 12–14 pt). Consider splitting complex maps or adding callouts.
· 3. Improve map design: Increase legend and label sizes; use higher-contrast colors/patterns for the overlay zone; ensure critical boundaries and text meet minimum legible sizes even when printed at letter size. Test with older adult users if possible.
· 4. Layout enhancements: Add more breathing room, clearer visual hierarchy (larger section headers, better separation of text vs. graphics), and avoid or enlarge the vertical sidebar text. Consider a multi-page format if density cannot be reduced otherwise.
· 5. Accessibility statement: Include a note offering alternative formats (large print, electronic reflowable, audio) upon request, consistent with best practices for public documents.
· 6. Future documents: Adopt county-wide standards for print and digital materials that incorporate age-friendly design principles from the outset (font, contrast, spacing, map guidelines).
