LANDSCAPE AND VISUAL IMPACT ASSESSMENT OF PROPOSED WIND TURBINES AT VORUKULA, ESTONIA

2. The objective of this assessment is to identify potential impact of this wind turbines which are 144m high including
the size of the blades, on the quality and character of the landscape. The study also assesses the predicted visual
disturbances that would be created by these wind turbines on people living and passing through the area. The aim
of the assessment of effects are to identify the effects of the development, estimate the magnitude of the effect,
assess the nature and significance of these effects and indicate the measures to be taken for avoiding, reducing
and compensating the effects.

5. STUDY OF SOIL CONDITION, ROAD NETWORKS, SETTLEMENT PATTERN, NATURE PROTECTED AREAS, FOREST
COVER, HYDROLOGY, CULTURAL HERITAGE AND PROTECTED AREAS TO DEVELOP THE LANDSCAPE CHARACTER
TYPES
1. SOIL CONDITION
The proposed wind farm area
represented mainly 5 different soil types:
1) LP- pseudopodzolic soils, 2)LPG-
pseudopodzolic gley-soils, 3)LPg- gleyed
pseudopodzolic soils, 4) GI- eluviated
gley-soils AND 5) M"'- deep swamp
soil
In view of soil types the
area is too damp and
soil is not good quality,
so area is not suitable
for cultivation. So, the
site is suitable for wind
farm.

6. 2. ROAD NETWORKS
The site is connected to one primary road
which is Tartu-Räpina-Värska highway
and it is located to north-east of the site.
In addition to the surrounding of the site
there are four asphalted roads: Vana-
Kastre-Roiu (located to north to south of
the site), Melliste-Heiti (located to east to
south of the site), Sillaotsa-Kriimani
(located to south of the site), Tõrvandi-
Roiu-Uniküla (located to south of the
site). The others are smaller and gravel
roads.
In general, the roads are poor conditions
because the roads are narrow and
curved, especially near on the site.

7. 3. SETTLEMENT PATTERN
The proposed wind farm is located in
Mäksa Parish, Võruküla village. Võruküla
village settlement is concentrated to
northwest of the site. Võruküla village
population is 47 inhabitant (2013 year
data).
Settlement around the site is distributed,
so the settlement pattern is not
clustered.

8. 4. NATURE PROTECTED AREAS
Within 2 kms, there are not so many
important nature protection and Natura
2000 areas. The nearest nature protection
areas are approximately 2-4 kilometers
away: Age oru special conservation area
(located to southwest of the site), lake
Lavatsi special conservation area (located
to southeast of the site). Kaagvere manor
park (located to north of the site).
5. FOREST COVER
In this map we can also see the forest
coverage. Near to the study area is a lot of
forest area, especially to west and south of
the site.

9. 6. THE WATER BODIES
The proposed wind farm is surrounded
with different water bodies: lakes, rivers
and streams. The nearest (~ 2 km) water
body is lake „Kaikjärv“, which is located to
east of the site. The biggest lakes are
„Poka“ and „Lavatsi“, which are located
also to east and approximately 2,5
kilometres away study area. Lake Lavatsi
has special conservation area, so it is
protected. Other water bodies located
more than 3 kilometers away study
area:1) lakes: Melliste, Kaanjärv,
Kriimani, Kitseküla, Roiu, Tammejärv,
Agali, Kurepalu artificial lake, 2)rivers:
Emajõgi, Mõra, Luutsna, 3)streams:
Melliste.

10. 7. CULTURAL HERITAGE PROTECTED
AREAS
The nearest cultural heritage area is
ohverdamiskoht "Kiigeoru hiiesalu".
Cultural heritage areas away from the site:
Ohvriallikas "Silmaläte". Ohvriallikas
"Põrguvaluläte". Linnus "Lingutusmägi".
Kivikalme "Vareslepik". Vana-Kastre
linnuse territoorium, 13-16. saj. Kaagvere
manor park buildings (Kaagvere manor
park, Mõisaase, Kaagvere mõisa kuivati,
Kaagvere mõisa valitsejamaja, Kaagvere
manor basement)

15. Initially the locations of the viewpoints were identified with help of Google maps and Google street view. Points
were selected and maps with field survey sheet completed. The field trips were carried out by car soon after the
materials were prepared and the places selected before were visited. The main points were visited, described and
photos taken. Some new possible points were found on the way. The information from field trip was put together
and evaluated during second group meeting. More possible viewpoints were selected with help of Google maps
and Maa- Amet. With this groundwork we analyzed our points in the virtual landscape studio to make sure our
presumptions were correct or not. Virtual studio helped us to find even more possible viewpoints. We finished layers
for landscape character assessment before our second field trip. We did another field trip and visited rest of the
viewpoints which we could access. Some of the points confirmed what we saw in visual studio and some of them
showed different thing. We came back and organized two more group meetings during which the photomontages
were done using mostly real photos as background. Sketches, maps, tables for visual impact assessment,
methodology of our group work and conclusion was done.

32. CUMULATIVE LANDSCAPE AND VISUAL IMPACT
The cumulative landscape and visual effect may result from an individual project that is being assessed interacting with the
effects of other proposed development in the area. It was found at the site and surrounding landscape that there was no
such development occurring that significantly will alter the skyline.
The visual impact of wind turbines together towards north and north east of the site interacts with the forest covered elevated
ground and industrial chimneys which may reduce the severity of visual impact wind turbines. There are many
telecommunication masts visible and form important feature of this skyline.
There may be an incremental change in the landscape and visual impact when all wind turbines are installed and become
fully operational. There may be a cumulative landscape and visual impact of building other infrastructure such as power
houses and maintenance tracks to the wind turbine location.
Wind turbine proposed at Vorukula are on the forest cover or just on the edge, so has a unique character in the area. It’s a
wet forest patch where the installation of wind turbine would lead to clearing of forest which would lead to permanent loss of
forest, however it doesn’t have many significant areas of impact.

33. MITIGATION MEASURE
The mitigation measures are proposed to reduce the impact of wind turbine on specific receptors. Mitigation
measures can be selected based on the sensitivity of the receptor and the magnitude of change that specific
turbine impose on the receiving environment.
The mitigation measures for sever adverse impact on the receptors located within 0-2 Km follows:
1, 2,3- Hedge and tree plantation, 4,5- hedge, tree planting and change of colour of the turbine, 6- hedge, tree
planting and suitable colour of turbine,
The mitigation measures for severe adverse impact on the receptors within 2-5 Km follows:
16- Tree planting in the park edge and change of colour of turbines, 15, 12,13- suitable colour of turbine
depending on the back ground. 8,7- No significant impact as the area doesn’t allow visibility due to forest
coverage.
The mitigation measures for severe adverse impact on the receptors within 5-10 Km follows:
18, 20- In the major adverse situations where they face the clear visibility of turbines, where turbines can be
coloured and there shoul be road plantation. 9- change of colour of blades can make some difference to the
impact.
The receptors have moderate adverse impact on receptors can consider change of colour and road side
plantation as effective mitigation measure. The receptors receiving minor impact can be mitigated through
hedge and tree planting along the road or near houses and change of colour of turbine.
