Pocket Guide to Rapid Site Assessment
This pocket guide is an easy-to-use step by step tool to rapid IDPs emergency sites assessments. It is intended as a quick reference in the field to capture maximum information about a specific site within a limited period of time. Editor: Ghada Ajami Solidar/SCC Illustrated and translated by: Yasotha Ponnampalam First Edition August 2007
Pocket Guide to Rapid Site Assessment
Before you leave to the field: Be prepared with the following:
1. Assessment forms. 2. Sites list. 3. Notebook for additional observations. 4. A pen, a pencil and an eraser. 5. A camera. 6. Know your PF (Pace Factor). See p.4 7. 20m length measuring tape. 8. A GPS if possible.
If you are assessing a new open site you need to have: • The site approval by the GA or the DS. • The land officer or the GS/GN of the area where the site
is located to point out the boundaries of the land. If you are assessing a communal building site make sure you have: • The GA/DS approval. • The permission of the relevant government department
responsible for this site (eg. Zonal Director of Education/ZDE if the site is a school, the bishop of the area if the site is a church, etc…)

Once on Site To achieve a comprehensive site assessment: • Talk to the local population and ask questions. • Check and cross check information you collect. • Walk the site. • Use the remarks column on your assessment form for
additional information. • Note down your observations • Sketch the site.

Pocket Guide to Rapid Site Assessment
1. Site Location, Boundaries and Ownership Make sure you are looking at the right site: • Ask the land officer or the GN/GS about the boundaries
of the site. • Verify the ownership status from the land officer. • Make a rough sketch on the site. • Know which direction is North and mark it.
Properly identify the site location: • Plot any existing landmarks (temple, church, school,
government building…or features (statues, check point, big tree…) on the sketch plan.
N

• Write the names of the prominent landmarks.
Take photos of the site including site features, landmarks. In the Site Location Section indicate the following in the remarks column:
6
Pocket Guide to Rapid Site Assessment
Approximate travel distances (by foot or 3 wheeler or bus from the nearest town or village center.
The name of the site/ building of culture significance 2. Size of Site If the site is irregular in shape measure the average length and the average width. You can get site dimensions by: a) Using the measuring tape. b) Pacing the average length and width of the site. (Refer to annex 1). c) Estimating dimensions by visual referencing using existing fence posts, power posts, trees spaced at equal distances. (Refer to annex 2) Tip: On some occasions you can combine 2 or more of the above methods determine different measurements of the site.

3. Site Security To get an idea on the safety of the site location: a. Ask the local population in the area how loud and
how often do they hear shelling. b. Check if there has been security related incidents in
the recent past. Indicate on the assessment form/site sketch:
Approximate distances from artillery range, mine fields, military posts/camps.
8

4. Site Drainage Site drainage is important in deciding the positioning of the shelters and latrines in the site. The type of soil indicates its absorption capacity. • Ask the local population if the area floods during the
rainy season. On the site sketch:
Indicate the direction of the slope of the site on the site sketch.
9
Pocket Guide to Rapid Site Assessment
5. Site Vegetation On the assessment form:
Specify if the site clearance can be done by labor or if there is need for heavy machinery. 6. Access to Site On the assessment form specify if:
The access to the site is a through main road, or a secondary road.
There is a need to build internal roads inside the site is drivable. 7. Host Community If local population is already hosting IDPs try to know: • The area of origin of these IDPs. • The duration of the displacement.
Note this information down on the assessment form.
10
Pocket Guide to Rapid Site Assessment
8. Water and Sanitation • Check with local population if water table is high or not. • Check the quality of water in the wells on site and in the
surrounding area (potable, brackish…) • Ask local population if the wells have water in the dry
season, if the water is enough for drinking, surplus, etc…)
On a sketch:
Mark the existing wells and latrines on and adjacent to the site.
11
Pocket Guide to Rapid Site Assessment
On the assessment form, indicate:
Indicate the number of existing wells and latrines on site and their condition. (Annex 3)
Specify if the wells are open or closed wells in the remarks column.
9. Livelihood On the assessment form mention:
If the market, agricultural land or sea is within walking distance or if there is a bus route available to commute to these areas.
9. Services On the assessment form, specify:
The type of health center: clinic or hospital.
The type of school: Pre school (year 1-5). Higher elementary school (year 5-10).
12
Pocket Guide to Rapid Site Assessment
On Extension of Communal Building Sites: Similar procedure as above plus the following: 1. Draw existing facilities. 2. Mark entrance points to sites. 3. Indicate possible extension areas.

Pocket Guide to Rapid Site Assessment
ANNEX 1 Pacing In some situations where it is difficult to use a measuring tape or an instrument to measure the site, distances may be roughly calculated by pacing to determine the approximate area of a site. A pace is the normal length of a step or stride of an individual. To determine your pace factor (PF) follow the steps below: 1. Measure a distance of 100m using a measuring tape. 2. Walk the distance with your normal pace. 3. Count the number of paces. 4. Divide the distance by the number of paces to get your pace factor (PF).
PF = Measured Distance
# of Paces
14
Pocket Guide to Rapid Site Assessment
Example: PF = 100 meters = 0.8m
125 paces
To determine an approximate measurement on site:
1. Pace the distance you want to measure. 2. Count your paces as you move along. App. Measurement = PF X Number of Paces Example: If # of paces = 120 and your PF = 0.8m Approximate measurement = 0.8 X 120 = 96m
15
Pocket Guide to Rapid Site Assessment
Recommendations: - For more accurate distance measurement, whenever time allows, pace the distances in both directions (from point A to Point B and then from point B to Point A). Determine the measurement by calculating the average. Distance = (AB+BA)
2 - In irregular sites, use triangulation method. Break the site into smaller more regular rectangles and pace the diagonals.
16
Pocket Guide to Rapid Site Assessment
ANNEX 2
Visual Referencing: Another way of estimating measurements on site is visual referencing. For example, if the fence of the site consists of posts at equal intervals, the average distance between 2 posts can be used as a reference to determine the approximate measurements of the site. Approximate Measurement = n x m Example: If the posts of the site fence are spaced at modular interval = m = 2m Number of modules per side = n = 23. App. Measurement = 23 x 2m = 46m
