The total cost of the Eiffage project was €618 million, including €282 million for the stadium, €42 million for additional development such as parking, hotels, and restaurants, and €96 million to ensure seismic standards were met. This latter requirement was introduced in 2011, following a new law passed in the wake of the massive Japan earthquake and tsunami. The cost was spread between the city of Lille (€24.7 million annually for 31 years), the LOSC (€7.5 million annually) and the Nord-Pas-de-Calais regional council (€45 million).
