You can use border-radius: 0 0 50% 50%; to make the whole bottom part round. With adding a white pseudo element ::after, you can "cut" the unwanted upper part to only show the curve:

.rounded {
  border-radius: 0 0 50% 50%;
  display: block;
  background: #669999;
  width: 100%;
  height: 70px;
  margin-top: -35px;
.rounded::after {
  content: "";
  display: block;
  width: inherit;
  height: 35px;
  background: white;
<div class="rounded"></div>
