This project has received funding from the European Union’s Horizon 2020 research and innovation programme under Grant Agreement No. 730052

Topic: SCC-2-2016-2017: Smart Cities and Communities Nature based solutions

The area Lagaccio

The Genova’s Lagaccio district is a

central and densely populated

district characterised by

disorganised post-war urbanisation

mainly formed by residential

multi-storey buildings and derelict

sites.



The municipal urban plan identifies the area as a transformation district, recognizing its strategic importance for the city.

The plan provides for the reduction of waterproof spaces and requires the planting of trees.

The creation of green spaces must contribute to the ecological connections of the sitealso through the widening of the bands vegetate on the east and west sides of the area.



The urban park



Adopted Nature Based Solutions

Permeable paving

Description:

- surfaces for vehicular and

pedestrian use made of

resin-bound gravel

- Surfaces for pedestrian

use in limestone with an

eco-compatible binder

Expected impact:

Surface runoff water

reduction through direct

infiltration into the ground or

drainage to the disposal

network




Sandpit

Description:

Shallow depression filled with

soft sand located in the play

area to offer an experiential,

playful surface linked to

natural elements.

Expected impact:

Drainage of rainwater into the

ground




Description:

Wetland with hygrophilous

vegetation

Expected impact:

Temporary detention of

rainwater, partial drainage,

runoff water surge balancing,

and water quality

improvement by riparian

vegetation, increased

biodiversity.




Infiltration basin

Description:

Vegetated depressions

designed to store hillsides

runoff water

Expected impact:

Drainage of rainwater into the

ground




BioswaleDescription:

low depth ditch with variable

width, with gravel bottom and

hygrophilous vegetation

Expected impact:

Detention and infiltration of

surface runoff water from the

hillsides, increased

biodiversity




Tree groups and green areasDescription:

Tree planting in both isolated

specimens and groups

distribution, new lawn areas

creation.

Expected impact:

Increased shading surface,

C02 absorption, reduction of

heat island effect, partial

absorption of rainwater,

increased biodiversity




Orchard and xerophilous meadowsDescription:

Recreational areas with rustic

xerophilous lawn and

autochthonous fruit trees

Expected impact:

Hydrogeological risk reduction,

local biodiversity increase,

water saving, educational

value.




Reforestation of steep slopesDescription:

Forestation of steep slopes

with no vegetation. The

experimental use of

biodegradable devices is

planned to achieve irrigation

efficiency in limited areas.

Expected impact:

Greater resistance to long

periods of drought, slope

stabilization, increased

biodiversity




Green wallDescription:

Independent metal framework

to support evergreen climbing

plants

Expected impact:

Visual mitigation of uncovered

facades, increased leaf-

covered area for

evapotranspiration, increased

biodiversity.




Tree log retaining wallsDescription:

Natural engineering

techniques intended for

ground support and

consolidation, characterized

by the use of wood elements

and living material (Salix spp

cuttings)

Expected impact:

Drainage of rainwater, soil

stabilization, increased

biodiversity.




GabionsDescription:

Wire mesh gabions filled with

crushed debris used with three

differnet functions:

- retaining walls

- steps with seats

- parapets

Expected impact:

Hydrogeological risk reduction,

local biodiversity increase,

saving on materials and

resources




Stormwater retention vaultDescription:

subsurface concrete vault

used to store excess

stormwater runoff for later

irrigation use.

Expected impact:

Hillsides runoff water

retention, water supply for

irrigation



Latest progress

� the hydraulic risk mitigation project of the Rio

Lagaccio was approved, a tender was

completed and work will start soon

� the Urban Park Project was approved, the

tender was completed and work will start by

the end of 2019
